The findings highlight a rural-urban divide and show that ranchers’ access to water was neither equal nor valued during the drought in Mexico’s Baja California Sur state from 2006 to 2012.
Researchers who confirmed in recent years that salmon use the Earth’s geomagnetic field to guide their long-distance migrations have found that the fish also use the field for a much simpler and smaller-scale migration: When the young emerge from gravel nests to reach surface waters.
A new blood test called the Tick-Borne Disease Serochip (TBD Serochip) promises to revolutionize the diagnosis of tick-borne disease by offering a single test to identify and distinguish between Borrelia burgdorferi, the pathogen responsible for Lyme disease, and seven other tick-borne pathogens.
Researchers have shown that the bacterial communities in termite guts came about through both inheritance and transfer between colonies.
Butterflies offer key insights into community ecology, how species originate and evolve, climate change and interactions between plants and insects. But a comprehensive map of how butterflies are related to each other has been lacking — until now.
The antioxidant drug ebselen can prevent sexual transmission of Zika virus from male to female mice, according to new research. The results hint at a potential role for ebselen in preventing Zika spread among humans.
Over a 16-year period, about half of the orangutans living on the island of Borneo were lost as a result of changes in land cover. That’s according to estimates showing that more than 100,000 of the island’s orangutans disappeared between 1999 and 2015.
Scientists have now found that beewolves, unlike humans, do not face the problem of antibiotic resistant pathogens. These insects team up with symbiotic bacteria which produce up to 45 different antibiotic substances to protect their offspring against mold fungi. This antibiotic cocktail has remained surprisingly stable since the symbiosis emerged, about 68 million years ago.
On the tail of California’s most destructive and expensive year of firefighting ever, it might seem obvious that vegetation removal would reduce the risk of such a year happening again. But scientists are showing that in chaparral, California’s iconic shrubland ecosystem, management can devastate wild bird populations and that fire-risk reduction is only temporary.
Temporary lakes and ponds emit CO2 all year –- even when they are dry — and dry areas actually emit a larger amount of carbon into the atmosphere. This phenomenon, described now for the first time, could have an impact on the global carbon cycle that controls Earth’s climate, according to a new study.
