“…Approximately 9,000 ants can be consumed per day by an anteater (Macdonald 2007), depending on their habitat and also their state of preservation (Leal et al 1993, Lopes et al 2010, Suguituru et al 2013. Despite this large amount, in many studies only 10% of the stomach contents available for analysis are used, leaving other food items, such as ants and other arthropods (Reis-Filho et al 2007, Gallo et al 2017. In this present study, we used all available content in the eight samples, where we found 16 species and 26 morphospecies of ants identified in genus and 17 other morphospecies belonging to other orders.…”

“…Tamandua tetradactyla is a common species in all Brazilian biomes (Desbiez and Medri 2010). It is one of the most frequently roadkilled animals in southeastern Brazil, and studies of the impacts caused by the road network and resident fauna have enabled access to previously unavailable data (Bernegossi et al 2018), such parasites (Pinheiro et al 2018), diseases (Muñoz-García et al 2018), and food preferences (Gallo et al 2017) . The analysis of contents in the digestive system of roadkilled animals shows how carcasses can be used to generate information on the biology and feeding habits of this species.…”

The Collared Anteater, Tamandua tetradactyla (Linnaeus, 1758), is a small mammal predator of ants. There are few studies describing which species are in fact consumed by them. This study was aimed to investigate the diversity and abundance of local species of ants preyed by the T. tetradactyla. Eight samples of stomach contents collected in the period from 2009 to 2014 were analyzed and identified at the lowest possible taxonomic level. We found 5,906 ants distributed in 16 species. The most abundant samples were number 2 and 4 with almost 2,000 individuals and the highest richness and abundance was Myrmicinae subfamily with eight species and 3,721 individuals. The ant richness found in this research demonstrates that the anteaters are generalists and opportunistic about their diet, not having a preference for a particular species, but rather for those insects that are available in their habitat.

“…Nonetheless, this guild needs coverage of gallery and riparian forest, due to their dependency on this kind of habitats for thermoregulation (Camilo-Alves & Mourão, 2006), resting (Mourão & Medri, 2007), and finding food resources in the arboreal insect nests (Montgomery & Lubin, 1977). Mammalian terrestrial insectivores have a key role in topdown effects on their prey on the ground as well on trees and lianas (e.g., termites, ants, bees) (Gallo et al, 2017;Hirsch et al, 2014). Therefore, conservation of this guild is important to regulate trophic interactions in savanna ecosystems.…”

Structural differences in mammal assemblages between savanna ecosystems of the Colombian Llanos

et al. 2019

The Colombian Orinoquia region is characterized by a high diversity of mammals, which is associated with complex ecosystems that include large extensions of Neotropical savannas (known locally as “Llanos Orientales”). Despite accelerated anthropogenic transformations in savanna ecosystems, the knowledge to design effective conservation strategies, such as the distribution of mammal assemblages, is still lacking for this region. In this paper, we evaluate if assemblages of medium and large mammals (i.e., species richness, relative abundance and the contribution of the different trophic guilds) are homogeneous across the Colombian Llanos by comparing three savanna ecosystems: floodplains savannas associated with an Andean river, aeolian floodplains savannas and highland savannas. After a sampling effort of 3,150 camera trap/days, we recorded 16 mammal species from the three savanna ecosystems. We compared the three assemblages and their constituent trophic guilds by ANOSIM and SIMPER non-parametric permutation tests. The three assemblages differed in composition, structure and trophic guilds. The floodplains savannas, associated to an Andean river, present the highest diversity, contrastingly, the high-plain associated with the Guyanese Shield presents the lowest diversity. This pattern could be explained due to the greatest floristic diversity, complex vegetation structure and more fertile soils present in the riparian forests of the floodplains savannas, despite being the most anthropogenically transformed. The carnivores were the most variable category and herbivores were the most abundant. Our results show that the diversity of medium and large mammals is heterogeneously distributed in the Colombian Llanos. Therefore, it is necessary to implement targeted conservation strategies according to the characteristics, local fragility of each ecosystem in the territory and each species response by local conditions.

“…Feeding can occur on the ground or on trees and consists of termites, ants, honey and bees (Medri et al 2006;Smith 2007;Miranda et al 2014;Gallo et al 2017). The collared anteater has a well-developed sense of smell that assists in locating food and compensates for poor vision and hearing (Smith 2007;Miranda 2014).…”

Evaluation of collared anteaters (Tamandua tetradactyla) presented in a wildlife health reference center of São Paulo state, Brazil

Deforestation and road construction have inflicted negative effects on wildlife populations. To contribute to the comprehension and preservation of wildlife species, this study aimed to evaluate collared anteater presented to a reference center located in São Paulo state, Brazil. Furthermore, the locations where the animals were most frequently found were determined. Data on collared anteaters (Tamandua tetradactyla) examined at the Center for Medicine and Research in Wild Animals (CEMPAS) were evaluated retrospectively for a period of 13 years. A total of 46 collared anteaters was examined, comprised of 14 males, 10 females, and 22 without identifying information. On average, adult males weigh 4.41 kg while adult females weigh 4.95 kg. The most common admission circumstance was vehicular strikes (36.96%), followed by dog bites (21.74%); 23.91% were considered clinically healthy. Animal outcomes were 36.96% (n=17) reintroduced, 34.78% (n=16) fatalities, 15.22% (n=7) transferred to other institutions, and 6.52% (n=3) escaped from the enclosure; and 6.52% (n=3) presented no medical record information. The collared anteaters were found mainly in the municipal areas of Botucatu (21.73%), São Manuel (17.39%), Lençóis Paulista (6.52%), and Bauru (4.34%), with SP-300 being the main highway associated with the occurrences. In conclusion, the main cause of lesion in the collared anteaters evaluated in this study was vehicular strike that that led to death. However, including all collared anteaters at least half of them had a positive outcome. Keywords:Wild animal, highway, clinical evolution, anteater.
