Wild bee pollinators provide the majority of crop visitation across land‐use gradients in New Jersey and Pennsylvania, USA (2007, background): “…lycopersicum L., Greenleaf & Kremen 2006a); blueberry ( Vaccinium spp., Cane 1997); sunflower ( Helianthus annuus L., Greenleaf & Kremen 2006b); canola ( Brassica spp., Morandin & Winston 2005), providing a supplement to honeybee pollination as well as an insurance policy against honeybee declines.”
Relationships between wild bees, hoverflies and pollination success in apple orchards with different landscape contexts (2016, background): “Maintaining diverse communities, however, requires appropriate orchard management practices (Morandin & Winston, 2005; Gabriel et al., 2010), as well as a heterogeneous landscape structure with a certain amount of semi-natural habitat in the surroundings to provide suitable foraging and nesting…”
Insect pollinated plants benefit from organic farming (2007, background): “…organic farming on the abundance and species richness of arable weeds and pollinators have been reported (Menalled et al., 2001; Hyvönen et al., 2003; Morandin and Winston, 2005; Roschewitz et al., 2005; Gabriel et al., in press; A. Holzschuh, personal communication; but see Weibull et al., 2000).”
Quantifying the impacts of bioenergy crops on pollinating insect abundance and diversity: a field‐scale evaluation reveals taxon‐specific responses (2013, background): “This could be explained by abundant nectar and pollen production by this crop, on which both groups of bees forage (Morandin & Winston 2005; Holzschuh et al. 2011), and by the noncrop floral resources, which were also more abundant in oilseed rape fields.”
Abundance and diversity of wild bees along gradients of heavy metal pollution (2012, background): “Many plant species that are directly dependent on insect pollination for fruit and seed production (Wilkaniec, Giejdasz & Prószyński 2004; Morandin & Winston 2005; Velthuis & van Door 2006) might experience *Correspondence authors.”
Plant biodiversity enhances bees and other insect pollinators in agroecosystems. A review (2012, unknown): “Harvesting and transport costs may increase slightly with greater yields, but this is not included in the analysis (Morandin and Winston 2005).”
Synthesis, part of a Special Feature on A Social-Ecological Analysis of Diversified Farming Systems: Benefits, Costs, Obstacles, and Enabling Policy Frameworks Ecosystem Services in Biologically Diversified versus Conventional Farming Systems: Benefits, Externalities, and Trade-Offs (2012, background): “…an experimental study revealed that seed set was on average 3 to 6 times lower on conventional and GMO canola fields using insecticides and herbicides than on organic fields, and this reduced seed set was strongly correlated with reduced abundances of native pollinators (Morandin and Winston 2005).”
Safeguarding pollinators and their values to human well-being (2016, unknown): “In one case lower bee abundance in herbicide-tolerant fields led to an oilseed rape pollination deficit 59 .”
Where is the value in valuing pollination ecosystem services to agriculture (2015, background): “All such forecasts fail to consider that current oilseed production may very well be produced under conditions of pollination deficit (Morandin and Winston, 2005).”
Stability of pollination services decreases with isolation from natural areas despite honey bee visits. (2011, background): “…Brassica napus and juncea A. mellifera, Syrphidae, native bees No, yes 33 Dry woodland 50–216 Australia, New South Wales 11, 4–43 transects No data Canola (B) Morandin & Winston 2005* Brassica napus Many wild bees, including species of Andrena, Halictus, and Bombus No, no < 2 Aspen woodland,…”
Bee declines driven by combined stress from parasites, pesticides, and lack of flowers (2015, background): “Herbicides are highly effective at minimizing weed problems in most cropping systems, enabling farmers to grow near-pure monocultures, but their use inevitably reduces the availability of flowers for pollinators and can contribute substantially to rendering farmland an inhospitable environment for b”
Importance of pollinators in changing landscapes for world crops (2007, background): “…canola and oilseed rape) comparison of organic, conventional and genetically modified (GM) fields number of seeds per silique from a flower sample Morandin & Winston (2005) proportional area of uncultivated land around fields within a 750 m radius number of seeds per silique from a flower…”
Pollination reservoirs for wild bee habitat enhancement in cropping systems: a review (2017, background): “Results of some studies suggest that wild bee abundance impacts crop pollination services (Morandin and Winston 2005), but bee species richness often emerges as the key factor.”
