- A number of studies have examined patterns of body size distribution in benthos across or within systems, with little consensus toward general principles.
- In this study, we examine how the size structure of benthos in lakes and predation by fishes were related over five years under seminatural gradients of fish biomass and predation pressure in three north-temperate experimental lakes.
- The presence of other specialized benthos at the crinoid-bearing localities indicates that the ocean bottom locally was not fully anoxic.
Derivatives adjectiveˈbɛnθɪkˈbɛnθɪk Ecology New coastal ocean remote sensing techniques permit benthic habitats to be explored with higher resolution than ever before. Example sentencesExamples - There is no escape for the benthic epifauna in space or time-they must be grazer resistant.
