Published Caribbean parrots thought to be endemic are actually relicts of millennial-scale extinction
(via sciencedaily.com) Original source For the first time, researchers have extracted ancient DNA from Caribbean parrot fossils and archaeological specimens, showing that species thought to be endemic to particular islands were historically more widespread and diverse.
Published New research reveals extreme heat likely to wipe out humans and mammals in the distant future
(via sciencedaily.com) Original source A new study shows unprecedented heat is likely to lead to the next mass extinction, akin to when the dinosaurs died out, eliminating nearly all mammals in some 250 million years time.
Published Study shows birds that have evolved greater complexity are less biodiverse
(via sciencedaily.com) Original source Research shows that birds with more complex skeletons are more specialized and so are less species rich.
Published Drug discovery on an unprecedented scale
(via sciencedaily.com) Boosting virtual screening with machine learning allowed for a 10-fold time reduction in the processing of 1.56 billion drug-like molecules. Researchers teamed up with industry and supercomputers to carry out one of the world's largest virtual drug screens.
Published Greenwashing a threat to a 'nature positive' world
(via sciencedaily.com) Original source Researchers have identified the threat greenwashing poses to a 'nature positive' world, one where environmental decline halts and biodiversity outcomes improve.
Published Understanding the sex life of coral gives hope of clawing it back from the path to extinction
(via sciencedaily.com) Original source Scientists have mapped the reproductive strategies and life cycle of an endangered coral species, the purple cauliflower soft coral Dendronephthya australis. Lab-grown larvae have been successfully introduced back into the wild.
Published Let it flow: Recreating water flow for virtual reality
(via sciencedaily.com) A research team has harnessed the power of deep reinforcement learning to replicate the flow of water when disturbed. The replication allowed for recreating water flow in real time based on only a small amount of data, opening up the possibility for virtual reality interactions involving water.
Published Slow growth in crocodile ancestors pre-dated their semi-aquatic lifestyle
(via sciencedaily.com) Original source A groundbreaking study is reshaping our understanding of crocodile evolution by pinpointing the onset of slow growth rates to the Late Triassic period, much earlier than the previously assumed Early Jurassic timeline. The research highlights newly discovered fossil crocodile ancestors (known as crocodylomorphs) that exhibited slow growth rates, similar to modern-day crocodilians. Intriguingly, these early crocodylomorphs were not the lethargic, semi-aquatic creatures we are familiar with today; they were small, active, and fully terrestrial. The study also suggests that this slow-growth strategy was not a mere evolutionary quirk but a survival mechanism, as only the slow-growing crocodylomorphs managed to survive the End-Triassic mass extinction. This stands in stark contrast to the fast-growing dinosaurs of the same era, setting the stage for the divergent evolutionary paths that would later define their modern descendants.
Published Researchers issue urgent call to save the world's largest flower -Rafflesia -- from extinction
(via sciencedaily.com) Original source A new study finds that most Rafflesia species, which produce the world's largest flowers, face extinction. Lack of protection at local, national, and international levels means that remaining populations are under critical threat.
Published Researchers discover a new species of larger benthic foraminifer from the Ryukyu Islands
(via sciencedaily.com) Original source An international group of researchers have discovered a previously unknown species of large foraminifer, shedding new light on the ecological evolution and biodiversity of coral reefs in the Ryukyu Islands.
Published Assessing unintended consequences in AI-based neurosurgical training
(via sciencedaily.com) A new study shows that human instruction is still necessary to detect and compensate for unintended, and sometimes negative, changes in neurosurgeon behavior after virtual reality AI training. This finding has implications for other fields of training.
Published RNA for the first time recovered from an extinct species
(via sciencedaily.com) Original source A new study shows the isolation and sequencing of more than a century-old RNA molecules from a Tasmanian tiger specimen preserved at room temperature in a museum collection. This resulted in the reconstruction of skin and skeletal muscle transcriptomes from an extinct species for the first time. The researchers note that their findings have relevant implications for international efforts to resurrect extinct species, including both the Tasmanian tiger and the woolly mammoth, as well as for studying pandemic RNA viruses.
Published The pace of climate-driven extinction is accelerating
(via sciencedaily.com) Original source Studying a lizard species in Arizona mountains, researchers found 70 years' worth of climate-related extinction occurred in only seven years.
Published Almost half of koala habitats will be under high bushfire threat by 2070
(via sciencedaily.com) The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.
Published Study shows replanting logged forests with diverse mixtures of seedlings accelerates restoration
(via sciencedaily.com) • Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.
Published Protected nature reserves alone are insufficient for reversing biodiversity loss
(via sciencedaily.com) Original source Protected nature areas are considered fundamental for maintaining biodiversity and countering its loss. But how effectively do established protected areas work and prevent negative trends? Research shows mixed effects of protected areas on various species.
Published Freshwater connectivity can transport environmental DNA through the landscape
(via sciencedaily.com) A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.
Published Nature's great survivors: Flowering plants survived the mass extinction that killed the dinosaurs
(via sciencedaily.com) Original source A new study by researchers from the University of Bath (UK) and Universidad Nacional Autónoma de México (Mexico) shows that flowering plants escaped relatively unscathed from the mass extinction that killed the dinosaurs 66 million years ago. Whilst they suffered some species loss, the devastating event helped flowering plants become the dominant type of plant today.
Published Invasive alien species play key role in 60% of global plant and animal extinctions
(via sciencedaily.com) A new report presents major findings on the gravity of impacts from invasive alien species on our planet.
Published Echoes of extinctions: Novel method unearths disruptions in mammal trait-environment relationships
(via sciencedaily.com) Original source New research explores the historical shifts in mammal traits and biodiversity loss in eastern Africa. The study reveals how environmental changes disrupted mammal communities and highlights the urgent need for targeted conservation efforts to protect vulnerable species.
