BBC: Tree species in the Amazon rainforest are so many and varied that it would take three centuries to catalogue them, a major study has estimated. In research published in the journal Scientific Reports, more than 500,000 museum specimens dating back 300 years were audited. They say nearly 12,000 tree species have been discovered so far. Based on this figure, they predicted that about 4,000 rare types remained to be discovered and described. The scientists say the species list will assist...

PhysOrg: There are more different kinds of trees in the Amazon rainforest than anywhere else on earth, but the exact number has long been a mystery. In 2013, scientists estimated that the number of species was around 16,000no one had ever counted them all up, though. In a new paper in Scientific Reports, the same scientists delved into museum collections from around the world to confirm just how many tree species have been recorded in the Amazon so farand how many have yet to be discovered.

One of earth's most-loved species is at risk from climate change

2016-07-06 20:24:00| Climate Ark Climate Change & Global Warming Newsfeed

Market Watch: Adélie Penguins, the small, flightless birds found along the Antartic coast, are gradually losing their home to climate change, according to a new report. About a third of current Adélie penguin colonies, which is about 20% of their overall population, may be in decline by 2060, according to a study published in Scientific Reports, part of the Nature journal. The direct or indirect effects of this warming are detrimental to Adélie penguin populations and could lead to population declines at...

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,...
