A study by Tohoku University and Yamagata University found that the habitats of five of the six bumblebee species, which play a major role in pollination of agricultural crops and wild plants, are shrinking due to the effects of climate change.An analysis of the data from the Hanamaru Bumblebee Census conducted with the participation of citizens.
According to Yamagata University, the survey included Assistant Professor Yukari Ohno of the Graduate School of Life Sciences, Tohoku University, and Professor Jun Yokoyama, an academic researcher at Yamagata University.Since there was no domestic distribution data for bumblebees, the current and past distributions were estimated from the data collected in the "Hanamaru Bumblebee Census", a citizen-participation survey.
As a result, of the six main species of bumblebees that inhabit the country, five species, the bumblebee, the bumblebee, the bumblebee, the bumblebee, the bumblebee, the bumblebee, and the bumblebee, are shrinking their habitat due to the effects of climate change. I found out.
The tiger bumblebee was also affected by the local increase in forest area.The research group suspects that in a dense coniferous forest, the light does not reach the floor and the number of flowers has decreased.The distribution of Bombus terrestris and Bombus terrestris was significantly reduced in Hokkaido.On the contrary, the bumblebee expanded its habitat due to the rise in temperature.
