Authors: Hamad Abdallah M.B. Abu , Amireh Belal , Jasper Andre , Uhl Dieter
Published: September 2022

This contribution provides new palaeobotanical data from the Jarash Formation (Lower Cretaceous, Aptian–Albian) of NW Jordan. On the one hand it provides the first anatomical evidence for the occurrence of palaeo–wildfires in the Jarash Formation near the town of Jarash in NW Jordan, and, on the other hand, it provides a preliminary taxonomic assessment of the palaeoflora from a recently discovered locality nearby in the same formation. This flora consists of ferns assignable to Weichselia reticulata (Stokes et Webb) Fontaine in Ward and a so far unidentifiable taxon, conifer needles of Agathis levantensis Poinar & Milki and angiosperm leaves which can be attributed to the Platanaceae Sapindopsis cf. lebanensis. The latter taxon was so far only known from the Cenomanian of Lebanon.

Published: September 2022

Well preserved plant fossil assemblage recorded for the first time from the Barakar Formation of Sharda Open Cast Mine, Sohagpur Coalfield, Shahdol District, Madhya Pradesh is documented in this study. The assemblage comprises the orders Equisetales, Glossopteridales and Cordaitales. Equisetales is represented by unidentifiable leafless equisetalean axes bearing nodes and internodes, Glossopteridales comprises one species of Gangamopteris (Gangamopteris intermedia) and seven species of Glossopteris (Glossopteris communis, G. gigas, G. giridihensis, G. indica, G. longicaulis, G. spatulata and Glossopteris sp.), and Cordaitales is known by one species of Noeggerathiopsis (Noeggerathiopsis hislopii). The floral assemblage is broadly comparable with those described previously from the Barakar Formation of Damodar, Mahanadi, Wardha, Godavari, Rajmahal and Satpura Gondwana basins of India. Since the known records of plant mega fossils from the Barakar Formation of Sohagpur Coalfield are meagre, recovery of quantitatively and qualitatively rich plant fossils from the Sharda Open Cast Mine substantiates the geological and geographical distribution of the Glossopteris flora in India in general and that of the Sohagpur Coalfield in particular, and reflects its significance in the formation of coal in the area.
Insect herbivory in Gondwana plants
Authors: Srivastava Rashmi , Srivastava A.K.
Published: September 2022

Plant–insect interaction is dominant in the extant flora and it is estimated that more than one million species of insects directly or indirectly survive on plants. In comparison, such association is limited in extinct flora, mainly due to problem in identifying structural features associated with the insect wronged plant fossils. Concerted efforts and comparative structures observed in extant flora have unfolded the mystery of insect herbivory in fossil plants. The study has helped to understand the feeding pattern and evolutionary features of insects during different time intervals and provide significant evidence to comprehend the co–evolution of plant and insect in the geologic past. Herbivorous insect wings discovered from different Gondwana successions of India belong to families and genera of Homoptera, Heteroptera, Mecoptera, Coleoptera and Blattoidea. The remains of Coleoptera and Mecoptera in all probability represent the earliest record in fossil flora. Insect herbivory is well recognized in Indian flora in the form of insect galls, chewing and eaten marks of leaf margin, disfigurement of lamina, egg–like pouches, trailing marks, mining activity, etc. The available records demonstrate the presence of well-knit coalition of insect–plant interaction in Indian Gondwana successions.

Diverse type of insect herbivory recovered in the Gondwana flora of India implies that insects used the plants for various purposes such as feeding, shelter and laying eggs for their development/ survival and the process has thus helped in the development and evolution of insects in consortium with plants.
Late Permian palynoassemblage from Borehole No. WG-22 near Sekapur, Wardha District, Maharashtra, India
Authors: Sarate Omprakash S. , Murthy Srikanta , Kalkar S.A.
Published: September 2022

The present paper deals with the palynological investigation of the Lower Gondwana sequence intersected in Borehole No. WG–22, drilled near Sekapur Village, in Wardha District, Maharashtra. The study divulges the incidence in significant proportion and with consistency of striate bisaccate palynomorphs, viz. Striatopodocarpites and Faunipollenites and non–striate genus Scheuringipollenites. The associated genera recorded include, Weylandites, Tiwariasporis, Densipollenites, Verticipollenites and Klausipollenites, though with meagre distribution. This palynoassemblage has been dated as Late Permian and affiliate closely with the palynofloral assemblages known from the basal part Raniganj Formation of East and West Bokaro coalfields, Damodar Basin, Makardhokada area of Nagpur District and vast areas of Godavari Valley. The study indicates that almost similar vegetational pattern existed in the Nagpur, Wardha–Godavari and Damodar basins however, there existed regional variations in the generic composition of the vegetation in Satpura Basin as suggested by their palynofloral contents. The mega– and microfloral studies of the Wardha Basin with particular reference to Sekapur area suggests prevalence of warm and temperate climate in this region.
Early Cretaceous flora of India- A review
Authors: Rajanikanth A. , Chinnappa Ch.
Published: September 2022

