Projected sea-level rise and high tide flooding at San Juan National Historic Site, Puerto Rico
IntroductionNational parks and preserves in the South Atlantic-Gulf Region contain valuable coastal habitats such as tidal wetlands and mangrove forests, as well as irreplaceable historic buildings and archeological sites located in low-lying areas. These natural and cultural resources are vulnerable to accelerated sea-level rise and escalating high tide flooding events. Through a Natural Resource
Modeling the effects of temperature and limiting nutrients on the competition of an invasive floating plant, Pontederia crassipes, with submersed vegetation in a shallow lake
The potential for a non-native plant species to invade a new habitat depends on broadscale factors such as climate, local factors such as nutrient availability, and the biotic community of the habitat into which the plant species is introduced. We developed a spatially explicit model to assess the risk of expansion of a floating invasive aquatic plant species (FAV), the water hyacinth (Pontederia
An integrative paradigm for building causal knowledge
A core aspiration of the ecological sciences is to determine how systems work, which implies the challenge of developing a causal understanding. Causal inference has long been approached from a statistical perspective, which can be limited and restrictive for a variety of reasons. Ecologists and other natural scientists have historically pursued mechanistic knowledge as an alternative approach to

Invasive Burmese Pythons in Southern Florida
Invasive species represent a significant threat to global biodiversity and a substantial economic burden to surrounding communities. In the last 40 years, the Burmese python ( Python bivittatus ) has invaded southern Florida, including Everglades National Park, Big Cypress National Preserve, and other protected lands.
Decision Support for Managers Restoring Texas Coastal Marshes with Beneficial Use of Dredged Material
USGS researchers will define the range of elevation targets supporting optimal plant performance and oil strength by identifying the lower and upper thresholds of marsh conversion, and characterize ecosystem development of restored marshes over time to identify the lifetime and sustainability of restored marsh during sea-level rise. This work addresses priority science needs to improve restoration...
A Case Study Assessing the Cumulative Effects of Deepwater Horizon Restoration Projects on Barrier Island/Barrier Shoreline Ecosystem Resilience in the North-central Gulf of Mexico
USGS and partners will assess the potential cumulative effects of restoration projects on the resiliency of barrier islands and barrier shorelines in the north-central Gulf of Mexico.
