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 Coffee and cocoa plants at risk from pollinator loss
(via sciencedaily.com) Original source Tropical crops such as coffee, cocoa, watermelon and mango may be at risk due to the loss of insect pollinators, finds a new study.
Published Tens of thousands of endangered sharks and rays caught off Congo
(via sciencedaily.com) Original source Tens of thousands of endangered sharks and rays are caught by small-scale fisheries off the Republic of the Congo each year, new research shows.
Published Remains of artificial turf is an important source of pollution of the aquatic environment
(via sciencedaily.com) Original source Every year, around 1,200 and 1,400 artificial turf sports fields are installed in the European Union. These fields are made up of synthetic fibers, mainly plastics, that mimic the appearance of natural grass. Recently, scientists conducted a study that characterizes and quantifies the presence of artificial turf fibers in samples collected from surface waters of the Catalan coast and the Guadalquivir River. The findings indicate that artificial turfs can be an important source of pollution in the aquatic environment, accounting for up to 15% of the plastics larger than 5 mm in length that are found floating in the aquatic environment.
Published Epiphytes, amazing plants like moss and bromeliads found in trees, face growing threats
(via sciencedaily.com) Original source Epiphytes, plants such as orchids and mosses that grow in trees, draw nutrients from the air and create refuge for all sorts of other life forms. They are the foundation of forest canopy ecosystems, but they are facing threats from human and natural disturbances.
Published Shining a light on tiny, solar-powered animals
(via sciencedaily.com) Original source Acoels have been found to host a wide diversity of symbiotic, photosynthetic microalgae.
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 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 A turtle time capsule: DNA found in ancient shell
(via sciencedaily.com) Original source Paleontologists discover possible DNA remains in fossil turtle that lived 6 million years ago in Panama, where continents collide.
Published Plastic cloud: New study analyzes airborne microplastics in clouds
(via sciencedaily.com) Original source Plastic waste that accumulates on land eventually ends up in the ocean as microplastics. However, it is now speculated that microplastics are also present in the atmosphere, contained in clouds. In a new study, researchers analyzed cloud water samples from high-altitude mountains in Japan to ascertain the amount of microplastics in them. They also shed light on how these airborne particles influence cloud formation and their negative impact on the climate.
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.
