Sticklebacks infected with parasites influence behavior of healthy fish
Certain types of tapeworm make sticklebacks behave carelessly and thus become easier prey for birds. A team of biologists have now demonstrated for the first time that the tapeworm not only influences the behavior of the infected fish -- indirectly, it can also induce risky behavior in other fish in the group.

Fish's use of electricity might shed light on human illnesses
African weakly electric fish, commonly called baby whales, use incredibly brief electrical pulses to sense the world around them and communicate with other members of their species. Part of that electrical mechanism exists in humans -- and by studying these fish, scientists may unlock clues about conditions like epilepsy.

Beluga whales have sensitive hearing, little age-related loss
Scientists published the first hearing tests on a wild population of healthy marine mammals. The tests on beluga whales in Bristol Bay, Alaska, revealed that the whales have sensitive hearing abilities and the number of animals that experienced extensive hearing losses was far less than what scientists had anticipated.

Boring barnacles prefer the shallow life on coral reefs
Scientists have quantified how barnacles infest stony coral over a variety of conditions and reduce calcium carbonate on reefs. Coral reefs harbor diverse marine life and help prevent coastal erosion.

When cozying up with would-be predators, cleaner shrimp follow a dependable script
It's a mystery how cleaner shrimp partner with would-be fish predators -- sometimes even climbing in their mouths -- without getting eaten. A new study reveals how the shrimp convinces fish not to eat them, and the fish conveys that it's a friend and not a foe.

Deep-sea marine sponges may hold key to antibiotic drug resistance
FAU's Harbor Branch houses more than 1,000 strains of actinobacteria, one of the most prolific microbial groups for the production of natural products. Derived from sea sponges and other macro-organisms, several strains were identified for their potent antifungal activity, for anti-MRSA activity, and for both antifungal and antibacterial activities. A key finding was the identification of a strain that produced metabolites that are more potent than the bacterial antibiotic, vancomycin, against C. difficile.

Local interventions boost coral's resilience to bleaching
Local conservation actions can significantly boost coral's resilience to, and recovery from, climate-induced thermal bleaching by reducing other energy-sapping stresses the coral faces, a new study finds. Scientists found they could reduce the extent of bleaching by half if they removed or reduced populations of coral-eating snails from affected reefs. The coral's recovery from bleaching was also enhanced.

Rising sea temperatures threaten survival of juvenile albatross
Changes in sea surface temperature affect the survival of albatross during their first year at sea, resulting in a reduced population growth rate when temperatures are warmer than the current average, a new study has revealed.
