Iron-rich meltwater from Greenland’s glaciers are helping fuel a summer bloom of phytoplankton.

Right now, a prairie dog in Colorado is busy increasing soil carbon retention, increasing water infiltration, and clipping vegetation that will help maintain local grasslands and provide nutritious forage for large herbivores like cattle and bison. And, somewhere in Mexico, a pollinating bat is ensuring agave plants make good tequila.

University of Adelaide researchers have for the first time demonstrated that the ocean acidification expected in the future will reduce fish diversity significantly, with small ‘weedy’ species dominating marine environments. 

Hot new imagery from temperature-sensing cameras suggests that bats who warm up from hibernation together throughout the winter may be better at surviving white nose syndrome, a disease caused by a cold-loving fungus ravaging insect-eating bat populations in the United States and Canada. The study by researchers with Massey University in New Zealand and the USGS was published in Methods in Ecology and Evolution.  

There are so many Antarctic krill in the Southern Ocean that the combined mass of these tiny aquatic organisms is more than that of the world’s 7.5 billion human inhabitants.

Scientists have long known about this important zooplankton species, but they haven’t been certain why particular regions or “hotspots” in the Southern Ocean are so productive.

Four hundred million lines of text: that’s how much data is in a single gene-sequencing file when Scott Pavey’s team receives it. If you wanted to scan it manually, and generously assume it would take one second per line to look at, it would take you 12 and a half years of reading around the clock to get through it all.

High-resolution earth imagery has provided ecologists and conservationists with a dynamic new tool that is enabling everything from more accurate counting of wildlife populations to rapid detection of deforestation, illegal mining, and other changes in the landscape.

Scientists recently reconstructed the skin of endangered green turtles, marking the first time that skin of a non-mammal was successfully engineered in a laboratory, according to a recently published U.S. Geological Survey study. In turn, the scientists were able to grow a tumor-associated virus to better understand certain tumor diseases.

Bumble bees create foraging routes by using their experience to select nectar-rich, high-rewarding flowers. A study by Shohei Tsujimoto and Hiroshi Ishii of the University of Toyama in Japan now suggests that bees actually forage more efficiently when flower sizes are large rather than small. This indicates that for these insect pollinators foraging quickly is more efficient than foraging accurately. The research is published in Springer’s journal Behavioral Ecology and Sociobiology and uses a laboratory-based experiment to investigate how aspects of associative learning influence how bumble bees find food among different-sized flowers. 

Male birds often use brightly coloured plumage to be attractive to females. However, such eye-catching trimmings may also attract unwanted attention from predators. Now, a new study led by Monash University has found that showy males indeed perceive themselves to be at a greater risk of predation.
