Conjunto de datos de las familias Baetidae (Ephemeroptera) y Elmidae (Coleoptera) de las Yungas argentinas RESUMEN. Las Yungas o Bosques Subtropicales de Montaña representan una de las ecorregiones más biodiversas de Argentina. Su distribución sobre las cadenas montañosas andinas ayuda a retener el agua, generando los ecosistemas lóticos. El objetivo de este trabajo es dar a conocer y describir un conjunto de datos de las familias Baetidae y Elmidae. Estos datos contienen 1.183 registros, 828 pertenecen a la familia Baetidae (15 géneros y 27 especies) y 355 registros a la familia Elmidae (10 géneros y 16 especies). Se muestrearon 10 de las 24 áreas protegidas, existiendo sectores de Yungas que no poseen registros, como
R������.Los bosques de ribera se encuentran entre los ecosistemas más vulnerables, y para mantener los servicios que brindan se necesita su restauración ecológica. El objetivo principal de nuestro trabajo fue generar un mapa de zonas ribereñas a fin de identificar bosques, áreas transformadas y oportunidades para restaurar estos ecosistemas en Tucumán, Argentina. Comparamos diferentes anchos de zonas de amortiguación (ZdA): según requisitos legales (60 m) y sugerencias científico-técnicas (100 y 250 m). Para explorar la superficie de unidades de producción agrícola (UPA, lotes catastrales) ubicadas en las ZdA analizamos diferentes regiones agroecológicas y porcentajes de superficie ocupada en las UPA. La cobertura del suelo se cartografió a partir de una clasificación supervisada de imágenes Sentinel en Google Earth Engine. Nuestros resultados revelaron que para alcanzar a cubrir los 60 y 250 m de ZdA se necesitaría restaurar entre 40 y 60% de las zonas ribereñas, respectivamente, en su mayoría bajo agricultura. Si se considera una ZdA de 60 m, las riberas se encuentran ocupadas por usos agrícolas y urbanos en 23.5% (1959 ha) en el pedemonte, 50.9% (7784 ha) en la llanura húmeda y 36.8% (3113 ha) en la llanura seca. Nuestros resultados sugieren que se deben realizar diferentes esfuerzos para restaurar de manera eficiente las distintas regiones agroecológicas. La restauración necesaria para cubrir el requisito legal podría ser una meta alcanzable considerando objetivos globales y regionales. La mayoría de las UPA incluyeron menos de 20% de su superficie en una zona ribereña. Sin embargo, se recomienda incorporar abordajes socio-ecológicos en los proyectos de restauración, a fin de conocer las visiones de los productores, proponer compensaciones y evitar restricciones que afecten la producción agrícola local. El mapeo realizado será una herramienta valiosa para implementar proyectos de restauración en un área prioritaria de la Argentina.[Palabras clave: vegetación de ribera, restauración ecológica, agricultura, gestión ambiental, zona de amortiguación] A�������. Evaluation of the riparian forest deficit in Tucumán. Riparian forests are among the most vulnerable ecosystems. Ecological restoration is needed to maintain the ecosystem services they provide. The main goal of the present study was to generate a map of riparian zones identifying forest and transformed areas as a base for their restoration in Tucumán, Argentina. We compared different buffers width: one according to legal requirement (60 m) and two scientific-technical suggestions (100 and 250 m). To explore the occupation of the agronomic production units (cadastral units) by the buffers, we analyzed riparian land cover among different agro-ecological regions and the percentage of production units area affected. Land cover maps were performed through a supervised classification of Sentinel in Google Earth Engine. Our results revealed that between a 40 and 60 percent of the riparian zones, mainly covered by agriculture, need to be restored to reach the 60 a...
Geographic Information System (GIS) is a system that captures, stores, manipulates, analyzes, manages, and presents spatial or geographical data. As this technological environment has been created to deal with space problems, it is perfectly adaptable to solve these type of issues in the context of vertebrate comparative morphology. The pectoral and pelvic girdles are key structures that relate the axial skeleton with the limbs in tetrapods. Owed to their importance in locomotion, the morphology, development, and morphogenesis of these structures have been widely studied. The complexity of the structures and tissues implied in the development of the girdles make quantitative approaches extremely difficult. The use of GIS technology provides a visual interpretation of the histological data, a general quantitative assessment of the processes taking place during the ontogeny of any structure, and would allow collecting information about the changes in the surface occupied by the different tissues across the ontogenetic processes of any vertebrate taxa. GIS technology applied to map morphological structures would be a main contribution to the construction of the vertebrate ontologies, as it would facilitate the identification and location of the structures. GIS technology would allow also us to construct a shared database of histological quantitative changes across the ontogeny in any vertebrate. The main objective of this study is to use GIS technology for spatial analysis of histological samples such as these of the pelvic girdle using histological cuts of anurans and chicken, allowing thus to construct a morphoscape, analogous to a landscape. This is the first attempt to apply GIS tools to ontogenetic series to infer biological properties of the spatial analysis in the context of comparative biology. More frequent use of this technology would contribute to obtaining more profitable and biologically informative results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
