Among-individual variation in pollen limitation and inbreeding depression in a mixed-mating shrub

Description: Background and Aims: Variation in inbreeding depression (δ) among individual plants is considered to play a central role in mating system evolution and population genetics. Moreover, such variation could be linked to individual susceptibility to pollen limitation (PL) because those individuals stron...

The Labile Limits of Forbidden Interactions

Description: Forbidden links are defined as pairwise interactions that are prevented by the biological traits of the species. We focus here on the neglected importance of intraspecific trait variation in the forbidden link concept. We show how intraspecific trait variability at different spatiotemporal scales, a...

Long-term demographic consequences of a seed dispersal disruption

Description: The loss or decline of vertebrate frugivores can limit the regeneration of plants that depend on them. However, empirical evidence is showing that this is still very scarce, as functionally equivalent species may contribute to maintain the mutualistic interaction. Here, we investigated the long-term...

Who dispersed the seeds? The use of DNA barcoding in frugivory and seed dispersal studies

Description: Assessing dispersal events in plants faces important challenges and limitations. A methodological issue that limits advances in our understanding of seed dissemination by frugivorous animals is identifying 'which species dispersed the seeds'. This is essential for assessing how multiple frugivore sp...

Total Bee Dependence on One Flower Species Despite Available Congeners of Similar Floral Shape

Description: Extreme specialization is a common phenomenon in antagonistic biotic interactions but it is quite rare in mutualistic ones. Indeed, bee specialization on a single flower species (monolecty) is a questioned fact. Here, we provide multiple lines of evidence on true monolecty in a solitary bee (Flavipa...

Mutualistic relationships under landscape change: Carnivorous mammals and plants after 30 years of land abandonment

Description: © 2014 Gesellschaft für Ökologie. Little is currently known about the dynamics of mutualistic interactions in relation to land abandonment. Using data from two studies on frugivory and seed dispersal by carnivorous mammals carried out at the same site, and spanning three decades, we show how plant-f...

Contrasting heterozygosity-fitness correlations between populations of a self-compatible shrub in a fragmented landscape

Description: The mechanisms underlying heterozygosity-fitness correlations (HFCs) are subject of intense debates, especially about how important population features such as size or degree of isolation influence HFCs. Here, we report variation in HFCs between Large and Small populations of a self-compatible shrub...
