GAINESVILLE, Fla. — A new University of Florida study shows cats are the dominant predator to mockingbird eggs and nestlings in urban areas, prompting conservationists to urge pet owners to keep felines indoors at night.

The findings challenge assumptions that urban areas are places of refuge for nesting mockingbirds, a species researchers say plays an important role in controlling insect pests and serving as environmental indicators for metropolitan areas. (more…)

GAINESVILLE, Fla. — When a movie character says, “It’s too quiet,” that’s usually a sign something bad may happen.

Now, University of Florida researchers have discovered that when variations of a certain protein in our cells are too quiet, it may add to the risk that someone will develop lung cancer. When scientists restored the protein to its normal, active self, its cancer-inhibiting properties reappeared. (more…)

GAINESVILLE, Fla. — A University of Florida study demonstrates extinction’s ripple effect through the animal kingdom, including how the demise of large mammals 20,000 years ago led to the disappearance of one species of cowbird.

The study shows the trickle-down effect the loss of large mammals has on other species, and researchers say it is a lesson from the past that should be remembered when making conservation, game and land-use decisions today. (more…)
