REINSTATEMENT OF ALOE SPECTABILIS
Pollen and reproductive morphology of Rhigiophyllum and Siphocodo (Campanulaceae): two unique genera of the fynbos vegetation of South Africa
Authors: Eddie W. M. M. , Cupido C. N. , Skvarla J. J.
Published: July 2015

Pollen grains of Rhigiophyllum squarrosum Hochst., Siphocodon spartioides Turcz. and S. debilis Schltr., are flattened and triangular with pores at the angles. This morphology is radically different from known pollen of the Campanulaceae s.sfr:: the Campanulaceae are treated here as a family separate from the Lobeliaceae, Cyphiaceae, Nemacladaceae, Pentaphragmataceae and Sphenocleaceae (Lammers 1992). As traditionally conceived, the Campanulaceae is very heterogeneous and, in many classifications, these families were treated as subfamilies of a much-enlarged Campanulaceae. The consistently different floral morphology, biochemistry and pollen structure of the Lobeliaceae favours the recognition of this predominantly tropical group as a separate family.The pollen grains of these species are described in comparison with other members of the Campanulaceae. Based on surface characteristics of their pollen grains, we conclude that they represent an early offshoot o f the wahlenbergioid line­age in southern Africa. We suggest that this unique pollen may also be the result of a highly selective regime in the fynbos, associated with specialized pollinators, and base-poor soils, in addition to possible adaptations for ant dispersal and fire. Rhigiophyllum Hochst. and Siphocodon Turcz. are also unique in having free carpel-like structures within the ovary. These shrink to form seed pockets around the seeds and disperse as units when the capsule matures. Data from molecular studies support the contention that these taxa form a sister group to all other wahlenbergioids and that this should be formally recognized in a classification system. We treat Rhigiophyllum and Siphocodon within the Campanulaceae: Wahlenbergioideae, as a separate tribe, the Rhigiophylleae tribus nov., the species of which are distinguishable from other wahlenbergioids by unique angulaperturatc pollen, epipetalous stamens, free carpel-like structures and seed pockets.

The rise of China and the time of Africa: Gauging Afro-Sino relations in the light of Confucian philosophy and African ideals
Authors: Du Toit Cornel
Published: July 2015

The article focuses on Sino-African relations, with specific reference to South Africa. An outline is provided of recent developments as a roadmap for the unfolding of this relationship. The question of whether China’s African interest can be seen as tacit colonisation is discussed. Even if these fears are allayed, the question remains whether the Chinese presence on the continent will make a significant difference to African development. To answer this question, the focus shifts to economic models and the Chinese recipe for economic progress. Confucianism was opposed during the cultural revolution of Mao Zedong, but it now forms the basis for Chinese foreign policy and internal affairs. This is briefly investigated. Some Confucian ideas are related to basic African concepts in an effort to find a common ground in Afro-Chinese relations. The impact of secular Confucianism on African spirituality is discussed.
Streef na vrede met almal? Hebreërs 12:14 in perspektief
Authors: Coetsee Albert J.
Published: July 2015

Strive for peace with everyone? Hebrews 12:14 in perspective. What sounds like a simple exhortation in Hebrews 12:14 has caused a great deal of discussion amongst biblical scholars. Does the writer of Hebrews command his hearers to strive for peace with everyone everywhere, or is he exhorting them to strive for peace with all the members of their faith ommunity? Both interpretations have arguments for and against. The main arguments of both interpretations are the interpretation of the place of this exhortation in Hebrews, the meaning of the preposition μετά + genitive and the nuance of εἰρήνη within this context. This article tries to determine to whom the writer of Hebrews is referring with πάντων in 12:14 by doing thorough exegesis of this verse, and by so doing evaluating biblical scholar’s interpretation of πάντων. From this analysis certain implications are drawn for the first hearersand believers today.
Spiritual transformation: Reaching and equipping Sub-Saharan African children
Authors: Knoetze Johannes J.
Published: July 2015

