Dynamics of baseline stable isotopes within a temperate coastal ecosystem: Relationships and projections using physical and biogeochemical factors
… energy flow and trophic positions in aquatic foodwebs; comparing food webs; and aiding in the tracking of wide-ranging consumers. However, each of these applications requires accurate measurements of isotopic signatures in organisms at or near the base of the food web (e.g. autotrophs and …

The effect of recreational fishing on targeted fishes and trophic structure, in a coral reef marine park
Recreational line fishing is highly targeted at predatory fishes, making them vulnerable to overfishing. These same fishes play a role in trophic structure by regulating prey species. Despite increasing numbers of fishers, few studies have investigated the potential effects of recreational fishing …

Predation Vulnerability and Trophic Interactions of Pallid Sturgeon Scaphirhynchus albus
Recruitment of the federally endangered pallid sturgeon Scaphirhynchus albus in the Missouri River has been absent or at levels too low to sustain the population. Mortality of juvenile fishes is often greatest during their first year of life, and may have large implications for recruitment dynamics …
