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

Intraspecific Variation In The Recruitment Dynamics Of A Transgressing Avicennia Germinans Population, Shannon Victoria Grogan
Intraspecific Variation In The Recruitment Dynamics Of A Transgressing Avicennia Germinans Population, Shannon Victoria Grogan

Survival and establishment of mangrove propagules at higher tidal elevations beyond the landward margin of their distribution is a requirement for the continued existence of mangrove populations in response to rising sea-level. Despite the growing body of literature that discusses mangrove recruitment patterns, few studies have empirically examined establishment and post-establishment growth success of propagules at the higher intertidal positions into witch mangrove populations are migrating. Using an experimental field approach, this study compares establishment and post-establishment growth success of propagules at three positions across a tidal elevation gradient within a landward-transgressing mangrove population of SW Florida (USA). I observed …
Ecological Interactions Influencing Avicennia Germinans Propagule Dispersal And Seedling Establishment At Mangrove-Saltmarsh Boundaries, Jennifer Mcclain Peterson
Ecological Interactions Influencing Avicennia Germinans Propagule Dispersal And Seedling Establishment At Mangrove-Saltmarsh Boundaries, Jennifer Mcclain Peterson

Mangroves and saltmarshes are ecologically important coastal ecosystems; unfortunately, these low-lying coastal ecosystems are vulnerable to global climate change. As sea-levels rise, mangroves are expected to shift their distribution landward towards higher elevation sites that are occupied by other plants, including saltmarsh taxa. Therefore, mangrove recruits at the leading edge of expansion may interact with diverse assemblages of saltmarsh plants, and these interactions could influence the success of mangrove encroachment into higher tidal-elevation areas. The purpose of the research presented here was to investigate empirically the ecological interactions that may influence the recruitment of the black mangrove, Avicennia germinans, …
