Effects of Ingestion of Lithic Particles on Growth of the Apple Snail Pomacea canaliculata (Caenogastropoda, Ampullariidae) [PDF]

open access: yes, 2016
Lithic particles are a common feature in the digestive tract of freshwater snails. Their role in the digestive processes has been demonstrated in some microphytophagous and detritivorous species, as they enhance growth, assimilation and reproduction.

PHYSID SNAILS AS SENTINELS OF FRESHWATER NEMATOMORPHS

open access: yesJournal of Parasitology, 2001
Freshwater nematomorphs, or gordiids, are parasitic as larvae, but free-living in aquatic environments as adults. Studies based on the collection of adults have reported gordiids to be widespread, but discontinuous in distribution. However, a relatively short adult life span and unknown life history make the detection of adults difficult.

Effects of water temperature on summer periphyton biomass in shallow lakes: a pan-European mesocosm experiment [PDF]

open access: yes, 2015
Periphyton communities play an important role in shallow lakes and are controlled by direct forces such as temperature, light, nutrients, and invertebrate grazing, but also indirectly by planktivorous fish predation.
