Hybridization has led to some of the unique, naturally-occuring species present today, such as the Mallard duck-American Black duck hybrid. Usually this natural process takes generations to produce a new distinct species; however, it is possible for hybrids to emerge within one generation. For example, interspecies breeding could be expedited due to environmental stressors caused by climate change. Species that would not normally come...
Countless federal programs, including a disproportionately large amount of science and conservation programs, will be on the chopping block this year as Congress and the White House work to reign in federal spending in an effort to lower the deficit. The current debate focus is on discretionary spending which, according to Factcheck.org, accounts for 36 percent of total federal spending. The White House typically releases its budget...
Here are some highlights from the latest ESA Policy News by Science Policy Analyst Terence Houston.
Go to Google Images and search for “science.” What are the results? More than likely, the search will come up with beakers, protons, lab coats, double helixes, pulsars, microscopes and perhaps a smattering of trees and images of the globe. Photographs of researchers boot-high in streams collecting samples, for instance, or of a Cayman Island blue iguana in its natural habitat, would probably be few and far between. But images such as these—which show an aspect of the biological sciences, environmental processes or a subject of ecological research—rarely show up, even though they are of course also science.
Many animals migrate in the fall to exotic locales and warmer, more abundant southern climates. Among the more famous migrating winged species are monarch butterflies, but there are several species of birds that also migrate during the fall. Some of these birds, such as hawks, rest and “refuel” in the Gulf region of the United States as they traverse southward.
According to the Obama administration, for the first time since the creation of the Chesapeake Bay Program in 1983, the federal government is using its full force to prioritize restoration of the Chesapeake Bay. Speakers met on September 10 for a briefing in Washington, DC to discuss the government’s significantly expanded role in preserving the Bay and its watershed.
When it comes to habitat destruction, startling events like oil spills and deforestation are certain to grab the headlines. Yet as a new study in the journal Animal Conservation shows, sometimes habitat destruction can be so subtle that it passes under the eyes of all but the most astute scientists. David Pike and fellow researchers from the University of Sydney look at the case of reptiles in outcrops and find that people moving rocks less than 30 centimeters out of place can ruin the habitat for species like the endangered broad-headed snake that shelter in narrow crevices.
