由非本地物种引入的传染病越来越多地被认为是本地人口下降的促进因素，但由于爆发周围的人口和疾病流行数据不足，可能缺乏直接证据。先前的间接证据和理论模型支持松鼠痘病毒（SQPV）可能参与了红松鼠（Sciurus vulgaris）在引入非本地灰松鼠（Sciurus carolinensis）到英国后的衰落。红松鼠是英国的一个主要保护问题，了解它的持续下降对于任何缓解下降的尝试都很重要。红松鼠-灰松鼠系统也是传染病（表观竞争）和直接竞争之间相互作用的典范，这种相互作用推动了入侵物种取代本地物种。默西塞德郡的松鼠丰度和松鼠痘病（SQPx）的发病率的时间序列数据，以确定病原体和非本地物种对本地红松鼠种群的影响。分析表明，红松鼠的SQPx对松鼠密度和种群增长率（PGR）有显着的负面影响。几乎没有证据表明灰松鼠的直接影响;只有灰松鼠的存在（而不是密度）被证明会影响红松鼠的密度，但不会影响红松鼠的PGR。红色SQPx病例的动态在很大程度上取决于以前的红色SQPx病例，尽管以前感染当地灰松鼠也有特征，因此，SQPV感染的灰松鼠被确定为可能在红松鼠中引发SQPx爆发。回顾性血清学研究表明，约8%的红松鼠接触SQPV可能会在流行期间感染后存活。这项研究进一步强调了英国红松鼠-灰松鼠系统作为一个典型的例子，本地物种的人口下降强烈促进了传染病引入的非本地物种。因此，至关重要的是，疾病预防和控制措施是在英国保护红松鼠的努力中不可或缺的。
Infectious disease introduced by non-native species is increasingly cited as a facilitator of native population declines, but direct evidence may be lacking due to inadequate population and disease prevalence data surrounding an outbreak. Previous indirect evidence and theoretical models support squirrelpox virus (SQPV) as being potentially involved in the decline of red squirrels (Sciurus vulgaris) following the introduction of the non-native gray squirrel (Sciurus carolinensis) to the United Kingdom. The red squirrel is a major UK conservation concern and understanding its continuing decline is important for any attempt to mitigate the decline. The red squirrel–gray squirrel system is also exemplary of the interplay between infectious disease (apparent competition) and direct competition in driving the replacement of a native by an invasive species. Time series data from Merseyside are presented on squirrel abundance and squirrelpox disease (SQPx) incidence, to determine the effect of the pathogen and the non-native species on the native red squirrel populations. Analysis indicates that SQPx in red squirrels has a significant negative impact on squirrel densities and their population growth rate (PGR). There is little evidence for a direct gray squirrel impact; only gray squirrel presence (but not density) proved to influence red squirrel density, but not red squirrel PGR. The dynamics of red SQPx cases are largely determined by previous red SQPx cases, although previous infection of local gray squirrels also feature, and thus, SQPV-infected gray squirrels are identified as potentially initiating outbreaks of SQPx in red squirrels. Retrospective serology indicates that approximately 8% of red squirrels exposed to SQPV may survive infection during an epidemic. This study further highlights the UK red squirrel – gray squirrel system as a classic example of a native species population decline strongly facilitated by infectious disease introduced by a non-native species. It is therefore paramount that disease prevention and control measures are integral in attempts to conserve red squirrels in the United Kingdom.
