<p><em>A research consortium led by scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) provide evidence that social behaviour and social status are reflected at the molecular level of gene activation (epigenome) in juvenile and adult free-ranging spotted hyenas. They analysed non-invasively collected gut epithelium samples from both high-ranking and low-ranking female hyenas and showed that rank differences were associated with epigenetic signatures of social inequality, i.e., the pattern of activation or switching off of genes that regulate important...
<p>A new meta-analysis across six continents establishes that wild large herbivores affect ecosystems in numerous important ways, from soils to vegetation to smaller animals and promote ecosystem variability. An international team led by researchers from Aarhus University and the University of Göttingen carried out the study. They conclude that conservation and restoration efforts should include large herbivores given their profound, general importance for ecosystems, not least effects that are likely to make ecosystems more resilient to climate change.</p>
The researchers analyzed the DNA of 139 living species of large mammals, revealing a universal and dramatic decline in their populations
<p>For years, scientists have debated whether humans or the climate have caused the population of large mammals to decline dramatically over the past several thousand years. A new study from Aarhus University confirms that climate cannot be the explanation.</p>
