Two Bee-Pollinated Plant Species Show Higher Seed Production when Grown in Gardens Compared to Arable Farmland
BACKGROUND Insect pollinator abundance, in particular that of bees, has been shown to be high where there is a super-abundance of floral resources; for example in association with mass-flowering crops and also in gardens where flowering plants are often densely planted. Since land management affects pollinator numbers, it is also likely to affect the resultant pollination of plants growing in t...
متن کاملBumble Bee Abundance in New York City Community Gardens: Implications for Urban Agriculture
A variety of crops are grown in New York City community gardens. Although the production of many crops benefits from pollination by bees, little is known about bee abundance in urban community gardens or which crops are specifically dependent on bee pollination. In 2005, we compiled a list of crop plants grown within 19 community gardens in New York City and classified these plants according to...
متن کاملBreeding system and the role of floral visitors in seed production of a ‘few-flowered’ perennial herb, Paeonia broteroi Boiss. & Reut. (Paeoniaceae)
The breeding system and pollination ecology of Paeonia broteroi (Paeoniaceae), a selfcompatible, perennial herb, which produces few flowers (1-8) per season, are described in wo populations in mountains of southern Spain. Experimentally self-pollinated flowers yielded a significantly lower seed set (6-18%) than cross-pollinated flowers (23-29%), but the latter did not differ in seed set from op...
متن کاملEffective Population Size during Grass Germplasm Seed Regeneration.
Effective population size (N(e)) is the key parameter for predicting genetic drift associated with germplasm regeneration. A major factor reducing N(e) below the census population size (N(c)) is variation in seed production among plants in a given population. The objectives of this study were to estimate N(e)/N(c) associated with variation in seed production in three model wind pollinated, pere...
متن کاملBee diversity effects on pollination depend on functional complementarity and niche shifts.
Biodiversity is important for many ecosystem processes. Global declines in pollinator diversity and abundance have been recognized, raising concerns about a pollination crisis of crops and wild plants. However, experimental evidence for effects of pollinator species diversity on plant reproduction is extremely scarce. We established communities with 1-5 bee species to test how seed production o...
