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]
Extirpated from the wild in the early 1970s and reintroduced in 1998. [30] Texas red wolf: Canis rufus rufus: Central Texas to southern Louisiana Extinct in the wild by 1980 and introduced (in lieu of the extinct subspecies) to eastern North Carolina in 1987. The species is threatened by human persecution and hybridization with coyotes. [31]
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.

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.
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 ...
Located about 2,300 miles (3,680 km) from the nearest continental shore, the Hawaiian Islands are the most isolated group of islands on the planet. The plant and animal life of the Hawaiian archipelago is the result of early, very infrequent colonizations of arriving species and the slow evolution of those species—in isolation from the rest of the world's flora and fauna—over a period of ...
