Pollination Ecology of Sabatia Campenstris Nutt. (Gentianaceae)

Nectary tracks as pollinator manipulators: The pollination ecology of Swertia bimaculata (Gentianaceae)

Floral nectaries are closely associated with biotic pollination, and the nectar produced by corolla nectaries is generally enclosed in floral structures. Although some Swertia spp. (Gentianaceae), including S. bimaculata, evolved a peculiar form of corolla nectaries (known as "gland patches") arranged in a conspicuous ring on the rotate corolla and that completely expose their nectar, little is...

Pollen limitation and reproduction varies with population size in experimental populations of Sabatia angularis (Gentianaceae)

Individuals in large plant populations are expected to benefit from increased reproductive success relative to those in small populations because of the facilitative effects of large aggregations on pollination. As populations become small, the inability to attract sufficient numbers of pollinators can reduce reproduction via pollen limitation. This study experimentally tested whether such tren...

Evolutionary Ecology of Pollination and Reproduction of Tropical Plants

Pollination ecology of four epiphytic orchids of New Zealand.

BACKGROUND AND AIMS In New Zealand epiphytic orchids are represented by four genera and eight species. The genera Earina (three species) and Winika (one species) are the most conspicuous and widespread. These are likely to be some of the southernmost distributed genera of epiphytic orchids in the world. METHODS To identify the pollination strategies that have evolved in these orchids, hand-po...
