“…Cebus libidinosus is endemic to the Cerrado and the Caatinga, and has been recorded in the Brazilian states of Bahia, Ceará, Goiás, Maranhão, Minas Gerais, Paraíba, Piauí, Pernambuco, Rio Grande do Norte, São Paulo, Tocantins, and Distrito Federal (Pontes et al 2006, Vilela 2007, Canale et al 2009, Bruna et al 2010, Lynch-Alfaro et al 2012a, 2014, Feijó and Langguth 2013, Fragaszy et al 2013, Gomes et al 2015, Mendes et al 2015, Nova et al 2015). …”

“…We regard libidinosus as a member of the genus Cebus , subgenus Sapajus, and advocate for the use of the name Sapajus at the subgenus-level (contra Lynch-Alfaro et al 2012a, 2012b, 2014). The division between the gracile (untufted) and robust (tufted) groups of capuchin monkeys has been known for over a century (see Elliot 1913, Hershkovitz 1949, 1955), and the names Cebus and Sapajus have been applied to them at the subgenus-level, respectively (e.g., Silva-Junior 2001, Ferreira et al 2009, Casado et al 2010).…”

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published lists -e.g., excluding nominal taxa whose statuses as species have been claimed only on the basis of unpublished data, incomplete taxonomic work, or weak evidence.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

“…Panama is also an important biogeographic corridor in the evolution of Cebus , yet there is a dearth of Cebus genetic samples from areas outside of the canal zone. Comparing genetic samples from Coiba National Park to more samples across the Panamanian mainland will help clarify whether Pacific capuchins should be considered a separate species ( C. imitator ) from their Atlantic congeners ( C. capucinus ) [16,45,132]. …”

“…It is also possible that differences in tool use rates might be influenced by ranging patterns. Gracile capuchins have larger home ranges than robust capuchins, on average (reviewed in [45,77]), and thus might be able to access a more diverse set of food items that do not require tool use compared to robust capuchins. However, it is also possible that groups of robust capuchins are just more capable of extracting resources out of a smaller area due to morphological specializations such as thicker enamel and larger molars [16].…”

Habitual stone-tool-aided extractive foraging in white-faced capuchins,Cebus capucinus

et al. 2018

Habitual reliance on tool use is a marked behavioural difference between wild robust (genus Sapajus) and gracile (genus Cebus) capuchin monkeys. Despite being well studied and having a rich repertoire of social and extractive foraging traditions, Cebus sp. rarely use tools and have never been observed using stone tools. By contrast, habitual tool use by Sapajus is widespread. We review theory and discuss factors which might explain these differences in patterns of tool use between Cebus and Sapajus. We then report the first case of habitual stone tool use in a gracile capuchin: a population of white-faced capuchins (Cebus capucinus imitator) in Coiba National Park, Panama who habitually rely on hammerstone and anvil tool use to access structurally protected food items in coastal areas including Terminalia catappa seeds, hermit crabs, marine snails, terrestrial crabs and other items. This behaviour has persisted on one island in Coiba National Park since at least 2004. From 1 year of camera trapping, we found that stone tool use is strongly male-biased. Of the 205 camera trap days where tool use was recorded, adult females were never observed to use stone tools, although they were frequently recorded at the sites and engaged in scrounging behaviour. Stone tool use occurs year-round in this population; over half of all identifiable individuals were observed participating. At the most active tool use site, 83.2% of days where capuchins were sighted corresponded with tool use. Capuchins inhabiting the Coiba archipelago are highly terrestrial, under decreased predation pressure and potentially experience resource limitation compared to mainland populations—three conditions considered important for the evolution of stone tool use. White-faced capuchin tool use in Coiba National Park thus offers unique opportunities to explore the ecological drivers and evolutionary underpinnings of stone tool use in a comparative within- and between-species context.

“…Therefore, they are here referred to as Sapajus sp. (LYNCH-ALFARO et al 2014). According to local people, these capuchins have lived there for 30 years, and are most likely introduced.…”
