Fitness costs of delayed pollination in a mixed-mating plant [PDF]
, 2019 Background and Aims To predict the evolutionary consequences of pollinator declines, we need to understand the evolution of delayed autonomous self-pollination, which is expected to evolve as a mechanism of reproductive assurance when cross-pollination ...

Reproductive biology of two sympatric species of Polyalthia (annonaceae) in Sri Lanka. I. Pollination by curculionid beetles [PDF]
, 2006 The pollination biology of two sympatric species, Polyalthia coffeoides and Polyalthia korinti (Annonaceae), is described in detail. An Endaeus species (Coleoptera: Curculionidae) is shown to be the major pollinator of both species, with Carpophilus ...

Unlocking Kenya’s Pyrethrum Potential: A Breeding Review for a Competitive Future
Advances in Agriculture, Volume 2026, Issue 1, 2026.Pyrethrum (Tanacetum cinerariifolium) is a strategically important industrial crop underpinning the world supply of organic pesticides. Despite Kenya’s past dominance in global pyrethrum production, the genetic improvement of the crop has lagged. This has led to having varieties of low yields, variable pyrethrin content, susceptibility to biotic and ...

The island syndrome in plants on New Zealand's outlying islands: a review
New Zealand Journal of Botany, Volume 63, Issue 5, Page 2300-2324, December 2025.ABSTRACT The island syndrome is defined as a suite of predictable and consistent differences between island and mainland organisms. In seed plants, much of what we know about the island syndrome comes from work in the Southwest Pacific, which is comprised of the three main islands of New Zealand and ten surrounding archipelagos.

Reproductive aspects and flower visitors of Duguetia marcgraviana Mart. (Annonaceae) in the southwestern region of Mato Grosso [PDF]
Biotemas, 2010 The biology and flower visitors of Duguetia marcgraviana were studied in a forest fragment of the Municipality of Tangará da Serra – MT. The flowering phenology was monitored in eight adult plants and the numbers of flower buds and open flowers were ...

Evolutionary correlation of heterodichogamy and floral longevity
, 2016 Heterodichogamy, the coexistence of morphs differing in the time when the shift between male and female phases occurs, is a rare sexual dimorphism derived from synchronous dichogamy. In dichogamous populations, plants need to adjust the temporal sex role

Fruit ResearchAvocado (Persea americana) exhibits a distinctive flowering pattern known as diurnally synchronous protogynous dichogamy (DSPD), in which flowers of Type A cultivars open as female in the morning on day one and as male in the afternoon on day two, while ...

The temporal separation of gender in flowering plants: An evolutionary analysis
, 2003 Dichogamy, the temporal separation of gender within a flower, occurs in two forms: protandry, male function before female function, and protogyny, the converse.
