A scientific team from the Doñana Biological Station – CSIC has looked at the variation in body size, appendage lengths, and other morphological traits across elevation and time in the Mountain Treeshrew, an endemic species from Borneo.
This new research suggests that this small mammal violates (entirely or partially) Bergmann’s and Allen’s rules. These are two key ecogeographical rules that describe size and shape variation among organisms, and predict that populations become...

what are the processes that have originated this high diversity in the tropics? Researchers of the Doñana Biological Station – CSIC wanted to address this question in their latest study, looking into the drivers that have originated this high diversity of shrews in the tropics, specifically in Sundaland, South-East Asia. The work has been carried out in collaboration with scientists from Geneva, Harvard and Smithsonian museums and Sabah Parks (Malaysia).
