Collision risk and habitat loss: Wind turbines in forests impair threatened bat species      (via sciencedaily.com) 

In order to meet climate protection goals, renewable energies are booming -- often wind power. More than 30,000 turbines have already been installed on the German mainland so far, and the industry is currently scrambling to locate increasingly rare suitable sites. Thus, forests are coming into focus as potential sites. A scientific team has now demonstrated that wind turbines in forests impair endangered bat species: Common noctules (Nyctalus noctula), a species with a high risk of colliding with rotor blades, are attracted to forest wind turbines if these are located near their roosts. Far from roosts, common noctules avoid the turbines, essentially resulting in a loss of foraging space and thus habitat for this species.

On the short-lived island of Hunga Tonga Hunga Ha'apai, researchers discovered a unique microbial community that metabolizes sulfur and atmospheric gases, similar to organisms found in deep sea vents or hot springs.

Biodiversity safeguards bird communities under a changing climate      (via sciencedaily.com) 

A new study shows that North American bird communities containing functionally diverse species have changed less under climate change during the past 50 years than functionally simple communities.

Our future climate depends partly on soil microbes -- but how are they affected by climate change?      (via sciencedaily.com)     Original source 

The largest terrestrial carbon sink on Earth is the planet's soil. One of the big fears is that a warming planet will liberate significant portions of the soil's carbon, turning it into carbon dioxide (CO2) gas, and so further accelerate the pace of planetary warming. A key player in this story is the microbe, the predominant form of life on Earth, and which can either turn organic carbon -- the fallen leaves, rotting tree stumps, dead roots and other organic matter -- into soil, or release it into the atmosphere as CO2. Now, an international team of researchers has helped to untangle one of the knottiest questions involving soil microbes and climate change: what effect does a warming planet have on the microbes' carbon cycling?

Climate conundrum: Study finds ants aren't altering behavior in rising temperatures      (via sciencedaily.com) 

A new study finds that ants are not adjusting their behavior in response to warming temperatures, persisting in sub-optimal microhabitats even when optimal ones were present. The finding suggests ants may not be able to adjust their behavior in response to warming ecosystems.

Better access to sunlight could be lifeline for corals worldwide      (via sciencedaily.com) 

When it comes to preserving the world's coral reefs, what's going on above the surface is as important as what's going on below it, according to new research.

Landscaping for drought: We're doing it wrong      (via sciencedaily.com)     Original source 

Despite recent, torrential rains, most of Southern California remains in a drought. Accordingly, many residents plant trees prized for drought tolerance, but a new study shows that these trees lose this tolerance once they're watered.

Climate 'presses' and 'pulses' impact Magellanic penguins -- a marine predator -- with guidance for conservationists      (via sciencedaily.com) 

Climate change will reshape ecosystems through two types of events: short-term, extreme events -- or 'pulses' -- and long-term changes, or 'presses.' Understanding the effects of presses and pulses is essential as conservationists and policymakers try to preserve ecosystems and safeguard biodiversity. Researchers have discovered how different presses and pulses impacted Magellanic penguins -- a migratory marine predator -- over nearly four decades and found that, though individual presses and pulses impacted penguins in a variety of ways, both were equally important for the future survival of the penguin population. They also found that these types of climate changes, taken together, are leading to an overall population decline at their historically largest breeding site.

Warming oceans have decimated marine parasites -- but that's not a good thing      (via sciencedaily.com) 

Save the ... parasites? Analyzing 140 years of parasite abundance in fish shows dramatic declines, especially in parasites that rely on three or more host species. The decline is linked to warming ocean temperatures. Parasitic species might be in real danger, researchers warn -- and that means not just fewer worms, but losses for the entire ecosystem.

Marine plankton tell the long story of ocean health, and maybe human too      (via sciencedaily.com) 

Researchers suggest that rising levels of humanmade chemicals, accumulating in marine plankton, might be used to monitor the impact of human activity on ecosystem health and perhaps study links between ocean pollution and land-based rates of childhood and adult chronic illnesses.

Study details impact of prairie dog plague die-off on other species      (via sciencedaily.com) 

This study, conducted from 2015-19 in the Thunder Basin National Grassland, may be the first to specifically examine the multispecies impacts of a wide-scale plague outbreak, which reduced the area covered by prairie dog colonies from nearly 25,000 acres to only about 125 acres in the study area. The 2017 outbreak was followed by abnormally high precipitation in 2018, which caused vegetation to grow quickly and taller without the presence of prairie dogs. The researchers found that the mountain plover, birds that thrive when vegetation is kept shorter by prairie dogs, almost disappeared from the study area, while migrant songbirds such as the lark bunting, which prefer taller vegetation, increased in number. Meanwhile, species including ferruginous hawks, badgers and swift foxes declined dramatically as their prey base crashed.

Invasive rats transform reef fish behavior      (via sciencedaily.com) 

Scientists have discovered for the first time that invasive rats on tropical islands are affecting the territorial behavior of fish on surrounding coral reefs. The new study shows that the presence of invasive black rats on tropical islands is causing changes in the territorial behavior of the jewel damselfish -- a herbivorous species of tropical reef fish that 'farm' algae in the branches of corals.

New York City's greenery absorbs a surprising amount of its carbon emissions      (via sciencedaily.com)     Original source 

A study of vegetation across New York City and some densely populated adjoining areas has found that on many summer days, photosynthesis by trees and grasses absorbs all the carbon emissions produced by cars, trucks and buses, and then some. The surprising result, based on new hyper-local vegetation maps, points to the underappreciated importance of urban greenery in the carbon cycle.

Palau's Rock Islands harbor heat-resistant corals      (via sciencedaily.com)     Original source 

Ocean warming is driving an increase in the frequency and severity of marine heatwaves, causing untold damage to coral reefs. Tropical corals, which live in symbiosis with tiny single celled algae, are sensitive to high temperatures, and exhibit a stress response called bleaching when the ocean gets too hot. In the last 4 decades, marine heatwaves have caused widespread bleaching, and killed millions of corals. Because of this, a global search is underway for reefs that can withstand the heat stress, survive future warming, and act as sources of heat-tolerant coral larvae to replenish affected areas both naturally and through restoration.
