Abstract:

Morphometric variability was studied in Prionchulus punctatusand Clarkus papillatus from closely related forest sites: Site 1 (eutrophic to calcic mull humus), site 2 (contiguous tosite 1, eutrophic mull humus with amore or less leached soil), site 3 (acid mull humus), site 4 (located in site 3 but just under the crown of an old oak, moder humus), site 7 (moder humus, developedin a wide area). Results from correspondence analysis for both nematode species from site 2 suggested two distinct population types (a) with small individuals (Pp: 1.85 ± 0.05 mm and 87.2±5.7 μm for body length and tail length respectively; Cp: 1.11±0.02 mm and 78.5±1.9 μm)with typical characteristics of populations collected from acalcic mull and (b) larger individuals (Pp: 2.14 ± 0.04 mm and 100.2 ± 1.8 μm for body length and tail length respectively; Cp:1.21±0.01 mm and 83.3±2.2μm) similar to populations collected from an eutrophic mull. Results from correspondence analysis from site 4 showed that the populations of the two species had intermediate characteristics between populations collected from a mull humus and from a moder humus. Moreover, a laboratory culturing experiment with adult Clarkus papillatus collected from site 3 and cultured on three humus forms (calcic mull, site 1; acid mull, site 3; moder, site 7) showed that this species reproduced successfully on mull acid only. The conjunctural or the structural influence on morphometric plasticity of these species is discussed from a functional ecology aspect.