Whenever a person engages with a child, the engagement is not neutral – it is ‘for better or for worse’. A fair question would be why Christians must reach and equip Africa’s children for spiritual transformation. By giving a missional perspective in an attempt to answer the question, this article wants to contribute to the development of an African child and youth theology. In the first part of the article, a specific understanding of theology and how it is practised, is described. Understanding and reaching children are put within a specifictheological and missiological understanding also of the local faith community. From a missiological perspective the second part of the article makes use of Christian anthropology to understand Africa’s children’s context and how the local faith community can equip them spiritually. The third part deals with the concept of spiritual transformation as a process, and the role of the local faith community within this process.Geestelike transformasie: Bereiking en toerusting van kinders in Sub-Sahara Afrika. Indien ’n persoon by ’n kind betrokke raak, is hierdie betrokkenheid nooit ’n neutrale gebeurtenis nie. Daarom is dit billik om te vra hoekom Christene na kinders in Afrika moet uitreik vir geestelike transformasie? In ’n poging om die vraag te beantwoord, verskaf die artikel ’n missiologiese perspektief in ’n poging om ’n bydrae tot die ontwikkeling van’n Afrika kinder- en jeugteologie te lewer. Die eerste gedeelte van die artikel beskryf die verstaan van teologie en hoe dit bedryf word. Die verstaan van, en uitreik na kinders in die Afrikakonteks, asook die plaaslike geloofsgemeenskap word binne hierdie spesifieke missionale teologiese verstaan beskryf. In die tweede gedeelte van die artikel word daar vanuit die missiologiese perspektief gebruik gemaak van ’n Christelike antropologiese perspektief om die konteks van Afrikakinders te verstaan, asook die manier van geestelike toerusting deur die plaaslike geloofsgemeenskap. Die derde gedeelte van die artikel bespreek geestelike transformasie as ’n proses, asook die rol van die plaaslike geloofsgemeenskap in hierdie proses.
Computing the Smallest Eigenvalue of Large Ill-Conditioned Hankel Matrices
Authors: Emmart Niall , Chen Yang , Weems Charles C.
Published: July 2015

This paper presents a parallel algorithm for finding the smallest eigenvalue of a family of Hankel matrices that are ill-conditioned. Such matrices arise in random matrix theory and require the use of extremely high precision arithmetic. Surprisingly, we find that a group of commonly-used approaches that are designed for high efficiency are actually less efficient than a direct approach for this class of matrices. We then develop a parallel implementation of the algorithm that takes into account the unusually high cost of individual arithmetic operations. Our approach combines message passing and shared memory, achieving near-perfect scalability and high tolerance for network latency. We are thus able to find solutions for much larger matrices than previously possible, with the potential for extending this work to systems with greater levels of parallelism. The contributions of this work are in three areas: determination that a direct algorithm based on the secant method is more effective when extreme fixed-point precision is required than are the algorithms more typically used in parallel floating-point computations; the particular mix of optimizations required for extreme precision large matrix operations on a modern multi-core cluster, and the numerical results themselves.

Evaluating Approaches to Teaching and Learning Chinese Vocabulary from the Learning Theories Perspective: An Experimental Case Study
Authors: SIMONČIČ Katja
Published: July 2015

With Chinese language gaining more and more popularity among Slovenian students and with the growing numbers of learners of Chinese as a foreign language in Slovenia and elsewhere it is crucial to find an approach that will lead to high quality and long-term knowledge of Chinese and that will motivate learners to continue learning.We can speak of two basic approaches to teaching Chinese vocabulary: the approach that first introduces pronunciation and the approach that simultaneously introduces pronunciation and character. The key question that arises is which of the two approaches leads to high quality and long-term knowledge? To answer the question an experimental case study was carried out at Ljubljana’s Faculty of Arts in the academic year 2011/2012. The case study showed that the approach that simultaneously introduces pronunciation and character and is based on the key principles of constructivist learning theory had beneficial effects on the students in terms of motivation and quality of knowledge of Chinese vocabulary.
Which Second Language Learning Theories Underlie Language Courses Offered by Slovene Private Language Schools
Authors: Meznarič Marša
Published: July 2015

The article deals with language courses offered by private language schools in Slovenia. It examines who the people in charge of the language schools are, what criteria new teachers have to meet to become an employee of a school, whether the methodology applied (if any) has been carefully chosen, what the teaching techniques are and who chooses them.Second language method discoveries have been subjected to perennial criticism and scepticism over the last half of century. Teachers around the globe have been confused by the constant shifts in the popularity of different methods. The article examines the con sequences of the abovementioned circumstances.The 15 interviews conducted with private language schools’ managers have generated valuable information on the level of professionalism in this area of business.The results have shown that most of the randomly chosen schools are managed by language professionals or by economists who employ a linguist for controlling the teaching and learning processes and that the majority of schools does adopt a particular approach or method of teaching. Teacher trainees receive a lot of support and guidance prior to teaching in a school. In most cases, teachers are free to choose techniques of teaching according to their preferences, providing the techniques are not in conflict with the general schools’ principles. The criteria for employment vary considerably. Nearly all managers would employ a professional language teacher with experience only, but others demand that the teacher be a native speaker regardless of his/her education. Several stress the importance of personal characteristics and would consider employing only lighthearted and energetic teachers. Teachers’ work and students’ progress are often evaluated.

