Stephanie Romañach, Ph.D.
Stephanie uses a combination of field observations and predictive ecological models to explore the impacts of climate change and ecosystem restoration on wildlife.
Stephanie leads Joint Ecosystem Modeling (JEM), focused on developing predictive ecological models and decision support tools that help decision makers explore potential ecological impacts from ecosystem restoration and climate change. In addition to her work on Everglades restoration and conservation planning in Florida, she also works on natural resources conservation in Africa and Asia.

Climate downscaling effects on predictive ecological models: a case study for threatened and endangered vertebrates in the southeastern United States Climate downscaling effects on predictive ecological models: a case study for threatened and endangered vertebrates in the southeastern United States
High-resolution (downscaled) projections of future climate conditions are critical inputs to a wide variety of ecological and socioeconomic models and are created using numerous different approaches. Here, we conduct a sensitivity analysis of spatial predictions from climate envelope models for threatened and endangered vertebrates in the southeastern United States to determine whether...

Use and interpretation of climate envelope models: a practical guide Use and interpretation of climate envelope models: a practical guide
This guidebook is intended to provide a practical overview of climate envelope modeling for conservation professionals and natural resource managers. The material is intended for people with little background or experience in climate envelope modeling who want to better understand and interpret models developed by others and the results generated by such models, or want to do some...

Do bioclimate variables improve performance of climate envelope models? Do bioclimate variables improve performance of climate envelope models?
Climate envelope models are widely used to forecast potential effects of climate change on species distributions. A key issue in climate envelope modeling is the selection of predictor variables that most directly influence species. To determine whether model performance and spatial predictions were related to the selection of predictor variables, we compared models using bioclimate...

The American crocodile in Biscayne Bay, Florida The American crocodile in Biscayne Bay, Florida
Intensive crocodile monitoring programs conducted during the late 1970s and early 1980s in southern Florida resulted in an optimistic outlook for recovery of the protected species population. However, some areas with suitable crocodile habitat were not investigated, such as Biscayne Bay and the mainland shorelines of Barnes and Card Sounds. The objective of our study was to determine...

Ecological conditions in the Greater Everglades have changed due to human activities, including the construction of canals to divert water away from the core of the landscape. Current and planned restoration projects are designed to produce a natural sheetflow of water across the landscape. This restoration of water flow should provide an increase in freshwater needed to restore natural...

Joint Ecosystem Modeling (JEM) ecological model documentation volume 1: Estuarine prey fish biomass availability v1.0.0 Joint Ecosystem Modeling (JEM) ecological model documentation volume 1: Estuarine prey fish biomass availability v1.0.0
Estuarine fish serve as an important prey base in the Greater Everglades ecosystem for key fauna such as wading birds, crocodiles, alligators, and piscivorous fishes. Human-made changes to freshwater flow across the Greater Everglades have resulted in less freshwater flow into the fringing estuaries and coasts. These changes in freshwater input have altered salinity patterns and...
