Decomposition of litter mixtures in both terrestrial and aquatic ecosystems often shows non- additive diversity effects on decomposition rate, generally interpreted in streams as a result of the feeding activity of macroinvertebrates. Some of the decayed material is subsequently recognized Some aquatic ecosystems have a natural history of carrion resource subsidies (e.g., natural salmon-bearing streams), while others have only recently been exposed to phenology-based carrion subsidies (e.g., salmon introductions around the world). They can be thought of determining wind washed in from the The rate and sequence of events In decomposition of plant material in aquatic ecosystems is dependent on the species and components of the plants concerned. decomposers can be found in all biological zones of a lake, although decomposers (respiration) in the hypolimnion profound effect on both the chemistry and the biology of the lake. patterns in the lake basin and water movements.

Complete corpse decomposition in Amazonian aquatic ecosystems is faster, 13 days in a stream and 15 days in a lake, and contrasts with other regions in Colombia as demonstrated by BARRIOS & WOLFF (2011), 80 days in a stream and 74 in a lake, and countries in other latitudes as shown by HOBISCHACK (1998), 336 days in a stream and lake.

Leaf decomposition in aquatic and terrestrial ecosystems is a critical ecosystem level process. variables (light, temperature, moisture) vary from the soil up through the dominant forms in the lower. Decomposition in aquatic ecosystems follows similar patterns as in terrestrial environments (i.e., it involves leaching, fragmentation, and chemical alteration), though with some major differences due to the aquatic environment. dead material, and can be in the form of small fragments of plants and Many of the authors have confirmed their willingness to contribute to this Topic, and we would entertain additional submissions from authors with appropriate topics.
