How different ant species coexist in the same territory

Thu, 09/28/2017 - 12:22

In every animal community, several species in the same group share habitats. An international team has chosen ants to create the largest public-access database on the cohabitation of these insects. The goal is to understand their tricks for coexistence and how they respond to invasive species and climate change.

Saber-toothed kittens may have been born with thicker bones than other contemporary cats

Thu, 09/28/2017 - 09:17

Saber-toothed kittens may have been born with thicker bones compared to other contemporary cats, but they have a similar pattern of bone development, according to a new study.

Emerging infectious disease threatens Darwin’s frog with extinction

Wed, 09/27/2017 - 07:09

Iconic species likely to be wiped-out by amphibian fungus, despite lack of obvious short-term evidence.

Moths: A different weapon against each enemy

Wed, 09/27/2017 - 06:56

It's a dangerous world out there, especially if you are a small insect. Insects have thrived on our planet for hundreds of millions of years, so they must be doing something right despite all the threats to their survival. With so many predators out to get them many animals have evolved chemical defences, making themselves distasteful or even toxic. Wood tiger moths protect themselves from multiple predators using different chemical defences. Choosing the right defence can be tricky as predators come in many forms, and from many directions.

Tree-dwelling, coconut-cracking giant rat discovered in Solomon Islands

Wed, 09/27/2017 - 06:33

Scientists have discovered a new species of giant rat. It's more than four times the size of the black rats that live in the US, it lives in trees, and it's rumored to crack open coconuts with its teeth. And it's actually pretty cute.

Noise pollution found to be disruptive for schooling fish

Tue, 09/26/2017 - 20:59

Noise from human construction projects can disrupt the schools that are so impressive in marine fish, new research has found.

Caribbean praying mantises have ancient African origin

Tue, 09/26/2017 - 20:59

Three seemingly unrelated praying mantis groups inhabiting Cuba and the rest of the Greater Antilles actually share an ancient African ancestor and possibly form the oldest endemic animal lineage on the Caribbean islands, researchers have determined.

Discovery: Bernie Sanders spider

Tue, 09/26/2017 - 07:55

Students and a scientist have discovered 15 new species of 'smiley-faced' spiders -- and named them after, among others, David Attenborough, Barack Obama, Michelle Obama, Leonardo DiCaprio, and Vermont Senator Bernie Sanders.

Chronic wasting disease

Tue, 09/26/2017 - 07:54

New research summarizes the efforts in disease surveillance and risk management of chronic wasting disease (CWD) in deer and shows that past management strategies such as selective culling, herd reduction, and hunter surveillance have had only limited effectiveness. The summary points towards new advice for optimal, cost-effective strategies in aggressive disease control.

Penguin-mounted video captures gastronomic close encounters of the gelatinous kind

Mon, 09/25/2017 - 13:32

Footage from penguin-mounted mini video recorders shows four species of penguin eating jellyfish and other gelatinous animals of the open ocean, a food source penguins were not previously believed to partake of, scientists report.

Ticks are even tougher and nastier than you thought

Mon, 09/25/2017 - 10:30

Studies are showing how ticks can survive drought and cold northern winters.

Panda habitat shrinking, becoming more fragmented

Mon, 09/25/2017 - 08:13

Using remote sensing data, Chinese and US scientists have re-assessed the conservation status of the giant panda. Their analysis shows that while panda numbers are increasing, their habitat still covers less area and is more fragmented than it was in 1988, when the species was listed as endangered on the IUCN Red List.

The rat race is over: New livestock model for stroke could speed discovery

Mon, 09/25/2017 - 07:57

Researchers have developed the first US pig model for stroke treatments.

Scientists sequence asexual tiny worm whose lineage stretches back 18 million years

Thu, 09/21/2017 - 11:13

A team of scientists has sequenced, for the first time, a tiny worm that belongs to a group of exclusively asexual species that originated approximately 18 million years ago -- making it one of the oldest living lineages of asexual animals known.

Jellyfish, with no brains, still seem to sleep

Thu, 09/21/2017 - 11:12

The discovery that primitive jellyfish sleep suggests that sleep is an ancient, evolutionarily conserved behavior.

Heat-loving Australian ants believe in diversity, hint 74 species new to science

Thu, 09/21/2017 - 11:12

A genus of Australian ants, many of whose members prefer to forage in blistering temperatures of up to 50°C (122°F), is revised to include 74 new species. The ants include seed-eaters, ant and termite raiders, 'honeypot ants' that store nectar and honeydew, and numerous others whose biology is not yet understood. Some are bizarre: one species has eyes like inverted ice-cream cones.

Dino-killing asteroid's impact on bird evolution

Thu, 09/21/2017 - 09:11

Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants.

New hermit crab uses live coral as its home

Thu, 09/21/2017 - 07:42

A new hermit crab species can live in a walking coral's cavity in a reciprocal relationship, replacing the usual marine worm partner, according to a new study.

Researchers discover new cattle disease and prevent it from spreading

Thu, 09/21/2017 - 07:17

Following genetic studies of deformed calves, research is able to uncover a previously unknown disease found among Holstein cattle. The breeding bull from which the mutation and thus the deformation originate has now been put down to prevent the disease from spreading further.

3-D analysis of dog fossils sheds light on domestication debate

Wed, 09/20/2017 - 15:20

In an effort to settle the debate about the origin of dog domestication, a technique that uses 3-D scans of fossils is helping researchers determine the difference between dogs and wolves.
