Streptopelia Decaocto Research Articles

First detection of Arcobacter sp. in Eurasian collared doves (Streptopelia decaocto).

Data about the presence of Arcobacter in wild birds are currently lacking. In this study cloacal swabs from 95 collared doves (Streptopelia decaocto), submitted to the Department of Veterinary Medical Sciences (Bologna, Italy) between 2011 and 2013 from various urban and suburban areas of the Emilia-Romagna region (Northern Italy), were tested for the presence of Arcobacter sp. by a rRNA 23S nested Polymerase Chain Reaction (PCR). Eighteen out of 95 (19%) samples showed the expected PCR product. Further cultural and molecular studies are needed to assess the Arcobacter prevalence in wild birds and elucidate their potential epidemiological role as source of animal and human infections.

Range expansion and population dynamics of an invasive species: the Eurasian Collared-Dove (Streptopelia decaocto).

Invasive species offer ecologists the opportunity to study the factors governing species distributions and population growth. The Eurasian Collared-Dove (Streptopelia decaocto) serves as a model organism for invasive spread because of the wealth of abundance records and the recent development of the invasion. We tested whether a set of environmental variables were related to the carrying capacities and growth rates of individual populations by modeling the growth trajectories of individual populations of the Collared-Dove using Breeding Bird Survey (BBS) and Christmas Bird Count (CBC) data. Depending on the fit of our growth models, carrying capacity and growth rate parameters were extracted and modeled using historical, geographical, land cover and climatic predictors. Model averaging and individual variable importance weights were used to assess the strength of these predictors. The specific variables with the greatest support in our models differed between data sets, which may be the result of temporal and spatial differences between the BBS and CBC. However, our results indicate that both carrying capacity and population growth rates are related to developed land cover and temperature, while growth rates may also be influenced by dispersal patterns along the invasion front. Model averaged multivariate models explained 35–48% and 41–46% of the variation in carrying capacities and population growth rates, respectively. Our results suggest that widespread species invasions can be evaluated within a predictable population ecology framework. Land cover and climate both have important effects on population growth rates and carrying capacities of Collared-Dove populations. Efforts to model aspects of population growth of this invasive species were more successful than attempts to model static abundance patterns, pointing to a potentially fruitful avenue for the development of improved invasive distribution models.

Incremento en la distribución y primer registro de anidación de la paloma de collar (Streptopelia decaocto) en la península de Baja California, México

We report the presence of Eurasian collared-dove Streptopelia decaocto in many towns, villages and ranches of Baja California Peninsula. Our first record was in fall 2008 and since then, we have found an increase in number and distribution of this dove in several locations of the peninsula, with presence in 64% of the total human settlements we surveyed throughout the peninsula (N= 100). We also present information on the first 2 active nests in Baja California Sur. Eurasian collared-dove is breeding in the Baja California Peninsula at the present and is increasing its distribution into the peninsula tightly linked to human altered habitats.

Chlamydiosis in British Garden Birds (2005-2011): retrospective diagnosis and Chlamydia psittaci genotype determination.

The significance of chlamydiosis as a cause of mortality in wild passerines (Order Passeriformes), and the role of these birds as a potential source of zoonotic Chlamydia psittaci infection, is unknown. We reviewed wild bird mortality incidents (2005–2011). Where species composition or post-mortem findings were indicative of chlamydiosis, we examined archived tissues for C. psittaci infection using PCR and ArrayTube Microarray assays. Twenty-one of 40 birds tested positive: 8 dunnocks (Prunella modularis), 7 great tits (Parus major), 3 blue tits (Cyanistes caeruleus), 2 collared doves (Streptopelia decaocto, Order Columbiformes), and 1 robin (Erithacus rubecula). Chlamydia psittaci genotype A was identified in all positive passerines and in a further three dunnocks and three robins diagnosed with chlamydiosis from a previous study. Two collared doves had genotype E. Ten of the 21 C. psittaci-positive birds identified in the current study had histological lesions consistent with chlamydiosis and co-localizing Chlamydia spp. antigens on immunohistochemistry. Our results indicate that chlamydiosis may be a more common disease of British passerines than was previously recognized. Wild passerines may be a source of C. psittaci zoonotic infection, and people should be advised to take appropriate hygiene precautions when handling bird feeders or wild birds.Electronic supplementary materialThe online version of this article (doi:10.1007/s10393-014-0951-x) contains supplementary material, which is available to authorized users.

