| aliphatic hydrocarbons in birds of prey from galicia (nw spain). | eleven aliphatic hydrocarbons, unresolved over resolved ratio (u/r), carbon preference index (cpi), pristane/c17 ratio, and totals were determined in six classes of tissues (heart, liver, intestine, muscle, lung, and kidney) of 10 buzzards (buteo buteo), 10 barn owls (tyto alba), and five tawny owls (strix aluco) from galicia (nw spain). among individuals detected at quantifiable levels, in general, c18 was found to be the most abundant. total aliphatic hydrocarbons were detected in 77% tissue s ... | 2001 | 11534951 |
| helminth fauna of falconiform and strigiform birds of prey in galicia, northwest spain. | this is a survey of the helminth fauna of 285 individuals of 14 species of birds of prey (falconiformes and strigiformes) from galicia (northwest spain), namely buteo buteo, accipiter nisus, a. gentilis, milvus migrans, m. milvus, pernis apivorus, circus pygargus, falco tinnunculus, f. peregrinus, f. subbuteo, tyto alba, strix aluco, asio otus and athene noctua. a total of 15 helminth species were detected, namely 8 nematodes ( eucoleus dispar, capillaria tenuissima, synhimantus laticeps, microt ... | 2004 | 14714181 |
| heavy metal (cd, pb, zn) and metalloid (as) content in raptor species from galicia (nw spain). | as top consumers in food chains, birds of prey forage over large geographical areas and so might be expected to accumulate environmental contaminants which are distributed in the environment. these wild animals can offer opportunities to detect and assess the toxicological effects of different inorganic elements on terrestrial ecosystems. in this study, different raptor species, both diurnal and nocturnal, were investigated for heavy metal (pb, cd and zn) and as concentrations in liver samples, ... | 2008 | 17617459 |
| occurrence of giardia and cryptosporidium in wild birds in galicia (northwest spain). | faecal samples were obtained from 433 wild birds being treated in wildlife recovery centres in galicia (northwest spain), between february 2007 and september 2009. the birds belonged to 64 species representing 17 different orders. giardia cysts and cryptosporidium oocysts were detected by an immunofluorescence antibody test and identified at the molecular level by established pcr-sequencing methods. the overall prevalence of giardia was 2·1% and that of cryptosporidium, 8·3%. to our knowledge, t ... | 2015 | 25669618 |
| supercritical fluid extraction of polycyclic aromatic hydrocarbons from liver samples and determination by hplc-fl. | an extraction/clean-up procedure by sfe was developed for isolating pahs from liver samples for subsequent hplc-fl determination of ten pahs in the enriched extract. recoveries (90-115%) and rsd % (< or =7.7) were satisfactory. when applied to 11 samples of bird of prey (tyto alba) protected species and classified of special interest, from the galicia (northwest to spain), benzo[ghi]perylene and indeno[1,2,3-cd]pyrene were undetectable; chrysene and benzo[a]pyrene are only detected in one sample ... | 2000 | 11225834 |
