Threatened Alabama snail renamed after a case of mistaken identity

Thu, 14 Sep 17 00:10:00 -0700

Confusion surrounding the identity of the Painted Rocksnail, a species listed as federally threatened, has been cleared up after over 100 years of mistaken identity. Dr. Nathan Whelan and his collaborators determined that reports of the Painted Rocksnail outside the Coosa River system in Alabama were misidentifications. They found that the species is rarer and more restricted than previously thought. The study was published in the open access journal ZooKeys.



New research suggests bird songs isolate species

Wed, 13 Sep 17 00:03:40 -0700

Two birds that look the same, but have songs so different they can't recognize each other, should be considered distinct species, suggests new research. Among 72 related populations of Central and South American birds the researchers tested, they found evidence for 21 new species.



South Africa's long-legged bees adapted to pollinate snapdragon flowers

Wed, 13 Sep 17 00:02:30 -0700

New research shows that, in an extraordinary case of adaptation, the disproportionately long front legs of South Africa's oil-collecting Rediviva bee species have evolved in response to the equally long oil-producing spurs of snapdragons.



Scientists track the brain-skull transition from dinosaurs to birds

Mon, 11 Sep 17 00:16:00 -0700

The dramatic, dinosaur-to-bird transition that occurred in reptiles millions of years ago was accompanied by profound changes in the skull roof of those animals -- and holds important clues about the way the skull forms in response to changes in the brain -- according to a new study. It is the first time scientists have tracked the link between the brain's development and the roofing bones of the skull.



Fathers can influence the sex of their offspring, scientists show

Mon, 11 Sep 17 00:02:00 -0700

It has traditionally been thought that in mammals only mothers are able to influence the sex of their offspring. But a new study in wild mice led by Dr Aurelio Malo of Oxford University's Department of Zoology has shown that fathers can, in fact, influence sex ratios.



New porcelain crab species from Colombia named

Thu, 07 Sep 17 00:08:20 -0700

New, hairy-clawed porcelain crab species discovered in the southern Caribbean.



Sense of smell is key factor in bird navigation, new study shows

Tue, 29 Aug 17 00:04:20 -0700

How do birds navigate over long distances? This complex question has been the subject of debate and controversy among scientists for decades, with Earth's magnetic field and the bird's own sense of smell among the factors said to play a part. Now, researchers from the universities of Oxford, Barcelona and Pisa have shown in a new experiment that olfaction -- or sense of smell -- is almost certainly a key factor in long-distance oceanic navigation, eliminating previous misgivings about this hypothesis.



Shocking gaps in basic knowledge of deep sea life

Mon, 21 Aug 17 00:11:50 -0700

Human interference in the deep sea could already be outpacing our basic understanding of how it functions. As a result, without increased research and an immediate review of deep ocean conservation measures, the creatures that live there face an uncertain future, Oxford University scientists have warned.

The 'yellow crazy ant' lays trophic eggs to provide nutrition to their larvae.



Good grief! Losing a friend brings wild birds closer together

Wed, 17 May 17 00:05:20 -0700

New Oxford University research has revealed that instead of grieving, wild birds appear to adjust to the loss of a flockmate by increasing both the number and intensity of their relationships with other birds.



How poison frog tadpoles escape their cannibalistic siblings

Mon, 15 May 17 00:06:30 -0700

Poison frog tadpoles are dependent on parent for transportation, which helps them become separated from their cannibalistic siblings. A new study found that if all tadpoles hatch into the same pool and an adult frog enters it, tadpoles are highly attracted to the adult and try to mount it in order to escape their siblings -- even if the frog does not show any willingness to conduct transportation behaviors.



How do fishes perceive their environment?

Wed, 03 May 17 00:12:00 -0700

Fishes perceive changes in water currents caused by prey, conspecifics and predators using their lateral line. The tiny sensors of this organ also allow them to navigate reliably. However, with increasing current velocities, the background signal also increases. Scientists at the University of Bonn have now created a realistic, three-dimensional model of a fish for the first time and have simulated the precise current conditions. The virtual calculations show that particular anatomical adaptations minimize background noise.



Long lost monitor lizard 're-discovered' on Papua New Guinean island

Tue, 02 May 17 00:12:10 -0700

Scientists have recently found and re-described a monitor lizard species from the island of New Ireland in northern Papua New Guinea. It is the only large-growing animal endemic to the island that has survived until modern times. The lizard, Varanus douarrha, was already discovered in the early 19th century, but the type specimen never reached the museum where it was destined as it appears to have been lost in a shipwreck.



For a green alga, spotted salamanders are stressful hosts

Tue, 02 May 17 00:06:30 -0700

New research shows how two drastically different organisms -- a green alga and the spotted salamander -- get along as cellular roommates. Scientists at the American Museum of Natural History and Gettysburg College found that this symbiosis, the only known example that includes a vertebrate species, puts stress on algal cells, changing the way they make energy, but does not seem to negatively impact salamander cells.



Thought Antarctica's biodiversity was doing well? Think again

Tue, 25 Apr 17 00:04:40 -0700

Antarctica and the Southern Ocean are not in better environmental shape than the rest of the world.



Fish cooperate for selfish reasons

Wed, 19 Apr 17 00:16:00 -0700

Why do animals help raise offspring that aren't their own? A new study by an international team of researchers from Sweden, Canada and the UK shows that fish cooperate to raise another fish's offspring to reduce their own risk of being eaten by a predator.



Homing pigeons share our human ability to build knowledge across generations

Tue, 18 Apr 17 00:14:50 -0700

Homing pigeons may share the human capacity to build on the knowledge of others, improving their navigational efficiency over time, a new Oxford University study has found. The ability to gather, pass on and improve on knowledge over generations is known as cumulative culture. Until now humans and, arguably some other primates, were the only species thought to be capable of it.



Puffins that stay close to their partner during migration have more chicks

Fri, 07 Apr 17 00:01:20 -0700

Puffin pairs that follow similar migration routes breed more successfully the following season, a new Oxford University study has found.



Whiteflies provide insight into stabilizing manmade drones during takeoff

Wed, 05 Apr 17 00:03:10 -0700

Evolutionary advantage of the common periwinkle

Fri, 24 Mar 17 00:14:20 -0700

A special kind of small sulfur-rich proteins, the metallothioneins, have an extraordinarily large capability for binding heavy metals. An international team of scientists has now discovered that the marine common periwinkle, which is widely considered a delicacy, contains the largest version of the protein found yet, with one additional cadmium-binding domain and a one-third higher detoxification capacity. As they report in the journal Angewandte Chemie, this feature may help the snail survive in heavy-metal-polluted environments.

Using dogs to find cats

Thu, 23 Feb 17 00:03:10 -0800

Investigators are using specially-trained detection dogs to determine the numbers and distribution of cheetah in a region of Western Zambia. The research represents the first demonstration of this strategy for wide-ranging species that are often threatened.



Blood ties fuel cooperation among species, not survival instinct

Wed, 22 Feb 17 00:15:30 -0800

A new Oxford University study has found that survival instinct does not influence species cooperative breeding decisions. Instead, it has found communal living and helping behavior, to be a natural result of monogamous relationships reinforcing stronger genetic bonds in family groups. Siblings with full biological ties are more likely than others to stay with their family, than they are to break away. This is particularly beneficial in harsh environments, like the desert, but not the overall reason why they choose to live in this way.



UT mole study shows anyone can be backyard scientist

Mon, 20 Feb 17 00:02:10 -0800

Scientific findings are awaiting discovery in your backyard. The requirement? A keen sense of observation and patience.
