Pollinator dependence and pollination deficit in Hedera helix, and effects on frugivore feeding choices

open access: yesJournal of Pollination Ecology
English ivy (Hedera helix) is an important resource for wildlife in rural and urban ecosystems. It provides pollen and nectar for flower-visiting insects during autumn and fruits for frugivores during winter and spring.

The Strength and Drivers of Bird-Mediated Selection on Fruit Crop Size: A Meta-Analysis

open access: yesFrontiers in Ecology and Evolution, 2018
In seed-dispersal mutualisms, the number of fruit a plant displays is a key trait, as it acts as a signal for seed dispersers that entails fruit removal and exportation of reproductive units (fruit crop size hypothesis).
