Aims: To define territorial borders that exist within a nuthatch population and to compare densities of trees and cavities between used and non-used parts of their available habitat in order to determine habitat preferences. Methods: The number and location of territories was estimated by mapping the individual positions of colour-ringed birds. We measured habitat characteristics in regular sampling grid (number of trees and number of cavities per 50×50 m) during three successive seasons and modelled probability of occurrence of nuthatch territories in the area. Results: Breeding pairs were observed to defend territories of median size between 1.46 and 2.93 ha. These sizes correspond well to high-quality habitat territories for this species. We found that pairs tended to occupy territories with higher densities of trees and cavities. Based on generalized linear mixed-effects model estimates, we found that in pastured oak woodland habitat with density of 60 trees per ha, the estimated probability of occurrence (with 95% confidence interval) of a nuthatch territory was about 96% (83−99). For cavity density, the probability of territory occurrence was about 74% (52−89) at the level of 60 cavities per ha. Conclusion: We suggest that higher tree and cavity densities reduce territory defence costs in the species because birds may use less energy during foraging, predation avoidance and competition for a nest hole.}, keywords = {}, pubstate = {published}, tppubtype = {article} } Capsule: In pastured old oak woodland, breeding pairs of Eurasian Nuthatch selected territories with significantly higher densities of trees and cavities.

This is in accordance with interspecific associations between ejaculate size and polyandry. However, lower slope of the intraspecific relationship may suggest lower importance of the ejaculate size in explaining females’ mating rate variability in this nuptial gift-giving species. |

In the spring trial interactions between tested trees and fungal isolates were not so frequent like in summer trials where more trees exhibited different response to the same virulent strain. Majority of trees showed different susceptibility in particular trials. Observed high variation of reactions of tested trees to both virulent and hypovirulent isolates has pointed at the need to prove other screening methods, and to find such one, that would be highly effective to reveal an inherited resistance and/or a lower degree of susceptibility to chestnut blight. |

We found a large variability in percentage of leaves longer than 70 mm (16–58%) and those of dark-green colour (28–78%), portion of half-full flowers (0–6%) and those of intense pink colour (0–100%), and percentage of hips longer than 20 mm (0–45%) and those of intense red colour (18–48%), among shrubs.

Caninae) from Malé Karpaty mountains (localities Modra – Pažite and Vrbové – Baraní dvor) and Zobor hills (locality Zobor – Lyžiarska lúka) were analysed. We found a large variability in percentage of leaves longer than 70 mm (16–58%) and those of dark-green colour (28–78%), portion of half-full flowers (0–6%) and those of intense pink colour (0–100%), and percentage of hips longer than 20 mm (0–45%) and those of intense red colour (18–48%), among shrubs. Their genome size ranged from 2.33 to 2.92 pg. Our map survey revealed stagni- eutric cambisols in Modra – Pažite, haplic luvisols on loess in Vrbové – Baraní dvor, and rendzic/ chromi-rendzic leptosols in Zobor – Lyžiarska lúka (increasing soil quality from stand to stand). Leaves and flowers grew in conditions of average temperature 15.3 °C (Modra – Pažite and Zobor – Lyžiarska lúka) and 14.5 °C (Vrbové – Baraní dvor).

Allometric relationships with slopes statistically smaller than 1.0 or higher than −1.0, were found between SM and LM and between mean leafing intensity and individual leaf mass, respectively, in long shoots.

Short shoots also had a larger fraction of biomass allocated to leaves. Beech shoots, as has been observed in other shoot dimorphic species, are specialized, with short shoots specializing in carbon gain and long shoots in space acquisition. A greater shift in LM than in SM among species during speciation shifting from allometric intraspecific relationships to an isometric interspecific scaling relationship between those traits could explain the discrepancies between the outputs of the present intraspecific study and others similar studies.

Non-overtopped individuals, not suppressed by surrounding saplings were sampled at the end of growing season. The total aboveground biomass production on the gradient varied within 1.7-261.0. Light in the log-log linear relationship accounted for 83% of this variability. The plants growing in the shade had lower mass of aboveground compartments, lower total leaf area, higher fraction of biomass allocated in foliar mass and lower in the in the woody mass compared to the plants growing in the high-light environment. The major changes in effects of light availability on biomass allocation occurred up to about 20% of Tot. Decreasing accessible light was responsible for a non-linear increase in interceptive leaf area per unit of biomass and decrease in amount of biomass allocated per a unit of branch and stem length – necessary for leaf display. There was a close correlation between mass of aboveground plant compartments, documented by Pearson’s r values of 0.98-0.99. Accompanied with different plant size, observed differences in biomass partitioning in response to light could be viewed as plastic adjustment to environmental heterogeneity in even-aged European beech saplings. |

However, in most cases the differences among the bud types are not distinct – individual types can be classified into several overlapping groups. The bud type significantly influences bud shape characterised by the ratios of BD to MD, and BD to L; on the other hand, it has no influence on MD/L and bud density (V/W). Influence of accessible light on bud shape and density also depends on bud type. For non-destructive estimation of V and W, we have prepared a regression model using as independent variable the volume of cylinder enclosing the bud (Vcyl). This model could explain 98% of the variation in V and W, with a relative accuracy of 6.4% for V, and 5.4% for W (P = 0.95). The performance of the model was verified by a test allowing us to conclude that the model outputs are comparable with directly measured values. |