Popravljanje in odpravljanje napak v procesu usvajanja tujega jezika
Authors: Žugelj Nataša
Published: July 2015

Pričujoči članek obravnava odnos učiteljev in jezikoslovcev do napak učencev v procesu usvajanja tujega jezika. V zadnjem času se je odklonilni odnos spremenil, podrobna analiza napak in njihovo razvrščanje pa sta privedla do tega, da so napake postale dragocen pripomoček za delo v razredu. Ta novi pristop do napak spodbuja učence k razmisleku o njihovih napakah in o delovanju jezikovnega sistema, ki ga želijo usvojiti. Učitelj, ki si prizadeva izboljšati jezikovno kompetenco svojih učencev, mora imeti široko teoretično znanje in dobro mero potrpežljivosti, predvsem pa mora znati izbrati najugodnejši trenutek in najboljši način za obravnavanje določene napake. To slednje je dolg proces, ki zahteva dejavno sodelovanje tako s strani učitelja kot učenca.
Philosophy, Sophistry, Antiphilosophy
Authors: McLennan Matthew R.
Published: July 2015

Alain Badiou's work in philosophy, though daunting, has gained a receptive and steadily growing Anglophone readership. What is not well known is the extent to which Badiou's positions, vis-à-vis ontology, ethics, politics and the very meaning of philosophy, were hammered out in dispute with the late Jean-François Lyotard. Matthew R. McLennan's Philosophy, Sophistry, Antiphilosophy is the first work to pose the question of the relation between Lyotard and Badiou, and in so doing constitutes a significant intervention in the field of contemporary European philosophy by revisiting one of its most influential and controversial forefathers.

Badiou himself has underscored the importance of Lyotard for his own project; might the recent resurgence of interest in Lyotard be tied in some way to Badiou's comments? Or deeper still: might not Badiou's philosophical Platonism beg an encounter with philosophy's other, the figure of the sophist that Lyotard played so often and so ably? Posing pertinent questions and opening new discursive channels in the literature on these two major figures this book is of interest to those studying philosophy, rhetoric, literary theory, cultural and media studies.
Evidence of a prolonged drought ca. 4200 yr BP correlated with prehistoric settlement abandonment from the Gueldaman GLD1 Cave, N-Algeria

Abstract. Middle Holocene cultures have been widely studied round the E-Mediterranean basin in the last 30 years and past cultural activities have been commonly linked with regional climate changes. However, in many cases such linkage is equivocal, in part due to existing climatic evidence that has been derived from areas outside the distribution of ancient settlements, leading to uncertainty from complex spatial heterogeneity in both climate and demography. A few high-resolution well-dated paleoclimate records were recently established using speleothems in the Central and E-Mediterranean basin, however, the scarcity of such records in the western part of the Mediterranean prevents us from correlating past climate evolutions across the basin and deciphering climate–culture relation at fine time scales. Here we report the first decadal-resolved Mid-Holocene climate proxy records from the W-Mediterranean basin based on the stable carbon and oxygen isotopes analyses of two U/Th dated stalagmites from the Gueldaman GLD1 Cave in N-Algeria. Comparison of our records with those from Italy and Israel reveals synchronous (multi) centennial dry phases centered at ca. 5600, ca. 5200 and ca. 4200 yr BP across the Mediterranean basin. New calibrated radiocarbon dating constrains reasonably well the age of rich anthropogenic deposits (e.g., faunal remains, pottery, charcoal) excavated inside the cave, which allows the comparison between in situ evidence of human occupation and of climate change. This approach shows that the timing of a prolonged drought at ca. 4400–3800 yr BP blankets the onset of cave abandonment shortly after ca. 4403 cal yr BP, supporting the hypothesis that a climate anomaly may have played a role in this cultural disruption.
A soil diffusion-reaction model for surface COS flux: COSSM v1
Authors: Sun W. , Maseyk K. , Lett C. , Seibt U.
Published: July 2015

