Abstract

We evaluated short- (among months within-years) and long-term (between 1999-2000 and 2016-2017) temporal patterns of taxonomic and functional β- diversity (and its components of substitution and gain/loss) of dung beetle assemblages in forest fragments and pastures in the Los Tuxtlas Biosphere Reserve (LTBR). Habitat type affected the taxonomic dissimilarity and the richness difference component, with average values being respectively 1.42 and 1.56 times higher in pastures than in forest fragments. Only habitat type was important for functional richness, being 1.93 and 1.69 higher in forest fragments than pastures in 1999-2000 and 2016-2017, respectively. Pastures were taxonomically and functionally poorer but were also more temporally dynamic than forest fragments both within-year and between-years. Habitat type is a determining factor for temporal dynamics, with forest fragments presenting more stable dung beetle assemblages than cattle pastures.

墨西哥Los Tuxtlas生物圈保护区森林碎片和牧场中屎壳郎分类和功能多样性的时间变化

本研究对洛斯·塔克斯特拉斯生物圈保护区(LTBR)森林碎片和牧场中屎壳郎群落分类和功能β-多样性(及其替代和损益成分)的短期(年/月)和长期(1999-2000年和2016-2017年)时间格局进行了评价。生境类型对分类差异和丰富度差异分量有影响，牧场的平均值分别是森林破碎片的1.42倍和1.56倍。只有生境类型对功能丰富度有重要影响，1999-2000年和2016-2017年，森林破碎片的功能丰富度分别比牧场高1.93和1.69。牧草在分类学和功能上较差，但在年内和年间的时间动态也比森林碎片更强。生境类型是时间动态的决定因素，森林碎片比牛牧场呈现更稳定的屎壳郎组合。
