Behavioural mechanisms underlying food-deceptive pollination and neonicotinoid exposure of bumblebees

Autor: Lämsä, J. (Juho)

Pollination is often used as a classic example of mutualism. However, not all plants produce any food reward for their pollinators. Such non-rewarding pollination strategies are called pollinator deception, as plants take advantage of innate and lear

Flies are important pollinators of mass-flowering caraway and respond to landscape and floral factors differently from honeybees

Autor: Mikko Kuussaari, Anna Elina Karimaa, Marjaana Toivonen, Irina Herzon

Non-bee insects have been identified as important crop pollinators globally. However, strategies to protect pollinators and enhance crop pollination usually focus on supporting bees. This study examined the effects of landscape structure, location wi

Geranium sylvaticum increases pollination probability by sexually dimorphic flowers

Autor: Soininen, Jaakko O. S., Kytöviita, Minna‐Maarit

Sexual dimorphism is expressed as different morphologies between the sexes of a species. Dimorphism is pronounced in gynodioecious populations which consist of female and hermaphrodite individuals. The small size of female flowers in gynodioecious sp

Linking pollinator occurrence in field margins to pollinator visitation to a mass-flowering crop

Autor: Mikko Kuussaari, Marjaana Toivonen, Jenni Toikkanen, Irina Herzon

Publikováno v: Journal of Pollination Ecology, Vol 28, Pp 153-166 (2021)

Uncultivated field margins are important refugia for pollinating insects in agricultural landscapes. However, the spill-over of pollination services from field margins to adjacent crops is poorly understood. This study (i) examined the effects of lan

A multilevel analysis on pollination-related policies

Autor: Simon G. Potts, Peter Sørensen, Tom D. Breeze, Outi Ratamäki, Pekka Jokinen

Publikováno v: Ratamati, O, Jokinen, P, Sørensen, P B, Breeze, T & Potts, S 2015, ' A multilevel analysis on pollination-related policies ', Ecosystem Services, vol. 14, pp. 133-143 . https://doi.org/10.1016/j.ecoser.2015.01.002

The paper explores pollination from a multilevel policy perspective and analyses the institutional fit and interplay of multi-faceted pollination-related policies. First, it asks what the major policies are that frame pollination at the EU level. Sec

Prolonged stigma and flower lifespan in females of the gynodioecious plant Geranium sylvaticum

Autor: Elzinga, Jelmer Anne, Varga, Sandra

In gynodioecious plants females need a reproductive advantage over hermaphrodites to be maintained in the same population. Generally, three main proximate causes for a female advantage are considered: inbreeding avoidance, different resource allocati
