An attempt is made to rank 41 steady-state models of aquatic ecosystems on the basis of
their maturity. Maturity is quantified using several of Odum's attributes of ecosystem maturity …

Keystones are defined as relatively low biomass species with a structuring role in their food
webs. Thus, identifying keystone species in a given ecosystem may be formulated as:(1) …

We performed a global assessment of how fish biomass has changed over the last 100 yr,
applying a previously developed methodology using ecological modeling. Our assessment …

Dynamic simulations of 18 ecopath mass-balance marine trophic models are used to
explore the stability of systems when briefly impacted by a fishery on the keywasp …

Exploited ecosystems are characterised by exports of secondary production from each
fished trophic level that reduce the energy available for upper levels at the ecosystem scale …

We built a trophic network based on a matrix of interspecific trophic relationships to assess
the role of elasmobranch fishes in sha** community structure of the Gulf of Tortugas in the …

Ecosystem-focused models have, for the first time, become available for the combined
demersal and pelagic components of a large tropical lake ecosystem, Lake Malawi. These …

Abstract The Gulf of Mexico (GoM) is a valuable ecosystem both socially and economically,
and fisheries contribute substantially to this value. Gulf menhaden, Brevoortia patronus …

Small-scale fisheries in Mexico account for about 97% of the marine fleet. These fisheries
cover about 70% of the continental shelf, which accounts for 10% of the exclusive economic …

We constructed a mass-balanced model of a benthic ecosystem exploited by shrimp trawlers
in the Gulf of California, Mexico. The model is based on the software ecopath with ecosim …
