Abstract

Strange oceanographic events such as El Niño and La Niña may have indirect effects on the local transmission processes of intestinal parasites due to the reduction or increase in populations of potential intermediate or definitive hosts. A total of 713 individuals of Lutjanus inermis (Peters) were collected over an 8-year period (October 2015 to July 2022) from Acapulco Bay, Mexico. Parasite communities in L. inermis were quantified and analysed to determine if they experienced interannual variations in species composition and structure as a result of local biotic and abiotic factors influenced by oceanographic events, such as El Niño-Southern Oscillation (ENSO), or La Niña, the cool phase of the ENSO climate pattern. Twenty-six taxa of metazoan parasites were recovered and identified: two Monogenea, eight Digenea, two Acanthocephala, four Nematoda, one Cestoda, seven Copepoda, and two Isopoda. Species richness at the component community level (8 to 17 species) was similar to reported richness in other species of Lutjanus Bloch. Parasite communities of L. inermis exhibited high inter-annual variation in the abundance of component species of parasite. However, the species richness and diversity were fairly stable over time. Climatic episodes of El Niño and La Niña probably generated notable changes in the structure of local food webs, thus indirectly influencing the transmission rates of intestinal parasite species. Changes in species composition and community structure of parasites possibly were due to variations in feeding behaviour during the events and differences in the host body size.

金鲷的寄生群落:在奇怪的气候事件中的年际变化。
奇怪的海洋事件,如El Niño和La Niña,由于潜在的中间或最终宿主种群的减少或增加,可能对肠道寄生虫的当地传播过程产生间接影响。2015年10月至2022年7月,在墨西哥阿卡普尔科湾共采集了713只美洲斑蝽(Lutjanus inermis, Peters)。本文对L. inermis的寄生虫群落进行了量化和分析,以确定它们的物种组成和结构是否受到海洋事件(如El Niño-Southern涛动(ENSO)或La Niña (ENSO气候模式的冷期)影响的本地生物和非生物因素的年际变化。共发现后生动物寄生虫26个分类,其中单目2个,棘头目8个,线虫目4个,足目1个,桡足目7个,等足目2个。组成群落水平上的物种丰富度(8 ~ 17种)与其他物种的丰富度相似。寄生蜂寄生群落的组成种丰度年际变化较大。然而,随着时间的推移,物种丰富度和多样性相当稳定。El Niño和La Niña的气候事件可能引起了当地食物网结构的显著变化,从而间接影响了肠道寄生虫物种的传播率。寄生虫种类组成和群落结构的变化可能与事件期间摄食行为的变化和寄主体型的差异有关。

期刊介绍: FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
