Florivory and sex ratio in Annona dioica St. Hil. (Annonaceae) in the Pantanal at Nhecolândia, southwestern Brazil Florivoria e razão sexual em Annona dioica St. Hil. (Annonaceae) no Pantanal da Nhecolândia, Brazil

Acta Botânica Brasílica, 2006
Annona dioica St. Hil. is a species that grows to approximately 2 m tall and is very widespread in the cerrados. Individual plants of this androdioecious species produce numerous hermaphroditic or male flowers, but few fruits.

Influence of Camponotus blandus (Formicinae) and flower buds on the occurrence of Parrhasius polibetes (Lepidoptera: Lycaenidae) in Banisteriopsis malifolia (Malpighiaceae)

Sociobiology, 2013
In the Brazilian savanna, myrmecophilous lycaenids are often found in many shrubs feeding on plant reproductive structures while are tended by ants, but only recently the role of both ants and food on the occurrence of lycaenids have received attention ...

Wasp florivory decreases reproductive success in an epiphytic bromeliad

Plant Ecology, 2008
Flower predation or florivory may alter the sexual expression, floral display, and reduce the reproductive success in plants. In this article, we estimated the effect of florivory on the reproductive success of the epiphytic bromeliad Werauhia gladioliflora during 2001-2003 in a premontane area in Costa Rica. Floral buds of W.

Management reduces floral damage by bees and beetles in Cereus jamacaru DC. (Cactaceae) in the Caatinga dry forest

Discover Plants
Florivory is the consumption of floral structures, affecting both developing flower buds and flowers, even those that have already been fertilized.

Floral Visitors and Florivory in Tacinga inamoena (Cactaceae) in the Ex Situ Collection of the Rio de Janeiro Botanical Garden

Journal of Zoological and Botanical Gardens
Tacinga inamoena (K. Schum.) N.P. Taylor & Stuppy (Cactaceae, Opuntioideae) is a native Brazilian species found in the Caatinga phytogeographic domain. Although its flowers are adapted for bird pollination (ornithophily), few birds visit these plants in ...

Misconceived experiments may yield valuable insights: Simulated florivory has unpredictable consequences for plant reproduction in Knautia arvensis (Caprifoliaceae)

Journal of Pollination Ecology
An experimental manipulation of ray florets in Knautia arvensis (Caprifoliaceae) carried out in 2001 originally yielded results that were hard to reconcile with a hypothesis about floral attraction.

Resilience of floral scent emission after florivory

Plant Biology
Abstract Throughout evolutionary time, florivory has always represented an important source of selective pressure on flower evolution. When feeding, florivores remove corolla portions and undoubtedly change floral visual traits; however, we are in the early stages of

How pollinator visits are affected by flower damage and ants presence in Ipomoea carnea subs. fistulosa (Martius and Choise) (Convolvulaceae)?

Brazilian Journal of Biology, 2019
This study aimed to evaluate the effects of florivory and of the patrolling ants associated to EFNs-extrafloral nectaries, on the frequency of floral visitors, using the specie Ipomoea carnea subs. fistulosa (Martius and Choise) in Caatinga area.
