Coral death stops fish from learning predators
In a world first study researchers have found that coral bleaching and death can have dramatic repercussions for how small reef fish learn about and avoid predators. The new results are published in the journal Proceedings of the Royal Society B. (2016-05-10)

Pest control breakthrough - from a spider's stomach
DNA found in a spider's stomach could herald a breakthrough in the fight against farm pests, which cause millions of dollars of damage to crops. Cardiff University, UK, scientists, led by Dr Bill Symondson in the School of Biosciences, have become the first to use DNA-based techniques to analyse the content of spiders' guts to identify the prey they have eaten in the field. (2003-12-12)

USF biologists: Reductions in biodiversity can elevate disease risk
Using a combination of experiments, field studies, and mathematical models, University of South Florida biologists and colleagues from four other universities show that having an abundance and diversity of predators -- such as dragonflies, damselflies, and aquatic bugs -- to eat parasites is good for the health of amphibians, a group of animals experiencing worldwide population declines. (2015-02-23)

Caterpillars aren't so bird brained after all
Caterpillars that masquerade as twigs to avoid becoming a bird's dinner are actually using clever behavioural strategies to outwit their predators, according to a new study. (2011-04-04)

Study: Death by moonlight? Not always
Is moonlight dangerous? It depends on what you are, according to a study published online recently in the Journal of Animal Ecology. (2013-10-21)

Female guppies risk their lives to avoid too much male attention
Sexual harassment is a burden that females of many species face, and some may go to extreme lengths to avoid it. Female guppies, a popular aquarium fish, may even risk their lives to avoid too much attention from males. Observing wild population of guppies in the rainforest of Trinidad, researchers found that female guppies swim in habitats that contain few males - but many predators. (2006-05-12)

Predator threat boosts friendships among guppies
Danger from predators causes animals to form stronger friendships, according to new research. (2017-02-02)

New Zealand bird outwits alien predators
New research published in this week's PLoS ONE, led by Dr. Melanie Massaro and Dr. Jim Briskie at the University of Canterbury, which found that the New Zealand bellbird is capable of changing its nesting behavior to protect itself from predators, could be good news for island birds around the world at risk of extinction. (2008-06-03)

Poor mimics can succeed as long as they mimic the right trait
There are both perfect and imperfect mimics in nature. An imperfect mimic might have a different body shape, size or color pattern arrangement compared to the species it mimics. Researchers have long been puzzled by the way poor mimicry can still be effective in fooling predators not to attack. In the journal Current Biology, researchers from Stockholm University now present a novel solution to the question of imperfect mimicry. (2014-04-10)

Research ends debate over benefits of butterfly defenses
Scientists at the University of Liverpool have furthered understanding of the relationship between predator and prey in an experiment designed to understand butterfly defence mechanisms. (2007-07-05)

Climate change could turn oxygen-free seas from a blessing to a curse for zooplankton
Zooplankton can use specialized adaptations that allow them to hide from predators in areas of the ocean where oxygen levels are so low almost nothing can survive -- but they may run into trouble as these areas expand under climate change. This work will be presented at the Society for Experimental Biology Annual Conference in Glasgow on July 1, 2011. (2011-06-30)

Wolves need space to roam to control expanding coyote populations
Wolves and other top predators need large ranges to be able to control smaller predators whose populations have expanded, according to a study appearing May 23 in Nature Communications. The results were similar across three continents, showing that as top predators' ranges were cut back and fragmented, they were no longer able to control smaller predators. (2017-05-23)

Medium-sized carnivores most at risk from environmental change
In a surprise ecological finding, researchers discover medium-sized carnivores spend the most time looking for food, making them vulnerable to change. (2017-12-04)

Sexy or repulsive? Butterfly wings can be both to mates and predators
Butterflies seem able to both attract mates and ward off predators using different sides of their wings, according to new research by Yale University biologists. (2009-04-01)

Birds of a feather flock together to confuse potential predators
Scientists from the universities of Bristol and Groningen, in The Netherlands, have created a computer game style experiment which sheds new light on the reasons why starlings flock in massive swirling groups over wintering grounds. (2017-01-17)

Fear of predators increases risk of illness
Predators are not only a deadly threat to many animals, they also affect potential prey negatively simply by being nearby. Researchers at Lund University in Sweden have studied what happens to the prey's immune system when they are forced to expend a large amount of their energy on avoiding being eaten. (2019-07-09)

Humans give prey the edge in food web
A new paper in PLoS ONE that found prey species have an advantage over predators in wilderness areas subject to human disturbance related to recreation and resource development. The study was conducted in the Rocky Mountain foothills near Calgary. (2011-03-03)

Intense look at La Brea Tar Pits explains why we have coyotes, not saber-toothed cats
The most detailed study to date of ancient predators trapped in the La Brea Tar Pits is helping Americans understand why today we're dealing with coyotes dumping over garbage cans and not saber-toothed cats ripping our arms off. (2019-08-05)

A leopard may not change its spots but venomous creatures change their venom recipe often
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. (2018-03-05)

