big brown bat in flight
2014-03-29 05:33:03

redOrbit Staff & Wire Reports - Your Universe Online While experts have long known that bats use ultrasonic calls to locate insect prey, research published earlier this week reveals that males have a second distinctive set that essentially allows them to call dibs on a potential meal. The new study, which appears in Thursday’s edition of the journal Current Biology, explained that there is a correlation between these special sounds and changes in the flight behavior of other bats....

New Computer Model Could Preserve The World's Bee Colonies
2014-03-04 15:25:51

Lee Rannals for redOrbit.com - Your Universe Online Scientists have created a new computer model to help understand the environmental effects of a honeybee colony. The BEEHAVE model published in the Journal of Applied Ecology was created to investigate the losses of honeybee colonies that have been reported recently and to identify the best way to try and combat the losses. [ Watch the Video: BEEHAVE Model ] "It is a real challenge to understand which factors are most important in...

Video Footage Reveals Novel Insights Into Crocodilian Foraging Behaviors

Public Library of Science Animal-borne camera reveals that alligators may attempt to capture prey most often at night, even though the calculated probability of catching prey is highest in the morning, according to a study published in PLOS ONE on January 15, 2014 by James Nifong from the University of Florida and colleagues from other institutions. Observing the behaviors of dangerous and cryptic predators like alligators is no easy task, so scientists used animal-borne cameras to...

Sandpipers Exhibit Different Feeding Behavior Depending On Position In Group
2013-10-28 11:52:55

University of Montreal The behavior of semipalmated sandpipers (Calidris pusilla) feeding during low tide in the Bay of Fundy, New Brunswick, surprised Guy Beauchamp, an ornithologist and research officer at the University of Montreal's Faculty of Veterinary Medicine. While individuals on the periphery remained alert and used short pecks to feed on the mudflats, birds in the middle of the group relaxed their vigilance and fed on a different resource. The more peripheral group members were...

Shy Male Birds Likely To Flock Together And Have Fewer Friends
2013-09-18 12:11:31

University of Oxford Male birds that exhibit 'shy' social behavior are much more likely to join flocks of birds with a similar personality than their 'bold' male counterparts, a new study has found. But shy birds also have fewer social partners than bold birds. The research, carried out by scientists from Oxford University and the Australian National University, used a new way of analyzing the social networks that link individual animals to each other – a kind of 'Facebook for birds'...

Noise Of Passing Ships Disrupts Feeding For The Common Shore Crab
2013-07-11 12:23:52

University of Exeter A study published in the journal Animal Behaviour found that the noise of passing ships disrupts feeding for the common shore crab. Perhaps worse, the team from the Universities of Exeter and Bristol also found that when threatened, crabs took longer to retreat to shelter and lost their natural 'play dead' behavior. In coastal seas around the world noise caused by humans is a dominant feature, with construction and transportation fundamentally modifying ocean...

The novel Natural Sciences Bibliographic Web Portal aims to provide comprehensive bibliographic information on the basic and applied life, earth and health sciences and has published over 244,800 references and 161,400 tags. Scien.net has now newly included the category ecology, which is the scientific study of the relationships that various living organisms have with each other, as well as their relationships with their natural environment, and on forage which is the plant material eaten by...

Changing Eating Habits Of The Hawaiian Petrel And Other Sea Birds Concern Scientists
2013-05-14 08:29:00

redOrbit Staff & Wire Reports - Your Universe Online Changes in the eating habits of endangered Hawaiian petrels have scientists concerned about the impact that the growth of industrialized fishing will have not only on the seabirds but upon other species of animals as well. Researchers from Michigan State University (MSU) and the Smithsonian Institution (SI) looked at both ancient and modern remains of the birds, which spent much of their lives foraging for food in the Pacific...

Researchers Discover New Migration Habits Of Manx Shearwater Seabird
2013-05-01 10:35:22

Brett Smith for redOrbit.com - Your Universe Online Using cutting-edge tracking devices and data analysis techniques, a group of UK researchers has discovered new migration habits of the Manx Shearwater, a small seabird. Scientists at the University College London (UCL) and the University of Oxford collected data over three consecutive years to reveal the birds´ complex pattern of rest, flight and foraging, according to their report in journal Interface. "Understanding the...

Like birds which stop foraging too early on a berry-laden bush, a new study suggests older people struggle to recall items because they flit too often between ℠patches´ in their memories. The study by the University of Warwick published in the journal Developmental Psychology seeks to model the mechanisms behind memory decline in old age. Its findings indicate that specific changes in the way older people access their memories, rather than a general ℠slowing down´...
