Evaluating Population Viability and Habitat Suitability for the Cape Sable Seaside Sparrow Under Future Climate and Management Conditions
WARC will assess Cape Sable seaside sparrow population response and viability under different management and habitat change scenarios. The USGS EverSparrow model will be run on future scenarios, and differences in the predicted probability of presence and the efficacy of varying conservation strategies will be evaluated.
Demographic Analysis of the Endangered Cape Sable Seaside Sparrow
USGS researchers will examine how hydrology and landscape vegetation changes impact Cape Sable Seaside Sparrow survival and population growth.

Ecological models facilitate evaluation of alternative approaches to restore the Greater Everglades ecosystem. However, the provision of useful and accessible models is a challenge because there is often a disconnect between model output and its use by decision makers. Joint Ecosystem Modeling (JEM) meets this challenge by providing ecological model output tailored to management...
Integrated Population Model & Population Viability Analysis of the Cape Sable Seaside Sparrow (CSSS, Ammospiza maritima mirabilis) Integrated Population Model & Population Viability Analysis of the Cape Sable Seaside Sparrow (CSSS, Ammospiza maritima mirabilis)
This software release contains the R code to jointly run an integrated population model (IPM) and Bayesian population viability analysis (BPVA) for the Cape Sable Seaside Sparrow (CSSS; Ammospiza maritima mirabilis). The CSSS is a federally endangered bird endemic to a small part of the Everglades in southern Florida, USA. The IPM-BPVA synthesizes thirty years (1992-2021) of range-wide...

This data release contains the R code to run an integrated population model (IPM) for the Cape Sable Seaside Sparrow (CSSS; Ammospiza maritima mirabilis), a federally endangered bird endemic to a small part of the Everglades in southern Florida, USA, and provides the parameter estimates from the model. The IPM synthesizes thirty years (1992-2021) of range-wide surveys, mark-resight, and...
Model code to build and run an integrated population model for the endangered Cape Sable Seaside Sparrow Model code to build and run an integrated population model for the endangered Cape Sable Seaside Sparrow
The Cape Sable Seaside Sparrow (CSSS; Ammospiza maritima mirabilis) is an endangered species that has experienced population declines of more than 60% since the 1990s. The CSSS is restricted in geographic extent to a relatively small area of remaining marl prairie in the southern Florida Everglades and remains in six subpopulation areas (named A-F). There has been over two decades of...
Linking environmental variability to long-term demographic change of an endangered species using integrated population models Linking environmental variability to long-term demographic change of an endangered species using integrated population models
Understanding how species populations change with environmental conditions is important for implementing effective habitat management and conservation strategies. Challenges to evaluating population-level responses to environmental conditions arise when data are sparse or not spatiotemporally aligned, especially for at-risk species with small, declining numbers.We synthesized 30 years...

Long-term demographic analysis of the Cape Sable seaside sparrow (1992–2021) Long-term demographic analysis of the Cape Sable seaside sparrow (1992–2021)
The Cape Sable seaside sparrow (Ammospiza maritima mirabilis) is an endangered species that has experienced a population decline of more than 60% since 1981. Despite its critical population status, a statistically robust analysis of the species’ demographic rates utilizing all data has yet to be completed (Benscoter et al. 2021). Furthermore, long-term population processes in response to

Evaluating temporal and spatial transferability of a tidal inundation model for foraging waterbirds Evaluating temporal and spatial transferability of a tidal inundation model for foraging waterbirds
For ecosystem models to be applicable outside their context of development, temporal and spatial transferability must be demonstrated. This presents a challenge for modeling intertidal ecosystems where spatiotemporal variation arises at multiple scales. Models specializing in tidal dynamics are generally inhibited from having wider ecological applications by coarse spatiotemporal...

Everglades Vulnerability Analysis Model (EVA) Everglades Vulnerability Analysis Model (EVA)
The Everglades Vulnerability Analysis (EVA) is a series of connected Bayesian networks that model the landscape-scale response of indicators of Everglades ecosystem health to changes in hydrology, salinity, and temperature on the landscape. The modeling framework currently predicts the probability of vegetation types, wading bird regional nest abundance, freshwater prey fish biomass...

This repository provides a workflow to run the Joint Ecosystem Modeling (JEM) tool EverWaders. The repository takes the published model (D'Acunto et al. 2021) and allows a user to generate hydrometrics and model predictions from daily water depth data derived from the Everglades Depth Estimation Network (EDEN) or the Regional Simulation Model (RSM).
