鉴于当前气候快速变化的时期，了解物种改变其地理范围的能力非常重要。此外，需要更好地了解范围变化背后的空间人口动态，以补充气候生态位建模所取得的进展。开发了一个模拟模型，该模型包含了在范围变化动力学研究中很大程度上被忽视的三个关键特征：种内竞争的形式、依赖于密度的扩散和栖息地斑块的瞬时动态。结果表明，响应的确切形状很大程度上取决于局部和斑块动态。种内竞争以竞争为基础的物种比那些以争夺为基础的竞争的物种更容易受到伤害。当与密度相关的分散相结合时，参赛者尤其敏感。生活在承载能力增长缓慢的斑块中的物种也容易受到环境条件快速变化的影响。补充分析方法进一步强调了种内竞争的重要性。
Understanding the ability of species to shift their geographic range is of considerable importance given the current period of rapid climate change. Furthermore, a greater understanding of the spatial population dynamics underlying range shifting is required to complement the advances made in climate niche modelling. A simulation model is developed which incorporates three key features that have been largely overlooked in studies of range shifting dynamics: the form of intraspecific competition, density dependent dispersal and the transient dynamics of habitat patches. The results show that the exact shape of the response depends critically on both local and patch dynamics. Species whose intraspecific competition is contest based are more vulnerable than those whose competition is scramble based. Contesters are especially sensitive when combined with density dependent dispersal. Species living in patches whose carrying capacity grows slowly are also susceptible to rapid shifts of environmental conditions. A complementary analytic approach further highlights the importance of intraspecific competition.
