Studies on taxonomic position of <em>Pinus uliginosa</em> Neumann, <em>P. uncinata</em> Ram. and <em>P. mugo</em> Turra, indicate a significant specificity of <em>P. uliginosa</em> population from Wielkie Torfowisko Batorowskie Peat Bog. <em>Pinus uncinata</em> in respect of genetic similarity is close to <em>Pinus mugo</em> Turra populations from the Tatra Mts. The time of divergence of <em>P. uliginosa</em> from the common ancestor, taking into account Nei's genetic distances, is twice as long as in the case of <em>Pinus uncinata</em>. In the view of the results the supposition that <em>Pinus uliginosa</em> from Wielkie Torfowisko Batorowskie Peat Bog is a marginal population of <em>P. uncinata</em> can be excluded, because of their significant difference in genetic structure. The presumable reasons of specificity of <em>P. uliginosa</em> population are disscused.

The taxonomic position of the population of tree-like, mostly polycormic individuals of pines from the Mshana peat bog in the Gorgany Mountains (East Carpathians, Ukraine) has been studied on the basis of the morphological characteristics of cones and needles, and anatomical characteristics of the needles. These features have been compared with the surrounding <em>Pinus mugo</em> population as well as <em>P. uliginosa</em>, <em>P. mugo</em>, <em>P. sylvestris</em> and <em>P. uncinata</em> from natural populations of the taxa. Tree-like individuals were found to have the most similar needles to <em>P. uliginosa</em>, but most similar cone characteristics to <em>P. mugo</em>. It was concluded, that the tree-like population has a relic character and can present the trace of the early migration of <em>P. uliginosa</em> from the West and its hybridisation with <em>P. mugo</em>.

Present study aimed at determining genetic structure of the <em>Pinus mugo</em> Turra population, growing at a peat bog, on Ostry Wierch slopes in the High Tatra mountains, in respect to the number of genotypes present in the population, and at defining variabilities of morphological and anatomical traits. In the examined plants, isoenzymatic analysis demonstrated existence of only two genotypes (A and B), which formed relatively vast clones. Mathematical-statistical analysis of 13 anatomical - morphological traits of the needles proved that the examined clump consisted of two clearly distinguishable groups, corresponding to the two earlier electrophoretically identified clones A and B. The obtained data allowed to conclude that the method based on anatomical-morphological measurements may, at least in some cases, permit identification of <em>Pinus mugo</em> clones

Biometrical Study

Sixteen individuals were sampled for study of variation in 17 anatomical and morphological characters. Only individuals of low polycormic growth (trait typical for <i>Pinus mugo</i> Turra) connected with incurved one-year-cone stipes (a similar situation exists in <i>Pinus sylvestris</i> L.) were chosen, thus the sample studied cannot be treated as a random one. It has been shown by multivariate statistical analysis that these 16 individuals are quite different from each other, Mahalanobis'generalized distances between them being nearly 50% significantly different from 0. The sample studied in this respect is distinctly different from pure stands of both putative parental species (i.e. <i>Pinus mugo</i> and <i>P. sylvestris</i>). Every plant studied shows a different combination of traits typical (or nearly typical) for both the above-mentioned species and traits that are truly intermediate between them. The results support the frequently expressed opinion that the mountain pine population from the peat bog "Bór na Czerwonem" is, in fact, a hybrid swarm formed by hybridization between <i>Pinus mugo</i> and <i>Pinus sylvestris</i>.

Abstract The main aim of this study was to describe the variation between the populations of the dwarf mountain pine Pinus mugo Turra based on the morphological and anatomical traits of their needles, and to investigate the relationship between the observed variation and environmental conditions (altitude and substrate). Two-year-old needles were collected from 180 individuals of six populations of P. mugo growing in the Tatra Mts. Two populations were classified as dense, located at 1360–1450 m altitude, and the remaining four formed loose clusters and were situated at 1500–1650 m altitude. Four of the populations are growing on granite and two on a limestone substrate. The natural variation of 10 morpho-anatomical and 3 synthetic needle traits was measured. In addition to descriptive statistics, the analyses of variance (ANOVA) with a Tukey test and principal component analysis were computed. We also estimated Pearson correlation coefficients for the examined needle traits and altitude as well as substrate. Our results indicate that the P. mugo populations differ significantly with regard to the investigated traits for which the Trzydniowiański Wierch population was the most distinct. The observed pattern of variability is largely caused by differences in stomatal traits and these features are positive correlated with altitude. Additionally, populations growing on granite have larger values for most of the examined traits compared to populations growing on limestone.

