Study Says Amazon Biodiversity Faces New Adversary: Hydroelectric Dams : SCIENCE : Tech Times

… Anglia conducted the study by assessing the patterns at which medium and large populations of arboreal and terrestrial vertebrates—35 species of birds, tortoises and mammals—would react to an environment that had undergone 26 years of archipelagic changes. Such modifications include changes in habitat quality and landscape formation in a large hydroelectric facility located in the Central Amazonia. The facility where they conducted their biodiversity surveys is called the Balbina Dam, which …

News – Study: Rabbits may have driven Neanderthals to extinction – The Weather Network

… There’s a chance you drank dinosaur urine. Here’s why. “If Neanderthals were more tied to these large mammals, the loss of them could have driven them to extinction.” Dr. Stewart’s team suggests that modern humans were able to adapt to their changing surroundings and employed the uses of traps to help them catch smaller and faster prey, like rabbits. The ability to adapt to an evolving landscape has researchers interested because it mimics humanity’s current …

Global warming leads to hybrids driving species loss

By Jayalakshmi K | June 2, 2015 Organisms are liberally exchanging genes with other species to create hybrid species, thanks to global warming. In the process, many species are dying out. Interbreeding is a natural process and even modern humans are the product of such genetic exchange with the Neanderthals. But climate change is accelerating the trend by changing the landscape, warn researchers. The changing habitats are bringing together species that never interbred before. Grizzly bears and …

World at risk of ’empty landscape’ as biggest herbivores face extinction

By Hannah Osborne | May 1, 2015 The planet is at risk of becoming an “empty landscape”, with the world’s biggest herbivore populations rapidly declining. Researchers looked at 74 species of the world’s biggest herbivores (weighing over 100kg) and analysed data such as endangerment status, key threats and ecological consequences of population declines. Findings paint a bleak picture, with Africa and parts of Asia particularly at risk of becoming barren of these species, …
