北美被认为是一个可能受到全球变暖严重影响的地区，气候变化导致近几十年来美国冬季气温明显变暖。蜱对周围非生物条件的变化敏感，因此对气候敏感：它们是变温的，每个物种的生命阶段都需要特定的环境条件才能成功发展和生存。我们的综述集中在（1）确定和探索北美八种医学上重要的媒介蜱虫物种的合适区域;（2）探索物种的分布是否以及如何在未来几十年内应对气候变化而发生变化，以及以何种方式发生变化;（3）并提供从现在到未来北美蜱虫相关疾病的状况。 蜱虫在节肢动物媒介中传播给人类的传染因子数量很高，包括莱姆病、落基山斑疹热、科罗拉多蜱热、人单核细胞埃立克体病、兔热病和人粒细胞无形体病。温度升高被怀疑会影响蜱叮咬率和病原体发育率，从而可能增加疾病发生的风险。蜱虫的分布对气候变化有反应，但它们的地理范围在未来几十年将如何变化，以及这些变化如何转化为疾病发病率的变化，目前尚不清楚。在这项研究中，我们组装了相关的生态位模型的8种蜱的医学或兽医的重要性，在北美（硬蜱肩胛，I。太平洋岛cookei、变异革蜱Dermacentor variabilis、革蜱D. andersoni、美洲钝眼蜱Amblyomma americanum、A. maculatum和Rhipicephalus sanguineus），评估各自在当前和未来气候条件下的分布潜力。我们的目标是评估未来几十年物种分布是否以及如何应对气候变化。我们根据对北美蜱虫相关疾病的可能影响来解释这些模式。
North America is considered as an area likely to be significantly affected by global warming, with climate change causing markedly warmer winter temperatures in the United States in recent decades. Ticks are sensitive to changes in ambient abiotic conditions and, therefore, climate: they are poikilothermic, with the life stages of each species requiring specific sets of environmental conditions for successful development and survival. Our review focuses on (1) identifying and exploring suitable areas for the eight medically important vector tick species in North America; (2) exploring whether and how species’ distributions are likely to shift in coming decades in response to climate change, and in what ways; (3) and providing a picture on the status of the tick-associated diseases in North America from the present to the future. Ticks rank high among arthropod vectors in terms of numbers of infectious agents that they transmit to humans, including Lyme disease, Rocky Mountain spotted fever, Colorado tick fever, human monocytic ehrlichiosis, tularemia, and human granulocytic anaplasmosis. Increasing temperature is suspected to affect tick biting rates and pathogen developmental rates, thereby potentially increasing risk for disease incidence. Tick distributions respond to climate change, but how their geographic ranges will shift in future decades and how those shifts may translate into changes in disease incidence remain unclear. In this study, we have assembled correlative ecological niche models for eight tick species of medical or veterinary importance in North America (Ixodes scapularis, I. pacificus, I. cookei, Dermacentor variabilis, D. andersoni, Amblyomma americanum, A. maculatum, and Rhipicephalus sanguineus), assessing the distributional potential of each under both present and future climatic conditions. Our goal was to assess whether and how species’ distributions will likely shift in coming decades in response to climate change. We interpret these patterns in terms of likely implications for tick-associated diseases in North America.
