Vocalizations of Unicolored Jays (Aphelocoma unicolor) at Montebello, Chiapas, Mexico
Authors: Webber Tom , Stotz Nancy G.
Published: February 2024

Unicolored Jays (Aphelocoma unicolor) are little-known social corvids of Mexico and Middle America. Like other birds in the family Corvidae they possess a vocabulary composed of sounds usually referred to as calls rather than songs. Here we provide the first description of this species’ rich vocabulary. We studied vocalizations of color-banded Unicolored Jays in Chiapas, Mexico from January through May of 1987. There they live in cooperatively breeding groups of four to nine birds. We distinguish 697 long-range call variants from our recordings, which probably did not exhaustively sample the range of jay sounds on our study site. The sonograms of the sounds can divided into broad categories with finely graded spectrum-like variation within them, and generally no sharp boundaries between them. Nearly any sonogram in the vocabulary can be connected structurally to any other through a range of intermediates. The jays tended to introduce many new related variations on a call theme in a single calling session, and many of these variants were not recorded again. There is some indication that the jays favored using a few call types in particular behavior contexts, but they used the great majority of them in a range of widely varying settings. The jay groups shared only a minority of their call collections with one another, but many of the unshared calls were rarely recorded and may not have represented typical vocal differences between them. A few commonly used calls did seem to be peculiar to one or a few jay groups. Vocalizations recorded on our study site in 1987 differ notably from those recorded there in 2006, strongly suggesting cultural turnover in the local assortment of calls. Recordings from other A. unicolor populations in southern Mexico show marked geographic variation on a regional scale. We suggest that the tendency of Unicolored Jays to produce series of similar and apparently new calls in spates, geographical variation in calls on scales small and large, and turnover in calls at a single locality may all reflect call learning, call improvisation, and the process of random vocal change known as culture drift. We also describe a variety of the jays’ soft short-range calls, some of them strikingly similar to those in other species of Aphelocoma, and others, including some common ones, not previously known in this genus. Like other Aphelocoma, A. unicolor on our study site had rattle calls (one fast and one slow), and whisper song. The precise similarities between certain calls of A. unicolor and those of its relatives show either a startling degree of fidelity in vocal copying over thousands of generations, or a strong innate tendency to reproduce certain details of their vocabularies.
Occurrence of the brachiopod Tichosina in deep-sea coral bottoms of the Caribbean Sea and its paleoenvironmental implications
Authors: Rojas Alexis , Gracia Adriana , Hernández-Ávila Ivan , Patarroyo Pedro , Kowalewski Michał
Published: February 2024

Despite its importance as the larger component of the modern and Cenozoic brachiopod faunas in the Caribbean region, the ecology and habitat preferences of the terebratulid Tichosina remain poorly understood. We compiled feld observations from multiple sites in the Caribbean of Colombia (i.e., San Bernado Bank, Bahia Honda-Guajira, Puerto Escondido, Joint Regime Area Jamaica-Colombia) and data from the R/V Pillsbury program, indicating that Tichosina may have close ecological ties with deep-water corals. In addition, we reviewed literature sources on Cenozoic sediments in the Dominican Republic and found tentative evidence that such ecological ties could have existed since at least the Pliocene. These observations are reminiscent of the Gryphus-anthozoan association observed along the modern Mediterranean continental margin. Understanding to what extent the brachiopod Tichosina is linked to deep-water habitats has implications for the recognition of deep-water macrobenthic communities in the Cenozoic rock record of the Caribbean.
Decapod crustaceans of the Seroe Domi Formation of Curaçao
Authors: Sload Ashleigh M. , Feldmann Rodney M. , Schweitzer Carrie E. , Portell Roger W. , Donovan Stephen K.
Published: February 2024

A new collection of brachyuran decapod crustaceans (crabs) from the Mio-Pliocene Seroe Domi Formation of Curaçao totals 284 specimens. They exhibit excellent preservation of fine details, including fragile spines and delicate surface textures; however, the majority of the specimens are fragmented and disarticulated. Seven genera are identified from six families; Raninidae, Calappidae, Aethridae, Leucosiidae, Mithracidae, and Portunidae. The decapod fauna from the Pliocene portion of the Seroe Domi Formation was compared to coeval Caribbean brachyuran faunas to judge the relative diversity. Jamaica hosts the largest concentration of Pliocene brachyurans in the Bowden Member of the Layton Formation. Other localities, in Costa Rica, Panama, Florida, and the Dominican Republic, were similar in generic diversity to that of the Seroe Domi Formation. Following uplift of the Central American Isthmus and the end of genetic exchange between the Pacific and Atlantic, crab species that previously spanned both oceans evolved into distinct Pacific and Atlantic forms. The Pliocene crabs of the Seroe Domi Formation all belong to species that represent Atlantic forms.
A middle Pleistocene bird community from Saint Lucie County, Florida
Authors: Kilmer John Andrew , Steadman David W.
Published: February 2024

