Twitter clips human thoughts to a mere 140 characters. Animals’ scent posts may be equally as short, relatively speaking, yet they convey an encyclopedia of information about the animals that left them. (more…)
Scientists have discovered a diverse multitude of microbes colonizing and thriving on flecks of plastic that have polluted the oceans—a vast new human-made flotilla of microbial communities that they have dubbed the “plastisphere.”
In a study recently published online in Environmental Science & Technology, the scientists say the plastisphere represents a novel ecological habitat in the ocean and raises a host of questions: How will it change environmental conditions for marine microbes, favoring some that compete with others? How will it change the overall ocean ecosystem and affect larger organisms? How will it change where microbes, including pathogens, will be transported in the ocean? (more…)
EAST LANSING, Mich. — Bacteria in hyenas’ scent glands may be the key controllers of communication.
The results, featured in the current issue of Scientific Reports, show a clear relationship between the diversity of hyena clans and the distinct microbial communities that reside in their scent glands, said Kevin Theis, the paper’s lead author and Michigan State University postdoctoral researcher.
“A critical component of every animal’s behavioral repertoire is an effective communication system,” said Theis, who co-authored the study with Kay Holekamp, MSU zoologist. “It is possible that without their bacteria, many animals couldn’t ‘say’ much at all.” (more…)
