Acta Scientiarum: Biological Sciences, 2011 The objective of this study was to quantify argyrophillic, argentaffin and insulin immunoreactive endocrine cells in the different segments of the small intestine of Didelphis aurita and measure probable differences in the number of these cells between ...

Ecology and Evolution, 2023 Invasive buffel grass (Cenchrus ciliaris) is considered a threat to the critically endangered northern hairy‐nosed wombat (Lasiorhinus krefftii; NHW). Buffel grass outcompetes native grasses, reducing availability of native food items for NHW, and causes

Aerobic power, huddling and the efficiency of torpor in the South American marsupial, Dromiciops gliroides. [PDF]
, 2012 During periods of cold, small endotherms depend on a continuous supply of food and energy to maintain euthermic body temperature (T(b)), which can be challenging if food is limited. In these conditions, energy-saving strategies are critical to reduce the

Conservation Science and Practice, 2023 Ecological monitoring is crucial for tracking changes in the status of species over time. However, ensuring that monitoring programs possess adequate statistical power—capacity to detect changes in populations with a high level of confidence—remains a ...

Relative demographic susceptibility does not explain the extinction chronology of Sahul’s megafauna
eLife, 2021 The causes of Sahul’s megafauna extinctions remain uncertain, although several interacting factors were likely responsible. To examine the relative support for hypotheses regarding plausible ecological mechanisms underlying these extinctions, we ...

Shortest known prion protein allele in highly BSE-susceptible lemurs [PDF]
, 2000 We describe the shortest prion protein allele known to date. Surprisingly, it is found as a polymorphism exactly in a species (prosimian lemurs) which seems highly susceptible to oral infection with BSE-derived prions. The truncation of the prion protein

Acta Scientiarum: Biological Sciences, 2013 Each kind of trap tends to be selective on species sampled, in a way that each one only reveals part of the abundance and species richness of the community sampled.

Corepressor diversification by alternative mRNA splicing is species specific. [PDF]
, 2016 BackgroundSMRT and NCoR are corepressor paralogs that help mediate transcriptional repression by a variety of transcription factors, including the nuclear hormone receptors.

Marsupial-specific microRNAs evolved from marsupial-specific transposable elements [PDF]
Gene, 2009 Using a direct miRNA cloning strategy we previously identified fourteen marsupial- or species-specific microRNAs in the marsupial species Monodelphis domestica. In the present study we examined each of the pre-miRNAs and their flanking sequences and demonstrate that half of these miRNAs evolved from marsupial-specific transposable elements.
