Medium- and large-sized mammals from Estação Biológica Fiocruz Mata Atlântica, Rio de Janeiro, south-eastern Brazil

The Pedra Branca Forest is in a highly urbanised region of the central portion of Rio de Janeiro City and comprises the largest urban forest in the world (> 12,000 ha). The local flora and fauna are protected by three conservation units and the Estação Biológica Fiocruz Mata Atlântica (EFMA), which comprises 462 hectares on the east side of the remnant. The local biodiversity is still little known compared to other Atlantic Forest remnants from the Rio de Janeiro State. Here, we provide results of a survey of medium- and large-sized terrestrial mammals from the EFMA. In addition, we analysed the distribution of this fauna along three habitat types defined as Peridomicile, Transitional Forest and Forest Core. Sampling was performed from 2017 to 2020 and comprised a camera-trap survey, interviews with residents and local workers and occasional records. Results include occurrence records for 16 autochthonous and one allochthonous (Callithrix sp.) wild mammals, which are distributed into 14 families and seven orders, in addition to the presence of free-ranging domestic dogs and cats. Four species are in some category of threat of extinction at national or global levels. Amongst them, Leontopithecusrosalia (first record for the Rio de Janeiro City in more than a century) and Leopardusguttulus are classified as Vulnerable by IUCN. Most wild native species were registered in the three habitat types, but with differences in the frequency of records. Our results indicate that the presence of domestic dogs and cats influenced the species composition in each area, with Nasuanasua, Dasyproctaleporina and Didelphisaurita less frequent in places where domestic dogs and cats are more frequent. This is the first systematic effort to understand the occurrence and distribution of mid- and large-sized mammals in the Pedra Branca Forest.

Beloved Whiskers: Management Type, Care Practices and Connections to Welfare in Domestic Cats

Simple Summary

Little is known about the differences between indoor and outdoor cat management practices. Thus, our study investigated whether Brazilian cat owners’ management types were related to other cat care practices, the quality of human-animal interactions and cat welfare. We used social networks to distribute an online survey to cat owners. This survey included questions regarding owners’ sociodemographic data, type of management applied, cat care practices, and cat health and behavioral problems, as possible consequences of the management type. A total of 16,302 cat owners responded. Most (74.78%) owners reported providing indoor management for their cats; this corresponded to owners who lived in apartments and provided more cat care practices and interactions with their pets. Outdoor management was related to cats residing in farms or houses, sleeping outdoors, and having less interaction with their owners. We concluded that owners practicing indoor management were more likely to be closer to their cats than those reporting outdoor management, suggesting that the former may have more advantages related to closer human-animal relationships. It was noted, however, that indoor management was associated with obesity and owner-reported behavioral problems.

Abstract

The quality of cat care practices depends in part on the type of management applied, which either positively or negatively impacts cat welfare. This study investigated whether the type of cat management (indoor vs. outdoor) was related to other cat care practices adopted by cat owners, associated with the quality of human-cat relationships and cat welfare. An online survey was distributed via social networks. Descriptive statistics, categorical Principal Component Analysis, Fisher’s Exact test and Chi-square test in contingency table were applied. A total of 16,302 cat owners returned the survey. Most Brazilian owners reported indoor management of their cats; this was related to owners living in apartments, more frequent use of cat care practices, and more interactions with their pets. Outdoor management was related to cats living in houses or farms, sleeping outdoors or around the neighborhood, and owners had fewer interaction with their pets. In conclusion, owners practicing indoor management seemed to be closer to their cats than owners reporting outdoor management. However, obesity and owner-reported behavioral problems were associated with indoor management.
