Monitor climate change, not predators, to protect lake diversity: Study

Fri, 23 Mar 18 00:01:50 -0700

Climate change and other environmental factors are more threatening to fish diversity than predators, according to new research from the University of Guelph. It is a surprising and important finding, as humans rely upon freshwater lakes for more than one-fifth of their protein needs worldwide, says lead author Prof. Andrew MacDougall in U of G's Department of Integrative Biology.

Freeloading orchid relies on mushrooms above and below ground

Thu, 22 Mar 18 00:00:10 -0700

The orchid species Gastrodia pubilabiata mimics rotting mushrooms or fermented fruit, and is pollinated by fruit flies who mistakenly lay their eggs in its flowers. If there are rotting mushrooms near the orchid, its pollination rate increases. As well as using mushrooms to attract insect pollinators, G. pubilabiata survives by absorbing nutrients from the fungal hyphae of mushrooms. This is the first time a plant has been discovered to depend on mushrooms both above and below ground.

Physical disability boosts parenting effort, beetles study shows

Thu, 22 Mar 18 00:01:20 -0700

Animals that carry a physical impediment can work harder to rear their young as a result, an insect study has shown. They may behave this way in case they are not able to reproduce again, scientists suggest.

Deep impact: Deep-sea wildlife more vulnerable to extinction than first thought

Thu, 22 Mar 18 00:11:50 -0700

The existence of the unusual yeti crabs (Kiwaidae) -- a family of crab-like animals whose hairy claws and bodies are reminiscent of the abominable snowman -- since 2005, but already their future survival could be at risk. New Oxford University research suggests that past environmental changes may have profoundly impacted the geographic range and species diversity of this family. The findings indicate that such animals may be more vulnerable to the effects of human resource exploitation and climate change than initially thought.

The curse of zombie fossils

Wed, 21 Mar 18 00:09:40 -0700

New genetic test detects manatees' recent presence in fresh or saltwater

Mon, 19 Mar 18 00:00:00 -0700

US Geological Survey scientists have developed the first laboratory test that picks up traces of manatees' genetic material in waterways. The environmental DNA test shows whether one or more of the elusive marine mammals has been in the area in the past month.

Paraplegic rats walk again after therapy, now we know why

Mon, 19 Mar 18 00:11:10 -0700

Paraplegic rats walk again in response to neuroprosthetic rehabilitation that allows the brain to elaborate new routes so that motor commands about walking, swimming and even climbing staircases reach spinal cord execution centers below the injury.

Agriculture initiated by indigenous peoples, not Fertile Crescent migration

Mon, 19 Mar 18 00:00:30 -0700

Small scale agricultural farming was first initiated by indigenous communities living on Turkey's Anatolian plateau, and not introduced by migrant farmers as previously thought, according to new research by the University of Liverpool.

Type 2 Diabetes research held back by animal models

Mon, 19 Mar 18 00:08:50 -0700

Using animal models for researching type 2 diabetes mellitus (T2DM) impedes scientific breakthroughs about the disease origins and treatment options. Researchers recently proposed a human-centered research framework to study the biology of sugar metabolism in humans from molecules to population studies by utilizing novel human-based research technologies such as organ-on-chips and computer simulations.

Elusive venomous mammal joins the genome club

Fri, 16 Mar 18 00:15:50 -0700

An article published in GigaScience presents a draft genome of a small shrew-like animal, the venomous Hispaniolan solenodon. This unusual animal is one of the only extant venomous mammals, and it is the sole remaining branch of mammals that split from other insectivores at the time of the dinosaurs. The solenodon genome sequence revealed the answer to several evolutionary questions, such as whether the solenodon species indeed survived the meteor impact that killed the dinosaurs.

Mice change their appearance as a result of frequent exposure to humans

Fri, 16 Mar 18 00:02:20 -0700

Many tame domesticated animals have a different appearance compared to their relatives in the wild, for example white patches in their fur or shorter snouts. UZH researchers have now for the first time shown that wild house mice develop the same visible changes -- without selection, as a result of exposure to humans alone.

Thu, 15 Mar 18 00:12:10 -0700

Efforts to sustainably manage fisheries will also reduce bycatch, a new study suggests.

Reducing collateral damage

Thu, 15 Mar 18 00:13:30 -0700

A study finds that ending overfishing would stop the population declines of endangered bycatch species about half the time

Decreased oxygen levels could present hidden threat to marine species

Wed, 14 Mar 18 00:12:20 -0700

In research published in Nature Scientific Reports, scientists from the University of Plymouth have shown that creatures which develop in hypoxic (low oxygen) conditions in the marine environment could experience previously unseen hindered development, and become compromised as adults.

Fussy eating prevents mongoose family feuds

Wed, 14 Mar 18 00:13:40 -0700

Mongooses living in large groups develop 'specialist' diets so they don't have to fight over food, new research shows.

Hunger guides mountain lions' actions to enter residential areas

Tue, 13 Mar 18 00:05:00 -0700

In a new study, researchers found that while big cats like mountain lions are generally fearful of and avoid humans, hunger can dampen that fear.

Feeding wildlife can influence migration, spread of disease

Tue, 13 Mar 18 00:09:40 -0700

Animal migration patterns are changing as humans alter the landscape, according to new research from the University of Georgia. Those changes can affect wildlife interactions with parasites-with potential impacts on public health and on the phenomenon of migration itself.

do spacecraft, newborns and endangered shellfish have in common?

