• Termite mounds could help prevent spread of deserts

    Termites might not top the list of humanity's favorite insects, but new research suggests that their large dirt mounds are crucial to stopping deserts from spreading into semi-arid ecosystems. The results indicate that termite mounds could make these areas more resilient to climate change. The findings could also inspire a change in how scientists determine the possible effects of climate change on ecosystems.

  • Pigeons are smarter than you think!

    The more scientists study pigeons, the more they learn how their brains--no bigger than the tip of an index finger--operate in ways not so different from our own.

    In a new study from the University of Iowa, researchers found that pigeons can categorize and name both natural and manmade objects--and not just a few objects. These birds categorized 128 photographs into 16 categories, and they did so simultaneously.

  • Plants Can be 'Reprogrammed' for Drought Tolerance

    Crops and other plants are constantly faced with adverse environmental conditions, such as rising temperatures (2014 was the warmest year on record) and lessening fresh water supplies, which lower yield and cost farmers billions of dollars annually. Drought is a major environmental stress factor affecting plant growth and development.  When plants encounter drought, they naturally produce abscisic acid (ABA), a stress hormone that inhibits plant growth and reduces water consumption.  Specifically, the hormone turns on a receptor (special protein) in plants when it binds to the receptor like a hand fitting into a glove, resulting in beneficial changes – such as the closing of guard cells on leaves, called stomata, to reduce water loss – that help the plants survive.

  • Seabirds suffer from pollutant exposure

    Seabirds, aerial ocean predators, are known to amass harmful contaminants over their lifespan. Scientists believe this exposure to pollutants, such as blood mercury (Hg), cadmium (Cd), and persistent organic pollutants (POPs), negatively impacts survival rates as well as reproduction, therefore contributing to large-scale population declines. Although previously these assumptions were largely theoretical, recent research in the Proceedings of the Royal Society B involving blood samples from wandering albatrosses points to new conclusions.

  • Scientists discover organism that hasn't evolved in more than 2 billion years

    An international team of scientists has discovered the greatest absence of evolution ever reported — a type of deep-sea microorganism that appears not to have evolved over more than 2 billion years. But the researchers say that the organisms’ lackof evolution actually supports Charles Darwin’s theory of evolution. The findings are published online today by the Proceedings of the National Academy of Sciences.

  • Ocean acidification changes balance of biofouling communities

    A new study of marine organisms that make up the ‘biofouling community’ — tiny creatures that attach themselves to ships’ hulls and rocks in the ocean around the world — shows how they adapt to changing ocean acidification. Reporting in the journal Global Change Biology, the authors examine how these communities may respond to future change.

  • How did the Zebra get its stripes?

    One of nature’s fascinating questions is how zebras got their stripes.

    A team of life scientists led by UCLA’s Brenda Larison has found at least part of the answer: The amount and intensity of striping can be best predicted by the temperature of the environment in which zebras live.

    In the January cover story of the Royal Society’s online journal, Open Science, the researchers make the case that the association between striping and temperature likely points to multiple benefits — including controlling zebras’ body temperature and protecting them from diseases carried by biting flies.

  • Research shows loss of pollinators increases risk of malnutrition and disease

    A new study shows that more than half the people in some developing countries could become newly at risk for malnutrition if crop-pollinating animals — like bees — continue to decline. Despite popular reports that pollinators are crucial for human nutritional health, no scientific studies have actually tested this claim — until now. The new research by scientists at the University of Vermont and Harvard University has, for the first time, connected what people actually eat in four developing countries to the pollination requirements of the crops that provide their food and nutrients.

  • Ebola impacting Chimps and Gorillas even more than humans

    While the whole world is aware of the many human fatalities from the Ebola epidemic in Western Africa, you may not realize that the disease has claimed hundreds of thousands of other victims in the area. Unfortunately, Ebola is simultaneously working its way through gorilla and chimpanzee populations with no sign of stopping. In the past 25 years, Ebola has wiped out 33% of all apes, reports the Daily Beast.

    Apes are already up against a number of obstacles that threaten their lives like poaching and habitat destruction. The last thing they need is to have a highly fatal disease reduce their numbers further. It’s even more devastating when you reflect on the fact that many of these primate species that are ravaged by Ebola were already officially listed as endangered.

  • Missouri River Sturgeon need more oxygen to reproduce. Dead zones, dams implicated.

    Pallid sturgeon come from a genetic line that has lived on this planet for tens of millions of years; yet it has been decades since anyone has documented any of the enormous fish successfully producing young that survive to adulthood in the upper Missouri River basin.

    Now, fisheries scientists with the U.S. Geological Survey, Montana State University and the U.S. Fish and Wildlife Service have shown why, detailing for the first time the biological mechanism that has caused the long decline of pallid sturgeon in the Missouri River and led to its being placed on the endangered species list 25 years ago.

    In a paper published this week in the journal Fisheries, the scientists show that oxygen-depleted dead zones between dams in the upper Missouri River are directly linked with the failure of endangered pallid sturgeon hatched embryos to survive to adulthood.
