Microannelids (Enchytraeidae, Naididae, Parergodrilidae) along a 4000 m Afrotropical elevational gradient on Mount Cameroon

Popis výsledku v původním jazyce

Knowledge of the enchytraeid fauna in sub-Saharan Africa is limited to a few specimens collected during the 20th century, often described as new species. No quantitative data or records of other annelids within the soil mesofauna have been reported. Addressing this gap, we studied species diversity, densities and biomass of soildwelling microannelids across a wide range of habitats. In 2013, during the transition from the wet to dry season, we sampled an elevational gradient on Mount Cameroon from coastal lowland rainforest, through montane forests and savanna, to Afroalpine grassland at 4000 m a.s.l. (11 elevations, 3 sites each). Specimens obtained by wet funnel extraction were counted, measured and identified based on morphological characters (molecular barcoding of some). Biomass was assessed based on the body length : volume ratio. The obtained 357 specimens represented approximately 16 enchytraeid species (many yet to be described) from 6 genera (Buchholzia, Enchytraeus, Fridericia, Hemienchytraeus, Henlea, and Xetadrilus), Pristina cf. jenkinae (Naididae) and the polychaete Parergodrilus cf. heideri (Parergodrilidae). The latter was recorded for the first time in Africa and in the tropics. Mean microannelid densities varied from 0 in the savanna at 3100 m a.s.l. to 4178 +/- 875 individuals per square metre (+/- SE) in Afroalpine grassland at 4000 m a.s.l., where also the highest biomass, 0.88 g dry weight per square metre, was reached. Whereas species richness was considerable, densities were comparable to the few tropical sites for which data have been published but much lower than those often found in colder climates.
