Published Historic iceberg surges offer insights on modern climate change
(via sciencedaily.com) Original source A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs. And the havoc it wrought was to the ocean current itself. The future of the Atlantic circulation will be determined by a tug-o-war between Greenland's decreasing ice flux and its increasing freshwater runoff.
Published Local bright spot among melting glaciers: 2000 km of Antarctic ice-covered coastline has been stable for 85 years
(via sciencedaily.com) Original source A whaler's forgotten aerial photos from 1937 have given researchers the most detailed picture of the ice evolution in East Antarctica to date. The results show that the ice has remained stable and even grown slightly over almost a century, though scientists observe early signs of weakening. The research offers new insights that enhance predictions of ice changes and sea level rise.
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 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.
Published Marine Protected Areas don't line up with core habitats of rare migratory fish, finds new research
(via sciencedaily.com) Original source 62% of Marine Protected Areas (MPAs) designated to protect rare migratory fish species are outside of their core habitats, according to a new modeling study.
Published Global activity of seafloor biodiversity mapped
(via sciencedaily.com) Original source A team of scientists has used artificial intelligence (AI) to map the activities of seafloor invertebrate animals, such as worms, clams and shrimps, across all the oceans of the world.
Published Warmer wetter climate predicted to bring societal and ecological impact to the Tibetan Plateau
(via sciencedaily.com) Original source According to a paper, climate and weather predictions of increased rainfall will lead to an exponential expansion of land-locked lakes on the Tibetan Plateau, resulting in major land loss and related economic, environmental and climatic impacts.
Published Future climate impacts put whale diet at risk
(via sciencedaily.com) Original source A new study predicts future climate change impacts could disrupt the krill-heavy diet that humpback whales in the southern hemisphere consume.
Published Smoke covered 70% of California during biggest wildfire years
(via sciencedaily.com) Original source As much as 70 percent of California was covered by wildfire smoke during parts of 2020 and 2021, according to a new study.
Published Conservation of nature's strongholds needed to halt biodiversity loss
(via sciencedaily.com) Original source To achieve global biodiversity targets, conservationists and governments must prioritize the establishment and effective management of large, interconnected protected areas with high ecological integrity, researchers argue in a new essay.
Published Regional differences in bird diversity in agroforestry systems
(via sciencedaily.com) Original source The diversity and ecological functionality of bird communities in tropical agroforestry systems are shaped by the surrounding landscape, in particular the extent and composition of the forest.
Published A rise in sea urchins and related damage to kelp forests impacts Oregon's gray whales and their food
(via sciencedaily.com) Original source A recent boom in the purple sea urchin population off the southern Oregon Coast appears to have had an indirect and negative impact on the gray whales that usually forage in the region, a new study shows.
Published New research reveals that prehistoric seafloor pockmarks off the California coast are maintained by powerful sediment flows
(via sciencedaily.com) Original source New research on a field of pockmarks -- large, circular depressions on the seafloor -- offshore of Central California has revealed that powerful sediment flows, not methane gas eruptions, maintain these prehistoric formations.
Published Digging up good news for microbial studies
(via sciencedaily.com) Original source Findings indicate that soil stored under refrigerated or air-dried conditions can still retain the needed information for understanding microbial community composition and structure for many years.
Published Record low Antarctic sea ice 'extremely unlikely' without climate change
(via sciencedaily.com) Original source Scientists have found that the record-low levels of sea ice around Antarctica in 2023 were extremely unlikely to happen without the influence of climate change. This low was a one-in-a-2000-year event without climate change and four times more likely under its effects.
Published Early arrival and expansion of palaeolithic people on Cyprus
(via sciencedaily.com) Original source The patterns of dispersal of early humans across continents and islands are hotly debated, but researchers have found that Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought. In examining the timing of the first human occupation of Cyprus, research found that large islands in the Mediterranean Sea were attractive and favorable destinations for palaeolithic peoples. These findings refute previous studies that suggested Mediterranean islands would have been unreachable and inhospitable for Pleistocene hunter-gatherer societies.
Published From roots to resilience: investigating the vital role of microbes in coastal plant health
(via sciencedaily.com) Original source Understanding how salt marsh grass stays healthy is of crucial ecological importance, and studying the ways bacteria interact with these plants is key. Thanks to recent advances in genomic technology, biologists have begun to reveal never-before-seen ecological processes.
Published Access to gardens and citizen science helps encourage conservation among children, study shows
(via sciencedaily.com) Original source Access to gardens and citizen science projects at school can help promote pro-conservation behaviour among pupils, a new study shows.
Published Summers warm up faster than winters, fossil shells from Antwerp show
(via sciencedaily.com) Original source In a warmer climate, summers warm much faster than winters, according to research into fossil shells. With this knowledge we can better map the consequences of current global warming in the North Sea area.
Published Climate change is most prominent threat to pollinators
(via sciencedaily.com) Original source A new article has found that climate change is the most prominent threat to pollinators -- such as bumblebees, wasps, and butterflies -- who are essential for biodiversity conservation, crop yields and food security. The research suggests that many of the threats to pollinators result from human activities.
