Washington [US], April 19 : According to a new study led by Alexander Dyer from the German Centre for Integrative Biodiversity Research (iDiv) and the Friedrich Schiller University Jena, Germany, published in the open-access journal PLOS Biology, an mal's travelling speed is limited by how effectively it sheds the excess heat generated by its muscles.An mal's capacity to travel is a crucial part of its survival and dictates where - and how far - it can migrate, find food and mates, and spread into new territories. This becomes even more challenging in a human-dominated world characterized by increasingly fragmented habitats and limited food and water resources under climate change.Dyer and his colleagues developed a model to look at the relationship between mal size and traveling speed, using data from 532 species. While larger mals should be able to travel faster due to their longer wings, legs or tails, the researchers found that medium-sized mals typically have the fastest sustained speeds. The researchers attribute this to the fact that larger mals require more time to dissipate the heat that their muscles produce while moving, and therefore, they must travel more slowly to avoid overheating. They conclude that any mal's traveling speed can be explained by jointly considering how efficiently it uses energy and sheds heat."The new study provides a way to understand mal movement capacities across species and can be used to estimate any mal's traveling speed based on its size," says Dyer. "For example, this approach can be applied to predict whether an mal might be able to move between habitats fragmented by human development, even when the details of its biology are unknown."Last author Dr. Myriam Hirt from iDiv and the University of Jena adds, "We anticipate that large mals are potentially more susceptible to the effects of habitat fragmentation in a warming climate than previously thought and therefore more prone to extinction. But this needs further investigation."Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
