Pollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems worldwide that began being recorded at the end of the 20th century. Multiple lines of evidence exist for the reduction of wild pollinator populations at the regional level, especially within Europe and North America.
They have been found from the Mediterranean California all the way up to the Tundra regions of Alaska, making them one of the bees with the widest range geographic range. [4] However, recently there has been a noticeable decline in population. [5] In the past decade, the population of B. occidentalis has dropped by around 40.32%.
Honey bees at a hive entrance: one is about to land and another is fanning. Colony collapse disorder (CCD) is an abnormal phenomenon that occurs when the majority of worker bees in a honey bee colony disappear, leaving behind a queen, plenty of food, and a few nurse bees to care for the remaining immature bees. [1]
The decline was "apparent regardless of habitat type" and could not be explained by "changes in weather, land use, and habitat characteristics". The authors suggested that not only butterflies, moths and wild bees appear to be in decline, as previous studies indicated, but "the flying insect community as a whole". [1] [4] [52] [53] [54]
Starting in 2006, California almond growers began to suffer losses due to colony collapse disorder, a poorly understood phenomenon resulting in the decline of bee populations. [2] While this increased pollination expenses for many growers, high demand for almonds created an incentive to transport bees from across the United States to California.
Honey bees are incredibly social insects. They live together in big groups with other bees in an organized society that scientists call eusocial, which means every bee has a job to do. This could ...
The winged insects fall into the order Hymenoptera, which includes bees and ants. Wasps come in a variety of colors — from yellow and black to red and blue — and are split into two primary ...
The U.S. Fish and Wildlife Service is pushing for added protections for the monarch butterfly after suggesting multiple populations could go extinct in mere decades.
