摘要: 1. Invasive species, such as feral pigs (Sus scrofa) are often ecologically harmful and have expanding distributions. Effectively reducing pig populations, which is becoming an increasingly common objective of wildlife managers, requires determining how reduction efforts affect vital rates rate potentially has the largest effect on population growth (λ). 2. We implemented a manipulative experiment populations at Fort Benning, Georgia to assess demographic effects lethal reduction. compared demography non-manipulated control with treatment population, where were experimentally removed. Using mark-recapture data from trapping, re-sight cameras, telemetry radio-collared pigs, hunter-returned tags, we estimated survival, recruitment, for 2004-2005. Matrix model analytical simulation sensitivity analyses used determine seasonal could contribute most changes in
