Changing localized environmental conditions along altitude gradients could modify the responses of tree xylem structures to climate variations. To explore how trees adapt to local environment and respond to climate variants, we analysed the variation of Picea meyeri xylem tracheid features and the relationships with climate variables along an altitude gradient (1970, 2240, 2490 and 2650 m above sea level) of the Luyashan Mountains in the North China. The results mainly indicated the following: (1) tracheid number and diameter of P. meyeri showed significant differences among the four sites along the altitude gradient; (2) trees at site 2 (2240 m) and site 3 (2490 m) are similar in age, but the xylem tracheid number and diameter of these trees were significantly different, which may indicate different functional adaptation; (3) the relationships between xylem features' residual chronologies and the monthly climate data were inconsistent along altitude gradients, which indicated that the limiting factor of P. meyeri growth along the altitude gradients, shifted from drought stress at lower altitudes to low-temperature stress at higher altitudes.

So far in Poland, the Asian clam Corbicula fluminea has been reported from the Oder (Odra) and Vistula River. Its new population has been discovered in the Warta-Gopło Canal in Konin (central Poland), where water temperature can reach 34°C, as the canal is a part of a power plant lake cooling system. The spatial distribution of C. fluminea was found to be very uneven and that is probably why this species was not found during earlier research. The highest density of C. fluminea was 78 ind.·m⁻² at the site where water flow was the fastest (2.49 m·s⁻¹), providing sufficient oxygenation of the water. The results suggest that existing information about the distribution of C. fluminea may be far from complete because the clam can be present also in the habitats that were not regarded as suitable for the species according to earlier reports, and therefore have not been monitored for its presence.

Chemical composition of 12 weed species occurring in cereals and roots crops cultivated in south-eastern Poland was investigated. Weed samples from 7 types of habitats differing in their physiographic and pedagogic conditions were collected. Contents of P, K, Ca, Zn, Pb and Cd in weed tops were analyzed. It was found that the levels of macronutiens and heavy metals in weeds, especially Ca, Zn and Cd depended on the region of sampling and species of weed.

Our aim was to determine dynamics in a population of tawny owls Strix aluco over 15-year period, in relation to year-to-year variation in environmental conditions. The research was carried out in a habitat mosaic of fields and forest in central Poland, over the 2004–2018 period. Numbers of pairs (territories) were established by the standard playback survey technique supplemented by searches for nest sites. The selected environmental factors studied in parallel were the acorn production, density changes in field and forest rodents, meteorological conditions in winter and density of martens (Martes spp.). At the start of the study period 20 nest boxes designed for tawny owls were placed out in the study area. This number was enlarged by additional 27 nest boxes placed in 2012. The number of owls in the area remained stable – in the range of 26–29 pairs, despite changes in nesting sites availability. However, moderate influence of rodent density and winter conditions on population abundance was detected. Also, peak in the rodent population coincided with greater clutch size and numbers of young owls reared. Densities of martens remained relatively stable throughout the study period, and there were no reported cases of these carnivores killing tawny owls, despite the former taking shelter in the owl-boxes.

W pracy wykorzystano dane z lat 2010-2013 dotyczące zawartości skrobi w bulwach średnio wczesnych odmian ziemniaka jadalnego. Dane pochodziły z sześciu stacji COBORU położonych w różnych rejonach Polski. Wykonano analizę wariancji zgodnie z modelem trzyczynnikowej klasyfikacji krzyżowej z jedną obserwacją w podklasie. Wykazano istotny wpływ miejscowości, lat badań oraz odmian na zawartość skrobi. Istotna okazała się również interakcja lat i miejscowości oraz interakcja miejscowości i odmian. Niezależnie od odmiany najwyższą zawarto-ścią skrobi charakteryzowały się bulwy ziemniaka zbierane w Uhninie, a najniższą w Słupi. Najwię-cej skrobi zgromadziły bulwy w 2013 roku, istotnie mniej w 2012, a najmniej w roku 2010. Lata 2012-2013 w większości stacji charakteryzowały się niższymi sumami opadów okresu wegetacyj-nego w porównaniu do lat 2010-2011. Najwięcej skrobi zgromadziły odmiany Gawin oraz Tajfun. Odmiana Finezja charakteryzowała się taką samą skrobiowością jak odmiana Cekin. Porównywalne pod względem zawartości skrobi były również odmiany Stasia i Ametyst, a najmniejszą zawarto-ścią skrobi charakteryzowała się odmiana Satina.

Effect of variable temperature and moisture content conditions on selected properties of wood-CFRP composite Intended structural application of wood-CFRP composite requires analysis of its properties in time function, including environmental conditions changes. The paper presents results of selected mechanical and physical properties of composite, using artificial aging methods. It was shown that artificial aging cycles determined according to standards and other regulations, relating to 1 year of natural aging, caused a decrease of composite's density, as well as a significant decrease of Young's modulus, with negligible change in the values of bending strength.

Over the past 50 years, the complete histological study of carp fish gonads was first carried out at Zaporozhian Reservoir. In conditions of environmental transformation of the reservoir the regularities of oogenesis and gonadogenesis, passing sexual cycles were found and the ecology of spawning carp fish was investigated. The adaptive potential of the carp fish reproductive systems, which is expressed through the asynchrony of reproductive products development as well as the functional peculiarities of the fish spawning process, was brought to light. Both environmental assessment and faunal analysis of biodiversity and distribution of young fish of Zaporozhian Reservoir were carried out. The growth and development of the fish larvae dwelling within the industrial agglomerations of Dnipropetrovsk city are found to be under anthropogenic influence. The efficiency of the use of artificial spawning nests for the carp fish spawning was studied, and practical recommendations for their installation and operation in the waters of the reservoir were elaborated.

Omówiono uwarunkowania społeczne, ekonomiczne i środowiskowe uzasadniające rozwój ekoturystyki jako alternatywnej formy wykorzystania niektórych gruntów rolnych w makroregionie północno-wschodnim. Oceniono również spodziewane indywidualne korzyści ekonomiczne związane ze zmianą funkcji rolniczej na turystyczno-wypoczynkową. Jako miernik do oceny korzyści wykorzystano kategorię renty turystycznej i renty planistycznej.
