Red Mangrove (Rhizophora Mangle) Recruitment And Retention Dynamics On Eastern Oyster (Crassostrea Virginica) Reefs In A Subtropical Estuary, Noreen Selma Mathews Oct 2023

Red Mangrove (Rhizophora Mangle) Recruitment And Retention Dynamics On Eastern Oyster (Crassostrea Virginica) Reefs In A Subtropical Estuary, Noreen Selma Mathews

USF Tampa Graduate Theses and Dissertations

Mangroves are invading oyster reefs in areas no longer impacted by winter freezes and completely transforming them into mangrove islands. The mechanisms influencing the transition between these two habitat states remain unclear. Here, I test experimentally whether oyster reef (Crassostrea virginica) structure directly facilitates red mangrove (Rhizophora mangle) propagule capture via differences in propagule retention and successful mangrove establishment. In addition to oyster reef structure, I compared physical reef features of size, elevation, and wind-wave exposure to uncover whether these traits influenced mangrove retention. Recently- abscised red mangrove propagules were inserted onto 21 oyster reefs across 5 sites in Tampa …
