New research, just published in the journal Ringing & Migration, has used state of the art tracking technology to investigate how one of Britain’s largest ducks, the Shelduck, interacts with offshore wind turbines during their migration across the North Sea. Their findings reveal – for the first time – the length, speed and flight heights of this journey.

Symbionts are known to be an important aspect of almost every living organism. Invertebrates are no exception. They display a remarkable range of symbiotic relationships with bacteria, which are capable of altering reproduction, defence against natural enemies, and play a role in nutrition. Up until now, most work has centred on a bacteria called Wolbachia which is commonly found in insects.
Wolbachia is relatively rare in Odonates (dragonflies and damselflies) and other aquatic insects, but recent work has suggested the presence of another similarly pervasive microbe. Our work has revealed that the bacterium Rickettsia is carried in 40% of midge species, and the Azure Damselfly (Coenargrion puella) can carry one or two strains of infection. Data suggests that Rickettsia is a common but underrepresented feature of freshwater invertebrates and our aim is to see how true this theory is.
