Wildlife is imperiled in peri-urban landscapes: threats to arboreal mammals

Radiographically guided femoral neck osteosynthesis with cannulated compressive titanium screw and anti‐rotational component in a Brown Howler Monkey (Alouatta guariba clamitans)

“…These events can result in soft tissue injuries and fractures. 2 In small animal practice, femoral head and neck (FHN) fractures commonly result from feline proximal femoral epiphysiolysis, 3 avascular necrosis of the femoral head, and trauma, 4 and the treatments include FHN ostectomy, hip replacement, 5 and osteosynthesis with metallic implants. 6 Femoral head and neck ostectomy has already been reported in Rhesus macaque for treatment of osteoarthritis 7,8 ; however, to the best of our knowledge, there is no description of FHN osteosynthesis in non-human primates.…”

“…The destruction of their natural habitats imposed by human activities increases the species' susceptibility to traumatic events, including electrocution, dog attack, human mistreatments, and vehicle collision. These events can result in soft tissue injuries and fractures 2 …”

Mediastinal T‐cell lymphoma in a free‐ranging brown howler monkey (Alouatta guariba clamitans)

“…3,4 However, the neoplastic process and esophageal dilation/esophagitis should contribute to emaciation and a decline in the general state of the monkey, and walking on the ground makes it easy to attack. 19,20 Dog bites represent one of the leading causes of death of brown howler monkeys in urban-rural interface areas in the Atlantic Forest biome. 19,20 This is the first record of lymphoma associated with esophageal dilation in NHPs.…”

“…19,20 Dog bites represent one of the leading causes of death of brown howler monkeys in urban-rural interface areas in the Atlantic Forest biome. 19,20 This is the first record of lymphoma associated with esophageal dilation in NHPs. Therefore, the description of the present case can help in the differential diagnosis of neoplasms and esophageal lesions among captive or free-ranging NHPs.…”

Observations on the diet of Aotus nigriceps (Primates: Cebidae) in an urban and peri-urban area in Rondônia state, Brazil

“…The exploitation of peri-urban environments and isolation in urban environments can expose primates to different risks, such as electrocution, attack by domestic animals, vehicle collision, zoonosis and anthropozoonosis, and abuse/conflict with humans (Montilla et al 2020;Chaves et al 2022). In the city of Porto Velho, attempted predation of the primate Mico rondoni by a domestic cat was recorded (Oliveira & Fernandes 2021), demonstrating the potential threat to primates, including Aotus nigriceps.…”
