“…Spatial variability within habitats has also been studied as part of ecological risk assessment [22][23][24]. These few studies argue against a general rule that species and food chains in one habitat are more vulnerable than in another.…”

Nature development in The Netherlands is often planned on contaminated soils or sediments. This contamination may present a risk for wildlife species desired at those nature development sites and must be assessed by specific risk assessment methods. In a previous study, we developed a method to predict ecological vulnerability in wildlife species by using autecological data and expert judgment; in the current study, this method is further extended to assess ecological vulnerability of food chains and terrestrial and aquatic habitats typical for The Netherlands. The method is applied to six chemicals: Cd, Cu, Zn, dichlorodiphenyltrichloroethane, chlorpyrifos, and ivermectin. The results indicate that species in different food chains differ in vulnerability, with earthworm-based food chains the most vulnerable. Within and between food chains, vulnerability varied with habitat, particularly at low trophic levels. The concept of habitat vulnerability was applied to a case study of four different habitat types in floodplains contaminated with cadmium and zinc along the river Dommel, The Netherlands. The alder floodplain forest habitat contained the most vulnerable species. The differences among habitats were significant for Cd. We further conclude that the method has good potential for application in mapping of habitat vulnerability.

a b s t r a c tThe biogeomorphological functioning of lowland floodplains will be altered strongly due to future landscaping measures that are necessitated by climate change. For many industrialized and urbanized river basins, the layout of the fluvial area depends on the human choices for landscaping measures, which reflect the dominant value system of the actors. We aimed at (1) designing scenarios for the future layout of the floodplains of the River Waal in the Netherlands for 2050 using a new value-based methodology, and (2) assessing the floodplain biogeomorphology under these scenarios and climate change. The scenarios are driven by transitions in human value systems and they are color-coded: green (personalistic-consensual), orange (scientific-rational), and yellow (integrated-systemic). Per scenario, the landscaping measures were translated into a future topography and ecotope distribution. Using various spatially explicit simulation models, we evaluated the scenarios regarding the biogeomorphology in 2050: (1) flood peak reduction (green 0.11, orange 0.65, and yellow 0.37 m), (2) year-average floodplain suspended sediment deposition (+114, +148, +143%), (3) food web exposure to heavy metals (4-5 out of 10 species for all scenarios) and (4) biodiversity value (+23, −4, +39%). We conclude that (1) analysis of value systems provides a broad interpretive framework for scenario development, which guides the choices for transitions and (2) the biogeomorphology is affected by climate change (+58% deposition), but the effects of the local landscaping measures are even stronger. None of the scenarios shows the ideal combination of high flood peak reduction, low sedimentation, and high biodiversity. Ecotoxicological risks seem less discriminative.

“…Indeed, studies pertaining to sites that are distinctly different with respect to for example land use or the degree of human disturbance showed that relatively coarse taxonomic arthropod data were sufficient to discriminate between the sites, despite a relatively large degree of taxonomic bifurcation (Biaggini et al 2007;Nakamura et al 2007). The lowland floodplains along the Rhine river in The Netherlands are characterized by considerable environmental heterogeneity, due to both natural processes and human influences (Schipper et al 2008a). On a small spatial scale, relatively large differences can be found with respect to e.g., elevation, flooding, soil characteristics, and vegetation types.…”

Four arthropod datasets of different taxonomic detail were compared on their discriminatory power for various environmental characteristics in a lowland floodplain area along the river Rhine. The arthropod datasets comprised ground-dwelling arthropods at class-order level (n = 10), beetle families (n = 32), ground beetle genera (n = 30) and ground beetle species (n = 68). Environmental characteristics included vegetation characteristics, hydro-topographic setting, physical-chemical soil properties and soil contamination levels. Relations between arthropod assemblages and environmental factors were assessed with variance partitioning: a multivariate statistical approach that attributes variation in community composition to specific explaining variables. The variance partitioning showed comparable results for the four datasets. A substantial part of the variation (31-38%) could be ascribed to vegetation characteristics. Variance could further be attributed to physical-chemical soil properties (7-10%), hydro-topographic setting (3-7%) and soil metal contamination (2-4%). Thus, in strongly heterogeneous landscapes like lowland river floodplains, relatively coarse taxonomic data can already provide a valuable indication of the relative importance of different environmental factors for structuring arthropod communities. However, the ground beetles showed a higher specificity for different vegetation types and a more distinct relation to soil contamination levels than the other arthropod datasets. Hence, a higher degree of taxonomic detail will be beneficial for investigating the consequences of for example environmental pollution or vegetation characteristics in terms of taxonomic diversity or community composition.
