Preliminary data on movements and health condition of the first radio-collared huemul (Hippocamelus bisulcus) population study in Argentina

Aun cuando solo quedan menos de 500 ejemplares de huemul patagonico (Hippocamelus bisulcus) en Argentina, existe escasa información sobre su ecología y dinámicas poblacionales. Por primera vez en la historia de Argentina, se instalaron equipos de radio telemetría en un grupo de huemules para entender de mejor forma los factores que no han permito la recuperación de las poblaciones. Durante el invierno del 2017, se procedió a la captura de seis ejemplares en seis días (tres de cada género), al interior del parque protegido Shoonem, provincia de Chubut. Se presenta en este artículo una descripción de las condiciones particulares del clima y las características del paisaje que serán útiles considerar para mejorar el éxito de capturas de huemules, particularmente en Argentina. Aun cuando los animales capturados presentaban un aspecto sano a primera vista, durante la última evaluación (25 enero 2018), identificamos signos clínicos de enfermedad en 5 de 6 animales capturados durante el procedimiento; incluyendo renguera, pezuñas deterioradas, perdida de 2-7 incisivos y atrofia muscular. Los desplazamientos registrados desde el sitio de captura en régimen de invernada a zonas de uso estival fueron 187% mayores en las hembras comparativamente a los machos.Even though less than 500 Patagonian huemul (Hippocamelus bisulcus) remain in Argentina, information on their population ecology and dynamics is severely lacking. For the first time in Argentine history, radio-telemetry collars were placed on a group of huemul to better understand the factors behind the population?s failure to recover. Six adult huemul (3 of each gender) were captured in six days, the winter of 2017, inside Shoonem Protected Park, Chubut province. In this article, we present a description of the unique climatic conditions and characteristics of the environment that would be useful to consider in order improving the success of huemul captures, particularly in Argentina. Despite the outwardly healthy appearance of each radio-collared huemul on the last observation date (January 25, 2018), we identified clinical symptoms of disease in 5 of these 6 animals during their capture; these included lameness, affected hoof, exfoliation of 2-7 incisors, and muscular atrophy. Movement distances from the winter capture site to maximum summer distance recorded were 187% greater for females than males (n=6, p =0.05, Mann Whitney).Fil: Smith Flueck, Jo Anne.

A community small-scale wind generation project in Peru

Electrification systems based on renewable energy have proven to be suitable for providing decentralized electricity to isolated communities. Electricity generated through wind power is one of the technical options available, although infrequently used to date. This article aims to describe the main aspects of technical design, implementation and management of the first small-scale community wind generation project for rural electrification in Peru. This project took place in the community of El Alumbre, in the region of Cajamarca, which is a mountainous area characterized by low to medium wind speeds. This project, implemented by Soluciones Prácticas – Practical Action (Peru), brought electric power to the 33 households (a total of 150 inhabitants) as well as the school and health center of the community.Peer ReviewedPostprint (published version

PERCEPÇÃO DO DISCENTE SOBRE PRODUTIVIDADE CIENTIFICA EM UM PROGRAMA DE PÓS-GRADUAÇÃO STRICTO SENSU

No cenário vivenciado pelos discentes nos Programas de Pós-graduação stricto sensu há uma preponderância em considerar que eles são ambientes privilegiados para formar pesquisadores como também para produção de conhecimento. Os números da última década referentes à produção científica no Brasil, maiormente gerada nas pós-graduações, apresentam-se de modo crescente, no entanto esses valores não apontam a realidade sobre as estruturas de poder e as variáveis cognitivas, emocionais, comportamentais e culturais que envolvem a pressão por publicar. O objetivo desta pesquisa exploratório-descritiva foi investigar a percepção do corpo discente em um Programa de Pós-graduação stricto sensu sobre produtividade científica. A abordagem quali-quantitativa foi operacionalizada por meio de entrevistas semiestruturadas e aplicação de questionário fechado com escala Likert. Na etapa qualitativa, foram realizadas sete entrevistas com acadêmicos e na fase quantitativa o levantamento incluiu todos os alunos matriculados. A confiabilidade de coerência interna da escala foi avaliada através da divisão em metades e pelo alfa de Cronbach. Para a apreciação do relacionamento entre os 16 itens se realizou uma análise fatorial, usando o método de componentes principais para obtenção dos fatores e rotação varimax. Descartaram-se cinco variáveis e as onze restantes ficaram expressas em três fatores. A avaliação da parecença entre os pós-graduandos foi efetuada com a análise de correspondências múltiplas e a análise de conglomerados. Com base nas percepções constatadas por meio de análises do discurso e estatística, foi possível verificar que a maioria dos discentes se sente pressionada pelos prazos e exigências de publicações. Entretanto, consideram que essa cobrança desenvolve a capacidade de pesquisador e insere o aluno na pesquisa. Acham ainda que há cobrança quanto à produção de artigos nas disciplinas, mas não há acompanhamento suficiente por parte de alguns docentes, que também se sentem pressionados para publicar. Os resultados permitem concluir que os discentes percebem que há realmente pressão pela produtividade acadêmica e que o fator tempo torna-se o mais preocupante. Porém, essa pressão não se configura para eles como negativa