Earth’s terrestrial ecosystem during the early Cretaceous was marked by the dominance of naked seeded plants and appearance of flowering plants. Tectonic changes and evolutionary processes affected southern floras of the globe during this time. Review of Indian early Cretaceous flora distributed in peri and intra–cratonic basins signify homogenity of composition with regional variations. The flora composed of pteridophytes, pteridospermaleans, pentoxylaleans, bennettitaleans, ginkgoaleans, coniferaleans, taxaleans and taxa of uncertain affinity along with sporadic occurrence of flowering plants represent a unique Indian Early Cretaceous flora. Similitude of basinal floras with marginal differences can be attributed to taphonomic limitations and taxonomic angularity. A perusal of available data brings out an opportunity for novelty in floral composition and variable associations dictated by prevailed environmental conditions. The eastern, western and central regions of India hold distinct litho units encompassing plant mega fossils represented by leaf, wood / axis, seed, fructification and associated marker forms. Remarkable tenacity of certain plant groups, which even found in modern flora and vulnerability of many taxa constitute a blend of extinct and extant. The appearance and extinction of certain taxa can be explained as a cumulative affect of evolutionary and climatic factors. Perpetuation of gondwanic floral elements during the early Cretaceous along with newly evolved floral components testifies evolutionary innovations and changing ecological constraints.
Behavioural studies on the pollen grains of Pinus roxburghii collected from Lucknow, India- A report
Authors: Dixit Pooja , Saxena Gauri , Kumar Dinesh , Singh Lav
Published: September 2022

We have long recognized that natural climatic shifts influence the development of plants on earth. These slow temperature fluctuations have resulted in either the extinction or evolution of various species. A careful study of the comparative morphology of the living and fossil type suggests that the modern coniferous families originated independently from a group of extinct conifers called the transition conifers by Florin. The conifers reached their climax in the mid–Mesozoic times and have been on the decline ever since. Pinaceae is one such family whose pollen grains have been located as long back as in the Gondwana flora and have demonstrated morphological variations since then due to climatic changes.

Pinus is the most dominating genus of the family Pinaceae in gymnosperms. Pine grains are large due to their sacs or bladders, which make them one of the easiest pollen grains to identify. They are rich in non–enzymatic anti–oxidants, like provitamin A, B complex, C, D and E plus a host of minerals and amino acids. Apparently pine pollen is also a great defense against radioactive caesium that is appearing in dairy and other foods in the U.S.

The present study examines the changes occurring in one of the most sensitive phases of plant development in the living genus of Pinus, i.e. the behaviour of pollen, found to be dependent on number of genetic or environmental factors. The major environmental factors contributing to this abnormal behaviour include light intensity and quality, temperature and moisture and level of pollutants in atmosphere.

During present study, the Pinus cones were collected from five experimental areas of Lucknow that exhibited different level of deformities probably due to different levels of environmental stress or other genetic reasons. The clusters were unique in having deformed cones on the side facing the road while they were near normal on the side away from road indicating that the area around the roadside being more polluted and may be playing a detrimental role in cone morphology. Pollen of normal cones were bilateral, analept, usually bisaccate, spherical, slightly elliptical with verrucate corpus and sacci having pila, normal average size being 60μ–65μ including sacci and sacci attached almost full width of corpus, exine thick in proximal part of reticuloid corpus. While pollen grains of abnormal cones show abnormalities in their size, shape, size and number of wings, size and shape of corpus and development of pollen tube within microsporangium. The abnormalities were observed using scanning electron microscopic studies and its percentage was calculated using a light microscope.
A fossil dicotyledonous wood of Ochnaceae from the Deccan Intertrappean sediments of Mahurzari, Nagpur District, Maharashtra, India
Authors: Ramteke D.D. , Kapgate D.K.
Published: September 2022

