Bet-hedging dry forest resilience to climate-change threats
New research shows that the most significant current threat to western dry forests is from insect outbreaks and droughts, not wildfires; and historically abundant small trees offer the greatest hope for forest survival and ...
Intensive agriculture may have exacerbated drought in ancient Maya city
NASA study shows 13-year record of drying Amazon caused vegetation declines
A 13-year decline in vegetation in the eastern and southeastern Amazon has been linked to a decade-long rainfall decline in the region, a new NASA-funded study finds.
Time-lapse photos and synched weather data unlock Antarctic secrets

'Eyespots' in butterflies shown to distract predatory attack
Research has demonstrated with some of the first experimental evidence that coloration or patterns can be used to "deflect" attacks from predators, protecting an animal's most vulnerable parts from the predators ...
Drug-infused nanoparticle is right for sore eyes
For the millions of sufferers of dry eye syndrome, their only recourse to easing the painful condition is to use drug-laced eye drops three times a day. Now, researchers from the University of Waterloo have ...
Pesticides are more toxic for soil organisms in dry soil and at enhanced temperatures
Soil organisms react more sensitive to marketable pesticides when exposed in dry soil and at enhanced temperatures. Both conditions may occur more often in the future due to climate change. Singularly and ...
