The aim of this study was to determine morphological patterns of the most abundant fish species found in reservoirs with different hydraulic retention times and stages of colonization, considering habitat strata and feeding strategies. Samplings were carried out in six Paraná State (Brazil) reservoirs, and morphological data were obtained from 15 individuals of 17 fish species. Ecomorphological attributes that best segregated species, were selected using Discriminant Analysis. These selected attributes were later used in a Principal Components Analysis (PCA). Differences among reservoirs concerning occupation of the ecomorphological space were tested through analysis of variance (null models). The six reservoirs differed in the occupation of the fish... |

ABSTRACT: Entomopathogenic nematodes ( Steinernematidaeand Heterorhabditidae) were studied in Polish soils according to the: season, habitat and altitude. In total, 167 soil samples were taken from 111 localities in Poland along north-south transect. Entomopathogenic nematodes were isolated from 53 soil samples (31.7%). Nematodes species were identified genetically from 16 samples, and in all other 37 samples nematodes were determined to the genus level. Three species of the genus Steinernema ( Steinernema kraussei, S. feltiae, S. carpocapsae) and one of the genus Heterorhabditis( Heterorhabditis megidis) were recorded. Steinernema feltiaewas the most common species. There was not a significant association between the occurrence of nematodes and season... |
