Brain patterns are compared by quantitative histology in 28 native and introduced mid-European cyprinid species, considering 17 primary sensory and higher order brain areas. Cluster analysis (CLA) and principal component analysis (PCA) based on relative volumes of these brain areas indicate that cyprinid brains are diversified into four major groups, basic(More)
To provide a hitherto lacking review which focuses on gill surface area of freshwater fish, we collected and analysed morphometric data from the literature. The scaling exponent of gill area ranges from 0.36 to 1.13, with a mean value of 0.76. The absolute values for the largest gill areas are about 5 times as high as those of the smallest. This range(More)
The aim of the present qualitative and quantitative study was to survey the density and distribution of external taste buds (TB) in 10 common European cyprinid species. TB pores were stained with silver nitrate and counted in 7 sample areas on the body and 3 on the fins. TB densities decrease from rostral to caudal and from ventral to dorsal. Highest(More)
The abundance of active soil ciliates was determined by Singh's dilution culture method any by the direct counting method of Lüftenegger et al. (1988) in 13 samples of 3 types of soil (meadow topsoil, spruce and beech litter). This comparative investigation revealed that the dilution culture methods are likely to overestimate active ciliates by orders of(More)
