Thermal and snowy conditions in Zagożdżonka River catchment during hydrological years 2003–2013 and winter floods are presented in paper. The meteorological and hydrological data, such as maximum, minimum, mean diurnal air temperatures, daily snow cover depth, and water discharge, collected at Czarna station (WULS-SGGW) have been used. Meteorological conditions were analyzed using indexes proposed by Paczos. Temperate cold and extraordinarily low snowy winters has dominated in Zagożdżonka catchment in presented period of time. Winter floods as a result of snowmelt have been observed almost each year, except 2008 when winter was mild and extremely low snowy. The relation between winter severity index (WOz) and winter snowiness index (WSn) has been estimated, as well as the relation between winter snowiness index and maximum discharge (Qmax).

The main objective of this article was to determine thermal conditions in the Christmas period and the impact of atmospheric circulation on their formation. The article is based on data on the mean daily air temperature for 16 stations in Poland for the 1966–2014 multiannual period. In this period, no statistically significant changes of air temperature were observed, neither in December, nor the Christmas period. The occurrence of averagely warmer holidays was associated with the inflow of maritime polar air masses from the western sector, while colder holidays occurred with the inflow of continental polar air masses from the eastern sector.

Doświadczenia polowe przeprowadzono w latach 2005 i 2006 w dwóch miejscowościach: Lipniku, koło Stargardu Szczecińskiego (gleba klasy bonitacyjnej IVb, kompleks przydatności rolniczej żytni dobry), i Kruszynie Krajeńskim, koło Bydgoszczy (gleba klasy bonitacyjnej V, kompleks przydatności rolniczej żytni słaby. Doświadczenia założono w układzie zależnym „split-plot” w 3 powtórzeniach. Badano dwa czynniki: nawadnianie (kontrola, deszczowanie) i nawożenie azotem (0, 40, 80 i 120 kg N·ha–1). Plony prosa uprawianego na glebie klasy V bez nawadniania zależały od ilości opadów w okresie wegetacji. Mniejsze plony (1.46 t·ha–1) zanotowano w roku o niższych opadach (161 mm od 1 maja do 31 sierpnia). Większe plony (2,45 t·ha–1) otrzymano w roku z wyższymi opadami (229 mm). Potrzeby wodne prosa w okresie wegetacji (maj – sierpień), oszacowane jako tzw. opady optymalne według Klatta i Pressa, były większe na glebie bardzo lekkiej (V klasa) w Kruszynie Krajeńskim (wynosząc odpowiednio 278 i 294 mm) niż policzone dla gleby lekkiej (klasa IVb) w Lipniku (odpowiedno 260 i 256 mm). Najwyższe niedobory opadów w okresie wegetacji prosa, policzone jako różnica pomiędzy opadami optymalnymi według Klatta i Pressa dla określonego miesiąca a sumą opadów rzeczywistych, zanotowano w lipcu. Efekty produkcyjne nawadniania zależały od kompleksu glebowego. Deszczowanie istotnie zwiększyło plony ziarna prosa odmiany ‘Jagna’ o 1,9 t·ha–1 (97%) na glebie bardzo lekkiej (Kruszyn Krajeński). W warunkach gleby lekkiej (Lipnik) deszczowanie zwiększyło plony ziarna o 0,6 t·ha–1 (17%). Wzrastające dawki nawożenia azotowego (od 0 do 120 kg N·ha–1) spowodowały (w warunkach deszczowania) istotny przyrost plonu ziarna prosa do poziomu 4,53 t·ha–1 na glebie V klasy i 4,07 t·ha–1na glebie klasy IVb.

In 2007 and 2008 studies aimed to determine the effect of preparation belonging to carbamate compounds (Pirimor 500 WG), organophosphorus compounds (Diazol 500 EW), and quinazolin compounds (Magus 200 SC), on the oxygen consumption rate by adult beetles Anoplotrupes stercorosus were performed. Experiments were carried out under diverse ambient temperatures (14, 19, 24 i 29°C) using two ways of intoxication – contact intoxication or intoxication by ingestion of the biocide. In control insects the ambient temperature affected the oxygen demand only to a small extent. Usually, insecticide preparations which were used, markedly potentiated the oxygen consumption. In those experimental groups significant increases of oxygen consumption as the effect of ambient temperature elevation were noted. The mode of the intoxication influenced oxygen consumption only very slightly. The highest values of oxygen consumption were noted in animals treated by contact intoxication.

The paper summarises the results of climatological studies concerning the area of the Carpathian Regional Gene Bank station located in the Wisła Forest District. The work provides raw meteorological data, daily, monthly, seasonal and annual records, and various indices such as the pluvial-thermal index, biometeorological index, Sielianinow’s index and de Martonne’s index. In addition, the detailed profiles of thermal, humidity and rainfall conditions are presented against a background of the general synoptic situation.

The aim of the study was to determine the oxygen consumption (OC, mg O₂ kg⁻¹h⁻¹) and ammonia production (AE, mg TAN kg⁻¹h⁻¹) of perch reared in a recirculating system at the optimal temperature for this species of 23°C. The studies were conducted when the fish were undergoing intense fattening on artificial feed. Measurements of metabolic rate were taken 24 hours per day in six size groups of fish (mean body weights (BW) in each group - 18.4, 30.7, 46.4, 56.5, 67.8, 82.3 g). Within the studied perch size range, OC decreased from 336.2 to 185.0 mg O₂ kg⁻¹h⁻¹, and AE from 22.0 to 5.6 mg TAN kg⁻¹h⁻¹. An increase in body weight by 1 g led to an average decrease in oxygen consumption by a mean of 2.53 mg O₂ kg⁻¹h⁻¹ and ammonia excretion by 0.28 mg TAN kg⁻¹ h⁻¹. During the analyzed period, the body weight of perch, the arithmetic dependence between OC-BW and AE-BW, was linear and the determination coefficients R² of the linear regression equations describing these relationships were highly statistically significant at a value exceeding 0.9.
