Estimating the strength of niche conservatism is key for predictions of invasion risk. Most studies consider only the climatic niche, but other factors, such as human disturbance, also shape niches. Whether occupation of human habitats in the alien range depends on the native tolerances of species remains unexplored. We assessed niche conservatism in climatic and human spaces for bird species showing different responses to humans in native ranges and evaluated whether considering anthropogenic niche variables affects invasion predictions.

人类对生态位变化的影响的全球评估以及鸟类入侵的风险预测

估计利基保守性的强度是预测入侵风险的关键。大多数研究仅考虑气候利基，而其他因素（例如人为干扰）也会影响生态位。在外星人范围内人类栖息地的占用是否取决于物种的天然耐受性尚待探索。我们评估了在气候和人类空间中鸟类物种的生态位保守性，该鸟类对本地范围内的人类表现出不同的反应，并评估了考虑人为生态位变量是否会影响入侵预测。
