Special Issue Information

Dear Colleagues,

Most flowering plants rely on animals for pollination. However, there is an ongoing concern that anthropogenic-induced global change threatens pollinators and alter species phenology and, thus, threatens the service animal pollinators provide to plants. Two of the most important factors of global change are land-use and climate change. This Special Issue aims at highlighting new research that contributes to the understanding of: i) how land-use and/or climate influence plant–pollinator interactions, ii) the economic consequences of land-use and/or climate impacts on plant–pollinator interactions, such as crop plants and their pollinators, and iii) conservation implications of land-use and/or climate impacts on plant–pollinator interactions, for instance between threatened plants and their pollinators. We welcome studies on both natural systems and human modified landscapes, such as agricultural systems. The spatial scale of the studies may range from detailed local studies to the global scale.

Most flowering plants rely on animals for pollination and most animal pollinators rely on flowering plants for food resources. However, there is an ongoing concern that anthropogenic-induced global change threatens the mutualistic association between plants and pollinators. Two of the most important factors of global change are land-use and climate change. Land-use and climate change may affect species distributions and species phenologies, leading to spatial and temporal mismatches between mutualistic partners. Land-use and climate change may also influence species abundances, nesting habitats, floral resources and the behaviors of pollinators. Thus, mutualistic plant–pollinator interactions should be more susceptible to global change than simple measures of biodiversity, such as species richness and species composition. The potential negative impacts of land-use and climate change on plant–pollinator interactions may have large consequences for the conservation of threatened plants and pollinators and economically by diminishing crop productivity. Here I highlight ‘fruitful avenues’ for research into better understanding the influence of land-use and climate change on plant–pollinator interactions. Full article

West African savannas are severely threatened with intensified land use and increasing degradation. Bees are important for terrestrial biodiversity as they provide native plant species with pollination services. However, little information is available regarding their mutualistic interactions with woody plant species. In the first network study from sub-Saharan West Africa, we investigated the effects of land-use intensity and climatic seasonality on plant–bee communities and their interaction networks. In total, we recorded 5686 interactions between 53 flowering woody plant species and 100 bee species. Bee-species richness and the number of interactions were higher in the low compared to medium and high land-use intensity sites. Bee- and plant-species richness and the number of interactions were higher in the dry compared to the rainy season. Plant–bee visitation networks were not strongly affected by land-use intensity; however, climatic seasonality had a strong effect on network architecture. Null-model corrected connectance and nestedness were higher in the dry compared to the rainy season. In addition, network specialization and null-model corrected modularity were lower in the dry compared to the rainy season. Our results suggest that in our study region, seasonal effects on mutualistic network architecture are more pronounced compared to land-use change effects. Nonetheless, the decrease in bee-species richness and the number of plant–bee interactions with an increase in land-use intensity highlights the importance of savanna conservation for maintaining bee diversity and the concomitant provision of ecosystem services.

Stingless bees are vital pollinators for both wild and crop plants, yet their communities have been affected and altered by anthropogenic land-use change. Additionally, few studies have directly addressed the consequences of land-use change for meliponines, and knowledge on how their communities change across gradients in surrounding landscape cover remains scarce. Here, we examine both how local and landscape-level compositions as well as forest proximity affect both meliponine species richness and abundance together with pollination networks across 30 mixed fruit orchards in Southern Thailand. The results reveal that most landscape-level factors significantly influenced both stingless bee richness and abundance. Surrounding forest cover has a strong positive direct effect on both factors, while agricultural and urbanized cover generally reduced both bee abundance and diversity. In the local habitat, there is a significant interaction between orchard size and floral richness with stingless bee richness. We also found that pollinator specialization in pollination networks decreased when the distance to the forest patch increased. Both local and landscape factors thus influenced meliponine assemblages, particularly the forest patches surrounding an orchard, which potentially act as a key reservoir for stingless bees and other pollinator taxa. Preservation of forest patches can protect the permanent nesting and foraging habitat of various pollinator taxa, resulting in high visitation for crop and wild plants. Full article

Pollination by wild pollinators is a key ecosystem service threatened by anthropogenic-induced land-use change. The proximity to natural habitat has previously been shown to positively affect pollinator communities and improve crop yield and quality but empirical evidence is limited from most parts of the World. Here, across six farms in Southern Thailand, we investigated the significance of landscape-level effects of natural habitat (proportion of and distance to evergreen forest) on both visitation rate and richness of pollinators as well as fruit set of guava (Psidium guajava L.), a local economically-important crop in the tropics. Overall, the most abundant pollinator was the Asian honey bee Apis cerana (39% of all visits) and different species of stingless bees (37%). We found that pollinator richness was unrelated to the proportion and distance to evergreen forest, however, the proportion of forest within a 1, 5 and 10 km radius had a significant positive impact on visitation rate of wild pollinators. Still, neither the various forest parameters nor pollinator visitation rate showed a significant impact on fruit set of guava, perhaps because guava self-pollinates. This illustrates that landscape-level degradation of natural habitat may negatively impact pollinator communities without diminishing the crop yield of the farmers. Full article
