Significance Forests are experiencing growing risks of drought-induced mortality in a warming world. Yet, ecosystem dynamics following drought remain unknown, representing major limitation to our understanding the ecological consequences climate change. We provide an emerging picture postdrought trajectories based on field indicators forest dynamics. Replacement patterns indicate limited short-term persistence predrought dominant tree species, highlighting potential for reorganization coming...
Uncertainties surrounding tree carbon allocation to growth are a major limitation projections of forest sequestration and response climate change. The prevalence extent which assimilation (source) or cambial activity (sink) mediate wood production fundamentally important remain elusive. We quantified source-sink relations across biomes by combining eddy-covariance gross primary with extensive on-site regional ring observations. found widespread temporal decoupling between growth, underpinned...
Reviews of the current statuses forests and impacts climate change on exist at (sub)continental scale, but rarely country regional levels, meaning that information causal factors, their impacts, specific properties is often inconsistent lacking in depth. Here, we present status forest production biogeochemistry expected them for Belgium. This work represents a case study temperate oceanic zone, most important bioclimatic zone northwestern Europe. Results show Belgian are mainly young, very...
The primary role of land surface models embedded in climate is to partition available energy into upwards, radiative, sensible and latent heat fluxes. Partitioning evapotranspiration, ET, fundamental importance: as a major component the total flux, ET affects simulated water balance, related consequently feedbacks with atmosphere. In this context it also crucial credibly represent CO2 exchange between ecosystems their environment. study, JULES, model used UK weather models, has been...
Forested catchments are generally assumed to provide higher quality water. However, this hypothesis must be validated in various contexts as interactions between multiple land use and cover (LULC) types, ecological variables water render relationship highly complex. This paper applies a straightforward multivariate approach on typical large monitoring dataset of managed densely populated area (Wallonia, Belgium; 10-year dataset), quantifying forest effects nine physico-chemical variables....
Abstract. Given the multiple abiotic and biotic stressors resulting from global changes, management systems practices must be adapted in order to maintain reinforce resilience of forests. Among others, transformation monocultures into uneven-aged mixed stands is an avenue improve forest resilience. To explore response these new silvicultural under a changing environment, one needs models combining process-based approach with detailed spatial representation, which quite rare. We therefore...
The persistence of the woody vegetation Sahelian savannas, and their supported ecosystem functions, have been questioned since great drought 1970s–1980s. To assess resilience this to grazing, we undertook a trait-based approach using field inventory, historical survey databases, traits data literature. Using hierarchical clustering approach, gathered species present from 1970 2015 into functional groups according effect related primary productivity biogeochemical cycles. First, studied...
Since 2013, pedunculate oak (Quercus robur L.) mortality has been observed in the Ardennes region of Belgium. We aimed to understand current decline by retrospectively (1945–2015) studying radial growth patterns trees classified three health statuses (reference, declining, and dying) linking them abiotic biotic hazard history, which we recorded quantified. Our results show that is a long-term process, with 1987 as tipping point for trajectories declining dying trees. That year was preceded...
Abstract. Climate change affects forest growth in numerous and sometimes opposite ways, the resulting trend is often difficult to predict for a given site. Integrating structuring knowledge gained from monitoring experimental studies into process-based models an interesting approach response of ecosystems climate change. While first generation operates at stand level, one now needs spatially explicit individual-based approaches order account individual variability, local environment...
