Software & Shiny Apps

Software

bayesmove

An R package for inferring latent behavioral states from animal movement data (telemetry and/or biologging) using non-parametric Bayesian methods. This includes features for pre-processing and analysis of data, as well as the visualization of model results. This framework does not rely on standard parametric probability density functions, which provides flexibility during model fitting. Further details regarding part of this framework can be found in Cullen et al. (2022) and Valle et al. (2022).

Shiny Applications

Green turtle occurrences compared to environmental layers

This app provides an interactive map for exploring green turtle (Chelonia mydas) tracks in the Gulf of Mexico, as well as along the coasts of Brazil and Qatar. Additionally, environmental layers (depth, net primary productivity, sea surface temperature) can be explored compared to turtle locations at each region on a monthly basis. These data are part of a study developing a transferable species distribution modeling approach.

Exploration of animal movement data

This app provides an interactive and dynamic platform for users to upload and visually explore their animal telemetry dataset. Options are provided to filter by each column of the uploaded data, as well as to interactively subset the individuals and time period that is being mapped. An interactive time series plot is linked to a Leaflet map for exploring particular patterns of interest within the data.

Invasive species expert elicitation

This app was created to assist with data collection for an expert elicitation workshop on current distributions of invasive species in the southeast US. Users are first asked to define habitat suitability for a number of classes from the National Land Cover Database per species. Next, users are asked to define the intensity of species occurrence throughout the region on a raster map. I developed this novel interactive tool to be used as a layer of a Leaflet map. Additional info about the workshop can be found here.

Walks with Turbo

A fun app for me to explore and visualize walks with my dog Turbo. This app emphasizes style customization with CSS and simple layouts using {bslib}. Photos from each walk also emphasize Turbo’s style and quirkiness. The dashboard includes a summary table of the distance, duration, and elevation gain of each walk, whereas an additional plot provides an elevation profile of the selected walk show on the interactive map. A popover map at the top of the sidebar enables visualization of all recorded walks.
