Ecology, Robotics and Love on the Lek

Gail Patricelli, a professor within the Department of Evolution and Ecology in the College of Biological Sciences at UC Davis and self-titled “pornothologist,” has developed her own FemBots to gain a better understanding of the sexual selection behaviors of sage-grouse.

Cow Gene Study Shows Why Most Clones Fail

It has been 20 years since Dolly the sheep was successfully cloned in Scotland, but cloning mammals remains a challenge. A new study by researchers from the U.S. and France of gene expression in developing clones now shows why most cloned embryos likely fail.

Why Insect Pests Love Monocultures, and How Plant Diversity Could Change That

Left to its own defenses, a farm field growing a variety of plants tends to attract fewer insect pests than a field growing just one type of crop. While scientists and farmers have noted that difference for years, the reasons behind it have been poorly understood. A study led by the University of California, Davis, and published Oct. 12 in the journal Nature explains that much of the discrepancy may have to do with the nutritional needs of insects.

Bringing Back White Abalone, One Spa Treatment at a Time

To encourage spawning in captivity, researchers put the marine snails in a mild hydrogen peroxide solution. This hydrogen peroxide spa treatment tricks the abalone into thinking others are spawning too. The chemical reaction, which creates free radicals, may be the same or at least similar to the chemical reaction that occurs when another abalone is spawning.

Nine Ways UC Davis is Rescuing Oceans

World Oceans Day is June 8. It’s a day across the world to celebrate our large expanses of sea and to collaborate for a better future. And this is just what UC Davis scientists are doing. Our researchers are discovering how climate change and human garbage hurt our oceans and their flora and fauna.
