Data

Approximate Dynamic Programming relies on forward simulation of the system, so two population projection models are used, one for crabs and one for red knots. The two models are linked: HSC abundance is a predictor variable in the REKN model. Other useful outputs are produced as well, such as predictions of future harvest.

This software involves R script to fit models of abundance of mosquito vectors (' Script_for_ECS22-0193_9_13_2215.R') to landscape and environmental covariates using INLA and SPDE. The dataset used for this analysis were originally provided by the Pennsylvania Department of Environmental Protection (DEP) with a confidentiality agreement. The majority of the data used in this study...

This software involves files to fit the physiologically-guided abundance (PGA) model ('fish_predictions_pga.R'), a naive model ('fish_predictions_naive.R'), and a PGA model using simulated data ('PGA_sim.R'). Each R file calls as associated .stan file that contains the model code that is executed by stan when running the R code ('fish_prediction.stan', 'fish_prediction_naive.stan', and...

AMMonitor is an open source R package dedicated to collecting, storing, and analyzing AMU information in a way that 1) is cost-effective, 2) can efficiently process and store information, and 3) can take advantage of the vast and growing community of R analytics.

Small, surface-release dams are ubiquitous across the U.S. and have the potential to alter stream flow, impede sediment and nutrient transport, and fragment biotic assemblages. To mitigate these and other ecological impacts and reduce public safety hazards, dam removal has become an increasingly prevalent method of stream restoration. However, few streams have been consistently monitored...

This dataset contains locations acquired from GPS-tagged Brown Pelicans in the South Atlantic Bight. Locations correspond to the movements of pelicans tracked during the autumn migratory period (post-breed to the following spring, with length of deployment varying individually) from 2017-2020. Additional metrics include intrinsic and extrinsic variables both measured and acquired which...

The American alligator (Alligator mississippiensis) is a species of ecological and economic importance in the southeastern United States. Within South Carolina, alligators are subject to private and public harvest programs, as well as nuisance removal. These management activities can have different impacts across alligator size classes that may not be apparent through widely-used...

Shinymgr is an R package that provides a unifying framework for managing and deploying Shiny applications that consist of modules. Developers use the shinymgr framework to write modules and seamlessly combine them into Shiny apps, and users of these apps can execute reproducible analyses that can be incorporated into reports for rapid dissemination. The package includes 11 instructional...

Line-transect distance sampling (LTDS) surveys are commonly used to estimate abundance of animals or objects. In terrestrial LTDS surveys of gopher tortoise (Gopherus polyphemus) burrows, the presence of ground-level vegetation significantly decreases detection of burrows of all sizes, but no field or analytical methods exist to control for spatially heterogeneous vegetation obstruction...

R code and .stan files for fitting physiologically guided abundance models for predicting climate change impacts on poikilotherms.

R-based script used to simulate patterns of co-occurrence among two hypothetical species under patterns of avoidance, aggregation, and independence when the closure assumption is met or not, analyze simulated patterns with two-species occupancy models, and summarize the results.

This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 2 (Kauffman et al. 2022) and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations. This data release provides the means for ungulate migrations to be mapped and...
