abstract = {The association between patch metrics and roosting site (n = 31) suitability of Lyle’s flying fox (Pteropus
lylei) in 26 Central Eastern and Western provinces of Thailand was quantified. Land use classes with 90-m
resolution were identified based on various vegetation and land cover types to calculate patch metrics using
FRAGSTATS. Then, Maximum Entropy Modeling (MaxEnt) was performed using patch metrics covariates
to produce a predictive potential distribution map. The results indicated that patch contiguity (contiguity
index, 63.7%), patch area (29.3%), and patch shape complexity (shape index, 5.7%) are the most influential
patch metrics, all of which have negative effects on roosting site suitability. In total, 13,222 small patches
were considered highly suitable patches, with a mean area of 0.921 ± 0.698 (SD) ha, which accounted for
122,090 ha (2.04%) of the study area. Roosting sites predicted from the model were consistently associated
with occurrences of roosting sites observed in temples; such habitats likely provide shelter from external
threats for colonies roosting in a human-dominated landscape.},

In Slovakia, European yew (Taxus baccata L.) is a threatened species protected by law and present in many protected areas. In the study, we emphasize that protecting land and individual plants may not be sufficient for maintaining of yew populations, unless controlling over damage by deer game is also undertaken. Our results show that in beech forests of the Veľká Fatra Mts, browsing and bark peeling constitute the main negative factor affecting yew seedling-sapling ingrowth transition, and the mortality and vitality loss of adult yew trees. We argue that ungulates may have a larger effect on biodiversity conservation than currently realized.},

abstract = {This paper examines the role of ecological factors, derived from principal component analysis performed on edaphic and vegetational dataset as well as spatial variables, in structuring the soil macrofauna community of the Dnipro floodplain within the ‘Dnipro-Orilsky’ Nature Reserve (Ukraine). The soil macrofauna was defined as invertebrates visible to the naked eye (macroscopic organisms). The test points formed a regular grid with a mesh size of 3 m with 7 × 15 dimensions. Thus, the total test point number was 105. At each point, soil-zoological samples of 0.25 × 0.25 m were taken for quantifying the soil macrofauna. The spatial structure was modeled by a set of independent spatial patterns obtained by means of principal coordinates of neighbor matrices analysis (PCNM-variables). Spatial PCNM-variables explain significantly more variations of the community (19.9%) than edaphic factors (4.1%) and vegetation factors (3.2%). Spatial and combined environmental and spatial effects were divided into three components: broad-scale component was characterized by periodicity of spatial variation with a wavelength of 24.0–44.5 m, medium-scale – 11.1–20 m, fine-scale 6.6–11.0 m. For a broad-scale component, environmental factors of a vegetational nature are more important, for medium-scale, edaphic factors are more important, for fine-scale, both vegetation and edaphic are important. For litter-dwelling animals, the most characteristic spatial patterns are on the broad and medium-scale levels. For endogeic and anecic animals, the most significant variability is on the fine-scale level.},

permanent research areas by using the CMR method. Besides the changes of selected habitat variables, we
were also continually measuring values of meteorological elements (such as air and soil temperature, relative
air and soil humidity, thickness and duration of snow cover). Statistical testing of the thickness and duration
of snow cover proved significant influence of these factors on the population dynamics of small rodents
(Rodentia) and shrews (Soricomorpha). Winters with a thicker snow cover and longer snow periods had
a positive effect on the reproduction and surviving of both taxonomic groups in the subsequent vegetation
season. We have discovered the positive correlation between the temperature and the quantity dynamics of
dominant small rodents while shrews responded to higher temperatures with less spatio-temporal activity.
Gradient analysis of the complex influence of measured meteorological elements proved species-specific
differences in the responses of small mammals to the current and conditions of weather indicated by ecological
requirements of plant species within a specific habitat.},

CHMI, in original language Český hydrometeorologický ústav. The data assembled over this period were used for identification of timing of the following vegetative phenophases: bud burst (BBCH 07), first leaves 100% (BBCH 15), leaf colouring 10% (BBCH 92), leaf fall 100% (BBCH 97). The stations are situated at altidudes from 165 m (Lednice) to 1,102 m (Modrava). The mean date obtained for onset of bud burst is from April 12th to May 7 th (on average April 22nd), the mean date for onset of the first leaves 100% is from April 29th to May 17th (on average May 7th), the mean date for onset of leaf colouring is from September 12th to October 14th (on average September 24th ), and the mean date for onset of leaf fall 100% is from October 9th to December 8th (on average November 7th). The trend analysis of bud burst stage showed a declining trend - that means a shift of phenological phases towards earlier date (5.7 days). On the other side, the phenophase of leaf fall 100% manifested an increasing trend - that means a shift of phenological phase to later date (6.1 days). The vegetation season is getting longer. The totals of effective temperatures were used as a bio-climatological criterion for assessment of dependence of phenological phases on meteorological variables. The above mentioned totals were obtained as subtotals of average daily temperatures higher than 0 °C, 5 °C, 8 °C and 10 °C (TS0, TS5, TS8, TS10). The average temperature total for bud burst TS0 was found from 286.2 °C (Lednice, 165 m a.s.l.) to TS0 = 144.2 °C (Modrava, 1,102 m a.s.l.). The other effective temperature totals for the average day of bud burst are: TS5 = 71.5 °C; TS8 = 21.4 °C; TS10 = 7.2 °C (Lednice); TS5 = 20.0 °C; TS8 = 4.4 °C; TS10 = 1.6 °C (Modrava). The highest temperature total for leaf fall was from TS0 = 3,822.4 °C (Lednice); the lowest TS0 = 1845.9 °C (Modrava).},

