Population Dynamics of Northern Pearl Dace Margariscus nachtriebi in Anthropogenically Altered Headwater Streams of the Nebraska Sandhills Ecoregion

River Research and Applications, EarlyView.
ABSTRACT Empirical evidence of population demographic responses to environmental perturbations is a major knowledge gap for aquatic vertebrate populations. Extensive habitat alteration including channelization of headwater streams influences the habitat template on which small‐bodied fish are dependent to carry out distinct life stages and maintain or ...

Assessing Spatial Riverbed Clogging and Its Dynamics at the Reach Scale: A Coupled Approach Combining Field Measurements and 1D Hydro‐Sedimentary Numerical Modeling

River Research and Applications, EarlyView.
ABSTRACT Assessing spatial and temporal variability of clogging in gravel‐bed rivers is challenging because field methods typically rely on labor‐intensive measurements of fine‐sediment content, porosity, or hydraulic conductivity. Clogging is also highly dynamic, driven by hydro‐sedimentary conditions; yet few studies have examined it at large scales ...

Semi‐automated seal detection on the Western Antarctic Peninsula: an unsupervised machine learning approach for detecting ice seals in aerial survey data

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a semi‐automated, rule‐based image analysis pipeline to detect ice seals in aerial surveys of the Western Antarctic Peninsula during an unusually low sea ice year. By using simple hierarchical clustering instead of deep learning, the method substantially reduced human annotation effort while achieving 82% recall, identifying 758 ...
