A mother's diet is largely responsible for keeping animal populations in check, according to a new study from the University of Edinburgh
Among the insects known as burying beetles, females are more attracted to smaller males because they are, you know, chill. That is, they're less likely to get into fights when competing for mates. Despite their increased sex appeal, however, smaller males are not necessarily better parents, researchers reveal in a new study.
Millions of lab mice suffer from an infectious skin disease known as ulcerative dermatitis. However, researchers from Stanford University have come up with a novel cure – pedicures – that is cost effective and keeps the rodent subjects from having to be euthanized, the ultimate plus for reseachers.
Along with visual camouflage, Puff adders have evolved a scent camouflage that makes them virtually undetectable to predators. Researchers say these African vipers are the first terrestrial vertebrates known to possess the ability to camouflage their scent.
In a 2014 survey of Morocco's island of Mogador, raptors called Eleonora's falcons were observed engaging in a what researchers called a new behaviour that ensures their offspring receive the freshest of meats: imprisoning smaller live birds before killing and feeding them to their young several days later.
Three adult piping plovers nested along New York's Lake Ontario shoreline for the first time in over 30 years. Among the birds was a breeding pair that successfully fledged a single chick – a promising step in the recovery of the endangered bird's Great Lakes population.
Following the arrival of gentoo penguins along the West Antarctic Peninsula, native Adelie penguins have experienced population declines. However, researchers are unsure whether increased food competition among the two species or climate change is ultimately to blame.
When a one-ton giant manta ray with a wingspan of 23 feet was caught last year in gill nets made by Peruvian fisherman, conservationists called for action. These treasured marine creatures are particularly vulnerable to overfishing and bycatch.
West Indian manatees have rebounded in Florida, prompting the U.S. Fish and Wildlife Service to downlist the species from endangered to threatened.
A hunted male mountain lion was found to have a full set of teeth and whiskers growing out of its head. Experts say this bizarre growth could be the remnants of a conjoined twin that died in the womb or possibly a kind of rare tumour.
A new dual-cropping plant named "Egg and Chips" grows four eggplants from its stem and over four pounds of potatoes from its roots. Experts say this plant not only saves gardening space, but the hardy potato plants actually support the eggplants, whose roots are more delicate.
Crows are frequently observed gathering around dead comrades. When researchers from the University of Washington investigated this behavior they found the crafty birds understand much about death and the threat of death by predators, not only reacting to their fallen brethren but also avoiding areas or things they deem dangerous.
Scientists from McGill University in Montreal, Canada, recently learned a little more about the elusive marine creatures known as narwhals by focussing on newborns.
Hydroelectric dams planned for the tropical rivers of Mekong, Amazon and Congo could destroy local fish habitats and cause human populations to relocate, too. A team of researchers suggest new ways to evaluate the cost and benefits of these massive structures.
