Exposure to water that is both salty and fresh is key to future success

Wed, 17 Jan 2018 13:54:20 EST ~ According to Charles Darwin the ability to adapt to new conditions is essential for survival of species. The capacity to cope with altered conditions is becoming increasingly important in the face of climate change. New evidence on salt water tolerance in spawning migrating pike from the Baltic Sea suggests that not being adapted to specific local environments may promote persistence in an uncertain, rapidly changing world.

Scale-eating fish adopt clever parasitic methods to survive

Wed, 17 Jan 2018 13:51:36 EST ~ A small group of fishes -- possibly the world's cleverest carnivorous grazers -- feeds on the scales of other fish in the tropics. Biologists are trying to understand these scale-feeding fish and how this odd diet influences their body evolution and behavior. Find out more...

Coping with climate stress in Antarctica

Wed, 17 Jan 2018 12:16:40 EST ~ Some Antarctic fish living in the planet's coldest waters are able to cope with the stress of rising carbon dioxide levels the ocean. They can even tolerate slightly warmer waters. But they can't deal with both climate change stressors at the same time, according to a new study. Find out more...

California sea lion population rebounded to new highs

Wed, 17 Jan 2018 11:50:03 EST ~ California sea lions have fully rebounded under the protection of the Marine Mammal Protection Act, with their population on the West Coast reaching carrying capacity in 2008 before unusually warm ocean conditions reduced their numbers, according to the first comprehensive population assessment of the species.

Nanowrinkles could save billions in shipping and aquaculture

Wed, 17 Jan 2018 09:23:42 EST ~ Biofouling costs shipping billions in increased fuel costs and affects aquaculture. A nanostructured surface inspired by the carnivorous pitcher plant could slash those costs. Find out more...

No-fishing zones help endangered penguins

Drones confirm importance of Costa Rican waters for sea turtles

Tue, 16 Jan 2018 15:12:59 EST ~ A new drone-enabled population survey -- the first ever on sea turtles -- shows that larger-than-anticipated numbers of turtles aggregate in waters off Costa Rica's Ostional National Wildlife Refuge. Scientists estimate turtle densities may reach up to 2,086 animals per square kilometer. The study underscores the importance of the Ostional habitat; it also confirms that drones are a reliable tool for surveying sea turtle abundance. Find out more...

Surfers three times more likely to have antibiotic-resistant bacteria in guts

Mon, 15 Jan 2018 09:42:43 EST ~ Scientists compared fecal samples from surfers and non-surfers to assess whether the surfers' guts contained E. coli bacteria that were able to grow in the presence of the antibiotic cefotaxime. Cefotaxime has previously been prescribed to kill off these bacteria, but some have acquired genes that enable them to survive this treatment. The study found that 13 of 143 (9 percent) of surfers were colonized by these resistant bacteria, compared to just four of 130 (3 percent) of non-surfers swabbed. Find out more...

Robots aid better understanding of phytoplankton blooms

Mon, 15 Jan 2018 09:42:31 EST ~ Phytoplankton blooms are one of the most important factors contributing to the efficiency of the carbon pump in the North Atlantic Ocean. To better understand this phenomenon, researchers have developed a new class of robots able to collect data in the ocean throughout the year. Using these unparalleled data, the researchers have identified the starting point for the explosive spring phytoplankton bloom. Find out more...

New application for acoustics helps estimate marine life populations

Mon, 15 Jan 2018 09:42:25 EST ~ Researchers have for the first time have used hydroacoustics as a method for comparing the abundance of fishes within and outside marine protected areas (MPAs). Find out more...
