It’s been roughly 80 years since the red imported fire ant (Solenopsis invicta) arrived from South America to Mobile, Alabama in soil used as ballast to weigh down boats. Needless to say, fire ants have adapted well in southern states like Texas, Louisiana and Florida, disrupting native wildlife and plants and causing problems for people ranging from shorting out street lights to stinging limbs.

But in the late 1990s and early 2000s, scientists brought over several strains of parasitoid flies from Argentina in an attempt to naturally eradicate the fire ants. A scientist recently found that one particular fly strain may be able to completely wipe out fire ants in northern Florida.

Just off the coast of Peru, the Humboldt Current produces one of the most productive marine ecosystems on the planet. Humans and animals alike have based their livelihood on the abundance of marine life that results from the deep, nutrient-rich waters of this coastal upwelling. Seabirds, which gather in massive groups off the coast to prey on schools of fish, have been completely sustained, until recently: Anchovy decline from overfishing and El Nino’s warmer waters have led to a major drop in seabird populations. One resilient bird, however, has held steady due to its solitary hunting style.

Architects, ecologists and urban planners design projects to tackle upcoming waterfront property issues in New York City due to rising sea levels from climate change, zebra finches play electric guitar as they go about their routines in a London exhibit and bacteria colonies produce intricate Petri dish art. Here is what’s happening in ecology for the last week in March.

Here are some highlights from the latest Policy News.  See the full edition here.   AIR POLLUTION: CARPER PLANS FOR APRIL MARK-UP OF 3-POLLUTANT BILL–Senator Tom Carper (D-DE) said this week that he expects a mid-April markup of legislation to curb power plant pollution in the full Environment and Public Works (EPW) Committee. Carper, who chairs the Clean Air Subcommittee,…

One hundred million years ago, Earth experienced its first great peak in biodiversity. Flowers emerged and with them pollinators, dinosaurs towered over newly evolved mammals and marsupials, the steaming jungles were teeming with newly arrived ants and termites, and the oceans were filled with gigantic, air-breathing reptiles. This was life during the Cretaceous period, Earth between two great extinctions.

Scientists are still uncovering the potential uses for nanotechnology. Just this month, researchers have reported on nanotechnology’s potential to eradicate cancer cells and blood diseases, desalinate seawater on the go and convert environmental energy waste to hydrogen fuel. With new research arising daily, it seems nanotechnology could have many applications in medicine and alternative energy.

Video describing the challenges of male pregnancy, photo gallery of the oldest trees in the world, podcast outlining Earth’s environmental tipping points and an article on adapting to the anthropocene. Here is ecological news from the third week in March.

Just last week, two Hawaiian bird species from the island of Kaua’i and their respective habitats were put on the endangered species list along with a Hawaiian fly and 45 types of Hawaiian plants. However, while the action signifies movement from the Obama Administration toward protecting at-risk species and their habitats, the listing does not come a second too soon: Recent research shows U.S. birds, especially in Hawaii, are in great peril.

In the tragic battle against devil facial tumor disease (DFTD), scientists may have found the first “glimmer of hope” near Cradle Mountain in northwestern Tasmania. At least that is what Katherine Belov of the University of Sydney and colleagues are saying about this unique colony that has resisted the disease.

When we consider all the conservation challenges facing our world and society, we know that communicating effectively to the community is not only helpful but necessary. However, many inspiring projects in various conservation areas have failed to succeed—not because the scientific background was not there or because the financial resources were unavailable—but because the community’s support was not entirely there. One of the elements to a successful conservation project is a strong connection to the community, especially during the early stages of project planning.

Aquanaut describes plans to colonize the sea for education and conservation, a pitcher plant previously thought to be carnivorous has been wildly reclassified and the first condor egg in 100 years discovered in California. Here are news stories and studies on ecological science from the second week in March.
