When plant pollen scarce, bumblebees biting leaves causes flowers to bloom early

A new study reveals that bumblebees bite leaves of flowerless plants to accelerate flowering, causing blooms to occur two weeks to a month earlier. This behavior suggests that bumblebees can manipulate plant flowering through deliberate damage, providing pollination systems with more plasticity and resilience to climate change.

Towable sensor free-falls to measure vertical slices of ocean conditions

Researchers at MIT and WHOI have developed a lightweight instrument that can measure both physical and biological features of the ocean's vertical layers. The EcoCTD uses a combination of sensors to capture data on temperature, salinity, and chlorophyll content, providing insights into nutrient cycles and carbon sequestration.

Peculiar behavior of the beetle Toramus larvae

The larvae of beetle genus Toramus attach their exuviae to the distal abdomen and retain them throughout development. This unique behavior may serve as a form of autotomy, allowing predators to remove exuviae without harming the larva. However, further studies are needed to confirm its defensive function.
