Radars that are used to report the weather also provide valuable insight into which migratory routes birds use. For the first time this tool will be used to map bird migration in Norway.

Nature does the job for us, for free.  But, in the search for good measures to compensate for man-made greenhouse gas emissions, carbon emissions from disturbance or loss of biodiversity caused by these measures are often not included in the calculation.

This study signals the need for fisheries management to account for ecosystem constraints when setting catch limits in periods of low forage fish biomass.

Using data from five different marine ecosystems, researchers have tested the hypothesis of predator‐pit dynamics for forage fish. By examining the consumption of fish by seabirds and the effect of such predation on fish population dynamics, they found that seabird-induced mortality of forage fish varies with fish abundance.
