Scientists lack vital knowledge on rapid Arctic climate change

Wed, 18 Jul 2018 12:24:36 EDT ~ Arctic climate change research relies on field measurements and samples that are too scarce, and patchy at best, according to a comprehensive review study. The researchers looked at thousands of scientific studies, and found that around 30% of cited studies were clustered around only two research stations in the vast Arctic region. Find out more...

Potential for Antarctica to become plastics dumping ground and home for new species

Wed, 18 Jul 2018 09:24:57 EDT ~ Antarctica is not as isolated from the rest of the world as scientists have thought, new research reveals, with potential for drifting plastics to create problems in the continent in future and new species to colonise there as the climate warms. Find out more...

5,000 percent increase in native trees on rat-free palmyra atoll

Tue, 17 Jul 2018 14:25:35 EDT ~ New research demonstrates dramatic positive benefits for native trees following rat removal at Palmyra Atoll, a magnificent National Wildlife Refuge and natural research laboratory located about 1000 miles south of Hawaii. For five native tree species, including Pisonia grandis, fewer than 150 seedlings were counted in the presence of rats, and more than 7700 seedlings were counted five years after rats were removed.

Protecting tropical forest carbon stocks may not prevent large-scale species loss

Mon, 16 Jul 2018 16:45:20 EDT ~ As the world seeks to curb human-induced climate change, will protecting the carbon of tropical forests also ensure the survival of their species? A study suggests the answer to this question is far from straightforward. Forests with the greatest carbon content do not necessarily house the most species, meaning carbon-focused conservation can miss large swathes of tropical forest biodiversity. Find out more...

Indigenous peoples own or manage at least one quarter of world's land surface

Mon, 16 Jul 2018 13:07:32 EDT ~ Indigenous Peoples have ownership, use and management rights over at least a quarter of the world's land surface according to a new study. Find out more...

Mangroves to mudflats and not back again

Mon, 16 Jul 2018 11:46:13 EDT ~ The long-term conversion of mangroves to mudflats can lead to destabilization of shorelines, negatively impacting their resilience to extreme weather events. Find out more...

Better methods improve measurements of recreational water quality

Fri, 13 Jul 2018 13:51:14 EDT ~ The concentration of enterococci, bacteria that thrive in feces, has long been the federal standard for determining water quality. Researchers have now shown that the greatest influences on that concentration are the quantity of mammalian feces in the water, and the numbers of enterococci that glom onto floating particulate matter.

Growth rates of loblolly pine trees

Thu, 12 Jul 2018 14:16:22 EDT ~ Researchers used ecological forecasting to predict how changes in temperature, water, and concentrations of carbon in the atmosphere in the Southeastern United States may affect the future growth rates of trees. Find out more...

Climate change-induced march of treelines halted by unsuitable soils

Thu, 12 Jul 2018 13:24:20 EDT ~ Researchers have discovered unsuitable soil at higher altitudes may be halting the advancement of treelines. This finding dispels the commonly held assumption that climate change is enabling trees to move farther uphill and northward. The researchers looked at plant growth at higher altitudes in the Canadian Rockies, grew spruce and fir seedlings at varying elevations and collected soil samples from the same areas to grow spruce seeds in growth chambers .

Geological records reveal sea-level rise threatens UK salt marshes, study says

Thu, 12 Jul 2018 10:05:35 EDT ~ Sea-level rise will endanger valuable salt marshes across the United Kingdom by 2100 if greenhouse gas emissions continue unabated, according to an international study. Moreover, salt marshes in southern and eastern England face a high risk of loss by 2040, according to the study. Find out more...
