Abundance And Distribution

Abstract Abundance and distribution of nematodes of the genus Trichuris Schrank, 1788 parasitizing domestic sheep (Ovis aries Linnaeus, 1758) were studied in Poltava, Kyiv and Zaporizhzhia Regions of Ukraine. Three species of Trichuris were found, Trichuris skrjabini Baskakov, 1924, Trichuris ovis Abildgaard, 1795 and Trichuris globulosa Linstow, 1901. Trichuris ovis and T. skrjabini were more common (54.9 and 35.7 %), whereas T. globulosa was relatively rare (9.4 %) in the studied material. New species-specific and sex-related morphological characters and metric indices were reviewed as useful in better identification of T. skrjabini, T. ovis and T. globulosa parasitizing sheep.

First Time

Cell morphology and biodiversity of heterotrophic flagellates from soils of the south-eastern part of Khallerchinskaya Tundra were examined for the first time in literature. Species-specific features were analysed, and descriptions of the specie, based on drawings and photos of living cells, are given. The species Cercobodo ovatus Lemmermann, 1910 is transferred to the genus Cercomonas Dujardin, 1841.

Restriction Site Polymorphisms

Variation in the chloroplast genome of 44 accessions representing 14 Eucalyptus L'Hér. species from the series Viminales (sensu Pryor and Johnson 1971) was investigated. Southern analysis of the chloroplast genomes restricted with 12 enzymes revealed 20 restriction-site polymorphisms of which 7 were autapomorphic to individual trees. The 13 informative restriction-site polymorphisms were distributed between individuals of different species, but none was species-specific. Fourteen chloroplast haplotypes were identified for south-eastern Australian individuals. In endemic Tasmanian species, five haplotypes were identified. Chloroplast haplotypes appear to have a mosaic distribution in south-eastern Australia, more closely associated with geographical regions than with morphological species boundaries. The biogeographic distribution of chloroplast haplotypes may be explained by a combination of interspecific hybridisation and introgression, and convergent evolution. The lack of species-specificity of cpDNA variation indicates that, although cpDNA is not appropriate for species-level phylogeny analysis in the series Viminales, it may provide useful information in studies of biogeography and gene flow in Eucalyptus.

Although the use of electron microscopy and its varied methodologies is not usually associated with ecological studies, the types of species specific information that can be generated by these techniques are often quite useful in predicting long-term ecosystem effects. The utility of these techniques is especially apparent when one considers both the size range of particles found in the aquatic environment and the complexity of the phytoplankton assemblages.The size range and character of organisms found in the aquatic environment are dependent upon a variety of physical parameters that include sampling depth, location, and time of year. In the winter months, all the Laurentian Great Lakes are uniformly mixed and homothermous in the range of 1.1 to 1.7°C. During this time phytoplankton productivity is quite low.
