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 ...
Alien plants and flower visitors disrupt the seasonal dynamics of mutualistic networks
(Wiley-Blackwell, 2020-01-13)
Alien species can drastically disrupt ecological processes such as those involving plant-pollinator interactions, performing central roles that may affect the structure of native pollination networks. However, most studies ...
Entomofauna visitante de Stenolobium stans (Juss.) Seem (Bignoniaceae), durante seu período de floração
(2001-12-01)
Studies on the different ways of reproduction of Stenolobium stans (Juss.) Seem and on the diversity, frequency and constancy of flower-visiting insects at different hours were carried out during four years. The S. stans ...
Frequency of visits by ants and their effectiveness as pollinators of Condalia microphylla Cav.
(Elsevier, 2014-06)
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 ...
Pollination of Adenocalymma bracteatum (Bignoniaceae): Floral Biology and Visitors
(Entomological Soc Brasil, 2010-11-01)
Adenocalymma bracteatum is a shrub of dense foliage and yellow flowers, easily found on grasslands areas in Central Brazil. The aim of this study was to determine the reproductive biology and the flower visitors of A. ...
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 ...
Bee Visitors of Quaresmeira Flowers (Tibouchina granulosa Cogn.) in the Region of Dourados (MS-Brasil)
(California State University, 2012-01-01)
This research was developed in the center-urban area at the city of Dourados (MS), in Tibouchina granulosa trees, a plant popularly known as quaresmeira in Brazil. The floral visitors of this species were recorded in three ...
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 ...
The functional roles of 3D heterostyly and floral visitors in the reproductive biology of Turnera subulata (Turneroideae: Passifloraceae)
(2020-03-01)
Heterostyly is a floral polymorphism that reduces conflicts between sexual functions (sexual interference), such as self-pollination in self-incompatible flowers and loss of pollen to incompatible stigmas. In many distylous ...
