Peru's Manu National Park sets new biodiversity record
When it comes to amphibian and reptile biodiversity, the eastern slopes of the Andes mountains in South America stand out. A new survey of 'herps' in and around Manu National Park in Peru by UC Berkeley postdoc Rudolf von May and his Illinois colleagues Alessandro Catenazzi and Edgar Lehr recorded a greater biodiversity -- 287 species, some new to science -- than any other protected area in the world, including the previous leader in Ecuador.

Surveys find that despite economic challenges Malagasy fishers support fishing regulations
Scientists from the Wildlife Conservation Society, the ARC Centre of Excellence for Coral Reef Studies, and other groups have found that the fishing villages of Madagascar -- a country with little history of natural resource regulation -- are generally supportive of fishing regulations, an encouraging finding that bodes well for sustainable strategies needed to reduce poverty in the island nation.

Stratification determines the fate of fish stocks in the Baltic Sea
In the Baltic Sea, two cod stocks evolve independently. Also, the juveniles of two economically important flatfish species, flounder and plaice, live there within limited space. This is possible due to the different salinity within this inland sea. Scientists of GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany and the National Institute of Aquatic Resources, Denmark, explain how these hydrographic conditions affect the distribution of fish eggs and growth of economically important fish stocks.

The ups and downs of early atmospheric oxygen
The period of extended low oxygen spanning from roughly two to less than one billion years ago was a time of remarkable chemical stability in the Earth's ocean and atmosphere. A University of California, Riverside team of biogeochemists reports that oxygen was much lower than previously thought during this important middle chapter in Earth history, which likely explains the low abundances and diversity of eukaryotic organisms and the absence of animals.

Pond-dwelling powerhouse's genome points to its biofuel potential
Duckweed is a tiny floating plant that's been known to drive people daffy. It's one of the smallest and fastest-growing flowering plants that often becomes a hard-to-control weed in ponds and small lakes. But it's also been exploited to clean contaminated water and as a source to produce pharmaceuticals. Now, the genome of Greater Duckweed (Spirodela polyrhiza) has given this miniscule plant's potential as a biofuel source a big boost.

Research of zebrafish neurons may lead to understanding of birth defects like spina bifida
Using zebrafish, scientists can determine how individual neurons develop, mature and support basic functions like breathing, swallowing and jaw movement. Researchers at the University of Missouri say that learning about neuronal development and maturation in zebrafish could lead to a better understanding of birth defects such as spina bifida in humans.

A battery small enough to be injected, energetic enough to track salmon
Scientists have created a microbattery that packs twice the energy compared to current microbatteries used to monitor the movements of salmon. The battery is just slightly larger than a long grain of rice and can be injected into an organism.

Dartmouth-UConn study shows coastal water, not sediment, predicts mercury contamination
A Dartmouth-University of Connecticut study of the northeast United States shows that methylmercury concentrations in estuary waters -- not in sediment as commonly thought -- are the best way to predict mercury contamination in the marine food chain.

Ancient herring catch nets fisheries weakness
Archaeological data indicate modern herring management needs to take a longer look into the past to manage fisheries for the future says a new study involving Simon Fraser University researchers. That is one of the key findings in the study, just published online in Proceedings of the National Academy of Sciences. SFU researchers Iain McKechnie, Dana Lepofsky and Ken Lertzman, and scientists in Ontario, Alberta and the United States are its co-authors.

Do Guam mantas plan moon parties?
Guam mantas will be forever mentioned in the scientific literature because of UOG Master of Biology candidate Julie Hartup's passion for her research subject. She has been studying Guam's Manta alfredi for eight years and is the first to document a very interesting behavior, mantas eating fish spawn.

Scientists call for new stewardship of the deep ocean: Earth's last frontier
Humans are encroaching more vigorously into the ocean's deep regions, exploiting its resources and putting its habitats and natural services at risk. Lisa Levin of Scripps Institution of Oceanography at UC San Diego believes a new "stewardship mentality" across disciplines is required for the future health and integrity of the deep ocean. Levin and several other experts will describe this need Feb. 16 during a news briefing and symposium at the AAAS meeting in Chicago.

Deep ocean needs policy, stewardship where it never existed
Plans to begin mining nodules of valuable metals from deep ocean deposits have oceanographers concerned about the lack of public awareness or international agreements governing these habitats. "The deep sea is out of sight, out of mind ... there's a whole level of concern that isn't being expressed when it comes to deep sea industrialization," said Cindy Van Dover of the Duke Marine Lab.

Arctic biodiversity under serious threat from climate change according to new report
Climate change caused by human activities is by far the worst threat to biodiversity in the Arctic. Some of these changes are already visible. Unique and irreplaceable Arctic wildlife and landscapes are crucially at risk due to global warming caused by human activities according to the Arctic Biodiversity Assessment, a new report prepared by 253 scientists from 15 countries under the auspices of the Arctic Council.

Scientists discover the mechanism of heart failure in fish exposed to oil spills
Researchers from NOAA Fisheries and Stanford University, working on the Natural Resources Damage Assessment following the Deepwater Horizon Oil Spill, have found that some petroleum compounds act as ion channel blockers in the heart cells of young tuna, disrupting normal cardiac function. This will lead to the creation of new diagnostic tools for measuring the biological impact of pollution, and may have implications for the health of vertebrates other than fish as well.

Valentine's Day: True love makes pacific salmon healthier
Salmon can spot their true love across a crowded stream, according to research from a university-industry partnership involving the University of Waterloo. Allowing female salmon to follow their heart and mate with the male of their choice produces healthier babies than those who have their mates selected for them.

Stanford, NOAA scientists discover mechanism of crude oil heart toxicity
While studying the impact of the 2010 Deepwater Horizon oil spill on tuna, a research team led by Barbara Block, a professor of marine sciences, discovered that crude oil interrupts a molecular pathway that allows fish heart cells to beat effectively. The components of the pathway are present in the hearts of most animals, including humans.
