Published Exploring arctic plants and lichens: An important conservation baseline for Nunavut's newest and largest territorial park
(via sciencedaily.com) Original source A comprehensive study of the floristic diversity of Agguttinni Territorial Park, Nunavut's newest and largest Territorial Park, has documented 141 vascular plant, 69 bryophyte, and 93 lichen species from this unique protected area on northern Baffin Island. Through a combination of extensive fieldwork in 2021 and examination of hundreds of existing herbarium specimens, the authors have documented species newly reported for Baffin Island and have crafted a biodiversity baseline important for park management and conservation.
Published Rice paddy snake diversification was driven by geological and environmental factors in Thailand, molecular data suggests
(via sciencedaily.com) Original source A new study of rice paddy snakes in Southeast Asia gives key details to their diversification and natural history, adding molecular evidence that the rise of the Khorat Plateau and subsequent environmental shifts in Thailand may have altered the course of the snakes' evolution some 2.5 million years ago.
Published Rainforest's next generation of trees threatened 30 years after logging
(via sciencedaily.com) Original source Rainforest seedlings are more likely to survive in natural forests than in places where logging has happened -- even if tree restoration projects have taken place, new research shows.
Published Mapping the future's sweet spot for clean energy and biodiversity
(via sciencedaily.com) Original source A new study of Joshua trees, kit foxes and solar energy developments highlights the need to consider climate-induced range shifts for species as we expand clean energy.
Published Reptile roadkill reveals new threat to endangered lizard species
(via sciencedaily.com) Original source The chance sighting of a dead snake beside a sandy track in remote Western Australia, and the investigation of its stomach contents, has led researchers to record the first known instance of a spotted mulga snake consuming a pygmy spiny-tailed skink, raising concerns for a similar-looking, endangered lizard species.
Published Herbivores, displaced by ocean warming, threaten subtropical seagrass meadows
(via sciencedaily.com) Original source The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.
Published Invasive plant time bombs: A hidden ecological threat
(via sciencedaily.com) Original source Invasive plants can stay dormant for decades or even centuries before rapidly expanding and wreaking ecological havoc, finds a new study.
Published Modeling the origins of life: New evidence for an 'RNA World'
(via sciencedaily.com) Original source Scientists provide fresh insights on the origins of life, presenting compelling evidence supporting the 'RNA World' hypothesis. The study unveils an RNA enzyme that can make accurate copies of other functional RNA strands, while also allowing new variants of the molecule to emerge over time. These remarkable capabilities suggest the earliest forms of evolution may have occurred on a molecular scale in RNA, and also bring scientists one step closer to re-creating autonomous RNA-based life in the laboratory.
Published An evolutionary mystery 125 million years in the making
(via sciencedaily.com) Original source Plant biologists have uncovered an evolutionary mystery over 100 million years in the making. It turns out that sometime during the last 125 million years, tomatoes and Arabidopsis thaliana plants experienced an extreme genetic makeover. Just what happened remains unclear. But the mystery surrounds CLV3, a gene key to healthy plant growth and development.
Published In wake of powerful cyclone, remarkable recovery of Pacific island's forests
(via sciencedaily.com) Original source After one of the most intense cyclones in world history tore through the Pacific island of Tanna in Vanuatu, new research showed the resilience of the island's forests.
Published Scientists ID burned bodies using technique used for extracting DNA from woolly mammoths, Neanderthals
(via sciencedaily.com) Original source A technique originally devised to extract DNA from woolly mammoths and other ancient archaeological specimens can be used to potentially identify badly burned human remains, according to research.
Published Genetic research revealed several new fern species in tropical America
(via sciencedaily.com) Original source Researchers have clarified the evolutionary history of a previously poorly known group of ferns from the tropical rainforests of America using DNA methods. The study discovered many new fern species, 18 of which have now been given official names and species descriptions.
Published Bottlenecks and beehives: How an invasive bee colony defied genetic expectations
(via sciencedaily.com) Original source An invasive Asian honeybee colony in northern Australia has defied expectations, displaying emergent genetic variation in a short period of time. While bad news for biosecurity agencies, it could be a sign that species under pressure from climate change can be resilient.
Published Climate change threatens thousands of archaeological sites in coastal Georgia
(via sciencedaily.com) Original source Thousands of historic and archaeological sites in Georgia are at risk from tropical storm surges, and that number will increase with climate change, according to a new study.
Published Study finds drought fuels invasive species after wildfires
(via sciencedaily.com) Original source Scientists uncover the intricate dance between drought, wildfires and invasive species in Southern California's coastal sage scrub ecosystems.
Published Experiment captures why pottery forms are culturally distinct
(via sciencedaily.com) Original source Potters of different cultural backgrounds learn new types differently, producing cultural differences even in the absence of differential cultural evolution. The research has implications for how we evaluate the difference of archaeological artifacts across cultures.
Published Birds and bee lessons as Pacific field trips also solve 'Michener's mystery'
(via sciencedaily.com) Original source Eight new Pacific bee species and new insights into Fijian bird behaviour on Viti Levu Island have been described in new scientific studies. The research highlights the potential for species discovery, ecological and conservation knowledge and cultural engagement from Asia-Pacific research collaborations.
Published Plant seed and fruit analysis from the biblical home of Goliath sheds unprecedented light on Philistine ritual practices
(via sciencedaily.com) Original source While many aspects of Philistine culture are well-documented, the specifics of Philistine religious practices and deities have long remained shrouded in mystery. A recent study contributes valuable new data to our understanding of the Philistine's ritual practices. The discovery of numerous plants in two temples unearthed at the site unraveled unprecedented insights into Philistine cultic rituals and beliefs -- their temple food ingredients, timing of ceremonies, and plants for temple decoration.
Published Mice surprise: Researchers discover new native species
(via sciencedaily.com) Original source Australia can lay claim to two new species of native rodent thanks to a new study. The aptly named delicate mouse was previously thought to be a single species spanning a massive stretch of the country from the Pilbara in Western Australia, across parts of the Northern Territory and through Queensland down to the New South Wales border. We now know there are three distinct species.
Published Biggest Holocene volcano eruption found by seabed survey
(via sciencedaily.com) Original source A detailed survey of the volcanic underwater deposits around the Kikai caldera in Japan clarified the deposition mechanisms as well as the event's magnitude. As a result, the research team found that the event 7,300 years ago was the largest volcanic eruption in the Holocene by far.
