Description
| - Pakomár Glyptotendipes paripes vykazuje dva rozdílné typy rozšíření v jezerech střední Floridy. V některých jezerech se vyskytuje pouze v minerálním sedimentu při okraji, v jiných v organickém sedimentu ve středu jezer.Organický sediment jezer druhého typu je tvořen z větší části exkrementy pakomárů. Laboratorní pokusy ukazují, že tento sediment podporuje větší populační hustoty a rychlejší růst larev Glyptotendipes paripes. (cs)
- Two opposite distribution patterns of larval Glyptotendipes paripes in relation to organic carbon content in sediments of central Florida lakes were discovered. In a majority of examined lakes, G. paripes larvae were most abundant in sand sediment and their density rapidly declined with increased carbon content (type 1 lakes); however, in some cases the opposite was true (type 2 lakes). To elucidate this anomaly, field-collected organic sediments from types 1 and 2 lakes and sand sediment were studied for G. paripes development in the laboratory. Type 1 organic sediment consisted predominantly of fine particles (<0.25 mm diameter) with low dissolved oxygen levels, whereas type 2 organic sediments consisted primarily of chironomid large faecal pellet aggregates (> 0.25 mm diameter] with significantly higher levels of dissolved oxygen concentrations that were similar to sand sediment. Type 2 organic sediment and sand sediment were conducive to higher survival of G. paripes larvae than...
