| مستخلص: | Exponential population growth and the increased demand of land for food production present the challenge to secure enough food for everyone whilst preserving natural landscapes and biodiversity. The targets of biodiversity conservation and food production have been historically perceived as conflicting, yet the productivity of many crops is maximised by pollinator abundance and diversity. The Ecosystem Service approach addressed this dichotomy by putting emphasis on the benefits that humans obtain from conserving biodiversity. An example is ensuring a diverse food supply by maintaining diverse pollinator communities. Pollinators are intimately connected to our welfare, securing a variety of food and maintaining ecosystem function and health. Consequently, the ongoing global decline of wild pollinators prompted a growing body of research on the extent to which reproductive success of plants is enhanced by flower-visiting animals and how land-use change affects wild pollinators. The overarching aim of this thesis is to understand how losing pollination services can affect human well-being. The objectives of my research are: (1) to elucidate pollinator contribution to wild and crop plants; (2) to develop practical methods for pollination services site-scale assessment; and (3) to pilot the novel tools developed in this thesis in a nature reserve within an agricultural matrix. Little is known about the potential consequences of losing vertebrate pollinators on plants. I used a systematic review protocol to give an overview of the importance of vertebrate pollinators for the reproductive success of the plants they pollinate. Based on a meta-analysis of 126 experiments on animal-pollinated plants, I found that an exclusion of vertebrates from plants visited by both insects and vertebrate pollinators may reduce fruit and seed production by 63%. Model selection based on Akaike’s Information Criterion (AIC) further revealed that tropical plants are more reliant on |
