Abstracts |
Laboratory and field observations were undertaken in the Kampinos Forest, near Warsaw (the Mazowsze region), and in the Piska Forest, in Mikolajki (the Mazurian Lakeland) from spring to autumn 2004 to investigate the probable causes and results of the success of small balsam (I. parviflora) in Poland. Using a steel soil corer, samples of 10 cm2 in surface area and 10 cm depth were taken from each site 3 times a season (before flowering, during flowering and at seed maturity). Springtails (Collembola) and mites (Acari) were extracted from soil cores using a Tullgren apparatus. The arbuscular mycorrhizal status of both species was also investigated. In summer 2004, an assessment of the presence of population of netted carpet moths was made in all known and surveyed sites for yellow balsam (Impatiens noli-tangere) in Piska Forest. Seed productivity of small balsam and yellow balsam was calculated only in the Mazurian Lakeland. Population crashes of yellow balsam in the Mazowsze region may linked to this species being particularly prone to attack by fungal pathogens. Important fluctuations in the size of yellow balsam population in the Piska Forest had also been associated with the presence of the endangered netted carpet moth. Compared with small balsam, yellow balsam also accumulated more soil mesofauna. Arbuscular mycorrhiza symbiosis is typical of both small and yellow balsam, but there were differences between the diversity of mycorrhizal fungi in the roots of both species in both the Kampinos Forest and the Piska Forest. The situation may be connected with an increase in root colonization by dark septate endophytic fungi, which is generally observed in cold-stressed environments in the Mazurian Lakeland. |
