Summary
[edit]DescriptionEncroutement algal et ou bactérien aout 2016 "Sèvre niortaise" F.Lamiot.jpg |
Français : Encroutement algal et/ou bactérien photographié en aout 2016 sur le fond de la rivière "Sèvre niortaise", dans une partie peu profonde et bien éclairée, au lieu dit "Pont romain d'Azay-le-Brûlé" (France). Sur ces encroûtements divers invertébrés, dont des gammares et de nombreux w:Theodoxus (Theodoxus fluviatilis probablement) peuvent être observés. Cette section du cours d'eau est riche en zones d'encroutement qui s'y forment généralement à partir de tapis horizontaux de mousses aquatiques (bryophytes) ou de tapis verticaux de Marchantiophyta.
English: Crusting algal and/or bacterial photographed in August 2016 on the bottom of the river "Sèvre Niortaise" in a shallow and well lit place, called "Roman Bridge of Azay-le-Brûlé "(France). On these crusts various invertebrates, including gammares and many w:Theodoxus (Theodoxus fluviatilis probably) can be observed. This section of the river is rich in crusting areas that typically form it from horizontal carpet aquatic of mosses (bryophyta) or vertical carpet of Marchantiophyta. |
