“…While the majority of camera trap research uses photographs, video footage may be more suitable for applications such as behavioural studies (Caravaggi et al., 2017; Janisch et al., 2021; Tagg et al., 2018), monitoring group size (Balestrieri et al., 2016; Green‐Barber & Old, 2018; Medeiros et al., 2019) or density estimation of unmarked species (Corlatti et al., 2020; Howe et al., 2017; Nakashima et al., 2018). Video footage may also increase public engagement and facilitate easier identification of species and individuals for citizen scientists (Reyes et al., 2017; Swinnen et al., 2014).…”

Camera traps are increasingly used in wildlife monitoring and citizen science to address an array of ecological questions on a wide variety of species. However, despite the ability of modern camera traps to capture high-quality video, the majority of studies collect still images, in part because of concerns with video performance. We conducted a camera trap survey of a forested landscape in the UK, using a grid of paired camera traps, to quantify the impact of using video compared to photos on the outcomes of ecological research and for participation and engagement of citizen scientists. Ecological outputs showed no difference between photo and video datasets, but comparison between expert and citizen science classifications showed citizen scientists were able to classify videos more accurately (average accuracy of 95% for video, 86% for photo). Furthermore, citizen scientists were more likely to volunteer additional information on age (provided for 61% videos and 30% photos) and sex (provided for 63% videos and 45% photos) of animals in video footage. Concerns over slow trigger speeds for videos did not appear to affect our datasets or the inferences gained. When combined with citizen science, video datasets are likely to be of higher quality due to increased classification accuracy. Consequently, we encourage researchers to consider the use of video for future camera-trapping projects.

“…Sapajus flavius occurs in the Atlantic Forest and Caatinga of north-east Brazil (Martins et al, 2016; Valença Montenegro et al, 2020). This species has a generalist diet (de Souza & Ferreira, 2019; Medeiros et al, 2019) and is categorized as Endangered on the IUCN Red List because of habitat loss and fragmentation resulting from coastal development and sugar cane plantations (Valença Montenegro et al, 2020). It is recognized as one of the most threatened primates globally (Mittermeier et al, 2012), although it is no longer included in the list of the top 25 most endangered primate species (Schwitzer et al, 2019).…”

Brazil has a high diversity of primates, but increasing anthropogenic pressures and climate change could influence forest cover in the country and cause future changes in the distribution of primate populations. Here we aim to assess the long-term suitability of habitats for the conservation of three threatened Brazilian primates (Alouatta belzebul, Sapajus flavius and Sapajus libidinosus) through (1) estimating their current and future distributions using species distribution models, (2) evaluating how much of the areas projected to be suitable is represented within protected areas and priority areas for biodiversity conservation, and (3) assessing the extent of remaining forest cover in areas predicted to be suitable for these species. We found that 88% of the suitable areas are outside protected areas and only 24% are located in areas with forest cover. Although not within protected areas, 27% of the climatically suitable areas are considered priority areas for conservation. Future projections, considering a severe climate change scenario, indicate that A. belzebul, S. flavius and S. libidinosus may lose up to 94, 98 and 54% of their suitable range, respectively. The establishment of primate populations and their long-term survival in these areas are at risk. Mitigation actions such as the implementation of new protected areas, forest restoration and reduction of greenhouse gas emissions will be essential for the conservation of Brazilian primates.

“…As espécies do gênero Sapajus ocorrem na Floresta Amazônica, Caatinga, Cerrado e Floresta Atlântica (Freese e Oppenheimer, 1981). Suas distribuições estendem-se até o sul do Paraguai e norte da Argentina (Lynch Alfarro et al, 2012), possuem tamanho médio e corpo robusto, têm hábito diurno e preferencialmente arborícola (Fragaszy et al, 2004), consomem frutos, folhas, flores, néctar/seiva, casca de árvores, sementes, raízes, brotos, pedúnculos, cultivos agrícolas, mel, artrópodes, gastrópodes, ovos de aves, pequenos vertebrados, ostras e caranguejos em regiões costeiras (Valença-Montenegro, 2011;Rodrigues, 2013;Silva, 2019;Medeiros et al, 2019). Várias espécies do gênero apresentam capacidade extra de forrageio, utilização de ferramentas e acesso a itens alimentares encapsulados ou subterrâneos (Souto et al, 2011;Lacerda, 2013;Liebsch e Mikich, 2015;Bacalhão et al, 2016).…”

A fragmentação florestal e a perda de habitat provocam mudanças na estrutura da paisagem e alterações no padrão de atividades das espécies. A presente pesquisa teve o objetivo de determinar os parâmetros estruturais e funcionais das classes de paisagem utilizadas pelo macaco-prego-galego, Sapajus flavius. As classes de paisagem floresta, plantações de cana-de-açúcar e pomares foram digitalizadas em tela no software Qgis (versão 2.18.0), utilizando a imagem do Google Earth Pro, bem como foram calculadas as distâncias que os indivíduos adentraram nas plantações de cana-de-açúcar. As métricas foram calculadas na extensão V-late do software ArcGis, versão 10.3, e as métricas de conectividade foram calculadas no software Fragstats 4.2. Foram delimitadas as classes de paisagem, registrada a frequência das visitas e monitorados os tipos de usos (alimentação, deslocamento e coleta de cana-de-açúcar e/ou frutos) pelos indivíduos. A classe floresta mediu aproximadamente 2.657,8 ha, as plantações de cana-de-açúcar 5.s202,9 ha e os pomares, 0,92 ha. A análise das métricas de paisagem evidenciou a fragmentação da classe floresta e a baixa permeabilidade da matriz formada pelas plantações de cana-de-açúcar, pois a distância máxima que os indivíduos adentraram nas plantações foi de 20 metros. A matriz funciona como complementação de hábitat, sendo a classe de paisagem mais visitada. Nas plantações de cana-de-açúcar os indivíduos coletaram a cana; nos pomares coletaram frutos e na floresta consumiram cana-de-açúcar e frutos nativos e exóticos. A matriz, formada por plantações de cana-de-açúcar, não foi utilizada pelos indivíduos no deslocamento para outros fragmentos de floresta. Os dados reforçam a importância da criação de corredores de vegetação nativa, aumentando a conectividade da paisagem, permitindo o deslocamento dos indivíduos e contribuindo para conservação da espécie.
