DOI: 10.1002/ece3.5234
Abstract: Abstract Population size is generally limited by resource availability during and outside the breeding season. Therefore, maximum size of flocks may provide important information on population regulation and the influence of diet and trophic level… read more here.

DOI: 10.1002/etc.5636
Abstract: In 2019, the Idaho Department of Environmental Quality (IDEQ) implemented a paired surface water and fish tissue data collection program to derive a state-specific bioaccumulation factor (BAF) for inorganic arsenic (iAs) as part of the… read more here.

DOI: 10.1007/s00244-017-0368-y
Abstract: The Glaucous-winged gull (Larus glaucescens) has been selected by Environment Canada as a marine indicator species for long-term monitoring of persistent contaminants in the Canadian Pacific. However, the indicator value of this species depends on… read more here.

DOI: 10.1007/s00244-018-0529-7
Abstract: Penguins are reliable sentinels for environmental assessments of mercury (Hg) due to their longevity, abundance, high trophic level, and relatively small foraging areas. We analyzed Hg concentrations from blood and feathers of adult Humboldt penguins… read more here.

DOI: 10.1016/j.ecolind.2020.106500
Abstract: Abstract Sardines (Sardina pilchardus) and mackerels (Scomber spp. and Trachurus spp.) are amongst the most common fish caught along the Iberian coast for human consumption and, as mid-trophic level organisms, they constitute essential prey in… read more here.

Emergence of negative trophic level-size relationships from a size-based, individual-based multispecies fish model
Sign Up to like & getrecommendations! Published in 2019 at "Ecological Modelling"
DOI: 10.1016/j.ecolmodel.2019.108800
Abstract: Abstract Modeling the mechanisms underlying trophic interactions between individuals allows the food web structure to emerge from local interactions, which constitutes a prerequisite for assessing how marine ecosystems respond to various anthropogenic pressures. Using a… read more here.

DOI: 10.1038/s41598-019-47709-0
Abstract: The long-chain (≥C20) polyunsaturated fatty acid biosynthesis capacity of fish varies among species, with trophic level hypothesised as a major factor. The biosynthesis capacity is largely dependent upon the presence of functionally diversified fatty acyl… read more here.

DOI: 10.1038/s42003-021-02212-z
Abstract: In marine ecology, dietary interpretations of faunal assemblages often rely on nitrogen isotopes as the main or only applicable trophic level tracer. We investigate the geographic variability and trophic level isotopic discrimination factors of bone… read more here.
