Clownfish became a household name over a decade ago when Disney released the movie “Finding Nemo.” The colorful fish are now at risk due to bleaching of their sea anemone homes in the Indo-Pacific, which has increased due to rising ocean temperatures. University of Delaware researcher Danielle Dixson has co-authored a paper demonstrating how vulnerable clownfish are to the increased frequency of bleaching events.
A symbiotic relationship that has existed since the time of the dinosaurs is at risk of ending, as habitat loss and environmental change mean that a species of Australian crayfish and the tiny worms that depend on them are both at serious risk of extinction.
Study shows that sea urchins defy aging, regardless of lifespan.
The researchers examined data from research and monitoring reports from the years 2000-2012, to see what chemicals have been analysed in Baltic Sea fish.
Coral reefs – stunning, critical habitats for an enormous array of prized fish and other species – have survived five major extinction events over the last 250 million years. Now, an international team of scientists led by Rutgers faculty has conducted the world’s most comprehensive analysis of coral genes, focusing on how their evolution has allowed corals to interact with and adapt to the environment. A second study led by Rutgers researchers with colleagues at the University of Hawaii shows – for the first time – how stony corals create their hard skeletons, using proteins as key ingredients.
Light doesn’t travel very far underwater so the navy uses sound to transmit messages. The speed of underwater sound depends on a combination of temperature, salinity and pressure. Understanding sound speed is crucial for transmitting messages, detecting enemy submarines and avoiding marine animals. As climate change elevates temperatures, understanding underwater sound speed will become increasingly important.
A dolphin chasing a tasty fish will produce a stream of rapid-fire echolocation clicks that help it track the speed, direction and distance to its prey. Now researchers have developed a model that could yield new insights into how the charismatic marine mammals make these clicks – and it turns out snot may play an important role. The researchers will present their model at the 171st meeting of the Acoustical Society of America.
For the first time, two mathematicians at Canada’s University of Waterloo have created a 3-D simulation of the mass transport capabilities of mode-2 waves. Such models will help define how mode-2 waves can carry materials that are either beneficial (such as phytoplankton and other food sources) or detrimental (such as crude oil and other contaminants) between ecosystems. The simulation is described this week in Physics of Fluids.
Jumping up a 2-foot waterfall is an impossible task for small fish like minnows and shiners. Such an obstacle can inhibit their ability to feed and spawn upstream. But state and federal wildlife agencies may soon be able to install fish ladders on the downside side of culverts to prevent this from happening.
New Species of Marine Life Named One of the Year's Best Discoveries
University of Adelaide environmental researchers have called for a ‘code of best practice’ in using unmanned aerial vehicles (drones) for wildlife monitoring and protection, and other biological field research.
Unlike the declining populations of many fish species, the number of cephalopods (octopus, cuttlefish and squid) has increased in the world’s oceans over the past 60 years, a University of Adelaide study has found.
In a new study, University of Washington researchers found that selectively fishing for lingcod in protected areas actually avoided hampering the recovery of other fish, including rockfish species listed as overfished.
Fifty-nine finfish species have ‘disappeared’ from fishermen’s catches in the world’s most species rich and vulnerable marine region, new research has shown.
Researchers investigating the commonalities in pitch delivery by presidential candidates, the biological basis for dolphin echolocation, and an early warning system to detect tsunamis will describe their latest findings during a webcast press event on Tuesday, May 24, 2016. The event will be streamed live at 1:00 p.m., EDT, from the 171st meeting of the Acoustical Society of America (ASA), which takes place May 23-27 in Salt Lake City. Additionally, the webcast will be available for download 24 hours afterwards.
Conventional wisdom says removing beach debris helps sea turtles nest; now, as sea-turtle nesting season gets underway, a new University of Florida study proves it.

In the study, clearing the beach of flotsam and jetsam increased the number of nests by as much as 200 percent, while leaving the detritus decreased the number by nearly 50 percent.
SAR11, the most abundant plankton in the world's oceans, are pumping out massive amounts of two sulfur gases that play important roles in the Earth's atmosphere, researchers announced today in the journal Nature Microbiology.
As climatologists closely monitor the impact of human activity on the world’s oceans, researchers at the Georgia Institute of Technology have found yet another worrying trend impacting the health of the Pacific Ocean.

The Ocean Observatories Initiative's data center, which collects and shares data from more than 800 instruments and a transmission network across the Atlantic and Pacific, is operating at Rutgers. The university has an initial $11.8 million contract to design, build and operate the OOI cyberinfrastructure.
Researchers call for socioeconomic infuences to be factored into future protection policies.
The University of Chicago, the Marine Biological Laboratory (MBL), and the U.S. Department of Energy's Argonne National Laboratory announced today a new partnership called The Microbiome Center that will combine the three institutions' efforts to understand the identity and function of microbes across environments.

Scientists from the Charles Darwin Research Station (CDRS) and the National Geographic Society revealed that the northern Galápagos islands of Darwin and Wolf are home to the largest shark biomass reported to date (12.4 tons per hectare).
Using phylogenetic software to analyze algae from ocean depths of more than 100 meters, UA biologist Dr. Juan Lopez-Bautista discovered multi-cellular structures that diversified more than 540 millions years ago
Whether fish hunt nearshore or in the open water and what prey they eat affect the amount of mercury that accumulates in them, a Dartmouth College study shows.
Dust from the Saharan desert is bringing needed iron and other nutrients to underwater plants in the Caribbean, but bacteria may be the first thing to prosper from that dust. The dust is causing the bacteria to bloom and also become more toxic to humans and marine organisms.
Earth system scientists from the University of California, Irvine have taken water samples from the north Pacific, north and south Atlantic, and Arctic oceans in search of repositories of black carbon, soot from burning biomass and diesel engines, among other sources. They’ve found considerably less of the material than expected, and they’ve discovered that it exists in at least two varieties, a younger pool closer to the ocean’s surface that is absorbed into the environment in a roughly 100-year cycle and an ancient reserve that remains stable for millennia.
For the first time ever, an international research team under his direction studied the geographical pattern by which new species of corals and reef fish evolved over the millions of years of evolutionary history using a computer model.

In a new study, University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers found that the limestone that forms the foundation of coral reefs along the Florida Reef Tract is dissolving during the fall and winter months on many reefs in the Florida Keys. The research showed that the upper Florida Keys were the most impacted by the annual loss of reef.
When it comes to reducing the number of walleye, anglers take a back seat to Mother Nature. That’s the one of the insights on harvest dynamics emerging from a research project to assess movement, mortality and the impact of anglers on walleye populations along the Missouri River from the Oahe Dam near Pierre, South Dakota, north to the Garrison Dam near Riverdale, North Dakota.
