The menace of momentum: dynamic forces on flexible organisms

Article Abstract:

Flexible organisms in wave-swept environments are subject to inertial forces that can be large enough to offset gains accrued from moving with the flow. The model of a spring-mass system with hydrodynamic forcing and the model of a mass on a discontinuous spring approximate the forces acting on wave-swept organisms. The jerk number, a dimensionless index, is suggested as an indicator of the importance of inertial forces. The model is applied to kelps and mussels as real-world examples.

Species diversity, species extinction, and ecosystem function

Article Abstract:

The contributions of resource use complementarity and species dominance are examined for their impact on both species diversity and extinction. Ecosystem function variability with species diversity is influenced by the level of resource use overlap between the species, but extinction variation patterns are dependent solely on preextinction species diversity, rather than resource use complementarity or dominance.

Temperature or transport? Range limits in marine species mediated solely by flow

Article Abstract:

Research suggests that marine fauna are successfully restricted to a specific geographic range by common flow fields in ocean currents. Boundary leakiness, or a species' willingness to leave its geographic range, depends on temporal variability levels of the nearshore flow and species life-history characteristics.
