Trashy Life: Crayfish Turn Rubbish into a Home

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from the USDA’s rich science and research portfolio.

To raccoons, snakes and opossums, crayfish look pretty tasty, and large crayfish will even cannibalize their smaller kin. Crayfish, which live in rivers and streams, need instream cover to hide from all their predators. They also use cover to find food, to shelter while incubating eggs, and to keep themselves from being washed away in floods.

Susan Adams, a fisheries research scientist for the Forest Service’s Southern Research Station, examined different types of cover in the Yazoo River basin of Mississippi to see whether crayfish used large pieces of household trash for shelter when natural cover was limited. Her findings recently appeared in the journal Environmental Management.

Leaf Litter Keeps Ground-Roosting Bats Warm

When winter weather arrives, most bats hibernate in caves, but a few species migrate to warmer areas. Warmer being relative, the migrating bats may still end up in places that are too cold for comfort, and sometimes hibernate under leaf litter for short periods of time.

Roger Perry, a wildlife biologist at the U.S. Forest Service’s Southern Research Station, studied these temporary hibernation sites to find out how much protection they offered bats, and how much energy bats expend to stay alive.

The leaf litter study took place in and around the Alum Creek Experimental Forest of the Ouachita National Forest in Arkansas, and focuses on eastern red bats, a migratory species that remains active through most of the winter. When winter temperatures are not too cold the bats roost in trees, but when temperatures plunge, the bats temporarily hibernate underneath leaf litter.

What Will Become of Your Forest Land When You are Gone?

Family forest owners may use consulting foresters or state extension foresters for advice on the technical details of land management, but many owners shy away from thinking about how best to pass their forest on to the next generation.

Poor estate planning – or no planning at all – can result in a tax bill that requires selling timber or forest land, which in turn can lead to subdivision and development.

Estate Planning for Forest Landowners is a free publication developed by the U.S. Forest Service that provides a comprehensive guide to estate planning specifically designed for forest landowners.

Restoration Efforts May Mean More 'Chestnuts Roasting....'

“Chestnuts roasting on an open fire,” is a line from a song that conjures up fond holiday memories for some Americans. For others, the joy of roasting chestnuts has yet to be experienced. But the lack of American chestnuts could change in the coming years, thanks to some very dedicated people.

The U.S. Forest Service and its partners may be one step closer to restoring the American chestnut tree to parts of the mountains and forests of the southern United States. Since 2009, they planted close to 1,000 potentially-blight resistant American chestnut trees on national forests in North Carolina, Tennessee and Virginia.

Woodpecker Condos Bring Endangered Bird Back from the Brink in South Carolina

Many stories emerging from the Francis Marion National Forest share a common genesis in Hurricane Hugo, the massive storm estimated to have knocked down nearly a billion board feet of timber on the coastal South Carolina forest in 1989.

But in a comeback success story, there was no knock-out for the red-cockaded woodpecker.

Before Hugo, the Francis Marion had the densest, second-largest, and only known, naturally increasing population of red-cockaded woodpeckers in the country. Prior to 1989, an estimated 475 breeding pairs lived on the forest.

Finding ‘Gold’ in Bug Bellies

Almost three years ago, two biology professors at Delta State University in Mississippi brainstormed how to give science undergraduates research experience in microbiology and entomology.

They hit upon the idea of searching for “science gold” in the bellies of bugs.

Professors Tanya McKinney and Ellen Green received $40,000 through a grant for under-represented colleges from the U.S. Forest Service to help with the project. As part of their research experience, students in the program search the guts of beetle larvae to discover new cellulases, enzymes that break down cellulose, an organic compound that helps make plant cell walls rigid.

The Slippery Slope of Ramps

To many of locals in western North Carolina, they’re called wild leeks.  Some call them ransoms and still others call them wood garlic because of their pungent smell. Nevertheless, ecologists simply call them ramps. This native plant has been useful to humans since inhabiting the eastern regions of the U.S. and Canada.  Still today, locals harvest ramps for food, medicinal preparations, and to sell at markets and spring festivals.

Finding and Controlling Invasive-Plants? There’s an App for That

The Forest Service has added an iPhone/iPad application called Invasive Plants in Southern Forests: Identification and Management to its strategy of reducing nonnative invasive plants in the South.

The free app will allow more people to get involved in eradicating foreign plants, which, along with nonnative animals and pathogens, harm water supplies.  They also harm native plants, wildlife, livestock and property in both rural and urban areas at a cost of about $138 billion annually.

USDA Forest Service Helping to take Sting out of Bugs

How do you turn biting, stinging, pantry raiding, picnic ruining pests into pollinating, irrigating, aerating, fertilizing, ecosystem balancing helpers? … By educating as many people as possible about the role of bugs in the environment.

One of the responsibilities of the U.S. Forest Service is to inform the public about the value of insects in helping to sustain the health, diversity and productivity of the nation’s forests and grasslands.

With many people either afraid of or grossed out by bugs, changing their negative image is a challenge. However, a partnership between the Forest Service Southern Research Station and Kent House, in Alexandria, La., is demonstrating a growing public interest in insects.
