Traps to catch microfauna transported by wind were installed on already colonised by plants area, in the vicinity of the glacier. After 6-week-exposition 859 individuals of microfauna were caught, of which Nematoda constituted 71%, Tardigrada 22% and Rotifcra 7%. Number of microfauna individuals caught depended on distance from the already colonised areas and presence of plant parts, together with which animals can be transported more easily. Microfauna connected with vegetation, which is transferred together with plant parts, was transported in higher numbers. Probably these taxa (i.e. Diphascon within tardigrades and Dorylaimidae within nematodes) colonise new habitats at first, but other species dominate later in freshwater bodies.
Phytophthora cryptogea was isolated from diseased stem base of Aquilegia discolor and rotted leaves of Saxifraga and Sempervivum spp. Additionally, Fusarium species and Botrytis cinerea were frequently isolated from diseased parts of plants. Most of Sempervivum species and cultivars except S. soculiferum were colonized in laboratory conditions by P. cryptogea. The isolates from Alstroemeria aurantiaca, Gerbera jamesonii, Saxifraga arendsii, S. paniculata, Sempervivum arachnoideum colonised houseleek leaves with the fastest spread of necrosis on plant parts inoculated with cultures from Gerbera and S. arendsii. The isolate from S. arendsii colonized 5 species and cultivars of saxifrage as well as Iberis sempervivum, Lavendula angustifolia, Sempervivum sobuliferum and Vinca minor with the slowest development on periwinkle. In laboratory trials isolate of P. cryptogea from houseleek grew on PDA and colonized leaves of that plant at temperature ranging from about 10 to 32.5°C with optimum at 20–30°C.
Phytophthora citricola was isolated from diseased seedlings of European beech and Silver fir taken from the most of surveyed nurseries. Fusarium species, Pythium ultimum and Rhizoctonia solani were also found in diseased plant tissues.Isoates of P. citricola fro mboth plants and additionally from heather and rhododendron colonised leaf blades, needles and stem parts of beech and fir. In greenhouse trials on inoculated 1-year-old seedlings necrosis spread about 2 mm/24 hr on beech stems whereas on fir about 1.5 mm/24 hr.
From Hedera helix and Epipremnum aureum showing necrosis of shoot base spread upwards and on leaves Phytophthora tropicalil was isolated. The species was obtained from ⅞of Hedera and ¾ of Epipremnum diseased shoot and root parts. Additionally, Botrytis cinerea, Fusarium avenaceum and Rhizoctonia solani was recovered from some of affected plants. The chosen 2 isolates colonised petioles and leaf blades of both host plants. P. tropicalis caused necrosis of leaves of 11 tested cultivars of H. helix and 13 other pot plant species and seedlings of tomato. The fastest spread of necrosis was observed on leaves of Peperomia magnoliaefolia, Pelargonium zonale and Phalaenopsis x hybridum. The development of disease was observed at temperatures ranged from 10 to 32.5°C with optimum 30°C.
