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]
Declining numbers of bees predate CCD by several decades, however: the US managed hive industry has been shrinking at a steady pace since 1961. [13] In contrast, the bee population worldwide has been increasing steadily since 1975, based on honey production, with China responsible for most of the growth. [14]
Winter said bee populations are on the decline due to rising threats from pests and threats to their nutrition and habitat. Winter told CNN that humans have put bee habitats in jeopardy with ...
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.
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 ...
