Herbivorous flies, all Tephritidae, contained lower N concentrations than predaceous or detritivorous
flies after considering body mass.
In addition to arachnids, the cave-dwelling fauna includes vertebrates of many other groups, such as annelids, molluscs and insects, but they are always detritivorous
or decomposer organisms, as the total darkness prevents plant growth and thus the existence of plant-eating animals.
This link could be attributed to enrichment of microbial biomass coupled with enhancement of nutrients of the decomposing leaves, required for diet of the detritivorous
fish (Rajendran & Kathiresan 2000, 2007).
Our findings support Cummins' (1974) early speculation that detritivorous
macroinvertebrates derive much of their carbon from microbes in streams (the so-called "peanut butter"), instead of from the detritus itself (the "cracker"), but we add that exopolymers may strengthen this bacterial-invertebrate trophic link.
This occurrence originated many micro-habitats and the enlargement of ecological niches for macroinvertebrates, because the decomposition detritus released provided food resources for the detritivorous
The energy availability and nutrient cycling need to be elucidated; since the detritivorous
species are abundant, in number and biomass.
The azotobacters which enrich nitrogen in the decomposing mangrove leaves may be a major factor in determining the palatability of detritus food to detritivorous
animals like prawns.
One exception to the potential generality of the low N:P ratio of fish excretion is in systems with dense populations of detritivorous
or herbivorous fishes that feed on low-P food (e.g., Brabrand et al.
Oreochromis niloticus is a detritivorous
species in the Barra Bonita reservoir, since the detritus was constant in the diet of almost all size classes.
The former species is omnivorous, and latter is detritivorous
, both species feed on the reservoir's substrate that observes alternation may be a strategy to avoid competition.
Many species of derelomine flower weevils have adults which function as pollinators and predominantly detritivorous
larvae that do not attack the infructescences or seeds of their host plants.
A prawn (Caridinia nilotica) has filled the detritivorous
niche once occupied by 13 species of furu, and a sardine (Rastrineobola argentea) has taken the place of more than 20 species of planktivorous furu.
