Here are some highlights from the latest ESA Policy News by ESA’s Science Policy Analyst, Piper Corp.

Researchers have found that pheromones play a key role in reproduction and social status in the buff-tailed bumblebee colony. Specifically, sterile female workers seem to advertise their infertility with extra pheromones in an attempt to ward off harassment from competing bees.

In an article published earlier this week in Nature, researchers revealed the complete genome of the zebra finch and focused on the intricacies of their vocal communication. The zebra finch, the males of which are known to learn and repeat the same song generation after generation, show 800 active genes involved in vocalization. One group of researchers, however, found more…

Researchers have discovered three species of Loricifera living in an oxygen-starved basin at the bottom of the Mediterranean Sea. Loricifera are marine sediment-dwelling animals consisting of a head, mouth, digestive system and outer shell called a lorica.

Caterpillars create green islands in leaves, bats navigate long distances using a geomagnetic field and volcanic lake shows unexpected biodiversity. Here is what’s happening in ecology for the first week in April.

“Who will speak for the imperiled troglobites? Charismatic megafauna, they are not. Troglobites—not to be confused with troglodytes (cavemen) or trilobites (extinct arthropods)—are neither warm-blooded nor fuzzy. Most are invertebrates, including insects and crustaceans, but there are also troglobitic fish and amphibians—and all are as weird as they are rare.”

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.
