Information
Ecological parameter: food according to Tachet
Parameter group: life & body related parameters
Explanation:
This trait describes the feeding preference of a species. Nine categories are defined. Invertebrate food may be composed of detrital organic (mainly vegetal) material, with a variable proportion of fine mineral elements and microorganisms. This material is separated according to particle size in three categories. Dead animal material is included in a specific category. Food may be also composed of living organisms. Living microphytes (sensu lato, e.g. diatoms, hyphomycetes) are distinguished from macrophytes (e.g. filamentous algae, bryophytes, Dycotyledones) and microinvertebrates (e.g. meiofaunal crustaceans) and finally from both macroinvertebrates and vertebrates (e.g. fish eggs or larvae).
