This study sheds light on the complex relationship between land use, biodiversity, and the functional traits of dung beetles in Ecuador. The results indicate that the richness and abundance of dung beetles vary across different land uses and regions, with forests generally having a positive impact, while eucalyptus and pine plantations have a negative effect in certain areas. Specific indicator species, such as for forest areas and for eucalyptus plantations, were identified. This study also found that functional diversity analysis, based on morphological traits, revealed that certain traits, such as biomass, pronotum width, head width, and elytra length, were significant contributors to differences in dung beetle communities across various land uses and regions. This study highlights the potential conservation value of certain modified habitats and emphasizes the importance of considering both taxonomic and functional diversity when assessing the impact of land use on the ecosystem services provided by dung beetles. It underscores the potential value of plantations as refuges for dung beetle communities and the need for long-term assessments to better understand biodiversity changes over time.
这项研究揭示了厄瓜多尔土地利用、生物多样性与蜣螂功能特征之间的复杂关系。结果表明，蜣螂的丰富度和数量在不同土地利用类型和地区有所不同，森林通常具有积极影响，而桉树和松树种植园在某些地区具有负面影响。确定了特定的指示物种，如森林地区的 和桉树种植园的 。该研究还发现，基于形态特征的功能多样性分析表明，某些特征，如生物量、前胸宽度、头部宽度和鞘翅长度，是不同土地利用类型和地区蜣螂群落差异的重要促成因素。这项研究突出了某些改良栖息地的潜在保护价值，并强调在评估土地利用对蜣螂提供的生态系统服务的影响时，考虑分类多样性和功能多样性的重要性。它强调了种植园作为蜣螂群落避难所的潜在价值，以及进行长期评估以更好地了解生物多样性随时间变化的必要性。
