Interstate-90 is a priceless east-west conduit in Washington state. But for wildlife, it is a dike blocking the flow of migrating animals on both sides. Watch the video

Several studies have implicated lead poisoning in deaths of the endangered California condor. A study published this year found lead poisoning was the primary cause of death in juvenile and adult condors from 1992 to 2009. A 2010 study analyzed three to four months of lead levels using condor feathers and found much higher and more frequent exposures than blood draws suggested, said Myra Finkelstein, an environmental toxicologist at UC Santa Cruz, who conducted the study. Still other work tied the chemical composition of lead found in poisoned birds with that of ammunition.

Dr. Jeff Dlott is the father of one of the students (Chloe Dlott) where I am teaching this year. We connected early in the year when he realized we are both Switzer Fellows and have been in communication. Jeff did his Ph.D. in entomology, but now runs a sustainable agriculture company. I asked Jeff if he was willing to come and run two lab sessions with junior biology students.

This issue brief reports on the mechanics of and lessons learned from a conservation incentive program focused on the gopher tortoise. Its aim is to inform the successful design and implementation of other candidate programs emerging throughout the southern forests and greater United States. The Switzer Foundation is funding a pilot demonstration project to test the feasibility of the project concept. Read a summary and download the report

Sad tales of our failures in society to be adaptable, remarkable stories of the intricate ways in which natural organisms have survived and thrived for billions of years on an unpredictable planet, and hopeful examples of how all sorts of people, organizations, corporations and bureaucracies have learned to be adaptable.

The study, "Connecting Natural Landscapes Using a Landscape Permeability Model to Prioritize Conservation Activities in the United States," appears in the journal Conservation Letters. Authors include David Theobald of CSU, Kenyon Fields and Michael Soulé from Wildlands Network and Sarah Reed from the Wildlife Conservation Society. Read the full story
