Winter post-droughts amplify extreme nitrate concentrations in German rivers
Hydrological extremes can affect nutrient export from catchments to streams, posing a threat to aquatic ecosystems. In this study, we investigated the effects of hydrological drought on nitrate concentrations in the streamflow of 182 German catchments from ...
Bristol2024Calibration of ground surface albedo models
Christophe Ballif, Pierre-Jean Alet, Arttu Matias Tuomiranta
The emergence of bifacial photovoltaics as a serious option for large-scale power generation makes the accuracy of the in-situ estimation of ground surface albedo increasingly critical. Recent studies have evaluated the performance of different models but ...
PERGAMON-ELSEVIER SCIENCE LTD2022The effects of previous summer drought and fertilization on winter non-structural carbon reserves and spring leaf development of downy oak saplings
Xiaoyu Wang, Yue Yang, Peng He
It is still unknown whether the previous summer season drought and fertilization will affect the winter non-structural carbohydrate (NSC) reserves, spring leaf development, and mortality of trees in the next year. We, therefore, conducted an experiment wit ...
FRONTIERS MEDIA SA2022Photosynthetic acclimation and sensitivity to short- and long-term environmental changes in a drought-prone forest
Future climate will be characterized by an increase in frequency and duration of drought and warming that exacerbates atmospheric evaporative demand. How trees acclimate to long-term soil moisture changes and whether these long-term changes alter trees' se ...
OXFORD UNIV PRESS2022Towards understanding the characteristics of new particle formation in the Eastern Mediterranean
To quantify the contribution of new particle formation (NPF) to ultrafine particle number and cloud condensation nuclei (CCN) budgets, one has to understand the mechanisms that govern NPF in different environments and its temporal extent. Here, we study NP ...
2021Root carbon and nutrient homeostasis determines downy oak sapling survival and recovery from drought
The role of carbon (C) and nutrient uptake, allocation, storage and especially their interactions in survival and recovery of trees under increased frequencies and intensities of drought events is not well understood. A full factorial experiment with four ...
2021Exploring the relationship between urban form and land surface temperature (LST) in a semi-arid region Case study of Ben Guerir city - Morocco
Surface temperature is one of the critical factors used to study microclimate conditions through Land surface Temperature (LST), a widely used data source. This paper tests a classification approach using moderate spatial satellite resolution images to ext ...
2021Genetically Different Isolates of the Arbuscular Mycorrhizal Fungus Rhizophagus irregularis Induce Differential Responses to Stress in Cassava
Water scarcity negatively impacts global crop yields and climate change is expected to greatly increase the severity of future droughts. The use of arbuscular mycorrhizal fungi (AMF) can potentially mitigate the effects of water stress in plants. Cassava i ...
FRONTIERS MEDIA SA2020Soil nutrient availability alters tree carbon allocation dynamics during drought
Drought alters allocation patterns of carbon (C) and nutrients in trees and eventually impairs tree functioning. Elevated soil nutrient availability might alter the response of trees to drought. We hypothesize that increased soil nutrient availability stim ...
2020Drought alters the biogeochemistry of boreal stream networks
Drought is a global phenomenon, with widespread implications for freshwater ecosystems. While droughts receive much attention at lower latitudes, their effects on northern river networks remain unstudied. We combine a reach-scale manipulation experiment, o ...
