Mountains have provided important insights on the impacts of climate change on species distribution. Organisms living in tropical mountains are expected to specialize in narrow temperature limits (demonstrating low thermal tolerance), often with narrow elevational distributions relative to temperate species, and may shift their elevational range in response to climate change. Importantly, insects are sensitive, and respond rapidly, to temperature variation, making them suitable bioindicators to monitor the effects of climate change. However, to monitor the effects of climate change in mountains it is important to understand present elevational distribution and other ecological characteristics of local insect populations. In this context, we suggest a method to identify beetle taxa that can be used to monitor climate change effects in tropical mountainous insect species. We illustrate the method by describing the elevational distribution of different beetle groups, associating this distribution with species’ thermal range in a tropical mountain forest in Southeast Brazil. Sampling was conducted at Serra dos Órgãos National Park, RJ, Brazil, in the Atlantic Rainforest, one of the main global biodiversity hotspots. In order to systematically sample beetle diversity across elevations, we used flight interception ‘Malaise’ traps at fifteen different sites, from 130 m to 2170 m a.s.l., over three consecutive months during the rainy season. To investigate species’ climatic niches, we recorded climatic variables for this period. We collected 2963 individuals of 272 species, belonging to six Coleoptera groups over a temperature gradient that decreased about 0.5 °C for each 100 m in elevation. Considering the thermal tolerance of species from tropical mountains and their narrow elevational range and abundance, five Coleoptera species belonging to Cerambycidae, Eumolpinae (Chrysomelidae), Lampyridae and Phengodidae were considered suitable bioindicators, and the Eumolpinae and Lampyridae were the ones with the narrowest elevational range. We suggest that the use of abundant species (or groups of species) with narrow elevational range as bioindicators can be valuable to monitor the effects of climate change on the biota, allowing us to evaluate how species are responding to changes over time.

山区为气候变化对物种分布的影响提供了重要见识。预计生活在热带山区的生物将专注于狭窄的温度极限（表现出低的热耐受性），相对于温带物种，它们的海拔分布通常较窄，并且可能会随着气候变化而改变其海拔范围。重要的是，昆虫对温度变化敏感，并能快速响应，使它们成为监测气候变化影响的生物指示剂。但是，要监测山区气候变化的影响，重要的是要了解当地昆虫种群当前的海拔分布和其他生态特征。在这种情况下，我们建议一种识别甲虫类群的方法，该方法可用于监测热带山区昆虫物种对气候变化的影响。我们通过描述不同甲虫群体的海拔分布，并将这种分布与巴西东南部热带山区森林中物种的热范围相关联，来说明该方法。采样是在巴西RJ的Serra dosÓrgãos国家公园的大西洋雨林中进行的，大西洋雨林是全球主要的生物多样性热点之一。为了系统地采样不同海拔高度上的甲虫多样性，我们在雨季连续三个月在从130 m至2170 m asl的15个不同地点使用了飞行拦截“ Malaise”陷阱。为了调查物种的气候生态位，我们记录了这一时期的气候变量。我们收集了272个物种的2963个个体，属于六个鞘翅目群，温度梯度每升高100 m下降约0.5°C。考虑到热带山区物种的耐热性及其海拔范围和丰度较窄，认为属于天蛾科，Eu科（（科），兰科和ae科的五种鞘翅目物种是合适的生物指示剂，而mol科和兰科是海拔范围最窄的物种。 。我们建议使用海拔高度范围狭窄的丰富物种（或物种组）作为生物指示剂，对于监测气候变化对生物区系的影响可能是有价值的，从而使我们能够评估物种随时间变化的响应方式。考虑到热带山区物种的耐热性及其海拔范围和丰度较窄，认为属于天蛾科，Eu科（（科），兰科和ae科的五种鞘翅目物种是合适的生物指示剂，而mol科和兰科是海拔范围最窄的物种。 。我们建议使用海拔高度范围狭窄的丰富物种（或物种组）作为生物指示剂，对于监测气候变化对生物区系的影响可能是有价值的，从而使我们能够评估物种随时间变化的响应方式。考虑到热带山区物种的耐热性及其海拔范围和丰度较窄，认为属于天蛾科，Eu科（（科），兰科和ae科的五种鞘翅目物种是合适的生物指示剂，而mol科和兰科是海拔范围最窄的物种。 。我们建议使用海拔高度范围狭窄的丰富物种（或物种组）作为生物指示剂，对于监测气候变化对生物区系的影响可能是有价值的，从而使我们能够评估物种随时间变化的响应方式。Eu科和Lamp科是海拔范围最窄的科。我们建议使用海拔高度范围狭窄的丰富物种（或物种组）作为生物指示剂，对于监测气候变化对生物区系的影响可能是有价值的，从而使我们能够评估物种随时间变化的响应方式。Eu科和Lamp科是海拔范围最窄的科。我们建议使用海拔高度范围狭窄的丰富物种（或物种组）作为生物指示剂，对于监测气候变化对生物区系的影响可能是有价值的，从而使我们能够评估物种随时间变化的响应方式。
