Data from Queiroz et al 2022 Biotropica Ant diversity decreases during the dry season: a meta-analysis of the effects of seasonality on ant richness and abundance Abstract Tropical studies traditionally describe insect diversity variation throughout the year. The temporally structured responses of insect assemblages to climate seasonality vary across ecosystems due to gradients of resource availability and limiting ecological factors. These idiosyncratic responses might be particularly true across the vast geographical range of the Brazilian territory, including various environments that harbor one of the most diverse ant faunas worldwide. This study addressed the relationship between ant diversity and climatic seasonality, performing a quantitative review of the published data on ant diversity collected in Brazil. We investigated the seasonality effect on ant abundance and richness described in the literature in 47 papers published between 2000 and 2018. These studies were developed mainly in the Atlantic Forest biome and collected ants with pitfall traps on the soil/litter stratum. We initially carried out a vote-counting procedure by comparing the number of significant results describing seasonal differences in the ant assemblage. We found that most papers described a similar pattern of ant abundance, richness, and species composition between seasons. However, when we performed a meta-analysis, we observed a clear pattern of higher ant abundance and richness in the wet/summer season compared with the dry/winter season. Our meta-analysis reveals that the ant diversity decreases in the dry season, strongly in the Cerrado biome. Additionally, we point out differences in the sampling effort across biomes, indicating the need for further investments in studies focused on temporal diversity patterns, including seasonal effects, on the insect assemblage in biomes less investigated so far.

《旱季蚂蚁多样性下降：季节波动对蚂蚁物种丰富度与多度影响的元分析》
摘要：传统热带生态学研究通常会阐释昆虫多样性的年度动态变化。昆虫群落对气候季节波动的时间结构化响应，会因资源可获得性梯度与限制性生态因子的差异，在不同生态系统中呈现显著分异。在地域广袤的巴西境内，这种独特的响应模式或许尤为突出——巴西拥有全球物种最为丰富的蚂蚁区系之一，且涵盖了多样的生境类型。本研究聚焦蚂蚁多样性与气候季节波动之间的关联，对巴西境内已发表的蚂蚁多样性调查数据开展定量综述。我们梳理了2000年至2018年间发表的47篇文献中，关于季节波动对蚂蚁多度与物种丰富度影响的研究结果。这些研究主要在大西洋森林生物群区开展，采用陷阱法（pitfall traps）采集土壤/枯落物层的蚂蚁样本。我们首先采用投票计数法，对比了描述蚂蚁群落季节差异的显著研究结果的占比。研究发现，多数文献均指出蚂蚁多度、物种丰富度及物种组成在不同季节间无显著差异。然而，在开展元分析（meta-analysis）后，我们却观察到清晰的规律：相较于旱季/冬季，湿季/夏季的蚂蚁多度与物种丰富度显著更高。本次元分析结果表明，旱季蚂蚁多样性会出现下降，且这一现象在塞拉多（Cerrado）生物群区尤为显著。此外，我们还发现不同生物群区的采样投入存在显著差异，这表明针对当前研究程度较低的生物群区，开展昆虫群落时间多样性动态（包括季节波动效应）相关研究的必要性亟待强化。