Dickerson Coquina Pit (DCP) is a sand and coquina mine located in Saint Lucie County, Florida, 16 km inland from the Atlantic Ocean. Collections were made from a middle Pleistocene (late Irvingtonian Land Mammal Age) vertebrate fossil bed in the Okeechobee Formation at DCP from 2002 until the pit was flooded in 2008. Vertebrate fossils from DCP also were discovered in fill material used in beach replenishment on North Hutchinson Island, St. Lucie County. The avifauna of DCP is based on 65 fossil elements representing 12 orders, 16 families, and 26 species, with habitat preferences ranging from woodlands and prairies to fresh water and estuarine wetlands to the open ocean. Extinct or extralocal species include a transitional Wild Turkey Meleagris cf. M. gallopavo, transitional Short-tailed Albatross Phoebastria cf. P. albatrus, a large stork Ciconia maltha, a large crane Grus sp., Great Auk Pinguinus impennis, and Carolina Parakeet Conuropsis carolinensis. The taphonomy and paleoecology of the Dickerson Coquina Pit generally resemble those of other shell beds in Central and South Florida, such as the Irvingtonian Leisey Shell Pit of Hillsborough County. The avifauna from DCP is distinctive, however, in featuring Florida’s first Pleistocene records of four marine species (Short-tailed Albatross, Northern Gannet Morus bassanus, Great Cormorant Phalacrocorax carbo, and Great Auk) and the Carolina Parakeet.
Vertebrate paleontology at the Florida Museum of Natural History, University of Florida: the past 60 years of research and education
Authors: MacFadden Bruce J.
Published: February 2024

This paper presents the history and development of the vertebrate paleontology (VP) program since its inception at the Florida State Museum (name changed to Florida Museum of Natural History in 1988) over the past 60 years. Given the rich and ubiquitous 40-million-year fossil record exposed in Florida and general public interest in extinct life, it is not surprising that paleontology has continued to be a cornerstone of the museum. The impact of two aspects of this program is highlighted; i.e., (1) the “formative decade” from 1956 to 1965; and (2) the development of the VP collection and related activities over the past 60 years. VP has benefitted greatly from dedicated and passionate people involved in this program, including curators, staff, undergraduates, volunteers, and 80 graduate students. Other topics covered in this history include leadership, infrastructure, research, education, and outreach. Outcomes have included a collection that has grown to almost a half million digitized specimens, more than 15 million dollars of grant-supported projects, active, year-round field work, about 400 peer-reviewed papers published, and innovative exhibitions and public programs. The unique identity of the VP program and its recognition among peers both nationally and internationally results from the positive influences of these foundational core and related activities over the past 60 years.

Envisioning Posthuman India: An Analysis of S.B Divya’s Machinehood
Authors: Greeshma Johny
Published: February 2024

The contemporary technological epoch is witnessing the growth of posthuman discourse in science fiction novels as they focus on studying the future existence of humans and nonhumans. However, these posthuman insights and studies are mostly confined to Western sci-fi novels. The present study argues that contemporary Indian English science fiction optimistically deals with posthumanist concepts and shows how a harmonious existence is possible. The idea is delineated through S.B Divya’s debut novel Machinehood (2021), and it becomes a productive site to analyse posthuman India's future. The Borromean knot of human- achinenature in the novel delineates how this harmonious existence is possible. The study employs close reading and interpretation by using the concepts of “critical posthumanism” by Rosi Braidotti and “philosophical posthumanism” by Francesca Ferrando. The paper attempts to show how Divya deals with themes like advanced capitalism, neo-religion and sustainable environment, moving away from the conventional notions of anthropocentrism and how she unravels the potentials of posthumanism through symbiotic living.
Negotiating the Postmodern Narrative Techniques in Life of Pi
Authors: Sumita Kumari
Published: February 2024

