Western Section Offers Students Hands-On Experience

On a hot August day at a ranch in Davenport, Calif. wildlife biology students shaded themselves with hats and sunglasses while practicing to chemically immobilize deer with dart guns.

The students — 14 in all — were there as part of a two-week annual field camp that gives aspiring wildlife professionals the opportunity to apply skills developed in the classroom out in the field. The camp, organized by The Wildlife Society’s Western Section representative and co-coordinator of the course Cynthia Perrine and held at the Swanton Pacific Ranch, was led by the course coordinator and associate professor at California Polytechnic State University John Perrine as well as 11 wildlife professionals from agency, academic, private and non‐profit sectors.

As part of the field camp, wildlife professionals demonstrated wildlife techniques in small mammal trapping and remote camera trapping, which students then tried their hand at. Students also learned to take measurement samples of chemically immobilized deer, tag them, reverse the immobilization and then release them. Participants had the opportunity to do mist-netting of bats for the first time as part of the camp, and although they weren’t allowed to handle the bats, they helped set up mist nests as well as identify bat species and record data on them.

When they weren’t out in the field, students and professionals engaged in discussions about topics such as challenges that women face in the profession. They also learned about the skills and experience needed to get TWS certification as a wildlife biologist and had the opportunity to talk informally to professionals in different sectors and ask them questions about their careers.

At the end of the course, the students received four units of credit and a grade for the course, which Perrine said is a quarter’s worth of instruction in only two weeks. They also took quizzes and tests throughout the course.

“I have gained so much in these past two weeks, more than I imagined,” said one student in an anonymous course evaluation. “These skills I have learned I hope to take with me to future jobs and internships.”

What do Yosemite Bears and Aleutian Rats Have in Common?

Figuring out exactly what animals eat is one of the best ways to understand how ecosystems work and, if necessary, conserve them. But the problem is that animals, like humans, are complicated — their tastes change depending on a number of variables such as seasonal changes and whether they are male or female.

To understand some of the ways animals respond to changes in their environment, researchers created a new model that makes use of stable isotope analysis to determine the proportions of different things in the diets of black bears (Ursus americanus) in California’s Yosemite National Park and Norway rats (Rattus norvegicus) in the Aleutian Islands, Alaska.

“The reason we used data from both these animals is because they are both omnivores,” said Carolyn Kurle, assistant professor of biology at the University of California, San Diego and coauthor of a new study in Methods in Ecology and Evolution. “They both eat huge varieties of things.”

Kurle focused her work on the rats, which are an invasive species introduced into some of the islands in decades past. The rats laid waste to seabird populations on islands after arriving — so much so that the islands with rats rarely have birds. But after the damage to bird populations was done, Kurle wanted to know how the rodents managed to persist without that food source.

She took tissue samples from the rats and found through stable isotope analysis that they subsisted predominantly on plant matter from the bushes and shrubs on the stark islands. But during the late summer and fall, the rats gorged themselves on amphipods that turned up as storms in that season washed kelp onto the shore. “They rely on this pulse of marine protein,” Kurle said.

Meanwhile in Yosemite, postdoctoral fellow and lead author of the study Jack Hopkins analyzed the stable isotopes of diets of black bears and found that the bears subsisted mostly on pine nuts, acorns, and plants without much reliance on insects, as was previously thought.

“We need to know what they’re eating in Yosemite,” Kurle said of the black bears. Park managers can then determine how much human garbage and food the bears are eating, and can give some indication of whether efforts to limit bears’ access to this food source is working.

They also found diets differed between male and female bears.

“Female bears foraged for high-fat acorns and pine nuts more heavily than males, suggesting that females likely need these seeds for reproduction,” Hopkins said in a press release. “This could be a real problem for Sierra [Nevada] black bears in the future if blister rust continues to kill sugar pines and sudden oak death moves in from the coast.”

Kurle said that this could also mean that females eat different foods than males as a way to avoid them while their cubs are around, since male bears are known to kill infant bears.

She said that both of these kinds of studies give us a better understanding of how ecosystems work, and how managers can help with conservation.

“They can help us understand what animals with conservation interest are foraging on. What they’re eating and why we should care.”

Boreal Forests Could Hit Climate Change “Tipping Point”

Boreal forests could be hard hit from climate change by the end of the century without better international policy and management, according to researchers.

“It is urgent that we place more focus on climate mitigation and adaptation with respect to these forests, and also take a more integrated and balanced view of forests around the world,” said Anatoly Shvidenko in a release. Shvidenko is an Ecosystems Services and Management Program researcher with the International Institute for Applied Systems Analysis and coauthor of a new study published in Science.