Breeding biology of domesticated Eurasian Collared Dove (Columbidae) Streptopelia decaocto Frivaldszky 1838 in Saidpur, Bangladesh

Two pairs of domesticated Eurasian Collared Dove Streptopelia decaocto reared at eighteen months for its breeding performance in intensive system. One pair was homozygous albino al//al x al//al and another pair was one wild type +//al and another albino al//al. Another experimented four pairs of doves were produced from these two pairs. Out of six pairs total 114 squabs were produced during the research period. Total three albino pairs produced 100% albino squab and different coloured male and female produced different colours which were 50% each. Sex ratio of male and female were observed 1:1. Experimental doves were reared in cages measures 23x20x16 and 25x22x18 inches and feed were supplied all day long with wheat, corn, mustard, broken rice and burnt soil. Intake feed were 15 gram per dove in a day. During the time of this observation only hypervitaminosis and worm infestations were observed and the mortality rate was few. Only in one pair (rosy ? x wild type ?) produced 11 male (46%) and 13 female (54%) out of 24 squabs; this was slightly exceptional. In total 114 squabs from six pairs only one rosy male and pied rosy female were found. Breeding record of this research suggests that the colour patterns are first wild type then rosy and finally albino gradually.DOI: http://dx.doi.org/10.3126/ije.v3i2.10571 International Journal of the Environment Vol.3(2) 2014: 48-54

Range Expansion and Population Dynamics of an Invasive Species: The Eurasian Collared-Dove (Streptopelia decaocto)

Preliminary Molecular Variability of Some Dove Species Inhabiting Saudi Arabia

Approximately 800 bp of the mitochondrial 12S rRNA gene were sequenced for the Eurasian collared-dove Streptopelia decaocto and the African collared-dove Streptopelia roseogrisea. The first species was collected from Taif at the eastern boarder of Sarawat mountains and from Jazan at the southwest, while the second was collected from Taif only. These obtained sequences were used to study the genetic variability between the two species. The base differences between the two species were 19 sites along the sequenced fragment, while there was no intra-specific difference. It is therefore noteworthy to conclude that the Eurasian dove is homogenous along the range of distribution throughout Sarawat mountains and the small variability between the two dove species is indicative to their morphological and genetic similarity.

Experimental infection of Eurasian collared-dove (Streptopelia decaocto) with West Nile virus

The Eurasian collared-dove (Streptopelia decaocto) has recently experienced a population explosion in North America. It is frequently infected with West Nile virus (WNV). To test the hypothesis that the Eurasian collared-dove is competent to transmit WNV, we experimentally infected two cohorts of doves with two different strains of WNV, CO08, and NY99, respectively. Both virus strains induced a low-level viremia, capable of infecting a small fraction of vector mosquitoes. We suggest that the Eurasian collared-dove plays a relatively insignificant role as an amplifying host for WNV, but it may be important where it is locally abundant.

Isolation and Identification of Bacteria from Genital Organs of Pigeons

This study includes an examination of 70 bacterial swabs taken from ovary, oviduct of femal and male testis from adult pigeons of species Collard dove (Streptopelia decaocto), from December 2010 to June 2011. The pigeons were clinically healthy. The isolates were 12 species and 21 types of bacteria. The type Staphylococcus xylosus was highest ratio (11.7%) and types Micrococcus luteus and Gallibacterium anatis were lowest ratio (1.8%). Other isolates of bacteria were distributed between these two percentages. Regarding the isolate site, the highest isolation ratio of ovarian swabs was Enterococcus durans and Bacillus subtilis (12%), while the higher bacteria ratio isolated from the oviduct swabs are En. avium, Escherichia coli and Pasteurella multocida (9%), the testicular swabs were Staph. xylosus most isolation ratio (20%), while isolate each of species Pseudomonas aeruginosa, Staph. xylosus, Staph. saprophyticus, En. faecalis and E. coli of swabs taken in the case of ovulation from female pigeons, has also investigated some of the Virulence factors which are possessed by these isolates such as Urease, DNase, Gelatinase and Haemolysin, the study found that these isolates have some of these factors.

