Crab spiders affect flower visitation by bees
In a field experiment, the bumblebee, B. ternarius, visited milkweed patches harboring crab spiders, Misumena atia, at a lower frequency than patches free of crab spiders, and honeybees showed a similar but non-significant trend. Two other bumblebee species, B. terricola and B. agans, did not avoid the spider patches. The latter two species are larger than B. ternarius and honeybees and suffer ...
متن کاملThe Role of Morphology in Diet and Flower Visitation by Five Species of Cuban Flower-Visiting Bats
Pollinator and flower morphology are important factors in structuring the plant-pollinator relationship. A pollinator’s morphology may influence aspects of its diet. Flower-visiting bats are important pollinators but very little is known about what influences their interactions with food plants. I examined the role of morphology in the partitioning of food resources for five species of flower-v...
متن کاملEocene fossil is earliest evidence of flower-visiting by birds.
Birds are important pollinators, but the evolutionary history of ornithophily (bird pollination) is poorly known. Here, we report a skeleton of the avian taxon Pumiliornis from the middle Eocene of Messel in Germany with preserved stomach contents containing numerous pollen grains of an eudicotyledonous angiosperm. The skeletal morphology of Pumiliornis is in agreement with this bird having bee...

متن کاملBirds and people in Europe.
At a regional scale, species richness and human population size are frequently positively correlated across space. Such patterns may arise because both species richness and human density increase with energy availability. If the species-energy relationship is generated through the 'more individuals' hypothesis, then the prediction is that areas with high human densities will also support greate...
