De ontwikkeling van een streefbeeld voor het Schelde estuarium op basis van de ecosysteemfuncties, benaderd vanuit de functie natuurlijkheid Instituut voor Natuur- en Bosonderzoek
Dit rapport is een aanzet om te komen tot een zo objectief mogelijke ontwikkeling van een streefbeeld voor het Schelde estuarium in 2030 vanuit het oogpunt “natuurlijkheid”. Hierbij is gebruik gemaakt van de “goods & services” van een ecosysteem. Dit principe is bekend geraakt door een publicatie in Nature (Costanza et al, 1997), waarbij deze “goods & services” op een globale schaal werden gekoppeld aan economische waarden. Bij deze ...
Predicting the responses of European grassland communities to climate and land cover change. KU Leuven
European grasslands are among the most species-rich ecosystems on small spatial scales. However, human-induced activities like land use and climate change pose significant threats to this diversity. To explore how climate and land cover change will affect biodiversity and community composition in grassland ecosystems, we conducted joint species distribution models (SDMs) on the extensive vegetation-plot database sPlotOpen to project ...
Explore Before You Restore: Incorporating Complex Systems thinking in Ecosystem Restoration KU Leuven
Wetness severity increases abrupt shifts in ecosystem functioning in arid savannas KU Leuven
The accelerating pace of climate change has led to unprecedented shifts in surface temperature and precipitation patterns worldwide, with African savannas being among the most vulnerable regions. Understanding the impacts of these extreme changes on ecosystem health, functioning and stability is crucial. This paper focuses on the detection of breakpoints, indicative of shifts in ecosystem functioning, while also determining relevant ecosystem ...
Estimating vegetation water content from Sentinel-1 C-band SAR data over savanna and grassland ecosystems KU Leuven
Studying vegetation water content (VWC) dynamics is essential for understanding plant growth, water and carbon cycles, and ecosystem stability. However, acquiring field-based VWC estimates, consistently through space and time, is challenging due to time and resource constraints. This study investigates the potential of Sentinel-1 C-band Synthetic Aperture Radar (SAR) data for estimating VWC in natural ecosystems in central Brazil. We assessed ...
Using airborne LiDAR to map forest microclimate temperature buffering or amplification KU Leuven
Mapping the microclimate effect of forest canopies on understory temperature requires spatially explicit predictors at very fine spatial resolutions. Light Detection And Ranging (LiDAR) offers promising prospects in that regard, as it allows capturing the vertical dimension of vegetation structure at a very high resolution over large areas. To explore the potential of airborne LiDAR-derived metrics to predict understory temperature, we focused ...
