kkrisberg | January 22, 2016It’s been nearly two decades since the last publication of a nationwide survey on the distribution of blacklegged ticks — the primary transmitters of Lyme disease. That survey, released in 1998, reported the tick in 30 percent of U.S. counties. Today, a new study using similar surveillance methods has found the tick in more than 45 percent of counties.
“These kinds of changes tend to be gradual,” study co-author Rebecca Eisen, a research biologist in the Centers for Disease Control and Prevention’s Division of Vector-Borne Diseases, told me. “But when you see the cumulative change over 20…

This video documents the fact that "feral cat colonies" are a disaster for wild birds. Each year free-roaming and feral cats kill hundreds of million of birds in the United States. One controversial solution to deal with the feral cat problem is trap, neuter and release. However, evidence is growing that this method is not eliminating the cat colonies or the predation of birds and other wildlife. There are other problems…
