Cadiz Bay is a shallow mesotidal lagoon with extensive populations of the seagrass Cymodocea nodosa at intertidal and shallow subtidal elevations. This work aims to understand the mechanisms behind the resilience of this species to gradual sea level rise by studying its acclimation capacity to depth along the shallow littoral, and therefore, to gradual variations in the light environment. To address this objective, these populations have been monitored seasonally over a 10 year period, representing the longest seasonal database available in the literature for this species.

- Seagrass interacts with water currents, affecting the survival of species that feed on particles, like filter feeders.
- An experiment revealed that the density and arrangement of seagrass impacts the amount of edible particles available, influenced by the presence of filter-feeding organisms like cockles.
- The study suggests that areas with low seagrass density offer better protection and more resources for filter feeders, while dense patches concentrate resources within, impacting feeding efficiency.
An in-depth knowledge of solutes advection and turbulent diffusion is crucial to estimate dispersion area and retention time (t(R)) of pollutants within seagrass habitats. However, there is little knowledge on the influence of seagrass habitat fragmentation on such mechanisms. A set of dye tracer experiments and acoustic Doppler velocimeter measurements (ADV) were conducted.