The paper describes anatomical details of fossil wood of family Ochnaceae, Ochnaceoxylon tertiera from the Deccan Intertrappean sediments. The wood is preserved in silicified chert from the Deccan Intertrappean beds exposed in a quarry near the village of Mahurzari, India about 14 km from Nagpur (lat. 21º13.280' N, long. 79º0.84' E). The wood described here is silicified measures about 10.5 cm in length and 4.6 cm in diameter. Its detailed anatomy is studied through Transverse Section (T.S.), Tangential Longitudinal Section (T.L.S.) and Radial Longitudinal Section (R.L.S.) planes. The wood is diffuse porous, vessels are mostly solitary and few are in multiples of two to three. Perforation plate is simple and obliquely placed; rays are biseriate to multiseriate and heterogenous, tyloses present. The wood is compared with modern families like Apocynaceae, Dipterocarpaceae, Ochnaceae and Ericaceae. The reported fossil wood shows close resemblance with modern family Ochnaceae. Members of the family Ochnaceae are evergreen, mainly small trees or shrubs, and are presently distributed in tropical and subtropical forests and Savannas. The existence of wood shows the palaeoecological evidence during Maastrichtian.
Palynology and palaeoenvironment of Late Permian Sawang OCM, East Bokaro Coalfield, Damodar Basin, India
Authors: Murthy Srikanta , Rajanikanth A.
Published: September 2022

Palynodating of Sawang Open Cast Mine (OCM) section from East Bokaro Coalfield, Damodar Basin has been done. Recovered palynofossils are characterized by the dominance of Striatopodocarpites–Faunipollenites complex. The other stratigraphically significant taxa recorded from this section are Guttulapollenites hannonicus, Crescentipollenites fuscus, Rhizomaspora indica, R. triassica, Distriatites sp., Weylandites lucifer, Microfoveolatispora gondwanensis, Dictyotriletes invisus, Indotriradites spp., Arcuatipollenites pellucidus, Alisporites indicus and Klausipollenites schaubergeri. Other rare palynotaxa include Parasaccites, Corrisaccites, Dicapipollenites, Striomonosaccites, Barakarites, Plicatipollenites, Scheuringipollenites, Densipollenites, Callumispora, Tiwariasporis, Praecolpatites and Distriatites. On the basis of the total palynocomposition, the studied section has been dated as Late Permian age. This age correlation also gets support from comparative studies with similar palynoassemblages known from other coalfields of Indian Gondwana basins such as Damodar, Son–Mahanadi, Rajmahal, Wardha–Godavari and Satpura basins of India and from known Gondwanan continents. Palynofossil evidences indicate prevalence of warm and humid conditions. The dominance of conifers and subdominance of Glossopterids, cordaites and low percentage of triletes (filicopsids and lycopsids) suggests that the Inland Sawang OCM was deposited under freshwater environment.
Studies on pollen deposition pattern in relation to modern vegetation of flood prone region in Assam, India
Authors: Basumatary Sadhan Kumar
Published: September 2022

This paper presents a palynological dataset on Pashumara Wetland and Ranga Reserve Forest to differentiate flooded and non–flooded area in relation to existing vegetation in Assam. Study reveals that the palynoassemblage in Pashumara Wetland is an admixture of arboreal local and extra–local taxa and not fully matches with present vegetation. The various pollen distributions were observed in continuation to study sites and confirmed that pollen deposition pattern in wetland depends on parent plant growth, flood activity and surrounding vegetation. Presence of broken pollen is indicative of long distance transportation under a fluvial environment. The palynoassemblage of Ranga Reserve Forest located in non–flooded area to display modern pollen and vegetation relationship and identification of local arboreal taxa in the region. The main forest elements include Syzigium, Lagerstroemia and Emblica in the palynoassemblage are suggestive of presence of tropical deciduous forest under warm and humid climate. Pollen clumps in the palynoassemblage signifies their local origin and entomophily. This generated palynodata could be precisely utilized to distinguish flooded and non–flooded area and to interpret palaeovegetation and past climate changes in relation to palaeoflood episodes by the analysis of wetland core from the region and to correlate other tropical flood prone region of the globe.

