“…Our results also broadly mirrored those found by the recent meta-analysis of Bristol et al (2023) who focussed solely on nematodes and showed a non-significant increase in abundance as a result of precipitation increases and a non-significant decrease as a result of precipitation reductions. In addition, unlike the synthesis of Goncharov et al (2023) we found evidence for the impacts of precipitation change on mesofauna, while their study only found impacts of precipitation change on nematodes. In contrast to all previous similar meta-analyses on this topic (Blankinship et al, 2011;Goncharov et al, 2023;Peng et al, 2022), we found important evidence for nuanced effects of precipitation change.…”

Anthropogenic climate change is altering precipitation regimes at a global scale. While precipitation changes have been linked to changes in the abundance and diversity of soil and litter invertebrate fauna in forests, general trends have remained elusive due to mixed results from primary studies. We used a meta‐analysis based on 430 comparisons from 38 primary studies to address associated knowledge gaps, (i) quantifying impacts of precipitation change on forest soil and litter fauna abundance and diversity, (ii) exploring reasons for variation in impacts and (iii) examining biases affecting the realism and accuracy of experimental studies. Precipitation reductions led to a decrease of 39% in soil and litter fauna abundance, with a 35% increase in abundance under precipitation increases, while diversity impacts were smaller. A statistical model containing an interaction between body size and the magnitude of precipitation change showed that mesofauna (e.g. mites, collembola) responded most to changes in precipitation. Changes in taxonomic richness were related solely to the magnitude of precipitation change. Our results suggest that body size is related to the ability of a taxon to survive under drought conditions, or to benefit from high precipitation. We also found that most experiments manipulated precipitation in a way that aligns better with predicted extreme climatic events than with predicted average annual changes in precipitation and that the experimental plots used in experiments were likely too small to accurately capture changes for mobile taxa. The relationship between body size and response to precipitation found here has far‐reaching implications for our ability to predict future responses of soil biodiversity to climate change and will help to produce more realistic mechanistic soil models which aim to simulate the responses of soils to global change.

“…Climate change also affects the decomposition process hierarchically by shifting decomposer communities. For example, a recent meta-analysis reported by Goncharov et al (2023) showed a 1°C temperature rise results in a 12.5% increase in Acari but a 9.6% decrease in Collembola abundance. Figueroa et al (2021) found declines in invertebrate abundance with increasing temperature in cool temperate forests, while Zanne et al (2022) found that termite wood discovery rates increased with increasing temperature in the tropics.…”

“…The overall increase in forest litter decomposition mediated by invertebrates (31%) we estimated is similar in magnitude to that mediated by climate warming (14%-26%) predicted by Mori et al (2020). As there are a range of predictions that indicate changes in the diversity of decomposer organisms under climate change, we could see significant shifts in litter decomposition in the future; however, the direction and magnitude of this change remain unclear (Goncharov et al, 2023;Wall et al, 2010). Given the different responses of invertebrate taxa to a changing climate, understanding the roles of key decomposer invertebrate groups and their responses to climate change is essential for predicting future biogeochemistry.…”

“…Assessing the global distribution of the decomposer invertebrate taxa according to integrative disciplines to minimize methodological bias of empirical studies. For instance, combining molecular approaches like environmental DNA with traditional morphology will facilitate the collection of global data (Arribas et al, 2022;Geisen et al, 2019). Additionally, global collaboration networks will facilitate the management and sharing of these global data.…”

Forest litter decomposition is an essential component of global carbon and nutrient turnover. Invertebrates play important roles in litter decomposition, but the regional pattern of their effects is poorly understood. We examined 476 case studies across 93 sites and performed a meta‐analysis to estimate regional effects of invertebrates on forest litter decomposition. We then assessed how invertebrate diversity, climate and soil pH drive regional variations in invertebrate‐mediated decomposition. We found that (1) invertebrate contributions to litter decomposition are 1.4 times higher in tropical and subtropical forests than in forests elsewhere, with an overall contribution of 31% to global forest litter decomposition; and (2) termite diversity, together with warm, humid and acidic environments in the tropics and subtropics are positively associated with forest litter decomposition by invertebrates. Our results demonstrate the significant difference in invertebrate effects on mediating forest litter decomposition among regions. We demonstrate, also, the significance of termites in driving litter mass loss in the tropics and subtropics. These results are particularly pertinent in the tropics and subtropics where climate change and human disturbance threaten invertebrate biodiversity and the ecosystem services it provides.
