Abstract

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 Homocopris buckleyi for forest areas and Onthophagus curvicornis 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.

桉树和松树种植园对厄瓜多尔南部地区蜣螂(鞘翅目:猩红甲虫)分类和功能多样性的影响。
这项研究揭示了厄瓜多尔土地利用、生物多样性和蜣螂功能特征之间的复杂关系。结果表明,蜣螂的丰富度和丰度在不同的土地用途和地区有所不同,森林一般具有积极影响,而桉树和松树种植园在某些地区则具有消极影响。研究确定了一些特定的指示物种,如森林地区的 Homocopris buckleyi 和桉树种植园的 Onthophagus curvicornis。这项研究还发现,基于形态特征的功能多样性分析表明,生物量、前胸宽度、头部宽度和背甲长度等某些特征是造成不同土地用途和地区蜣螂群落差异的重要因素。这项研究强调了某些改良栖息地的潜在保护价值,并强调了在评估土地利用对蜣螂提供的生态系统服务的影响时,同时考虑分类和功能多样性的重要性。它强调了种植园作为蜣螂群落庇护所的潜在价值,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。

期刊介绍: Biology (ISSN 2079-7737) is an international, peer-reviewed, quick-refereeing open access journal of Biological Science published by MDPI online. It publishes reviews, research papers and communications in all areas of biology and at the interface of related disciplines. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