Authors: Prasad Mahesh , Alok  , Kannaujia Ankit Kumar , Kumar Sanjeev , Singh Sanjai Kumar
Published: September 2022

Morphotaxonomical study on the plant fossils (leaf and fruit impressions) collected from Lower Siwalik sediments of Tanakpur area, Uttarakhand revealed the occurrence of 57 species of 25 angiospermous families. Of these, 39 species have been recorded new to the fossil flora of Himalayan foot hills and remaining 18 species are reported already from different Siwalik fossil localities of India, Nepal and Bhutan. The family Fabaceae (Legume family) represented by 15 species is the most dominant family in present assemblage followed by Annonaceae (8 species), Sapindaceae (5 species), Lauraceae and Euphorbiaceae (4 species) and Dipterocarpaceae and Rutaceae (3 species). The family Fabaceae which appeared in Upper Palaeocene became a major component of the evergreen forest during Middle Miocene times all along the Himalayan foot hills. In the present assemblage the evergreen floral taxa (54%) are dominant in contrast to mixed deciduous taxa at present. The predominance of evergreen elements in the Siwalik fossil assemblage indicates the prevalence of warm and humid climate with plenty of rain fall during the deposition of Siwalik sediments.

The analysis of present day distribution of all the recovered species from the Siwalik foreland basins of Tanakpur area shows that they are mostly known to occur in North–east India, Bangladesh, Myanmar and Malaysia wherever favourable climatic conditions exist. Only about 14% taxa of the total assemblage are found to grow presently in the Himalayan foot hills and the remaining 86% taxa are locally extinct, suggesting changes in the climatic condition. Nearest Living Relative (NLR) suggests that the Tanakpur area enjoyed a tropical climate having Mean Annual Temperature (MAT) 24–28ºC and Mean Annual Precipitation (MAP) 2100–2800 mm during the deposition of the sediments.
New fossil leaves of Annonaceae and Achariaceae from Churia Group of Nepal and their phytogeographical implications
Authors: Prasad Mahesh , Gautam Somlata , Bhowmik Nupur , Kumar Sanjeev , Singh Sanjai Kumar
Published: September 2022

Study on the fossil leaves recovered from Churia Group of Arjun Khola area, western Nepal revealed the occurrence of five new fossil species, four belonging to the family Annonaceae and one to Achariaceae. The analysis of present day distribution of the comparable extant species, Unona longiflora Roxb., Annona reticulata Linn., Goniothalamus macranthus (Kurz) Boerlage, Artabotrys speciosus Kurz and Ryparosa caesia Blume ex Baill of fossils indicates that they do not grow in and around the study area as well as sub–Himalayan zone of India and Nepal but are presently distributed in the evergreen forests of north–east and south India and South–east Asian region. This suggests that after Miocene these taxa could not survive there most probably due to onset of drier conditions. Based on the data available the phytogeographical aspect of these fossil taxa of both the families has also been discussed.
Palynostratigraphic, palaeoenvironmental and palaeogeographic significance of the Early Cretaceous palynoflora of Kachchh Basin, western India
Authors: Kumar Madhav
Published: September 2022

Sediments of Bhuj Formation (Early Cretaceous) occur in the Kachchh Basin, western India containing abundant and diverse plant fossils. Sedimentary successions of the formation exposed along Pur River comprise variably thickened shale, carbonaceous shale, thin coal seam, siliceous clays, etc. and have yielded abundant megaspores, microspores, conifer pollen grains, dinoflagellate cysts and colonies of Botryococcus alga. Two palynozones are recognized in the recorded palynoassemblage, viz. Minerisporites cutchensis megaspore zone at the basal part, derived mostly from herbaceous vegetation growing along pro–deltaic swampy habitat. The succeeding Araucariacites australis zone in the upper part of the succession probably derived from conifer–dominated forest inhabited along the freshwater swamps, flourishing in a more humid and warm temperate climate. The palynofloras of both palynozones are biostratigraphically very significant indicating Late Aptian–Early Albian age of the succession. A majority of the palynotaxa recorded from the studied sedimentary succession show resemblance with the contemporaneous deposits of other Gondwana continents of the Southern Hemisphere.
Geochemistry of coal–bearing Permo−Triassic strata in Allan Hills, South Victoria Land, Antarctica: Implications for palaeoclimate
Authors: Pandita Sundeep K. , Siddaiah N.S. , Tewari Rajni , Chatterjee Sankar , Agnihotri Deepa
Published: September 2022

Major, trace and rare earth element (REE) geochemistry has been carried out in this paper to characterize source–rock weathering and climatic variability of the late Permian Weller Formation and the late Triassic Lashly Formation of Gondwana sequences which have yielded rich record of plant mega–and micro fossils associated with coal beds in post–glacial conditions in Allan Hills of South Victoria Land, Antarctica. The geochemistry suggests dominantly a felsic provenance with a volcanogenic input and role of weathering and hydrothermal alteration. The palaeoclimatic interpretation derived from geochemical analysis indicates warm, temperate and humid conditions during the late Permian, and warm and humid conditions during the late Triassic.
Palynology of Cenozoic successions of Kerala Basin: a review from the perspective of biostratigraphy and palaeoclimatic studies
Authors: Verma Poonam , Singh Abha
Published: September 2022

