PNAS Article reports new evidence that microbial algae in Caribbean came from the Pacific likely via the Panama Canal. Algae offers short term benefits to coral communities but could do long-term damage.
Are males truly essential for reproduction? Female birds, reptiles and sharks living in captivity have sometimes surprised their keepers by giving birth even though, as far as anyone can remember, they have never been housed with a male. Scientists used DNA analysis to solve this mystery some time ago, showing that these offspring were produced by asexual reproduction, a process called parthenogenesis, or “virgin birth.” Although these events have captured tremendous public interest, it was unknown if this ever occurred in wild populations of these animals.
Just as with plants on land, a common species of ocean diatom grows faster in the presence of helpful bacteria.
A new study, by scientists from the University of Southampton and National Oceanography Centre (NOC), implies that the global climate is on the verge of broad-scale change that could last for a number of decades.

A factor that determines the properties of clouds that help moderate the planet’s temperature may be decided in the oceans.
After nearly a year of transmitting incredible data, tagged mako shark has been caught
The same theory that explains individual differences in human speech has recently been applied to other members of the animal kingdom, including dogs and deer. Now researchers from Syracuse University in New York are working to understand whether individually distinctive vocal characteristics of North Atlantic right whales could be used to identify and track individuals -- a potentially useful tool for studying an endangered species that spends much of its life hidden under the water.
A chemical signature recorded on the ear bones of Chinook salmon from Alaska’s Bristol Bay region could tell scientists and resource managers where they are born and how they spend their first year of life.

The Fishery Performance Indicators are the most comprehensive, global tool that considers social factors in addition to the usual biological measures when gauging a fishery's health. The new tool is described in a paper published May 6 in PLOS ONE.
The Global Biological Standards Institute (GBSI) has launched a video competition as part of its #authenticate campaign, which is designed to raise awareness in the life science community about the powerful role cell authentication can play in improving research reproducibility and fidelity.
They may not be on Facebook or Twitter, but dolphins do, in fact, form highly complex and dynamic networks of friends, according to a recent study by scientists at Harbor Branch Oceanographic Institute at Florida Atlantic University. Dolphins are known for being highly social animals, and a team of researchers at HBOI took a closer look at the interactions between bottlenose dolphins in the Indian River Lagoon (IRL) and discovered how they mingle and with whom they spend their time.
Researchers at the University of Washington’s Friday Harbor Laboratories are looking at how the biomechanics of clingfish could be helpful in designing devices and instruments to be used in surgery and even to tag and track whales in the ocean.
A team of researchers from the University of California, Davis, the Wildlife Conservation Society, and other groups has focused its attention on fishery improvement projects (FIPs), which are designed to bring seafood from wild fisheries to the certified market, with only a promise of sustainability in the future. They conclude that FIPs need to be fine-tuned to ensure that fisheries are delivering on their promises.
It has been five years since the Deepwater Horizon explosion. Are Gulf states better prepared today to deal with the next disaster?
Following the Deepwater Horizon Oil Spill in 2010, many people were concerned that seafood was contaminated by either the oil or dispersants used to keep the oil from washing ashore. Ina University of Florida study, all seafood tested so far has shown “remarkably low contaminant levels,” based on FDA standards, and revealed that: • 74 percent of samples were below quantifiable limits; • 23 percent of samples were between 0.1-0.9 parts per billion, and; • 3 percent of samples were between 1.0 and 48 parts per billion.
Researchers from FAU's Harbor Branch Oceanographic Institute have published findings on the impacts of the Deepwater Horizon oil spill on marine organisms such as oysters, conch, shrimp, corals as well as marine plankton (microalgae or phytoplankton, rotifers or zooplankton), which provide the basis of coastal and oceanic food webs.
The dispersant used to remediate the 2010 Deepwater Horizon oil spill in the Gulf of Mexico is more toxic to cold-water corals at lower concentrations than the spilled oil, according to a new study that comes on the eve of the spill’s fifth anniversary, April 20th.
Fish are the key ingredients in a new recipe to diagnose and restore degraded coral reef ecosystems, according to scientists from the Australian Institute of Marine Science, WCS, James Cook University, and other organizations in a new study in the journal Nature.
A new study shows for the first time that fishing likely worsens population collapses in species of forage fish, including herring, anchovies and sardines. Some of the largest fisheries in the world target these species, and these "baitfish" are also a key source of food for larger marine animals, including salmon, tuna, seabirds and whales.
A team of engineers and biologists reports new progress in using computer modeling and 3D shape analysis to understand how the unique grasping tails of seahorses evolved. These prehensile tails combine the seemingly contradictory characteristics of flexibility and rigidity, and knowing how seahorses accomplish this feat could help engineers create devices that are both flexible and strong.
