Study finds that human occupation of an area may not contribute to population decline of an endangered species

COLUMBIA, Mo. – Conservation of a protected or endangered species requires frequent monitoring and the dynamic techniques biologists utilize to ensure the survival of threatened animals. Often, scientists study biodiversity at all levels—from genes to entire ecosystems. Currently, researchers at the University of Missouri are employing genotyping to study movement patterns of African forest elephants in protected and unprotected regions of Gabon to better understand how human occupation of these areas might affect elephants on the African continent. Genotyping is helping conservation biologists determine the best course of action to ensure biodiversity and the preservation of various species in the U.S. and abroad. (more…)

Outdoor recreationists should take precautions to avoid problems with bears in southern Missouri

COLUMBIA, Mo. — For nearly a century, the only bears known to reside in Missouri were on the state flag or in captivity. Unregulated hunting and habitat loss had wiped out most black bears in Missouri, Arkansas and Oklahoma by the 1920s. Now, thanks to a reintroduction program in Arkansas during the 50s and 60s, hundreds of bears amble through the forests of southern Missouri, according to a joint study by University of Missouri, Mississippi State University, and Missouri Department of Conservation biologists, who warn that although the bear population is still small, outdoor recreationists and homeowners should take precautions in the Ozark forest to avoid attracting bears.

“Black bears normally do not attack humans, but they will ransack picnic baskets, tear through garbage bags or even enter buildings looking for food,” said Lori Eggert, associate professor of biological sciences in MU’s College of Arts and Science. “Although some Missourians may be concerned, the return of black bears to Missouri is actually a good sign. It means parts of the state’s forests are returning to a healthy biological balance after nearly two centuries of intensive logging and exploitation.” (more…)

Southwest Regional Warming Likely Cause of Pinyon Pine Cone Decline, Says CU Study

Creeping climate change in the Southwest appears to be having a negative effect on pinyon pine reproduction, a finding with implications for wildlife species sharing the same woodland ecosystems, says a University of Colorado Boulder-led study.

The new study showed that pinyon pine seed cone production declined by an average of about 40 percent at nine study sites in New Mexico and northwestern Oklahoma over the past four decades, said CU-Boulder doctoral student Miranda Redmond, who led the study. The biggest declines in pinyon pine seed cone reproduction were at the higher elevation research sites experiencing more dramatic warming relative to lower elevations, said Redmond of CU’s ecology and evolutionary biology department.

To preserve forest health, the best management decision may be to do nothing

In newscasts after intense wind and ice storms, damaged trees stand out: snapped limbs, uprooted trunks, entire forests blown nearly flat.

In a storm’s wake, landowners, municipalities and state agencies are faced with important financial and environmental decisions.

A study by Harvard University researchers, supported by the National Science Foundation (NSF) and published in the journal Ecology, yields a surprising result: when it comes to the health of forests, native plants and wildlife, the best management decision may be to do nothing. (more…)
