| evidence of cryptic species in the genus tinaminyssus (acari: rhinonyssidae) based on morphometrical and molecular data. | the study of cryptic species allows to describe and to understand biodiversity, and the evolutionary processes shaping it. mites of the family rhinonyssidae are permanent parasites of the nasal cavities of birds, currently including about 500 described species and 12 genera. here, we tested the hypothesis that mites from five populations of the genus tinaminyssus-three isolated from european turtle doves (streptopelia turtur), and two from eurasian collared doves (streptopelia decaocto; aves: co ... | 2018 | 29876760 |
| high prevalence of trichomonas gallinae in wild columbids across western and southern europe. | avian trichomonosis is known as a widespread disease in columbids and passerines, and recent findings have highlighted the pathogenic character of some lineages found in wild birds. trichomonosis can affect wild bird populations including endangered species, as has been shown for mauritian pink pigeons nesoenas mayeri in mauritius and suggested for european turtle doves streptopelia turtur in the uk. however, the disease trichomonosis is caused only by pathogenic lineages of the parasite trichom ... | 2017 | 28521843 |
| novel avian oropharyngeal trichomonads isolated from european turtle doves (streptopelia turtur) and racing pigeons (columba livia): genetic and morphometric characterisation of clonal cultures. | extensive diversity has been described within the avian oropharyngeal trichomonad complex in recent years. in this study we developed clonal cultures from four isolates selected by their different its1/5.8s/its2 (its) genotype and their association with gross lesions of avian trichomonosis. isolates were obtained from an adult racing pigeon and a nestling of eurasian eagle owl with macroscopic lesions, and from a juvenile wood pigeon and an european turtle dove without clinical signs. multi-locu ... | 2017 | 28864154 |
| an avifaunal survey of mesic manmade ecosystems "oases" in algerian hot-hyperarid lands. | man made ecosystems of dry lands are key habitats due to their ecological characteristics to survey biodiversity. this study investigated bird diversity in three oases of the northern algerian sahara (i.e., biskra in 2006, oued souf in 2008 and ouargla in 2009), by using the spot-mapping method. bird density "d" (pairs/10 ha), species richness "s" (number species), diversity (shannon index) "h'" (in bits), and evenness "e" varied from one oasis to another (biskra: d = 98.5, s = 47, h' = 4.49, e ... | 2013 | 23961217 |
| color plumage polymorphism and predator mimicry in brood parasites. | plumage polymorphism may evolve during coevolution between brood parasites and their hosts if rare morph(s), by contravening host search image, evade host recognition systems better than common variant(s). females of the parasitic common cuckoo (cuculus canorus) are a classic example of discrete color polymorphism: gray females supposedly mimic the sparrowhawk (accipiter nisus), while rufous females are believed to mimic the kestrel (falco tinnunculus). despite many studies on host responses to ... | 2013 | 23663311 |
| trichomonad parasite infection in four species of columbidae in the uk. | trichomonas gallinae is an emerging pathogen in wild birds, linked to recent declines in finch (fringillidae) populations across europe. globally, the main hosts for this parasite are species of columbidae (doves and pigeons); here we carry out the first investigation into the presence and incidence of trichomonas in four species of columbidae in the uk, through live sampling of wild-caught birds and subsequent pcr. we report the first known uk cases of trichomonas infection in 86% of european t ... | 2013 | 23866933 |
| the protozoan parasite trichomonas gallinae causes adult and nestling mortality in a declining population of european turtle doves, streptopelia turtur. | studies incorporating the ecology of clinical and sub-clinical disease in wild populations of conservation concern are rare. here we examine sub-clinical infection by trichomonas gallinae in a declining population of free-living european turtle doves and suggest caseous lesions cause mortality in adults and nestlings through subsequent starvation and/or suffocation. we found a 100% infection rate by t. gallinae in adult and nestling turtle doves (n = 25) and observed clinical signs in three adul ... | 2015 | 25212735 |
| genetic characterization of oropharyngeal trichomonad isolates from wild birds indicates that genotype is associated with host species, diet and presence of pathognomonic lesions. | oropharyngeal trichomonad isolates of wild birds from spain were studied. a total of 1688 samples (1214 of predator birds and 474 of prey species) from wildlife recovery centres and scientific bird-ringing campaigns were analysed from 2011 to 2013. the overall infection prevalence was 20.3% (11.4% in predator birds and 43.3% in prey species). pathognomonic lesions were present in 26% of the infected birds (57.3% in predator birds and 4.9% in prey species). the most commonly parasitized species w ... | 2014 | 25262786 |

| trichomonas infection in a community of free-ranging domestic and wild columbiformes and bonelli's eagle (aquila fasciata). | trichomonas gallinae is a pathogen of conservation relevance, whose main maintenance hosts are columbiformes, but spillover to avian predators has been described. the goal of this study was to characterize the epidemiology of trichomonas spp. in a community of free-ranging domestic and wild columbiformes and an endangered predator, bonelli's eagle aquila fasciata. we surveyed 253 live-captured rock doves, 16 nestling bonelli's eagles and 41 hunted columbiformes. oro-esophageal swabs were incubat ... | 2019 | 31192234 |
| lead in terrestrial game birds from spain. | we analysed exposure to pb and its relationship with lead-based ammunition in seven species of terrestrial game birds-common woodpigeon (columba palumbus), rock dove (columba livia), stock dove (columba oenas), european turtle-dove (streptopelia turtur), red-legged partridge (alectoris rufa), barbary partridge (alectoris barbara) and common quail (coturnix coturnix)-from rural and urban areas in different parts of spain (valencia, castilla-la mancha, castilla y león, madrid, islas canarias and n ... | 2020 | 31755055 |
| migration routes and staging areas of trans-saharan turtle doves appraised from light-level geolocators. | the identification of migration routes, wintering grounds and stopover sites are crucial issues for the understanding of the palearctic-african bird migration system as well as for the development of relevant conservation strategies for trans-saharan migrants. using miniaturized light-level geolocators we report a comprehensive and detailed year round track of a granivorous trans-saharan migrant, the european turtle dove (streptopelia turtur). from five recovered loggers, our data provide new in ... | 2013 | 23544064 |
| genomic evidence of demographic fluctuations and lack of genetic structure across flyways in a long distance migrant, the european turtle dove. | understanding how past climatic oscillations have affected organismic evolution will help predict the impact that current climate change has on living organisms. the european turtle dove, streptopelia turtur, is a warm-temperature adapted species and a long distance migrant that uses multiple flyways to move between europe and africa. despite being abundant, it is categorized as vulnerable because of a long-term demographic decline. we studied the demographic history and population genetic struc ... | 2016 | 27821052 |
| exploring the relationship between brain plasticity, migratory lifestyle, and social structure in birds. | studies in passerines have found that migrating species recruit more new neurons into brain regions that process spatial information, compared with resident species. this was explained by the greater exposure of migrants to spatial information, indicating that this phenomenon enables enhanced navigational abilities. the aim of the current study was to test this hypothesis in another order-the columbiformes - using two closely-related dove species-the migrant turtle-dove (streptopelia turtur) and ... | 2017 | 28396621 |
