A total of 365 fish were collected seasonally from the San Juan River (Argentina) between 2022 and 2025. Infection was highly prevalent (89.0%), and parasite abundance showed a strongly aggregated distribution that was analysed using generalized linear models with a negative binomial distribution. Host total length was the main predictor of parasite abundance, supporting a pattern of size-dependent accumulation. A significant interaction between length and sex indicated that parasite abundance increased with body size and was higher in females than in males, particularly among larger individuals, whereas smaller fish exhibited low parasite abundance. Seasonality had a limited effect, with parasite abundance being approximately 24% lower in autumn than in winter (p = 0.041), while no significant differences were detected among the remaining seasons. These findings suggest that cumulative infection processes may obscure short-term seasonal variation in transmission. In this arid river system, parasite abundance appeared to be more strongly associated with host characteristics, particularly body size and sex, than with seasonal variation.

Xiphophorus hellerii (Green swordtail), an ornamental fish popular in the aquarium trade, has established populations worldwide, yet the mechanisms underlying their spread remain unclear. Using nuclear single nucleotide polymorphisms (SNPs) from the X. hellerii native range in Mexico and Central America and the introduced range in the continental United States and Hawaii, we tested the hypothesis that introduced X. hellerii are hybrids with two widely introduced congeners, X. maculatus and X. variatus. To determine whether a single introduction occurred or multiple introductions from different sources, we investigated the geographic sources of introduced X. hellerii. We found no evidence of hybridization with congeners, indicating that hybridization has not significantly contributed to invasion success. We suggest that the source of introduced X. hellerii includes multiple admixed populations from the center of the native range in Mexico, rather than from peripheral populations. Introduced populations form a monophyletic clade, consistent with establishment from a limited number of founders, followed by isolation and genetic drift that homogenized genotypes. Within the native range, peripheral populations show restricted gene flow, while central basins exhibit greater connectivity, consistent with dendritic river systems where mainstem connections and Pleistocene drainage changes enhance genetic exchange. These findings highlight the roles of founder effects and demographic history in facilitating invasion. Resolving these processes is essential for guiding management strategies, predicting potential range expansions, and informing future studies on the colonization of novel environments.\u0000 </div>","PeriodicalId":11422,"journal":{"name":"Ecology of Freshwater Fish","volume":"35 4","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148616036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is particularly evident for trophically transmitted parasites, such as Dibothriocephalus tapeworms, which infect multiple intermediate fish hosts, potentially reducing their fitness and suitability for human consumption. Here, we used a large, multi-year dataset to examine ecological underpinnings between Dibothriocephalus burden and host traits and diet. In particular, we assessed relationships between parasite burden and body size, body condition, growth, restocking origin and stomach contents in the key piscivorous salmonids, Arctic charr (Salvelinus alpinus) and brown trout (Salmo trutta), in a large subarctic lake, Lake Inari. We found that Dibothriocephalus prevalence was similarly high in both salmonids, with decreasing parasite burden over the years. In both species, larger individuals and those having three-spined (Gasterosteus aculeatus) and/or ninespine (Pungitius pungitius) stickleback remnants in their stomachs had a higher parasite burden, whereas better body condition, quicker growth, stomach contents other than sticklebacks, stocked origin (in Arctic charr) and river habitat (in brown trout) were associated with lower parasite counts. These findings suggest that Dibothriocephalus burden is likely to be costly, while successful foraging on non-stickleback food is associated with lower burden. Overall, the results highlight the intricacy of trophic accumulation of Dibothriocephalus parasites, with sticklebacks playing a special role in their transmission.","PeriodicalId":11422,"journal":{"name":"Ecology of Freshwater Fish","volume":"35 4","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eff.70055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148358159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