The Kerala Basin is only onshore opportunity to study Cenozoic palaeoclimate and palaeoenvironment of southwest India encompassing Neogene global events such as Mid Miocene Climate Optimum (MMCO) and even older times of Palaeogene. The global warming during ~17–15 Ma (MMCO), enhanced annual surface temperature 3–4° C higher than the present, is equivalent to the warming predicted for the next century. Since the palaeogeographical and other general conditions have not been much changed from the Miocene Period, Neogene palaeoclimate of Kerala Basin can be considered as a possible analogue for future climate. Many workers have studied the Cenozoic sedimentary successions of surface and subsurface for stratigraphic classification of the rocks, but still, discrepancy persists in the chronostratigraphic relationship in sedimentary successions. The palynological investigations have also been limited mainly to palynofloral and palaeoecological inferences except a few in which palynostratigraphy, correlation and age have been attempted on the basis of spore–pollen only. Major three Cenozones namely, Triangulorites bellus and Crassoretitriletes vanraadshooveni (Eocene–Oligocene) and Malvacearumpollis bakonyensis (Miocene) have been established. The palynological studies done in the region broadly suggest warm and humid climate with heavy rainfall. However, the recent quantitative studies have highlighted the complexity of palaeoclimatic evolution in the tropics in terms of monsoon. A time–constrained quantitative palaeovegetation and palaeoclimate reconstructions on the basis of palynology is required for evaluation of response and changes in the tropical flora of northwestern India across the major climate events. For that, the biostratigraphy of finer resolution based on systematic and integrated multi–biotic proxy is needed to establish an age model for these sedimentary successions.

The objective of the study is the simple assessment of kerogen type in Barren Measures Formation shale using palynofacies. The Barren Measures Formation sandwiched between the coal–rich formations consist of organic–rich black carbonaceous shales. These ̴ 1000 m thick, black shales are in the productive gas window having kerogen types III with excellent gas generation potential as proven in recent pyrolysis studies. In this study, the palynological analysis of the four core samples of the Barren Measures Formation shale was done. The analysis has revealed three types of kerogen assemblages, viz. palynomorphs, phytoclasts and amorphous organic matter. The palynomorph assemblage consists of spores and pollen; phytoclasts consist of secondary xylem wood macrophyte plant debris and amorphous organic matter is a higher plant decomposed product. Based on the application of published kerogen classification and correlation of Tyson (1995), the pure kerogen type in these shales is categorized as mixed type; type II (oil prone) and type III (gas prone). However, the gas–prone kerogen assemblage gets relatively dominant in the samples from greater depth in the studied borehole. Our results are analogous to the previously published outcomes of kerogen typing evaluated using Rock–Eval pyrolysis experiments.
Evidence of wildfire based on microscopic charcoal, spores and pollen grains from Early Cretaceous sediments of South Rewa and Kachchh basins, India
Authors: Kumar Madhav
Published: September 2022

Early Cretaceous sedimentary successions in South Rewa and Kachchh basins of India comprising well–preserved macro–and microscopic biota, are considered to be significant late Gondwanan Lagerstätte of this epoch. Several sedimentary successions of the Bansa Formation in South Rewa and Bhuj Formation in Kachchh basins also contain abundant charcoalified plant fragments and thermally altered spores and pollen grains, indicating effect of fire on the vegetation during the deposition of sediments. Light and scanning electron microscopic images of the fire affected plant remains exhibiting less to severe morphologic distortions, viz. rupturing, shrinkage, curling and perforations due to stress and weight loss. The changes observed in their colour from pale yellow to brown, dark brown and black are most conspicuous and primarily related to the high temperature effect before their burial in the sediments. Botanical affinity of these thermally altered and unaltered spores, pollen grains, charcoalified and non–charcoalified woody fragments indicates their derivation from the vegetation constituted mainly by Pinales, Cycadales, Bennettitales, Ginkgoales, tree ferns and other herbaceous pteridophytes. Record of the charcoalified plant fossils from various sedimentary successions of both the basins provides evidence of the wildfire phenomenon during the Late Gondwanic regimes in India.
A technique for the extraction of palynomorphs from the Eocene amber
Authors: Verma Poonam
Published: September 2022

