Abstract

Aim

A species' rate of climatic niche evolution may reflect its ability to survive changing climates. Yet large-scale studies of these rates remain limited. Here, we assessed global patterns in climatic niche rates among angiosperms and explored the potential drivers shaping these patterns.

Location

Global.

Time Period

Current.

Major Taxa Studied

Angiosperms.

Methods

We estimated broad-scale climatic niches for 231,567 angiosperm species based on distributional data from over 1100 sources. By integrating a published phylogeny of angiosperms, we estimated rates of climatic niche change for each extant species as the difference between its current and ancestral niche divided by the species' age. Global patterns were analysed by averaging rates for all the species found in each geographic unit. We used multiple statistical models to explore the relative contributions of niche width and climatic seasonality to shaping these geographic patterns of niche evolution. We analysed patterns of niche evolution and their underlying drivers separately for temperature-related and precipitation-related niches and for different directions of niche evolution (i.e., increases and decreases in species' temperature and precipitation niche values when compared to their most recent ancestors).

Results

Rates for temperature variables increased with latitude, whereas rates for precipitation variables decreased with latitude. These opposing patterns in temperature and precipitation rates were related to opposing latitudinal patterns in climatic seasonality and species' niche widths for temperature and precipitation. Rates also differed for different directions of niche evolution, with different patterns associated with changes to warmer vs. cooler climates and wetter vs. drier climates.

Main Conclusions

Our results revealed large-scale geographic patterns in rates of climatic niche change for temperature and precipitation for the largest clade of angiosperms and their underlying drivers. These findings may have important implications for species' abilities to respond to recent climate change.

被子植物气候生态位演化的全球格局

目的一个物种的气候生态位进化速度可以反映其在气候变化中生存的能力。然而，对这些比率的大规模研究仍然有限。在这里，我们评估了被子植物气候生态位率的全球模式，并探讨了形成这些模式的潜在驱动因素。位置全球。时间周期当前。被子植物的主要分类群。方法基于1100多个来源的分布数据，对231567种被子植物进行了大尺度气候生态位估算。通过整合已发表的被子植物系统发育，我们估计了每个现存物种的气候生态位变化率，即其当前和祖先生态位之间的差异除以物种的年龄。通过在每个地理单元中发现的所有物种的平均比率来分析全球模式。利用多种统计模型探讨了生态位宽度和气候季节性对生态位演化地理格局的相对贡献。我们分别分析了与温度相关的生态位和与降水相关的生态位的演化模式及其驱动因素，以及不同的生态位演化方向（即与它们最近的祖先相比，物种的温度和降水生态位值的增减）。结果温度变量率随纬度的增加而增加，而降水变量率随纬度的增加而减少。温度和降水速率的相反格局与气候季节性和物种生态位宽度的相反纬向格局有关。生态位进化的不同方向的速率也不同，气候变暖与变冷、气候变湿与变干燥的模式也不同。本研究揭示了被子植物最大支系温度和降水气候生态位变化速率的大尺度地理格局及其驱动因素。这些发现可能对物种应对近期气候变化的能力具有重要意义。

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.
