Studie belegt Empfindlichkeit von Hummeln gegenüber Straßenverkehr

Eine neue Studie der Universität Lund zeigt, dass ein erhöhtes Verkehrsaufkommen zu weniger Hummelnestern an Straßenrändern führt. Die Untersuchung umfasste 60 Standorte in Schonen.

Die von Trafikverket finanzierte und in Biological Conservation veröffentlichte Studie untersuchte den Zusammenhang zwischen Verkehrsaufkommen und dem Vorkommen von Hummeln. Doktorandin Sofia Blomqvist stellte fest, dass an den am wenigsten befahrenen Straßen so gut wie keine toten Hummeln gefunden wurden. Bei einem Verkehrsaufkommen von etwa 4.000 Fahrzeugen pro Tag wurden bei den Bestandsaufnahmen mehr tote als lebende Hummeln beobachtet. Blumenreiche Straßenränder an kleineren Wegen dienen als attraktive Nistplätze, während an Strecken mit normalem Verkehrsaufkommen keine Hummelnester gefunden wurden.

Five people were taken to hospital after a major pile-up on the E22 in Blekinge near Sölvesborg on Monday. Strong winds blew sand that suddenly reduced visibility for drivers, according to witnesses. The road was closed in both directions for several hours.

Buff-tailed bumblebees have demonstrated an ability to recognize rhythmic patterns, surprising scientists who thought it required a large brain. Researchers trained the insects to distinguish sequences of flashing lights and vibrations, akin to Morse code. The findings suggest even small-brained animals can process abstract rhythms.

Scientists at Cornell University have uncovered a massive population of ground-nesting miner bees at East Lawn Cemetery in Ithaca, New York, one of the largest known communities worldwide. The site supports between 3 million and 8 million bees, highlighting cemeteries as vital habitats for pollinators amid urban pressures. Researchers emphasize the role of these solitary bees in pollinating local crops like apple trees.
