“…According to Oliveira and Paula (2001), the phenology of Cerrado plants is greatly diversified and fructification happens all year around, including the dry (May to September) and rainy (October to April) seasons. Table 1 shows that fruits consumed by C. penicillata follow this same pattern, although Vilela (2007) reports that fruits are less exploited during the peak of the dry season (June-August). Fruits of Brosimum gaudichaudii, Miconia albicans, M. ferruginata (Miranda and Faria, 2001;Vilela and Faria, 2002), Schefflera macrocarpa (Miranda and Faria, 2001) and M. pepericarpa (D. P. Decanini, personal communication) are eaten by the marmosets.…”

Among placental mammals, only primates have trichromatic color vision, however this is not a uniform condition. Under different genetic status, Old World monkeys have routine trichromacy, while New World monkeys show a visual polymorphism, characterized by obligatory male dichromacy. The ecological role of this genetic difference still remains unclear, but some studies show that dichromats and trichromats appear to have different abilities in detecting colored targets against a background of leaves. The Cerrado's marmoset (Callithrix penicillata) is known to forage in brightly illuminated (savanna-like vegetation) and dimly illuminated (forests) environments, exploiting a high amount of dark fruits. Hence, it seems to be a good model for studying the differential advantages enjoyed by each color vision phenotype under natural conditions. Our aim was to verify how the different phenotypes of Cerrado's marmoset detect components of their diet, evaluating the existence of differential phenotype advantages. Under two different light conditions, visual signals of naturally consumed fruits were modeled against different backgrounds scenarios. Even though dichromats and trichromats appear to be equally suited for tasks involving fruit detection, phenotype differential advantages are observed in this marmoset. In many conditions trichromats are predicted to perform better than dichromats, but under low ambient light dichromats manage to outperform trichromats in some scenarios. Phenotypes that carry widely spaced and longer M/L pigments enjoy the most advantage. These differential performances of trichromatic phenotypes, together with overdominance selection, seem to explain the maintenance of the tri-allelic system found in callitrichids.

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.

“…Trabalhos anteriores apontam que proporções de forrageio ou consumo de frutos e exsudatos dependem de condições ambientais que determinam a disponibilidade destes recursos (RYLANDS;FARIA, 1993;VILELA;FARIA, 2004;CASTRO;ARAÚJO, 2006VILELA, 2007ZAGO, 2012). Os porcentuais de registros encontrados para cada categoria alimentar amostradas neste trabalho corroboram com estas informações.…”

ResumoEspécies do gênero Callithrix foram introduzidas em diferentes regiões do Brasil e suas adaptações alimentares podem ser fatores que possibilitam seus estabelecimentos nesses ambientes. Este estudo objetiva determinar atividades alimentares e recursos vegetais utilizados na dieta de Callithrix penicillata introduzidos em um fragmento florestal urbano na Ilha de Santa Catarina. No Parque Ecológico do Córrego Grande (PECG) foram monitorados três grupos de C. penicillata em duas fases de seis meses. Os itens alimentares consumidos foram registrados em amostragens mensais de um dia para dois grupos e dois dias para outro grupo. Para o grupo amostrado por dois dias mensais também foram registradas as atividades alimentares. A atividade predominante foi Presa Animal com 70% dos registros, seguida por Exsudato, com 16%, Fruto, com 8% e Suplementar, com 5%. A família Fabaceae foi mais expressiva para exploração de Exsudato e Myrtaceae, para Fruto. Os resultados encontrados são semelhantes aos de distribuições originais de Callithrix. Dentre essas semelhanças foram encontradas espécies vegetais registradas em suas dietas. A disponibilidade desses vegetais associada à preferência de C. penicillata por hábitats fragmentados e a disponibilidade de alimentos fornecidos por seres humanos são fatores que parecem possibilitar o estabelecimento dessa espécie no PECG.
