By Gary Lovett, Senior Scientist and Forest Ecologist, Cary Institute of Ecosystem Studies, Millbrook, NY Tis the season when many Americans welcome trees into their homes. For millions of us, fresh-cut evergreens are at the heart of Christmas celebrations – a symbol of hope and joy. Sadly, the situation facing America’s trees is neither hopeful nor joyous. The Fraser fir, one…
By Cliff Duke, ESA’s director of Science Programs Americans are deeply divided about the proper uses of federal and private lands and the goods and services they supply us. Recent events, including the acquittal of the occupiers of the Malheur National Wildlife Refuge, protests of the proposed Dakota Access Pipeline, and the potential reopening of debates about the Keystone XL…
The U.S. Forest Service is revising the policies and guidelines governing the management of federal forests in the Pacific Northwest. Two decades of ecological research and monitoring data have accumulated since the adoption of the Northwest Forest Plan in 1994. To inform revisions, the Pacific Northwest (which includes Oregon and Washington) and Pacific Southwest (which includes California) Research Stations instigated…
A guest post by Teresa Mourad, ESA Director or Education and Diversity Programs with help from Arietta Fleming-Davies of QUBES and Radford University. Gaby Hamerlinck and Kristin Jenkins from QUBES and BioQuest, and Sam Donovan from QUBES and the University of Pittsburgh collaborated on this project. As computational power has expanded and cloud-based analytical tools become more accessible, the science…
By Elise Lipkowitz, Science Policy Analyst for the National Science Board Office It’s time again for the National Science Foundation (NSF, Foundation) to revise its Strategic Plan. As part of this process, the Foundation is looking for feedback from the science community on NSF’s current strategic plan (FY 2014-2018) and input on possible future strategic goals for the agency. If you…
Black-billed magpies and American crows, both members of the clever corvid family of birds, have adapted comfortably to life in urban and suburban communities. In Jackson Hole, Wyoming, the two species often nest nearby each other in backyards and parks. Nesting near their much larger crow cousins affords magpies a margin of extra safety from a common enemy—ravens, an even…
Ecological scientists are not known for elevated fashion sensibilities. Many take pride in a sartorial identity rooted in a field work chic of practical hats, cargo pants, and judicious applications of duct tape. Button-downs in botanical prints and ties in tiny repeating motifs of anatomically correct fish are favored formal attire when researchers gather for the Annual Meeting of the…
To restore the grasslands of the Great Plains, a Nebraska ecologist says, bring back high intensity fires Ecologist Dirac Twidwell wants to change the way we think about prescribed burns. The University of Nebraska professor says he can harness extreme fire to restore grasslands on the Great Plains—and, with the help of the Nebraska Intelligent MoBile Unmanned Systems (NIMBUS) Lab,…
One hundred and thirty years ago, the volcano Krakatoa erupted in what is now Indonesia, unleashing a cataclysm locally and years of cool temperatures and rain globally. On the far side of the world, a bumper crop of saguaro cacti were getting their start in life in Arizona’s Sonoran Desert. Many of the large exemplars of the famous cacti standing…
The aggressive, day-biting Asian tiger mosquito, Aedes albopictus, has spread with global trade from its native home in the tropics and subtropics of Southeast Asia. First observed in Houston, Texas, in 1987, it rapidly spread through the interstate system in the the United States. Its range is pushing northward into New York and Pennsylvania. Does Ae. albopictus crowd out other…
Invasive Aedes aegypti and Aedes albopictus are the principal vectors of dengue, chikungunya, and Zika viruses in the Americas. These species often find themselves in competition for mates and resources for their young. Cross-mating between the species creates infertile eggs and permanent sterilization of A. aegypti females. Lounibos and colleague Steven Juliano of Illinois State University described the causes and…
As an example of the costs of mosquito suppression, three imperiled native plants in the Lower Florida Keys suffer indirectly from the spraying of insecticides in housing developments flanking National Key Deer Refuge. Harris will present her work in a poster session on Conservation at the 2016 Annual Meeting of the Ecological Society of America in southern Florida this August. PS…
