Mass extinctions led to low species diversity, dinosaur rule
2017-10-10 06:00:00| LifeSciencesWorld
[NEWS] Two of the earth's five mass extinction events - times when more than half of the world's species died - resulted in the survival of a low number of so-called “weedy” species that spread their sameness across the world as the Earth recovered from these dramatic upheavals. The findings could shed light on modern high extinction rates and how biological communities may change in the future. David J. Button, an NC State and North Carolina Museum of Natural Sci…

Historical wildlife trends reliable for predicting species at risk
2017-08-02 06:00:00| LifeSciencesWorld
[NEWS] Some of the methods used to predict at risk species are trend-based - an indicator of what happens gradually over time - while others are trait based, which uses signs of climate change in the current environment. Mix these methods together, however, and you get an unreliable set of results, scientist have found. The researchers are calling for guidelines produced by the International Union for Conservation of Nature (IUCN) Red List, the world's main authority on …