Molecular classification of Pakistani collared dove through DNA barcoding

Pakistan is bestowed by a diversified array of wild bird species including collared doves of which the taxonomy has been least studied and reported. DNA barcoding is a geno-taxonomic tool that has been used for characterization of bird species using mitochondrial cytochrome c oxidase I gene (COI). This study aimed to identify taxonomic order of Pakistani collared dove using DNA barcoding. Purposely herein, we present a phylogenetic analysis of Pakistani collared dove based on 650 base pairs of COI gene sequences. Analysis of phylogenetic tree revealed that Pakistani collared dove shared a common clade with Eurasian collared dove (Streptopelia decaocto) and African collared dove (Streptopelia roseogrisea) which indicated a super-species group in Streptopelia genus. This is the first report of molecular classification of Pakistani collared dove using DNA barcoding.

Bird Species Diversity of the Mitidja Plain (Northern Algeria) with Emphasis on the Dynamics of Invasive and Expanding Species

Abstract This treatise investigates the poorly studied bird fauna of Mitidja Plain (Northern Algeria), with particular notes on the occurrence and expansion of new and alien species. Direct observations, supported by ornithological surveys carried out by Progressive Frequential Sampling (PFS), a version of a point count method, have allowed us to identify 125 bird species. These represent 31% of all species known from Algeria. The species recorded belong to 14 orders, 39 families and 37 genera. According to their biogeographic origins, 36 are Mediterranean, 32 Palearctic, 24 Holarctic, 17 European and 16 of European-Turkestani origin. The Mitidja Plain holds 60 resident-breeder species (48% of all registered species) and is a transit zone for many migratory species (summer and winter migrants constituting 20% and 14% of the total, respectively) and occasional visitors (RA = 12%). Among recently expanding species (introduced or local), the Collared Dove Streptopelia decaocto and Wood Pigeon Columba palumbus, sampled by the spot-mapping method, experienced a very rapid population growth. The first observations of the former were made in 1996 in Algiers. Its numbers experienced a steep increase after 2002, starting from 5.75 pairs/10 ha to reach up to 31.5 pairs/10 ha in 2006. The same applies for the Rose-ringed Parakeet Psittacula krameri, surveyed by direct-count at roosting sites. This species has been able to increase and reproduce since its first introduction into the wild in 1996. The increase in study species populations, especially the Rose-ringed Parakeet, may derive from good weather conditions that favoured the species through providing better feeding conditions, thus high reproduction outcomes.

COI barcodes and phylogeny of doves (Columbidae family)

Cytochrome oxidase subunit I (COI) gene has been recognized as an authentic tool for species identification. Besides its potential barcoding capacity, COI sequences have also been used for inferring the phylogeny. Phylogenetic relationships among genera of Columbidae (pigeons and doves family) have not been fully resolved because of scarce sampling of taxa and limited availability of sequence data. In this study, we have evaluated the efficiency of COI barcodes for species identification and phylogenetic analysis of various doves. We sequenced the 693 bp region of COI gene of three species of doves including Oena capensis, Streptopelia decaocto, and Streptopelia senegalensis. After retrieving the relevant sequences from the GenBank, the entire data-set of 85 sequences represented 25 dove species from 11 different genera of the family Columbidae. The COI sequences of four species including Chalcophaps indica (two specimens), Columbina inca (five specimens), Geopelia striata (three specimens), and Macropygia phasianella (three specimens) were identical. The mean intraspecific base differences ranged from 0 to 37 while the P-distances ranged between 0 and 0.058. For most of the species, the P-distances were ≤ 0.008. Phylogenetic analysis differentiated the taxa into three major clusters. One of the clusters grouped five genera including Claravis, Columbina, Gallicolumba, Geopelia, and Geotrygon. The remaining two clusters grouped three genera each including Chalcophaps, Oena, and Turtur in one cluster and Macropygia, Streptopelia, and Zenaida in another cluster. Further sub-clustering clearly separated all the genera into individual clusters except two discrepancies for the genera Streptopelia and Turtur. Species-level cladistics clearly separated all the species into distinctive clades. In conclusion, COI barcoding is a powerful tool for species identification with added information on phylogenetic inference. The finding of this study will help to understand the complex phylogeny of the family Columbidae.

