Un estudio revela que los abejorros son sensibles al tráfico rodado

Un nuevo estudio de la Universidad de Lund muestra que el aumento del tráfico rodado conlleva una disminución de los nidos de abejorros en las cunetas. La investigación abarcó 60 emplazamientos en Escania.

El estudio, financiado por Trafikverket y publicado en Biological Conservation, examinó la relación entre el volumen de tráfico y la presencia de abejorros. La estudiante de doctorado Sofia Blomqvist señaló que, a lo largo de las carreteras con menor tráfico, casi no se encontraron abejorros muertos. En los tramos con unos 4000 vehículos diarios, se observaron más abejorros muertos que vivos durante los inventarios. Las cunetas ricas en flores a lo largo de las carreteras secundarias sirven como atractivos lugares de nidificación, mientras que no se hallaron nidos de abejorros en los tramos con un tráfico normal.

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.
