The intermittent upwelling hypothesis (IUH) predicts that the strength of
ecological subsidies, organismal growth responses, and species interactions will vary
unimodally along a gradient of upwelling from persistent downwelling to persistent upwelling,
with maximal levels at an intermediate or ‘‘intermittent’’ state of upwelling. To test this model,
we employed the...
The proliferation of efficient fishing practices has promoted the depletion of
commercial stocks around the world and caused significant collateral damage to marine
habitats. Recent empirical studies have shown that marine reserves can play an important role
in reversing these effects. Equilibrium metapopulation models predict that networks of marine
reserves...
The impact of herbivores on primary producers in differing oceanographic
regimes is a matter of intense ecological interest due to ongoing changes in their abundance,
that of their predators, and anthropomorphic alteration of nutrient cycles and climatic
patterns. Interactions between productivity and herbivory in marine habitats have been
studied on...

Galápagos intertidal meta-ecosystem

Ecosystems are shaped by processes occurring and interacting over multiple
temporal and spatial scales. Theory suggests such complexity can be simplified by focusing on
processes sharing the same scale as the pattern of interest. This scale-dependent approach to
studying communities has been challenged by multiscale meta-ecosystem theory, which
recognizes that...
