., MARINHO FILHO, J. Mammal richness and diversity in Serra do Facão region, Southeastern Goiás state, central Brazil. http://dx.doi.org/10.1590/1676-0611- BN-2015-0033 Abstract: At least 251 mammal species are recorded for the Brazilan cerrado, which, therefore, is the third richest Brazilian biome. Most mammal surveys in Brazilian cerrado result from studies performed opportunistically and in short time periods. The aims of the present study were (1) provide a checklist for the mammalian fauna based on a five-year sampling in Serra do Facão region, Southeastern Goiás state; (2) compare small non-flying mammals diversity in open and forest areas and (3) compare species diversity before and after the flood caused by a hydroelectric reservoir filling. The data was gathered in 19 sampling periods, from May 2008 to September 2013. We sampled open and forest habitats and captured non-flying small mammals with Sherman and Tomahawk live traps and pitfalls; bats were sampled with mist-nets; large mammals were recorded with camera traps, and by direct observations and track surveys in field. We found 20 species of small non-flying mammals, 10 species of bats and 33 species of larger mammals. Species diversity was greater for forest than open habitats, and was also greater before than after the complete reservoir filling. About 10% of the recorded species are included in the Brazilian official list of threatened species. The total richness represents 25% of all cerrado mammal fauna, highlighting the importance of this area for regional mammal fauna conservation.

Hairy-eared cerrado mouse Thalpomys lasiotis is an endemic species of the cerrado biome. It can be found in open habitats, but its distribution is patchy and population numbers are unknown. In this paper, we describe, for the first time, aspects related to the ecology and natural history of T. lasiotis, detailing demographic parameters such as population densities, reproduction, home range, and longevity of this endemic and rare species. We captured, marked, and recaptured 55 individuals of T. lasiotis in Águas Emendadas Ecological Station, located in the northeast of the Federal District, Brazil. We found significant differences on population numbers and densities between the dry and wet seasons. Densities and population numbers apparently are affected by the seasonality of food resources. Moreover, the breeding season is seasonal, and both males and females were reproductively active during the wet season. T. lasiotis showed a permanence time ranging from 2-9 months, which means that individuals can survive for at least 9 months in natural habitats. The home ranges of males and females of T. lasiotis were not significantly different. However, males have larger home ranges than females and the mean distance moved by males was higher than the distance moved by females, which is consistent with the hypothesis that males belonging to polygynous species tend to move greater distances to avoid agonistic encounters and to search sexual partners.

The interaction between animal movement and roads is pervasive, but little is known of the effects of the land-use patterns in roadside landscapes on roadkill events. Here, we compared wildlife roadkill along two road stretches that cross landscapes with different land-use patterns, including the presence of protected areas in Central Brazil.Sampling was conducted in 2017 and 2018 in two seasons (dry and rainy). We expected roadkill events to be more frequent bordering the protected area. Roadkill occurred more frequently in the rainy season in the unprotected landscape. Birds were most frequently recorded in the unprotected (44%, n = 76) than in the protected landscape (37%, n = 48). The least recorded group in the unprotected landscape was Squamata (11%, n = 18), while mammals were less detected in the protected landscape (14%, n = 18). Classes 'agriculture' and 'savanna' were related to amphibian roadkill numbers. For Squamata, we observed the effect of the presence of forests in the protected landscape.Bird roadkill was affected by protection level, while the presence of pasture and the level of protection explained mammal roadkill. Differences in roadkill patterns reinforce the need for long-term management of this source of mortality for the Cerrado fauna.
