Patagonian fossil leaves reveal rapid recovery from dinosaur extinction event
2016-11-07 13:00:00| LifeSciencesWorld
[NEWS] Ancient feeding marks from hungry insects in South American leaf fossils are shedding new light on the mass extinction that wiped out the dinosaurs. Scientists analyzed insect feeding damage to thousands of leaf fossils from Patagonia, Argentina, over the Cretaceous-Paleogene boundary, and found evidence that ecosystems there recovered twice as fast as in the United States. The findings, published today (Nov. 7) in the new journal Nature Ecology & …

Huffington Post: Both species of orangutan are critically endangered. Conservationists have been warning of this moment for years. Orangutans ? one of the planet's most intelligent animals ? are officially headed for extinction. The Bornean orangutan is now critically endangered, according to a species assessment published this week by the International Union for Conservation of Nature. The animal's Sumatran cousin, the other species of orangutan, was already listed as critically endangered ? meaning all orangutans...

Guardian: Whale sharks and winghead sharks have moved one step closer to extinction, after the International Union for the Conservation of Nature (IUCN) redefined them both as endangered species on the groups Red List. The two predatory species have fallen foul of increased pressure from human activity, especially the fishing industry, with populations of whale sharks the worlds largest living fish halving in the last 75 years. Jane Smart, the director of the IUCNs Global Species Programme said:...

Temperature-Induced Sex Change Could Drive This Species to Extinction

EcoWatch: Increasing temperatures due to climate change is altering the demographics of the central bearded dragon population and possibly sending the species into extinction. Like a lot of reptiles, Discovery News said, the gender of central bearded dragons depends on their chromosomes and the temperature at which the eggs are incubated. The egg is born a female when incubated at higher temperatures. Increasing global temperatures could skyrocket the number of female central bearded dragons in the future,...
Climate change 'the key to megafauna extinction'
2016-06-20 06:50:00| Climate Ark Climate Change & Global Warming Newsfeed
Cosmos: Bears the size of cars and savage sabre-toothed cats that ruled the plains of ice age Patagonia were no match for a fatal combination of humans and climate change that wiped them out about 12,300 years ago, according to a new study. But contrary to previous research, humans alone did not cause their downfall. The fossil record shows humans had been at Monte Verde, on the edge of Patagonia, from about 14,600 years ago. That means the South American megafauna had coexisted with humans for up to...
