Amphibians, Dinosaurs Were The New Large Predators After The Mass Extinction
2014-03-20 12:37:13

University of Zurich 252 million years ago the largest extinction event occurred at the end of the Permian age. It wiped out almost 90 percent of all life in water. So far researchers had assumed that the ecosystems gradually recovered from this catastrophe over a long stretch of eight to nine million years and that large predators at the uppermost end of the food chain were the last to reappear. A Swiss-American team of palaeontologists headed by Torsten Scheyer and Carlo Romano from the...

Ecosystems Suffer Negative Effects From Loss Of Large Predators
2014-01-10 03:27:19

[ Watch the Video: Global Consequences Of Predator Loss ] Brett Smith for redOrbit.com - Your Universe Online Authors of a new research review in the journal Science have called for a global initiative to save large predators around the world. "Globally, we are losing our large carnivores," emphasized William Ripple, an author of the review and ecology professor at Oregon State University. "Many of them are endangered," he said. "Their ranges are collapsing. Many of these animals...

Smaller Islands Have Shorter Food Chains
2013-11-22 09:07:08

University of Helsinki That smaller islands will typically sustain fewer species than large ones is a widespread pattern in nature. Now a team of researchers shows that smaller area will mean not only fewer species, but also shorter food chains. This implies that plant and animal communities on small islands may work differently from those on large ones. Top predators the first to go Working across a set of 20 islands off the Finnish coast, a group of Finnish scientists found that a...

Dragonfly Study Shows How Ecosystem Changes Affect Biodiversity
2013-08-14 07:22:29

April Flowers for redOrbit.com - Your Universe Online Rice University researchers have found that communities in nature are likely to be a lot more sensitive to change than previously thought. The study findings, published in Nature Communications, points to a need for scientists concerned with human impact on the biosphere to take a different look at the consequences of altering the dynamics of a population. One example of such alteration would be removing large members of a species...

Yellowstone Elk The Focus Of Ecology Forum
2013-07-01 05:14:07

Alan McStravick for redOrbit.com - Your Universe Online Ecologists have been active in their response to the publishing of a new study in the June issue of the Ecological Society of America's journal Ecology. In it, Arthur Middleton and fellow researchers from the University of Wyoming, the Wyoming Game and Fish Department and the US Geological Survey discussed the Clarks Fork herd residing on crowded winter grounds outside of Cody, Wyoming. Their findings contradict those of a 1988 study...

Grizzly Bear Recovery Estimates Flawed, Population May Be In Decline
2013-06-25 07:19:23

Lawrence LeBlond for redOrbit.com - Your Universe Online Yellowstone grizzly bears were first given endangered species status in 1973 after extensive hunting and killing had decimated the wild populations of this apex predator. Through the years since, the populations of these grizzlies have been closely monitored by the US Fish and Wildlife Service (FWS), with numbers reportedly rebounding from a mere 200 animals in the 1970s to more than 700 today. The steady increase in grizzly...

Effects Of Predators On Carbon Cycle
2013-06-18 09:44:57

April Flowers for redOrbit.com - Your Universe Online The predator-prey relationship can affect the flow of carbon through an ecosystem, according to a new study from the Yale School of Forestry & Environmental Studies. The findings, published in Proceedings of the National Academy of Sciences, may offer a new way of looking at biodiversity management and carbon storage for climate change. The study examines the relationship between grasshoppers (herbivores) and spiders (predators)...

Italian Wolf Prefers Wild Boar Say Researchers
2012-12-21 10:59:11

Brett Smith for redOrbit.com - Your Universe Online New research from a group of British scientists has provided a more detailed look into the selective diet of wolves living in northwestern Italy. Wolves are an apex predator across Europe and the new insights could translate into more informed conservation strategies for policymakers as well as better protective measures for the region´s livestock industry, which can be affected by wolf predation. According to the...

Image 1 - Salmon, Other Fish Predators Rely On 'No Guts, No Glory' Survival Tactic
2011-09-18 05:36:09

  The phrase "no guts, no glory" doesn't just apply to athletes who are striving to excel. Salmon and other fish predators take the adage literally, by having up to three times the "gut" capacity they need on a daily basis just so they can "glory" when prey is abundant, University of Washington researchers have discovered. It's a previously unrecognized survival tactic that might apply to other top predators, such as wolves, lions and bears, according to Jonathan Armstrong, a UW...

Wolves Could Help Recovery Of Canada Lynx
2011-08-31 05:39:58

  As wolf populations grow in parts of the West, most of the focus has been on their value in aiding broader ecosystem recovery — but a new study from Oregon State University also points out that they could play an important role in helping to save other threatened species. In research published August 30 in Wildlife Society Bulletin, scientists suggest that a key factor in the Canada lynx being listed as threatened under the Endangered Species Act is the major decline of...
