In concurrent with global warming, precipitation regimes are predicted to change as well around the world. In this study, two experimental sites were selected with different nutrient availability along a slope to study the effects of simulated increased precipitation on soil β-glucosidase activities in an Inner Mongolian grassland. Soil samples were adjusted to 55% of water holding capacity and incubated at 22°C in the dark for 32 days. Soil β-glucosidase activities were measured prior to and after the incubation. Results showed that soil β-glucosidase activities had differential responses to increased precipitation with a significant increase in the downslope site, but not in the upslope site. Correlation analysis showed that the initial soil β-glucosidase activities exerted a significantly negative relationship with soluble organic nitrogen (N). Our results indicated that both water availability and soil soluble N availability played important roles in regulating β-glucosidase activities in this semiarid region.

The study was to compare lipolytic activity and radial growth rate changes during the incubation of Thermomyces lanuginosus strains on natural (sunflower oil, soybean oil, rapeseed oil, and corn oil) and synthetic (tributyrin, Tween 20, Tween 40, Tween 60, Tween 80, and Tween 81) fatty substrata. The strains were isolated from different natural sources and incubated at 55°С on solid media containing natural and synthetic fatty substrata. The general (mean) lipolytic activity index decreased on natural substrata and increased on synthetic substrata during a five-day incubation period. The general daily growth rate changes were found to be similar on both natural and synthetic fatty substrata. However, the lipolytic activity index and daily growth rate changes were found to be highly differentiated on synthetic fatty substrata. Further studies on determination of the factors affecting the Thermomyces lanuginosus lipolytic activity are needed, due to the species is widely used for biotechnological purposes.

Because dilution plating is more labor intensive than direct plating, we would like to propose the use of a direct plating technique for estimation of Penicillium verrucosum abundance in cereal grain in incubation studies, with use of very selective and indicative for the fungus agar DYSG medium. The proposed method is based on the measurement of the diameter of P. verrucosum colonies grown around cereal kernels placed on DYSG medium. In three different experiments wheat grain contained a great range of P. verrucosum CFU number (from <25 to 77 x 10⁶ per 1 g). When P. verrucosum CFU number was at least as high as 10² per 1 g of the grain, 100% of the wheat kernels, placed on the surface of DYSG medium, were surrounded by colonies of P. verrucosum. The diameter (x, mm) of P. verrucosum colonies surrounding wheat kernels on DYSG medium was correlated with the fungal CFU number (y) on the wheat grain. The relationship is described by the exponential regression equation (y = 0.1258 e 0.9309x, R²=0.96). The relationship became linear (y = 0.404 x-0.901, R² = 0.96) after transformation of P. verrucosum CFU numbers to logarithms to base 10.

The influence of ß-haemolytic Streptococcus organisms at concentrations of 100 x, 200 x, and 500 x 10³ cells/ml sperm incubated at 37°C for 60 min with stallion semen suspension on the motility, viability and morphology of the semen, and AspAT activity in seminal plasma was examined. S. zooepidemicus at a concentration of 500 x 10³ cells/ml exhibited a particularly unfavourable effect on semen. All parameters measured altered significantly after a 60 min incubation. The activity of AspAT also changed during a prolonged incubation of sperm with a suspension containing 500 x 10³ S. zooepidemicus/ml semen; after a 24 h incubation the activity of AspAT was enhanced by more than 38% in comparison to the initial value.

Brood patches allow the transfer of heat to eggs for their successful embryonic development, and in many species determine egg temperature during incubation. We investigated brood patch development of Magellanic Penguins Spheniscus magellanicus in Isla Quiroga, Argentina, during 2012-2013. Here, we evaluate if brood patch development (in a narrow sense i.e. increase of the brood patch area and temperature measured with an electronic probe thermometer) varies according to laying date of the eggs, and with respect to adults' body condition and size, total clutch volume, and/or the sex of the adults. We found that brood patch temperature reaches its maximum when egg laying is finished, while brood patch area is fully developed starting from the end of the first quarter of the incubation period. The later the penguins started to breed the warmer the initial brood patches — when first egg is laid. Besides, the incubation period was shorter in penguins breeding late. Furthermore, adults in a good body condition had cooler initial brood patches than adults with poor body condition. In contrast, total clutch volume, body size index, and sex of the adults were not related to brood patch development. We conclude that initial brood patch temperature in Magellanic Penguins is associated with environmental factors, like laying date, and physiological attributes, like body condition.

W doświadczeniu inkubacyjnym badano zmiany zawartości mikroskładników w mieszaninach węgli brunatnych i osadów ściekowych. Komponenty zmieszano w proporcjach (węgiel brunatny : osad ściekowy) 1 : 5, 1 : 2, 1 : 1 i inkubowano przez 2 i 4 miesiące przy wilgotności 60% całkowitej pojemności wodnej i temperaturze 22-23°C. W badanych mieszaninach po mineralizacji „na sucho" oznaczono B, Mo, Mn, Co, Li i Ti metodą ICP-AES. Dodatek węgla brunatnego do osadu ściekowego wpłynął na zwiększenie zawartości boru i litu, a obniżenie poziomu molibdenu, manganu, kobaltu i tytanu. Wydłużenie czasu inkubacji do 4 miesięcy spowodowało nieistotne obniżenie poziomu boru, molibdenu, litu i tytanu w badanych mieszaninach. Rodzaj mieszanin istotnie różnicował zawartość boru, manganu, kobaltu, litu i tytanu.

W pracy wykorzystano gleby przez dwadzieścia lat nawożone mineralnie (NPK), w których fosfor stosowano w dawkach wynoszących 11 kg P·ha⁻¹ oraz gnojowicą (GN) w ilości 25 m³·ha⁻¹. Każdą z gleb inkubowano w stałej temperaturze przez 224 dni z dodatkiem fosforu mineralnego (w formie KH₂PO₄, w dawce 50 µg·g⁻¹ gleby) oraz bez fosforu (kontrola). Analizie poddano gleby w 0, 28 i 224 dniu inkubacji. W glebach nawożonych w przeszłości gnojowicą zanotowano trend do zwiększania się ilości fosforu w połączeniach z wapniem (P-Ca), kosztem frakcji P-Al. Frakcja fosforu rozpuszczalnego w glebie (P-lab.) stanowiła od 0,9 do 2,5% fosforu mineralnego. W okresie inkubacji największemu zróżnicowaniu podlegały frakcje fosforu P-Al oraz wodnorozpuszczalnego (P-lab.). W glebie nawożonej w przeszłości gnojowicą (GN), dodany fosfor mineralny stymulował mineralizację fosforu organicznego do 28 dnia inkubacji, lecz po zakończeniu eksperymentu nastąpiła immobilizacja fosforu mineralnego. W systemie nawożenia opartym o nawozy mineralne (NPK) dynamika przemian świeżo wprowadzonych fosforanów była mniejsza. Uwalniany w czasie inkubacji fosfor mineralny akumulował się w puli fosforu związanego z glinem (P-Al) oraz w formach wo- dnorozpuszczalnych (P-lab.), określanych mianem najlepiej przyswajalnych przez rośliny. Bieżące nawożenie fosforem wymaga uwzględnienia systemu nawo żenią
