Contrasting styles in cognition and behaviour in bumblebees and honeybees.
Bumblebees and honeybees have been the subjects of a great deal of recent research in animal cognition. Many of the major topics in cognition, including memory, attention, concept learning, numerosity, spatial cognition, timing, social learning, and metacognition have been examined in bumblebees, honeybees, or both. Although bumblebees and honeybees are very closely related, they also differ in...
متن کاملSimple Models for Exploitative and Interference Competition
Jensen, A.L., 1987. Simple models for exploitative and interference competition. Ecol. Modelling, 35: 113-121. Competition is exploitative when species compete for the same limited resource, and interference when species deplete one another's resources by interferences such as aggressive displays or fighting. If pure exploitative competition is defined as an effect on the carrying capacity, and...
متن کاملExploitative competition between invasive herbivores benefits a native host plant.
Although biological invasions are of considerable concern to ecologists, relatively little attention has been paid to the potential for and consequences of indirect interactions between invasive species. Such interactions are generally thought to enhance invasives' spread and impact (i.e., the "invasional meltdown" hypothesis); however, exotic species might also act indirectly to slow the sprea...
متن کاملVisual attention in a complex search task differs between honeybees and bumblebees.
Mechanisms of spatial attention are used when the amount of gathered information exceeds processing capacity. Such mechanisms have been proposed in bees, but have not yet been experimentally demonstrated. We provide evidence that selective attention influences the foraging performance of two social bee species, the honeybee Apis mellifera and the bumblebee Bombus terrestris. Visual search tasks...
متن کاملRelationship Between Pollination Behavior of Invasive Honeybees and Native Bumblebees in Montane Meadows
Data on plant-pollinator interactions collected over six summers in montane meadows of the HJ Andrews Experimental Forest provided an opportunity to explore the association between two genera of generalist pollinators: Apis and Bombus. Ten plots in each meadow were “watched” for fifteen minutes five times every summer, and each flower species in a meadow-watch was assigned a class based on the ...
