Most raptors are flagship and umbrella species acting as ecosystem engineers. Research on avian parasites in is therefore of interest. There a lack studies Sarcocystis naturally infected raptors. In the present work, we aimed to identify spp. intestinal scrapings from Spain. were identified 82.5% samples studied by nested PCR sequencing partial ITS1 region 28S rRNA. A total nine known species, S. arctica, columbae, cornixi, glareoli, halieti, kutkienae, cf strixi, turdusi, sp. ex Corvus...
Members of the genus Sarcocystis are protozoan parasites characterized by a prey-predator two-host life-cycle. Sarcocysts formed in muscles or central nervous system intermediate host (IH), while sporocysts develop small intestine definitive (DH). Various birds prey have been confirmed to be DH for spp. Three species, S. wobeseri, halieti and falcatula, identified prey, which latter known pathogenic can cause encephalitis various birds. The aim this study was identify from Spain.Between 2019...
We investigated breeding densities and distribution of the woodpigeon Columba palumbus in woodland urban habitats Lithuania, Belarus Kaliningrad oblast (administrative district) Russia. In Lithuania Belarus, where urbanisation process is an initial phase, are higher than areas. Russia, abundant populations have been established towns for decades, significantly sites. Available data indicate that at present eastern border European well-established extends approximately along western Ukraine.
The viviparous lizard Lacerta (Zootoca) vivipara exhibits several alleles of the mannose‐6‐phosphate isomerase (MPI) enzyme that are carried exclusively on female W sex‐chromosome. Previous studies showed both oviparous and forms L. have these sex‐linked alleles. We document existence geographic variation among populations southwestern France northwestern Spain. Two subgroups were identified: all females from eastern central Pyrenees most Aquitaine northern slope western exhibited fast...
The lizard Lacerta vivipara has both oviparous and viviparous populations. Experimental crossbreedings (oviparous strain × strain) in the laboratory have previously allowed us to obtain a hybrid strain. Hybrids also laid eggs laboratory. aim of present study was determine eggshell characteristics compare them with studied strains. mean thickness is 21 μm for hybrid, 40 eggshell, 9 membrane. Mean dry mass 3 mg hybrids, 5 strain, 0.6 Ash 0.79 1.05 0.22 Fibrils were observed hybrids' eggshells...
A Columbidae species-specific primer pair PAL-2 was constructed. It based on the alignment of available GenBank sequences homological D-loop fragments Columbia livia, Columba janthina, junoniae and bollii. Using these newly developed primers, Woodpigeons (Columba palumbus) from wintering breeding populations southern Europe population eastern Baltic region were examined by sequencing 368 bp mtDNA fragments. In total, 31 different haplotypes detected among 89 sampled in 13 found 33 birds...
The attempt to identify the flyways of Woodpigeon (Columba palumbus) was made by means genetic analysis. Samples for study were collected in different breeding and wintering habitats (in Portugal, France, Spain, Germany, Sweden, Poland, Hungary, Latvia Lithuania) Woodpigeons. Five polymorphic loci controlling synthesis five liver proteins (Mc, Tf, PreTf, PostAl, PreAl) fragments randomly amplified DNA obtained using ten random primers explored during study. Significant differences based on...
The European Turtle Dove, Streptopelia turtur, a long-distance migrant wintering in Africa, is widespread Palearctic species. This species classified as vulnerable and undergoing long-term demographic decline. results of the previous study (based on mitochondrial (mtDNA) cytochrome-b (cytb) sequences birds from Western Southern Europe) indicated that was not genetically structured. We analysed mtDNA cytb D-loop 258 collected Morocco, Spain, Ukraine. High genetic variability, expressed by...
Male reproductive and fat body cycles were studies both in a mountain lowland population of the lizard Lacerta monticola cantabrica. Specimens collected at two localities Asturias (Northern Spain): Vegadeo (100 m a.s.l.) Aramo (1450 a.s.l.). General patterns spermatogenesis populations similar, agree with mixed type proposed by Saint Girons (1963). Spermatogenesis testicular growth start August spermiogenesis begins early autumn; before hibernation (October) ceases earlier than population....
Populations of common quail (Coturnix coturnix) have recently been declining in Europe. This is the first study eastern Europe using molecular markers. The mtDNA D-loop genetic diversity quails migrating through Ukraine was analyzed and compared with that birds via northern Spain 2017-2018. In samples from 77 birds, 32 polymorphic sites 30 haplotypes (H1-H30) were identified, only 4 which for sampled both Spain. Phylogenetic analysis indicated 2 well-supported clades. Found 3 clustered 1...
Abstract Background: Members of the genus Sarcocystis are protozoan parasites characterized by a prey-predator two-host life cycle. Sarcocysts formed in muscles or CNS intermediate host (IH), while sporocysts develop small intestine definitive (DH). Various birds prey were confirmed to be DH for spp. By contrast, only two species, S . wobeseri and falcatula identified prey. The latter species is pathogenic can cause encephalitis various birds. aim present study was identify from Spain....
