Small mammals in the diet of barn owls, Tyto alba (Aves: Strigiformes) along the mid-Araguaia river in central Brazil
Owls from the riverbanks at Fazenda Santa Fe had a more diverse diet, preying mainly on rodents that typically inhabit riparian grasslands and forests - Hylaeamys megacephalus and Oecomys spp.
The Araguaia River as an Important Biogeographical Divide for Didelphid Marsupials in Central Brazil.
It is hypothesized that the role of the Araguaia as a riverine barrier is linked to the level of ecological specialization among the 6 didelphid species and differences in their ability to cross rivers or disperse through the associated habitat types.
Small mammals of the mid-Araguaia River in central Brazil, with the description of a new species of climbing rat
A new species of Rhipidomys is described previously assigned to R. nitela, which is apparently endemic to the AraguaiaTocantins basin in the Cerrado.
From north to south and back: the role of the Balkans and other southern peninsulas in the recolonization of Europe by wild boar
Wild boar from the Balkans exhibited high genetic diversity and the existence of population structuring, revealing two groups: Continental Balkans and South Balkans, and all three peninsulas played a similar role in the post-glacial recolonization of Europe by wild boar.
Pipe refuge occupancy by herpetofauna in the Amazonia/Cerrado ecotone
We evaluated the usefulness of arboreal pipe refuges for studying Neotropical herpetofauna, by quantifying the effects of microhabitat variables and pipe colouration on pipe occupancy rates. We used
Evidence of neotropical anuran community disruption on rice crops: a multidimensional evaluation
It is shown that converting natural vegetation to irrigated rice crops drives many species to local extinction, and resilient species to exhibit lower body condition, and the importance of maintaining high diversity in anthropogenic environments is important for ecosystem resilience.
Paths for colonization or exodus? New insights from the brown bear (Ursus arctos) population of the Cantabrian Mountains
The results reveal the presence of two different mitochondrial (matrilineal) haplotypes in the Cantabrian population, both belonging to European brown bear clade 1a, and show that CanE is closer to the historical Pyrenean (Pyr) haplotype than to CanW.
Seasonally flooded stepping stones: emerging diversity of small mammal assemblage in the Amazonia-Cerrado ecotone, central Brazil
The results reinforce the idea that the habitat mosaic found in the Araguaia alluvial plain has an important role in promoting the high biodiversity of this area and that natural forest fragments may act as a refuge and food resource for several species.
