Rapid heating events, such as heatwaves, are becoming more frequent and intense as a result of climate change. Importantly, such extreme weather events can be more important drivers of extirpation and selection than changes in annual or seasonal averages and they pose a particularly large threat to poikilothermic organisms. In this study, we evaluate the thermal stress response of a...
DeepFaune New England DeepFaune New England
This repository contains code for training and running the DeepFaune New England (DFNE) model for species classification in trail camera imagery. This model is a re-trained version of the DeepFaune model for classifying European species in trial cameras, fine-tuned to classify taxa from northeastern North America. The DFNE model takes as input cropped images of each animal, which can be...
Pysochron Pysochron
Pysochron is a Python-based tool designed to calculate isochron burial ages from in-situ cosmogenic 26Al and 10Be data. It uses orthogonal distance regressions to fit isochron lines to 1000 Monte Carlo simulations of nuclide concentration measurements to account for uncertainty, and allows the user to modify various aspects of the fitting process, including constants relating to the...
Code to Estimate Walrus Herd Density at Multiple Terrestrial Haulouts Code to Estimate Walrus Herd Density at Multiple Terrestrial Haulouts
This is nimble model code for a hierarchical Bayesian analysis to estimate walrus herd density at multiple sites, where some surveys entailed counting walruses in a sample of grid cells overlain on the surveyed herd on shore; whereas, other surveys were censuses (complete counts.) The model code also predicts herd densities for new surveys taken at existing sites and a new site.
