Dolphin 'Breathalyzer' Could Help Diagnose Animal and Ocean Health

624736.image1.jpg

Alcohol consumption isn't the only thing a breath analysis can reveal. Scientists have been studying its possible use for diagnosing a wide range of conditions in humans — and now in the beloved bottlenose dolphin. In a report in the ACS journal Analytical Chemistry, one team describes a new instrument that can analyze the metabolites in breath from dolphins, which have been dying in alarming numbers along the Atlantic coast this year.

Balancing Birds and Biofuels: Grasslands Support More Species Than Cornfields

In a new study, scientists examined whether corn and grassland fields could provide both biomass for bioenergy production and bountiful bird habitat. The research team found that grasslands supported more bird species than cornfields did, and new findings indicate grassland fields may represent an acceptable tradeoff between creating biomass for bioenergy and providing habitat for grassland birds.

A new paper from the Wildlife Conservation Society, Montana State University, Montana Department of Fish, Wildlife and Parks, and the U.S. Geological Survey looks at the feasibility of electrofishing to selectively remove invasive trout species from Montana streams as an alternative to using fish toxicants known as piscicides that effect all gill-breathing organisms.

Spiders: Survival of the Fittest Group

Researchers have uncovered the first-ever field-based evidence for a biological mechanism called 'group selection' contributing to local adaptation in natural populations. Evolutionary theorists have been debating the existence and power of group selection for decades. Now two scientists have observed it in the wild -- as they report in the journal Nature.

Genetic Secrets of the Monarch Butterfly Revealed

JCdR3.jpg

Sequencing the genomes of monarch butterflies from around the world, scientists have made surprising insights into the insect’s genetics. They identified a single gene that appears central to migration – a behavior generally regarded as complex – and another that controls pigmentation, as well as shed light on the evolutionary origins of the monarch.

Mountain Pine Beetles Get a Bad Rap for Wildfires, Study Says

New research led by the University of Wisconsin-Madison and the Washington State Department of Natural Resources provides some of the first rigorous field data to test whether fires that burn in areas impacted by mountain pine beetles are more ecologically severe than in those not attacked by the native bug. In a study published this week, UW-Madison zoology professor Monica Turner and her graduate student, Brian Harvey, show pine beetle outbreaks contributed little to the severity of six wildfires in 2011.
