Switches between zoophagy, phytophagy and detritivory
of Sarotherodon mossambicus populations in twelve Sri Lankan lakes.
is a frequent feeding habit among Loricariidae species and has been considered as a specialised behaviour related to the morphological adaptation of the digestive system (mouth shape and position and intestine length).
In other reports of dry season increase in diet overlap the situation is different due to a decrease in feeding rates of a switch to detritivory
(e.g Lowe-McConnell 1964, Prejs and Prejs 1987).
The rapid growth of Asynarchus larvae, which is in part facilitated by an ontogenetic shift from detritivory
to carnivory (including other caddisflies as prey) enables this species to complete larval development, pupate, and emerge before vernal and autumnal habitats dry (S.
Energetics of detritivory
and microbivory in soil in theory and practice.
Flow of energy and materials among these "peripheral" components is governed by trophic links, such as herbivory, detritivory
, predation, or omnivory [ILLUSTRATION FOR FIGURE 1 OMITTED].
Omnivory may be a key to the dominance of red crabs on Christmas Island where they straddle three trophic levels: detritivory
, herbivory, and carnivory (O'Dowd and Lake 1989, 1990, 1991, Lake and O'Dowd 1991).
