The aim of the work was to make a systemic study of the variability of the human musculus peroneus tertius during the foetal period. Examination was made of 193 foetuses of ages ranging from 84 to 256 days after conception. The results obtained indicated that the musculus peroneus tertius was present in 83.16% of the human foetuses studied and that its intrauterine development was progressive and almost proportional. Previous studies have not revealed dimorphic or bilateral differences with respect to any of the features examined. On the basis of the examinations and bibliographical data a uniform typology of the musculus peroneus tertius variants was created and three final types were distinguished: the pithecogenic (44% cases), eugenic (34% cases) and progenic (22% cases).

The differences in morpho-anatomical, ecological and biochemical traits of Cyclamen coum subsp. coum, threatened plant listed in CITES (Convention on International Trade in Endangered Species of Wild Fauna & Flora) have been investigated in the central Black Sea region of Turkey in the context of its distribution at different altitudes. We found that shoot length, bulb width, leaf width and length, number of branches and flowers were significantly different along elevation gradient, whereas length of tubers, number of living and dead leaves, number of nodes, specific leaf area (SLA) and leaf mass area (LMA) values, did not differ significantly, PCA analysis revealed that leaf length and width, the number of branches, soil organic matter content and available potassium concentration and N concentrations of above and belowground parts and reproductive effort (RE3) played significant role in differentiation of the studied populations, while several other studied factor were found not significant. The reproductive effort of individuals from the sea level was higher. We suggest that significant differences in the studied traits may indicate the ecotypic differentiation among populations.

Successive degradation of tissues in a strict order was observed in unfertilized ovules of the endemitic species Daphne arbuscula (Čelak) before flower drop. Cell death begins in the nucellus and inner integument in the vicinity of the vascular bundle terminal, proceeds in the outer integument and ends in the ovary wall. This successivity corresponds with that of programmed recycling described for senescing leaves of deciduous trees. In the extreme conditions of the D. arbuscula habitus, flowering is abundant but fertilization of ovules is relatively rare and seed set is low, so recycling of nutrients from tissues of unfertilized ovules should be expected as part of the life strategy of this species.
