Factors of surface thermal variation in high-mountain lakes of the Pyrenees.

Thermal variables are crucial drivers of biological processes in lakes and ponds. In the current context of climate change, determining which factors better constrain their variation within lake districts become of paramount importance for understanding species distribution and their conservation. I...
