Two fins are better than one: Fish synchronize tail fins to save energy      (via sciencedaily.com)     Original source 

They say two heads are better than one. But in the world of fish, it appears two fins are better than one. Researchers have produced a theoretical model that demonstrates the underlying mechanisms behind how fish will synchronize their fin movements to ride each other's vortices, thereby saving energy.

Crust-forming algae are displacing corals in tropical waters worldwide      (via sciencedaily.com)     Original source 

Over the past few decades, algae have been slowly edging corals out of their native reefs across the globe by blocking sunlight, wearing the corals down physically, and producing harmful chemicals. But in recent years, a new type of algal threat has surfaced in tropical regions like the Caribbean -- one that spreads quickly and forms a crust on top of coral and sponges, suffocating the organisms underneath and preventing them from regrowing. Marine biologists report that peyssonnelioid alga crusts, or PACs, are expanding quickly across reefs worldwide, killing off corals and transforming entire ecosystems.

Large herbivores such as elephants, bison and moose contribute to tree diversity      (via sciencedaily.com)     Original source 

Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall.

To restore ecosystems, think about thwarting hungry herbivores      (via sciencedaily.com)     Original source 

Re-establishing plantings of trees, grasses and other vegetation is essential for restoring degraded ecosystems, but a new survey of almost 2,600 restoration projects from nearly every type of ecosystem on Earth finds that most projects fail to recognize and control one of the new plants' chief threats: hungry critters that eat plants.

Adult coral can handle more heat and keep growing thanks to heat-evolved symbionts      (via sciencedaily.com)     Original source 

Adult fragments of a coral species can better tolerate bleaching and recover faster when treated with tougher heat-evolved symbionts, new research indicates. The study also found that treatment with the heat-evolved symbionts did not compromise the coral's ability to grow. This differs from previous studies on Great Barrier Reef corals which found that naturally heat tolerant symbionts could enhance heat resistance in adult corals, but at a cost to its growth.

Where is a sea star's head? Maybe just about everywhere      (via sciencedaily.com)     Original source 

A new study that combines genetic and molecular techniques helps solve the riddle of sea star (commonly called starfish) body plans, and how sea stars start life with bilateral body symmetry -- just like humans -- but grow up to be adults with fivefold 'pentaradial' symmetry.

Dam removals, restoration project on Klamath River expected to help salmon, researchers conclude      (via sciencedaily.com)     Original source 

The world's largest dam removal and restoration project currently underway on the Klamath River in Oregon and California will aid salmon populations that have been devastated by disease and other factors. However, it will not fully alleviate challenges faced by the species, a team of researchers conclude.

Shifting nesting timing not enough to prevent fewer sea turtle hatchlings      (via sciencedaily.com)     Original source 

New research shows that potential adaptive responses by sea turtles, such as shifting the timing of when they nest, may not be enough to counteract the projected impacts from climate change on hatchling production.

Researchers observe wolves hunting and killing sea otters and harbor seals on Alaska's Katmai coast      (via sciencedaily.com)     Original source 

Firsthand observations of a wolf hunting and killing a harbor seal and a group of wolves hunting and consuming a sea otter on Alaska's Katmai coast have led scientists to reconsider assumptions about wolf hunting behavior.

Amazon deforestation linked to long distance climate warming      (via sciencedaily.com)     Original source 

Deforestation in the Amazon causes land surfaces up to 100 kilometers away to get warmer, suggests a new study.   The research suggests that tropical forests play a critical role in cooling the land surface -- and that effect can play out over considerable distances.

Low-income countries could lose 30% of nutrients like protein and omega-3 from seafood due to climate change      (via sciencedaily.com)     Original source 

The nutrients available from seafood could drop by 30 per cent for low-income countries by the end of the century due to climate change, suggests new research. That's in a high carbon emissions and low mitigation scenario, according to the study. This could be reduced to a roughly 10 per cent decline if the world were to meet the Paris Agreement targets of limiting global warming to 1.5 to 2 degrees Celsius -- which recent reports have shown we're not on track to achieve.

New species of mosasaur named for Norse sea serpent      (via sciencedaily.com)     Original source 

Scientists have discovered a new species of mosasaur, large, carnivorous aquatic lizards that lived during the late Cretaceous. With 'transitional' traits that place it between two well-known mosasaurs, the new species is named after a sea serpent in Norse mythology, Jormungandr, and the small North Dakota city Walhalla near to where the fossil was found.

Increasing risk of invasive species colonization on marine debris      (via sciencedaily.com)     Original source 

A groundbreaking scientific study conducted along the Southeast coast of India has unearthed a pressing environmental concern -- the increasing risk of invasive species colonization on marine debris. The research delves into the critical interplay between plastic pollution and the introduction of non-indigenous organisms into Indian waters.

UK air pollution regulations will reduce deaths, but do little to protect ecosystems      (via sciencedaily.com)     Original source 

Existing air pollution regulations will reduce thousands of premature adult deaths in the UK, but even the most effective technically feasible actions, which will save thousands more lives, will do little to protect the country's sensitive ecosystems, find researchers.
