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.
Twenty-five years ago on October 18, Nintendo launched its Nintendo Entertainment System in the United States and—depending on your point of view—began a video game revolution that has taken entertainment technology to previously unfathomable heights. Or it has captivated the attention and interest of millions of children and adults, in over two decades of software and console development, prompting Americans to stay indoors and avoid exercise. Perhaps you see it both ways.
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.
Imagine a small town where everything is uniform—a tiny community of individuals who eat the same meals and pair up with people with similar qualities and traits. The scenery is stripped down: one church, one pub and cookie-cutter houses. Now add in social interactions. Greetings occur but they have few variations; life is routine. And just a few miles over in a town with the same layout, similar individuals are interacting, eating and greeting, in all the same ways.
“Menopausal” aphids sacrifice themselves for the colony, Gulf oil spill myths debunked, the benefits of (and new considerations for) hiking, bee hives add to sustainable cuisine in San Francisco and the masters of disguise in the animal world—photos included. Here is the latest in ecological science from the third week in June.
Earlier this month at the Deepwater Horizon Oil Spill Scientific Symposium at Louisiana State University (LSU), scientists emphasized the importance and urgency of consulting with researchers during the remediation of the Gulf of Mexico disaster. The meeting pulled together more than 200 attendees, including officials from the National Oceanic and Atmospheric Administration (NOAA), the U.S. Geological Survey (USGS), the Environmental Protection Agency (EPA) and the National Science Foundation (NSF).
Many farmers throughout Latin America and around the world rely on pesticides to control pest invasions; in the case of Andean potato crops, this method is not only costly but has been shown to cause adverse health effects as well. Due to the risks involved in pesticide usage, and the ever-increasing demand for high-yield crops, new methods of controlling pest invasions are being explored by researchers regularly. And as counterintuitive as these new findings sound, ecological scientists have discovered that, in the case of Colombian potato farms in the Andes, the pests themselves could actually increase productivity.
Currently, upper respiratory tract disease (URTD) and habitat loss are contributors to a decline in gopher and desert tortoise populations. And since these reptiles are keystone species—that is, the habitats they create are home to more than 300 other species—their population decline significantly affects the ecosystem. According to a recent study in Ecology, sexually-mature male tortoises were at the greatest risk of carrying and spreading URTD due in large part to their social behavior.
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.
Early morning flyovers produce a 3D map of New York City’s environment, scientists analyze lizard competition in the Bahamas, Slate reviews the ecological cost of large scale illegal drug production and golden lion tamarins paint for an auction to fund National Zoo research. Here is the latest news in ecology for the first week in May.
