Differentiating diploids from triploids at the earliest life stage possible allows for a more efficient use of resources including production time and rearing space. Thus, a reliable flow cytometric (FCM) method has been developed to discriminate triploids from diploids at the larval stage. In order to help simplify the process of differentiating triploids from diploids, we propose a simple...

Dozens of species of non-native fishes are present in the freshwaters of Florida, and new species are discovered each year. Maintaining current information on the geographic ranges of all non-native fishes is a daunting task, as many jurisdictions are involved at the state, federal, and municipal levels. There is a need to coordinate sampling, research and management across jurisdictional...

Disentangling the mechanisms regulating coastal wetland sustainability in the face of rising sea levels
Date Published: March 14, 2017

USGS scientists have been involved for a number of years in the development and use of Structural Equation Modeling (SEM). This methodology represents an approach to statistical modeling that focuses on the study of complex cause-effect hypotheses about the mechanisms operating in systems. SEM is increasingly used in ecological and environmental studies and this site seeks to provide...
