Weddell seals, which are excellent divers, during lactation provide so much iron to their pups that the mothers then dramatically limit their own diving and underwater foraging capabilities.
Nutrition solution can help heat-stressed cows as US warms
Rising temperatures pose major challenges to the dairy industry -- a Holstein's milk production can decline 30 to 70% in warm weather -- but a new study has found a nutrition-based solution to restore milk production during heat-stress events, while also pinpointing the cause of the decline.
Less Rain in the Forest: Amazon Even More Vulnerable Than Previously Thought
For every three trees dying from drought in the Amazon rainforest, a fourth tree – even though not directly affected – will die, too.
HKU Marine Scientists Unveil Sea Urchin’s Secret to Surviving Marine Heatwaves
Global ocean temperatures are increasing due to climate change, exposing ecosystems to extreme temperatures called marine heatwaves (MHWs), which can increase the temperature of marine waters by 5°C higher than normal in summer.
The Global Map of Aridity
Precipitation alone does not properly characterize vegetation water stresses.
New study calculates retreat of glacier edges in Alaska’s Kenai Fjords National Park
As glaciers worldwide retreat due to climate change, managers of national parks need to know what's on the horizon to prepare for the future. A new study has measured 38 years of change for glaciers in Kenai Fjords National Park south of Anchorage and discovered that 13 of the 19...
Ragweed allergy: Aggressiveness of pollen is determined by its place of origin and by the environment
The different geographic and climatic regions from which ragweed pollen originates, as well as the degree of environmental pollution, may influence the severity of allergic reactions such as hay fever and asthma. Pollen from plants in different areas exhibit different levels of aggressiveness.
The value of seagrass to the planet’s future is far greater than appreciated
Experts at the forefront of efforts to restore the UK's coastal seagrass meadows say the remarkable plant's contribution to the UN Sustainable Development goals deserves to be reassessed. Conserving and restoring seagrass meadows actually contributes to achieving 16 out of the 17 goals.
Single-cell approaches and deep learning to map all stages of fruit fly embryo development
Using the fruit fly, scientists have constructed a complete and detailed single-cell map of embryo development. This research will also help scientists pursue questions like how mutations lead to different developmental defects and provides a path to understand the vast non-coding part of our genome that contains most disease-associated mutations.
NASA Data on Plant ‘Sweating’ Could Help Predict Wildfire Severity
A new study uses data from the ECOSTRESS instrument aboard the space station to better understand why some parts of a wildfire burn more intensely than others.