Amber is fossilized form of resin produced as the metabolic exudates from plants that serve defensive and protective biological purposes as well as other ecological functions. By virtue of excellent preservation potential of the amber, a diverse array of biota in extraordinarily pristine condition was recovered within the fossilized resins from Cambay Basin. In the present study, a new extraction method has been devised to retrieve palynomorphs from the early Eocene Vastan amber, Cambay Basin, Gujarat. The method was found useful for the extraction of organic matter and better yield of spore–pollen. The extracted significant palynomorphs such as Dipterocarpuspollenites retipilatus, Myrtaceidites spp., Ctenolophonidites costatus, Polygalacidites spp. demonstrate excellent preservation and clear morphological features as observed in modern ones. This method has provided a new dimension to study the palynofloral diversity and other ecological associations of the amber produced in tropical rainforest ecosystem in low latitude during the early Paleogene warming.
Mid to late Quaternary Fluvial activity in allochthonous river systems of the Maharashtra Plateau, India: A review and new observations
Authors: S. Kale Vishwas
Published: September 2022

The Maharashtra Plateau dominantly displays an erosional landscape and the Quaternary alluvial deposits in the valleys are remarkably limited in areal extent and thickness. The only exceptions are the infilled basins/valleys downstream of bedrock gorges with knickpoints. Earlier studies have inferred a good correspondence between the major changes in the monsoon regime and the fluvial activity (aggradation and incision/excavation) on the regional–scale during the last approx. 103 –105 years. However, geomorphic evidence suggests that some of the mid to late Quaternary aggradational events may not be directly related to known climatic events and the fluvial activity in some of the tributaries did not correspond with the recognized regional behavioural pattern. Basin–specific tectonic activity as well as alterations in the isohyetal pattern in the rainshadow zone appear to be the plausible reasons for the observed variations in the fluvial responses. The relationship between Quaternary climate changes and the fluvial activity, even in this area of uniform lithology, appears to be a complex one.
A river flowing through a desert: late Quaternary environments in the Nile basin – current understanding and unresolved questions
Authors: Williams Martin A.J.
Published: September 2022

Late Quaternary environments in the Nile Basin reflect the influence of the African summer monsoon upon plant cover, sediment yield and flood discharge in the Ethiopian and Ugandan headwaters of the Nile. Intervals of prolonged and very high Nile flow coincide with times of stronger summer monsoon and have been dated using a combination of 14C, OSL and 10Be methods. Periods of high Nile flow into the eastern Mediterranean coincide with the formation of highly organic sedimentary layers termed sapropels. Ages obtained so far for these times of sustained middle to late Pleistocene high flow in the Blue and White Nile are broadly coeval with sapropel beds S8 (ca 217 ka), S7 (ca 195 ka), S6 (ca 172 ka), S5 (ca 124 ka), S4 (ca 102 ka) S3 (ca 81 ka), S2 (ca 55–50 ka) and S1 (10–6.5 ka). Sapropel 5 (ca 124 ka) was synchronous with extreme Blue Nile floods and the formation of the 386 m lake in the lower White Nile Valley, as well as with a prolonged wet phase in the eastern Sahara. Fluctuations in Nile flow and sapropel formation reflect the influence of the precessional cycle upon the East African monsoon.
Between 75 ka and 19 ka the climate in the Nile headwaters region became progressively colder and drier. During the Last Glacial Maximum, Lake Tana in Ethiopia and Lake Victoria in Uganda became dry, flow in the White Nile was reduced to a trickle, and the Blue Nile and Atbara became highly seasonal bed–load rivers. The return of the summer monsoon at 14.5 ka ushered in extreme Blue Nile floods, widespread flooding across the Nile Basin and the formation of the 382 m lake in the lower White Nile Valley. There was a brief return to aridity during the Younger Dryas (12.8–11.5 ka), after which the climate again became wetter and widespread flooding in the Nile Valley resumed. The early Holocene floods were later followed by incision and creation of the modern relatively narrow flood plain.

Published: September 2022

Individual identities can be shaped not only offline but also online, according to studies. However, students' online identities in higher education institutions are complicated. Academics are interested in using social media to improve their professional identity and reputation, according to empirical research. The current research looked at the impact of online social capital and social networking on graduate students' professional identity formation. The research hypotheses were tested using structural equation modelling. A total of 298 graduate students from one of Iran's top public universities and three private higher education institutions were included in the study. The findings revealed that using online social capital as a mediator, online social networks in higher education environments can influence the creation of students' professional identities. The purpose of this study is to see how social networking affects college students. The research incorporates a variety of approaches to reach this goal, including descriptive/interpretive literature reviews and earlier studies conducted by academics and industrial institutions. It also makes use of polls conducted among university students. In order to investigate the impact of social networking on college students, a questionnaire was issued to 179 students from various universities and higher education institutes around the Sultanate of Oman.
escritos del arzobispo de Santiago, de fray Pedro de la madre de Dios y el papel titulado “Justa cosa justa cosa ha sido eligir por patrona de España y admitir por tal a Santa Teresa”, en el “Memorial por el patronato de Santiago” de Quevedo
Authors: Candelas Colodrón Manuel Ángel
Published: September 2022

