Polar Region Ecosystems
Polar ecosystems are dominated by ice both on land and at sea. The terrestrial component of these ecosystems varies between the poles with regard to biodiversity and the importance of modern and historic glaciations. Polar ecosystems have been affected by human activities ranging from oil exploration to harvesting of marine mammals. The polar region ecosystems form integrated systems in which plants and animals are linked together and are tightly…
Scale-Dependent Correspondence of Floristic and Edaphic Gradients across Salt Marsh Creeks
Biogeographers emphasize the presence of scale-dependence in vegetation–environment relationships. This research addresses the issue of scale-dependence, focusing on spatial correspondence of floristic and edaphic gradients across salt marsh creeks at Skallingen, Denmark. We employed a hierarchical approach, which compared vegetation and soil gradients at both fine and coarse scales. At the fine scale, we used ordination techniques to identify th…
Relationships between Arctic shrub dynamics and topographically derived hydrologic characteristics
Shrub expansion is a global phenomenon that is gaining increased attention in the Arctic. Recent work employing the use of oblique aerial photographs suggested a consistent pattern of positive change in shrub cover across the North Slope of Alaska. The greatest amounts of change occurred in valley slopes and floodplains. We studied the association between shrub cover change and topographically derived hydrologic characteristics in five areas in n…
Wind-Driven Sea-Level Variation Influences Dynamics of Salt Marsh Vegetation
Long-term variation of mean sea level has been considered the primary exogenous factor of vegetation dynamics in salt marshes. In this study, we address the importance of short-term, wind-induced rise of the sea surface in such biogeographic changes. There was an unusual opportunity for examining field data on plant species frequency, sea-level variation, and sedimentation acquired from the Skallingen salt marsh in Denmark since the 1930s. The en…
Salt Marshes as Potential Indicators of Global Climate Change
Coastal scientists postulate that salt marshes are significantly affected by dynamics of global climate. However, few studies have explicitly proposed a perspective that regards salt marshes as potential indicators of climate change. This review article evaluates the possibility of salt marshes as indicators of global climate change, focusing upon three major aspects: sedimentary, vegetation, and biogeochemical dynamics. The previous literature c…
Spatial heterogeneity and domain of scale on the Skallingen salt marsh, Denmark
Geografisk Tidsskrift—Danish Journal of Geography 109(1):95–104, 2009 Spatial heterogeneity and the domain of scale over which such heterogeneity is observed are fundamental topics in biogeography. Focusing upon two facets of heterogeneity, or spatial point pattern and spatial texture (i.e. arrangement of patches and gaps), this study quantified how these facets vary across scales on the Skallingen salt marsh, Denmark. We established a 10 m x 10 …
