Clever males prevail - but is it down to the choice of females or their own cleverness? A recent study shows that intelligent males of the mosquitofish (Gambusia holbrooki) have a better chance of mating. However, it remains unclear whether this is due to females preferring smarter males or whether the latter are more skilful in asserting themselves.

The Federal Bureau of Maritime Casualty Investigation (BSU; german: Bundesstelle für Seeunfalluntersuchung) is the central authority for investigating marine casualties in German territorial waters and on German-flagged ships worldwide. It also takes action when German nationals are injured at sea - regardless of the flag under which the ship concerned is sailing.
An unexpected result: zoologist Ralph Schill updates the tardigrade checklist: Tardigrades are tiny, resilient and amazingly adaptable - but their biodiversity in Germany has long been poorly researched.
