Abstract

Aim

Tropical niche conservatism (TNC) and dispersal limitation (DL) are major ecological and evolutionary mechanisms in shaping taxonomic and phylogenetic β-diversities. While these mechanisms have been studied in plants and vertebrates, their roles in freshwater taxa remain unclear. We leveraged Odonata species distribution and phylogenetic data to map geographical patterns of taxonomic and phylogenetic β-diversities, and to determine whether Odonata β-diversity is primarily shaped by TNC or DL and whether temperature seasonality is a key driver determining TNC.

Location

Eastern China.

Time Period

Present.

Major Taxa Studied

Odonata.

Methods

A moving window containing nine grids of 50 × 50 km was employed to quantify taxonomic and phylogenetic β-diversities, including their turnover and nestedness components. A null model was utilised to calculate randomly expected phylogenetic β-diversity based on observed taxonomic β-diversity and site-specific regional species pools. The generalised dissimilarity model was used to assess the roles of climatic and geographic distances shaping β-diversity and to identify the key climatic factors.

Results

Taxonomic total β-diversity and its turnover component were generally higher than phylogenetic β-diversity in most Odonata communities, with phylogenetic β-diversity being relatively higher mainly in tropical regions. Current climatic factors independently explained slightly more of the variation in total β-diversity than geographic distance alone, while geographic distance independently explained slightly greater proportions of deviance in turnover components. However, their joint effects accounted for an even larger part of the variation in β-diversity. The key climatic predictors were temperature seasonality.

Main Conclusions

Current climatic factors, particularly temperature seasonality, largely shape taxonomic and phylogenetic β-diversities of Odonata communities. Spatial turnover along the climatic gradient tends to involve phylogenetically related taxa, resulting in overall higher taxonomic than phylogenetic β-diversity, supporting the TNC. The joint effects of climatic and geographic distances highlight the roles of climate, interacting with topographic complexity, shaping taxonomic and phylogenetic β-diversities of Odonata in eastern China.

热带生态位保守性和扩散限制共同决定了中国东部蜥目动物的分类和系统发育多样性
目的热带生态位保守性(TNC)和扩散限制(DL)是形成β-植物分类和系统发育多样性的主要生态和进化机制。虽然这些机制已经在植物和脊椎动物中得到了研究,但它们在淡水分类群中的作用仍不清楚。我们利用齿蛙的物种分布和系统发育数据来绘制齿蛙的分类和系统发育β-多样性的地理格局,并确定齿蛙β-多样性主要是由TNC还是DL形成的,以及温度季节性是否是决定TNC的关键驱动因素。地点:中国东部。时间:现在。主要分类群研究蜥目动物。方法采用一个包含9个50 × 50 km栅格的移动窗口,量化其分类和系统发育β-多样性,包括它们的周转和巢性成分。基于观察到的分类β-多样性和特定地点的区域物种库,采用零模型计算随机期望系统发育β-多样性。采用广义差异模型评估气候和地理距离对β-多样性的影响,并确定关键气候因子。结果大部分齿蛙动物群落的总β多样性及其周转成分普遍高于系统发生β多样性,系统发生β多样性主要在热带地区相对较高。当前气候因子对总β多样性的独立解释略高于地理距离,而地理距离对周转成分偏差的独立解释略高于地理距离。然而,它们的共同作用在β多样性的变化中占了更大的一部分。关键的气候预测因子是温度季节性。主要结论当前气候因素,特别是温度季节性,在很大程度上决定了齿蛙群落的分类和系统发育多样性。沿着气候梯度的空间转换倾向于涉及系统发育相关的类群,导致总体上分类多样性高于系统发育多样性,支持TNC。气候和地理距离的共同作用突出了气候的作用,与地形复杂性相互作用,形成了中国东部齿蛙类的分类和系统发育多样性。

期刊介绍: Global Ecology and Biogeography (GEB) welcomes papers that investigate broad-scale (in space, time and/or taxonomy), general patterns in the organization of ecological systems and assemblages, and the processes that underlie them. In particular, GEB welcomes studies that use macroecological methods, comparative analyses, meta-analyses, reviews, spatial analyses and modelling to arrive at general, conceptual conclusions. Studies in GEB need not be global in spatial extent, but the conclusions and implications of the study must be relevant to ecologists and biogeographers globally, rather than being limited to local areas, or specific taxa. Similarly, GEB is not limited to spatial studies; we are equally interested in the general patterns of nature through time, among taxa (e.g., body sizes, dispersal abilities), through the course of evolution, etc. Further, GEB welcomes papers that investigate general impacts of human activities on ecological systems in accordance with the above criteria.
