On the other hand, Diporeia is a passive detritivore
and has access to phytoplankton mostly in the spring when conditions favor material settling to the bottom.
(n) Percentage of total fish captured that were detritivores
held in artificial streamside channels were food limited (Richardson 1991), and higher levels of coarse particulate organic matter (CPOM) loading resulted in higher densities of collectors feeding on fine particulate organic matter (FPOM, Richardson and Neill 1991).
In terms of trophic roles, two species were detritivores
, 11 species were herbivores, 13 were predators, four were scavengers, which may also be predators or detritivores
, and six species were suspension feeders.
Arthropods are the most abundant herbivores and detritivores
(Seasted and Crossley, 1984) and influence the productivity of plants, the cycling and the nutrient flow in terrestrial ecosystems (Crossley, 1977; Mellec et al., 2011).
We also analyzed the specimens classified among the high faunistic values (super-dominant, dominant, super-abundant, very abundant, abundant, super-frequent, very frequent, frequent, and constant), and we found 22 (8 predators, 5 omnivores, 5 detritivores
, and 4 herbivores) and 10 (5 predators, 3 omnivores, and 2 herbivores) species for organic and conventional systems, respectively.
Organisms were classified into functional groups based on ecological processes that involve soil fauna: soil engineers = ants, earthworms, Isoptera; detritivores
= Dermaptera, Diplopoda, Coleoptera, Blattodea, Isopoda, Acari, Diptera; herbivores = Hemiptera, Orthoptera, Lepidoptera larvae, Mollusca, Phasmatodea; and predators = Araneae, Chilopoda, Opiliones, Pseudoscorpionida, Mantodea.
This study investigated the occurrence of morphological and immunohistochemical alterations in the branchial tissue of two fish species--Plagioscion squamosissimus (Heckel, 1840), a carnivore, and Lithodoras dorsalis (Valenciennes, 1840), a detritivore
which were used as biomarkers for environmental impacts.
Individual and joint actions of selenate and methylmercury on the development and survival of insect detritivore
Megaselia sclaris (Diptera: Phoridae).
Leaf Litter Selection by Detritivore
and Geophagous Earthworms.
The functional groups were the following: herbivore, detritivore
, predator, parasite, omnivore, non-feeding, and unknown.
Filter feeder; possible detritivore
; lakes, rivers, canals, irrigation ditches; usually slow flow; warm to cool waters; in ID, mostly in Snake River (lower to middle), often on soft substrate; often abundant.
