David Orenstein, Brown University The gravity of the world’s current extinction rate becomes clearer upon knowing what it was before people came along. A new estimate finds that species die off as much as 1,000 times more frequently nowadays than they used to. That’s 10 times worse than the old estimate of 100 times. It’s hard to comprehend how bad the current rate of species extinction around the world has become without knowing what it was before people came along. The newest...

redOrbit Staff & Wire Reports - Your Universe Online Plant and animal species are becoming extinct at rates more than 1,000 times more quickly than they did before the arrival of humans, indicating that the Earth could be edging closer to a sixth great extinction, according to a new study published May 30 in the journal Science. In the study, Duke University biologist Stuart Pimm and his colleagues examined both past and present rates of extinction using the IUCN Red List of...

Rate of loss of species exceeds that of terrestrial animals North American freshwater fishes are going extinct at an alarming rate compared with other species, according to an article in the September issue of BioScience. The rate of extinctions increased noticeably after 1950, although it has leveled off in the past decade. The number of extinct species has grown by 25 percent since 1989. The article, by Noel M. Burkhead of the US Geological Survey, examines North American freshwater...

Birds In New Zealand Face Extinction

redOrbit Staff & Wire Reports - Your Universe Online Keys to survival today differ from those of the past. This is revealed in a new study of nearly 300 species of New Zealand birds – from pre-human times to the present. Lead author Lindell Bromham of Australian National University said, "Taking into consideration the growing number of studies that try to predict which species could be lost in the future based on what kinds of species are considered most threatened today the...

Demise Of Larger Prehistoric Animals Blamed On Climate Change, Humankind
2012-03-06 09:05:44

The death and extinction of many large, prehistoric animals may be due largely in part to man´s actions as well as climate change. The University of Cambridge has conducted new research to determine if humankind played a significant role in the destruction of these prehistoric megafauna. The findings were posted on March 5, 2012 in the journal PNAS. The research team examined extinctions during the late Quaternary period (700,000 years ago to present day) but focused much of their...

A projected wave of extinctions of plant and animal species this century may have been overestimated because the most widely used scientific method can exaggerate losses by more than 160 percent, according to a study published Wednesday in the journal Nature. The scientists said that habitat destruction by humans is driving animal and plant species toward extinction at just half the pace as previously believed. They attribute the overestimation to flaws in the most popular scientific method,...

However, researchers say, global extinction crisis remains very serious The most widely used methods for calculating species extinction rates are "fundamentally flawed" and overestimate extinction rates by as much as 160 percent, life scientists report May 19 in the journal Nature. However, while the problem of species extinction caused by habitat loss is not as dire as many conservationists and scientists had believed, the global extinction crisis is real, says Stephen Hubbell, a...

Paleobiologists at the University of California at Berkeley are studying the state of biodiversity today, using the world's mammal species as a barometer. Mammal extinctions were very rare: on average, just two species died out every million years, until humans' largest expansion yet, some 500 years ago.In the last five centuries however, at least 80 out of 5,570 mammal species have disappeared, thinning out the biodiversity of the planet. "It looks like modern extinction rates resemble mass...

Steep decline of many animal species warns that Earth is on the brink With the steep decline in populations of many animal species, scientists have warned that Earth is on the brink of a mass extinction like those that have occurred just five times during the past 540 million years. Each of these "Big Five" saw three-quarters or more of all animal species go extinct. In results of a study published in this week's issue of journal Nature, researchers report on an assessment of where mammals...

Discoveries spanning five continents and three oceans cap the United Nations' International Year of Biodiversity Global biodiversity surveys over the past few years have provided increasing evidence that our planet is in the midst of its sixth mass extinction. Plants, animals, and microorganisms are disappearing thousands of times more rapidly than they have for more than 65 million years, and for the first time in Earth's history, human activity is the predominant force behind this mass...
