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.
A decline in bee population leads to a decline in crop yield, which will then result in a reduction in the food supply and cause economic hardships for farmers. [24] [25] Commercially produced B. impatiens is one of the most important species of pollinator bees that are used by greenhouse industry in North America, [7] including Canada and ...
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]
This series explores aspects of America that may soon be just a memory -- some to be missed, some gladly left behind. From the least impactful to the most, here are 25 bits of vanishing America ...
Bombus affinis, commonly known as the rusty patched bumble bee, is a species of bumblebee endemic to North America. [3] Its historical range in North America has been throughout the east and upper Midwest of the United States, [4] north to Ontario, Canada, where it is considered a "species at risk", [5] east to Quebec, south to Georgia, and west to the Dakotas. [5]
A decline in bumblebee numbers could cause large-scale changes to the countryside, resulting from inadequate pollination of certain plants. [123] Some bumblebees native to North America are also vanishing, such as Bombus balteatus, [124] Bombus terricola, [125] Bombus affinis, [126] [127] and Bombus occidentalis; one, Bombus franklini, may be ...
Honey bee starvation is a problem for bees and beekeepers.Starvation may be caused by unfavorable weather, disease, long distance transportation or depleting food reserve. Over-harvesting of honey (and the lack of supplemental feeding) is the foremost cause for scarcity as bees are not left with enough of a honey store, though weather, disease, and disturbance can also cause problem
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 ...
