Pollutants are important to biodiversity's role in spread of wildlife diseases      (via sciencedaily.com) 

Conventional wisdom among ecologists holds that the more species there are inhabiting an ecosystem, the less vulnerable any one species will be to a threat like a parasite. A new study of tadpoles illustrates how overlapping biological and environmental factors can complicate how we value protecting diverse animal communities. The researchers found that environmental pollutants like road salt influence whether increased biodiversity helps or hinders disease outbreaks in wildlife, which can complicate how we value protecting diverse animal communities.

Pause in recent coral recovery on much of Great Barrier Reef      (via sciencedaily.com) 

In-water monitoring shows hard coral cover across the Great Barrier Reef remains at similar levels to that recorded in 2022, with small decreases in the Northern, Central and Southern regions. AIMS' Annual Summary Report on Coral Reef Condition for 2022/23 found that while some reefs continued to recover, their increased hard coral cover was offset by coral loss on other reefs. Most reefs underwent little change in coral cover.

City-dwelling wildlife demonstrate 'urban trait syndrome'      (via sciencedaily.com) 

City life favors species that are adaptable and not too fussy about what they eat, among other characteristics. A worldwide consortium of scientists calls the resulting collection of traits an 'Urban Trait Syndrome.'

Carbon dioxide -- not water -- triggers explosive basaltic volcanoes      (via sciencedaily.com)     Original source 

Geoscientists have long thought that water -- along with shallow magma stored in Earth's crust -- drives volcanoes to erupt. Now, thanks to newly developed research tools, scientists have learned that gaseous carbon dioxide can trigger explosive eruptions.

Scientists crack the code of what causes diamonds to erupt      (via sciencedaily.com)     Original source 

Scientists have discovered that the breakup of tectonic plates is the main driving force behind the generation and eruption of diamond-rich magmas from deep inside the Earth.

In the treetops: Ecologist studies canopy soil abundance, chemistry      (via sciencedaily.com)     Original source 

Ecologists examined the distribution patterns of canopy soils, and their soil properties, across Costa Rican forests. The researchers suggest canopy soil may store more carbon than previously thought. Consideration of the time needed for reforestation of system with tree canopies should include the time needed for canopy mat regrowth.

Invasion of the Arctic Ocean by Atlantic plankton species reveals a seasonally ice-free ocean during the last interglacial      (via sciencedaily.com)     Original source 

A subpolar species associated with Atlantic water expanded far into the Arctic Ocean during the Last Interglacial, analysis of microfossil content of sediment cores reveals. This implies that summers in the Arctic were ice free during this period.

Research reveals Hawai'i's undersea volcano, Kama'ehu, erupted five times in past 150 years      (via sciencedaily.com)     Original source 

Kama?ehuakanaloa (formerly L??ihi Seamount), a submarine Hawaiian volcano located about 20 miles off the south coast of the Big Island of Hawai'i, has erupted at least five times in the last 150 years, according to new research led by Earth scientists at the University of Hawai'i at M?noa.

Past climate warming driven by hydrothermal vents      (via sciencedaily.com)     Original source 

An international drilling expedition off the Norwegian coast confirms the theory that methane emissions from hydrothermal vents were responsible for global warming about 55 million years ago. The study shows that the vents were active in very shallow water depth or even above sea level, which would have allowed much larger amounts of methane to enter the atmosphere.

Scientists dig into wildfire predictions, long-term impacts      (via sciencedaily.com)     Original source 

Wildfires are an ancient force shaping the environment, but they have grown in frequency, range and intensity in response to a changing climate. Scientists are working on several fronts to better understand and predict these events and what they mean for the carbon cycle and biodiversity.

Nature's kitchen: how a chemical reaction used by cooks helped create life on Earth      (via sciencedaily.com)     Original source 

A chemical process used in the browning of food to give it its distinct smell and taste is probably happening deep in the oceans, where it helped create the conditions necessary for life. Known as the Maillard reaction after the French scientist who discovered it, the process converts small molecules of organic carbon into bigger molecules known as polymers. In the kitchen, it is used to create flavors and aromas out of sugars. But a research team argues that on the sea floor, the process has had a more fundamental effect, where it has helped to raise oxygen and reduce carbon dioxide levels in the atmosphere, to create the conditions for complex life forms to emerge and thrive on Earth.

Study analyzes nearshore California marine heatwaves and cold spells amid changing climate conditions      (via sciencedaily.com)     Original source 

Human-caused climate change has also caused extreme ocean temperatures and conditions with detrimental impacts on marine ecosystems and ocean-related ecology.  A new study explores ocean temperature data along California's Coast, finding that certain environmental conditions and the state of the ocean led to an enhanced risk for marine heatwaves and cold spells, conditions that scientists and environmental managers will need to monitor to preserve and protect vital ecosystems critical to the California ocean economy, known as the Blue Economy.

Dune patterns reveal environmental change on Earth and other planets      (via sciencedaily.com)     Original source 

Researchers have analyzed the shifting patterns of entire dune fields on Earth and Mars, as seen from orbit, and found they are a direct signature of recent environmental change. This new tool can be applied anywhere with dunes, such as Mars, Titan, and Venus.
