Watershed-wide land-cover proportions can be used to predict the in-stream non鈥損oint source pollutant loadings through regression modeling. However, the model performance can vary greatly across different study sites and among various watersheds. Existing literature has shown that this type of ...
EC flux tower observations, but the ensemble of Trendy models overestimated both Reco and NEE in the U.S. Midwest compared with flux tower observations (Fig.4e, f). In addition, the estimated distributions of GPP, Reco, and NEE vary widely among individual Trendy models, which may arise ...
Water scarcity contributes to the poverty of around one-third of the world’s people. Despite many benefits, tree planting in dry regions is often discouraged by concerns that trees reduce water availability. Yet relevant studies from the tropics are scarce and the impacts of intermediate tree cov...

The maximum rates of groundwater depth fluctuations are observed in places with low groundwater table, coarse-grained formations, and high groundwater withdrawal. Moreover, in the coasts located at the outlet of watersheds, the accumulation of surface water in those places and higher ...
Full size image Depending on whether the highest or lowest yielding soil type is selected in each grid cell, estimated climate change impacts expressed relatively to the yield obtained under present climatic conditions can vary widely within a certain FPU. In 75% of the major FPUs, relative medi...
Habitat threats and introduced species vary along a headwater to downstream continuum in prairie streams. Small headwaters are vulnerable to extreme temperature and oxygen stress as intermittency increases due to groundwater withdrawal and climate change. Mid-sized streams are altered by dewatering from ...
Full size image Versatile peroxidase Similar to previous peroxidases, versatile peroxidase (VP) also presents a glycoprotein structure with a molecular weight varying between 38 and 45 kDa, with heme in the central region, functioning as an enzyme cofactor. VP has been originally reported in thePleu...
In light of the established role of filter-feeding invertebrates in reducing suspended bacterial concentrations [7], it is possible that filter-feeding ammocoetes may contribute to ecosystem health by reducing concentrations of bacteria in watersheds. However, the effects of ammocoetes on pathogenic ...
