Differential fractionation of δ13C and δ15N among fish tissues: implications for the study of trophic interactions
TL;DR: White muscle was found to be less variable in δ 13 C and δ 15 N than all other tissues, and is probably the best tissue for use in ecological work, and may constitute a source of significant error in source material identification and dietary overlap.
Journal ArticleDOI
Resolving the effect of climate change on fish populations
TL;DR: Available evidence suggests climate-related changes in recruitment success to be the key process, stemming from either higher production or survival in the pelagic egg or larval stage, or owing to changes in the quality/quantity of nursery habitats.

TL;DR: Using a unique global database on consumer and resource body sizes, it is shown that the mean body-size ratios of aquatic herbivorous and detritivorous consumers are several orders of magnitude larger than those of carnivorous predators.

TL;DR: In this paper, the authors review the available literature on one type of indirect interaction in benthic marine ecosystems, which involve three or more trophic levels connected by predation, and infer how likely they are to affect the properties of communities following the implementation of marine protected areas (MPAs) or intensive resource exploitation.
Journal ArticleDOI
Weak cross-species relationships between body size and trophic level belie powerful size-based trophic structuring in fish communities
TL;DR: It is suggested that body size does not provide a useful surrogate of trophic level for individual species, but thatBody size is an excellent predictor of troPHic level within the community, providing an empirical basis for integrating community analyses based on models of Trophic structure and body size distributions.
