A large number of gray whales are starving and dying in the eastern North Pacific

It is now the third year that gray whales have been found in very poor condition or dead in large numbers along the west coast of Mexico, USA and Canada, and scientist have raised their concerns. An international study suggests that starvation is contributing to these mortalities.

Shift in caribou movements may be tied to human activity

(University of Cincinnati) Human activities might have shifted the movement of caribou in and near the Arctic National Wildlife Refuge, according to scientists who tracked them using isotopic analysis from shed antlers. The study is timely given the auction this year of oil and gas leases in the Arctic National Wildlife Refuge. Indigenous Alaskans opposed the leases, arguing development could disrupt the migration of caribou they depend on for sustenance.

Early breeding reduced harmful mutations in sorghum

A new Cornell University study found that harmful mutations in sorghum landraces – early domesticated crops – decreased compared to their wild relatives through the course of domestication and breeding.

Methods in studying cycad leaf nutrition found to be inconsistent and incomplete

(University of Guam) Collective research to date regarding nutrients found in the leaves of contemporary cycad species has been inconsistent as far as data collection and narrow in scope, according to a University of Guam-led literature review published on Nov. 19 in Horticulturae journal.

Embryos Created at Christmas Are Viable—Raising Hopes For the 2 Remaining Northern White Rhinos

Following up on their success of the last two years, the international collaborative effort to save the northern white rhino from extinction has extracted another 14 egg cells from Fatu, one of the two females rhinos that make up the living remainder of the species. These would end up offering two viable fertilized eggs for […]

Prenatal BPA exposure may contribute to the male bias of autism spectrum disorder

Autism has a higher prevalence in males than females. Bisphenol A (BPA) is a common chemical found in plastics, our food, and even the human placenta. Higher prenatal exposure to BPA is thought to increase the risk of autism. Researchers have identified autism candidate genes that may be responsible for the sex-specific effects of BPA.

With a little help from their friends, older birds breed successfully

(University of Groningen) The offspring of older animals often have a lower chance of survival because the parents are unable to take care of their young as well as they should. The Seychelles warbler is a cooperatively breeding bird species, meaning that parents often receive help when raising their offspring. A study led by biologists from the University of Groningen shows that the offspring of older females have better prospects when they are surrounded by helpers.
