Population dynamics in benthic invertebrates. A virtual handbook
This book is a compilation of the state-ot-the-art tools for the analysis of population dynamics (growth, mortality, production, consumption, assimilation, respiration) in benthic invertebrates. ItExpand
Food web structure of the benthic community at the Porcupine Abyssal Plain (NE Atlantic): a stable isotope analysis
Generally, within the benthic community at PAP competition for food is reduced by two alternative evolutionary adaptations: (1) specialization on slightly different food sources and (2) vertical expansion of the trophic spectrum. Expand
Consumer-resource body-size relationships in natural food webs.
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. Expand
Stable isotope food web studies: a case for standardized sample treatment
The enrichment of the stable isotopes 13C and 15N across trophic levels is a commonly used tool in studies on organic matter flow and food webs. An accepted standard for pre-analysis sampleExpand
Energy content of macrobenthic invertebrates: general conversion factors from weight to energy
The use of energy-conversion factors based on AFDW is preferable due to their lower dispersion, and a general conversion factor of 23 J · mg−1 AFDW can be used for aquatic macrobenthic invertebrates. Expand
Do Antarctic benthic invertebrates show an extended level of eurybathy
These extended levels of eurybathy in the Antarctic benthos may be interpreted either as an evolutionary adaptation or pre-adaptation to the oscillation of shelf ice extension during the Antarctic glacial-interglacial cycle. Expand
Depth-dependence in stable isotope ratio δ15N of benthic POM consumers: The role of particle dynamics and organism trophic guild
It is essential to marine food-web studies to take into account the general depth effect on POM δ 15 N as well as potential feeding-guild-specific differences in the response of POM consumer tissue δ15 N to avoid serious bias and misinterpretation of stable-isotope-based trophic information. Expand
Growth Performance and Mortality in Aquatic Macrobenthic Invertebrates
A new measure of overall growth performance for benthic invertebrate populations, the index ψ = log(maximum body mass/maximum age) is introduced, which makes growth of populations and species comparable and is likely to be a species-specific feature. Expand
