“…The Cerrado encompasses areas from northeastern to southwestern Brazil, eastern Bolivia, and northern Paraguay. With deep soils rich in Aluminum, the Cerrado is irrigated by perennial watercourses (Coutinho 2006); its dry season lasts four months per year, with the rainfall concentrated in the wet season, and averaging annual values of 800–2000 mm (Ab’Sáber 1974, Nimer 1989). Neighboring the Cerrado is the Caatinga, a biome that occupies an extensive area (800,000 km 2 ) of northeastern Brazil (Prado 2008).…”

Citation: Gutiérrez EE, Marinho-Filho J (2017) The mammalian faunas endemic to the Cerrado and the Caatinga. ZooKeys 644: 105-157. https://doi.org/10.3897/zookeys.644.10827 AbstractWe undertook a comprehensive, critical review of literature concerning the distribution, conservation status, and taxonomy of species of mammals endemic to the Cerrado and the Caatinga, the two largest biomes of the South American Dry-Diagonal. We present species accounts and lists of species, which we built with criteria that, in our opinion, yielded results with increased scientific rigor relative to previously published lists -e.g., excluding nominal taxa whose statuses as species have been claimed only on the basis of unpublished data, incomplete taxonomic work, or weak evidence. For various taxa, we provided arguments regarding species distributions, conservation and taxonomic statuses previously lacking in the literature. Two major findings are worth highlighting. First, we unveil the existence of a group of species endemic to both the Cerrado and the Caatinga (i.e., present in both biomes and absent in all other biomes). From the biogeographic point of view, this group, herein referred to as Caatinga-Cerrado endemics, deserves attention as a unit -just as in case of the Caatinga-only and the Cerrado-only endemics. We present preliminary hypotheses on the origin of these three endemic faunas (Cerrado-only, Caatingaonly, and Caatinga-Cerrado endemics). Secondly, we discovered that a substantial portion of the endemic mammalian faunas of the Caatinga and the Cerrado faces risks of extinction that are unrecognized in the highly influential Red List of Threatened Species published by the International Union for Conservation of Nature (IUCN). "Data deficient" is a category that misrepresents the real risks of extinction of these species considering that (a) some of these species are known only from a handful of specimens collected in a single or a few localities long ago; (b) the Cerrado and the Caatinga have been sufficiently sampled to guarantee collection of additional specimens of these species if they were abundant; (c) natural habitats RESEARCH ARTICLE Launched to accelerate biodiversity research A peer-reviewed open-access journalEliécer E. Gutiérrez & Jader Marinho-Filho / ZooKeys 644: 105-157 (2017) 106 of the Cerrado and the Caatinga have been substantially altered or lost in recent decades. Failures either in the design of the IUCN criteria or in their application to assign categories of extinction risks represent an additional important threat to these endemic faunas because their real risks of extinctions become hidden. It is imperative to correct this situation, particularly considering that these species are associated to habitats that are experiencing fast transformation into areas for agriculture, at an unbearable cost for biodiversity.

“…A costa atlântica das regiões Sudeste e Sul do Brasil apresenta formações abertas (restingas acompanhadas de dunas), que propiciam ambientes com vegetação mais rala e xerofítica, em dois trechos bem afastados: uma porção sudeste, que vai do litoral capixaba até a região sul fluminense de Marambaia (Suguio e Tessler, 1984;Rio de Janeiro, 1994), correspondente aos setores 24 a 29 de Ab'Saber (2006), e uma porção sul, que se estende de Florianópolis até o Uruguai (Reitz, 1961;Hueck e Seibert, 1972;Klein, 1978;Quadros e Pillar, 2002), correspondente aos setores 41 a 49 de Ab'Saber (2006). Em ambas as porções, os terrenos terciários e quaternários com vegetação aberta de restingas e dunas não são plenamente contínuos, havendo interrupções breves em diversos pontos da costa (e.g.…”

“…Los estudios sobre las zonas costeras y adyacentes vienen aumentando considerablemente en los últimos años, y gradualmente adquieren gran importancia en la planificación ambiental y territorial, principalmente, en áreas donde la intervención humana provoca la destrucción de algún patrimonio o interfiere de modo drástico en los ecosistemas (Ab'Saber;2000;Hoefel, Max Furrier.

Este trabajo contempla una caracterización geomorfológica como base para la planificación ambiental y territorial en una región costera de Brasil. Desde el punto de vista geomorfológico, el área de estudio se encuentra ubicada sobre las mesetas y tierras bajas costeras, donde predomina la Formación Barreiras y sedimentos del Cuaternario. Esta área posee una grande diversidad pedológica, con diversos usos y ocupaciones. La integración de los datos obtenidos, generados, analizados y discutidos, fueron sintetizados en la plancha de fragilidad de los ambientes naturales y antrópicos que permite visualizar cómo los componentes del medio físico se integran y pueden influenciar en las dinámicas socio-económicas. Esta integración de datos es de fundamental importancia en la planificación ambiental y territorial, principalmente en países en desarrollo como Brasil y Costa Rica, donde en muchas regiones hay pocos datos o los datos son dispersos.
