Super predators and mass extinctions
Mass extinctions seem to occur on Earth roughly every 26 million years, leading some scientists to propose that they may be caused by rare collisions with comets or asteroids. A researcher in Poland thinks it may be possible that extraordinary predators are at fault instead. Adam Lipowski (Adam Mickiewicz University) constructed a numerical model of many species competing for both food and...New study pinpoints epicenters of Earth's imminent extinctions
Safeguarding 595 sites around the world would help stave off an imminent global extinction crisis, according to new research published today in the Proceedings of the National Academy of Sciences ( Conducted by scientists working with the 52 member organizations of the Alliance for Zero Extinction (AZE –?<A HREF="http://www.zeroextinction.org...Extinctions linked to climate change
A new report that links global warming to the recent extinction of dozens of amphibian species in tropical America is more evidence of a large phenomena that may affect broad regions, many animal species and ultimately humans, according to researchers at Oregon State University. A study being published Thursday in the journal Nature finds compelling evidence that global climate change crea...Climate change drives widespread amphibian extinctions
Results of a new study provide the first clear proof that global warming is causing outbreaks of an infectious disease that is wiping out entire frog populations and driving many species to extinction. Published in the Jan. 12 issue of the journal Nature, the study reveals how the warming may alter the dynamics of a skin fungus that is fatal to amphibians. The climate-driven fungal disease...Man may have caused pre-historic extinctions
New research shows that pre-historic horses in Alaska may have been hunted into extinction by man, rather than by climate change as previously thought. The discovery by Andrew Solow of Woods Hole Oceanographic Institute, US, David Roberts of the Royal Botanic Garden, Kew and Karen Robbirt of the University of East Anglia (UEA) is published this week in Proceedings of the National Academy o...
