Exploitation of floral resources on Sparattosperma leucanthum (Bignoniaceae): foraging activity of the pollinators and the nectar and pollen thieves
(Springer Heidelberg, 2012-04-01)
The interaction between floral visitors and plants in natural ecosystems has become a major subject in studies on biodiversity conservation. However, there is a very complex interaction between the community of floral ...
Frequency of visits by ants and their effectiveness as pollinators of Condalia microphylla Cav.
The effect of a pollinator species on a plant depends on their interaction frequency and the pollinator's effectiveness. The role of ants as pollinators is highly variable, in some cases they act as true pollinators and ...
Weak trophic links between a crab-spider and the effective pollinators of a rewardless orchid
(Elsevier Masson, 2015-01)
Sit and wait predators hunting on flowers are considered to be exploiters of plantepollinator mutualisms. Several studies have shown that plantepollinator interactions can be highly susceptible to the impact of a third ...
Triple interaction network among flowers, flower visitors and crab spiders in a grassland ecosystem
(Taylor & Francis, 2013-12)
This study presents the first description of a tri-trophic interaction network with crab spiders as predators. Monthly observations of flowering entomophilous plant species were recorded between December 2009 and March ...
Pollen content accumulated in nests of Polybia scutellaris (Hymenoptera, Vespidae)
(Taylor & Francis, 2010)
Plant resources foraged by Polybia scutellaris were identified by analysing the pollen content of 14 nests in Magdalena (Buenos Aires Province, Argentina). Six nests were inhabited at the time of collection. The palynological ...
