an experimental evaluation of the influence of water depth and bottom color on the common kingfisher's foraging performance.to investigate how depth and bottom color affect prey selectivity in common kingfisher (alcedo atthis), we developed several experimental procedures using captive birds. we used 20 young kingfishers to test depth (25 or 50cm) and color (natural gravel or white) effects on foraging behavior. live freshwater fish were used as target prey. to assess differences resulting from the natural behavior of different fish, we chose bottom-dwelling [ebro barbel (barbus graellsii)] and open-water benthopelag ...201323624098
using the kingfisher (alcedo atthis) as a bioindicator of pcbs and pbdes in the dinghushan biosphere reserve, china.the dinghushan biosphere reserve is a nature reserve and a site for the study of tropical and subtropical forest ecosystems. rapid industrialization and intensive electronic waste-recycling activities around the biosphere reserve have resulted in elevated levels of industrial organic contaminants in the local environment that may cause adverse effects on wildlife that inhabits this area. in the present study, polychlorinated biphenyls (pcbs), polybrominated diphenyl ethers (pbdes), and 2 alterna ...201323554012
enterococcus alcedinis sp. nov., isolated from common kingfisher (alcedo atthis).two gram-positive, catalase-negative bacterial strains were isolated from the cloaca of common kingfishers (alcedo atthis). repetitive sequence-based pcr fingerprinting using the (gtg)5 primer grouped these isolates into a single cluster separated from all known enterococcal species. the two strains revealed identical 16s rrna gene sequences placing them within the genus enterococcus with enterococcus aquimarinus lmg 16607(t) as the closest relative (97.14 % similarity). further taxonomic invest ...201323416573
characterization of three new mitochondrial genomes of coraciiformes (megaceryle lugubris, alcedo atthis, halcyon smyrnensis) and insights into their phylogenetics.coraciiformes contains more than 200 species with great differences on external morphology and life-style. the evolutionary relationships within coraciiformes and the phylogenetic placement of coraciiformes in aves are still questioned. mitochondrial genome (mitogenome) sequences are popular markers in molecular phylogenetic studies of birds. this study presented the genome characteristics of three new mitogenomes in coraciiformes and explored the phylogenetic relationships among coraciiformes a ...202033026411
molecular prey identification in central european piscivores.diet analysis is an important aspect when investigating the ecology of fish-eating animals and essential for assessing their functional role in food webs across aquatic and terrestrial ecosystems. the identification of fish remains in dietary samples, however, can be time-consuming and unsatisfying using conventional morphological analysis of prey remains. here, we present a two-step multiplex pcr system, comprised of six assays, allowing for rapid, sensitive and specific detection of fish dna i ...201626053612
hepatic ethoxyresorufin-o-deethylase induction in the common kingfisher from an electronic waste recycling site.the health effects of exposure to electronic waste (e-waste)-derived pollutants are an important issue. the authors explored the association between the hepatic levels of e-waste-derived halogenated contaminants (including polychlorinated biphenyls [pcbs], polybrominated diphenyl ethers [pbdes], and polybrominated biphenyls [pbbs]) and hepatic ethoxyresorufin-o-deethylase (erod) activity of the common kingfisher (alcedo atthis) from an e-waste site and 2 reference sites in south china. the summe ...201626509239
site-occupancy distribution modeling to correct population-trend estimates derived from opportunistic observations.species' assessments must frequently be derived from opportunistic observations made by volunteers (i.e., citizen scientists). interpretation of the resulting data to estimate population trends is plagued with problems, including teasing apart genuine population trends from variations in observation effort. we devised a way to correct for annual variation in effort when estimating trends in occupancy (species distribution) from faunal or floral databases of opportunistic observations. first, for ...201020337672
occurrence of microplastics in pellets from the common kingfisher (alcedo atthis) along the ticino river, north italy.previous research has reported avian plastic ingestion in marine bird species. yet, while research attention on plastic pollution is shifting from marine to freshwater ecosystems, very few information on plastic ingestion is available for freshwater birds. here, we examined the presence of microplastic in regurgitated pellets of the common kingfisher (alcedo atthis) collected along the ticino river (north italy). in total, 133 kingfisher's pellets were examined between march and october 2019 fro ...202032696405
