Supporting crop pollinators with floral resources: network-based phenological matching
The production of diverse and affordable agricultural crop species depends on pollination services provided by bees. Indeed, the proportion of pollinator-dependent crops is increasing globally. Agriculture relies heavily on the domesticated honeybee; the services provided by this single species are under threat and becoming increasingly costly. Importantly, the free pollination services provide...
متن کاملFloral Temperature and Optimal Foraging: Is Heat a Feasible Floral Reward for Pollinators?
As well as nutritional rewards, some plants also reward ectothermic pollinators with warmth. Bumble bees have some control over their temperature, but have been shown to forage at warmer flowers when given a choice, suggesting that there is some advantage to them of foraging at warm flowers (such as reducing the energy required to raise their body to flight temperature before leaving the flower...
متن کاملFloral advertisement scent in a changing plant-pollinators market
Plant-pollinator systems may be considered as biological markets in which pollinators choose between different flowers that advertise their nectar/pollen rewards. Although expected to play a major role in structuring plant-pollinator interactions, community-wide patterns of flower scent signals remain largely unexplored. Here we show for the first time that scent advertisement is higher in plan...
متن کاملFloral evolution as a figment of the imagination of pollinators.
Schaefer and Ruxton recently reviewed the mechanisms involved in plant deception, with an emphasis on pollination [1]. They proposed that generalised food deception evolves if plants exploit the innate preferences of pollinators, and thus represents a form of exploitation of perceptual biases (EPB). They contrast this with floral mimicry, which is viewed as a distinct phenomenon that might orig...
متن کاملInsect pollinators in corn and soybean agricultural fields
Iowa’s landscape is dominated by row crop agriculture with the majority of acres being in corn and soybean production, and as a result is spatially uniform and functionally homogenized. In landscapes dominated by agriculture, such as those found in Iowa, the availability of mass flowering crop species show strong positive effects on the density of generalist, native pollinators. While soybean, ...
