A dead carpenter bee. 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.
Story at a glance New research underscores the negative effect of climate change on alpine bee populations. According to 60 years’ worth of data, bees in alpine regions are in an evolutionary ...
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]
Bees pollinate a third of the food we eat, and 80 percent of the world’s flowers. Honeybee populations worldwide have declined almost 40 percent according to one recent survey. Jim and Karen ...
Scientists have been sounding the alarm about the decline in beneficial insect populations for years. Studies show that many species of bees, butterflies, and other pollinators are in serious trouble.
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.

The study delved into the impacts of climate change on honey bee colony dynamics, particularly focusing on the Pacific Northwest. Warmer autumns, winters pose threat to PNW honey bee survival, WSU ...
Bee pollination is important both ecologically and commercially, and the decline in wild bees has increased the value of pollination by commercially managed hives of honey bees. The analysis of 353 wild bee and hoverfly species across Britain from 1980 to 2013 found the insects have been lost from a quarter of the places they inhabited in 1980.