Diversos estudiosos, historiadores y biógrafos han publicado investigaciones sobre la intervención de Francisco de Quevedo en la disputa del nombramiento de Santa Teresa como copatrona de España en el siglo XVII. El poeta escribió un memorial y una obra, ambos sobre la figura de Santiago de Compostela, y en este artículo se relacionan con el contexto de la época y la acogida por parte del público elevado de esos dos escritos, ya que suscitaron polémica. Por ello, también se menciona el Memorial de Tamayo de Vargas y se incluyen otros documentos, como cartas, de Felipe IV, el arzobispo de Santiago, el obispo de Córdoba y Fray Pedro de la madre de Dios, involucrados en este asunto, sin cuyas palabras no se entenderían las publicaciones quevedianas.
Sobre héroes, tumbas y reyes: Cardeña, 1512 y la publicación de la Crónica Particular
Authors: Martín Óscar
Published: September 2022

La Crónica Particular del Cid, publicada en Burgos en 1512 por Juan de Velorado, el abad de San Pedro de Cardeña, por orden del infante don Fernando, no ha recibido atención crítica hasta hace poco. En artículos recientes se ha apuntado que la publicación de esta crónica se explica dentro de una reacción comercial a la publicación en Sevilla en 1498 de la Crónica Popular. Si bien esta reacción comercial está detrás de la publicación de la Crónica Particular, este artículo profundiza en las causas que llevaron a la impresión de la misma mediante un análisis de las condiciones políticas y económicas que rodearon su publicación. Muestra cómo la Crónica Particular no sólo intenta promover las posibilidades sucesorias del infante Fernando mediante el énfasis en el linaje castellano del Cid, que se convierte en la base de la legitimación histórica de la monarquía, sino también cómo la crónica adecenta la visión del Cid para autorizar a Cardeña como centro oficial cidiano, purgardo la tradición precedente de aspectos negativos del Cid como la violencia y la bastardía.

La nueva novela histórica escrita desde los cálculos del positivismo de fines de siglo XIX se proyecta como un análisis objetivo de la sociedad que además da razón a una perspectiva historicista sobre la misma. Paz en la guerra de Miguel de Unamuno narra desde estas suposiciones las vidas de sus personajes en el marco de la última guerra carlista, el asedio de Bilbao y la oposición ideológica entre liberales y carlistas. Desde el punto de vista del historicismo positivista y liberal de la obra se tienen presentes estos acontecimientos para hacer inteligible la actualidad histórica desde la que se escribe, en particular el problema de la Restauración. Pero frente a las habituales normas artísticas del realismo y naturalismo mediante las cuales se narran los hechos incide en la obra el idealismo hegeliano como un enfoque alternativo para así producir una conclusión verdaderamente insólita a esta novela histórica.
Discurso político, tejido estético y autoficción fantástica en Lumpérica, de Diamela Eltit
Authors: López de Abiada José Manuel
Published: September 2022

Lumpérica (1983), primera novela de la narradora chilena Diamela Eltit (1949), consagra a la autora cual figura destacada de la narrativa iberoamericana de la década de los ochenta. Entre los valores de la novela figura su función de obra pionera y adelantada de un nutrido corpus novelesco, pero acaso su principal característica es que la escritura desbordaba con creces las estrechas lindes de la literatura de oposición al régimen dictatorial, marcada y condicionada por la rigidez estética y una poética testimonial gastada y anacrónica. Seguro es además que los conceptos del modelo genettiano no ―alcanzan‖ para definir los vínculos y el compromiso entre la autora y la historia narrada, que se mueve en los aledaños de lo autobiográfico, aunque sin respetar las formas de género, por lo que para poder referirse a los ―niveles‖ de presencia de la autora, habrá que acuñar un término nuevo (homobiográfico, p. ej.) o recurrir a un marbete reciente que Alberca llama autobioficción fantástica.
autógrafo de la carta de Gustavo Adolfo Bécquer a Juan José Bueno y otras epístolas relativas a su familia
Authors: Palenque Marta
Published: September 2022

