  abstract = {{H}abitat fragmentation generates a loss of functional connectivity detrimental to the persistence of biodiversity. {T}he {F}rench agricultural intensification initiated in the 1950s has caused a decline in field margins. {A}s field margins may facilitate species dispersal while providing socio-economic benefits, it is of interest to assess their contribution to the functional connectivity of insect-pollinated plants in agro-ecosystems. {T}his will help develop appropriate management strategies mitigating fragmentation. {W}e addressed this issue by studying the links between landscape structure and the patterns of abundance and pollen dispersal (using fluorescent dye particles) for two contrasted insect-pollinated plants occurring in field margins ({C}repis sancta and {E}uphorbia serrata). {W}e investigated the influence of field margins quality and of the surrounding matrix on pollen dispersal and compared the relevance of the least-cost algorithm with a straight-line approach to depict pollinators' movements. {T}he influence of landscape structure on plant abundance is species and scale-specific. {P}ollen dispersal decreases with distance from the source. {F}or {E}. serrata, it was preferentially dispersed via field margins, confirming the relevance of the least-cost algorithm, while {C}. sancta dispersal followed a straight-line. {E}uphorbia serrata, which grows strictly on field margins with a greater dispersal ability and a more diversified pollinator guild than {C}. sancta, is less affected by land-use changes. {O}ur study demonstrates the contrasting contributions of field margins to pollen dispersal as they may act as functional corridors favouring pollinators' movement depending on the species of interest.},
