TL;DR: In this article, the two species Caiman latirostris and C. yacare were included in the Not Endangered category, based on new records about their geographic distribution and populations densities.
Abstract: After more than a decade from the first Red List of the Herpetofauna of Argentina assessed in 2000, we reclassified the two species of argentine caimans, starting from actual information about their biology, biogeography and ecology and including methodological adjustments. As a result, both species Caiman latirostris and C. yacare were included in the Not Endangered category, based on new records about their geographic distribution and populations densities. The criteria applied to the development of management programs of crocodilians in Argentina has improved the knowledge of both species and made a great and wide contribution to several aspects of their biology. The sustainable use of both species of crocodilians has proved to have a minimum impact on wild populations and has put a new value on the wetlands inhabited by this reptiles.

TL;DR: A global, quantitative assessment of the amphibian chytridiomycosis panzootic demonstrates its role in the decline of at least 501 amphibian species over the past half-century and represents the greatest recorded loss of biodiversity attributable to a disease.
Abstract: Anthropogenic trade and development have broken down dispersal barriers, facilitating the spread of diseases that threaten Earth's biodiversity. We present a global, quantitative assessment of the amphibian chytridiomycosis panzootic, one of the most impactful examples of disease spread, and demonstrate its role in the decline of at least 501 amphibian species over the past half-century, including 90 presumed extinctions. The effects of chytridiomycosis have been greatest in large-bodied, range-restricted anurans in wet climates in the Americas and Australia. Declines peaked in the 1980s, and only 12% of declined species show signs of recovery, whereas 39% are experiencing ongoing decline. There is risk of further chytridiomycosis outbreaks in new areas. The chytridiomycosis panzootic represents the greatest recorded loss of biodiversity attributable to a disease.

TL;DR: The lista roja de the herpetofauna of the Republica Argentina, presented by the AHA in 2000, was updated in 2013 with 256 species of lagartijas and anfisbenas as discussed by the authors.
Abstract: Luego de la elaboracion de la primera lista roja de la herpetofauna de la Republica Argentina,realizada en el ano 2000, son numerosos los cambios y estudios efectuados en los diferentesgrupos de saurios de la Argentina. Si bien hay avances realizados en todas las ramas de labiologia relacionadas a las lagartijas, los progresos taxonomicos y ecologicos son los mas evidentes.Debido a estos progresos, y a la implementacion de sustanciales modificaciones conrespecto a la metodologia que se utilizara en el ano 2000, un grupo de veintisiete especialistasde diferentes instituciones academicas de la Argentina aportaron informacion biologica, ecologica,geografica y taxonomica en un taller que permitio reevaluar el estado de conservacionde las 256 especies de lagartijas y anfisbenas de la Argentina. Los resultados obtenidos indicanque setenta y ocho especies se encuentran incluidas en la lista roja (una En Peligro, nueveAmenazadas y 68 Vulnerables), 31 Insuficientemente Conocidas y 147 No Amenazadas. Conrespecto a la categorizacion anterior de la AHA, se agregaron 94 especies, de las cuales 87 sonnuevos taxa, cuatro revalidadas, y otras tres especies fueron incorporadas a la fauna argentina.Asimismo cinco especies fueron extraidas del listado de la fauna de la Republica Argentina.En comparacion con los resultados obtenidas en la categorizacion del ano 2000, observamosque el numero de especies Amenazadas se incremento de cinco a nueve especies y de siete a68 especies como Vulnerable, incluyendo a los generos Phymaturus y Anisolepis. Asimismo, se categorizo como Insuficientemente Conocida a 31 especies contra 108 del ano 2000. Estos resultados son en parte debido al incremento en el conocimiento sistematico, biologico, ecologico y biogeograficos de las lagartijas y anfisbenas de la Argentina, por el cambio radical de la metodologia utilizada y tambien por los efectos de la presion antropica sobre las especies y/o sus habitats.

TL;DR: Results gathered to date reveal a dichotomy of venom phenotypes regarding the relative abundance of the omnipresent phospholipases A2 and 'three-finger' toxins within Micrurus, and two divergent toxin expression phenotypes appear to be related to phylogenetic positions and geographical distributions along a North-South axis in the Americas.
