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.
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]
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%.
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 seeing a population decline of about 80%. The service announced a proposal to list the butterfly ...
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.
A "bee invasion" halted play on a court at the BNP Paribas Open tennis tournament in California on Thursday, and video showed the insects swarming over a camera lens and buzzing around players.
More commonly insect conservation occurs indirectly, either through the setting aside of large portions of land using "wilderness preservation" as the motive, or through protection of "charismatic vertebrates". Some studies estimate that global insect populations are in rapid decline, perhaps by as much as 80% in recent decades.
