Climate change, landscape homogenization, and the decline of beneficial insectsthreaten pollination services to wild plants and crops. Understanding how pollinationpotential (i.e. the capacity of ecosystems to support pollination of plants) is affectedby climate change and landscape homogenization is fundamental for our ability topredict how such anthropogenic stressors affect plant biodiversity. Models of pollina-tor potential are improved when based on pairwise plant–pollinator interactions andpollinator’s plant preferences. However, whether the sum of predicted pairwise interac-tions with a plant within a habitat (a proxy for pollination potential) relates to pollendeposition on flowering plants has not yet been investigated. We sampled plant–beeinteractions in 68 Scandinavian plant communities in landscapes of varying land-coverheterogeneity along a latitudinal temperature gradient of 4–8°C, and estimated pollendeposition as the number of pollen grains on flowers of the bee-pollinated plants Lotuscorniculatus and Vicia cracca. We show that plant–bee interactions, and the pollinationpotential for these bee-pollinated plants increase with landscape diversity, annual meantemperature, and plant abundance, and decrease with distances to sand-dominatedsoils. Furthermore, the pollen deposition in flowers increased with the predicted pol-lination potential, which was driven by landscape diversity and plant abundance. Ourstudy illustrates that the pollination potential, and thus pollen deposition, for wildplants can be mapped based on spatial models of plant–bee interactions that incorpo-rate pollinator-specific plant preferences. Maps of pollination potential can be used toguide conservation and restoration planning. ecological networks, ecosystem service mapping, landscape diversity, plant–pollinator interactions, pollination
Abstract
This report describes some of the most unique and characteristic natural features and interdependencies between species and nature types at the Vega world heritage site, and how these habitats are intertwined with the continuity of human intervention. Foreseeable threats and change scenarios are then presented and discussed for the key natural features in Vega.