Abstract. Soil exchange of carbonyl sulfide (COS) is the second largest COS flux in terrestrial ecosystems. A novel application of COS is the separation of gross primary productivity (GPP) from concomitant respiration. This method requires that soil COS exchange is relatively small and can be well quantified. Existing models for soil COS flux have incorporated empirical temperature and moisture functions derived from laboratory experiments, but not explicitly resolved diffusion in the soil column. We developed a 1-D diffusion-reaction model for soil COS exchange that accounts for COS uptake and production, relates source-sink terms to environmental variables, and has an option to enable surface litter layers. We evaluated the model with field data from a wheat field (Southern Great Plains (SGP), OK, USA) and an oak woodland (Stunt Ranch Reserve, CA, USA). The model was able to reproduce all observed features of soil COS exchange such as diurnal variations and sink-source transitions. We found that soil COS uptake is strongly diffusion controlled, and limited by low COS concentrations in the soil if there is COS uptake in the litter layer. The model provides novel insights into the balance between soil COS uptake and production: a higher COS production capacity was required despite lower COS emissions during the growing season compared to the post-senescence period at SGP, and unchanged COS uptake capacity despite the dominant role of COS emissions after senescence. Once there is a database of soil COS parameters for key biomes, we expect the model will also be useful to simulate soil COS exchange at regional to global scales.
Temperature and rainfall estimates for past 18 000 years in Owens Valley, California with a coupled catchment–lake model
Authors: Yu Z. , Dong W. , Jiang P.
Published: July 2015

Abstract. Closed-basin lakes are intricately linked to the hydrological systems and are very sensitive recorders of local hydro-climatic fluctuations. Lake records in closed-basins are usually used to investigate the paleoclimate condition which is critical for understanding the past and predicting the future. In this study, a physically based catchment–lake model was developed to extract quantitative paleoclimate information including temperature and rainfall over the past 18 000 years (ka) from lake records in a hydrologically closed basin in the Owens River Valley, California, US. The initial model inputs were prepared based on current regional climate data, boundary conditions from the General Circulation Model, and fossil proxy data. The inputs subsequently were systematically varied in order to produce the observed lake levels. In this way, a large number of possible paleoclimatic combinations can quickly narrow the possible range of paleoclimatic combinations that could have produced the paleolake level and extension. Finally, a quantitative time-series of paleoclimate information for those key times was obtained.
Influence of natural surfactants on short wind waves in the coastal Peruvian waters
Authors: Kiefhaber D. , Zappa C. J. , Jähne B.
Published: July 2015

Abstract. Results from measurements of wave slope statistics during the R/V Meteor M91 cruise in the coastal upwelling regions off the coast of Peru are reported. Wave slope probability distributions were measured with an instrument based on the reflection of light at the water surface and a method very similar to the Cox and Munk (1954b) sun glitter technique. During the cruise, the mean square slope (mss) of the waves was found to be very variable, despite the limited range of encountered wind speeds. The Cox and Munk (1954b) parameterization for clean water is found to overestimate mss, but most measurements fall in the range spanned by their clean water and slick parameterizations. The observed variability of mss is attributed to the wave damping effect of surface films, generated by increased biological production in the upwelling zones. The small footprint and high temporal resolution of the measurement allows for tracking abrupt changes in conditions caused by the often patchy structure of the surface films.

Image Analysis: Textile Industry in Indonesia
Authors: S. H. Hengky
Published: July 2015

In 2014, the Indonesian textile industry exports 36% of their woven fabric's amount USD 4.1 to the United States, 16% to the European Union and Japan, and 5% to the Association of Southeast Asian Nations (ASEAN). This research was conducted from August 2014 to April 2015 in Indonesia. The questionnaires were distributed to 350 respondents, by using a stratified sampling, purposively, and triangulation techniques. The questionnaires were distributed to an international and national distributors, textile company staffs, textile agency, textile shopkeepers, tailor, staff of the garment, and the staffs of the Trade Minister of Indonesian. The image analysis shows that the woven fabrics of Indonesia are competitive. In terms of an image analysis, this study found three gaps of the image’s expectation and performance. It is indicated that the plan of the Trade Minister of Indonesia would be done, as long as the plan is followed by increasing the production and finishing capacity of the textile industry, which were imported from several countries, such as Germany, Italy, and ASEAN country. They need the new technology of textile machine on getting a better quality and increasing the production capacity of the woven fabrics.
Nontuberculous mycobacterial infection presenting as empyema and life threatening pneumothorax: A challenging situation in the emergency department
Authors: Anjum Shahzad , Tahir Ramsha , Pathan Sameer A.
Published: July 2015

