Blanketing a home garden in pesticides poses a clear risk to the humans and animals who dine on it. But when the garden is compared to a human immune system, another problem becomes apparent: Just like antibiotics, pesticides wipe out the “good bugs” with the bad. These helpful predators and parasitoids are called natural enemies and they help to naturally control pests like aphids and caterpillars. Certain plants attract natural enemies and/or deter pests all together and can be used in place of harmful chemicals.

It seems the only certainty amidst the Gulf of Mexico environmental disaster is that nothing is certain. From the amount of oil continually pouring from the seafloor to British Petroleum’s use of chemical dispersants, this crisis has been anything but straightforward. As evasive, and at times downright misleading, as BP has been, the environmental impacts of this disaster are far from allusive. Just take a look at the photos on the Public Broadcasting Service’s News Hour site to get a sense of urgency surrounding this crisis.

“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.

Nutritious, chemical-free and all-natural, insects are featured as the main protein several Latin American, Asian and African countries. For example, in the Santander region of Colombia, leaf-cutter ants (called “hormigas culonas”) are sometimes eaten roasted, salted and have a slightly acidic taste. Mopane worms—the caterpillar for the moth Gonimbrasia belina—are popular in Botswana and are served dried or rehydrated with sauces and other ingredients.

The Amazon rainforest—with its millions of creaking, chirping and buzzing insects, sticky frogs, vibrant birds, and unique fish—may owe its diversity primarily to flowers, said researchers from the University of Chicago. And, they say, just as flowering plants formed the building block of biodiversity in this region, their removal could result in a cascade of declining diversity.

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).

Representatives from around 90 countries approved the formation of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, Nature and Scientific American collaborated on a survey to analyze the public’s interest in science and the history of the tomato’s taxonomy in the United States is reviewed. Here are some stories in ecology from the second week in June.

This post contributed by ESA Science Policy Analyst Piper Corp. It isn’t surprising that climate legislation is stalling in Congress. In tough economic times, an emissions cap—like any other major investment—is a tough sell at best, requiring US households and industry to swallow added costs in the short-term for projected savings down the road. What’s more, the current symptoms of…

It goes without saying that tomorrow, June 11, 2010, literally kicks off the FIFA 2010 World Cup in South Africa. The media has been throwing around stories on projected winners, South Africa’s history in the making and even possible flu outbreaks from vuvuzelas. Fans around the world wait in anticipation; meanwhile in South Africa, staff from the Global Environment Facility (GEF), the United Nations Environment Program (UNEP) and the South African Department of Environmental Affairs (DEA) are trying to meet an ambitious “green” goal.

Male jumping spiders (Phidippus clarus) size one another up before engaging in a fight—whether the aggression is based on rights to mating or territory—and in many cases, the pre-fight displays are sufficient to deter physical contact. The males do not nest but instead wander between female nests looking for opportunities to mate. The females, on the other hand, are not nomads—they build nests from silk and leaves in which they wait while they draw closer to sexual maturity.

Scientists document cricket predation and reproduction, protestors cancel Oscar-winning anti-dolphin-hunting documentary in two Tokyo theaters, study describes the process of developing resistance to H1N1 treatments and researchers debate the possibility of achieving sustainable agriculture worldwide. Here is ecology in the news from the first week in June.
