Habitat Heterogeneity Concentrates Predators In The Seascape: Linking Intermediate-Scale Estuarine Habitat To Striped Bass Distribution, Cristina Kennedy
Habitat Heterogeneity Concentrates Predators In The Seascape: Linking Intermediate-Scale Estuarine Habitat To Striped Bass Distribution, Cristina Kennedy
Masters Theses 1911 - February 2014
Predators are key components of aquatic ecosystems and innovative approaches to understanding their spatial distribution are imperative for research, effective management, and conservation. Discontinuities, created by abrupt changes between two unlike entities, are irregularly-distributed, intermediate-scale features that can have a disproportionate effect on organismal distribution within the seascape. Here I use the discontinuity concept to relate the distribution of a predator, striped bass (Morone saxatilis), to physical features within Plum Island Estuary (PIE), MA. I mapped the distribution of 50 acoustically-tagged striped bass during four monthly surveys at 40 sites to evaluate if heterogeneity in physical features concentrated …
