Macrophyte

Abstract: A review of various aspects of invertebrate-microbial interactions is presented. Food resources of stream invertebrates are distinguished by particle size (detritus), the presence of chlorophyll (periphyton), and high protein content (macrophytes). Invertebrate functional feeding groups such as shredders, collectors, scrapers, piercers, and predators are discussed. The interactions between temperature and quantity and quality of stream macroinvertebrate food resouces are described. Symbiotic relationships between stream invertebrates and microorganisms are discussed.

Abstract: A comparison of western Aleutian Islands with and without sea otter populations shows that this species is important in determining littoral and sublittoral community structure. Sea otters control herbivorous invertebrate populations. Removal of sea otters causes increased herbivory and ultimately results in the destruction of macrophyte associations. The observations suggest that sea otter reestablishment indirectly affects island fauna associated with macrophyte primary productivity.
