Author(s): Obedzinski, Mariska; Nossaman Pierce, Sarah; Horton, Gregg E; Deitch, Mathew J | Abstract: While many studies have established the importance of streamflow as a driver of fish population dynamics, few have examined relationships between su

Many coastal estuaries in Mediterranean climates are susceptible to inlet closures resulting from barrier beach formation. These closures are ecologically important because they eliminate tidal exchange and connectivity of nekton movement to the coas

Robust estimates of survival and movement are important for informing the recovery of fish populations as well as for the study of life history, behavior, and population ecology. We present a multistate capture–recapture model that allows separate

Scale and ontogeny are important in understanding how various ecological processes structure populations. This is expected to be the case for density-dependent effects (DDE), which influence the population dynamics of many organisms. Our goal was to

Portable passive integrated transponder (PIT) tag antenna systems can be valuable in providing reliable estimates of the abundance of tagged Atlantic salmon Salmo salar in small streams under a wide range of conditions. We developed and employed PIT

We estimated the magnitude and shape of size-dependent survival (SDS) across multiple sampling intervals for two cohorts of stream-dwelling Atlantic salmon ( Salmo salar ) juveniles using multistate capture–mark–recapture (CMR) models. Simulation

The inability to account for the availability of individuals in the study area during capture-mark-recapture (CMR) studies and the resultant confounding of parameter estimates can make correct interpretation of CMR model parameter estimates difficult

Our goal was to understand movement and its interaction with survival for populations of stream salmonids at long-term study sites in the northeastern United States by employing passive integrated transponder (PIT) tags and associated technology. Alt

Accurate assessments of fish populations are often limited by re-observation or recapture events. Since the early 1990s, passive integrated transponders (PIT tags) have been used to understand the biology of many fish species. Until recently, PIT app

Electroshocking and tagging of fish with passive integrated transponder (PIT) tags are two commonly used methods for conducting mark–recapture studies in freshwater environments and are frequently used in combination. We conducted an experiment to
