TL;DR: It is shown that populations of shelf-dwelling sharks derive a substantial proportion of their carbon from regional pelagic sources, but contain individuals that forage within additional isotopically diverse local food webs, such as those supported by terrestrial plant sources, benthic production and macrophytes.

TL;DR: It is suggested that either grazing is a factor in shaping the seasonal bloom or bloom shape determines whether a habitat is conducive to diapause, while recognizing that both factors can re-enforce each other.

TL;DR: In this paper, the authors analyzed remotely-sensed ocean color data at two spatial scales, one based on ecologically defined sub-units of the ecosystem and the other on a regular grid (0.5°).
Elasticity Analyses Of Size-Based Red And White Abalone Matrix Models: Management And Conservation
TL;DR: This work is an example of how prospective elasticity analyses of size-structured matrix models can be used to quantitatively evaluate research priorities, fishery management strategies, and conservation options.

TL;DR: In this article, the authors developed a trophic network model with 41 functional groups using ECOPATH re-expressed in a donor-driven, end-to-end format to directly evaluate the efficiency of large jellyfish and forage fish at transferring energy to higher trophoric levels, as well as the ecosystemwide effects of varying jellyfish consumption rates and fishing rates, in the Northern Humboldt Current system (NHCS) off of Peru.
