Although the existence of pollinator decline can be difficult to determine, a number of possible reasons for the theoretical concept have been proposed, such as exposure to pathogens, parasites, and pesticides; habitat destruction; climate change; market forces; intra- and interspecific competition with native and invasive species; and genetic alterations.
The Africanized bee, also known as the Africanized honey bee (AHB) and colloquially as the "killer bee", is a hybrid of the western honey bee (Apis mellifera), produced originally by crossbreeding of the East African lowland honey bee (A. m. scutellata) with various European honey bee subspecies such as the Italian honey bee (A. m. ligustica) and the Iberian honey bee (A. m. iberiensis).
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]
Endangered (EN) species are considered to be facing a very high risk of extinction inside. In July 2017, the International Union for Conservation of Nature (IUCN) listed 343 endangered insect species. [1] Of all evaluated insect species, 5.7% are listed as endangered. The IUCN also lists 21 insect subspecies as endangered.
The population of this bumblebee species has decreased drastically since 1998, [2] with last sighting in Oregon, in 2006. [citation needed] Some experts, such as professor Dave Goulson at the University of Sussex, [8] say this species is already extinct, but until more concrete evidence is shown, it has been assigned a conservation status rank of G1 (critically imperiled) by NatureServe, [2 ...
A new study claims that the origin of bees is tens of millions of years older than previously believed. Actually, All Bees Come From an Ancient Supercontinent Called Gondwana Skip to main content
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
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 ...