Nontuberculous mycobacterial infection in an immunocompetent young patient complicated with empyema and pneumothorax is rarely reported. A 36-year-old man presented to the emergency department with a history of worsening dyspnea and pleuritic chest pain. The patient had unstable vital signs on presentation, and was referred to the resuscitation area on a monitored bed. The patient had a chest x-ray (CXR) performed on a prior occasion at a primary health clinic, revealing pneumothorax and some fluid at the left costophrenic angle. On arrival at the hospital, bedside ultrasound was performed which confirmed the diagnosis of pneumothorax. His vital signs were pulse 153, BP 88/62, RR 50 breaths per minute and his oxygen saturation on air was 92%. Tension pneumothorax was diagnosed based on clinical presentation and given vital signs. It was managed immediately with needle decompression followed by chest tube insertion. The patient improved dramatically after needle decompression with stabilization of vital signs. A CXR was repeated post-needle decompression which showed an incompletely resolved pneumothorax with an increase in the size of the effusion. Iatrogenic haemothorax was a possible explanation for this increase in effusion size. Chest tube was successfully inserted in the fourth intercostal space just anterior to the midaxillary line under full aseptic precautions. The chest tube drained 1.4 liters of blood, which on analysis showed a low pH and elevated adenosine deaminase level. Two out of three sputum samples sent from the medical ward were positive for mycobacteria other than tuberculosis as confirmed on culture. The patient's symptoms improved with percutaneous tube drainage of hemopneumothorax and antituberculous medications.
Are hermaphrodites better adapted to the colonization process in trioecious populations of Salix myrsinifolia?
Authors: Mirski Paweł , Brzosko Emilia
Published: July 2015

In trioecious plant populations, the role of hermaphroditism is often uncertain. We investigated the advantages of hermaphroditism in the dioecious shrub Salix myrsinifolia. The sex ratio of 30 S. myrsinifolia populations in northeastern Poland (secondary range) and Lithuania (primary range) was investigated in 2010–2011. Measures of reproductive (number of catkins, number of flowers in catkins) and vegetative traits (height, diameter, number of shoots, vitality) were taken and compared among sexual morphs. In two populations, measurements collected 14 years prior on marked individuals were used to determine the rate of changes in height, crown diameter and survivorship rates. We found trioecy mostly in the secondary part of the range with an average share of hermaphrodites reaching 21% in the trioecious populations. The sex ratio varied between populations, but tended mostly towards female domination. Several traits differed significantly among sexes. The characteristics of hermaphrodites were often intermediate between males and females and provided no evidence for the higher competitive abilities of hermaphrodites. We concluded that the possible gain of hermaphroditism in the colonization process is restricted to reproduction. We consider hermaphroditism in S. myrsinifolia as an equilibrium between the allocation of resources for growth and reproduction in unstable conditions on the margins of the range.

Published: July 2015

Despite long-term research, the aquatic genus Nymphaea still possesses major taxonomic challenges. High phenotypic plasticity and possible interspecific hybridization often make it impossible to identify individual specimens. The main aim of this study was to assess phenotypic variation in Nymphaea taxa sampled over a wide area of Eastern Europe and temperate Asia. Samples were identified based on species-specific genome sizes and diagnostic morphological characters for each taxon were then selected. A total of 353 specimens from 32 populations in Poland, Russia and Ukraine were studied, with nine biometric traits being examined. Although some specimens morphologically matched N. ×borealis (a hybrid between N. alba and N. candida) according to published determination keys, only one hybrid individual was revealed based on genome size data. Other specimens with intermediate morphology possessed genome size corresponding to N. alba, N. candida or N. tetragona. This indicates that natural hybridization between N. alba and N. candida is not as frequent as previously suggested. Our results also revealed a considerably higher variation in the studied morphological traits (especially the quantitative ones) in N. alba and N. candida than reported in the literature. A determination key for the investigated Nymphaea species is provided, based on taxonomically-informative morphological characters identified in our study.
Does vegetation impact on the population dynamics and male function in Anemone sylvestris L. (Ranunculaceae)? A case study in three natural populations of xerothermic grasslands
Authors: Denisow Bożena , Wrzesień Małgorzata
Published: July 2015

