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.
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 number of managed colonies in the United States for honey production has been in decline since the 1940s and these losses have increased since the early 2000s. Colony losses during winter are normal within beekeeping, however the rate of honeybee colony deaths, higher losses during the summer, as well as the inability to find a determinate ...
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 ...
With the decline of both wild and domestic pollinator populations, pollination management is becoming an increasingly important part of horticulture.Factors that cause the loss of pollinators include pesticide misuse, unprofitability of beekeeping for honey, rapid transfer of pests and diseases to new areas of the globe, urban/suburban development, changing crop patterns, clearcut logging ...

Globally declining bee populations threaten agricultural production and food security. [9] In the United States, beekeepers reported that they lost 45 percent of colonies in the year from April 2020 to April 2021. [4] Factors involved in population decline are complex and interrelated. [10] One of the areas Grozinger has studied is nutrition.
Monarch populations in the West face an even greater chance of extinction at 99% by the year 2080. The Fish and Wildlife Service is accepting public comments on its proposal until March 12, 2025.
