“…Additionally, the widespread deforestation of the Atlantic Forest (Ribeiro, Metzger, Martensen, Ponzoni, & Hirota, 2009) may act in synergy with future climate change, reducing the ability of species to adapt to that change (Hof, Levinsky, Araújo, & Rahbek, 2011). To top it all, the frequent and recent outbreaks of yellow fever in the Atlantic Forest (Moreno et al, 2011;Paules & Fauci, 2017) and its severe impacts on populations of primate species (Fialho et al, 2012;Holzmann et al, 2010;Moreno et al, 2015) worsen the situation of future conservation of endangered marmosets.…”

Aim Parapatric distributional patterns can arise from abiotic or biotic factors, or from dispersal barriers. Climate change can potentially affect parapatry by changing species’ potential geographic distribution, and thereby widening or shrinking contact zones. Here, we study the effects of climate change on all six species in the genus Callithrix, a group of small‐sized Neotropical primates that is distributed parapatrically in eastern Brazil, allegedly due to biotic interactions. Location Atlantic Forest, savanna and xeric shrublands from Brazil. Methods We explore a method to investigate potential effects of climate change on the distribution of parapatric species by (a) determining whether the parapatric pattern is explained by abiotic (climate) or biotic (species’ interactions) factors using niche equivalency and niche similarity tests; (b) estimating each species’ potential distribution under current and future climatic conditions, using ecological niche models; and (c) performing a pixel‐by‐pixel analysis in order to constrain distribution overlap between species pairs in which parapatry is maintained by biotic factors. Results We found that parapatry in Callithrix is maintained mostly by abiotic factors, except for two species pairs (Callithrix aurita vs. C. flaviceps and C. geoffroyi vs. C. penicillata) in which biotic factors are more likely to be acting. Our proposed method is able to produce better models than conventional ecological niche modelling, predicting net reductions in distribution area for some species and increases for others; however, reductions generally exceeded expansions. The reduction in potential distribution areas would maintain Callithrix flaviceps as Endangered under IUCN criteria. Main conclusions Despite range contractions and the loss of area of sympatry, climate change is unlikely to affect the parapatric distribution patterns in Callithrix, nor intensify interspecific interactions.

“…Nossos resultados confirmam a abundância reduzida da espécie no PNI, que por motivos desconhecidos ainda não conseguiu restabelecer sua população de maneira satisfatória, mesmo após mais de 70 anos do surto epizoótico que quase causou a extinção local (Ávila-Pires & Gouvêa 1977), similar ao registrado em outras áreas para a mesma espécie (Bicca-Marques & Freitas 2010, Fialho et al 2012). Isto aumentaria a chance de endogamia facilitando então a expressão de alelos recessivos que poderiam causar anomalia na coloração (Fortes & Bicca-Marques 2008), como a falta de pigmentação em todo o corpo, com exceção das extremidades, registrada aqui e conhecida como leucismo (Abreu et al 2013).…”

The occurrence of Alouatta guariba clamitans in the Itatiaia National Park (PNI) are considered rare. For over 70 years an epizootic outbreak of yellow fever almost caused the local extinction of this species and since then only one record by direct observation was obtained. In this study, records were obtained by direct observation of a group of four adults, one male and three females, and an infant in forest environment (ca. 1200m). One of the females presented anomaly in the coloration, characterized as leucism. A record of solitary adult male was held in high altitude grasslands (2450m). It is possible that the fault is related to the low density of the species, similar to that reported in other studies. The case record in high altitude, which can be considered the highest for primates in the country, suggests expanding the occurrence of possibilities and use area for the species. The monitoring of this species is to be continuously executed, including higher areas, in order to obtain accurate estimates of density. The performance of activities for its conservation, such as the translocation of individuals from surrounding areas to the PNI should be assessed, to avoid their possible local extinction.

“…The occurrence of an African lineage ZIKV in Southern Brazil, where the overall prevalence of Arbovirus infections in humans is believed to be low, elevates the importance of investigating circulating viruses with potential to adapt to human populations, since the cases 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 described here are not a spillback event from the Asian-related ZIKV currently circulating in humans. Alouatta guariba is highly susceptible to YFV, serving as a sentinel species indicating circulation of YFV 17,18 . The susceptibility of this species to ZIKV has not been described to date.…”

Mosquito borne flaviviruses cause a series of important diseases in humans and animals. These viruses are maintained in cycles involving replication in mosquito and in vertebrate hosts. Most natural hosts are vertebrate animals living in sylvatic or peridomestic environments. Human contact with these environments may result in host shifts that lead to the establishment of urban transmission cycles. Zika virus is a Flavivirus that persists in nature in a transmission cycle involving non-human primates (NHP). Its recent emergence in Brazil has shed light upon the importance of surveying this agent in Brazilian sylvatic environments. Here we present histopathological and molecular evidence that free ranging howler monkeys (Alouatta guariba) in Southern Brazil are infected by ZIKV closely related to African lineage MR766. Nine NHP were nested RT-PCR positive for ZIKV RNA. Sequence analysis revealed 96 to 98% identity to ZIKV MR766 and 85% identity to ZIKV P6-740, the current epidemic strain. The affected howler monkeys presented discrete inflammatory infiltrates in several tissues and immunohistochemichal (IHC) labeling of viral antigen was observed in placenta. These findings point to the circulation of African lineage Zika virus in the Americas in non-human primates. And raises the possibility that ZIKV was introduced into the Americas on more than one occasion. 1
