Abstract：
A total of 366 individuals of Lutjanus argentiventris (Peters, 1869) were collected over a 5-yr period (October 2018 to June 2022) from Acapulco Bay, Mexico. Parasite communities in Lutjanus argentiventris were quantified and analyzed to determine the main factors that generate changes in species richness and/or species composition over time. The digeneans and copepods were the best-represented parasite groups. The parasite communities were characterized by a high numerical dominance of ectoparasites, mainly isopod larvae. Species richness at the component community level (9-23 species) was similar to the reported richness in other Lutjanus spp. The parasite communities of Lutjanus argentiventris exhibited high variability in species composition, suggesting that each parasite species may respond differently to environmental changes. However, the species richness and diversity were fairly stable over time; therefore, a clear pattern of interannual variation was not observed. Variations in the community structure probably were due to factors such as host traits (e.g., feeding behavior and body size), and possible interannual differences in environmental factors amplified by the occurrence of the anomalous event of La Niña.
摘要：
Lutjanusargentiventris(Peters,1869)是从阿卡普尔科湾收集的，历时5年(2018年10月至2022年6月)，墨西哥。对Lutjanusargentiventris中的寄生虫群落进行了量化和分析，以确定随时间产生物种丰富度和/或物种组成变化的主要因素。二系和co足类是代表最好的寄生虫群体。寄生虫群落的特征是外寄生虫的数量优势很高，主要是等足幼虫。组分群落水平的物种丰富度（9-23种）与其他Lutjanusspp中报道的丰富度相似。Lutjanusargentiventris的寄生虫群落在物种组成上表现出很高的变异性，这表明每个寄生虫物种对环境变化的反应可能不同。然而,随着时间的推移，物种的丰富度和多样性相当稳定；因此，没有观察到年际变化的明显模式。群落结构的变化可能是由于宿主特征等因素(例如，喂养行为和体型)，以及拉尼娜异常事件的发生放大了环境因素的年际差异。
