“…Indeed, research has indicated that generalist bees are more common foraging on invasive alien plants than specialists (LopezaraizaMikel et al, 2007;Tepedino et al, 2008). Although concern has been expressed over the loss of specialist bee taxa (Biesmeijer et al, 2006;Fitzpatrick et al, 2007), the loss of generalist bees could be far more detrimental to plant communities (Memmott et al, 2004).…”

“…Many invasive alien plants are visited (Valentine, 1978;Butz Huryn and Moller, 1995 Stout et al, 2006;Totland et al, 2006;Lopezaraiza-Mikel et al, 2007;Bartomeus et al, 2008a;Tepedino et al, 2008) and pollinated (Parker, 1997;Richardson et al, 2000;Stout, 2007) by native bees. These plants are attractive to native bees for many reasons: some produce a massive floral display, have prolific nectar production, and often appear at high density or dominate the flower community in invaded sites (Ghazoul, 2002;Bjerknes et al, 2007).…”

Ecological impacts of invasive alien species on bees

-We review direct and indirect impacts of invasive alien species (focussing on plants and insects) on native bees worldwide. Although there is a rapidly growing body of research into the effects of invasive alien plants on native plant pollination via disruption of native mutualisms, there has been little research on the impacts of invasive alien plants directly on bees. Such impacts are likely to vary according to the taxon of plant, the functional specificity of the native bees, and ecosystem context. Conversely, there have been more attempts to document impacts of invasive alien social bees on native bees. Most of these studies only indirectly evaluate competition for resources, have focused on a few native species and findings are sometimes contradictory. However, some studies showed strong negative impacts, suggesting that effects might be species-specific. Additionally, pathogen spillover and reproductive disruption due to interspecific mating has been demonstrated among some closely related taxa. Where we lack unequivocal evidence for impacts however, this should not be interpreted as lack of effect. We recommend that future studies are robustly designed and consider impacts on genetic, species (particularly solitary bees) and ecosystem biodiversity.Apis mellifera / Bombus / non-native species / pollinator / plant invasion

“…It is important to note that some previous work (Fiedler et al 2012) on invasive species removal in prairie restoration had no effect on bee diversity, which quickly rebounded after removal of glossy buckthorn, Frangula alnus L. However, this result may not translate to the removal of all invasive species if they provide vital resources to bee species (Roulston and Goodell 2011). Many invasive species can be beneficial to bees (Tepedino et al 2008), and removal of them could hurt conservation efforts unless adequate nutritional replacements are quickly restored. Given that many of the species that managers identified were legumes, which tend to offer high quality pollen (Weiner et al 2010) and can be very attractive to bees, habitat losses in the TGP of these invasive species may be of particular concern for bee conservation.…”

“…This sustained stocking rate is commonly termed carrying capacity [6,7] and is used as a metric to balance ecological, economic, and aesthetic concerns [8][9][10][11]. In practice, carrying capacity is rarely measured [12] and initial estimates are progressively adjusted in adaptive management programs.…”

Elk Island National Park in western Canada provides an ideal case study for an economic carrying capacity estimate because it supports high density of four species of ungulates (11/km 2 ), lacks large predators, and is enclosed by a 2.1-meter mesh fence. This high density of ungulates has created persistent management challenges by altering vegetation structure and community composition. Using linear programming, we explored optimal allocation of forage resources for bison (Bison bison bison), moose (Alces andersoni), wapiti (Cervus elaphus manitobensis) and deer (Odocoileus virginianus and O. hemionus) to maximize ungulate biomass and numbers, when constrained by use of the major forage classes and minimum viable populations (MVP) of those ungulate species that do not cross the boundary fence (bison and wapiti). Maximum numbers of animals were achieved by a stocking combination dominated by deer and bison, whereas maximum biomass was attained when bison and moose were abundant but deer were absent. Wapiti remained at MVP during all solutions. Optimal solutions consistent with current ungulate densities were associated with 7 to 11% forage removal. This is less than normally assumed for sustainable forage use, and may reflect the need to account for other biotic and abiotic losses to forage in carrying capacity models for which ungulate densities can be constrained by availability of a preferred forage class (e.g., grass) as well as forage quality. This research extends the conventional animal-unit concept to multispecies systems and provides templates based on forage biomass allocation for resource managers facing similar problems of joint stocking in different environments.
