Desperately Seeking Stable 50-Year-Old Landscapes with Patches and Long, Wide Corridors” in PLoS Biology.

I’m not sure if the authors purposefully came up with a title reminiscent of a personal ad, or if it’s just my overactive imagination. Either way, it makes me giggle. I mean, “long, wide corridors”? What a size queen.

For anyone wondering what the paper is actually about, the authors are looking for particular types of environments in order to investigate if corridors effectively conserve biodiversity. Human urbanization (roads, housing developments, Walmarts) serves as barriers that plants and animals have a hard time crossing. This fragments large populations into a lot of smaller ones that can’t interbreed as much. Small populations are more susceptible to events that reduce genetic diversity, like inbreeding and genetic drift. Decreasing genetic diversity is generally considered Bad, because…well, I’m lazy and Wikipedia does a good job at explaining:

“Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele. The population will continue for more generations because of the success of these individuals.”

Corridors are often used to attempt to make up for this fragmentation, and the authors want to see if the corridors are actually successful in promoting gene flow between populations. Thus their personal ad that made me giggle.
