A comprehensive multi-state conditional occupancy model for evaluating interactions of non-native and native species
Patti J. Wohner, Paul D. Scheerer, Michael H. Meeuwig, James T. Peterson
2023, Frontiers in Ecology and Evolution (10)
A major challenge in ecology is disentangling interactions of non-native, potentially invasive species on native species. Conditional two-species occupancy models examine the effects of dominant species (e.g., non-native) on subordinate species (e.g., native) while considering the possibility that occupancy of one species may affect occupancy and/ or detection of...
Long-term, high-resolution permafrost monitoring reveals coupled energy balance and hydrogeologic controls on talik dynamics near Umiujaq (Nunavik, Québec, Canada)
Philippe Fortier, Jean-Michel Lemieux, Nathan L Young, Michelle A. Walvoord, Richard Fortier
2023, Water Resources Research (59)
Rising temperatures in the Arctic and subarctic are driving the rapid thaw of permafrost by reducing permafrost cooling, increasing active layer thickness, and promoting talik formation. In this study, the cyrohydrogeology of a permafrost mound located within the discontinuous permafrost zone near Umiujaq (Nunavik, Québec, Canada) is...

Modeling coho salmon (Oncorhynchus kisutch) population response to streamflow and water temperature extremes
J. Ryan Bellmore, Christopher J. Sergeant, Rebecca A. Bellmore, Jeffrey A. Falke, Jason B. Fellman
2023, Article
Models that assess the vulnerability of freshwater species to shifting environmental conditions do not always account for short-duration extremes, which are increasingly common. Life cycle models for Pacific salmon (Oncorhynchus spp.) generally focus on average conditions that fish experience during each life stage, yet many floods, low flows, and elevated water...

Inferring geologic structure from gravity anomalies: Proceed with caution
Geoffrey Phelps
2023, Conference Paper, Geologic mapping forum 22/23 abstracts
Characterization of key geologic structures within a study region, such as basin depths, fault offsets, and fault dip, are often derived from gravity data. Gravity modeling of such subsurface geologic structure generally assumes either homogeneous or spatially uncorrelated densities within modeled rock bodies and overlying sediments. This assumption allows modeling...
