"Resilience" is a buzzword often used in scientific literature to describe how animals, plants and landscapes can persist under climate change. It’s typically considered a good quality, suggesting that those with resilience can withstand or adapt as the climate continues to change.

But when it comes to actually figuring out what makes a species or an entire ecosystem resilient ― and how to promote that through restoration or management ― there is a lack of consensus in the scientific community.

Forests play a complex role in keeping the planet cool, one that goes far beyond the absorption of carbon dioxide, new research has found.

Trees also impact climate by regulating the exchange of water and energy between the Earth’s surface and the atmosphere, an important influence that should be considered as policymakers contemplate efforts to conserve forested land, said the authors of an international study that appears in the journal Nature Climate Change.

Collecting dust isn't usually considered a good thing.

But dust from as close as California's Central Valley and as far away as Asia's Gobi Desert provides nutrients, especially phosphorus, to vegetation in the Sierra Nevada Mountains, a team of scientists has found. Their study, published in the journal Nature Communications, highlights the importance of dust and the phosphorus it carries in sustaining plant life.

William Blake may have seen a world in a grain of sand, but for scientists at MIT the smallest of all photosynthetic bacteria holds clues to the evolution of entire ecosystems, and perhaps even the whole biosphere.

Where is marine litter concentrated, and which species and ecosystems does it affect? Researchers at the Alfred Wegener Institute have for the first time compiled all scientific data published on marine litter in a single, comprehensive database, now accessible from the online portal AWI Litterbase (www.litterbase.org). Here, both the distribution of litter and its interactions with organisms are presented in global maps. In addition, the regularly updated datasets are fed into graphic analyses, which show e.g. that seabirds and fish are particularly affected by litter. The latest interaction analysis shows that 34 per cent of the species monitored ingest litter, 31 per cent colonise it, and 30 per cent get entangled or otherwise trapped in it (for all figures: valid as of 23 March 2017). The total number of affected species is rising steadily and is currently at 1,220 – more than twice the number reported in the last review article. These numbers will change as the database is being updated regularly.

Tests conducted this week of a novel technology that can greatly accelerate the combustion of crude oil floating on water demonstrated its potential to become an effective tool for minimizing the environmental impact of future oil spills. Called the Flame Refluxer, the technology, developed by fire protection engineering researchers at Worcester Polytechnic Institute (WPI) with funding from the Bureau of Safety and Environmental Enforcement (BSEE), could make it possible to burn off spilled oil quickly while producing relatively low levels of air pollutants.

The tests of the Flame Refluxer were conducted this week by WPI and BSEE at the United States Coast Guard’s Joint Maritime Test Facility on Little Sand Island, located in Mobile Bay. WPI is the first university to work on research at the facility since it reopened in 2015. The tests involved controlled burns of oil in a specially designed test tank on the island.

In the South China Sea, a 2°C rise in the sea surface temperature in June 2015 was amplified to produce a 6°C rise on Dongsha Atoll, a shallow coral reef ecosystem, killing approximately 40 percent of the resident coral community within weeks, according to a study published in Scientific Reports this week.

Wind and waves churn the sea, flushing shallow-water coral reefs with seawater from the open ocean to help them stay cool. But according to new research from the Woods Hole Oceanographic Institution (WHOI), when the weather turns still and these natural cooling mechanisms subside, just a few degrees of ocean warming can prove lethal to the corals that live there.

Among ecologists, carbon gets all the glory. Scientists examine its critical role in plant growth and decay, they chart its contributions to greenhouse gases, and they measure its sequestration in earth, sea, and sky.

Often overlooked in all this research is the humble element silicon, or “silica,” as it’s called when found in nature. If ecologists (or biologists or biogeochemists) think of silica at all, they regard it as a bit player, a ho-hum component of rocks and sand.

New research supports the creation of more marine reserves in the world’s oceans because, the authors say, fish can evolve to be more cautious and stay away from fishing nets.

Tasty, versatile, and rich in essential omega-3 fatty acids: salmon is one of the most popular edible fish of all. Shops sell fish caught in the wild, but their main produce is salmon from breeding farms which can pollute rivers, lakes and oceans. Just how big is the problem? German and Chilean scientists are working to answer this question under the leadership of the Helmholtz Centre for Environmental Research (UFZ). They examined the dissolved organic compounds which enter Chile's rivers from salmon farms, and have published a report in the journal Scientific Reports, warning that these substances are placing huge strain on ecosystems and are changing entire biological communities.