In Poland, like in other parts of Central Europe, dry grasslands significantly contribute to the biodiversity of both fauna and flora. Anthropogenic pressure impair many species of xerothermic habitats, and several populations face an increased risk of extinction. The goal of the study was to define factors that may affect the size of wild populations of Anemone sylvestris L., a protected species in Poland, with both a short- and long-term perspective, and to examine the influence of vegetation changes on the density, the abundance of flowering and male function (pollen production, pollen viability), as well as seed set. In situ observations were performed in 2005–2006 and 2011–2012 in three populations located on the Lublin Upland, SE Poland. The reduction in population density and A. sylvestris blooming was exacerbated by the expansion of the shrubs, but not by Brachypodium pinnatum. Male characteristics of A. sylvestris, i.e. pollen amount per multi-staminate flowers or pollen viability appeared to decrease under pressure of shrub competition. Populations with limitation of male function had impaired degree of seed set. Various consequences for the functioning of populations within a metapopulation system can be expected due to substantial qualitative and quantitative disorders in pollen traits. It is crucial that successful recovery programs for A. sylvestris primary should aim to conserve and manage the habitat.
Changes in vegetation and soil seed bank of meadow after waterlogging caused by Castor fiber
Authors: Franczak Magdalena , Czarnecka Bożenna
Published: July 2015

Soil waterlogging is among abiotic stresses that influence species composition and productivity in numerous plant communities. The aim of the study was to find answer to the question of how waterlogging caused by beavers’ activity induces quantitative and qualitative changes of vegetation and soil seed bank levels of variable-moist meadows.

An immediate effect of the waterlogging at the level of vegetation was the decline in species richness and a decrease in the values of the biodiversity index. Water stress inhibited growth and development of plants already present and, primarily, impeded recruitment of new individuals of species characteristic of variable-moist meadows, e.g. Cirsium rivulare, Filipendula ulmaria and Lythrum salicaria, which were replaced by Carex acutiformis. Prolonged waterlogging did not induce equally substantial changes in the soil seed bank as in the vegetation. Both in the waterlogged and control patches, slightly decreased species richness and biodiversity index were recorded. After waterlogging withdrawal, the reserves of the soil seed bank were slightly higher than the initial values. The differences were not statistically significant.

In the waterlogged patch, the qualitative floristic similarity between taxa identified in the soil seed bank and vegetation cover declined, which was evidenced by the value of Jaccard’s index decreasing from 0.46 to 0.36. A reverse relationship was found in control patch, where the value of the similarity index slightly increased from 0.41 to 0.48.
The Glaucophyta: the blue-green plants in a nutshell
Authors: Jackson Christopher , Clayden Susan , Reyes-Prieto Adrian
Published: July 2015

The Glaucophyta is one of the three major lineages of photosynthetic eukaryotes, together with viridiplants and red algae, united in the presumed monophyletic supergroup Archaeplastida. Glaucophytes constitute a key algal lineage to investigate both the origin of primary plastids and the evolution of algae and plants. Glaucophyte plastids possess exceptional characteristics retained from their cyanobacterial ancestor: phycobilisome antennas, a vestigial peptidoglycan wall, and carboxysome-like bodies. These latter two traits are unique among the Archaeplastida and have been suggested as evidence that the glaucophytes diverged earliest during the diversification of this supergroup. Our knowledge of glaucophytes is limited compared to viridiplants and red algae, and this has restricted our capacity to untangle the early evolution of the Archaeplastida. However, in recent years novel genomic and functional data are increasing our understanding of glaucophyte biology. Diverse comparative studies using information from the nuclear genome of Cyanophora paradoxa and recent transcriptomic data from other glaucophyte species provide support for the common origin of Archaeplastida. Molecular and ultrastructural studies have revealed previously unrecognized diversity in the genera Cyanophora and Glaucocystis. Overall, a series of recent findings are modifying our perspective of glaucophyte diversity and providing fresh approaches to investigate the basic biology of this rare algal group in detail.
Aberrant phyllotactic patterns in cones of some conifers: a quantitative study
Authors: Fierz Veronika
Published: July 2015

The scale patterns of 6000 cones from one single tree of Pinus nigra Arn. have been examined. Apart from the main Fibonacci pattern with 8 and 13 parastichies, nine aberrant spiral patterns with Fibonacci-type sequences have been found. They are quite rare and occur with different frequencies. The parastichy quotient 8/13 of the prevalent pattern is very close to the golden ratio 0.618. In case of the black pine  it appeared that the greater the deviation of the parastichy quotient m/n from 0.618, the rarer the pattern. Similar results obtained for the sample of 1506 cones collected from three individual trees of larch (Larix decidua Mill.) suggest a true correlation between the frequency of a pattern and the deviation of its parastichy quotient from the golden ratio.
