The latitudinal diversity gradient (LDG) is a consequence of evolutionary and ecological mechanisms acting over long history, and thus is best investigated with organisms that have rich fossil records. However, combined neontological‐palaeontological investigations are mostly limited to large, shelled invertebrates, which keeps our mechanistic understanding of LDGs in its infancy. This paper aims to describe the modern meiobenthic ostracod LDG and to explore the possible controlling factors and the evolutionary mechanisms of this large‐scale biodiversity pattern.

海洋纬度多样性梯度，生态位保守性以及热带和北极以外地区：小型生物的气候敏感性

横向多样性梯度（LDG）是长期历史上进化和生态机制的结果，因此最好使用具有丰富化石记录的生物进行调查。但是，新的古生物学研究大多限于大型，带壳的无脊椎动物，这使我们对LDG的婴儿期保持了机械理解。本文旨在描述现代中底贝类兽类LDG，并探讨这种大规模生物多样性模式的可能控制因素和进化机制。
