2 days ago · Hydropower is a rapidly developing and globally important source of renewable electricity. Globally, over 60% of rivers longer than 500 km are already fragmented and thousands of dams are proposed ...
4 days ago · We analyzed fish and macroinvertebrate communities separately: these two assemblages are commonly studied in tandem to assess lotic ecosystem quality as the different groups of taxa vary in sensitivity and response magnitude, both spatially and temporally, to different environmental stimuli (Feio et al. Citation 2023).
1 day ago · Water column removal in streams is a nitrogen (N) cycling pathway that has been historically overlooked. Studies filling this knowledge gap have focused on the role of water column N removal in mid-to-large-order rivers with consistently high suspended sediment concentrations.
5 days ago · The OpenFOAM model is a tool to assess small local processes that exacerbate erosion in lotic systems. NBS simulation allows for an effective assessment of eroded bank restoration interventions. Abstract
2 days ago · Their dispersal mechanisms (e.g., drifting, aerial dispersal), particularly in lotic ecosystems, along with their sensitivity to environmental changes, make them ideal models for studying the mechanisms driving biodiversity [16,25]. In this study, we selected 41 sampling sites from mountain streams in northwestern Hubei Province to (1) elucidate the taxonomic, functional, and phylogenetic ...
2 days ago · Context The North American beaver (Castor canadensis) was extirpated from much of its range in the US in the 1800s due to fur trapping and change in land use. However, the species has recolonised much of its former range, including the US state of Ohio. Since 2013, the Ohio Division of Wildlife (ODOW) has monitored trends in beaver colony density via aerial surveys of 40km×40km plots ...
5 days ago · Accurate estimates of methylmercury (MeHg) exposure are valuable to actionably assess risk and protect wildlife and human health. MeHg trophic transfer is a critical driver of risk: MeHg is generally biomagnified by a factor of 8.3 ± 7.5 from one trophic level to the next, averaged across freshwater communities (mean ± standard deviation). This variability can produce disparate risks even ...
