  1. Bentické organizmy stojatých a tekoucích vod

  2. Litorál stojatých vod primární produkce Potamogeton sp. - rdest Nymphea sp. - leknín Lemna sp. - okřehek Nuphar sp. - stulík Typha sp. - orobinec FYTOBENTOS MAKROFYTA emergentní submerzní – plovoucí a ponořené Myriophyllum sp. - stolístek Phragmites sp. - rákos

  3. Litorál stojatých vod primární produkce FYTOBENTOS NÁROSTY – řasy, sinice, mechy Tekoucí vody rozsivky ruduchy Diatoma Meridion Batrachospermum Synedra sinice zelené řasy mechy Fontinalis Cladophora Oscillatoria

  4. STOJATÉ VODY - litorál ZOOBENTOS COLLECTORSPREDATORS SHREDDERS Hydrozoa Tulbellaria (Planaria) Hirudinea (Erpobdella, Glossiphonia) Decapoda Odonata Megaloptera (Silais) Heteroptera (Notonecta, Nepa, Gerris, Corixa) Coleoptera (Ditiscus, Gyrinus) Chironomidae (Procladius) Chaoboridae Porifera Oligochaeta (Tubificidae, Naididae) Gastropoda (Lymnaea, Ancylus, Viviparus) Bivalvia (Anodonta, Unio) Isopoda (Asselus aquaticus) Ephemeroptera (Ephemera, Hexagenia, Leptophlebia, Cloëon, Caenis, Ephemerella) Trichoptera (Limnephilidae, Leptoceridae, Polycentropodidae) Coleoptera (Haliplus) Chironomidae (Chironomus, Glyptotendipes) + ostatní Diptera (Ceratopogonidae, Tipulidae) Amphipoda (Gammarus )

  5. Ancylus Tubifex Lymnaea Naididae Porifera Ephemera Asellus Caenis Ephemerella Ditiscus Odonata Lymnephlidae Leptoceridae Chironomidae Nepa Silais Tipulidae Polycentropodidae Gerris Notonecta

  6. ZOOBENTOS STOJATÉ VODY - profundál Dominují OLIGOCHAETA a CHIRONOMIDAE

  7. TEKOUCÍ VODY ZOOBENTOS V horních tocích převládají SHREDDERS v dolních pak COLLECTORS Rychle proudící toky, kamenité dno Shredders: Amphipoda (Gammarusfossarum, G. roeselii) Isopoda (Aselusaquaticus) Plecoptera (Leuctridae, Nemouridae) Trichoptera (Limnephilidae, Sericostomatidae) Coleoptera (Elmidae) Collectors/Grazers Simulidae (Simulium) Chironomidae (podčel. Chironominae/ Orthocladiinae) Trichoptera (Hydropsychidae, Philopotamidae) Ephemeroptera (Heptagenia, Ecdyonurus, Rithrogena, Baetis, Oligoneuriella) Blephariceridae (resp. Filterfeeders) Predators: Trichoptera (Rhyacophilidae, Polycentropidae) Plecoptera (Perlidae, Perlodidae) Chironomidae (Procladius, Prodiamesa)

  8. TEKOUCÍ VODY ZOOBENTOS V horních tocích převládají SHREDDERS v dolních pak COLLECTORS Pisčité a bahnité substráty toku Predators: Odonata (Gomphus, Aeschna, Libellula…) Megaloptera (Sialis) Coleoptera (Ditiscus) Trubelaria Hirudinea (Erpobdella, Helobdella) Heteroptera (Micronecta, Aphelocheirus) Collectors/Gatherers/Filterfeeders Chironomidae (podčel. Chironominae) Limoniidae a Tipulidae Oligochaeta Bivalvia (Unio, Margaritana) Ephemeroptera (Ephemera, Caenis) Grazers: Gastropoda (Dreissena, Pisidium) Coleoptera (Elmidae) Trichoptera (Goeridae) Shredders: Trichoptera (Limnephilidae) Amphipoda (Gammarus)

  9. Rithrogena Rhyacophilidae Nemouridae Perlidae Baetis Perlodidae Leuctra Ecdyonurus Hydropsychidae Simulidae Blephariceridae Limnoniidae Chironomidae Dreissena Micronecta Erpobdella Elmidae Pisidium Aphelocheirus Glossiphonia Unio
