| Zusammenfassung |
| We investigated how interactions between hydrography, topography and species
ecology influence the assembly of species and functional traits across
multiple spatial scales of a cold-water coral reef seascape. In a novel
approach for these ecosystems, we used a spatially resolved complex
three-dimensional flow model of hydrography to help explain assembly
patterns. Forward-selection of distance-based Moran's eigenvector mapping
(dbMEM) variables identified two submodels of spatial scales at which
communities change: broad-scale (across reef) and fine-scale (within reef).
Variance partitioning identified bathymetric and hydrographic gradients
important in creating broad-scale assembly of species and traits. In
contrast, fine-scale assembly was related more to processes that created
spatially autocorrelated patches of fauna, such as philopatric recruitment in
sessile fauna, and social interactions and food supply in scavenging
detritivores and mobile predators. Our study shows how habitat modification
of reef connectivity and hydrography by bottom fishing and renewable energy
installations could alter the structure and function of an entire cold-water
coral reef seascape. |
