  1. Forests and streams are separate but linked ecosystems, existing side by side, with energy and nutrients crossing their porous borders and flowing back and forth between them. For example, leaves fall from trees, enter streams, decay and feed aquatic insects. Those insects emerge from the waters and are eaten by birds and bats. An international team has now found that these ecosystems appear to keep the energy exchanges in balance -- a finding that the scientists called surprising.View the full article
  2. Biologists have published a chromosomally assembled reference genome for the European brown hare. The genome consists of 2.9 billion base pairs, which form 23 autosomal chromosomes, and X and Y sex chromosomes. The timing of the genome release is very appropriate as the brown hare also represents the original Easter Bunny familiar from European folklore.View the full article
  3. A curious aspect of tree frogs is that they often lay their eggs on the ground where the risk of predation by natural enemies is greater than in the trees where they live. A research team suggested that the reason for this behavior is to protect the eggs from low temperatures. Their findings highlight the challenge faced by tree frogs: Should they attempt to maintain an optimal temperature for their eggs or risk predation?View the full article
  4. Researchers believe a group of killer whales observed hunting marine mammals including sperm whales, as well as a sea turtle, in the open ocean off California and Oregon could be a new population. Based on available evidence, the researchers posit that the 49 orcas could belong to a subpopulation of transient killer whales or a unique oceanic population found in waters off the coast of California and Oregon.View the full article
  5. Scientists have confirmed that a potentially fatal dog parasite is present in a portion of the Colorado River that runs through California.View the full article
  6. We expect tropical animals to handle a certain degree of heat, but not wild swings in temperature. That seems to be true for tropical ectotherms, or 'cold-blooded' animals such as amphibians, reptiles, and insects. However, in a new study of 'warm-blooded' endotherms, a research team found tropical birds can handle thermal variation just fine.View the full article
  7. Imported giant sequoia trees are well adapted to the UK, growing at rates close to their native ranges and capturing large amounts of carbon during their long lives, finds a new study.View the full article
  8. 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.View the full article
  9. 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.View the full article
  10. 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.View the full article
  11. 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.View the full article
  12. 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.View the full article
  13. 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.View the full article
  14. Invasive plants can stay dormant for decades or even centuries before rapidly expanding and wreaking ecological havoc, finds a new study.View the full article
  15. Scientists found unexpected evidence the area of polynyas around Antarctica is increasing dramatically, and it follows an intriguing cycle, growing and shrinking roughly every 16 years.View the full article
  16. 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.View the full article
  17. 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.View the full article
  18. 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.View the full article
  19. 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.View the full article
  20. Scientists uncover the intricate dance between drought, wildfires and invasive species in Southern California's coastal sage scrub ecosystems.View the full article
  21. 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.View the full article
  22. 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.View the full article
  23. The effects of a phenomenon called tree masting on ecosystems and food webs can be better understood thanks to new theoretical models validated by real world observations.View the full article
  24. Every day, new areas of rainforests are converted into plantations, drastically changing tropical biodiversity and the way the ecosystem functions. Yet, the current understanding of the consequences is fragmentary: previous studies tended to examine either biodiversity or the ecosystem. An international research team brings these threads together in this study. They analyzed organisms ranging from microscopic mites and earthworms in the soil, to beetles and birds in tree canopies, comparing tropical rainforest with rubber and oil palm plantations in Sumatra, Indonesia.View the full article
  25. Deep-water corals in the Gulf of Mexico are still struggling to recover from the devastating Deepwater Horizon oil spill in 2010, scientists report at the Ocean Science Meeting in New Orleans. Comparing images of more than 300 corals over 13 years -- the longest time series of deep-sea corals to date -- reveals that in some areas, coral health continues to decline to this day.View the full article