Tue, 13 Mar 18 00:11:10 -0700

Researchers at University of California San Diego School of Medicine have developed a microbial detection technique so sensitive that it allows them to detect as few as 50-100 bacterial cells present on a surface. What's more, they can test samples more efficiently -- up to hundreds of samples in a single day.

Die-off of fur seal pups attributed to mites, pneumonia and changing sea temperatures

Tue, 13 Mar 18 00:11:00 -0700

Morris Animal Foundation-funded researchers uncovered several key factors contributing to a die-off of South American fur seal pups, including mites, pneumonia and sea surface temperature. The findings, published in the Journal of Wildlife Diseases, help scientists better understand the link between environmental factors and health.

Life in the fast flow: Tadpoles of new species rely on 'suction cups' to keep up

Mon, 12 Mar 18 00:05:20 -0700

The young of two new species and a genus of frog found to inhabit Sumatra's rainforests have developed a unique ability to latch onto rocks in the fast-flowing rivers, using bellies crafted by evolution into 'suction cups'. The herpetologists, who described the species in the open access journal Zoosystematics and Evolution, use their remarkable discovery to highlight the unique biodiversity of the island, which is under imminent threat due to rampant habitat modification and deforestation.

Early warning system for deadly amphibian pathogen

Mon, 12 Mar 18 00:07:50 -0700

Environmental DNA is a new technology that detects telltale bits of genetic material that living creatures shed into their environment. WSU scientists demonstrate for the first time that it can be used to detect the presence of a deadly pathogen before it wipes out populations of amphibians.

Digging up the precambrian

Mon, 12 Mar 18 00:12:10 -0700

The agronomic revolution, when animals started to burrow seafloor sediments and dramatically altered the marine ecosystem, began earlier than previously thought. Researchers identified multiple specimens of the trace fossil Arenicolites from the late Ediacaran (Precambrian) of Western Mongolia. These traces were likely made by worm-like bilaterians to escape predation. This important evolutionary innovation therefore did not occur globally in the earliest Cambrian, as previously thought, but emerged earlier in at least this location.

How the color-changing hogfish 'sees' with its skin

Mon, 12 Mar 18 00:10:10 -0700

The hogfish can go from white to reddish in milliseconds as it adjusts to shifting conditions in the ocean. Scientists have long suspected that animals with quick-changing colors don't just rely on their eyes to tune their appearance to their surroundings -- they also sense light with their skin. But exactly how remains a mystery. A study reveals that hogfish skin senses light differently from eyes.

Meal times may be key to managing malaria, parasite study shows

Fri, 09 Mar 18 00:11:30 -0800

Malaria infections might be brought under control by managing the meal times of infected people or animals, a study suggests.

Serotonin promotes perseverance

Thu, 08 Mar 18 00:08:30 -0800

It was thought that the neurotransmitter serotonin most likely acted by inhibiting behavior. Now, scientists at the Champalimaud Centre for the Unknown have shown that general idea to be wrong.

Social stress leads to changes in gut bacteria, study finds

Thu, 08 Mar 18 00:06:10 -0800

Exposure to psychological stress in the form of social conflict alters gut bacteria in Syrian hamsters, according to a new study by Georgia State University.

When it comes to fuel efficiency, size matters for hummingbirds

Wed, 07 Mar 18 00:12:10 -0800

New research finds that larger hummingbirds show better mechanochemical efficiency -- the first time this has been observed in birds

Animals shield their families from a harsh world

Wed, 07 Mar 18 00:15:40 -0800

Animals living in volatile habitats can gain major evolutionary benefits by shielding their families from the changing environment, new research suggests. Biologists from the University of Bristol, the University of Exeter and UCL investigated an overlooked reason for widespread cooperation amongst animals. In a study published today in Nature, the team showed that when the environment is prone to fluctuate unexpectedly, staying at home to help raise relatives can be much better than going solo.

Guidelines needed for use of therapy animals in mental health treatment

Wed, 07 Mar 18 00:07:50 -0800

Therapy animals are used in the treatment of both mental and physical health issues, however this important form of therapy is not regulated, which leaves it open to misuse and misunderstanding by those who deliver it and the wider community.

Without 46 million year-old bacteria, turtle ants would need more bite and less armor

Tue, 06 Mar 18 00:16:10 -0800

Socially transmitted, nitrogen-providing microbes have opened a new ecological frontier for herbivorous turtle ants.

Research brief: Shifting tundra vegetation spells change for arctic animals

Tue, 06 Mar 18 00:10:40 -0800

Chimpanzees help researchers improve machine learning of animal simulations

Tue, 06 Mar 18 00:02:40 -0800

Researchers at The University of Manchester are using computer simulations of chimpanzees to improve not only our understanding of how the animals walk, but also the technology we use to do it.

A leopard may not change its spots but venomous creatures change their venom recipe often

Mon, 05 Mar 18 00:01:30 -0800

For a long time scientists believed that an animal's venom was consistent over time. However, through a close study of sea anemones, Dr. Yehu Moran of Hebrew University found that animals change their venom several times over the course of a lifetime, adapting the potency and makeup of their venom to suit changing predators and aquatic environments.

Repeated anesthesia in infancy increases anxiety-linked behavior in nonhuman primates

Thu, 01 Mar 18 00:06:10 -0800

Animals exposed to anesthesia 3x in infancy later displayed increased anxiety-linked behaviors such as scratching, self-touching and self-grooming when under mild stress.

In-depth mineral review provides foundational resource for dairy scientists
Life is dependent on minerals. Accordingly, the diets of animals must contain certain minerals in both large amounts, via marcrominerals, and small amounts, via microminerals. In a thorough and wide-ranging review published in the Journal of Dairy Science