El 18 de octubre de 1854 Gustavo Adolfo Bécquer escribía desde Madrid una carta al poeta y bibliófilo sevillano Juan José Bueno en la que le solicitaba el envío de algunas recomendaciones que le facilitasen conseguir un empleo en la capital. El texto completo de esta epístola ha pasado casi desapercibido en la bibliografía sobre el autor y no ha sido recogido entre sus obras completas. En este artículo reproduzco el manuscrito original y comento su particular transmisión. Asimismo valoro su contenido con respecto a la cronología becqueriana y a la formación literaria del poeta. Copio, además, dos cartas manuscritas e inéditas de José y Joaquín Domínguez Bécquer.

Esta reseña comenta las dos primeras series de los Episodios Nacionales galdosianos de una edición de Destino compuesta por cinco series en total; cada libro contiene diez episodios nacionales.

Para estos volúmenes se han tenido en cuenta las versiones de Galdós y se incluyen en el Apéndice algunos fragmentos que él mismo desechó. Esta edición es una reconstrucción de otras anteriores para mejorar en calidad y cantidad las novelas, que vienen precedidas por un contexto histórico y una bibliografía.

Published: September 2022

Uno de los elementos clave del libro de Carmen Becerra que aquí se reseña es el trasvase de un arte a otro; en este caso, del teatro al cine, y su posterior influencia mutua, además del carácter narrativo del cine. En el libro se señalan las diferencias que existen en cada arte; cada apartado, escrito por un estudioso distinto, analiza varias cuestiones: relaciones entre teatro y cine; el teatro y las nuevas tecnologías; conexiones entre los diferentes géneros teatrales y cinematográficos; historia del teatro y la censura; comparaciones entre adaptaciones dramáticas y cinematográficas de la misma obra…
Florinda perdió su flor. La leyenda de La Cava, el teatro neoclásico español y la tragedia Florinda de Mª Rosa Gálvez de Cabrera.
Authors: Establier Pérez Helena
Published: September 2022

Ya desde la misma Edad Media, la historiografía y la literatura españolas se hicieron eco de la leyenda que circulaba, tanto en la España cristiana como en la musulmana, en torno al trágico final del último reino godo, vinculando la catástrofe de Guadalete con el estupro de Florinda La Cava por el rey Rodrigo, y con la implacable venganza del padre de aquella, el conde Don Julián. Hasta el siglo XIX, el personaje de Florinda fue llevado en diversas ocasiones a la literatura y en particular a la escena, que había encontrado en la culpabilidad de 'la Cava' un incomparable instrumento ideológico para justificar las sombras que empañaban la etapa fundacional de la nación española. En 1804, la poeta y dramaturga María Rosa Gálvez publica su tragedia Florinda, donde proporciona al personaje una nueva carga simbólica y, ofreciendo una contralectura del mito, permite nuevas interpretaciones acordes con el género de su autora y con la España, perromántica y preliberal, en que se gesta la obra.
Ganivet y Zorrilla: huellas de Don Juan Tenorio en El escultor de su alma
Authors: De la Fuente Ballesteros Ricardo
Published: September 2022

Este trabajo repasa la lectura que hace Ganivet de Zorrilla y en particular las huellas que el Don Juan Tenorio ha dejado en el insólito auto del escritor granadino: El escultor de su alma. De las intertextualidades se pasa a realizar una interpretación de este texto dramático, incidiendo en la importancia del rechazo de la materia, la hipóstasis de la pureza, la exaltación de la Inmaculada, el significado de la petrificación y la muerte liberadora.
cuento en el cambio de siglo: del ideal reformista al desencanto
Authors: Casas Ana
Published: September 2022

El presente trabajo estudia las manifestaciones del cuento del Fin de Siglo que conectan con el denominado por la crítica espíritu del 98. Dentro del contexto socio-político del (fracasado) sistema de la Restauración, el cuento regeneracionista tiene como centro el problema de España y la búsqueda de soluciones que remedien los males nacionales (la corrupción política y el caciquismo, así como determinados "valores" muy extendidos en la sociedad del momento, entre ellos la hipocresía, la doble moral y la infravaloración del trabajo). En algunos casos, el pensamiento utópico (sobre todo el socialismo y el anarquismo) aporta a esta clase de cuentos que tienen un fin reformista determinadas temáticas y motivos, entre ellos la falta de caridad y la indiferencia social, la figura del delincuente, la defensa de la libertad individual y la condena de las instituciones.
