“…House sparrows were introduced repeatedly into North America beginning in the 1850s (Robbins 1973) and are now widely dispersed and found mainly in peridomestic settings. Sparrows are semicolonial, often forming aggregations of 2 to 20 nests in proximity.…”

“…The first house sparrows probably invaded cliff swallow colonies in western Nebraska in about 1940, based on the sparrow's spread across North America (Robbins 1973) and when artificial swallow nesting structures (e.g., concrete bridges) near towns first appeared (Brown and Brown 1996). However, most sparrow use of swallow colonies in the study area has been more recent.…”

“…Within the last 50-150 years, the introduced house sparrow (Passer domesticus), a species native to Europe (Robbins 1973), has moved into cliff swallow colonies in many parts of North America, often usurping active swallow nests or occupying abandoned ones (Scott et al 1984, Brown et al 2009). In the process, house sparrows have been exposed to swallow bugs and BCRV.…”

Invasive species can disrupt natural disease dynamics by altering pathogen transmission among native hosts and vectors. The relatively recent occupancy of cliff swallow (Petrochelidon pyrrhonota) nesting colonies in western Nebraska by introduced European house sparrows (Passer domesticus) has led to yearly increases in the prevalence of an endemic arbovirus, Buggy Creek virus (BCRV), in its native swallow bug (Oeciacus vicarius) vector at sites containing both the invasive sparrow host and the native swallow host. At sites without the invasive host, no long-term changes in prevalence have occurred. The percentage of BCRV isolates exhibiting cytopathicity in Vero-cell culture assays increased significantly with year at sites with sparrows but not at swallow-only sites, suggesting that the virus is becoming more virulent to vertebrates in the presence of the invasive host. Increased BCRV prevalence in bug vectors at mixed-species colonies may reflect high virus replication rates in house sparrow hosts, resulting in frequent virus transmission between sparrows and swallow bugs. This case represents a rare empirical example of a pathogen effectively switching to an invasive host, documented in the early phases of the host's arrival in a specialized ecosystem and illustrating how an invasive species can promote long-term changes in host-parasite transmission dynamics.

“…House sparrows were introduced into North America from Europe in the late 1800's and are found in all parts of the United States (Robbins 1973;Lowther and Cink 1992). House sparrows usurp active cliff swallow nests and will occupy them until the nests fall from the substrate.…”

Isolation by distance explains genetic structure of Buggy Creek virus, a bird-associated arbovirus

et al. 2010

View full text Add to dashboard Cite

Many of the arthropod-borne viruses (arboviruses) show extensive genetic variability and are widely distributed over large geographic areas. Understanding how virus genetic structure varies in space may yield insight into how these pathogens are adapted to and dispersed by different hosts or vectors, the relative importance of mutation, drift, or selection in generating genetic variability, and where and when epidemics or epizootics are most likely to occur. However, because most arboviruses tend to be sampled opportunistically and often cannot be isolated in large numbers at a given locale, surprisingly little is known about their spatial genetic structure on the local scale at which host/vector/virus interactions typically occur. Here, we examine fine-scale spatial structure of two sympatric lineages of Buggy Creek virus (BCRV, Togaviridae), an alphavirus transmitted by the ectoparasitic swallow bug (Oeciacus vicarius) to colonially nesting cliff swallows (Petrochelidon pyrrhonota) and invasive house sparrows (Passer domesticus) in North America. Data from 377 BCRV isolates at cliff swallow colony sites in western Nebraska showed that both virus lineages were geographically structured. Most haplotypes were detected at a single colony or were shared among nearby colonies, and pair-wise genetic distance increased significantly with geographic distance between colony sites. Genetic structure of both lineages is consistent with isolation by distance. Sites with the most genetically distinct BCRV isolates were occupied by large numbers of house sparrows, suggesting that concentrations of invasive sparrows may represent foci for evolutionary change in BCRV. Our results show that bird-associated arboviruses can show genetic substructure over short geographic distances.

“…Deliberate introductions in other cities along with rapid population growth and unaided dispersal led to the species' spread across the continent by 1900 (Barrows 1889, Robbins 1973, Bennett 1990). When the House Sparrow invaded the native range of the House Finch, a species with which it shares urban habitat, in western North America, interference competition between the two species was observed (Bertgold 1913, Kalinoski 1975.…”

A Multi-Scale Analysis of Competition between the House Finch and House Sparrow in the Southeastern United States

2011

The decline of House Sparrow (Passer domesticus) populations in eastern North America has been proposed to be a consequence of competition between the House Sparrow and the House Finch (Carpodacus mexicamis), both introduced species. Previous research testing the hypothesis that House Sparrow declines are due to competition with House Finches focused on populations in the northeastern U.S., excluding other regions where the species coexist. We tested for effects of competition between these two species in the southeastern U.S. at two scales of analysis. First, we looked for evidence of competition at a local scale during the breeding season by examining patterns of co-occurrence of House Finches and House Sparrows at count points within a 28.3-km-study area centered on Auburn, Alabama. Second, we tested for the effects of competition at a regional scale across seven southeastern states by analyzing trends in Christmas Bird Count data. Using null-model analysis, we found no evidence for competitive exclusion in our assessment of local co-occurrence, suggesting that if there is competition between these species it is not important enough to affect their spatial distribution during the breeding season. At the regional scale, contrary to findings in the northeastern U.S., the decline of House Sparrow populations within the southeastern U.S. was not significantly correlated with House Finch abundance. Our results suggest that competition with House Finches is not a major cause of decline of the House Sparrow population in the southeastern U.S. Análisis de Competencia en Multiples Escalas entre Carpodacus mexicanus y Passer domesticus en el Sureste de Estados UnidosResumen. Se ha propuesto que la disminución de las poblaciones de Passer domesticus en el este de America del Norte es una consecuencia de la competencia entre P. domesticus y Carpodacus mexicanus, ambas especies introducidas. Investigaciones previas que evaluaron la hipótesis de que la disminución de P. domesticus es debida a la competencia con C. mexicanus se enfocaron en las poblaciones del noreste de EEUU, excluyendo otras regiones donde las especies coexisten. Evaluamos los efectos de la competencia entre estas dos especies en el sudeste de EEUU, considerando dos escalas de análisis. Primero, buscamos evidencia de competencia a escala local durante la estación reproductiva mediante el examen de patrones de co-ocurrencia de C. mexicanus y P. domesticus en puntos de conteo dentro de un área de estudio de 28.3 km-centrada en Auburn, Alabama. Segundo, evaluamos los efectos de la competencia a escala regional a través de siete estados del sudeste mediante el análisis de las tendencias en los datos del Conteo de Aves de Navidad. Usando análisis de modelos nulos, no encontramos evidencia de exclusión competitiva en nuestra evaluación de co-ocurrencia local, sugiriendo que si hay competencia entre estas especies no es de una importancia suficiente como para afectar su distribución espacial durante la estación reproductiva. A escala regional, contrariamente a lo...
