Visualising multiple stressors on European river catchments : the MARS Scenario Analysis Tool [The Freshwater Blog]

Over the last four years, the MARS project has been investigating the interactions and impacts of multiple stressors on Europe’s aquatic ecosystems. This is a topic at the cutting edge of freshwater science research, and MARS scientists have sought to understand how the multiple pressures humans place on the environment – nutrient pollution, habitat alteration, climate change, water abstraction, and many more – act together to cause stress on the continent’s rivers and lakes. As a result, this work is important for environmental managers and policy makers seeking effective options to mitigate multiple stresses, and conserve or restore Europe’s freshwaters.

Termite queen, king recognition pheromone identified [Phys]

A study published in Proceedings of the National Academy of Sciences shows that a wax-like hydrocarbon—a chemical consisting of only carbon and hydrogen atoms called heneicosane—on the body surface of subterranean royal termites is used to enable worker termites to recognize and care for them. Termites live mostly underground or in wood and are generally blind, necessitating the use of chemical signals to communicate.
