population genetics after fragmentation: the case of the endangered spanish imperial eagle (aquila adalberti). | the highly endangered spanish imperial eagle, aquila adalberti, has suffered from both population decline and fragmentation during the last century. here we describe the current genetic status of the population using an extensive sampling of its current distribution range and both mitochondrial control region sequences and nuclear microsatellite markers. results were evaluated in comparison to those obtained for the eastern imperial eagle, aquila heliaca, its nearest extant relative. mitochondri ... | 2004 | 15245398 |
survey for hemoparasites in imperial eagles (aquila heliaca), steppe eagles (aquila nipalensis), and white-tailed sea eagles (haliaeetus albicilla) from kazakhstan. | prevalence of hemoparasites has been investigated in many avian species throughout europe and north america. basic hematologic surveys are the first step toward evaluating whether host-parasite prevalences observed in north america and europe occur elsewhere in the world. we collected blood smears from 94 nestling imperial eagles (aquila heliaca), five nestling steppe eagles (aquila nipalensis), and 14 nestling white-tailed sea eagles (haliaeetus albicilla) at naurzum zapovednik (naurzum nationa ... | 2004 | 15362834 |
using naturally shed feathers for individual identification, genetic parentage analyses, and population monitoring in an endangered eastern imperial eagle (aquila heliaca) population from kazakhstan. | genetic analyses on noninvasively collected samples have revolutionized how populations are monitored. most noninvasive monitoring studies have used hair or scat for individual identification of elusive mammals, but here we utilize naturally shed feathers. the eastern imperial eagle (eie) is a species of conservation concern throughout central asia and, like most raptors, eies are inherently challenging to study because adults are difficult to capture and band using conventional techniques. over ... | 2005 | 16101766 |
using modeling to improve monitoring of structured populations: are we collecting the right data? | population monitoring is central to most demographic studies and conservation efforts, but it may not always be directed at the most appropriate life stage. we used stochastic simulation modeling to evaluate the effectiveness of a monitoring program for a well-studied population of eastern imperial eagles (aquila heliaca) in kazakhstan. specifically, we asked whether the most appropriate data were being collected to understand system state and population dynamics. our models were parameterized w ... | 2007 | 17298530 |
[chewing-lice (phtihiraptera: amblycera, ischnocera) occurring on birds in the konya zoo]. | in this study, 25 birds belonging to 15 different species at the zoo in konya were inspected for the presence of chewing-lice. three long-legged buzzards (buteo rufinus), one imperial eagle (aquila heliaca) and one marsh harrier (circus aeruginosus) were found to be infested by chewing-lice. two hundred and eleven chewing-lice specimens were collected from the birds and seven species were identified. they were mounted on slides separately in faure forte medium or canada balsam after clearing in ... | 2009 | 19367546 |
integrative taxonomy of european parasitic flatworms of the genus metorchis looss, 1899 (trematoda: opisthorchiidae). | metorchis spp. are flukes (platyhelminthes: digenea) that infect vertebrates, including humans, dogs, cats, poultry and wild game, with cyprinid freshwater fish serving as typical second intermediate hosts. in their definitive hosts, the metorchis spp. are difficult to identify to species. we provide and analyze sequences of two nuclear (18s rdna and its2) and two mitochondrial (co1 and nd1) dna loci of four morphologically identified european species of the metorchis, namely metorchis albidus, ... | 2016 | 26794684 |
permanent genetic resources added to molecular ecology resources database 1 february 2012 - 31 march 2012. | this article documents the addition of 171 microsatellite marker loci and 27 pairs of single nucleotide polymorphism (snp) sequencing primers to the molecular ecology resources database. loci were developed for the following species: bombus pauloensis, cephalorhynchus heavisidii, cercospora sojina, harpyhaliaetus coronatus, hordeum vulgare, lachnolaimus maximus, oceanodroma monteiroi, puccinia striiformis f. sp. tritici, rhea americana, salmo salar, salmo trutta, schistocephalus solidus, sousa p ... | 2012 | 22642264 |
application of a single vascularised skin flap in eastern imperial eagle with skin defects. | skin defects are a frequent problem in avian clinical practice. they require rapid and effective therapy due to the absence of available skin around the skin defects and desiccation of the surrounding tissue. within the period of one year, between march 2010 and april 2011, several specimens of eastern imperial eagle (aquila heliaca) were treated at the clinic of exotic and free-living animals of the university of veterinary medicine and pharmacy in košice. three of them (cases 1, 2 and 3) had d ... | 2013 | 23396524 |
current efforts to monitor and conserve the eastern imperial eagle aquila heliaca in hungary. | the globally threatened eastern imperial eagle aquila heliaca has been one of the flagship species of hungarian bird conservation efforts since the 1980s. due to these conservation activities and positive land-use changes during the last 2 decades, the hungarian imperial eagle population increased from as few as approximately 20 pairs in the early 1980s to 81 pairs by 2006. between 2002 and 2005 as part of a life-nature project, mme/birdlife hungary carried out particularly intensive monitoring, ... | 2008 | 18833800 |
organochlorine and heavy metal contamination in the eggs of the spanish imperial eagle (aquila (heliaca) adalberti) and accompanying changes in eggshell morphology and chemistry. | eggs of the spanish imperial eagle (aquila (heliaca) adalberti) contained small amounts of heavy metals and organochlorine contaminants, including dde, aldrin, dieldrin and hchs, pcbs. levels of organochlorine, except dde, have decreased from 1972 to 1984. this paper reports how the structural and chemical characteristics of modern shells differ from those of older shells, unaffected by pesticides. also, fertile and infertile recent eggs are compared. a 12.6% decrease in eggshell thickness has o ... | 1988 | 15092620 |
hematocrit and blood chemistry values in captive raptors (gyps fulvus, buteo buteo, milvus migrans, aquila heliaca). | 1. eight hematological values were determined in blood samples from 88 raptors representing 10 species. 2. means, standard errors, ranges and coefficients of variations were obtained for each parameter and species investigated. 3. the griffon vulture (gyps fulvus) showed mean concentrations of glucose lower than those of most of the other species. 4. concentrations of urea in the buzzard (buteo buteo) were higher than those of the other raptors studied, and the black kite (milvus migrans) had ch ... | 1987 | 2887380 |

elevated heterozygosity in adults relative to juveniles provides evidence of viability selection on eagles and falcons. | viability selection yields adult populations that are more genetically variable than those of juveniles, producing a positive correlation between heterozygosity and survival. viability selection could be the result of decreased heterozygosity across many loci in inbred individuals and a subsequent decrease in survivorship resulting from the expression of the deleterious alleles. alternatively, locus-specific differences in genetic variability between adults and juveniles may be driven by forms o ... | 2019 | 31414124 |
