The „Golczewskie Uroczysko” nature reserve was established on 5 May 2004 to protect the raised peat bog and the dystrophic Lake Żabie with its surrounding transitional bog and adjacent forest complexes containing valuable plants. In May, July and October 2006 the research of odonates (Odonata) fauna has been conducted in this area. A total of 575 odonates individuals belonging to 29 species (366 imagines, 152 larvae, 57 exuviae) were collected and among these 489 specimens belonging to 28 species were collected in Lake Żabie, 26 specimens belonging to 7 species on the beat boog, 52 specimens belonging to 3 species in flooded alder forest and 8 specimens belonging to 2 species were collected in ditches in the forest. The eurytopic species were dominated with substantial parts of tyrphobiontic and tyrphophilous species.

The „Golczewskie Uroczysko” nature reserve was established on 5 May 2004 to protect the raised peat bog and the dystrophic Lake Żabie with its surrounding transitional bog and adjacent forest complexes containing valuable plants. In May, July and October 2006 the research of water mite (Hydrachnidia) fauna has been conducted. A total of 557 water mite specimens belonging to 41 species were collected and among these 382 specimens belonging to 31 species were collected in Lake Żabie, 83 specimens belonging to 21 species were collected in ditches in the forest, 70 specimens belonging to 15 species in a ditch on the beatboog and 22 specimens belonging to 10 species in flooded alder forest. In a ditch in the peat bog, ditches in the forest and Lake Żabie tyrphobiontic and tyrphophilous species were dominant, with a substantial part of small water body species in Lake Żabie and with similar part of small water body species and vernal astatic water body species in a ditch in the peat bog and ditches in the forest. In flooded alder forest vernal astatic water body species were dominants.

Rumex drummondii Meisn., a south-western Australian endemic vascular plant species recorded from widely separated localities, had not been collected for 46 years and was considered possibly extinct. The methods developed from search theory, which has been used for finding lost people or objects, were applied to finding R. drummondii, starting from previous records. Eleven populations of the species were discovered within a 50 km radius in the Kalgan River and Manypeaks region. A disjunct population of six plants was found in 1992 in a parking area at a crossing of the Moore River, 480 km north north west of the others, but had disappeared by 1994. Surveys in the Gingin Brook and Moore River region and between Kalannie and Kulja, another disjunct record, failed to find further plants. The species occupies temporarily wet depressions, lake edges and roadside excavations and dam edges protected from grazing by sheep; habitats also occupied by congeneric weedy species. The species occurs on road verges and farmland and is known from one nature reserve. The rediscovery of R. drummondii enables it to be included in the assessment of potential biological control agents for related weed species in the genera Emex and Rumex.

The first electron-microscopic investigation of silica-scaled chrysophytes in water bodies of the protected area Kurgalsky Nature Reserve located in the North-West of European Russia has resulted in the discovery of two species that are new for the Russian flora, Mallomonas favosa and M. teres. Mallomonas teres is reported for the first time since its original descriptions. In addition, Paraphysomonas cf. ovalis and an unknown species of Mallomonas were observed. Descriptions, original photos, and habitat features of these four species are given.

AbstractAn account is given of chrysophycean stomatocysts and algae occurring together with the carnivorous plants known as bladderworts, Utricularia intermedia, U. minor and U. australis, in the peat bog of Jeleniak-Mikuliny Nature Reserve. Eleven chrysophycean stomatocyst morphotypes were found, all reported for the first time from this nature reserve. Among them, two are new records for Europe (stomatocysts 330 and 208) and another two are new for Poland (stomatocysts 112 and 387). Descriptions are provided together with SEM illustrations. General data about cyanobacteria and eukaryotic algae occurring with these stomatocysts are enumerated.

Estuarine Gradient

The northern Galician rias provide important economic and social services from fisheries, shellfish harvesting and recreational activities. Consequently, these rias have been included in the Nature 2000 Network as a Special Conservation Zone. The aims of this study were to describe the meiofauna spatial structure in terms of diversity and abundance of major taxa, as well as its relationship with the environmental characteristics in the Ria de Foz nature reserve. For this aim, environmental gradients and distribution patterns of intertidal meiobenthic communities at the Ria de Foz nature reserve were studied using multivariate methods. Ria de Foz showed to be a complex transitional habitat with significant changes in its environment along the estuarine gradient. An abundant and rich meiofauna community was reported at Ria de Foz. A total of 21 higher taxa of meiofauna were found. The most common taxa were nematodes, copepods, ostracods and turbellarians. Three clear different meiobenthic communities were defined. These three communities showed a clear spatial distribution pattern along the estuarine gradient. Moreover, a high degree of similarity between distribution patterns of meiobenthic communities and previously studied macrobenthic communities was found. Regarding the role of environmental factors shaping meiobenthic community distribution patterns distance to the river mouth was the environmental variable that best explained meiobenthic community structure and distribution. Therefore, changes on hydrodynamics that affect environmental factors related to the estuarine gradient will change the distribution pattern and diversity of benthic communities. This work provides the first information about meiobenthos diversity and structure in the Ria de Foz nature reserve and should be useful for future management and conservation plans on this and other similar protected areas.
