Abstract
Cephalopods, especially squids, are
believed to have a structuring role in marine ecosystems
as a link between different trophic levels,
primarily due to their voracious prey consumption
and high production rate. Cephalopod ecology, however,
is still poorly understood as observational studies
often give highly uncertain and variable results due to
the peculiarities of cephalopod behaviour and biology,
and their responsiveness to external drivers. This
review evaluates our representation of cephalopods in
ecosystem models and the insights given by these
models on the role of cephalopods in our oceans. We
examined ecosystem models from 13 regions to
analyse the representation of cephalopods and compared
their results to local trophic studies. Our analysis
indicated that most ecosystem models inadequately
include cephalopods in terms of model structure and
parametrization; although some models still have the capacity to draw valuable conclusions regarding the
impact and role of cephalopods within the system.
Oceanic squid species have a major role linking
trophic levels and food webs from different habitats.
The importance of neritic species varies locally, but
generally cephalopods have a substantial impact via
their consumer role. To better understand the ecological
role of cephalopods, improved representation of
these species in ecosystem models is a critical
requirement and could be achieved relatively easily
to more accurately articulate the mechanisms regulating
the ecological role of cephalopods.
