Geographic variation is one of the most intensively studied bird song topics. However, our knowledge of geographical song variations in most species studied so far is very sparse, with many areas of the species-typical geographic distributions still unexplored. One striking example is the Yellowhammer: for this species most song studies have been conducted along well defined dialect borders, but almost nothing is known about its song characteristics in other regions of its broad geographic distribution. In this study, we investigated the song structure variations and stereotypes in different areas of western Belgium and northern France. We described 66 different song types (а-elements) in 45 males recorded. Each male had a unique individual repertoire consisting of 1 to 4 of these song types. This high variability at the individual level contrasted with the high homogeneity of the specific repertoire over the whole geographic distribution of the species. The evolutionary implications of such specificity are discussed with regard to song learning and timing of singing activity. Finally, all males recorded belonged to the western regiolect, although some mixed- singers were also recorded. These results contrast with the very few studies previously conducted in western Europe which have suggested that eastern regiolect songs were common in this geographic area.

The aim of the paper is to present the approach to the application of the graph clustering algorithm to the recognition of geotechnical layers from the dilatometer tests. Results of the measurements obtained from the DMT test in the test site (subsoil of one of the buildings in the Warsaw University of Life Sciences campus) were analyzed by the clustering algorithm which was able to extract the separate groups of the measurements, representing identical soil type. This method is parameterized, so its verifi cation by the geotechnical experts was necessary to determine the optimal parameter values. They lead to the determination of the soil types as close to the actual situation, as possible. Also, the output of the algorithm was analyzed by the geotechnical experts to identify and label the extracted soil types.

The diagnosis of acute myeloblastic leukaemia (AML) is based on cell morphology, cytogenetic and molecular changes, cell markers and clinical data. Our aim was to establish whether morphology and cell markers are comparable in the evaluation of AML. Bone marrow smears were analysed, and flow cytometry and monoclonal antibodies were used to determine cell type and maturity. Morphology and cell markers correlated differently in different AML subtypes.

Recently the significance of genetic traits, influencing hormonal and environmental factors, in susceptibility to osteopenia and osteoporosis development has been indicated. Much attention to the polymorphic variants of vitamin D receptor (VDR) gene was paid. The restriction polymorphisms in VDR gene could be involved in the modulation of vitamin D action. The VDR polymorphism influence level of bone mineral density (BMD) and cause the osteopenia and osteoporosis.124 postmenopausal women with osteopenia have been analysed (mean age 58.4±5.9 years). For detection of Taq\ VDR polymorphism PCR/RFLP (polymerase chain reaction/restriction fragment length polymorphism) assay have been used.The higher prevalence of 77" genotype (44.4?ó) in investigated group of postmenopausal women has been determined. The mean weight, height and BMI were the lowest in the TT group and the shortest time since last menopause in this group has been observed. In TT group the lowest BMD level and f-score value was determined (0.939 g/cm- and -2.18, respectively). The same observation we have found if comparing the young adults (YA) (78.3°o) and age matched (AM) (88.1°o) index (Tab. 1). The slight tendency to lower age of last menopause in the group of women with genotype containing at least one Tállele (TT + Tí) 49.5±4.2 vs. 50.9±3.8 years has been detected. The presence of Tállele of VDR polymorphism could predict the lower bone mineral density and ¡-score value and connect with early occurrence of last menses in the group of postmenopausal women. For founding a clearly correlation between TaqI polymorphism and appearance of osteopenia and osteoporosis further investigations are necessary.

Gasteria has ovular incompatibility, and recognition of cross- and self-pollen takes place. Cross-pollination includes recognition and pistil activation and leads to seed set. Self-pollen germinate, and their pollen tubes penetrate the ovules but after fertilization they abort. A group of glycoproteins in the pollen coat seems implicated as signal molecules for recognition and activation. Pistil activation is expressed as extra water uptake in the pistil, especially in the fluid pollen tube pathway, and results in higher in vitro pollen tube penetration in the ovular micropyle. In the fluid pollen tube pathway of unpollinated styles a high concentration of sucrose, glucose and fructose is present. The level of these carbohydrates remains the same during the pollen tube growth of cross-pollen. This level decreases after the passage of self-pollen through the stylar channel, and the level of carbohydrates is restored. This implies extra carbohydrate influx in the pollen tube pathway after cross-pollination. Recognition and activation signals act together after cross-pollination of Gasteria. After self-pollination the utilization of carbohydrates lowers the pistil’s carbohydrate capacity, perhaps also leading to a late-acting incompatibility.

