摘要

根据物种-时间关系(STR),物种多样性会随着样本时间粒度的增加而增加,从而影响古生态学分析,因为化石组合的时间粒度(时间平均)相差几个数量级。我们预测化石群的总丰度与样本大小无关的多样性(ADR)之间存在正相关关系,因为沉积物累积量减少决定了时间平均值的增加,而时间平均值的增加应该会增加丰度并抑制物种的优势地位。我们证明,与非平均生物群落的负 ADR 不同,全新世化石群落的 ADR 是正的,无论是无条件的还是以能量可用性梯度为条件的。然而,当以沉积物堆积为条件时,化石的正ADR就消失了,这表明ADR是可变时间平均所引起的多样性缩放的特征。以沉积物累积为条件的 ADR 可以识别并消除时间平均化引起的缩放效应,从而为跨时空的生物多样性比较提供一个无偏见的途径。

Abundance–diversity relationship as a unique signature of temporal scaling in the fossil record

Species diversity increases with the temporal grain of samples according to the species–time relationship (STR), impacting palaeoecological analyses because the temporal grain (time averaging) of fossil assemblages varies by several orders of magnitude. We predict a positive relation between total abundance and sample size-independent diversity (ADR) in fossil assemblages because an increase in time averaging, determined by a decreasing sediment accumulation, should increase abundance and depress species dominance. We demonstrate that, in contrast to negative ADR of non-averaged living assemblages, the ADR of Holocene fossil assemblages is positive, unconditionally or when conditioned on the energy availability gradient. However, the positive fossil ADR disappears when conditioned on sediment accumulation, demonstrating that ADR is a signature of diversity scaling induced by variable time averaging. Conditioning ADR on sediment accumulation can identify and remove the scaling effect caused by time averaging, providing an avenue for unbiased biodiversity comparisons across space and time.

期刊介绍: Ecology Letters serves as a platform for the rapid publication of innovative research in ecology. It considers manuscripts across all taxa, biomes, and geographic regions, prioritizing papers that investigate clearly stated hypotheses. The journal publishes concise papers of high originality and general interest, contributing to new developments in ecology. Purely descriptive papers and those that only confirm or extend previous results are discouraged.
