چکیده
The QFASA model uses several sources of data, each of which requires careful consideration by the researcher (Iverson et al. 2004). We evaluated the sensitivity of QFASA diet estimates to the following model inputs: prey species included (prey library), fatty acid (FA) subsets, and calibration coefficients (CC). We did this by repeatedly estimating diets for all seals (harp seals Pagophilus groenlandicus n = 526; hooded seals Cystophora cristata n = 153) with different combinations of these inputs and evaluating differences among these combinations.

Extensive geographic and ontogenetic variation characterizes the trophic ecology of a temperate reef fish on southern California (USA) rocky reefs.
Interactions between predator and prey act to shape the structure of ecological communities, and these interactions can differ across space. California sheephead Semicossyphus pulcher are common predators of benthic invertebrates in kelp beds and rocky reefs in southern California, USA. Through gut content and stable isotope (δ13C and †15N) analyses, we investigated geographic and ontogenetic v...

متن کاملPopulation characteristics of a recovering US Virgin Islands red hind spawning aggregation following protection.
Many species of groupers form spawning aggregations, dramatic events where 100s to 1000s of individuals gather annually at specific locations for reproduction. Spawning aggregations are often targeted by local fishermen, making them extremely vulnerable to over fishing. The Red Hind Bank Marine Conservation District located in St. Thomas, United States Virgin Islands, was closed seasonally in 1...
متن کاملEffect of marine protected areas (MPAs) on consumer diet: MPA fish feed higher in the food chain.
Marine Protected Areas (MPAs) are often established to mitigate the effects of overfishing and other human disturbances. In Fiji these are locally managed and, where enforced, have significantly higher coral cover, higher fish biomass, and lower seaweed cover than in the adjacent, unprotected reefs (non-MPAs). We investigated how the isotopic signatures of a common, mid-level consumer, Epinephe...
