Are jellyfish increasing in world's oceans?ScienceDaily.com | 01 Feb 2012A global study has questioned claims that jellyfish are increasing worldwide. Blooms, or proliferation, of jellyfish have shown a substantial, visible impact on coastal populations -- clogged nets for fishermen, stinging waters for tourists, even choked intake lines for power plants -- and recent...
Biodiversity | Global Warming First plants caused ice ages, new research revealsScienceDaily.com | 01 Feb 2012New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages. The research reveals the effects that the first land plants had on the climate during the Ordovician Period, which ended 444 million years ago. During this period the climate gradually cooled, leading to a series of 'ice ages.' This global cooling was caused by a dramatic reduction in atmospheric carbon, which this research now suggests was triggered by the arrival of plants.
Biodiversity | Extreme Weather | Research What really happened prior to 'Snowball Earth'?ScienceDaily.com | 27 Jan 2012The large changes in the carbon isotopic composition of carbonates which occurred prior to the major climatic event more than 500 million years ago, known as "Snowball Earth," are unrelated to worldwide glacial events, a new study suggests.
Biodiversity | Research Carbon dioxide is 'driving fish crazy'ScienceDaily.com | 20 Jan 2012Rising human carbon dioxide emissions may be affecting the brains and central nervous system of sea fishes with serious consequences for their survival, an international scientific team has found. Carbon dioxide concentrations predicted to occur in the ocean by the end of this century will interfere with fishes' ability to hear, smell, turn and evade predators, says a professor.
