Results of this study show the utility of using delta 15N to characterize trophic level andtrophic transfer of POPs but highlight the effects of species and chemical differences on trophIC transfer of Pops that can be overlooked when a single magnification factor is applied to an entire food web.
delta15N and delta13C diet-tissue discrimination factors for large sharks under semi-controlled conditions.
Aquatic animal telemetry: A panoramic window into the underwater world
A brave new world with a wider view Researchers have long attempted to follow animals as they move through their environment, but such efforts were limited to short distances and times in species large enough to carry large batteries and transmitters, while new technologies have opened up new frontiers in animal tracking remote data collection.
Rescaling the trophic structure of marine food webs
The resulting scaled Δ15N framework estimated reliable TPs of zooplanktivores to tertiary piscivores congruent with known feeding relationships that radically alters the conventional structure of marine food webs.

The present paper summarizes the recent literature with an emphasis on identifying important ecological factors for explaining variability of OC concentrations among organisms and introduces simplification into models developed to assess OC dynamics in aquatic food webs.
Dietary accumulation and depuration of hydrophobic organochlorines: Bioaccumulation parameters and their relationship with the octanol/water partition coefficient
Dietary accumulation of 23 hydrophobic organochlorines (OCs) by juvenile rainbow trout (Oncorhynchus mykiss) was studied with the objective of obtaining relationships between bioaccumulation…
A review of detection range testing in aquatic passive acoustic telemetry studies
This study presents a comprehensive review of how acoustic detection range has been considered and assessed to date, summarizes important variables to monitor when determining the detection range of a receiver array, and provides recommendations to account for detection range during experimental design, analysis and data interpretation.
