1 The effects of tree diversity on herbivore–enemy interactions have received relatively little attention and even fewer studies have compared the relative influence of tree intra- versus interspecific diversity on such dynamics. 2 We evaluated the effects of mahogany (Swietenia macrophylla) genotypic diversity and tree species diversity on parasitoid attack and species richness associa…
Multiple factors determine plant reproductive success and their influence may vary spatially. This study addresses several factors influencing female reproductive success in three populations of Ruellia nudiflora, specifically we: (i) determine if fruit set is pollenlimited and if pollinator visitation rates are related to this condition; (ii) estimate fruit set via autonomous self-pollination …