The present paper attempts to analyse the complex and ambiguous phenomenon of the very movement of postmodernism in Yann Martel’s distinguished novel Life of Pi. Owing to the techniques and strategies employed in this novel, it can be called the true representative of postmodern fiction. As it breaks with realism and avoids rigid genre distinction, postmodernism deconstructs the wholeness and completeness associated with conventional storytelling ways. There is use of postmodern narrative as the novel is highly self-reflexive and Martel also experiments with intertextuality and historiographic metafiction. He weaves this novel withextraordinary and unusual events. By blending facts and fiction, he makes space for the readers for different interpretations. The contours of postmodern techniques such as fragmentation, metafiction, multiple points of view, advocacy of plurality of histories, and sheer rejection of grand narratives are used in this novel. Out here Martel delineates the chaotic condition of the postmodern world through Life of Pi.
Re-thinking Bodily Entrapment in Select Indian Trans Autobiographies
Authors: Preeti  , Dr. Shyamkiran Kaur
Published: February 2024

The present paper seeks to analyse two Indian trans autobiographies - The Truth About Me: A Hijra Life Story (2010) by A. Revathi, a distinguished trans activist; and Me Hijra, Me Laxmi (2015) by Laxmi Narayan Tripathi, a prominent Bharatnatyam dancer and trans activist. The autobiographical accounts critically explore the contribution of prevalent heteronormative ideologies to the marginalised status of transgender individuals in India. The narratives intricately depict the experiences of transgender individuals who grapple with a sense of mismatch between their assigned sex and psychological sex, ultimately leading them to undergo Sex Reassignment Surgery (SRS) and related medical procedures. Drawing upon the perspectives of post-transsexual scholars such as Jacques Juliet, Janice Raymond, Jay Prosser, Kate Bornstein, and Sandy Stone, the study asserts that the transgender body is "programmed to disappear," promotes a "denial of mixture," and perpetuates the "purity" of gender after the corporeal transition. Furthermore, the paper examines how trans individuals incorporate established medical discourse on transsexuality into their autobiographies. The research findings underscore the need to develop a transgender discourse capable of offering a counter-discourse to the binary explanations of gender.
Unravelling the Moral Development Stages of Sonya Kantor in Veronica Roth’s Poster Girl through Kohlberg’s Moral Development Theory
Authors: Rinupriya K.  , Dr. Preetha C.
Published: February 2024

Morality is a cornerstone of a sustainable and healthy society; it shapes individuals’ behaviours and contributes to the overall harmony of a community. The profound impact of morals on society has prompted investigations into their developmental processes within individuals. American psychologist, Lawrence Kohlberg insinuated a comprehensive theory of moral development that stipulates a outline for understanding the stages individuals traverse on their moral journey from childhood to adulthood. Kohlberg’s theory delineates six stages across three levels: preconventional, conventional, and post-conventional. This study seeks to use Kohlberg’s theory in the dystopian fiction Poster Girl by Veronica Roth, with a specific focus on the character Sonya Kantor. Sonya undergoes a transformative moral journey, after recognising the inadequacies in her previously held values and beliefs. The research analyses Sonya’s moral development in alignment with the six stages delineated by Kohlberg, shedding light on the intricate nuances of her evolving moral perspectives.

Population Demographics and Other Issues for the Massive Ra World Ship Model – Part 1
Authors:   Interstellar Research Centre, Stellar Engines Ltd, Long Kelvin
Published: February 2024

A world ship is a massive spacecraft carrying a human crew on a trip to the stars over many generations that may take millennia to complete the crossing. It is completely independent of any resource supply chains from back home and is the initial foundations upon which an interstellar settlement may grow into a fully-matured civilisation. Strategies for sending humans around other stars depend on the ability to construct large World Ships which are of order 1011 tons in mass, 100 km in length and host large populations of millions of people over many generations of lifetime. A mission architecture is constructed for a 1 million population carrying capacity growing to 10 million, based on an original 1984 published model which achieves a cruise speed of 1,500 km/s or 0.5% the speed of light (c) for a 1,000 year trip time. This is for a concept called Ra, named after a god who drove his sun chariot across the sky. We discuss how the world ship population is divided into categories. We also discuss the critical issue of population demographic and economics. Power supply and habitat spin rate are also discussed. It is concluded that the design of a society within a world ship presents challenges for social-cultural philosophers and the adoption of a free market economy. This paper is the first part to a follow up which will describe a world ship driven by an inertial confinement fusion engine. Keywords: World Ships, Interstellar Studies

