Insects, not just wind, offer an ancient mechanism of orchid seed dispersal
On Yakushima Island, at the southern tip of Japan, an orchid employs a very unusual strategy to disperse its seeds. Crickets visit the orchid at night, eat its fruits, and defecate the seeds in the vicinity. The discovery, reported recently … Continue reading
Satellite monitoring may help preserve the Chesapeake Bay by improving farming practices
Restoring the Chesapeake Bay, the nation’s largest estuary, has for decades proven to be a fraught enterprise, beset by the interests of researchers, farmers, anglers, multiple governments, and a host of others. A new approach, recently reported in Remote … Continue reading

Deep-sea mussels still show biological rhythms tracking sunlight, tides
Like many land animals, marine organisms follow daily and seasonal clocks—in the water, those clocks are set by the cadence of the sun and the moon. But researchers hadn’t known if deep-sea creatures also exhibit biological rhythms, tucked away in … Continue reading

People who are likely to dismiss journalism as “fake news” tend to believe the world is predictable
The notion of “fake news” spread like wildfire in the United States after the 2016 election. Recent research in Psychological Science tried to determine what psychological factors drove this concept—generally defined as the suspicion that politically-biased news outlets produce deliberately … Continue reading

Seasonality shapes coevolution of parasites and hosts
Parasites and their hosts coevolve in an arms race influenced by environmental conditions. Seasonal change, for example, can shape the course of evolution, but precisely how has been something of a mystery. A recent study used lab experiments and mathematical … Continue reading

Country-level assessment hides big variations in soy’s carbon footprint
Analysts usually estimate a crop’s carbon footprint based on country-level factors. But that formulation isn’t adequate, according to a new analysis of soy exports from Brazil. Published in Global Environmental Change, the study tracked soy from specific production sites in … Continue reading
