A taste for novelty in invading house sparrows, Passer domesticus
One of the central questions in invasion biology involves why some introductions succeed and others fail. Although several correlates of invasion success have been identified, patterns alone cannot identify the mechanisms underlying the invasion process. Here, we test the hypothesis that one predictor of invasion success, behavioral flexibility, is different between invading and established pop...
متن کاملA Survey of Neospora caninum infection in sparrows (Passer domesticus) in Khuzestan Province, Iran
The present study reports the presence of N. caninum DNA by PCR in brain tissues of house sparrows. The results showed that 6 (2.8%) of brain samples were positive for N. caninum. This is the first report for detection of N. caninum in sparrows, in Khuzestan Province. The results suggest that the meat of infected sparrows can be the source for dogs' infection.
متن کاملDispersal of introduced house sparrows Passer domesticus: an experiment.
An important issue concerning the introduction of non-indigenous organisms into local populations is the potential of the introduced individuals to spread and interfere both demographically and genetically with the local population. Accordingly, the potential of spatial dispersal among introduced individuals compared with local individuals is a key parameter to understand the spatial and tempor...
متن کاملIntracellular glucocorticoid receptors in spleen, but not skin, vary seasonally in wild house sparrows (Passer domesticus).
Over the short-term and at physiological doses, acute increases in corticosterone (CORT) titres can enhance immune function. There are predictable seasonal patterns in both circulating CORT and immune function across many animal species, but whether CORT receptor density in immune tissues varies seasonally is currently unknown. Using radioligand binding assays, we examined changes in concentrat...
متن کاملPrevalence and Genetic Characterization of Toxoplasma gondii in House Sparrows (Passer domesticus) in Lanzhou, China
The prevalence of Toxoplasma gondii infection in birds has epidemiological significance because birds are indeed considered as a good indicator of environmental contamination by T. gondii oocysts. In this study, the prevalence of T. gondii in 313 house sparrows in Lanzhou, northwestern China was assayed by the modified agglutination test (MAT). Antibodies to T. gondii were positive in 39 (12.46...
