Published Whale remains tracked to highlight sustainable disposal benefits
(via sciencedaily.com) Original source A new study highlights the sustainable, cultural and ecosystem benefits of offshore removal or decomposition of whale remains. The study tracked the remains of a humpback whale that was intercepted before washing up on the shoreline, then repositioned 30km offshore and fitted with a satellite tag that tracked its position as it drifted with the wind and currents for 6 days before falling to the seabed.
Published Groundbreaking study reveals oceanic seabirds chase tropical cyclones
(via sciencedaily.com) Original source A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.
Published 'Sacrifice' of virus data clears the path to open a disease discovery pipeline
(via sciencedaily.com) Original source Tens of millions of still-unknown or misunderstood viruses can cause diseases -- including new pandemics -- and affect the health of valuable terrestrial and marine environments. Now a new pipeline to investigate the 'virosphere,' or all the genomes of viruses and bacteriophages (viruses that attack bacteria) of the world, has been developed by an international collaboration.
Published Study projects major changes in North Atlantic and Arctic marine ecosystems due to climate change
(via sciencedaily.com) Original source New research predicts significant shifts in marine fish communities in the North Atlantic and Arctic Oceans as a result of climate warming.
Published Restored oyster sanctuaries host more marine life
(via sciencedaily.com) Original source Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.
Published Coral reefs: Battlegrounds for survival in a changing climate
(via sciencedaily.com) Original source Coral reefs, those vibrant underwater cities, stand on the precipice of collapse. While rising ocean temperatures and coral bleaching grab headlines, a new essay reveals a hidden layer of complexity in this fight for survival: the often-overlooked roles of the reefs' smallest inhabitants.
Published Brain size riddle solved as humans exceed evolution trend
(via sciencedaily.com) Original source The largest animals do not have proportionally bigger brains -- with humans bucking this trend -- a new study has revealed.
Published Not so selfish after all: Viruses use freeloading genes as weapons
(via sciencedaily.com) Original source Certain pieces of DNA have been labeled as 'selfish genetic elements' due to notions that they don't contribute to a host organism's survival. Instead, researchers have now discovered that these elements have been weaponized and play a crucial role by cutting off a competitor's ability to reproduce.
Published Do genes-in-pieces code for proteins that fold in pieces?
(via sciencedaily.com) Original source A new study offers new insights into the evolution of foldable proteins.
Published Mighty floods of the Nile River during warmer and wetter climates
(via sciencedaily.com) Original source Global warming as well as recent droughts and floods threaten large populations along the Nile Valley. Sediment cores off the Nile mouth reveal insights into the effects and causes of heavy rainfall episodes about 9,000 years ago. That will help to prepare for weather extremes in a changing climate.
Published Giant clams may hold the answers to making solar energy more efficient
(via sciencedaily.com) Original source Solar panel and biorefinery designers could learn a thing or two from iridescent giant clams living near tropical coral reefs, according to a new study. This is because giant clams have precise geometries -- dynamic, vertical columns of photosynthetic receptors covered by a thin, light-scattering layer -- that may just make them the most efficient solar energy systems on Earth.
Published Near chromosome-level genome of the Mojave poppy bee
(via sciencedaily.com) Original source Scientists have developed a near chromosome-level genome for the Mojave poppy bee, a specialist pollinator of conservation concern.
Published Ocean acidification turns fish off coral reefs
(via sciencedaily.com) Original source A new study of coral reefs in Papua New Guinea shows ocean acidification simplifies coral structure, making crucial habitat less appealing to certain fish species.
Published AI-powered study explores under-studied female evolution
(via sciencedaily.com) Original source Pioneering AI-powered research on butterflies has probed the under-studied evolution of females and adds to a debate between Charles Darwin and Alfred Russel Wallace.
Published Researchers identify unique survival strategies adopted by fish in the world's warmest waters
(via sciencedaily.com) Original source A team of researchers have identified unexpected ways coral reef fish living in the warmest waters on earth, in the Arabian Gulf, have adapted to survive extreme temperatures.
Published Sixty-million-year-old grape seeds reveal how the death of the dinosaurs may have paved the way for grapes to spread
(via sciencedaily.com) Original source Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
Published Ecologists reconstruct the history of biodiversity in the Indo-Australian archipelago and its rise as a hotspot
(via sciencedaily.com) Original source The Coral Triangle, also known as the Indo-Australian Archipelago, is renowned for having the greatest marine biodiversity on our planet. Despite its importance, the detailed evolutionary history of this biodiversity hotspot has remained largely a mystery. An international research team has now shed light on this history, reconstructing how biodiversity in the region has developed over the past 40 million years.
Published Climate change to shift tropical rains northward
(via sciencedaily.com) Original source Atmospheric scientists predict that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator. The northward rain shift would be spurred by carbon emissions that influence the formation of the intertropical convergence zones that are essentially atmospheric engines that drive about a third of the world's precipitation.
Published Projected loss of brown macroalgae and seagrasses with global environmental change
(via sciencedaily.com) Original source Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role seaweeds and seagrasses in coastal ecosystems and provide evidence of the pervasive impacts of climate change on marine life.
Published Ammonites' fate sealed by meteor strike that wiped out dinosaurs
(via sciencedaily.com) Original source Ammonites were not in decline before their extinction, scientists have found.
