Evolution in Helianthemum oelandicum (Cistaceae) – evidence of Holocene differentiation in morphology on the Baltic island of Öland, south-eastern Sweden

Autor: Björn Widén, Eman Soubani, Mikael Hedrén, Oskar Löfgren, Marie Widén

Publikováno v: Botanical Journal of the Linnean Society. 202:270-293

We use Helianthemum oelandicum subsp. oelandicum as a model for studies of mechanisms shaping the diversity in a rapidly radiating lineage of the H. oelandicum aggregate. Locally, correlations between drainage conditions (using GIS to measure variati

Grasslands ancient and modern: Soil nutrients, habitat age and their relation to Ellenberg N

Autor: Karin Hall, Barbara Christine Schmid, Honor C. Prentice, Oskar Löfgren

Publikováno v: Journal of Vegetation Science. 31:367-379

Questions: To what extent does the long-term process of grassland succession reflect changes in nutrient availability or other effects of grassland history? Plant communities in ancient, semi-natural pastures include many species associated with nutr

Landscape history confounds the ability of the NDVI to detect fine‐scale variation in grassland communities

Autor: Thomas Moeckel, Karin Hall, Barbara Christine Schmid, Honor C. Prentice, Oskar Löfgren

Publikováno v: Methods in Ecology and Evolution. 9:2009-2018

The NDVI is a remotely sensed vegetation index that is frequently used in ecological studies. There is, however, a lack of studies that evaluate the ability of the NDVI to detect fine-scale variation in grassland plant community composition and speci

Airborne hyperspectral data predict Ellenberg indicator values for nutrient and moisture availability in dry grazed grasslands within a local agricultural landscape

Autor: Oskar Löfgren, Honor C. Prentice, Lars Eklundh, Thomas Möckel, Karin Hall

Publikováno v: Ecological Indicators. 66:503-516

Species-based ecological indices, such as Ellenberg indicators, reflect plant habitat preferences and can be used to describe local environment conditions. One disadvantage of using vegetation data as a substitute for environmental data is the fact t
