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.

Defining conservation targets on a landscape-scale Defining conservation targets on a landscape-scale
Conservation planning, the process of deciding how to protect, conserve, enhance and(or) minimize loss of natural and cultural resources, is a fundamental process to achieve conservation success in a time of rapid environmental change. Conservation targets, the measurable expressions of desired resource conditions, are an important tool in biological planning to achieve effective...

Performance metrics and variance partitioning reveal sources of uncertainty in species distribution models Performance metrics and variance partitioning reveal sources of uncertainty in species distribution models
Species distribution models (SDMs) are widely used in basic and applied ecology, making it important to understand sources and magnitudes of uncertainty in SDM performance and predictions. We analyzed SDM performance and partitioned variance among prediction maps for 15 rare vertebrate species in the southeastern USA using all possible combinations of seven potential sources of...

Modeling apple snail population dynamics on the Everglades landscape Modeling apple snail population dynamics on the Everglades landscape
Context The Florida Everglades has diminished in size and its existing wetland hydrology has been altered. The endangered snail kite (Rostrhamus sociabilis) has nearly abandoned the Everglades, and its prey, the apple snail (Pomacea paludosa), has declined. Objective We developed a population model (EverSnail) to understand apple snail response to inter- and intra-annual fluctuations in...

EverVIEW: a visualization platform for hydrologic and Earth science gridded data EverVIEW: a visualization platform for hydrologic and Earth science gridded data
The EverVIEW Data Viewer is a cross-platform desktop application that combines and builds upon multiple open source libraries to help users to explore spatially-explicit gridded data stored in Network Common Data Form (NetCDF). Datasets are displayed across multiple side-by-side geographic or tabular displays, showing colorized overlays on an Earth globe or grid cell values, respectively...

Dynamic reserve design in the face of climate change and urbanization Dynamic reserve design in the face of climate change and urbanization
Reserve design is a process that must address many ecological, social, and political factors to successfully identify parcels of land in need of protection to sustain wildlife populations and other natural resources. Making land acquisition choices for a large, terrestrial protected area is difficult because it occurs over a long timeframe and may involve consideration future conditions...

Climate changes, shifting ranges Climate changes, shifting ranges
Even a fleeting mention of the Everglades conjures colorful images of alligators, panthers, flamingos, and manatees. Over the centuries, this familiar cast of characters has become synonymous with life in south Florida. But the workings of a changing climate have the potential to significantly alter the menagerie of animals that call this area home. Global projections suggest south...
