Fish moving poleward at rate of 26 kilometres per decade

Fish moving poleward at rate of 26 kilometres per decade | Nature enviroment and life. | Scoop.it
Large numbers of fish will disappear from the tropics by 2050, finds a new study that examined the impact of climate change on fish stocks. The study identified ocean hotspots for local fish extinction but also found that changing temperatures will drive more fish into the Arctic and Antarctic waters.

Evolution in rainforest flies points to climate change survival

Evolution in rainforest flies points to climate change survival | Nature enviroment and life. | Scoop.it
Scientists believe some tropical species may be able to evolve and adapt to the effects of climate change. The new findings suggests some sensitive rainforest-restricted species may survive climate change and avoid extinction. But only if the change is not too abrupt and dramatically beyond the conditions that a species currently experiences.

Climate change and the ecology of fear

Climate change and the ecology of fear | Nature enviroment and life. | Scoop.it
Climate change is predicted to have major impacts on the many species that call our rocky shorelines home. Indeed, species living in these intertidal habitats, which spend half their day exposed to air and the other half submerged by water, may be subjected to a double whammy as both air and water temperatures rise. Given the reliance of human society on nearshore coastal ecosystems, it is critical that we better understand how climate change will affect them.

The same climatic drivers that enhance upwelling of nutrient-rich ocean waters and support of marine productivity can result in lower precipitation on land and slower tree-growth. Tree-ring chronologies helped to explain how upwelling was happening during the past 600 years.
