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…
Read MoreBy Terence Houston, Science Policy Analyst In recent months, there have been multiple congressional attempts to interfere with the National Science Foundation’s support of the nation’s fundamental research particularly related to social and behavioral science research. Such attacks have happened periodically over the years, but recent actions have been particularly aggressive. Congressional Republicans have pushed legislative efforts to restrict federal…
Read MoreBy Nadine Lymn, ESA director of public affairs Many of us recognize that a large part of the solution to environmental problems lies in getting people to change their behavior. Unfortunately, altering the habits of the human animal can be especially challenging—we are intelligent but we can also be irrational and our age-old tendency to focus on immediate needs frequently…
Read MoreThis post contributed by Nadine Lymn, ESA Director of Public Affairs Just in time for Thanksgiving, comes the true-life tale of a man who raised a rafter of sixteen wild turkeys, gaining a newfound understanding and deep appreciation for them in the process. My Life as a Turkey aired on PBS last week and shows how naturalist and wildlife artist…
This post contributed by Lindsay Deel, a Ph.D. student in geography at West Virginia University and Intern with ESA’s journal Frontiers in Ecology and the Environment Infectious diseases won’t know what hit them. A massive new collaborative effort between funding sources in the United States (US) and United Kingdom (UK) takes aim at infectious diseases from ecological and social perspectives,…
Beer yeasts: Researchers at Lund University in Sweden tracked the history of two yeasts—Saccharomyces cerevisiae and Dekkera bruxellensis—used in alcohol fermentation to pinpoint their role in ethanol production. They found that, around 150 million years ago, competition with other microbes, and the overall increase in sugar-rich fruits, encouraged the yeasts to withstand high ethanol concentrations—an adaptation that would allow them…
Researcher David Hughes has expanded research on a parasitic fungus and its carpenter ant host. As explained in an excerpt from a previous EcoTone post: Scientists have found that the parasitic fungus Ophiocordyceps unilateralis has possibly been invading carpenter ants (Camponotus) for 48 million years. The parasite not only infects the ant, but it manipulates the ant’s behavior, driving it…
Scientists have found what appears to be the stress signals of a lake ecosystem that is on its way to collapse. Stephen Carpenter of the University of Wisconsin, Madison and colleagues carefully monitored the food web in a Wisconsin lake as they gradually introduced largemouth bass into the ecosystem. The researchers noticed a shift in the algae populations that were…
It may be difficult to picture just one locust singled out from a swarm. But believe it or not, desert locusts—insects infamous for their contribution to plagues and famine—are naturally solitary creatures. So what causes the group uprising that farmers are so familiar with? Research has shown that the internal workings of a solitary locust can affect the swarming behavior of the entire group.
