Published 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.
Published Underground car parks heat up groundwater
(via sciencedaily.com) Original source The heat given off by car engines warms up underground car parks in such a way that the heat passes through the ground into the groundwater. In Berlin alone, enough energy is transferred to the groundwater to supply 14,660 households with heat. According to the researchers, this warming could have long-term effects on groundwater quality. In their study, they also propose a solution. Using geothermal energy and heat pumps, the heat could be extracted from the ground and utilized.
Published Self-powered microbial fuel cell biosensor for monitoring organic freshwater pollution
(via sciencedaily.com) Original source Biodegradable waste from plant and animal sources released into freshwater ecosystems is a significant environmental concern. Nonetheless, current methods for assessing water quality seem more or less impractical due to their complexity and high costs. In a promising development, a team of researchers has successfully constructed a self-sustaining and buoyant biosensor using inexpensive carbon-based materials for monitoring water quality at the inlets of freshwater lakes and rivers.
Published Investigators examine shifts in coral microbiome under hypoxia
(via sciencedaily.com) Original source A new study provides the first characterization of the coral microbiome under hypoxia, insufficient oxygen in the water.
Published Buzz around new centralized pollination portal for better global bee data
(via sciencedaily.com) Original source A powerful new way to fill major gaps in public bee data -- including from Africa, Asia and other under-reported zones -- has been addressed with a centralized tool for consolidating bee pollinator occurrences around the globe.
Published Giant dinosaur carcasses might have been important food sources for Jurassic predators
(via sciencedaily.com) Original source Carnivorous dinosaurs might have evolved to take advantage of giant carcasses, according to a new study.
Published The ringed seals in Ilulissat Icefjord, Greenland are special
(via sciencedaily.com) Original source Local hunters in the Icefjord near Ilulissat have long known about a special ringed seal -- the Kangia seal -- which is significantly larger and has a markedly different fur color and pattern than typical Arctic ringed seals. Now scientific studies have shown that the Kangia ringed seal has been isolated from other ringed seals for a long period of time -- more than 100,000 years.
Published Ocean warming is accelerating, and hotspots reveal which areas are absorbing the most heat
(via sciencedaily.com) Original source A new study reveals increasing warming rates in the world's oceans in recent decades and the locations with the greatest heat uptake.
Published 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.
Published Humans are disrupting natural 'salt cycle' on a global scale, new study shows
(via sciencedaily.com) Original source A new paper revealed that human activities are making Earth's air, soil and freshwater saltier, which could pose an 'existential threat' if current trends continue. Geologic and hydrologic processes bring salts to Earth's surface over time, but human activities such as mining and land development are rapidly accelerating this natural 'salt cycle.'
Published 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.
Published How common desert shrub efficiently harvests water from the air
(via sciencedaily.com) Original source A team of scientists has revealed the mechanism a desert plant native to the United Arab Emirates uses to capture moisture from the desert air in order to survive.
Published Australasia's hidden pollination crisis could threaten biodiversity and food security
(via sciencedaily.com) Original source Australasia's hidden pollination crisis, mirroring global threats, could pose a significant risk to regional biodiversity and food security, new research has found.
Published 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.
Published Study uncovers hundred-year lifespans for three freshwater fish species in the Arizona desert
(via sciencedaily.com) Original source New study finds some of the oldest animals in the world living in a place you wouldn't expect: fishes in the Arizona desert.
Published Amphibians have one more thing to worry about--mercury
(via sciencedaily.com) Original source The first widescale assessment of methylmercury in adult amphibians in the U.S. to date shows that, in amphibians, this toxic compound is common, widespread and, at least for some, can reach very high levels.
Published Offset markets: New approach could help save tropical forests by restoring faith in carbon credits
(via sciencedaily.com) Original source A new approach to valuing the carbon storage potential of natural habitats aims to help restore faith in offset schemes, by enabling investors to directly compare carbon credit pricing across a wide range of projects.
Published Two bee species become one as researchers solve identity puzzle
(via sciencedaily.com) Original source A new study has found that what were thought to be two different species of native Australian bee are in fact one.
Published 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.
Published Evolutionary chance made this bat a specialist hunter
(via sciencedaily.com) Original source It is generally believed that, for millions of years, bats and the insects they hunt at night have adapted to each other in an evolutionary arms race to become better at finding or avoiding each other. Now, a new study shows that this may not be the case at all.
