Floral resource availability of Dicliptera squarrosa (Acanthaceae) and its dependence on hummingbirds for fruit formation in a forest fragment of Central Brazil [PDF]

Plant Ecology and Evolution, 2019
Background and aims – Hummingbirds are dependent and specialized on nectar-feeding, and many plants depend upon them for pollination. However, the degree of plant-pollinator interdependence varies greatly among species; thus, information on plant mating ...

Floral Maturation and Insect Visitors of Pachyptera hymenaea (Bignoniaceae)

Biotropica, 1977
Flowers of the woody vine Pachyptera hymenaea change from dark lavender to light lavender or white in three days while retained on plants. By the time flowers are three days old, they do not contain pollen or nectar, but may attract pollinators to the plants. Thrips and weevils preyed upon reproductive parts of P. hymenaea.

Self-pollination rate and floral-display size in Asclepias syriaca (Common Milkweed) with regard to floral-visitor taxa [PDF]

BMC Evolutionary Biology, 2014
Animals fertilize thousands of angiosperm species whose floral-display sizes can significantly influence pollinator behavior and plant reproductive success. Many studies have measured the interactions among pollinator behavior, floral-display size, and plant reproductive success, but few studies have been able to separate the effects of pollinator ...

Notes on floral visitors in Seemannia sylvatica (Kunth) Hanstein (Gesneriaceae)

Revista Peruana de Biología, 2012
Pollination in Gesneriaceae commonly is associated with syndromes of ornithophily or melittophily, and usually others visitors are robbers of nectar. We present a note about the fauna that visit the flowers of Seemannia sylvatica in Cusco, where hummingbirds and insects were recorded visiting the flowers. Based on floral characteristics and behavior of

Potential pollinators and robbers: a study of the floral visitors of Heliconia angusta (Heliconiaceae) and their behaviour

Journal of Pollination Ecology, 2011
Floral syndromes are traditionally thought to be associated with particular pollinator groups. Ornithophilous flowers tend to have traits that facilitate bird pollination such as having long, narrow, tubular corollas, often vivid coloration and diluted ...

The impacts of biological invasions

Biological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

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 ...

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

Ecography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Queer configurations: The female divine, regional identity, and Queer‐religious belonging in South India

Feminist Anthropology, EarlyView.
Abstract This article explores how queerness and religion intersect in a unique enactment of Bathukamma, a flower festival honoring the female divine in Hyderabad, the capital of the South Indian state of Telangana. Drawing on theories of figuration, I analyze how local queer organizations celebrate the festival in a way that engages two distinctive ...