Role of the different eyes in the visual odometry in the Wolf spider Lycosa tarantula (Araneae, Lycosidae)

The wolf spider Lycosa tarantula returns home by means of path integration. Previous studies demonstrated: (i) that the angular component of the outbound run is measured using a polarized-light compass associated with the anterior median eyes; (ii) changes in direction of the substratum are detected by the anterior lateral eyes (ALEs); and (iii) in relation to the linear component of the outbound run, an increase of optic flow, in either the lateral or ventral fields of view, caused spiders to search for the burrow at a point nearer to the goal. However, the role of the secondary eyes [ALEs, posterior lateral eyes (PLEs) and posterior median eyes (PMEs)] in the perception of this optic flow and the importance of them for gauging the distance walked is still unknown. In this study, lateral or ventral gratings of wavelength λ=1 cm were used, with two groups of spiders in each setup: (1) PLEs+PMEs covered and (2) ALEs covered. The largest reduction in the distance walked to return to the burrow was observed with the ventral grating/ALEs covered. These results show the importance of the previously neglected ALEs for the visual behavior of these spiders. The possibility of gathering information for locomotion from the three pairs of secondary eyes in the mushroom bodies is discusse

On the other hand, when they were asked to support class work, they preferred to remain silent. It was also seen that they had difficulty expressing their emotions. Given the nature of the problem, the general objective was formulated: Design and implement a didactic strategy that contributes to the development of the oral competence of Seventh grade 2 students. This work seeks to answer the following research question: What didactic strategy is Can you design and implement to contribute to the development of oral communicative competence in seventh grade students? Determined this situation gave way to the line of research - action that is situated from a mixed approach. Among the information gathering techniques, direct observation was used, where the elaboration of surveys, evaluation matrix for oral support, survey of the 30 students under study and 10 teachers who guide in this grade were implemented. Therefore, the design of the activities played a fundamental role, since they attract the student. Activities were then designed that promote the use of good semantics, syntax, verbal fluency, argumentation, intonation, understanding and pragmatics, focused mainly on their spontaneity in answering a question, holding a dialogue or expressing themselves in front of a general public. Subsequently, the results of the research process are presented, the conclusions reached by the authors. It is clear that with a correct use of language, it is possible to strengthen oral competence in these young people.

Assessment of habitat quality and landscape connectivity for forest-dependent cracids in the Sierra Madre del Sur Mesoamerican biological corridor, Mexico

Assessing landscape connectivity allows us to identify critical areas that impede or facilitate the movement of organisms and their genes and to plan their conservation and management. In this article, we assessed landscape connectivity and ecological condition of the habitat patches of a highly biodiverse region in Chiapas, Mexico. We employed data of three cracid species with different characteristics in habitat use and mobility. The habitat map of each species was derived from a spatial intersection of the models of potential distribution and a high-resolution map of current land cover and land use. The ecological condition of vegetation types was evaluated using 75 field plots. Structure of landscape was estimated by fragmentation metrics, while functional connectivity was assessed using spatially explicit graph analysis. The extent of suitable habitat for Oreophasis derbianus, Penelopina nigra, and Penelope purpurascens correspond to 25%, 46%, and 55% of the study area (5,185.6 km2), respectively. Although the pine-oak forests were the most fragmented vegetation type, habitats of the three species were well connected, and only 4% to 9% of the fragments located on the periphery of the corridor had low connectivity. Landscape connectivity depends mainly on land uses with an intermediate and lower ecological condition (secondary forests and coffee agroforestry systems). Therefore, we suggest that in addition to promoting the improvement in connectivity in fragmented forests, conservation efforts should be aimed at preventing the conversion of mature forests into agricultural uses and maintaining agroforestry systems

Semivalues: power, potential and multilinear extensions

The notions of power and potential, both defined for any semivalue, give rise to two endomorphisms of the vector space of all cooperative games on a given player set. Several properties of these linear mappings are stated and their action on unanimity games is emphasized. We also relate in both cases the multilinear extension of the image game to the multilinear extension of the original game
