Animal-mediated pollination is essential for both ecosystem services and conservation of global biodiversity, but a growing body of work reveals that it is negatively affected by anthropogenic disturbance. Landscape-scale disturbance results in two often inter-related processes: (1) habitat loss, (2) disruptions of habitat configuration (i.e. fragmentation). Understanding the relative effects o...

PREMISE OF THE STUDY Changes in the pollinator communities of marginal plant populations can affect their pollination quantity or quality. Geographic variation in pollination success can alter the reproductive advantage that female plants require to persist within gynodioecious populations. Particularly valuable is determining the pollination success at the prezygotic stage in self-compatible g...

Highbush blueberry yields are dependent on pollination by bees, and introduction of managed honey bees is the primary strategy used for pollination of this crop. Complementary pollination services are also provided by wild bees, yet highbush blueberry is increasingly grown in regions outside its native range where wild bee communities may be less adapted to the crop and growers may still be tes...

Thermopsis turcica Kit Tan, Vural & Kucukoduk (Fabaceae) is a rare and endemic Turkish species grown around Aksehir Lake and Eber Lake of the southern areas of Central Anatolia. T. turcica has a gynoecium of 2-4 functional carpels. This characteristic of T. turcica is unique in the subfamily Papilioideae of Fabaceae. Although this genotype is valuable as female plants, to date there is no consi...

Pollinator abundance is declining worldwide and may lower the quantity and quality of pollination services to flowering plant populations. Loss of an important pollinator is often assumed to reduce the amount of pollen received by stigmas of a focal species (pollination success), yet this assumption has rarely been tested experimentally. The magnitude of the effect, if any, may depend on the re...

• Understanding how pollination affects plant reproductive success and how changes in pollination service affect plant populations, communities and ecosystems is of increasing concern. Yet supplemental hand-pollination traditionally used to assess pollen limitation is prohibitive for large-scale comparative work. Moreover, it does not differentiate between quality and quantity aspects of pollen...

18 yield 19 20 21 22 Citizen science and pollination services 2 Abstract 23 1) Pollination by insects is a vital ecosystem service and the need for its 24 assessment is increasing in recognition and political pressure, but there are 25 currently no large-scale systematic monitoring schemes in place to measure 26 the direct provision of this service. 27 2) This study tested a protocol for using ...

Pollination is an ecosystem service that is essential to support the production of a wide range of crops. The service is increasingly under threat, as a consequence of among others habitat loss of pollinators and increasing use of pesticides. In order to support maintaining the pollination service in agriculture, there is a need to better understand the economic value generated by the pollinati...

Pollination by sexual deception is arguably one of the most unusual liaisons linking plants and insects, and perhaps the most illustrative example of extreme floral specialization in angiosperms. While considerable progress has been made in understanding the floral traits involved in sexual deception, less is known about how this remarkable mimicry system might have arisen, the role of pre-adap...