In vitro biology of Columbicola bacillus (Phthiraptera: Ischnocera)

An ischnoceran louse, Columbicola bacillus infesting Ring dove, Streptopelia decaocto was subjected to in vitro experimentation. The data obtained through in vitro experimentation was utilized to construct the life table and to determine its intrinsic rate of natural increase (rm). The value of rm appeared to be 0.054. At this rate, the population of C. bacillus is supposed to be double after 12.95 days, indicating that it is moderate breeder.

West Nile Virus in North‐Eastern Italy, 2011: Entomological and Equine IgM‐Based Surveillance to Detect Active Virus Circulation

Since 2008, West Nile Virus (WNV) has expanded its range in several Italian regions, and its yearly recurrence suggests the virus may have become endemic in some areas. In 2011, a new plan based also on the detection of IgM antibodies was implemented in the north-eastern Italian regions of Veneto and Friuli Venezia Giulia, aiming to early detect WNV infections in areas where the virus had already circulated during the previous summers, and in adjacent zones. From July to November 2011, 1880 sera from 521 equine premises were screened by a commercial IgM capture ELISA. Mosquitoes were captured by CDC-CO2 traps at 61 locations in the two regions. Collected mosquitoes were identified, pooled by species/date/location and examined by real-time RT-PCR and sequencing. Passive surveillance was carried out on clinically affected horses and non-migratory wild birds found dead. IgM sero-positive equines were detected in 19 holdings, five in the area with WNV circulation (AWC) and 14 in the surveillance area (SA); 10 more horse premises tested positive to further serological controls within 4 km of the positive holdings. A total of 85,398 mosquitoes of 15 species were collected and 2732 pools examined. Five Culex pipiens pools tested positive for the presence of WNV. Passive surveillance on non-migratory wild birds allowed detection of the virus only in one found dead collared dove (Streptopelia decaocto), of 82 birds sampled. The WNV belonged to the lineage 2, which had been isolated for the first time in Italy earlier in 2011. By the first week of October, nine human cases had been confirmed in the same area. The implementation of a protocol combining IgM screening of horses with surveillance on mosquito vectors proved to be valuable for early detecting WNV circulation.

Expansion of an Exotic Species and Concomitant Disease Outbreaks: Pigeon Paramyxovirus in Free-Ranging Eurasian Collared Doves

Eurasian collared doves (Streptopelia decaocto) have expanded their range across the United States since their introduction several decades ago. Recent mortality events in Eurasian collared doves in Arizona and Montana, USA, during the winter of 2009-2010 were the result of pigeon paramyxovirus (PPMV), a novel disease agent. The first instance of mortality by this emerging infectious disease in this species occurred in Florida in 2001 with subsequent disease events in 2006 and 2008. Full diagnostic necropsies were performed on carcasses from the three states. PPMV was identified by RT-PCR and virus isolation and was sequenced to the VIb genotype of avian paramyxovirus-1 (APMV). Other APMVs are common in a variety of free-ranging birds, but concern is warranted because of the potential for commingling of this species with native birds, virus evolution, and threats to domestic poultry. Improved surveillance for wildlife mortality events and efforts to prevent introduction of non-native animals could reduce the threat of introducing new pathogens.
