12-09-06 Will the tiger go the way of the passenger pigeon or be saved from extinction like the American bison? The Wildlife Conservation Society (WCS) today released a list of Asian species that are at a conservation crossroads calling for governments to ta...

12-01-10 Around 250 million years ago, at the end of the Permian geologic period, there was a mass extinction so severe that it remains the most traumatic（创伤的） known species die-off in Earth's history. Although the cause of this event is a mystery, it h...

11-11-20 It's well known that Earth's most severe mass extinction occurred about 250 million years ago. What's not well known is the specific time when the extinctions occurred. A team of researchers from North America and China have published a paper in Sci...

11-07-20 Populations of spur-thighed tortoises ( Testudo graeca欧洲陆龟 ), a species classified as vulnerable and at risk of extinction, can withstand fires if outbreaks occur once every three decades or more. However, the youngest tortoises are more vulnera...

11-07-13 A team of scientists has discovered the youngest dinosaur preserved in the fossil record before the catastrophic meteor（流星） impact 65 million years ago. The finding indicates that dinosaurs did not go extinct prior to the impact and provides fur...

11-05-19 Current extinction rate projections may be overestimating the role of habitat loss on species, a study suggest. 一项研究显示，现有物种灭绝速率预测可能高估了栖息地缺失对物种的影响。 The authors acknowledge that the study does not mean concerns for bi...

11-01-24 About 250 million years about 95 per cent of life was wiped out in the sea and 70 per cent on land. Researchers at the University of Calgary believe they have discovered evidence to support massive volcanic eruptions burnt significant volumes of coa...

11-01-03 An influx（流入，汇集） of invasive species can stop the dominant natural process of new species formation and trigger mass extinction events, according to research results published today in the journal PLoS ONE. The study of the collapse of Earth'...

10-12-23 A major new fossil site in south-west China has filled in a sizeable gap in our understanding of how life on this planet recovered from the greatest mass extinction of all time, according to a paper co-authored by Professor Mike Benton, in the Schoo...

10-12-21 Researchers from the University of Washington say the Mariana crow（乌鸦） , a forest crow living on Rota Island in the western Pacific Ocean, will go extinct in 75 years. The extinction could happen almost twice as soon as previously believed. The...
