متن کاملPredator-prey coevolution: Australian native bees avoid their spider predators.
Australian crab spiders Thomisus spectabilis manipulate visual flower signals to lure introduced Apis mellifera. We gave Australian native bees, Austroplebia australis, the choice between two white daisies, Chrysanthemum frutescens, one of them occupied by a crab spider. The colour contrast between flowers and spiders affected the behaviour of native bees. Native bees approached spider-occupied...
متن کاملCrab spiders (Araneae: Thomisidae) in flowering plants in a Brazilian "Cerrado" ecosystem.
Although crab spiders are common in flowering plants, their relations with plant species and its floral traits have been poorly known in the Neotropics. Observations regarding plant habits, floral visitors and also floral characteristics such as anthesis, odour, shape, colour and floral resources were recorded in flowering plant species of an area of "Cerrado" on a 2 km long trail. Misumenops a...
متن کاملIsland hopping across the central Pacific: mitochondrial DNA detects sequential colonization of the Austral Islands by crab spiders (Araneae: Thomisidae)
Aim Phylogenetic studies concerning island biogeography have been concentrated in a fraction of the numerous hot-spot archipelagos contained within the Pacific Ocean. In this study we investigate relationships among island populations of the thomisid spiderMisumenops rapaensis Berland, 1934 across the Austral Islands, a remote and rarely examined southern Pacific hot-spot archipelago. We also a...
متن کاملRelationship between colouration and body condition in a crab spider that lures pollinators.
Sit-and-wait predators have evolved several traits that increase the probability of encountering prey, including lures that attract prey. Although most crab spiders (Thomisidae) are known by their ability to change colour in order to match the background, a few use a different strategy. They are UV-reflective, creating a colour contrast against UV-absorbing flowers that is attractive for pollin...
