Última The generic affinity of Caiophora pulchella (Loasaceae, Loasoideae) Darwiniana Acuña Castillo,Rafael; Weigend,Maximilian. The history of the nomenclatural changes and past hypotheses on the relationships of Caiophora pulchella are presented. The identity of voucher specimens, identified as C. nivalis in previous phylogenetic studies, is reassessed based on fruit morphology. The validity of C. pulchella is reconsidered and can be confirmed as a member of the genus Caiophora based on both morphological and molecular data. Alternative generic placements are rejected.

Ano: 2018 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S0011-67932018000100008 Multiple pathways to sustainability in the city: the case of San Juan, Puerto Rico Ecology and Society I examined the multiple visions of the future of the city that can emerge when city actors and organizations reconfigure themselves to address sustainability. In various cities worldwide, novel ideas, initiatives, and networks are emerging in governance to address social and ecological conditions in urban areas. However, cities can be contested spaces, bringing a plurality of actors, network configurations, preferences, and knowledge that shape the politics over desirable pathways for future development. I used the knowledge-action systems analysis (KASA) approach to examine the frames and knowledge systems influencing how different actors involved in the land governance network of the city of San Juan constructed visions for the future of the city....

Ano: 2014 Trends in total rainfall, heavy rain events, and number of dry days in San Juan, Puerto Rico, 1955-2009 Ecology and Society Nieves-Santiango, Alejandro; Graduate School of Public Health and Center for Public Health Preparedness, University of Puerto Rico-Medical Sciences Campus; alejandro.nieves1@upr.edu. Climate variability is a threat to water resources on a global scale and in tropical regions in particular. Rainfall events and patterns are associated worldwide with natural disasters like mudslides and landslides, meteorological phenomena like hurricanes, risks/hazards including severe storms and flooding, and health effects like vector-borne and waterborne diseases. Therefore, in the context of global change, research on rainfall patterns and their variations presents a challenge to the scientific community. The main objective of this research was to analyze recent trends in precipitation in the San Juan metropolitan area in Puerto Rico and their relationship with regional and global climate variations. The statistical trend analysis of precipitation... Tipo: Peer-Reviewed article Palavras-chave: Climate variability; Puerto Rico; Rainfall patterns; San Juan; Trend analysis. Ano: 2014 Primer registro de artropodofauna cadavérica en sustratos humanos y animales en San Juan, Argentina Rev. Soc. Entomol. Argent. Aballay,Fernando H.; Murúa,Albérico F.; Acosta,Juan C.; Centeno,Néstor. En el presente trabajo se estudiaron los artrópodos carroñeros que acudieron a cadáveres de vertebrados al aire libre en la provincia de San Juan, Argentina. El objetivo fue inventariar la composición específica de la artropodofauna cadavérica, asociada a diferentes sustratos de vertebrados en descomposición. Se colectaron muestras de artrópodos sobre restos animales y humanos en condiciones de campo y sobre cadáveres de cerdos domésticos colocados al aire libre bajo condiciones controladas. Se registraron, por primera vez para la provincia de San Juan, 40 especies de artropodofauna tanatológica incluidas en cuatro órdenes y 15 familias. Se incorpora, como primera cita para la fauna forense argentina, un necrófago: Megelenophorus americanus Lacordaire...

Ano: 2008 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S0373-56802008000200023 Conodontes sandbianos (Ordovícico Superior) en la Quebrada La Pola, Sierra de Villicum, precordillera de San Juan (Argentina) Ameghiniana Heredia,Susana; Milana,Juan Pablo. Se da a conocer nueva información bioestratigráfica y paleoambiental de la Formación La Pola, unidad siliciclástica con niveles mixtos de areniscas y lutitas que incluyen braquiópodos, que aparece en contacto con el techo de la Formación La Cantera en la Quebrada de La Pola (Sierra de Villicum). De los niveles bioclásticos superiores se ha rescatado una conodontofauna que se asigna a la Biozona de Amorphognathus tvaerensis, característica del Ordovícico Superior temprano (Sandbiano bajo). La determinación de Baltoniodus variabilis Bergström permite definir la subzona homónima. Las afinidades paleobiogeográficas de la conodontofauna corresponden claramente a la provincia del Midcontinent, aunque también se observan influencias noratlánticas, mientras que...

Ano: 2010 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S0002-70142010000400007 Some trilete spores from Lower Carboniferous strata of the Rio Blanco Basin, western Argentina Ameghiniana Pérez Loinaze,Valeria. A new miospore genus Ductilispora is described to accommodate simple acamerate miospores, which have a distal ornament of folds like muri or thickenings. Five new species of trilete spores are defined: D. circularis sp. nov., D . longitudinalis sp. nov., D. corrugatus sp. nov., Verrucosisporites cortaderensis sp. nov., Dibolisporites malimanensis sp. nov. and Indotriradites variabilis sp. nov. The specimens have been recovered from the Malimán and the Cortaderas Formations (Early Carboniferous), in La Cortadera creek, San Juan province, Argentina.

Se presentan los primeros registros paleontológicos de la Formación Lagarcito (Albiano) provenientes de la sección La Yesera Sur, sobre la ladera oriental de la sierra de Guayaguas, en el sudeste de la provincia de San Juan, en el centro-oeste de Argentina. Varios episodios lacustres se detectaron a lo largo del perfil, pero sólo en tres de ellos el contenido paleontológico y palinológico resultó abundante. Se describen e ilustran ocho especies de algas clorofíceas, tres de conchóstracos y once de ostrácodos no marinos. La asociación es indicadora de un ambiente lacustre somero, con buena disponibilidad de nutrientes en una primera etapa y alta evaporación, demostrado por la presencia de yeso interestratificado hacia la parte superior de cada episodio...

Albinism has been widely reported for diverse group of vertebrates. However, scoliosis is a rare abnormality. In this work, the first record of partial albinism and scoliosis case in tadpole of the frog Odontophrynus occidentalis is being presented. The individual was captured in Quebrada de las Flores, Sierra Pie de Palo, Caucete Department, San Juan Province, Argentina.
