Climate change versus land-use change : what affects the ecosystem services more in the forest-steppe ecotone? Universiteit Gent
Validation of the sigmoid wave curve fitting algorithm on a forest-tundra ecotone in the Northwest Territories, Canada Universiteit Antwerpen
Ecotones are gradual transitions between two adjacent ecological systems. Ecotones are characterized by their spatial properties which are reflected in an ecotone width and location and the temporal variation across time during succession or environmental change on both a local and a global scale. If only one main environmental factor drives this gradual change the shape of the ecotone is evident as a sigmoid wave. In this paper we explore a ...
A resource-based conservation approach for an endangered ecotone species Instituut voor Natuur- en Bosonderzoek
Ecotones (i.e., transition zones between two or more communities of considerable length that are narrower than the adjoining community areas themselves) are often species-rich and harbour specific resources and environmental conditions for invertebrates. Despite their functional significance for conservation, they are often not explicitly included in biotope typologies relevant to conservation policy and management (e.g., the European Habitats ...
Changes in soil labile and recalcitrant carbon pools after land-use change in a semi-arid agro-pastoral ecotone in Central Asia Universiteit Gent
Soil organic matter is a heterogeneous and complex entity that consists of a diverse range of compounds. However, the responses of soil organic carbon (SOC) fractions with different biochemical stabilities to land-use change are inadequately addressed. In this study, soil samples (0-60 cm) were collected with a 10 cm interval from grassland (GS), cropland (CS), woodland (WS), and orchard (OS) using paired-site approach in a typical semi-arid ...
Redéfinir l’écotopie : utopie et écotone urbain en Afrique subsaharienne à partir de Rouge impératrice de Léonora Miano Universiteit Gent
Disentangling the role of forest structure and functional traits in the thermal balance of the Mediterranean-temperate ecotone Universiteit Gent
The thermal balance of forests is the result of complex land-atmosphere interactions. Different climate regimes and plant functional types can have contrasting energy budgets, but little is known about the influence of forest structure and functional traits. Here, we combined spaceborne measurements of surface temperature from ECOSTRESS with ground-based meteorological data to estimate the thermal balance at the surface ( ?Tcan-air) during four ...
Land use influences arbuscular mycorrhizal fungal communities in the farmingpastoral ecotone of northern China Universiteit Antwerpen
We performed a landscape-scale investigation to compare the arbuscular mycorrhizal fungal (AMF) communities between grasslands and farmlands in the farmingpastoral ecotone of northern China. AMF richness and community composition were examined with 454 pyrosequencing. Structural equation modelling (SEM) and multivariate analyses were applied to disentangle the direct and indirect effects (mediated by multiple environmental factors) of land use ...
Sensitivity of the grassland-forest ecotone in East African open woodland savannah to historical rainfall variation Universiteit Gent
Evaluation of Random Forest and Adaboost tree-based ensemble classification and spectral band selection for ecotope mapping using airborne hyperspectral imagery Vrije Universiteit Brussel
Detailed land use/land cover classification at ecotope level is important for environmental evaluation. In this study, we investigate the possibility of using airborne hyperspectral imagery for the classification of ecotopes. In particular, we assess two tree-based ensemble classification algorithms: Adaboost and Random Forest, based on standard classification accuracy, training time and classification stability. Our results show that Adaboost ...
