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published lists -e.g., excluding nominal taxa whose statuses as species have been claimed only on the basis of unpublished data, incomplete taxonomic work, or weak evidence.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.

“…Esta adaptación permite a este grupo de roedores aprovechar una amplia gama de recursos asociados a cuerpos de agua y los ubica ecológicamente dentro de las comunidades más diversas de mamíferos pequeños en el Neotrópico (Voss 1988). En Perú habitan siete especies de roedores semiacuáticos ), de los cuales cuatro son endémicas para el país, conocidas de muy pocos ejemplares depositados en museos y algunos se encuentran amenazados (Musser & Gardner 1974, Voss 1988, Malygin et al 1994, Pacheco & Vivar 1996, Pacheco & Ugarte-Nuñez 2011, Prado & Percequillo 2013, D.S.

En el presente trabajo se documenta la diversidad de mamíferos pequeños en la Zona Reservada Sierra del Divisor (ZRSD). Se evaluaron seis localidades entre 2011 y 2013 utilizando técnicas de captura estándar (trampas Víctor, Tomahawk, Pitfall y redes de niebla). Se registró un total de 67 especies (cinco marsupiales, 10 roedores y 52 murciélagos), 32 de las cuales son nuevos registros para la ZRSD y dos son especies de roedores raras y endémicas del Perú, la “rata acuática peruana” Neusticomys peruviensis (Cricetidae: Ichthyomyini) y el “Ratón acuático de Ucayali” Amphinectomys savamis (Cricetidae: Oryzomyini). El marsupial Marmosops bishopi; los roedores Neacomys minutus, Euryoryzomys macconnelli, Scolomys melanops y Proechimys kulinae; y los murciélagos Artibeus planirostris y Rhinophylla pumilio fueron las especies más abundantes. Nuestros hallazgos demuestran la importancia de la re-categorización de la Zona Reservada al estatus de Parque Nacional, como una contribución significativa para la conservación de los mamíferos del Perú.

“…This rodent is confined to lowland areas with strong seasonal rainfall, like grasslands and wetlands, found throughout the Chaco, Cerrado and Caatinga (Figure 1; Anderson, 1997;D'Elia et al, 2008;Pardiñas et al, 2004;Prado and Percequillo, 2013;Voss and Myers, 1991). Despite its extensive range, P. simplex was classified as rare (difficult to collect) and not abundant by Bonvicino et al (2002).…”

“…Aragona (2008) provided a review of the small non-volant mammal species recorded in the Pantanal floodplain and the adjacent areas in the plateau, and none of the studies mentioned by her reports P. simplex in this region. As far as is known, the closest collecting localities of the species to the Pantanal limits are Parque Nacional de Noel Kempff Mercado, Santa Cruz, Bolivia (14°16'S, 60°52'W) and Gruta São Miguel, Mato Grosso do Sul, Brazil (21°06'S, 56°34'W) according to Prado and Percequillo (2013: figure 37).

First record of Pseudoryzomys simplex (Cricetidae, Sigmodontinae) in a flooded area of the Pantanal, Brazil

et al. 2016

View full text Add to dashboard Cite

Pseudoryzomys simplex is a small to medium sized terrestrial rodent confined to lowland open areas with strong seasonal rainfall throughout the Chaco, Cerrado and Caatinga. Despite its extensive range, the species is difficult to trap. In this report we provide the first record of P. simplex in the Pantanal, where three specimens were collected in a pasture of exotic grass. The specimens are morpometrically similar to the population from Paraguay (Chaco). In this sense, our report shows how interesting a taxonomic review of the species would be to better understand the real significance of the geographic variation herein observed.Keywords: false Oryzomys, geographic distribution, Pantanal wetland. Primeiro registro de Pseudoryzomys simplex (Cricetidae, Sigmodontinae)em área alagada do Pantanal, Brasil ResumoPseudoryzomys simplex é um roedor terrestre de pequeno a médio porte que ocorre em áreas abertas de planícies com fortes precipitações sazonais ao longo dos Chaco, Cerrado e Caatinga. Apesar de sua extensa distribuição, a espécie é difícil de ser capturada. No presente estudo, fornecemos o primeiro registro de P. simplex no Pantanal, onde três espécimes foram coletados em uma pastagem de capim exótico. Os espécimes são morfometricamente semelhantes à da população do Paraguai (Chaco). Neste sentido, o nosso relatório mostra quão interessante seria uma revisão taxonômica das espécies para melhor compreender o significado real da variação geográfica aqui observada.Palavras-chave: falso Oryzomys, distribuição geográfica, Pantanal.
