Conservation Science

That people are fascinated by bats can be shown in the number of sold-out walk and talk tours scheduled by the Yolo Basin Foundation to watch the colony of Mexican free-tailed bats that take off from the Yolo Causeway on a hunt for insects every summer night. Fascination could turn to frustration, however, as bat populations decline in the face of an approaching threat. Fourteen hibernating bat species in Northern California are at risk from a fungus that causes white nose syndrome, which has been spreading westward since it originated in New York in 2006. ...

With wingspans of up to 3 metres, it should be hard to miss the largest bird in North America – but there aren’t a lot of them. The California condor is only just hanging on in its home state, but thanks to a gargantuan conservation effort, the tide may finally be turning.

From April 23rd through April 28th, 2015, I attended and presented at the 20th International Pectinid Workshop in Galway, Ireland with support from the Switzer Foundation Professional Development Grants program. From a professional development perspective, this workshop provided me with my first opportunity to give a presentation in front of a scientific audience beyond my thesis defense in graduate school.

A critically endangered French Polynesian ground-dove known locally as Tutururu has been given a new lease on life in its endemic home, the Tuamotu & Gambier Archipelagos. Only 150 of the birds remain in the world but safe habitats now available to them have more than doubled thanks to an ambitious conservation effort to eradicate introduced rats from the Tuamotu group.

Researchers at Woods Hole Oceanographic Institution (WHOI) have developed and successfully tested a method of collecting vital data on whales. According to a WHOI release, researchers used "whalecopters" to photograph and take non-invasive samples from humpback whales in Stellwagen Bank National Marine Sanctuary in July.

In 1994, southeast Alaska was home to about 300 Prince of Wales wolves, a subspecies of Alexander Archipelago wolves. By 2013, there were fewer than 250. Last year the population plummeted 60 percent to 89 wolves. New numbers confirm that the rare breed may have dropped to as few as 50. But the diminishing numbers won’t stop hunters from trapping and killing the wolves, according to the Center for Biological Diversity. The Alaska Department of Fish and Game is moving ahead with its 2015–2016 hunting and trapping season on Prince of Wales Island.

In one of the largest studies of its kind, a volunteer-fueled camera trapping effort showed that where coyotes have moved in, cats are nowhere to be found.

Many Californians appear to be taking up Gov. Jerry Brown's call for the removal of 50 million square feet of lawn energetically and enthusiastically. But all that energy may be misplaced: As homeowners and businesses seek out drought-tolerant, low-water plants at local nurseries and big-box garden departments, they may unwittingly be picking up invasive plants that wreak havoc on the state's ecology. ...

If you have ever witnessed the damage done by hurricanes that result in severe flooding to regional roads and wash outs at stream crossings, you may long for a crystal ball that would help prevent future destructive scenarios. However, the University of Massachusetts and their collaborators have a much better plan: assess and develop protocols that determine which roadway stream crossings are most vulnerable to climate change conditions well in advance of a disaster. Oh, and place culverts at the top of that list.
