Not so sexy salmon

New research reveals that farmed salmon have smaller 'jaw hooks' or 'kype'- a secondary sexual trait, likened to the antlers of a stag, making them less attractive to females than their wild salmon cousins.

A new study has revealed that the language used by the global climate change watchdog, the Intergovernmental Panel on Climate Change (IPCC), is overly conservative – and therefore the threats are much greater than the Panel's ...

Climate-driven evolution in trees alters their ecosystems

A new study published in Global Change Biology and coauthored by researchers from UT, explores how climate, evolution, plants, and soils are linked. The research is the first to show how climate-driven evolution in tree populations ...
