白蚁物种和功能群在全球各地区之间存在差异（功能多样性异常）。在这里，我们调查是否类似的差异，生物量和丰富的白蚁发生在大陆之间。在喀麦隆、马来西亚和秘鲁采用标准化抽样方法收集了生物量和丰度数据。来自秘鲁的数据是本研究的原始数据，而来自喀麦隆和马来西亚的数据是从其他来源汇编的。物种密度数据采用标准化样带（100 × 2 m）采样，而生物量和丰度测量采用基于2 × 2 m样方的标准化方案采样。生物量和丰度数据证实了物种密度的模式，从而证实了功能多样性异常的存在：喀麦隆的生物量和丰度估计最高（14.5 ± 7.90 g m−2和1234 ± 437 ind m−2）其次是马来西亚（0.719 ± 0.193 g m-2和327 ± 72 ind m-2），然后是秘鲁（0.345 ± 0.103 g m-2和130 ± 39 ind m-2）。对于大多数白蚁功能组，每个功能组的生物量和丰度在不同地点之间存在显着差异。谱系的生物地理分布是功能多样性异常的主要原因，真正的土壤喂养白蚁占主导地位，在喀麦隆和真菌生长的白蚁从秘鲁的情况下。这些发现很重要，因为生物量和功能群的丰度可能与生态系统进程有关。虽然这项研究允许来自不同地区的数据之间的比较，进一步的可比数据，以加强对白蚁在全球范围内的生态系统过程中的作用的理解。
Termite species and functional groups differ among regions globally (the functional-diversity anomaly). Here we investigate whether similar differences in biomass and abundance of termites occur among continents. Biomass and abundance data were collected with standardized sampling in Cameroon, Malaysia and Peru. Data from Peru were original to this study, while data from Cameroon and Malaysia were compiled from other sources. Species density data were sampled using a standardized belt transect (100 × 2 m) while the biomass and abundance measurements were sampled using a standardized protocol based on 2 × 2-m quadrats. Biomass and abundance data confirmed patterns found for species density and thus the existence of the functional diversity anomaly: highest estimates for biomass and abundance were found in Cameroon (14.5 ± 7.90 g m−2 and 1234 ± 437 ind m−2) followed by Malaysia (0.719 ± 0.193 g m−2 and 327 ± 72 ind m−2) and then Peru (0.345 ± 0.103 g m−2 and 130 ± 39 ind m−2). The biomass and abundance for each functional group were significantly different across sites for most termite functional groups. Biogeographical distribution of lineages was the primary cause for the functional diversity anomaly with true soil-feeding termites dominating in Cameroon and the absence of fungus-growing termites from Peru. These findings are important as the biomass and abundance of functional groups may be linked to ecosystem processes. Although this study allowed for comparisons between data from different regions further comparable data are needed to enhance the understanding of the role of termites in ecosystem processes on a global scale.
