The light-sensing molecules in plants came from ancient algae
July 28, 2015 06:40 AM - Duke University

The light-sensing molecules that tell plants whether to germinate, when to flower and which direction to grow were inherited millions of years ago from ancient algae, finds a new study from Duke University.

The findings are some of the strongest evidence yet refuting the prevailing idea that the ancestors of early plants got the red light sensors that helped them move from water to land by engulfing light-sensing bacteria, the researchers say.

Going to the beach may require hand sanitizer in addition to sunscreen
July 15, 2015 01:07 PM - American Chemical Society

“No swimming” signs have already popped up this summer along coastlines where fecal bacteria have invaded otherwise inviting waters. Some vacationers ignore the signs while others resign themselves to tanning and playing on the beach. But should those avoiding the water be wary of the sand, too? New research in the ACS journal Environmental Science & Technology investigates reasons why the answer could be “yes.” Sewage-contaminated coastal waters can lead to stomach aches, diarrhea and rashes for those who accidentally swallow harmful microbes or come into contact with them. But over the past decade, scientists have been finding fecal bacteria in beach sand at levels 10 to 100 times higher than in nearby seawater.

Turtle Hotspots Identified Around the World Contain Diverse Species and Richness

Chelonian Conservation and Biology

Global biodiversity is becoming more threatened as the human population continues to grow and use the world’s resources. Turtles have the misfortune of being on the leading edge of biodiversity decline and serve as an indicator of ecosystem degradation.

Researchers have identified 16 turtle “hotspots” around the world. These regions host the many native species of tortoises and freshwater turtles. By focusing on such areas, conservationists can target preservation efforts where the greatest effects can be achieved.

Scientists from the Chelonian Research Foundation, Conservation International, and State University of New York at Stony Brook recently published an article in the journal Chelonian Conservation and Biology that names three types of hotspots—biodiversity hotspots, high-biodiversity wilderness areas, and turtle priority areas. Taxon richness and endemism values are offered for the 16 identified hotspots, which host 262 species, or 83 percent of all turtle species.
