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 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]
Perdita meconis, the Mojave poppy bee, is a rare bee species that was described in 1993. [2] The Mojave poppy bee has been petitioned for protection under the Endangered Species Act due to pressures in their native range such as invasive species, habitat fragmentation, gypsum mining, and climate change.
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).
Despite the world's last captive thylacine dying in 1936, the secretive animal wasn't declared extinct until 1986. More recently in 2007 the Baiji dolphin , a rare river dolphin native to China ...
Many endemic organisms have very specific requirements for their survival that can only be found within a certain ecosystem, resulting in their extinction. Extinction may also take place very long after the destruction of habitat, a phenomenon known as extinction debt. Habitat destruction can also decrease the range of certain organism populations.
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
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 ...
