Аннотация: Biodiversity loss impairs ecosystem functioning and, hence, nature's contributions to people (well established) (3.2.1, 3.2.2, 3.2.3). Sustainable delivery of these contributions requires the maintenance of genetic diversity, species diversity, and the diversity of ecosystems and land- and seascapes (well established) (3.2.4). The Показать полностьюdelivery of individual functions over time and at different places, and the delivery of multiple contributions, requires higher biodiversity than provisioning single services at one place and time alone (well established) (3.2.5). Higher biodiversity increases the capacity of terrestrial, freshwater or marine systems to capture resources, produce biomass, decompose and recycle nutrients, and to provide pollination (well established) (3.2.1, 3.2.2). Higher biodiversity facilitates stable ecosystem functioning and improved capacity for evolutionary adaptation (well established) (3.2.3, 3.2.4). Higher biodiversity also increases ecosystem resilience and biological control of pathogens and invasive alien species (established but incomplete) (3.2.1, 3.2.3). To support ecosystem functioning, ecosystem stability over time, and adaptation to future environmental changes, biodiversity is required at different levels, from genetic and phenotypic diversity within populations, to diversity among populations and ecological or morphological types within species, species diversity and phylogenetic and functional diversity within communities, and diversity of communities, ecosystems and land and seascapes (well established) (3.2.3). The higher the number of nature's contributions to people, the longer the time span, and the larger the area, the more biodiversity is required for their delivery (well established) (3.2.5). At the land and seascape and larger spatial scales, biotic homogenization, i.e. increasing similarity of the sets of organisms found at different places, reduces nature's overall contributions to people (established but incomplete), because of trade-offs between different facets of biodiversity and different contributions of nature to people (well established) (3.2.5). Thus, at the landscape and larger spatial scale the supply of multiple contributions of nature to people requires the maintenance and promotion of high biodiversity (established but incomplete). This implies high synergy at the land and seascape level between maintaining and promoting biodiversity and maintaining and promoting multiple contributions of nature to people (3.2.5).
