The world needs death and decomposition

What if roadkill piled beside the road and never decomposed? What if massive fish kills washed up on beaches and remained for eternity?

First off, it would be disgusting. Second, the Earth might run out of the key elements these organisms contain.

Thanks to a new study by Michigan State University, scientists now have a better way...

Carrier status matters in foot-and-mouth disease

Foot-and-mouth disease virus (FMDV) is believed to be one of the most contagious pathogens of animals in its acute form; however, there is still controversy over whether it is transmissible from asymptomatic, long-term carriers. Despite the lack of evidence for transmission by direct contact with FMDV carrier cattle, there is demonstrable contagion associated with these...

Turtle species in serious decline: Broad ecological impacts

Approximately 61 percent of the world's 356 turtle species are threatened or already extinct, and the decline could have ecological consequences.

These findings are according to a paper in the journal BioScience synthesizing the global status of turtles and their ecological roles by scientists from the U.S. Geological Survey, Tennessee Aquarium Conservation Institute, University of California,...

Beetle adapts chemical mimicry to parasitize different bee species

A beetle that tricks bees into carrying it into their nests where it can live off their pollen, nectar and eggs adapts its deceptions to local hosts, according to research by Leslie Saul-Gershenz, a graduate student in entomology at UC Davis.

Aggregations of the larvae of Meloe franciscanus beetles lure male digger bees (genus Habropoda) with...

Health of the Greater Yellowstone ecosystem

A Montana State University study of Yellowstone National Park and the surrounding area shows that increased population and density, as well as a changing climate, are affecting the overall ecological health of the region.

"The study quantified trends in the condition of 35 ecological 'vital signs' dealing with snow, rivers, forests, fire, wildlife and fish," said...

Bioinformaticians examine new genes the moment they are born

As most of us have learned at school, organisms evolve gradually due to the accumulation of many small genetic changes known as point mutations. Over millions of years, these mutations occur in the duplicated copies of established genes, occasionally contributing useful properties of their own. For decades it was considered inconceivable that completely novel genes...
