Researchers find 24 species believed new to science in Suriname rainforest

Scientists exploring the remote highlands of eastern Suriname discovered 24 species believed to be new to science, including a frog with florescent purple markings and other amphibians, fish and insects. Presented in a report made public today, the findings from a 2005 expedition ...

Caribbean frogs started with a single, ancient voyage on a raft from South America

...lete because many of the species are restricted to remote and isolated mountain tops or other inaccessible areas. Some species included in the study now are believed to be extinct because of habitat degradation and possibly other causes such as climate change. A recent global assessment of amphibians foun...

Small, self-controlled planes combine plant pathology and engineering

...t advantages over a sampling aircraft operated via remote control,” Schmale explained. “First, the autonomous UAVs maintain a very precise sampling path. We can establish a GPS waypoint in the center of an agricultural field, and the autonomous plane can circle around the waypoint at a set altitude, with ab...

He then analyzes those samples for pollen and charcoal and thus is able to conclude with a high degree of accuracy the extent of human settlement in that region. "What we do say is ...

Cambodian vulture nests offer hope for species

Working in the remote forests of Cambodia, conservationists from the Wildlife Conservation Society (WCS) have just discovered Southeast Asia's only known breeding colony of slender-billed vultures, one of the world's most threatened bird species. Found in heavily fores...