Erythrocyte nucleotide concentrations were surveyed among 20 inbred strains of mice in order to further assess the variability in GTP concentration. There was no significant difference in erythrocytic ATP concentration (Scheffé's test at P = 0.01), 678-1154 nmol/mL packed cells, among the strains surveyed. Two groups were distinguishable with respect to erythrocytic GTP concentration, 8 strains having high GTP, 215 ± 44 nmole/mL packed cells, and 12 strains having low GTP, 34 ± 12 nmole/mL packed cells. The erythrocytic GTP concentration determining trait Gtpc was previously shown to be linked to transferrin, Trf, on chromosome 9. Analysis of 232 [(B6 × WB) F1 × B6] backcross individuals for Gtpc and 8 microsatellite markers restricted the localization of Gtpc to a 5.6 ± 2.1 cM region. The gene order and genetic distances in cM ± SE are: (D9Mit14) 0.4 ± 0.4 (D9Mit24) 1.7 ± 0.8 (Gtpc, D9Mit51, D9Mit116, D9Mit212) 3.9 ± 1.3 (D9Mit200) 3.0 ± 1.1 (D9Mit20) 7.8 ± 1.8 (D9Mit18). The GTP concentration determining trait appears to be a property of erythrocytes as no differences were observed for GTP/ATP ratios of brain, kidney, liver, and tongue from a low GTP strain, C3H/HeHa × Pgk-1a and a high GTP strain, C57BL/6J.Key words: Gtpc, guanosine-5'-triphosphate, GTP, mouse, chromosome 9.

Abstract Results of artificial fertilization of P. uliginosa with P. sylvestris and P. mugo are presented and discussed. P. sylvestris and P. mugo are thought to be the parental species of P. uliginosa. Two grafts of one P. uliginosa clone from Arboretum of the Institute of Dendrology in Kórnik, Poland were used as mother individuals. One individual of P. sylvestris and one individual of P. mugo were the pollen donors. Three mature cones were obtained as the result of artificial pollination of P. uliginosa with P. mugo pollen. Out of 107 seeds, 68 were filled what gives 63%. P. uliginosa conelets pollinated with P. sylvestris pollen were all aborted. Based on obtained data, close phylogenetic relationship between P. uliginosa and P. mugo complex is suggested.

The taxonomic position of the West African Negeta semialba Hampson, 1918 is revised and the species is transferred from the genus Negeta Walker, 1862 of Westermanniinae to Leucobaeta László, Ronkay & Witt, 2010 of Nolinae: Leucobaeta semialba (Hampson, 1918) comb. n., based on morphological analysis. The hitherto unknown male adult and genitalia of both sexes are described and illustrated. Leucobaeta semialba is compared to the superficially similar Afrotropical Negeta mesoleuca (Holland, 1894) and N. ruficeps (Hampson, 1902); two sibling species from East Africa and Madagascar are described as new to science: L. smithi and L. malagassa spp. n. Pairwise genetic distances of COI-5P sequences between the taxa are provided.

During a survey of the freshwater aquatic diatom flora of two peat bog areas in Tierra del Fuego, southern Argentina, a new taxon belonging to the genus Stauroneis that could not be identified was observed. Based on detailed light and scanning electron microscopy observations and comparison with similar larger-celled Stauroneis species worldwide, the taxon is described as new: Stauroneis fuegiana Casa & Van de Vijver sp. nov. Stauroneis fuegiana can be distinguished based on the slightly raised marginal crest, the typical broadly lanceolate valve outline with subrostrate apices, the almost rectangular central area and its valve dimensions.Comments are made on its taxonomic position and how the new taxon can be distinguished from other larger-celled Stauroneis species. Brief notes on the ecology and distribution are added.
