New species of moth named in honor of Donald Trump ahead of his swearing-in as president
Days before Donald J. Trump steps forward on the Presidential Inauguration platform in Washington on Jan. 20, an evolutionary biologist has named a new species in his honor. The researcher hopes that the fame around the new moth will successfully point to the critical need for further conservation efforts for fragile areas such as the habitat of the new species.

Conditions right for complex life may have come and gone in Earth's distant past
Conditions suitable to support complex life may have developed in Earth's oceans -- and then faded -- more than a billion years before life truly took hold, a new study has found.

Signs of hope for endangered sea turtles
Bones from dead turtles washed up on Mexican beaches indicate that Baja California is critical to the survival of endangered North Pacific loggerhead sea turtles, which travel some 7,500 miles from their nesting sites in Japan to their feeding grounds off the coast of Mexico.

Fossils found reveal unseen 'footprint' maker
Fossils found in Morocco from the long-extinct group of sea creatures called trilobites, including rarely seen soft-body parts, may be previously unseen animals that left distinctive fossil 'footprints' around the ancient supercontinent Gondwana.

How China is poised for marine fisheries reform
China has introduced an unprecedented policy platform for stewarding its fisheries and other marine resources. In order to achieve a true paradigm shift a team of international scientists from within and outside of China recommend major institutional reform.

Genome sequence of polar alga explains evolutionary adaptation to extreme variable climate
An international team of researchers has identified the genetic mutations which allowed microalgae (phytoplankton) from the Southern Ocean to adapt to extreme and highly variable climates -- a step towards understanding how polar organisms are impacted by climate change.

Tracking Antarctic adaptations in diatoms
In the Antarctic Ocean, large populations of the diatom Fragillariopsis cylindrus dominate the phytoplankton communities. To learn more about how F. cylindrus adapted to its extremely cold environment, a team of researchers conducted a comparative genomic analysis involving three diatoms. The results provided insights into the genome structure and evolution of F. cylindrus, as well as this diatom's role in the Southern Ocean.

Diversification key to resilient fishing communities
Fishing communities can survive, and even thrive, as fish abundance and market prices shift if they can catch a variety of species and nimbly move from one fishery to the next, a new study finds.

How to be winner in the game of evolution
A new study helps explain why different groups of animals differ dramatically in their number of species, and how this is related to differences in their body forms and ways of life.

Reef fish that conquer fear of sharks may help control excess algae
Coral reef fish experience landscapes of fear based on how much shelter from predators is available, new research concludes. But they are willing to move past that fear if the payoff in a delicious meal of algae is high enough, the investigators found.

How the darkness and the cold killed the dinosaurs
Climate scientists now reconstructed how tiny droplets of sulfuric acid formed high up in the air after the well-known impact of a large asteroid and blocking the sunlight for several years, had a profound influence on life on Earth.

Ocean acidification to hit West Coast Dungeness crab fishery, new assessment shows
The acidification of the ocean expected as seawater absorbs increasing amounts of carbon dioxide from the atmosphere will reverberate through the West Coast's marine food web, but not necessarily in the ways you might expect, new research shows.

This bay in Scandinavia has world record in carbon storing
Forests are potent carbon sinks, but also the oceans' seagrasses can store enormous amounts of carbon. A little bay in Denmark stores a record amount of carbon. Here is the secret.

Paleontologists classify mysterious ancient cone-shaped sea creatures
One branch on the tree of life is heavier as a team of scientists has determined what a bizarre group of extinct cone-shaped animals actually are. Known as hyoliths, these marine creatures evolved over 530 million years ago and are among the first known to have external skeletons. Long believed to be molluscs, a new study shows a stronger relationship to brachiopods -- a group with a rich fossil record though few species living today.

Wastewater treatment upgrades result in major reduction of intersex fish
Upgrades to a wastewater treatment plant along Ontario's Grand River, led to a 70 per cent drop of fish that have both male and female characteristics within one year and a full recovery of the fish population within three years, according to researchers.

Warmer West Coast ocean conditions linked to increased risk of toxic shellfish
Hazardous levels of domoic acid, a natural toxin that accumulates in shellfish, have been linked to warmer ocean conditions in waters off Oregon and Washington for the first time, report scientists.

Retroviruses 'almost half a billion years old'
Retroviruses -- the family of viruses that includes HIV -- are almost half a billion years old, according to new research. That's several hundred million years older than previously thought and suggests retroviruses have ancient marine origins, having been with their animal hosts through the evolutionary transition from sea to land. The findings will help us understand more about the continuing 'arms race' between viruses and their hosts.
