Classification of phenotypic variability in forest dwelling arthropods, especially in applied bioindication, remains difficult due to the complex and synergic ecological interactions. Ecologically, it corresponds with the concept of alternative ontogenies in order to maintain high population fitness. The research on the geobiont Haplothrips subtilissimus (Thysanoptera: Phlaeothripidae) morphometric plasticity alongside selected ecological gradients (temperature, humidity, food availability) and the environmental impact in the xerothermous hilly oak wood (MartinskY les, SW Slovakia), have revealed that (MAN(C)OVA and Kruskal-Wallis test) the head width (p < 0.001) and anterior pronotum width (p <= 0.002) as the only statistically significant variables. The Kruskal-Wallis test (non parametric ANOVA) revealed significant variation (more noticeable in males) in ecologically more diverse ecotone stands. A significant correlation (p < 0.001) could be shown between the morphometric parameter pairs head width and anterior pronotum width for both sexes (0.729 for females and 0.822 for males) and between anterior and posterior pronotum width only for males (0.859). Pillai's statistics revealed an interaction of soil humidity and soil temperature which confirms female body parameters depend on habitat conditions (p = 0.011). Females responded mainly to soil temperature (p = 0.018) and food availability (p = 0.030). Soil humidity interacts with the male's morphology (soil humidity p = 0.040), while the relationship to food availability (Acarina) was not statistically significant (p = 0.350). No body parameter has been significantly affected by environmental stress. (C) 2016 Elsevier Ltd. All rights reserved.
