UT scientists study how droughts affect local ecosystems at the Brackenridge Field Laboratory and the Stengl Lost Pines Biological Station.

New research provides the latest evidence that climate change is having an impact on food webs in high-latitude ecosystems.

In some species, female and male butterflies apparently perceive colors differently.

Poison frogs are able to withstand a toxin which they use to deter predators, but not without a cost.

An invasive grass causing havoc in Texas and contributing to wildfires packs a one-two wallop against native plants. Guinea grass uses a combination of crowding that blocks out light from growing seedlings and what amounts to a chemical warfare in soil that is toxic to native plants, according to a new study by researchers at The University of Texas at Austin.

Traditionally, it has been assumed that cultivating food leads to a loss of biodiversity and negative impacts on an ecosystem.

A new study has startling conclusions about how, on smaller islands in the Caribbean where human impact was greatest, extinctions have led to the loss of up to two-thirds of the supports for the ecosystem that native reptile species once provided there.

An international collaboration of researchers shows how the legacy of colonialism remains deeply entrenched within scientific practice across the Caribbean.

Instead of focusing entirely on biomass and one-size-fits-all solutions, researchers recommend finding which fish provide the most useful functions in each reef system and protecting them.

UT Austin scientists have demonstrated how to use a naturally occurring fungus to crush local populations of invasive tawny crazy ants.
