Climate change affecting fish in Ontario lakes
Researchers have found warmer average water temperatures in Ontario lakes over the past decade have forced fish to forage in deeper water.

Half-a-billion-year-old fossil reveals the origins of comb jellies
One of the ocean's little known carnivores has been allocated a new place in the evolutionary tree of life after scientists discovered its unmistakable resemblance with other sea-floor dwelling creatures.

Coral reefs near equator less affected by ocean warming
Ocean warming is threatening coral reefs globally, with persistent thermal stress events degrading coral reefs worldwide, but a new study has found that corals at or near the equator are affected less than corals elsewhere.

Eating fish may help prevent asthma
An innovative study has revealed new evidence that eating fish can help prevent asthma.

Tracking turtles with telemetry
A new model has been created that can forecast the location of Eastern Pacific leatherback turtles along the coast of Central and South America in an effort to decrease bycatch mortality of this critically endangered and ecologically important species.

Researchers uncover new clues to surviving extinction
'Great Dying' extinction survivors appear to have shared many of the same ecological roles as their predecessors, with one catch -- there was a surge in the number of individuals with more modern traits. These hardy stand-outs did a better job of driving recovery, making ongoing ecological interactions more intense. Insights into this ancient marine system and its occupants can help guide modern conservation in identifying Earth's most resilient species in the face of environmental stress.

Sea otters' tool use leaves behind distinctive archaeological evidence
Researchers have analyzed the use by sea otters of large, shoreline rocks as 'anvils' to break open shells, as well as the resulting shell middens. The researchers used ecological and archaeological approaches to identify patterns that are characteristic of sea otter use of such locations. By looking at evidence of past anvil stone use, scientists could better understand sea otter habitat use.

Role of sea urchins on California kelp
California sheephead and spiny lobsters may be helping control sea urchin populations in Southern California kelp forests, where sea otters -- a top urchin predator -- have long been missing, according to a new study. The research provides new insight into the complex predator-prey relationships in kelp forests that can be seen in the absence of sea otters.

Scientists crack genome of superfood seaweed, ito-mozuku
For the first time, researchers unveil the genome of ito-mozuku (Nemacystus decipiens), the popular Japanese brown seaweed, providing data that could help farmers better grow the health food.

Tunas, sharks and ships at sea
Researchers combine maps of marine predator habitats with satellite tracks of fishing fleets to identify regions where they overlap -- a step toward more effective wildlife management on the high seas.

Review of noise impacts on marine mammals yields new policy recommendations
Marine mammals are particularly sensitive to noise pollution because they rely on sound for so many essential functions, including communication, navigation, finding food, and avoiding predators. An expert panel has now published a comprehensive assessment of the available science on how noise exposure affects hearing in marine mammals, providing scientific recommendations for noise exposure criteria that could have far-reaching regulatory implications.

Trust more important than ecology to gain local support for conservation
Trust, transparency, communication, and fairness in the planning and management of conservation projects may be more important for gaining long-term local support than emphasizing ecological effectiveness, research has discovered.

Cardiorespiratory fitness of farmed Atlantic salmon unaffected by virus
The respiratory systems of Atlantic salmon function normally even when carrying large loads of piscine orthoreovirus (PRV), new research has found. The results are a positive step in reducing the uncertainty about the potential of infected farmed Atlantic salmon in marine pens to negatively impact migrating wild Pacific salmon.

Unprecedented number of warm-water species moved northward during marine heatwave
A new study documents an unprecedented number of southern marine species moving northward into California and as far north as Oregon during the 2014-2016 marine heatwave. Of 67 rare, warm-water species sightings observed, 37 had never been documented so far north before.

Fatal horizon, driven by acidification, closes in on marine organisms in Southern Ocean
Marine microorganisms in the Southern Ocean may find themselves in a deadly vise grip by century's end as ocean acidification creates a shallower horizon for life.

No silver bullet for helping the Great Barrier Reef
Using a combination of advanced satellite imaging and over 20 years of coral monitoring across the Reef, a team of researchers has found that chronic exposure to poor water quality is limiting the recovery rates of corals across wide swaths of the Great Barrier Reef.

Horseshoe crabs are really relatives of spiders, scorpions
By analyzing troves of genetic data and considering a vast number of possible ways to examine it, scientists now have a high degree of confidence that horseshoe crabs do indeed belong within the arachnids.

Small animals with big impact
Copepods, the world's most common animal, release unique substances into the oceans. Concentrations of these substances are high enough to affect the marine food web, according to new research. The studies also show that phytoplankton in the oceans detect the special scent of copepods and do their utmost to avoid being eaten.

Coral reef parks protecting only 40 percent of fish biomass potential
Marine scientists examining the ecological status of coral reefs across the Indian and Pacific oceans have uncovered an unsettling fact: even the best coral reef marine parks contain less than half of the fish biomass found in the most remote reefs that lie far from human settlements.

Mathematics of sea slug movement points to future robots
Mathematicians recently discovered a lot of new, powerful geometries involved in frilly surfaces. They developed the mathematics to describe these surfaces -- inflected nonsmooth surfaces, which change the direction in which they bend -- and the combination of new geometry insights and age-old slugs might just be the right combination for a new generation of flexible, energy-efficient soft-bodied robots.
