Effects of floral restrictiveness and stigma size on heterospecific pollen receipt in a prairie community
Plant species vary greatly in the degree to which floral morphology restricts access to the flower interior. Restrictiveness of flower corollas may influence heterospecific pollen receipt, but theExpand
Asymmetrical conspecific seed-siring advantage between Silene latifolia and S. dioica.
BACKGROUND AND AIMS Silene dioica and S. latifolia experience only limited introgression despite overlapping flowering phenologies, geographical distributions, and some pollinator sharing.Expand
Pollinator behaviour, not increased resources, boosts seed set on forest edges in a New Zealand Loranthaceous mistletoe
Abstract The endemic New Zealand mistletoe Peraxilla tetrapetala (Loranthaceae) has previously been shown to be pollinator limited, and to experience higher fruit set in increasingly fragmentedExpand
Contrasting effects of plant invasion on pollination of two native species with similar morphologies
Invasive plants may decrease native plant density and disrupt interactions between native plants and their pollinators. We hypothesized that invasive Solidago canadensis (Asteraceae) competes forExpand
Do pollen carryover and pollinator constancy mitigate effects of competition for pollination
Pollinator constancy and pollen carryover are both thought to mitigate competitive effects that result when shared pollinators cause loss of pollen to heterospecific flowers. I present analytical andExpand
Pollinator limitation of seed set in Fuchsia perscandens (Onagraceae) on Banks Peninsula, South Island, New Zealand
Abstract Fuchsia perscandens, which has ornithophilous flowers, may be prone to pollinator limitation on the New Zealand mainland where pollinating birds are often scarce. To investigate thisExpand
Evidence for asymmetrical hybridization despite pre- and post-pollination reproductive barriers between two Silene species
Co-flowering species may undergo interspecific hybridization if they are closely related and share pollinators. However, a series of reproductive barriers between species can prevent interspecificExpand
Effect of introduced Euphorbia esula on the pollination of Viola pedatifida.
Introduced plants may compete for pollination with native plants, resulting in reduced fruit or seed set. In this study, I use several techniques to assess whether the invasive plant Euphorbia esulaExpand
Antipredatory Activity of the Weevil Oxyops vitiosa: A Biological Control Agent of Melaleuca quinquenervia
The larvae of the leaf-feeding weevil Oxyops vitiosa, a biological control agent of Melaleuca quinquenervia, are covered with a viscous orange coating that is thought to protect against generalistExpand
Pollination of Sisyrinchium campestre (Iridaceae) in Prairies Invaded by the Introduced Plant Euphorbia esula (Euphorbiaceae)
Abstract Introduced plants may compete for pollination with native species, leading to increased pollinator limitation for one or both species. In this study, I test the hypothesis that theExpand