Published: February 2024

La inclusión educativa está incluida en las políticas de muchos países europeos, entre ellos, Italia y España. Este estudio tiene como objetivo
conocer y comparar los sistemas educativos de ambos países
en relación a la educación inclusiva. Asimismo, se pretende analizar la organización escolar para la atención del alumnado con necesidades educativas especiales y la formación inicial del profesorado en inclusión educativa en la educación superior universitaria. Para ello, se siguen las fases propias del método de Educación Comparada. Se emplea el análisis documental como herramienta para la extracción de datos. Se examinan diversas categorías organizadas de manera jerárquica. Los resultados indican diferencias significativas en la atención al alumnado con necesidades educativas especiales en ambos países destacando como indicador comparativo la modalidad de escolarización. Asimismo, se observa que el concepto de necesidades educativas especiales no es el mismo, lo que puede suponer una atención diferente para el alumnado y, por lo tanto, una intervención educativa más inclusiva en un país que en otro. Se resalta la importancia de la formación inicial y permanente del profesorado para la atención de este tipo de alumnado priorizando contenidos inclusivos dentro de los planes de estudio de las universidades. Esta investigación sugiere la eliminación del tradicional modelo dual de separación entre el docente curricular y el docente especializado de apoyo ya que parece ser inadecuado para representar una realidad educativa inclusiva

Published: February 2024

Phytoremediation is a new, cost-effective remediation technique. Sunflower, a plant grown in Pb- and Zn-contaminated soils, underwent pot trials to examine its biomass and determine how well may remove the metals. According to the findings, the fresh and dry weights of the developing plants gradually reduced, as the amount of heavy metals in the soil increased. The fresh weights of the shoot and root were decreased by the application of 835 mg/kg soil of Pb and 598 mg/kg Zn. The maximum concentration of lead and zinc in the shoot (146.27and 277.83 mg/kg) and roots (589.77 and 287.97 mg/kg, respectively) was recorded in the plant cultivated in contaminated soil. The root growing on soil treated with 835 mg/kg had the maximum bioaccumulation of lead. The control soil had the longest plant shoot and root lengths, averaging 75.67 cm and 9.5 cm, respectively. Under a soil Pb concentration of 835 mg/kg, the shortest plants had shoots that measured 58.5 cm and roots that measured 6 cm. Similarly, when the soil was treated with 598 mg/kg soil zinc, the plant?s shoot and root decreased dramatically by 55.67 cm and 7 cm, respectively. As a result, the study shows that sunflower plants were better at absorbing lead and zinc, and we recommend using them to clean up soil that has been contaminated with these metals. .

El trabajo del profesorado formal en México es uno de los problemas latentes que ha tenido el ámbito educativo, reflejado en las evaluaciones estandarizadas tanto nacionales e internacionales que han dejado al descubierto no sólo la funcionalidad de los planes y programas educativos de cada gobierno, pero al mismo tiempo la capacidad de los principales actores educativos tomando máxima relevancia la labor docente (Escudero 2003). La investigación tiene como prioridad conocer el grado de influencia en el desarrollo del acompañamiento docente en el trabajo de la enseñanza y aprendizaje dentro del entorno de la Escuela Secundaria Técnica #32 y como el estudiante se genera una percepción del maestro. El enfoque que se determinó fue cuantitativo y el diseño es transversal, descriptivo y correlacional causal. Dentro del proceso de hacer recolección de los datos se utilizó como medio investigativo, la encuesta bajo un instrumento con escala de Likert la cual se sometió a una medición por el coeficiente de alfa de Cronbach dando como resultado una fiabilidad de .831. La muestra representativa estuvo constituida por 250 estudiantes de primer grado de secundaria. En consecuencia, a los datos que resultaron durante el proceso de la investigación, se encontró que existe una percepción no agradable del docente hacia el estudiante. Tomando en cuenta los resultados, se indica que el accionar docente y su práctica docente debe ser modificada y adecuarla a las necesidades propias de los alumnos para que se genere una percepción adecuada y positiva del alumno hacia el profesor.

