Published New mollusk and crustacean species in symbiosis with worms in dead coral rocks
(via sciencedaily.com) Original source The symbiotic communities of invertebrates in dead coral gravel on the shallow, warm-temperate coast of the Kii Peninsula in western Japan. New bivalve species and sideswimmer have been found to live communally with the greenish Bonellia spoonworm. Live-in symbionts share the burrows of other organisms in sand and mud on the seabed. However, studies on burrow niches in rigid substrates, such as rocks on the seabed, have been scarce.
Published Subalpine forests in the Northern Rockies are fire resilient--for now
(via sciencedaily.com) Original source Using lake sediment cores, scientists determined how these subalpine ecosystems recovered after 4,800 years of fire.
Published Climate change coping mechanism discovered in humble algae
(via sciencedaily.com) Original source One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops.
Published Wildfires threaten environmental gains in climate-crucial Amazon
(via sciencedaily.com) Original source Despite steps toward decreasing deforestation, uncontrolled wildfires are threatening environmental gains in Brazilian Amazonia, one of the world's most critical carbon sinks and a region of high biological and cultural diversity.
Published Invertebrate biodiversity is improving in England's rivers, long-term trends show
(via sciencedaily.com) Original source Rivers across England have seen a significant improvement in river invertebrate biodiversity since 1989, shows a new study.
Published Volcanic ash effects on Earth systems
(via sciencedaily.com) Original source To bridge the knowledge gap between volcanologists and atmospheric scientists working on climate change and observing global systems, researchers have characterized volcanic ash samples from many explosive eruptions of a broad compositional range.
Published Carbon-capture tree plantations threaten tropical biodiversity for little gain, ecologists say
(via sciencedaily.com) Original source The increasingly urgent climate crisis has led to a boom in commercial tree plantations in an attempt to offset excess carbon emissions. However, authors argue that these carbon-offset plantations might come with costs for biodiversity and other ecosystem functions. Instead, the authors say we should prioritize conserving and restoring intact ecosystems.
Published Improved mangrove conservation could yield cash, carbon, coastal benefits
(via sciencedaily.com) Original source A shift in the way we think about the benefits mangroves provide to coastal regions could yield significant economic and biodiversity gains and protect millions from flooding, research has revealed.
Published Viruses dynamic and changing after dry soils are watered
(via sciencedaily.com) Original source Viruses in soil may not be as destructive to bacteria as once thought and could instead act like lawnmowers, culling older cells and giving space for new growth, according to research.
Published Study on mysterious Amazon porcupine can help its protection
(via sciencedaily.com) Original source A recent study sheds new light on the elusive Roosmalens' dwarf porcupine, a poorly understood neotropical species. After 22 years of relative obscurity, this research uncovers vital information about its distribution, phylogenetics, and potential conservation threats, not only revealing its endemic presence in the Madeira biogeographical province but also expanding its known range in the southern Amazon.
Published Climate and human land use both play roles in Pacific island wildfires past and present
(via sciencedaily.com) Original source It’s long been understood that human settlement contributes to conditions that make Pacific Islands more susceptible to wildfires, such as the devastating Aug. 8 event that destroyed the Maui community of Lahaina. But a new study from fire scientist shows that climate is an undervalued part of the equation.
Published Important additional driver of insect decline identified: Weather explains the decline and rise of insect biomass over 34 years
(via sciencedaily.com) Original source Combinations of unfavorable weather conditions over several years can cause a decline in insect biomass.
Published Protecting lands slows biodiversity loss among vertebrates by five times
(via sciencedaily.com) Original source Protecting large swaths of Earth's land can help stem the tide of biodiversity loss -- especially when those protected areas are in less disturbed landscapes and in countries with effective national governance. A new study looked at how amphibians, reptiles, mammals and birds fared in protected versus unprotected areas worldwide. Vertebrate abundance decreased five times more slowly inside protected areas, offering much-needed support for the United Nations' '30 by 30' conservation initiative.
Published How to save plants from climate change? Just ask them
(via sciencedaily.com) Climate change and a range of human-caused factors have disrupted the habitats of many California native trees and other plant species. Efforts to protect or relocate plant species would be bolstered by understanding which habitats are best suited for each species. A new study identified a range of characteristics from more than 100 types of plants that can be analyzed to determine each species' preferred temperature and rainfall amount.
Published Theories about the natural world may need to change to reflect human impact
(via sciencedaily.com) New research has validated at scale, one of the theories that has underpinned ecology for over half a century. In doing so, the findings raise further questions about whether models should be revised to capture human impacts on natural systems.
Published Despite being properly treated and highly diluted, wastewater still impacts on the river ecosystem
(via sciencedaily.com) Original source An experiment using water from a large wastewater treatment plant has shown that this water continues to affect river diversity and the trophic web (food web) despite being properly treated and highly diluted before discharge. The study shows that the limits currently in place and the procedures used to treat wastewater may not be sufficient to protect the natural properties of food webs.
Published By air, rain and land: How microbes return after a wildfire
(via sciencedaily.com) Ecological disturbances like wildfires disrupt microbial communities. Researchers found that dispersal played a pivotal role in re-establishing surface-level communities.
Published How climate warming could disrupt a deep-rooted relationship
(via sciencedaily.com) Trees depend on fungi for their well-being. As climate change and global warming cause higher temperatures and amplified drought, little is known about how these important fungi will respond. To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their tree hosts respond to environmental changes. Their findings revealed that the combined effects of warming and water stress will likely result in major disturbances of ectomycorrhizal networks and may harm forest resilience and function.
Published Crucial third clue to finding new diamond deposits
(via sciencedaily.com) Researchers studying diamond-rich rocks from Western Australia's Argyle volcano have identified the missing third key ingredient needed to bring valuable pink diamonds to the Earth's surface where they can be mined, which could greatly help in the global hunt for new deposits.
Published Incubator or barrier? Exploring the links between agriculture, biodiversity and the spread of pathogens
(via sciencedaily.com) Many pathogens, including the virus that causes COVID-19, are thought to have originated in wild animals before spilling into human populations.
