Marisa T Martinez, PhD

Marisa is a Biologist at the USGS Wetland and Aquatic Research Center interested in using ecological models to understand species-habitat associations and predict how species will respond to environmental change.

Marisa's primary research interests include avian species and their habitats. Before joining USGS, Marisa's research focused on modeling spatiotemporal availability of foraging habitat for wading birds in coastal south Florida, occupancy modeling of saltmarsh sparrows in coastal Maine and Massachusetts, and post-fledging habitat use patterns of black-capped vireos in central Texas.

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 field researc

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 hydrologi

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 resolution or hig
