Grasslands are recognized as biodiversity hotspots in Europe. However, protection and management of these habitats are currently constrained by a limited understanding of what determines local grassland plant diversity patterns. Here, we combined vegetation records (8,639 inventory plots) from 258 semi-natural grasslands with fine-resolution topographic(More)
Salt meadows are thought to be vulnerable to habitat loss under future sea-level rise (SLR) due to inundation and compression of coastal environments (coastal squeezing). The extent of this threat is poorly understood due to the lack of geographically comprehensive impact assessments. Here, we linked vegetation data for Danish salt meadows to novel very(More)
a r t i c l e i n f o Airborne Laser Scanning (ALS) data for generating Digital Terrain Models (DTM) at national level are often collected during leaf-off seasons. Leaf-off data are useful for classifying evergreen and deciduous trees since echoes at lower intensity are returned from deciduous trees when compared to evergreen trees. In addition to this, the(More)
The two North Atlantic eel species, the European and the American eel, represent an ideal system in which to study parallel selection patterns due to their sister species status and the presence of ongoing gene flow. A panel of 80 coding-gene SNPs previously analyzed in American eel was used to genotype European eel individuals (glass eels) from 8 sampling(More)
As pre-hibernating larvae of the marsh fritillary (Euphydryas aurinia) have limited mobility essential resources need to be available at a very local scale. We surveyed larval webs (2011–2013), the host plant devil’s bit scabious (Succisa pratensis) (2012), and derived variables from digital orthophotos and digital elevation models (Normalized Differenced(More)
Soil organic carbon (SOC) is one of the most important carbon stocks globally and has large potential to affect global climate. Distribution patterns of SOC in Denmark constitute a nation-wide baseline for studies on soil carbon changes (with respect to Kyoto protocol). This paper predicts and maps the geographic distribution of SOC across Denmark using(More)
a r t i c l e i n f o Keywords: Airborne LASER SCANNING LiDAR Vertical canopy cover Angular canopy closure Ellenberg indicator values for light Canopy cover and canopy closure are two closely related measures of vegetation structure. They are used for estimating understory light conditions and their influence on a broad range of biological components in(More)
After centuries of range contraction, many megafauna species are recolonizing parts of Europe. One example is the red deer (Cervus elaphus), which was able to expand its range and is now found in half the areas it inhabited in the beginning of the 19th century. Herbivores are important ecosystem engineers, influencing e.g. vegetation. Knowledge on their(More)
With land privatization and fencing of thousands of hectares of communal grazing areas, East Africa is struggling with one of the most radical cultural and environmental changes in its history. The 668,500-hectare Greater Mara is of crucial importance for the great migrations of large mammals and for Maasai pastoralist culture. However, the magnitude and(More)
