It has been debated whether pollination success in nonrewarding plants that flower in association with nectar-producing plants will be diminished by competition for pollinator visits or, alternatively, enhanced through increased local abundance of pollinators (the magnet species effect). We experimentally evaluated these effects using the nonrewarding bumblebee-pollinated orchid Anacamptis morio and associated nectar-producing plants at a site in Sweden. Pollination success (estimated as pollen receipt and pollen removal) in A. morio was significantly greater for individuals translocated to patches of nectar-producing plants (Geum rivale and Allium schoenoprasum) than for individuals placed outside (∼20 m away) such patches. These results provide support for the existence of a facilitative magnet species effect in the interaction between certain nectar plants and A. morio. To determine the spatial scale of these interactions, we correlated the visitation rate to flowers of A. morio with the density of sym...

Positive interactions among plant species for pollinator service: assessing the 'magnet species' concept with invasive species (2008, background): “For instance, Laverty (1992) showed that both pollinator visitation rate and seed output of Podophyllum peltatum increases when grow close to the magnet species Pedicularis canadensis. More recently, Moeller (2004) showed that both inter and intraspecific interactions of co-occurring Clarkia spp. th”
ECOLOGICAL CONTEXT OF THE EVOLUTION OF SELF-POLLINATION IN CLARKIA XANTIANA: POPULATION SIZE, PLANT COMMUNITIES, AND REPRODUCTIVE ASSURANCE (2005, background): “However, interactions can be facilitative when coexisting plant species jointly attract or maintain pollinator populations (Johnson et al. 2003; Moeller 2004).”
Facilitative interactions among plants via shared pollinators (2004, background): “…for positive interactions (Macior 1971, Brown and Kodric-Brown 1979, Waser and Real 1979, Thomson 1981, Rathcke 1983), but evidence remains limited to systems where plant species providing no pollinator rewards benefit from close proximity to rewarding species (Laverty 1992, Johnson et al. 2003).”
INTERSPECIFIC NEIGHBORS CHANGE SEED DISPERSAL PATTERN OF AN AVIAN-DISPERSED PLANT (2005, background): “…facilitation could be caused by a ‘‘magnet’’ effect of preferred or more rewarding plant species over less preferred species (Thomson 1978, Johnson et al. 2003), by nutritional complementarity (Whelan et al. 1998), or it could arise as an artifact of staggered phenology patterns of…”
The outcome of shared pollination services is affected by the density and spatial pattern of an attractive neighbour (2014, background): “The extent of the positive effect depends on a close spatial association between the species (e.g. Laverty 1992; Johnson et al. 2003; Molina-Montenegro, Badano & Cavieres 2008).”
Floral diversity and the facilitation of pollination (2006, background): “…(i.e. pollinators are generalists but tend to show preferences to particular floral types), then pollination of rare, or less rewarding, species may be enhanced by the increased attraction of pollinators to highly rewarding ‘magnet’ species with which they occur (Laverty 1992; Johnson et al .”
Interactions between hawkmoths and flowering plants in East Africa: polyphagy and evolutionary specialization in an ecological context (2013, background): “The African flora appears to be particularly rich in moth-pollinated plant taxa (Johnson & Nilsson, 1999; Luyt & Johnson, 2001; Johnson et al., 2003; Anderson, Alexandersson & Johnson, 2010).”
Insect pollinators collect pollen from wind‐pollinated plants: implications for pollination ecology and sustainable agriculture (2018, background): “…plant species and these interactions are a key driver of plant community structure (e.g. Robertson, 1895; Mosquin, 1971; Heinrich, 1975; Waser, 1978; 2017 The Royal Entomological Society, Insect Conservation and Diversity, 11, 13–31 Johnson et al., 2003; Moeller, 2004; L azaro et al., 2009).”

Interspecific Pollen Transfer: Magnitude, Prevalence and Consequences for Plant Fitness (2008, background): “…species consistently increased the deposition of conspecific pollen, the focal plant was a rewardless orchid (Anacamptis morio), whose flowers lack rewards (pollen or nectar) for visiting insects, and therefore benefits from sharing pollinators with rewarding neighbors (Johnson et al., 2003).”
