Invasive Grass in Texas Uses Chemical Warfare to Crowd Out Native Species
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.
Urban Gardens Are Good for Ecosystems and Humans
Traditionally, it has been assumed that cultivating food leads to a loss of biodiversity and negative impacts on an ecosystem.
Loss of Reptiles Poses Threat for Small Islands Where Humans May Have Caused Extinctions
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.

Invading Hordes of Crazy Ants May Have Finally Met Their Kryptonite
UT Austin scientists have demonstrated how to use a naturally occurring fungus to crush local populations of invasive tawny crazy ants.
Some Trees May Play an Outsized Role in the Fight on Global Warming
A new study shows that nitrogen-fixing trees could help forests remove more heat-trapping COS from the atmosphere than previously thought.
Switchgrass Genes Offer Advantages as Climate Change Tool
This native grass can capture atmospheric carbon in its substantial root system.
Like Their Domestic Cousins, Native Bees are Hurt by Pesticides
Numerous studies have found negative impacts of agrochemicals, such as neonicotinoids, on both honey bees and native bees, and researchers like Felicity Muth and her lab at UT Austin are contributing to this field.
