Aim Change in spring phenology is a sensitive indicator of ecosystem response to climate change, and exerts first-order control on the ecosystem carbon and hydrological cycles. The start of season (SOS) in spring can be estimated from satellite data using different spatiotemporal scales, data sets and algorithms. To address the impacts of these differences(More)
A time-series of MODIS Terra daily 500m resolution surface reflectance data is investigated to examine the effect of current land management activity taking place on an upland peat site in North Wales. A catchment-scale controlled experiment has been set up to monitor the effect blocking of the artificial drainage channels ('grips') has on the ecosystem(More)
Light and water use by vegetation at the ecosystem level, are key components for understanding the carbon and water cycles particularly in regions with high climate variability and dry climates such as Africa. The objective of this study is to examine recent trends over the last 30 years in Light Use Efficiency (LUE) and inherent Water Use 8924 Efficiency(More)
The maximum photosynthetic carboxylation rate (Vcmax ) is an influential plant trait that has multiple scaling hypotheses, which is a source of uncertainty in predictive understanding of global gross primary production (GPP). Four trait-scaling hypotheses (plant functional type, nutrient limitation, environmental filtering, and plant plasticity) with nine(More)
component of the cell walls of some bacteria (Fig. 1). In that situation, the succinate is generated from the amino acid glutamine and acts to stabilize the transcription factor HIF-1α, which in turn leads to an increase in activity of HIF-1α-dependent genes, one of which encodes the pro-inflammatory molecule IL-1β (ref. 2). Of direct relevance to the(More)