New research on fossil whales' teeth shows they were ferocious predators
International research involving Monash biologists has provided new insights into how the feeding habits of the whale -- the biggest animal -- have evolved. (2017-08-30)

More predators doesn't equal more danger for urban bird nest
While birds living in urban areas face more predators than do those in rural areas, that doesn't mean urban birds face more danger from nest robbers. A six-year study conducted in 19 central Ohio forests from 2004 to 2009 found that, as expected, rural areas that had higher numbers of nest predators such as raccoons, domestic cats and crows, also showed lower rates of nest survival. (2010-09-23)

Will lemmings fall off climate change cliff?
Contrary to popular belief, lemmings do not commit mass suicide by leaping off cliffs into the sea. A bigger threat to the the rodents is climate change, according to the Wildlife Conservation Society, which is launching a study to examine how these tiny but important players in the ecological health of the far North will fare in the age of global warming. (2007-04-20)

Small rodents encourage the formation of scrubland in Spain
After two years of research over five degraded landscapes in the National Park of Sierra Nevada, scientists have established for the first time that field mice base their diet on holm oak and pine seeds, causing a deterioration of the habitats and an extension of scrubland in the forests. (2009-08-27)

Invasive species as junk food for predators
The one upshot to the appearance of an invasive species --that it might provide native predators with additional food --comes with some caveats. (2015-10-14)

Historical coexistence with dingoes may explain bandicoot avoidance of domestic dogs
Domestic dogs and cats were introduced to Tasmania two centuries ago, but bandicoots still fail to recognize these introduced predators as threats, according a study published Sept. 7, 2016, in the open-access journal PLOS ONE by Anke Frank from University of Tasmania, Australia, and colleagues. (2016-09-07)

What's love got to do with it? A lot for eavesdropping bats, singing katydids
A new eavesdropping study of bats and katydids by Dartmouth researchers and their collaborators provides evidence that sensory differences can influence the 'evolutionary arms race' between predators and prey. (2015-05-19)

Distressed damsels cry for help
Researchers at the ARC Centre of Excellence for Coral Reef Studies at James Cook University have found that fish release a chemical 'distress call' when caught by predators, dramatically boosting their chances of survival. (2015-10-27)

Can bird feeders do more harm than good?
Many bird lovers put out feeders full of seed for their feathered friends -- but those feeders may also attract predators that eat eggs and nestlings. The researchers behind a new study in The Condor: Ornithological Applications tried to untangle these relationships through a four-year study of songbird nests, bird feeders, and predators in urban central Ohio. (2016-12-07)

Camouflage really does reduce the chances of being eaten
The research, by scientists from the Universities of Exeter and Cambridge, investigated the camouflage of ground-nesting birds in Zambia, using sophisticated digital imaging to demonstrate how they would appear from the perspective of a predator. (2016-01-29)

Looking different 'helps animals to survive'
In the animal kingdom, everything is not as it seems. Individuals of the same species can look very different from each other -- what biologists term (2009-07-23)

Animals actively choose to match their surroundings to avoid predation
Animals can match their background to avoid detection by predators. For instance, numerous species have evolved color patterns that help them blend into their surroundings and avoid predators -- a phenomenon called crypsis. A new experimental study found that ghost crabs in the Solomon Islands may achieve crypsis by actively choosing to live in sand background that matches their body color. (2017-04-27)

UT study tackles evolution mystery of animal, plant warning cues for survival
Not every encounter between predator and prey results in death. A new study co-authored by a University of Tennessee, Knoxville, professor suggests that prey emit warning cues that can ultimately lead to both their survival and that of their predators. The hypothesis addresses a 150-year-old mystery of evolution on how warning signals of animals and plants arise and explains animals' instinctive avoidances of dangerous prey. (2015-05-27)

Prey-foraging: The collective search or lone-wolf approach?
Many predators either hunt alone keeping the spoils to themselves or in packs sharing the bounty with others. Deciding whether to tell fellow predators about some tasty prey involves weighing up many pros and cons. In a new paper published in PLOS Computational Biology, researchers from Princeton University and the Stockholm Resilience Centre found a simple 'rule of thumb' that may help unravel this complex decision-making behavior. (2016-10-20)

Mixed signals from poisonous moths
Poisonous moths use bright red spots to warn predators to avoid them -- but natural variation in these wing markings doesn't provide clear indications of how toxic individual moths might be -- new research shows. (2018-06-04)

Climate change could turn oxygen-free seas from blessing to curse for zooplankton
Zooplankton can use specialized adaptations that allow them to hide from predators in areas of the ocean where oxygen levels are so low that almost nothing can survive, but they may run into trouble as these areas expand due to climate change. (2011-07-01)

Meadow of dancing brittle stars shows evolution at work
Newly described fossil shows how brittle stars evolved in response to pressure from predators, and how an 'evolutionary hangover' managed to escape them. (2017-08-13)

Effectiveness of using natural enemies to combat pests depends on surroundings
A new study of cabbage crops in New York -- a state industry worth close to $60 million in 2017, according to the USDA -- reports for the first time that the effectiveness of releasing natural enemies to combat pests depends on the landscape surrounding the field. (2019-07-15)
