The wood economics spectrum modulates the positive effects of termite foraging intensity on deadwood invertebrate diversity

How populations of ecosystem engineers are both driven by and drive biodiversity is poorly known, even less so in detrital subsystems. Deadwood plays a key role in maintaining biodiversity and ecosystem functions. Wood economics spectrum (WES), which represents the initial wood quality through a cluster of wood traits, via afterlife effects might affect termite populations and deadwood invertebrate community structure. Termites, as ecosystem engineers, exert a significant impact on other invertebrate diversity. However, how the WES modulates the effects of termite foraging intensity on deadwood invertebrates is unclear. We hypothesized that the WES had significant effects on termite foraging intensity and deadwood invertebrate abundance and richness. Moreover, the WES was hypothesized to modulate the effects of termite foraging intensity on deadwood invertebrate diversity. We conducted a wood decomposition experiment to test our hypotheses in two subtropical forests in China. Logs ..., Data collected
Invertebrate sampling, identification and counting: In July 2020, 147 logs (22 species) of 35 cm length were quickly and carefully put into plastic zip-lock bags in filed and taken into the laboratory at Tiantong and Putuo Ecological Station, where the samples were stored at 15 °C for subsequent processing. First, we put the wood sample in a deep plastic tray and collected larger, visibly active invertebrates by hands to prevent escape before processing. Then, we sawed the log into two halves, and then we sawed a 2.5 cm thick disk at each end of each half log. This way, we collected two disks from the middle and end positions. We used one middle disk and one ends disk to measure termite foraging intensity, and the other half for mass loss and traits analysis (not included in this study). The remaining logs (25-cm long) were used to analyze the composition and diversity of the other wood-inhabiting invertebrate community.

Ci et al. (2025), Data from: **The wood economics spectrum modulates the positive effects of termite foraging intensity on deadwood invertebrate diversity**

The dataset includes the measured data of wood economic spectrums (PC1) based on the wood carbon, nitrogen, and phosphorus content, lignin, cellulose content, and wood density and relative termite feeding area and termite imported soil mass per volume. As well as invertebrate abundance (excluding termites and ants) invertebrate richness and the abundance of other important detritivores and ants.

生态系统工程物的种群如何既受生物多样性驱动、又反过来推动生物多样性，这一问题迄今仍不甚明确，而在碎屑子系统中对此的认知则更为匮乏。枯木在维持生物多样性与生态系统功能方面发挥着关键作用。木材经济学谱（Wood Economics Spectrum, WES）通过一系列木材性状表征初始木材品质，其通过枯木腐烂后的遗留效应，可能会影响白蚁种群以及枯木无脊椎动物群落结构。作为生态系统工程物的白蚁，对其他无脊椎动物的多样性具有显著影响。然而，木材经济学谱如何调控白蚁觅食强度对枯木无脊椎动物的影响，目前仍不明确。本研究提出两项假设：其一，木材经济学谱对白蚁觅食强度以及枯木无脊椎动物的多度与物种丰富度具有显著影响；其二，木材经济学谱可调控白蚁觅食强度对枯木无脊椎动物多样性的作用效果。
本研究在中国的两处亚热带森林中开展木材分解实验以验证上述假设。枯木……

# 样本采集
无脊椎动物采样、鉴定与计数：2020年7月，研究人员将147段长度为35 cm的枯木（隶属于22个物种）在野外快速且小心地装入塑料自封袋中，带回至天童与普陀生态站实验室，样品暂存于15 ℃环境中以待后续处理。首先，将木材样品置于深塑料托盘内，手工采集体型较大、肉眼可见的活动无脊椎动物以避免其逃逸。随后将整段枯木锯为两半，并在每半段枯木的两端各锯取一块厚度为2.5 cm的圆盘，由此从中部与端部位置各获得两块圆盘。研究人员使用一块中部圆盘与一块端部圆盘测定白蚁觅食强度，剩余半段枯木用于质量损失与性状分析（本研究未包含该部分内容）。余下长度为25 cm的枯木片段则用于分析其他枯木栖息无脊椎动物群落的组成与多样性。
