Finding the 'conservación' in conservation genetics
A recently published special issue of the Journal of Heredity focuses on case studies of real-world applications of conservation genetics in Latin America, from nabbing parrot smugglers to exposing fraudulent fish sales.

Sardines, anchovies, other fast-growing fish vulnerable to dramatic population plunges
A Rutgers marine biologist studying the rise and fall of fish populations worldwide recently made a counterintuitive discovery: ocean species that grow quickly and reproduce frequently are more likely to experience dramatic plunges in population than larger, slower growing fish such as sharks or tuna. In nearly all of the cases, overfishing was the culprit. Combining climate variability with high levels of fishing greatly increases the risk of population collapse.

Seagrass thrives surprisingly well in toxic sediments -- but still dies all over the world
Toxic is bad. Or is it? New studies of seagrasses reveal that they are surprisingly good at detoxifying themselves when growing in toxic seabed. But if seagrasses are stressed by their environment, they lose the ability and die. All over the world seagrasses are increasingly stressed and one factor contributing to this can be lack of detoxification.

Fish that have their own fish finders
African fish called mormyrids communicate by means of electric signals. Fish in one group can glean detailed information from a signal's waveform, but fish in another group are insensitive to waveform variations. Research at Washington University in St. Louis has uncovered the neurological basis for this difference in perception.

Low levels of endocrine disruptors in the environment may cause sex reversal in female frogs
Many studies have been conducted on the dangers of endocrine disrupting chemicals that mimic or block estrogen, the primary female hormone. Now new research shows that similar harm can be done by chemicals that affect male hormones, or androgens.

Greenhouse gases' millennia-long ocean legacy
Continuing current carbon dioxide emission trends throughout this century and beyond would leave a legacy of heat and acidity in the deep ocean. These changes would linger even if the atmospheric carbon dioxide concentration were to be restored to pre-industrial levels at some point in the future, according to a new paper. This is due to the tremendous inertia of the ocean system.

Ocean changes are affecting salmon biodiversity and survival
What happens at the Equator, doesn't stay at the Equator. El Niño-associated changes in the ocean may be putting the biodiversity of two Northern Pacific salmon species at risk, according to a UC Davis study.

CO2 removal cannot save the oceans -- if we pursue business as usual
Greenhouse-gas emissions from human activities do not only cause rapid warming of the seas, but also ocean acidification at an unprecedented rate. Artificial carbon dioxide removal (CDR) from the atmosphere has been proposed to reduce both risks to marine life. A new study based on computer calculations now shows that this strategy would not work if applied too late. CDR cannot compensate for soaring business-as-usual emissions throughout the century and beyond.

Study offers new insights on hurricane intensity, pollution transport
As tropical storm Isaac was gaining momentum toward the Mississippi River in August 2012, University of Miami researchers were dropping instruments from the sky above to study the ocean conditions beneath the storm. The newly published study showed how a downwelling of warm waters deepened the storm's fuel tank for a rapid intensification toward hurricane status. The results also revealed how hurricane-generated currents and ocean eddies can transport oil and other pollutants to coastal regions.

Studying killer whales with an unmanned aerial vehicle
Last year, for the first time, scientists used an unmanned aerial vehicle to photograph killer whales from above, giving scientists a new way to monitor killer whale health while giving us all a stunning new view of the species. In a recent article in the Journal of Unmanned Vehicle Systems, scientists explain how they configured the UAV into a precision scientific instrument.

Treating ships' ballast water: Filtration preferable to disinfection
Untreated ballast water discharge from ships can spread living organisms and even pathogens across the world thereby introducing non-native or invasive species into the local environment. Scientists at Helmholtz Zentrum München therefore recommend using physical treatment processes such as filtration rather than electrochemical disinfection, which creates countless potentially toxic compounds. These are the findings of a recent study published in the journal Environmental Science and Technology.

Scientists urge ban on salamander imports to fend off deadly fungus
California amphibian experts warn that a recently discovered fungus already devastating salamanders in Europe could imperil American salamanders, and urge the US Fish and Wildlife Service to immediately halt salamander imports until there is a plan to detect and prevent spread of the fungus. SF State University, UC Berkeley and UCLA biologists say the fungus, dubbed Bsal, is worse than the Bd chytrid fungus that has brought more than 200 amphibian species worldwide near extinction.

New study exposes negative effects of climate change on Antarctic fish
Scientists at University of California Davis and San Francisco State University have discovered that the combination of elevated levels of carbon dioxide and an increase in ocean water temperature has a significant impact on survival and development of the Antarctic dragonfish (Gymnodraco acuticeps). The research article was published today in the journal Conservation Physiology.

Boxfish shell inspires new materials for body armor and flexible electronics
The boxfish's unique armor draws its strength from hexagon-shaped scales and the connections between them, engineers at the University of California, San Diego, have found. They describe their findings and the carapace of the boxfish (Lactoria cornuta) in the July 27 issue of the journal Acta Materialia. Engineers also describe how the structure of the boxfish could serve as inspiration for body armor, robots and even flexible electronics.
