Guidelines and considerations for capturing and collaring wild primates: a case study with capuchin monkeys (Sapajus nigritus cucullatus).

Many aspects of the ecology, evolution and social behavior of wild-living primates remain un-explored and require further investigation. While long-term field studies are crucial for addressing conservation concerns for many primates' species, acquiring the necessary data is often challenging, often due to difficulties in locating study groups. Radio-telemetry has significantly facilitated the study of primates and other animals living in tropical forests. However, there are important practical challenges in the process of capturing and releasing animals after placement of telemetry collars. In this study, we report guidelines and considerations for capturing and collaring wild capuchin monkeys, Sapajus nigritus cucullatus, in the Atlantic Forest of Argentina. Our ultimate goal is to contribute to making captures safer, preventing harm and stress to animals when using radio-telemetry in monitoring strategies for conservation of this primate species. These methods can be useful for researchers using field capture and radio-telemetry for monitoring groups or populations of wild primates, specifically wild Sapajus.

A rare case of ectopic dioctophymosis in Leopardus pardalis (Carnivora, Felidae) in Paraguay.

An adult female Leopardus pardalis from Jardín Botánico y Zoológico de Asunción, Paraguay was brought in from the wild, and inspected for a parasitic structure attached to the vulva. The parasite was removed and was identified as a Dioctophyme renale female. Blood samples and ultrasound did not show abnormalities in any organ, confirming the ectopic presentation of the parasite. This is the first report of D. renale in the L. pardalis and a first time for ectopic location in vagina and spontaneous elimination in a felid.

Tunga penetrans in Giant anteater (Myrmecophaga tridactyla) from Argentina.

Tunga penetrans (Siphonaptera, Tungidae) is a flea that infests humans and a variety of domestic and wild animals. Burrowing of the female flea under the skin causes tungiasis, a disease that manifests in skin lesions that if untreated, can progress to severe complications. In this paper, we report the first case of T. penetrans in a wild giant anteater (Myrmecophaga tridactyla) from Argentina. We describe the lesions and discuss the potential role of the giant anteater as a host or reservoir for this flea.

Pelecitus tercostatus (Molin, 1960) (Nematoda, Onchocercidae) in Amazona vinacea (Aves, Psittaciformes) from Argentina: morphological details and clinical findings.

Pelecitus tercostatus (Molin, 1860) (Onchocercidae, Dirofilariinae) was found in the leg of a Vinaceous-breasted Parrot Amazona vinacea (Aves, Psittaciformes) from Misiones, Argentina. The present report enlarges the host distribution of the species and represents the first record of any nematode in A. vinacea. The macroscopic lesions produced in the bird are also described.