Development of improved line is one of the major activities in hybrid tomato breeding. The aim of this study was to identify improved lines based on horticultural traits, total soluble solid (TSS) and diseases resistance particularly tomato yellow leaf curl virus (ToLCV). The genotypes consisted of improved lines, jointless tomato, cherry tomato and beta carotene rich lines. These lines were evaluated in field experiment and screened against ToLCV resistance under natural field condition for two years. Molecular markers based assays were performed for resistance genes to ToLCV (Ty-2 and Ty-3), late blight (Ph-3) and root knot nematode (Mi1-2). Based on fruit yield, promising genotypes were improved lines (VRT-06, VRT-19, VRT-34 and VRT-51), jointless (EC-605037 and EC-695037), cherry tomato (VRCRT-5), and beta-carotene line (KB-20). High TSS was noticed in improved line VRT-67 (5.36 °Brix), jointless EC-695037 (5.37 °Brix) and cherry tomato VRCYT-3 (8.22 °Brix). High ToLCV resistance was recorded in improved lines (VRT-06, VRT-19, VRT-30, VRT-34, VRT-50, VRT-51, and VRT-67), jointless (EC-695037, EC-605037, EC-605094, KB-Jointless and New-Jointless), cherry tomato (VRCYT-3, VRCYT-5, VRCYT-9 and VRCYT-15), and beta carotene (KB-2, KB-3-1, KB-3-2, KB-5, KB-10, KB-14, KB-17 and KB-20). Tomato line VRT-02 having dwarf plant type was found suitable for pot culture, whereas line H-88-78-2 had very delayed and partial fruit ripening. Thus, our study identified promising lines for breeding application for economically important horticultural traits.

Tomato is one of the most popular vegetable crops nationally and internationally used by human beings either cooked and uncooked in various forms including processed products. Various types of diseases are affecting the crop ate starting from its nursery to post-harvesting. Among these, the majority of the diseases are caused by different genera of fungi. Soil-borne fungal diseases are most difficult for manage once the diseases appear in standing tomato crops. A field experiment was conducted by synthesizing different management modules to find the most economical, sustainable and eco-friendly. Based on three years of continuous experimentation on the variety Kashi Aman of tomato for the management of fungal diseases in the nursery and main field, three modules are recommended. The integrated module was the best and most economical. Alternatively, for organic and pesticide-free production of tomato variety Kashi Aman for domestic and international market biological module may be recommended in this area which will be long lasting, absolutely ecofriendly and economical. Good Agricultural Practices (G.A.P) may also be recommended in this area because the module is absolutely pesticide residue-free, sustainable, eco-friendly, long-lasting, organic-based and highly suitable for export.

The importance of fresh fruits and vegetables in a healthy diet is well-established but concerns about pesticide residues have raised questions about their safety. This study investigated the effectiveness of common household methods for decontaminating the deltamethrin residue from tomato, okra, bitter gourd, cowpea, and green chili. The residue was estimated using gas-chromatography. The technique was validated through recovery, limit of detection (LoD), limit of quantitation (LoQ). Various processing techniques, including washing with tap water, salt water, vinegar, baking soda solutions, blanching and sonication were evaluated. The study found that these household methods significantly reduced deltamethrin residues in the tested vegetables. Boiling water washing (blanching), and sonication with distilled water and vinegar solution washing led to reductions of approximately 70-80% in deltamethrin residues. Additionally, warm water washing and blanching were effective, with reduction percentages ranging from 46 to 79%. The results varied depending on the type of vegetable and the method employed. However, overall these techniques showed promise in reducing the deltamethrin residues. Therefore, it is important to adopt multiple decontamination strategies such as thorough washing and cooking, to mitigate the potential risks associated with pesticide residues in vegetables.

The commonly cultivated potato is a tetraploid and belongs to the species Solanum tuberosum, which includes two subspecies viz. ssp. tuberosum adapted to long days and ssp. Andigena adapted to short days. The conventional potato breeding programmes depend mainly on the identification of promising parental lines for making desired crosses, the creation of genetic variability through the crossing and subsequently the selection of desirable recombinants for further evaluation and vegetative propagation. During the last seven decades, Indian Council of Agricultural Research - Central Potato Research Institute (ICAR -CPRI) has developed and released as many as 69 improved varieties and one TPS population. These varieties cater to the need of the farmers across the country; and have superior agronomic attributes and resistance to different biotic and abiotic stresses. The somatic hybrids has been produced successfully by utilization of wild solanum species like S. etuberosum, S. cardiophyllam and S. pinnetisectum. Further, considerable work has been done in potato applying molecular biology and genomics approaches to address biotic and abiotic stress and quality traits.
