“…Regardless of their feeding and behavioral relationship with man, cats may still display opportunistic predation behavior [2][3][4][5]. For this reason, cats have been indicated as one of the main causes of the decline of other species in different areas of the world [3][4][5][6][7][8][9][10][11][12]. Research has also highlighted the significant impact of predation by cats on native fauna, especially regarding birds in insular environments [8][9][10][11].…”

The domestic cat (Felis silvestris catus) is indicated as a threat to several native species in different regions where they occur, especially seabirds in insular environments. In this study, we present the results obtained through fecal analysis and identification of the remains of prey killed by domestic cats in a fishing village in an insular area of the Brazilian Atlantic Forest. Although several species of seabirds use the island either as a migratory route, residence, or for nesting, we did not detect their presence among the identified items. However, other species of birds, mainly Passeriformes, were found. This corresponded to less than 10% of the total of items identified as predated by domestic cats during the sampling period. We emphasize the importance of carrying out new studies, as well as evaluating measures to identify more sensitive species and preventing potential impacts caused by felines in forest remnants in Neotropical regions.

“…Indirect analyses of fecal samples found at the observation sites, small fragments of Styrofoam, aluminum foil, and plastics. They also found remnants of domestic foods, such as fragments of cooked chicken bones, beans and fruit seeds used in human food, which demonstrates the weakness of these animals to these inappropriate foraging spaces for exploitation [16]. And according to Sabbatini et al [49] and Guerrera et al [52], the food supply by the inhabitants of the fragment can cause an alteration, both in the eating and behavioral habits, as metabolic disorders or possible pathology, mainly by ingestion of industrialized foods, with high levels of fat and sugars, and can cause serious health problems, as well as behavioral changes, as reported for other mammalian species.…”

“…With the high rates of degradation of the remaining fragment and due to the proximity of the residences, the presence of wild animals close to the urban environment in becoming increasingly common. Several studies report the use of areas inhabited by or close to those used by humans by different wild species, including coatis, as well as the use of human waste as a food source [16][17][18][19][20][21][22][47][48][49][50][51].

“…However, the bibliographic record for the species is relatively scarce and recent, which makes the study of these animals of paramount importance [10]. They are animals of habits mainly diurnal, scansorial and omnivores, displaying a generalist diet [10][11][12][13][14][15][16]. In urban areas, they may eat remains of food deposited in dumps close to their area of activity or supplied by humans [16][17][18][19][20].…”

Wild Neighbors: Perception of Residents of the Environment of a Fragment of Atlantic Forest in Urban Areas on the Presence and Approximation of Coatis (Nasua nasua)

Coatis (Nasua nasua) are often found in the forest areas, but are also adaptable to small urban fragments. This may represent disorders and problems with living with human populations. Here, we showed the residents' perceptions, recorded through questionnaires, about the coati's approximation to urban areas, in the margin of a remnant fragment of Atlantic forest. Of interviewees, 66.23% did not attribute the coati's visitation to risk or considerable problems. Among those interviewed 80.52% offered food to the animals. They have also reported the coatis exploiting solid waste deposits. We reported a few isolated cases involving negative interactions between coatis and humans or domestic animals. Although we verified a positive outlook by the population to this interaction, there are several risks arising from the approach of these animals. We need to develop environmental education strategies to the population close to the forest fragment, as well as in-depth studies to verify and reduce such risks.

Dietary ecology and its relationship with both muscle architecture and bite force potential has been studied in many mammalian (and non‐mammalian) taxa. However, despite the diversity of dietary niches that characterizes the superfamily Musteloidea, the masticatory muscle fiber architecture of its members has yet to be investigated anatomically. In this study, we present myological data from the jaw adductors in combination with biomechanical data derived from craniomandibular measurements for 17 species representing all four families (Ailuridae, Mephitidae, Mustelidae, and Procyonidae) of Musteloid. These data are combined to calculate bite force potential at each of three bite points along the dental row. Across our sample as a whole, masticatory muscle mass scaled with isometry or slight positive allometry against both body mass and skull size (measured via a cranial geometric mean). Total jaw adductor physiological cross‐sectional area scaled with positive allometry against both body mass and skull size, while weighted fiber length scaled with negative allometry. From a dietary perspective, fiber length is strongly correlated with dietary size such that taxa that exploit larger foods demonstrated myological adaptations toward gape maximization. However, no consistent relationship between bite force potential and dietary mechanical resistance was observed. These trends confirm previous findings observed within the carnivoran family Felidae (as well as within primates), suggesting that the mechanisms by which masticatory anatomy adapts to dietary ecology may be more universally consistent than previously recognized.