The researchers reviewed recent field research to find that boreal forests of Canada, Russia, Alaska and Scandinavia represent around 30 percent of the total forest of the planet. Aside from playing home to many northern species of flora and fauna, they also regulate the planet’s climate themselves by sequestering carbon dioxide from the air.

But studies show that the climate is warming up in these northern areas 10 times faster than forests can migrate northwards. Meanwhile, warmer conditions are causing the outbreak of more wildfires and the spread of deadly insects.

“These forests evolved under cold conditions, and we do not know enough about the impacts of warming on their resilience and buffering capacity,” Shvidenko said. “Boreal forests have the potential to hit a tipping point this century.”

One of World’s Most Invasive Bugs Stopped at Toronto Airport

U.S. border agents discovered one of the world’s most invasive insects hiding in a bag of dried beans in a checked bag at Toronto’s Pearson International Airport. The khapra beetle, native to India, is particularly adept at attacking dried stored goods like wheat, barley, rice, and even chocolate. The bug was first detected in the U.S. in California in 1953, when it cost $15 million to eradicate. The bag was en route to Atlanta when it was intercepted.

Submit Your Research to the Western Wildlife Journal

Western Wildlife is an open-access, peer-reviewed journal that publishes original research, reviews, perspectives, and correspondence on the ecology, natural history, management, and conservation biology of vertebrates. All vertebrate taxa will be considered. While the primary geographic coverage is western North America, the journal accepts relevant wildlife manuscripts outside this area as well.

Western Wildlife is a continuation of the Transactions of the Western Section of The Wildlife Society and the journal will continue to cover traditional wildlife species and management topics related to these species, but the coverage is broadened to reflect the need for information on species and topics that are affected by human growth and development. The journal also will publish basic biology of species if the data are robust and soundly collected. Surveys and population monitoring data are within the scope of the journal, especially if the groups studied are of conservation concern. The journal welcomes student publications that fit within the scope and standards of the journal.

Western Wildlife is committed to its authors and finalized, accepted manuscripts are uploaded to the website as soon as final formatting is completed. In addition, the title, author(s), abstract and a link to the full article are emailed to the Western Section membership once the manuscript has been uploaded to the website.

British Columbia Opens Comment Period for National Park

The British Columbia Government is revisiting the idea of a Canadian national park in B.C.’s South Okanagan region near the Washington border after previous park discussions broke down in 2011. The newly released park proposal represents an area along the edge of Canada’s only desert that is home to 30% of B.C.’s red-listed species and 10% of Canada’s threatened species. The B.C. Government will be accepting public feedback on the proposal until October 12.

To learn more about the proposed park and to submit feedback, visit B.C. Parks.

Gravel Nest Camouflage Helps Snowy Plovers Reproduce

The type of nest snowy plovers (Charadrius nivosus) use determines much about their reproductive success, according to a recent study.

In a paper published in The Condor: Ornithological Advances, researchers from Humboldt State University reported that when the threatened plovers nested on gravel bars as opposed to sandy beaches, they raised more successful offspring. The team measured the birds’ “lifetime reproductive success,” or the total number of successful offspring an individual produces over the course of its lifetime.

The study looked at plover reproductive success, or LRS according to Dana Herman, a graduate student at Humboldt State University and the lead author. Herman said LRS studies are challenging because they require long-term monitoring of marked populations. However, the breeding population in Humboldt County has been studied and color-marked since 2001.

Herman and her adviser Mark Colwell tracked reproductive success of nearly 200 Snowy Plovers in Humboldt County, Calif. They studied possible factors influencing reproduction including human activity, predator presence, exclosures (cages placed around the nests to keep predators out), and what the birds nested in. The researchers found that the factors that stood out most was whether the birds nested on sandy beaches or gravel bars.

Gravel nests tended to provide better camouflage for the eggs and chicks, the researchers found. This caused higher lifetime reproductive success for the birds that nested in gravel nesting sites. While gravel-nesting birds laid fewer eggs overall compared to sand-nesting birds, the birds that had the benefit of gravel acting as camouflage to predators were able to raise more offspring successfully.

Herman and Colwell suggest that to help with snowy plover conservation, managers can add crushed shells or driftwood to sandy nesting sites to get the benefit of the camouflage that gravel nest sites supply. They also found that nest exclosures did not have an effect on reproductive success and might actually cause further problems for adults entering and exiting the nests.
