| new world origins for haemoparasites infecting united kingdom grey squirrels (sciurus carolinensis), as revealed by phylogenetic analysis of bartonella infecting squirrel populations in england and the united states. | phylogenetic analyses of bartonella have suggested divergence between bartonellae that infect mammals native to the old and new worlds. we characterized bartonella isolated from eastern grey squirrels (sciurius carolinensis) in the united states and from grey and red squirrels (sciurus vulgaris) in the united kingdom by nucleotide sequence comparison (glta and groel). isolates from grey squirrels in the united states and the united kingdom were identical, and most similar to bartonella vinsonii, ... | 2002 | 12558350 |
| bone assessment of free-living red squirrels (sciurus vulgaris) from the united kingdom. | metabolic bone disease has been reported in free-living red squirrels (sciurus vulgaris) in the united kingdom but the prevalence of this disease is unknown. in this study the bone quality of free-living red squirrels in the uk was assessed by radiology and bone densitometry. the study comprised 20 red squirrels found dead and submitted to the zoological society of london (uk) between 1997 and 1998, 10 were from the isle of wight (iow), where gray squirrels (sciurus carolinensis) are absent, and ... | 2004 | 15465719 |
| poxviral disease in red squirrels sciurus vulgaris in the uk: spatial and temporal trends of an emerging threat. | the squirrel poxvirus (sqpv) is the probable mediator of apparent competition between the introduced invading gray squirrel (sciurus carolinensis) and the red squirrel (sciurus vulgaris) in the uk, and modeling studies have shown that this viral disease has had a significant impact on the decline of the red squirrel in the uk. however, given our limited understanding of the epidemiology of the disease, and more generally the effects of invasive species on parasite ecology, there is a need to inv ... | 2008 | 18923872 |
| detection of squirrel poxvirus by nested and real-time pcr from red (sciurus vulgaris) and grey (sciurus carolinensis) squirrels. | squirrel poxvirus (sqpv) is highly pathogenic to red squirrels (sciurus vulgaris), and is a significant contributing factor to the local extinction of the species in most parts of england and wales, where infection is endemic in eastern grey squirrel (sciurus carolinensis) populations. although a nested pcr assay has been used successfully to study the epidemiology of sqpv, samples have a long processing time and the assay is not quantifiable. | 2010 | 20529323 |
| changes in the impact and control of an invasive alien: the grey squirrel (sciurus carolinensis) in great britain, as determined from regional surveys. | the grey squirrel, sciurus carolinensis gmelin, was introduced into sites in england, wales, scotland and ireland from the united states and canada between 1876 and 1929. soon after its introduction there were reports of damage to trees by seasonal bark stripping activity. surveys in state and private forests since 1954 have monitored their distribution and impacts. two surveys also gathered information on control efforts used to minimise damage. grey squirrel population range has expanded signi ... | 2013 | 23417829 |
