The digestibility coefficient and metabolizable energy (ME) content of the most important pigeon feeds (corn, wheat, barley, red and white millet, sorghum, canary seed, peas, lentils, sunflower, and hemp) were determined. The experiment was carried out using 10 adult male homing pigeons. All feeds were fed alone, in a whole-grain form, ad libitum. Drinking(More)
In the last decade, several studies have shown that subterranean aquatic habitats harbor cryptic species with restricted geographic ranges, frequently occurring as isolated populations. Previous studies on aquatic subterranean species have implied that habitat heterogeneity can promote speciation and that speciation events can be predicted from species'(More)
The effect of breed and sex on adult body composition of four pigeon breeds: Texan (TEX), Mondain (MON), Szeged Tumbler (SZT), and homing (HOM) and on the digestibility coefficients (DC) and metabolizable energy (ME) content of their feeds was studied. A total of eight groups, each comprising five males and five females of each breed, were used. All birds(More)
The purpose of this study was to examine the sensitivity, in a field situation, of the hyporheic fauna to pollution by heavy metals and also to test the use of oxidative stress enzymes produced by this fauna as a sensitive indicator of oxidative stress generated by chemical contamination. This was done by surveying the patterns of distribution, structure,(More)
Ancient DNA studies have revolutionized the study of extinct species and populations, providing insights on phylogeny, phylogeography, admixture and demographic history. However, inferences on behaviour and sociality have been far less frequent. Here, we investigate the complete mitochondrial genomes of extinct Late Pleistocene cave bears and middle(More)
The sampling effect may reflect artifactual trends in species richness and distribution across various spatiotemporal scales. The paper aims to examine how sampling frequency impacts the observed community dynamics in groundwater habitats of the unsaturated zone of the Ciur Izbuc cave (northwestern Romania) and addresses data interpretation biases that can(More)
Amiracarus pliocennatus n. gen., n. sp. is described based on fossils found in Pliocene and Pleistocene clastic sediments in caves of the Slovenian Classical Karst (Kras). Diagnosis and relationships of the new genus are given and relationships within the extant species of the genus are discussed as well as variability and reliability of some characters,(More)
