2019 Aug 15;7(1):coz048. Declines in bumble bee species in the past 60 years are well documented in Europe, where they are driven primarily by habitat loss and declines in floral abundance and diversity resulting from agricultural intensification. The western bumble bee (Bombus occidentalis occidentalis) has recently undergone a dramatic decline in abundance and distribution and is no longer present across much of … Most bumble bee species are currently not threatened or docu- mented as declining except in areas of intensive agriculture. In this study I discuss the importance of Natural History Collections Habitat is an integral component of any species and should be a central focus of conservation efforts to protect at risk species. Fewer flowers pollinated results in fewer viable seeds, reducing chances for future new individual plants. Declines in bumble bee species in the past 60 years are well documented in Europe, where they are driven primarily by habitat loss and declines in floral abundance and diversity resulting from agricultural intensification. Hence, populations are susceptible to stochastic extinction events and inbreeding. Suggested measures include tight regulation of commercial bumble bee use and targeted use of environmentally comparable schemes to enhance floristic diversity in agricultural landscapes. Planting flowers in your garden, or on your farm, is the best and easiest way to help conserve bumble bees. Eight spe- cies from three subgenera, however, have declined drastically during the last 15-20 years.  |  Science. (34). Figure 1: The push-pull strategy: diagrammatic representation of the components and generalized mode of action. Effects of invasive parasites on bumble bee declines. Hymenoptera , Bombus , rarity , population structure , habitat loss, With a growing world population and increasingly demanding consumers, the production of sufficient protein from livestock, poultry, and fish represents a serious challenge for the future. 2011 Aug;25(4):662-71. doi: 10.1111/j.1523-1739.2011.01707.x. Unfortunately, all indication, suggest bees are in decline based on assessments of specific groups of bees. Decline and Conservation of Bumble Bees Impacts of habitat degradation and fragmentation are likely to be compounded by the social nature of bumble bees and their largely monogamous breeding system, which renders their effective population size low. Impacts of habitat degradation and fragmentation are likely to be compounded by the social nature of bumble bees and their largely monogamous breeding system, … 2020 Oct 26;7(1):367. doi: 10.1038/s41597-020-00713-w.

Figure 4: Targeted genome editing in monarch butterflies.  |  These include three species that are obligate parasites on other declining species. Significant losses of managed honey bee colonies (Apis mellifera L.) have been reported annually around the world (Neumann and Carreck, 2010; Potts et al., 2010). As native bee populations decline, they pollinate fewer individual flowers. Evidence of a similar conservation dilemma in North America was largely anecdotal until 2008-2009 when declines were first quantified for bumble bee species in Illinois and Ontario, Canada. All three species have been assessed by the the Committee on the Status of Endangered Wildlife in … Half of the bumble bee species in a new study have seen a more than 50 percent decline in population and distribution.

Insect declines are being reported worldwide for flying, ground, and aquatic lineages.  |  In North America, catastrophic declines of some bumble bee species since the 1990s are probably attributable to the accidental introduction of a nonnative parasite from Europe, a result of global trade in domesticated bumble bee colonies used for pollination of greenhouse crops. It was last seen in 1999 and is listed as Endangered in Vermont. Today, it is much harder for kids to spot them, since bumble bees are drastically declining in North America and in Europe.

In the late 1990′s, bee biologists started to notice a decline in the abundance and distribution of several wild bumble bee species. Bumble bees have coevolved with many flowers; the bees are Declines have been attributed to many factors including habitat loss. The abundance and pollen foraging behaviour of bumble bees in relation to population size of whortleberry (Vaccinium uliginosum). To estimate changes in distribution and relative abundance I compare historic data assembled from a >73,000 specimen database with a contemporary 3-year survey of North American bumble bees across 382 locations in the contiguous U.S.A. Based on my results, four historically abundant bumble bees, B. affinis, B. occidentalis, B. pensylvanicus and B. terricola, have declined by 72 - 96% relative abundance … This bodes poorly for plant species that depend on them for pollination services. Most reports come from western and northern Europe, where the insect fauna is well-studied and there are considerable demographic data for many taxonomically disparate ...Read More.

High densities of honey bee colonies increase competition between native pollinators for forage, putting even more pressure on the wild species that are already in decline. NLM NIH Ninety-seven percent of ... temperatures and drier soil have led to a decline in alpine plant species (Kopp and Cleland, 2013). 2015 Dec;25(8):2119-31. doi: 10.1890/14-1748.1. The effect of intrinsic physiological traits on diapause survival and their underlying mechanisms in an annual bee species. Given the importance of bumble bees as pollinators of crops and wildflowers, steps must be taken to prevent further declines. Of these, three have already become extinct, eight are in serious decline and only six remain widespread. Mayer C, Michez D, Chyzy A, Brédat E, Jacquemart AL. Several reports of North American bumble bee (Bombus Latreille) decline have been documented across the continent, but no study has fully assessed the geographic scope of decline.
