Abstract Ecological Network Analysis (ENA) combines modeling and analysis used to
investigate the structure, function, and evolution of ecosystems and other complex systems …

In this paper, we review the state of the art and major challenges in current efforts to
incorporate biogeochemical functional groups into models that can be applied on basin …

Stable isotope mixing models are increasingly used to quantify consumer diets, but may be
misused and misinterpreted. We address major challenges to their effective application …

Stable isotopes are increasingly being used as tracers in environmental studies. One
application is to use isotopic ratios to quantitatively determine the proportional contribution …

The analysis of networks of ecological trophic transfers is a useful complement to simulation
modeling in the quest for understanding whole-ecosystem dynamics. Trophic networks can …

Ecological network analysis (ENA) is a systems-oriented methodology to analyze within
system interactions used to identify holistic properties that are otherwise not evident from the …

The continuing global decline of the health of the sea, and the increasing depletion of
marine resources and biodiversity, caused by human activity and climate change, have led …

More than a decade has passed since the realization that bacteria are quantitatively
important consumers of organic carbon in marine food webs. The basic information on the …

We present a quantitative food‐web analysis of the cold‐water coral community, ie, the
assembly of living corals, dead coral branches and sediment beneath, associated with the …

It is generally accepted that responsible stewardship of the ocean implies ecosystem-based
management. A requirement then arises for ecosystem indicators that can be applied in …
