South Africa: Low Levels of Genetic Diversity Are Putting Great White Sharks At Risk

… creatures. Research on the DNA of white sharks around the South African coastline shows that the population has extremely low geneticdiversity. This finding holds serious implications for their survival and more analysis is being done to try and understand this unexpected outcome and predict its consequences for the future of the species. What genetic diversity tells us Genetic diversity is an important indicator of the health status of a population in the wild: the higher the diversity, the …

Why eco-socialism is the only option | Green Left Weekly

… earth’s surface, atmosphere and water. Already, climate change is creating absolute disaster for much of the world.

Earth’s sixth great extinction has begun, a new analysis finds | MinnPost

… might have taken between 800 and 1,000 years at the background extinction rate. Their conclusions about the consequences of these losses, attributed almost entirely to human overconsumption of planetary resources, are anything but reassuring: If the currently elevated extinction pace is allowed to continue, humans will soon (in as little as three human lifetimes) be deprived of many biodiversity benefits. On human time scales, this loss would be effectively permanent because in the aftermath of …

Critically endangered species should be left to breed in the wild

… “Programmes can fail for many reasons, including delays in achieving successful breeding, failure to build up a self-sustaining population, domestication and loss of genetic diversity, and poor performance after releases into the wild. “Captive breeding can reduce motivation and resources for conservation in the wild, with disastrous consequences.
