Floral allocation at different altitudes in highly autogamous alpine Chaetanthera euphrasioides (Asteraceae) in the central Chilean Andes
(Swiss Botanical Society, 2012-11-20)
In the alpine life-zone, increasingly slower and
unpredictable pollination at the higher altitudes predict an
increase in floral investment in strongly outcrossing, pollenlimited
biotically pollinated plant species, but ...
Influence of Apis mellifera L. (Hymenoptera: Apidae) on the Use of the Most Abundant and Attractive Floral Resources in a Plant Community
(Entomological Soc Brasil, 2013-12-01)
Some factors influence the distribution of abundance of floral visitors, especially the amount and quality of the floral resources available, the size of the area occupied by the visitor, habitat heterogeneity, and the ...
Cumulative individual seed production in the polycarpic Caesalpinia gilliesii (Fabaceae): effects of temporal variability in floral display, plant density and pollination
(The Society of Plant Reproductive Biologists, 2016-01)
In polycarpic species, floral display size and density of conspecific neighbours are time variable as well as their effects on pollination and fecundity. Here, we address how individual pollinator-dependent seed production ...
The floral structure of three weedy species of Sida (Malvaceae)
(2014-01-01)
Malvaceae sensu lato is monophyletic and is characterized by the presence of nectaries of glandular trichomes, located internally at the base of the calyx. The genus Sida has been heterogeneous since its origin; however, ...
Sexual dimorphism and gynoecium size variation in the andromonoecious shrub Caesalpinia gilliesii
(Wiley Blackwell Publishing, Inc, 2005-03)
The degree of sexual dimorphism in flowers and inflorescences can be evaluated early in flower development through the study of floral organ size co-variation. In the present work, the gynoecium-androecium size relationship ...
Partilha de polinizadores por espécies quiropterófilas em um fragmento de Cerrado, São Paulo
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2010-06-29)
Flowering plants need some external pollen vectors to accomplish sexual reproduction. For plants, the access of sexual mates by pollinators agents is a limiting factor, wich make pollen vectors a critical resource for ...
Refuse attracts? Effect of refuse dumps of leaf-cutting ants on floral traits
(Wiley Blackwell Publishing, Inc, 2019-02-13)
The nutrient-rich organic waste generated by ants may affect plant reproductive success directly by enhancing fruit production but also indirectly, by affecting floral traits related with pollinator attraction. Understanding ...
Factors affecting pollinator movement and plant fitness in a specialized pollination system
(2011)
The rate of pollen exchange within and among flowers may depend on pollinator attraction traits such as floral display size and flowering plant density. Variations in these traits may influence pollinator movements, pollen ...

(Facultad de Ciencias Naturales. Universidad de Guayaquil, 2023)
El estudio de la Biología Floral del mangle rojo (Rhizophora mangle L.) Reserva Ecológica Manglares Churute, Provincia del Guayas, Ecuador, tiene por objetivo analizar la biología floral de esa especie, describiendo sus ...
A reduced, yet functional, nectary disk integrates a complex system of floral nectar secretion in the genus Zeyheria (Bignoniaceae)
(Soc Botanica Brasil, 2017-07-01)
The genus Zeyheria (Bignoniaceae) comprises only two species, both of which have been described as possessing a reduced and non-functional nectary disk. Despite the importance of this evolutionary change in the floral ...
