Bicarpellate gynoecium in two species of Senna (Fabaceae, Caesalpinioidae, Cassiinae)

Acta Botânica Brasílica, 2016
Flowers of species of Senna are very morphologically diverse, however, nothing has been reported regarding variation in the presence of a unicarpellate gynoecium, which is characteristic of the group.

Sequential Florivory/Saproflorivory of Anaxagorea crassipetala (Annonaceae) by Diathoneura tessellata (Drosophilidae) [PDF]

Annals of the Entomological Society of America, 2009
Abstract Diathoneura tessellata Duda, 1925 (Diptera: Drosophilidae) uniquely and effectively uses the fleshy tepals of Anaxagorea crassipetala (Annonaceae), a small, understory tree of the primary lowland rain forest of Costa Rica, as a larval substrate and pupation site.

Anthophilous beetles ubiquitously inhabit night-blooming cacti but exhibit distinct responses to the spatial distribution of flowers [PDF]

Anais da Academia Brasileira de Ciências
Night-blooming cacti, primarily pollinated by bats and hawkmoths, also attract beetles seeking food and safe shelter for mating and brooding their offspring.

Do pollinators respond in a dose-dependent manner to flower herbivory?: An experimental assessment in Loasa tricolor (Loasaceae) ¿Responden los polinizadores en forma dosis-dependiente a la herbivoría floral?: Una evaluación experimental en Loasa tricolor (Loasaceae)

Gayana: Botanica, 2011
Pollinators are able to discriminate among different floral phenotypes. Thus, flowers more attractive to pollinators usually receive more visits to their reproductive structures.

Natural selection by pollinators on floral attractive and defensive traits did not translate into selection via fruits in common milkweed

Journal of Pollination Ecology
Considering both pollinator and herbivore pressures on plant reproductive and defensive traits is key to understanding patterns of selection for plants.

Experimental florivory and its effects on pollinators of Opuntia cantabrigiensis Lynch (Cactaceae)

Arthropod-Plant Interactions
Abstract Florivores modify the attributes of flowers while feeding, that affects the behavior and frequency of pollinators that visit flowers and setting of fruits and seed as a result of low pollen deposition. We determined the effect of experimental florivory on pollinators visitations, fruit-set, and seed-set of Opuntia cantabrigiensis ...

Florivory and pollinator visitation: a cautionary tale

Florivory and pollinator visitation: a cautionary tale
Florivory, or damage to flowers by herbivores, can make flowers less attractive to pollinators, potentially resulting in reduced plant fitness. However, not many studies have combined observations with experiments to assess the causal link between florivory and pollination. We conducted field observations at eight sites in northern California, combined
