Optimising conservation efforts requires an accurate record of the extant species as well as their geographic distributions. Nevertheless, most current conservation strategies start from an incomplete biodiversity inventory. Argentina has an extraordinary diversity of species, however, until now an updated inventory of its fauna has not been carried out. In this context, the main objective of this work is to present the results of the first national inventory of vertebrate species. Experts from each major vertebrate taxonomic group assembled and compiled its respective inventory. The information gathered included taxonomic rank, conservation status, endemism and geographic distribution. Species richness and representativeness were calculated for each taxonomic group, distinguishing between native, endemic and exotic, for each Argentinian province. Our results show Argentina harbours 3,303 species: 574 marine fish, 561 freshwater fish, 177 amphibians, 450 reptiles, 1,113 birds, and 428 mammals. Native species constitute 98.1% of the total taxa. The results achieved were spatially represented showing a pattern of higher richness from north to south and from east to west. Species considered as threatened account for 17.8% and 15.2% are endemic. There are five Extinct species. These results provide key information on developing strategies and public policies at the national and provincial levels and constitute a tool for the management and conservation of biodiversity.
Las áreas naturales protegidas (AnPs) son esenciales para la conservación de la biodiversidad. Están destinadas a mantener ecosistemas naturales operativos, actuar como refugios para las especies y mantener procesos ecológicos in-capaces de sobrevivir en los entornos terrestres y marítimos con un mayor nivel de intervención (dudley, 2008). El conocimiento de las especies presentes (o ausentes) en un AnP brinda información indispensable para valorarla correctamente. Los inventarios son necesarios para obtener infor
This study contributes to the knowledge of continental fishes recovered from sedimentary successions corresponding to the Bonaerean Stage/Age (late mid-Pleistocene) in the locality of Centinela del Mar, General Alvarado County, Buenos Aires province, Argentina. At this site we describe fossil fishes from a palaeolagoon, including Corydoras sp., Pimelodella sp., Rhamdia sp., Oligosarcus sp., small undetermined characids, Jenynsia sp. and Odontesthes sp. The recovered ichthyofaunal assemblage comprises at least seven taxa of Paranaean lineage. The taxonomic composition of the palaeoichthyofauna is quite comparable to that presently found in Bonaerean Watercourses of the Atlantic Drainage ecoregion. This suggests that local ichthyofaunal communities have remained relatively stable since the late mid-Pleistocene.
es uno de los bosques tropicales lluviosos más amenazados de la Tierra, del cual subsiste solamente el 16,8% de su cobertura original (Fundación Vida Silvestre Argentina & WWF, 2017). Es una de las ecorregiones incluidas en las Global 200, un complejo de quince ecorregiones terrestres que recorre la costa atlántica de Brasil y se extiende hacia el oeste por Paraguay oriental y el noreste de la Argentina. Este complejo también ha sido identificado como una de las 25 "zonas calientes
