Published Arctic shrub expansion limited by seed dispersal and wildfire


Scientists investigating the growth of Arctic vegetation have found that seed dispersal and fire will slow its land expansion in the long term, despite more favorable conditions from a warming planet.
Published Why corals glow even in the depths of the sea


A new study reveals that the phenomenon in deep reefs in which corals display glowing colors (fluorescence) is intended to serve as a mechanism for attracting prey. The study shows that the marine animals on which corals prey recognize the fluorescent colors and are attracted to them.
Published Air samples from Arctic region show how fast Earth is warming


Researchers report direct observations of size-resolved ice nucleating particles in the central Arctic, spanning the entire sea ice growth and decline cycle. Their results show a strong seasonality of these particles, with lower concentrations in the winter and spring, and enhanced concentrations during summer melt from local biology.
Published Ozone depletion over North Pole produces weather anomalies


Researchers have established that the destruction of ozone over the Arctic in the spring causes abnormal weather throughout the northern hemisphere, with many places being warmer and drier than average -- or too wet.
Published Birdwatching brings millions of dollars to Alaska


New research found that nearly 300,000 birders traveled to the state and spent about $378 million in 2016. Birdwatching supported roughly 4,300 jobs in Alaska that year.
Published Arctic temperatures are increasing four times faster than global warming


A new analysis of observed temperatures shows the Arctic is heating up more than four times faster than the rate of global warming. The trend has stepped upward steeply twice in the last 50 years, a finding missed by all but four of 39 climate models.
Published Thawing permafrost is shaping the global climate


How is climate change affecting the permanently frozen soils of the Arctic? What will the consequences be for the global climate, human beings, and ecosystems? And what can be done to stop it?
Published Genome of voracious desert locust sequenced


The first high-quality genome of the desert locust -- those voracious feeders of plague and devastation infamy and the most destructive migratory insect in the world -- has been produced. The genome of the desert locust (Schistocerca gregaria) is enormous at just under 9 billion base pairs, nearly three times the size of the human genome. The size of the desert locust's chromosomes is remarkable; compare them to those of the model fruit fly Drosophila melanogaster, the first insect genome ever assembled. Many of the desert locust's individual chromosomes are larger than the entire fruit fly genome. Next to the fruit fly, it's like an 18-wheeler next to a compact car.
Published Topology and machine learning reveal hidden relationship in amorphous silicon


Fine-tuning the thermal conductivity of amorphous silicon used in technologies such as solar cells and image sensors should become much easier thanks to the computational topology and machine-learning-assisted discovery of the relationship between nano-scale structures and physical properties.
Published Proactive approaches needed to enable ecosystems to adapt to climate change


As the need to address climate change becomes increasingly urgent so too does the concurrent need for proactive stewardship of the Earth's rapidly changing biosphere, according to new research.
Published Melting Arctic ice could transform international shipping routes, study finds


Melting ice in the Arctic Ocean could yield new trade routes in international waters, reducing the shipping industry's carbon footprint and weakening Russia's control over trade routes through the Arctic, a study found.
Published Mangrove and reef restoration yield positive returns on investment for flood protection, study shows


Restoration of mangroves and coral reefs can be a cost-effective solution for coastal flood reduction in more than 20 countries across the Caribbean. Researchers used methods from the risk and insurance industry to provide rigorous valuations of these natural defenses and show that they can deliver a positive return on investment, with the benefits from reduced flood damage exceeding the costs of restoration. The results point toward new opportunities to support restoration efforts with funds from sources that support hazard mitigation, climate adaptation, and disaster recovery, including FEMA.
Published Are new corals in Sydney dangerous invaders or harmless refugees?


A new study has found that invading subtropical corals will survive and thrive in coastal Sydney, which could spell trouble for existing Sydney coral species.
Published Newly documented population of polar bears in Southeast Greenland sheds light on the species' future in a warming Arctic


A new population of polar bears documented on the southeast coast of Greenland use glacier ice to survive despite limited access to sea ice. This small, genetically distinct group of polar bears could be important to the future of the species in a warming world.
Published Off-season cattle grazing to help control fire danger from invasive cheatgrass


Cheatgrass, an invasive annual grass that has invaded Nevada rangelands, is responsible for much of the increasing wildfire danger in the Intermountain West. However, scientists have discovered that fire danger can be reduced through the application of targeted cattle grazing in the dormant growing season by attracting the cattle with stations containing protein feed supplements.
Published Co-existing mangrove-coral habitats have a new global classification system


By coexisting more closely with mangroves, tropical coral species may have found an alternative habitat where they can thrive in the face of climate change.
Published Seagrass meadows are reliable fishing grounds for food


A new study in Ocean and Coastal Management shows that seagrass fisheries provide a reliable safety-net for poor, since fishermen perceive those habitats to maintain large fish catches over time. Surprisingly, even more so than coral reef fisheries, which people normally associate with small-scale fishery.
Published A warming climate decreases microbial diversity


Researchers conducted an eight-year experiment that found that climate warming played a predominant role in shaping microbial biodiversity, with significant negative effect.
Published Pioneering study shows climate played crucial role in changing location of ancient coral reefs


Prehistoric coral reefs dating back up to 250 million years extended much further away from the Earth's equator than today, new research has revealed.
Published Ningaloo corals are ill-equipped to handle future climate change


The relatively pristine coral populations of WA's inshore Kimberley region are better equipped to survive ocean warming than the World Heritage-listed Ningaloo Marine Park, according to a new study.
