Abstract

Aim

Species richness varies greatly over geographic gradients. Climate and other above-ground attributes are the most common variables used to explain animal richness patterns. However, soil properties may play an important role in shaping the richness of species living underground. Studies have yet to comprehensively analyse fossorial squamates' richness patterns and how soil properties influence them. We investigated how different predictors, including soil properties and climate, influenced the species richness of fully-fossorial, semi-fossorial, and non-fossorial squamates.

Location

Global.

Taxon

Reptilia: Squamata.

Methods

We categorised squamates into fully-fossorial, semi-fossorial, and non-fossorial, and assessed species richness for each category independently. We selected potential soil and climatic factors that could influence their richness. Then we used ordinary least squares regression models with spatially lagged variables (OLSL) and geographically weighted regression models with spatially lagged variables (GWRL) to investigate the influence of soil properties and climate on the species richness of each group.

Results

Fully-fossorial squamate richness peaks in Africa and South America. Semi-fossorial squamate richness is highest in South America and Australia. Non-fossorial squamates exhibit maximum species richness in South America and Southeast Asia. Species richness was more strongly associated with climate than soil properties in all groups. Nevertheless, as the levels of fossoriality increase, soil properties become more important correlates of species richness of squamates.

Main Conclusions

This study highlights the importance of incorporating soil factors alongside climate in the study of fossorial animal biogeography.

土壤性质对穴居类爬行动物物种丰富度的影响

目的物种丰富度在地理梯度上差异很大。气候和其他地上属性是用来解释动物丰富度模式的最常见变量。然而，土壤性质可能在塑造地下物种的丰富度方面发挥重要作用。研究还没有全面分析化石鳞片的丰富度模式以及土壤特性如何影响它们。我们研究了不同的预测因子，包括土壤性质和气候，如何影响全化石、半化石和非化石鳞片物种丰富度。位置全球。爬行纲分类群：有鳞目。方法将鳞片类分为全窝类、半窝类和非窝类，并对每一类的物种丰富度进行独立评估。我们选择了可能影响其丰富度的潜在土壤和气候因素。利用空间滞后的普通最小二乘回归模型（OLSL）和空间滞后的地理加权回归模型（GWRL）研究了土壤性质和气候对各类群物种丰富度的影响。结果全化石鳞类动物丰富度在非洲和南美洲最高。半穴居鳞片丰富度在南美洲和澳大利亚最高。非窝鳞类在南美洲和东南亚的物种丰富度最高。在所有类群中，物种丰富度与气候的相关性大于与土壤性质的相关性。然而，随着化石水平的提高，土壤性质成为鳞片物种丰富度的重要相关因素。本研究强调了土壤因子和气候因子在化石动物生物地理学研究中的重要性。
