Bluesky ekspanderer vildsomt, men de blå sommerfugle forsvinder fra Danmark. Her ændringer i % i udbredelse fra 1990 til 2020. Kun skovblåfugl er i fremgang; den kan godt lide haver og parker. Almindelig er stadig almindelig, men alle de andre... 😢 [DEL gerne] #dknatur #biodiversitet

Der er meget lobbyisme for træplantning ifm den grønne #trepart - jeg minder om at #træer i stor stil fremspirer af sig selv de fleste steder i DK & at selvgroet #skov har mange fordele, ikke mindst for #biodiversitet og #mennesker - og er langt billigere🌱#dkpol #dkgreen PS: Selvsået eg i min have🌳

Check out how we are using high speed cameras to study how and why some bees use vibrations to shake flowers and extract their pollen. Here is our latest work. www.cell.com/current-biol...
Buzz-pollinating bees deliver thoracic vibrations to flowers through periodic biting
Woodrow et al. show that buzz-pollinating bees transmit thoracic vibrations to flowers
via the head during a periodic anther biting behavior. This is facilitated by a flexible
mechanism in the neck. T...
