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]
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
As of July 2016, the International Union for Conservation of Nature (IUCN) lists 58 extinct species, 46 possibly extinct species, and one Extinct in the wild species of insect. [ 1 ] [ 2 ] Caddisflies
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
Monarch populations in the West face an even greater chance of extinction at 99% by the year 2080. The Fish and Wildlife Service is accepting public comments on its proposal until March 12, 2025.
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus Bombus, part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., Calyptapis) are known from fossils.
