Twelve generic names have been ascribed to the New World tamarins but all are currently placed in just one: Saguinus Hoffmannsegg, 1807. Based on geographical distributions, morphology, and pelage patterns coloration, they divided into six species groups: (1) nigricollis, (2) mystax, (3) midas, (4) inustus, (5) bicolor (6) oedipus. Molecular phylogenetic studies validated five of these groups; each distinct clades. inustus is embedded mystax group. Genetic show that sister other...

Em 2020, incêndios em vegetação queimaram aproximadamente 40 mil hectares e mataram 17 milhões de vertebrados. Esse evento catastrófico, caracterizado pelo comportamento extremo do fogo facilitado pela combinação matéria orgânica acumulada seca prolongada, evidenciou tanto a vulnerabilidade ecossistema pantaneiro frente aos sazonais quanto necessidade um entendimento mais amplo sobre seus possíveis efeitos na biodiversidade local nas dinâmicas ecossistêmicas. Este estudo explora dos...

Abstract Human‐wildlife coexistence as a concept and management objective has received increasing attention from researchers decision makers. The approach will benefit the recognition that, at broader scales, human‐wildlife interactions (HWI) are best understood managed collaboratively complex systems, that is, dynamic, non‐linear, emergent, adaptive and, therefore, unpredictable. We present planning process for provides platform collaboration between decision‐makers—and other stakeholders...

The persistent high deforestation rate and fragmentation of the Amazon forests are main threats to their biodiversity. To anticipate mitigate these threats, it is important understand predict how species respond rapidly changing landscape. short-eared dog Atelocynus microtis only Amazon-endemic canid one most understudied wild dogs worldwide. We investigated habitat associations on two spatial scales. First, we used largest record database ever compiled for in combination with distribution...

The Brazilian Biodiversity Monitoring Program (Monitora Program) is a long-term large-scale program aimed at monitoring the state of biodiversity and associated ecosystem services in protected areas (PAs) managed by Instituto Chico Mendes de Conservação da Biodiversidade (ICMBio). Encouraging qualified social participation one Monitora Program’s guiding principles. In this case study, we describe how citizen occurs various stages Program, including planning, data...

Abstract Although considered an evolutionary force responsible for shaping ecosystems and biodiversity, fires’ natural cycle is being altered by human activities, increasing the odds of destructive megafire events. Here, we show that forest type modulates responses terrestrial mammals, from species to assemblage level, a catastrophic in Brazilian Pantanal. We unraveled mammalian richness was higher 1 year after fire passage compared pre-fire condition, which can be attributed habitat...

Abstract The genus Saguinus comprises three principal clades that diverged in the Middle to Late Miocene. Their taxa are ecologically differentiated and allopatrically distributed. These were recently recognized as different genera, , Tamarinus Oedipomidas . In phylogenetic relationships among species/subspecies poorly understood. Thus, this study we present a comprehensive dated genomic phylogeny based on double digest restriction associated DNA for all known species subspecies of We also...

Brazil's only records of Pocock's olingo (Bassaricyon beddardi) are based on sightings from the northernmost state Roraima, where similar kinkajou (Potos flavus) was reported as absent. Our recent field work in region led to collection two specimens and several more observations kinkajous a complete lack evidence presence olingos. Furthermore, name used locally describe nocturnal procyonids previously treated olingos, gogó de sola, refers leathery bare throat patch that we believe be...

Abstract The helminth Echinococcus vogeliRausch & Bernstein, 1972 is a causative agent of Neotropical Echinococcosis, chronic zoonotic disease which endemic to the region. This parasite transmitted from bush dogs (Speothos venaticus) their prey, include lowland pacas (Cuniculus paca) and agoutis (Dasyprocta spp.). In Brazil, most human cases Echinococcosis have been recorded in Amazonian states Acre Pará, although few data are available on occurrence potential definitive or intermediate...
