Saltmarshes Connectivity in Tropical Seascapes: An Ecohydrological Perspective (Old ID 27438)
Chief Investigator
Saltmarshes are among the most threatened coastal ecosystems on the planet. Yet, our understanding of their functionality and ecosystem value as productive coastal habitat is derived from only a small number of studies in temperate and subtropical zones, with almost nothing known about tropical saltmarshes. The proposed research aims to address this knowledge gap by providing insights into the importance of seascape connectivity and configuration on saltmarsh patches. The relationships between saltmarsh hydroperiod (frequency, duration and depth of saltmarsh flooding) and elevation on saltmarsh plants are first investigated. This information will then be used to examine the effects of hydroperiod and seascape configuration on the diets of saltmarsh crabs and their role as trophic subsidies supporting broader estuarine food webs. This study also attempts to investigate the vulnerability of saltmarshes to sea level rise and anthropogenic changes. Together, this research will quantitatively assess the importance and mechanisms of some of the drivers of saltmarsh connectivity in tropical seascapes, thus directly contributing to an ecologically meaningful understanding of these virtually unstudied, though under threat, ecosystems.
