A shift in the trophic structure of assemblages of soil nematodes in a Central European woodland – an indication of a forest maturing or climate warming?

Original language description

Soil nematodes were studied in oak-hornbeam, oak and beech climax forests in the Protected Landscape Area and Biosphere Reserve Křivoklátsko in Central Bohemia, Czech Republic. This study was carried out in the years 1994–1995 (Period 1) and 2006–2007 (Period 2). In Period 1 the mean total precipitation per year was 664.5 mm and mean air temperature 8.4 °C. In Period 2 these values were 449.0 mm and 9.0 °C. The abundance of root-fungal feeders, fungivores (F) and bacterivores (B) were significantly greater in Period 2 than in Period 1. The abundance of plant parasites (PP), omnivores, predators and insect parasites did not differ significantly between the two Periods. Shannon diversity index H’gen significantly decreased as a result of abundant microbivore populations in Period 2. The values of PPI significantly decreased because of a high abundance of Filenchus and some reduction of PP with c-p values greater than 2. (B+F)/PP ratio significantly increased in Period 2 because of a significant increase in the abundance of B and F. No significant differences between the two Periods were found in the values of the Maturity indices, NCR, EI, SI, BI and CI, indicating no deterioration in nematode assemblages. Principal Component Analysis of genera revealed that although the composition of nematode assemblages in individual forests overlapped the samples from Period 1 and Period 2 were in two separate groups. Very likely, warmer andndrier years caused the changes observed in nematode assemblages but they could also result from natural long-term variations in climax systems. The abundance of Tardigrada was significantly higher in Period 2.