In the spathebothriidean tapeworm Didymobothrium rudolphii (Monticelli, 1890) the fine structure of the vitellocytes at different stages of their development within the vitelline follicles, vitelline ducts and uterus was studied for the first time using transmission electron microscopy. The vitellocyte inclusions of D. rudolphii are shell globule clusters containing tightly packed shell globules associated with a matrix of moderate electron density, glycogen granules, large electron-lucent lipid droplets (up to 3 μm in diameter), and, occasionally, a lipid droplet may occur in the nucleus of the vitellocytes. The diameter of the clusters ranges from 0.4 to 2.5 μm, the number of shell globules in the clusters varies from 8 to 45, and the size of the globules ranges from 0.12 to 0.25 μm and they are of approximately homogeneous sizes within a cluster. Most vitellocyte lipid droplets have a heterogeneous configuration with a ‘cavity’ inside them when they are within vitelline ducts and intrauterine eggs. Vitellocytes of the eggs contain dark concentric bodies and lipid droplets. The interstitial tissue has a syncytial structure. The morphological parameters of the diameter and shape of shell globule clusters, arrangement of shell globules in clusters, number and diameter of globules within clusters, types of lipid droplets and presence of dark concentric bodies are compared with those of two other spathebothriidean genera, Cyathocephalus and Diplocotyle. The comparative data demonstrate that vitelline material morphology has unique features in three spathenothriidean genera and may be used as evidence for the recognition of separate taxa.

Two experiments (laboratory and field-laboratory) were designed to determine whether individual bank voles Clethrionomys glareolus (Schreber, 1780) and yellow-necked mice Apodemus flavicollis (Melchior, 1834) could distinguish heterospecific odour cues from familiar and unfamiliar individuals. In the laboratory experiment each male bank vole was familiarized for 24 h with odour (cotton wool impregnated with urine and faeces) of male yellow-necked mice and yellow-necked mice were familiarized with odour of male bank voles. In the field-laboratory experiment the individual bank voles and yellow-necked mice captured at the same point were considered familiar and transfered to the laboratory. In laboratory, these individuals were tested in a box (for 5 h) affording them the choice between the odours of familiar and unfamiliar heterospecific males. Bank voles discriminated between familiar and unfamiliar yellow- -necked mouse odours. Male yellow-necked mice seemed to have a similar ability to recognise odours of familiar bank voles. It is proposed that interactions between these two species occur not only on the species level, but also on the level of individual. This phenomenon (probably asymmetric) can play an important role in spatial orientation, and influence direct contacts between individuals of these species.

Specific recognition between proteins plays a crucial role in a great number of vital processes. In this review different types of protein-protein complexes are analyzed on the basis of their three-dimensional structures which became available in recent years. The complexes which are analyzed include: those resulting from different types of recognition between proteinase and protein inhibitor (canonical inhibitors of serine proteinases, hirudin, inhibitors of cysteine proteinases, carboxypeptidase inhibitor), barnase-barstar, human growth hormone-receptor and antibody-antigen. It seems obvious that specific and strong protein-protein recognition is achieved in many different ways. To further explore this question, the structural information was analyzed together with kinetic and thermodynamic data available for the respective complexes. It appears that the energy and rates of specific recognition of proteins are influenced by many different factors, including: area of interacting surfaces; complementarity of shapes, charges and hydrogen bonds; water structure at the interface; conformational changes; additivity and cooperativity of individual interactions, steric effects and various (conformational, hydration) entropy changes.
