2017) Movement patterns and space use of the first giant anteater (Myrmecophagatridactyla) monitored in São Paulo State, Brazil, Studies on Neotropical Fauna and Environment, 52:1, 68-74, ABSTRACTThis study analyzes a giant anteater's (Myrmecophaga tridactyla) movement patterns and space use in São Paulo, Brazil. It is the first study to track a giant anteater with Iridium-GPS. The anteater traveled an average distance of 1326 m day -1 with an average speed of 1.04 m min -1 . Home range by Kernel was 2.46 km 2 while the core area was 0.75 km 2 , and estimates by Brownian bridge and minimum convex polygon were also provided. The anteater used shrub savanna, open savanna, and water habitats more than expected. Monitoring ended just after 10 days when the female giant anteater's GPS was found on an illegal trail. RESUMOEste estudo analisa os padrões de movimento e o uso do espaço por um tamanduá-bandeira (Myrmecophaga tridactyla) em São Paulo, Brasil. É o primeiro estudo a monitorar um tamanduábandeira com GPS-Iridium. O tamanduá-bandeira percorreu uma distância média de 1.326 m/dia com uma velocidade média de 1,04 m min -1 . A área de vida estimada por Kernel foi de 2,46 km 2 , enquanto a área núcleo foi de 0,75 km 2 . Estimativas por Ponte Browniana e Mínimo Polígono Convexo também foram fornecidas. O tamanduá-bandeira utilizou os hábitats savana arbustiva e aberta, e àqueles relacionados à água mais do que o esperado. O monitoramento terminou depois de 10 dias quando o GPS do tamanduá-bandeira foi encontrado caído em uma trilha ilegal. ARTICLE HISTORY

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal‐central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation‐related research. There are no copyright restrictions.

In ecological parks, the proximity to tourist activities facilitates the exploration of garbage by coatis, with possible serious consequences for the animals health . We described the contents of wild coatis feces from three ecological parks. After analyzing 62 samples, fragments of plants and animals were identified in all feces. In the feces of two parks, seeds were present between 36.4% and 48.6% of the samples. Arthropod fragments were identified in 100% of the samples from two parks, but only 87.3% in a third park. Scales, bones or bird feathers were present in some samples. Undigested material of industrial origin was detected in 34.3% to 54.5% of the samples, such as fragments of paper, string, plastic, aluminum, latex and glass. Results are in line with other studies on the diet of wild coatis, but the intake of foreign bodies, potentially harmful to health, is described for the first time. Clinical problems resulting from ingesting waste can be dental fractures, mucosal erosions, intestinal perforation, peritonitis, impaction, diarrhea, weight loss, intoxication and infections. Coatis in the three parks are at risk of health, and actions are needed to avoid clinical and potentially fatal problems. Four actions are recommended to avoid ingesting foreign bodies: increasing the environmental education of visitors; improving the storage of waste generated in parks; periodically monitor the health of coatis, in order to make interventions when possible; make a permanent program to study the ecology of species in the three parks.

Wild animals that feed on garbage waste are a problem in ecological parks as it can substantially alter their food ecology. Wild coatis that occupy human recreation areas in parks are often observed feeding on garbage, but the ecological consequences are scarcely known. Forty-four fecal samples from females and 12 from males of wild coatis living in two ecological parks (Parque Municipal das Mangabeiras (PMM) and Parque Nacional do Caparaó (PNC)) were analyzed. Multivariate statistics were applied to evaluate the interaction between four variables (fecal volume, composition, place and sex of coatis). A significant interaction between the parks and sexes with regard to volume and food category was not found. Ungrouped analysis allowed for the identification of a decreasing gradient in volume from PNC males, followed by PNC females, PMM males, and PMM females. We did not find differences between categories of food between males and females from PNC and PMM, except for invertebrates. Females from PNC consumed more invertebrates than males and females of PMM, but we did not find differences from PNC males. The coatis of both parks primarily consume invertebrates and vegetables, but garbage residues were found in their feces. Garbage fragments, such as paper, glass, metal, plastic and rope, cause a risk to the health, compromising the conservation efforts of wild coatis. Actions are needed to prevent the access of coatis to dumps in both parks.

The tayra (Eira barbara) is a common and broadly distributed Neotropical carnivore, yet is not well-studied. While this species is apparently associated with forested habitats, it also appears tolerant of some anthropogenic disturbance. We deployed 57 unbaited camera traps (n = 4923 trap-days) in and around a protected area (Furnas do Bom Jesus State Park, São Paulo, Brazil) to survey for tayra and two potentially interactive species: puma (Puma concolor) and free-ranging dogs (Canis familiaris).We used encounter histories generated from photographs and occupancy models to quantify tayra landscape use in the human-dominated landscape composed of the protected area that was near a city and surrounded by agricultural lands dominated by small farms. We fit co-occurrence models to understand whether puma and freeranging dogs affected landscape use by tayra. We detected tayra at 44% of sites and found that tayra landscape use increased with the proportion of forest cover within 500 m of the sampling site. Other factors predicting tayra landscape use included whether the sampling site was within the protected area, its distance to water, and slope. Dogs, which are common on the periphery of the protected area, seem to have a weak negative effect on tayra landscape use. Because of the concentration of forest within the park, this is an important protected area for the carnivore population within this human-modified landscape. Thus, environmental variables, such as forest cover, distance to water, as well as administrative protection status, are important for understanding local-scale tayra distribution.

Gigantorhynchus echinodiscus (Diesing, 1851) is a parasite of anteaters in South America. Although described by Diesing in 1851, there is still a lack of taxonomic and phylogenetic information regarding this species. In the present study, we redescribe G. echinodiscus collected from a giant anteater, Myrmecophaga tridactyla Linnaeus, 1758, from the Brazilian Cerrado (Savannah) in the State of São Paulo by light and scanning electron microscopy. In addition, phylogenies were inferred from partial DNA gene sequence of the nuclear large subunit ribosomal RNA gene (28S rRNA). We provide for the first time details of the proboscis with a crown having 18 large hooks and numerous small hooks, a lateral papilla at the base of the proboscis, a ringed pseudo-segmented body, large testes, cemented glands in pairs, and a non-segmented region in the posterior end of the body, which contributed to the diagnosis of the species. Molecular phylogenetic analyses recovered G. echinodiscus forming a well-supported monophyletic group with Mediorhynchus sp., which was congruent with morphological studies that allocate both genera within the family Gigantorhynchidae. In conclusion, the present work adds new morphological and molecular information, emphasizing the importance of adopting integrative taxonomic approaches in studies of Acanthocephala.
