Amur sleeper (Perccottus glenii Dubowski, 1877) spreading in the Danube river basin
(Wiley, Hoboken, 2007)
Whereas earlier Amur sleeper (Perccottus glenii) findings in the Danube River were only single specimens, data reported in this study represent the first record on establishment of a local population. An overview of the ...
Using optical fibers to measure absorption in intact conifer leaves, relative numbers of chloroplasts, and pigment content
(Springer, Dordrecht, 2020)
For investigations of ongoing processes in plants, such as photosynthesis in conifer leaves, nondestructive and noninvasive measuring techniques are needed. In this paper, a novel approach has been developed for the ...
Optimization of process of the honeycomb-like structure formation by the regime of reversing current (RC) in the second range
(Springer, New York, 2020)
Formation of the honeycomb-like electrodes of copper by the regime of reversing current (RC) in the second range has been investigated. Morphological and structural characteristics of this electrode type obtained by various ...
Comparison of Photoacoustic Signals in Photosynthetic and Nonphotosynthetic Leaf Tissues of Variegated Pelargonium zonale
(Springer/Plenum Publishers, New York, 2016)
Green-white variegated leaves of Pelargonium zonale were studied using the photoacoustic method. Our aim was to characterize photosynthetically active green tissue and nonphotosynthetically active white tissue by the ...
Sensitivity of Bleak (Alburnus alburnus) in Detection of the Wastewater Related Pressure in Large Lowland Rivers
(Springer, New York, 2020)
This study deals with bleak (Alburnus alburnus) sensitivity in detecting of the wastewater related pressure in large lowland rivers. The major objective was to investigate if the response measured in bleak should be linked ...
First record of smoltified rainbow trout Oncorhynchus mykiss (Walbaum, 1792) in the main riverbed of the Serbian part of the Danube River
(Wiley-Blackwell, Hoboken, 2016)
Several fish species in the family Salmonidae have evolved multiple life
history forms that exploit different degrees of anadromy (McMillan,
Pess, & Katz, 2007) and one of these is rainbow trout (Oncorhynchus
mykiss). ...
Paddlefish (Polyodon spathula) in Europe: An aquaculture species and a potential invader
(Wiley, Hoboken, 2019)
The paddlefish (Polyodon spathula) was first introduced to Europe in 1974, mainly due to its potential for rearing in natural polyculture ponds and large temperate reservoirs. The information on the history of paddlefish ...
Variability of morpho-anatomical characteristics of bald cypress needles from topcider park (Belgrade)
(Parlar Scientific Publications (P S P), Freising, 2018)
There have been analyzed morho-anatomical characteristics of bald cypress needles from Topcider Park (Belgrade). In order to perform the research, it was chosen 5 test stems and from all of them, 20 needles from branches ...
Air pollutant effects on chlorenchyma cell and chloroplasts of Douglas-fir (pseudotsuga menziesii (Mirb.) Franco) needles
(Parlar Scientific Publications (P S P), Freising, 2017)
This paper presents the results of air-pollutant influence on one-year and two-year old needles of Douglas-fir. The aim of this research was determining of resistance of these species. The analysis was performed on samples ...
Isopiestic Determination of the Osmotic and Activity Coefficients of the {yNaH(2)PO(4)+(1-y)KH2PO4}(aq) System at T=298.15K
(Springer/Plenum Publishers, New York, 2019)
Isopiestic measurements have been made for aqueous mixtures of NaH2PO4 and KH2PO4 at T=(298.15 +/- 0.01) K, at NaH2PO4 ionic strength fractions y=(0, 0.19108, 0.38306, 0.58192, and 1), assuming that both electrolytes ...
