“…These results differ markedly from other sediment organic enrichment studies in vegetated subtidal environments and suggest that mechanisms unique to both the intertidal environment and seagrass removal will influence the relative importance of sediment organic content on seagrass recolonization following small-scale disturbances. While our data did not show any effects of SOC on seagrass recovery, several studies have demonstrated that additional sediment factors such as composition and texture (Kenworthy and Fonseca 1977, Balestri et al 1998, Park and Lee 2007 and nutrient content (Kenworthy and Fonseca 1977, Peralta et al 2003, Cambridge and Kendrick 2009 can play an important role in both natural recovery and artificial restoration processes. With seagrass decline on the rise, and with interest in seagrass restoration practices as a means to mediate global and local seagrass decline, more information on sediment processes following disturbance is required to predict and delineate optimal seagrass recovery conditions.…”

Disturbance and Recovery of Intertidal Mixed Seagrass Communities

Disturbances are a key driver in determining the structure and function of the ecological landscape by altering resource availability, community composition and species interactions. For seagrass habitats, most research has focused on subtidal temperate or subtropical systems. Because tropical systems tend to have higher species diversity and are exposed to more types of disturbances, we have a weak understanding of how species-rich intertidal seagrasses recover from different types of disturbances or how these disturbances influence habitat heterogeneity within the landscape.This dissertation investigated the responses, including recovery, of mixed-species intertidal seagrass communities to disturbances at the population, community and landscape level. Key findings include: (1) both macro-scale (tidal gradient) and microscale (disturbance) factors influence seagrass zonation and species diversity patterns across the intertidal landscape in the species-rich Indo-Pacific region; (2) seagrass recolonization in mixed species intertidal meadows is complex, suggesting that recovery prediction using two dimensional seagrass succession models is limited and should incorporate a third dimension -elevation changes produced by specific disturbance types and placement along a tidal gradient; (3) infauna abundance and diversity does not return to original levels even when seagrass biomass returns to pre-disturbance levels, suggesting that the return of ecosystem functions such as habitat utilization may lag behind plant recovery and that monitoring of above-ground plant components is not an accurate indication of full community recovery; (4) changes in sediment organic content iii following seagrass removal in intertidal meadows is not an important factor in smallscale recovery, which differs from experimental studies in subtidal seagrass habitats that found negative affects on seagrass growth; (5) intertidal seagrass meadows are highly dynamic, and the creation of bare gaps within vegetated areas by disturbances can influence habitat heterogeneity at local and landscape scales; and (6) small-size gaps created by disturbances can persist for years and in some cases even expand, and therefore should be included in studies of spatial patterns and landscape dynamics. These findings build upon our general understanding of disturbance ecology in seagrass ecosystems, underline differences between subtidal and intertidal systems, and have applications to prediction efforts and restoration activities in seagrass ecosystems throughout the world. Plant Dynamics: Disturbance and seagrass recovery Disturbances in seagrass habitatsDisturbance in the context of this dissertation is defined as any relatively discrete event in time that disrupts ecosystem, community, or population structure and that results in Seagrass community succession following a disturbanceThere is a rich and diverse body of literature that addresses disturbance recovery from both theoretical and applied perspectives (see Picket and White, 1985 for rev...