Soil management practices such as the application of mulches or the formation of a soil micro relief through tillage modify the thermal regime of soils. The aim of this study was to compare the effects of soil tillage and the application of stubble mulch and different amounts of straw mulch on the thermal behaviour of a Luvisol. The experiments were performed from January to May 2007, in a field sown with winter wheat. Temperature was measured with copper-constantan thermocouples placed over straw and over stubble, at soil surface and at 2, 4 and 8 cm depths. Compared with tilled bare soil, the application of straw mulch seems to affect the soil thermal regime more significantly than that of stubble mulch. The topsoil under straw mulch showed the lowest thermal amplitudes and the highest minimum temperatures. From March to May, the mean temperatures in the profiles covered by straw were significantly lower than those recorded on the remaining plots. Implications of these techniques for soil temperature control in crop growing are discussed too.},

abstract = {Sweet chestnut (Castanea sativa Mill.) is marginally distributed - as a rare species, in Hyrcanian forest, located in the north of Iran. In Iran, this species is economically important for timber and nut production, therefore its conservation is very necessary. However, no information exists on its variability in the Iranian chestnut populations. The aim of this study is to survey the variability in leaf morphology of three chestnut natural populations. Twenty trees per a population and forty leaves per a tree were sampled, data of nine characteristics (lamina length, lamina width, petiole length, distance from leaf base to the leaf maximum width, tooth width, tooth length, tooth distance, vein (count variable), teeth (counted variable) and four characteristic ratios (leaf length/leaf width, leaf length/petiole length, leaf length/distance from leaf base to the widest point, distance from leaf base to the leaf widest point/petiole length), were recorded. Principal components analysis (PCA) was used to separate inter-relationships into statistically independent basic components. Most of the variation (85%) was explained by the first four components, and leaf size emerged as the most important variable in the corresponding eigenvectors. We used one-way ANOVA on the scores of the factors extracted in the PCA. These analyses revealed significant between-population differences with regard to most of factors. The results of discriminant analysis showed a high percentage of correctly classified cases in all actual populations (in total 93%). The patterns of leaf plasticity exhibited low values for all parameters. We concluded that leaf parameters are suitable variables for detecting levels of phenotypic variability among chestnut natural populations. The high diversity observed in the populations is very important for the conservation of the species genetic resources.},

The results of the monitoring show different starts and durations of phenological phases in individual years. A large range was noted in spring phenological phases. The start and duration of autumnal phenological phases has more regular character. The annual variability in the start and course of phenological phases in beech shows that in addition to genetic factors, also external conditions, particularly meteorological factors, participate in their start and duration. Relationships between the start of phenological phases and changing meteorological parameters are expressed with the sum of effective air temperatures higher than 5°C. Also growth phases were evaluated in relation to vegetative phenological phases. On the basis of the results obtained it is evident that in recent years, the growth of the sum of effective air temperatures occurs, particularly in the autumnal season with extension of the growing season, which can result in the disturbance of physiological functions causing, in such a way, forest decline. Results of phenological monitoring can contribute to explain effects of climatic changes on the stability of forest stands.},

The parameters were recorded at every 5 cm to a depth of 50 cm. The environmental parameters were determined by phytoindication. Geostatistical analysis showed the average level of spatial dependence of soil penetration resistance. According to the features of the profile variation in penetration resistance with the depth, the measurement points have been divided into three clusters.

Therefore, the objective of this study was to identify which physical soil properties enhance or limit the vitality of the studied introduced trees in the Arboretum Mlyňany. Soil properties were studied in seven soil profiles under dense monocultures of Chamaecyparis lawsoniana, Liriodendron tulipifera, Juniperus Chinensis, Thuja orientalis, Thuja plicata, Picea orientalis and Pinus nigra. The results showed that all stagnic horizons had exceeded the limit values of total porosity and bulk density, hence these horizons were compacted. Based on the soil and climatic requirements of the examined trees we conclude that the soil properties of their sites in arboretum are suitable for: Chamaecyparis lawsoniana, Liriodendron tulipifera, Thuja orientalis and Pinus nigra. Nevertheless, physical properties in profiles under Picea orientalis and Juniperus Chinensis do not permit rapid drainage of water, what is unfavourable for healthy development of these two species; while Thuja plicata demanding high moisture supply is grown on soil with high coarse porosity, a prerequisite of fast rainwater drainage. However, since none of the studied introduced trees had suffered from physiological disorders or diseases, they may be declared acclimatized well in the soil-climate conditions described in this study. © 2017 Authors.},

The contents of arsenic and nutrients (Cat, Mgt, Kt, Nat), with exception of calcium in the beech litterfall from the stressed stand were markedly higher (by 4.3%, 23.9%, 2.1% and 87.9%, respectively) compared to the samples taken from the control plot. On the contrary, the surface humus samples (with the exception of Na in the necrotic Oon subhorizon) from control plot were richer in nutrients. However, significant differences (p < 0.01) between the plots were observed for Ca content in the litterfall as well as in the surface humus. The concentrations of As in Oo samples from the stressed stand mainly increased with the organic horizon depth (mg kg-1): necrotic Oon 1.10 < fermentation Oof 3.1 < humification Ooh 55.6. The results showed, that As amounts detected in subhorizon Ooh and in beech litterfall from the stressed stand were higher than the limit values, thus indicating that the environment of the Žiar territory is exposed to persistent negative impacts of industrial activities. © 2017 Authors.},
