To test if a single gene could affect an entire ecosystem, a research team conducted a lab experiment with a plant and its associated ecosystem of insects. They found that plants with a mutation at a specific gene foster ecosystems with more insect species. The discovery of such a ‘keystone gene’ […]

When naval ships and other sea vessels use sonar, many whale species flee for their lives; some even strand themselves on beaches in a desperate attempt to escape. Now, scientists have discovered the most likely reason: The loud sounds trigger the same fear response as when the animals hear calls emitted […]

Global temperatures are rising at an unprecedented rate, but environmental responses are often difficult to recognize and quantify. Long-term observations of plant phenology, the annually recurring sequence of plant developmental stages, can provide sensitive measures of climate change and important information for ecosystem […]

Social foraging, where animals forage in groups, takes many forms but is less studied in marine predators as measuring social associations in the wild is challenging. We used biologging (activity, cameras and telemetry receivers) sensors to measure social associations and simultaneous behaviour, in white sharks (Carcharodon carcharias) […]

Mice with sloppy proteinmaking machinery grow old faster, study finds. Cells are continually cranking out new proteins, but like car factories, they produce some lemons. A study of mice now suggests these defective proteins speed aging, bolstering an idea first proposed 60 years ago. The new paper “fills a critical gap” […]

It is vital to ramp up crop production dramatically by 2050 due to the increasing global population and demand for food. However, with the climate change projections showing that droughts and heatwaves becoming common in much of the globe, there is a severe threat of a sharp decline in crop yields. […]
