Abstract: Abstract Premise Hybridization between cross‐compatible species depends on the extent of competition between alternative mates. Even if stigmatic compatibility allows for hybridization, hybridization requires the heterospecific pollen to be competitive. Here, we determined whether conspecific… read more here.

Abstract: PREMISE Those co-flowering species that have not evolved an avoidance mechanism may exhibit tolerance to heterospecific pollen (HP) deposition as an adaptive strategy to minimize any deleterious effects of HP transfer, but empirical evidence for… read more here.

DOI: 10.1002/ajb2.1865
Abstract: PREMISE OF THE STUDY Pollinator sharing of co-flowering plants may result in interspecific pollen receipt with a fitness cost. However, the underlying factors determining the effects of heterospecific pollen (HP) are not fully understood. Moreover,… read more here.

DOI: 10.1002/ece3.9795
Abstract: Abstract Generalized pollinators visit multiple co‐flowering plant species and may transfer heterospecific pollen grains. Recent studies have indicated that the effect of heterospecific pollen (HP) on reproduction success is variable and depends on the identity… read more here.

DOI: 10.1007/s00442-019-04379-z
Abstract: Evaluation of pollen transfer in wild plant communities revealing heterospecific pollen receipt is common, yet experimental hand pollinations have revealed high among-species variation in the magnitude of its effect on recipient fitness. The causes of… read more here.

DOI: 10.1111/1365-2745.13520
Abstract: The ecological dynamics of co‐flowering communities are largely mediated by pollinators. However, current understanding of pollinator‐mediated interactions primarily relies on how co‐flowering plants influence attraction of shared pollinators, and much less is known about plant–plant… read more here.
