Published When in drought: Researchers map which parts of the Amazon are most vulnerable to climate change
(via sciencedaily.com) Original source Some areas of the Amazon rainforest are more resilient to drought than others, new research shows. But if not managed carefully, we could 'threaten the integrity of the whole system,' researchers say.
Published Climate change: rising temperatures may impact groundwater quality
(via sciencedaily.com) Original source As the world's largest unfrozen freshwater resource, groundwater is crucial for life on Earth. Researchers have investigated how global warming is affecting groundwater temperatures and what that means for humanity and the environment. Their study indicates that by 2100, more than 75 million people are likely to be living in regions where the groundwater temperature exceeds the highest threshold set for drinking water by any country.
Published A conservation market could incentivize global ocean protection
(via sciencedaily.com) Original source Thirty-by-thirty: protect 30% of the planet by 2030. While conservation is popular in principle, the costs of actually enacting it often stall even the most earnest efforts. Researchers have now proposed a market-based approach to achieving the 30x30 targets in the ocean.
Published Marine heatwaves devastate red gorgonians in the Medes Islands
(via sciencedaily.com) Original source The increase in the frequency and intensity of marine heatwaves in recent decades is one of the effects of global climate change. A study shows that the extreme heatwave of 2022 caused an 'unprecedented' increase in mortality of the red gorgonian Paramuricea clavata, affecting 70% of the colonies located in the Montgr Natural Park, the Medes Islands and the Baix Ter. According to the researchers, these results are 'alarming and threaten the viability' of this species of great value for the biodiversity of benthic ecosystems, since it is considered to be an inhabitant-forming species.
Published Cocaine trafficking threatens critical bird habitats
(via sciencedaily.com) Original source In addition to its human consequences, cocaine trafficking harms the environment and threatens habitats important to dozens of species of migratory birds, according to a new study.
Published Specialist and migratory birds at greater risk under climate change
(via sciencedaily.com) Original source Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis. The study examines the long-term effects of climate change on the abundance and diversity of bird groups across the continent as a whole while accounting for additional factors that put birds at risk.
Published Upstream and downstream: River study highlights cross-country inequities
(via sciencedaily.com) Original source New research highlights inequities between downstream and upstream countries that share the same watershed. The study outlines how international agreements can better address shared resource problems and call for greater collaboration and coordination between these international neighbors.
Published Tropical forests adjust strategies to thrive even when soils are nutrient poor
(via sciencedaily.com) Original source Tropical forests store a third of the world's carbon in their wood and soils. However, their future as a carbon sink has been uncertain. Scientists have long wondered whether nutrient-poor tropical soils would limit the ability of mature and recovering forests to thrive. A study offers a hopeful response, suggesting that forests have flexible strategies that help them overcome the challenge of scarce nutrients.
Published Early summer fishing can have an evolutionary impact, resulting in smaller salmon
(via sciencedaily.com) Original source A new genetic study found that heavy fishing in the early part of the fishing season may result in younger and smaller Atlantic salmon. This information can help to conserve large fish essential for the diversity and viability of salmon populations.
Published A novel approach to tracking conservation reveals more areas may be conserved than currently accounted for
(via sciencedaily.com) Original source An international team of conservation researchers and practitioners has developed an inclusive inventory approach for tracking global conservation areas, with an emphasis on local data and expertise. Applying this approach across the nine countries spanning the Amazon Rainforest identified a wide array of conservation areas with greater diversity and area coverage than existing tracking systems showed.
Published Exploring three frontiers in marine biomass and blue carbon capture
(via sciencedaily.com) Original source A new study offers first-time insights into three emerging climate innovations to safeguard or increase the carbon naturally captured by ocean and coastal ecosystems: rapid interventions to save the Great Barrier Reef, satellite-tracked kelp beds in the deep ocean, and seagrass nurseries in the United Kingdom.
Published Centering relationships between people and place: A critical step towards improving science's contributions to society
(via sciencedaily.com) Original source Marine conservation scientists advocate for a cultural shift in academia that fosters deeper connections with places of study and encourages collaboration with local communities to make science more relevant, equitable and meaningful.
Published Mapping the seafloor sediment superhighway
(via sciencedaily.com) Original source A new scientific model is giving researchers an unprecedented, global look at the activities of clams, worms, and other invertebrate animals that burrow at the bottom of the ocean.
Published Urgent need for action now for increasing threat from invasive alien species
(via sciencedaily.com) Original source Urgent action now is needed to tackle the major and growing global issue of invasive alien species, says a team of 88 experts from 47 countries. The paper follows the (IPBES) thematic assessment report on invasive alien species and their control. The experts say co-developing management actions with multiple stakeholders including government and private sector stakeholders, and Indigenous Peoples and local communities will be critical to achieving success in addressing biological invasions.
Published People are altering decomposition rates in waterways
(via sciencedaily.com) Original source Humans may be accelerating the rate at which organic matter decomposes in rivers and streams on a global scale, according to a new study. That could pose a threat to biodiversity in waterways around the world and increase the amount of carbon in Earth's atmosphere, potentially exacerbating climate change. The study is the first to combine a global experiment and predictive modeling to illustrate how human impacts to waterways may contribute to the global climate crisis.
Published Rapid urbanization in Africa transforms local food systems and threatens biodiversity
(via sciencedaily.com) Original source Urbanization in Africa is accelerating quickly, showing no signs of slowing down. An international team of researchers addresses critical gaps in our understanding of how this urbanization affects local food and ecological systems, emphasizing the importance of recognizing shifts in dietary patterns.
Published Antibiotic pollution disrupts the gut microbiome and blocks memory in aquatic snails
(via sciencedaily.com) Original source Antibiotics prevent snails from forming new memories by disrupting their gut microbiome -- the community of beneficial bacteria found in their guts.
Published What makes some plant groups so successful?
(via sciencedaily.com) Original source Researchers involved in cataloguing the world's plant species are hunting for answers as to what makes some groups of plants so successful. One of their major goals is to predict more accurately which lineages of flowering plants -- some of which are of huge importance to people and to ecosystems -- are at a greater risk from global climate change.
Published Fatal attraction: When endangered species try to mate with domestic relatives, both wildlife and people lose
(via sciencedaily.com) Original source Sticks and stones aren't enough to thwart biological attraction, but sometimes those are the only tools available to pastoralists trying to prevent wildlife from eloping with their livestock. A new study brings awareness to both the human impacts of these encounters -- ranging from economic loss to death -- and conservation concerns for the wild animals that are often endangered.
Published Some species may tolerate climate change better than expected
(via sciencedaily.com) Original source A new model reassesses the proportion of terrestrial and marine species threatened with extinction by climate change. While the forecasts of traditional models estimate that the diversity of terrestrial species in tropical areas could decrease by 54% between now and 2041-2060, this model is more moderate, predicting a decrease of 39%. Nevertheless, this proportion remains alarming and confirms the importance of taking urgent measures to mitigate climate change and its impact on biodiversity.
