“…Such reduced risk of monkey mortality leads to higher patch occupancy. This explanation is supported by the lower occurrence of brown howlers in habitat patches immersed in landscapes with more urban areas and more open areas (the second-and third-best predictors of the species' presence), which normally lack their food resources or arboreal refuges (but see [86,87]). On the other hand, our result may be influenced by the species' presence in the four medium-to-large forest patches of the RVSBP wildlife refuge, which consists partially of wetlands that may be misclassified as water by MapBiomas.…”

Habitat modification due to human activities threatens species survival. While some species can inhabit habitat patches in anthropogenic landscapes, their occurrence often depends on landscape structure. We assessed the effects of landscape structure on brown howler monkey (Alouatta guariba clamitans) occurrence in an urban scenario. We conducted censuses in 59 forest patches from 2014 to 2016 in Rio Grande do Sul State, Brazil. We evaluated patch occurrence (presence/absence) in response to landscape composition (forest cover, arboreal crops, urban areas, open areas, and water) and configuration (patch density), considering the scale of effect. Water, urban, and open areas were the most important predictors of howler presence. Their presence was notably higher in landscapes with more water, likely because these landscapes consist of rural areas with low urbanization, less farming, and relatively high forest cover. Presence of howlers was positively associated with forest cover and negatively related to urban areas, open areas, and arboreal crops. Resource scarcity and increased mortality risks from human pressures, such as domestic dog attacks, electrocution, and roadkill on these land covers may explain these relationships. We highlight the importance of conserving and increasing forest cover in anthropogenic landscapes to protect species reliant on forested habitats, like howler monkeys.

Primates are arboreal and semi‐arboreal species, highly dependent on vascular plants. Primate diets typically include plant parts, such as fruits and leaves. Knowledge of the most consumed items is essential for this highly threatened group, especially in the deforested and fragmented Atlantic Forest. Our aim was to synthesise the knowledge about food resources of Atlantic Forest primates. We investigated the temporal and spatial distribution of studies with information on diet, the main taxa recorded as food resources, and the parts of plants most consumed by these primates. We searched for published literature containing food resource records for primates in the Web of Science and screened Neotropical Primates volumes. 96% of the food records were from plants, mainly fruits (50%), leaves (31%) and flowers (14%). Most plant species, genera and families have few records. The families most recorded were Myrtaceae (n = 440) and Fabaceae (n = 392), and the genera were Eugenia (n = 123), Inga (n = 113), Ficus (n = 109) and Myrcia (n = 102). A few primate species with long‐standing conservation programs or population monitoring had the highest number of food resource records. Study sites generally cover only a small part of the geographic range of the primate species, indicating a geographic bias. Our findings highlight the scarcity of research on the Atlantic Forest primate diet, which is especially concerning for threatened species such as Callithrix aurita and Leontopithecus caissara, which only had natural history notes on food resources, and Sapajus robustus, which had no records. The information synthesised here can be useful for planning and executing more efficient Atlantic Forest restoration plans, considering the key plant species for the primate diet. We reinforce the need to conduct more research on the diets of Atlantic Forest primates, as this knowledge can contribute to the understanding of the plasticity and physiology of organisms.
