摘要

非本地宠物交易物种的引入对全球生物多样性,特别是淡水生态系统构成潜在威胁。本研究调查了栖息在法国南部Fontcaude公园和附近Mosson河的野生樱桃虾种群(Neocaridina davidi)和共生的甲壳类种群(包括本地和非本地物种)的微孢子虫感染的季节动态。我们的目的是评估大叶藻和共生甲壳类动物之间潜在的溢出和/或溢出事件,以及季节动态对这些相互作用的影响。微孢子虫的流行率和多样性表现出强烈的季节变化。虽然没有检测到与宠物贸易相关的寄生虫,但我们强调了野生N. davidi获得的本地寄生虫,这似乎是本地寄主-一般小孢子虫的合适替代寄主。我们的研究结果表明,溢出事件发生的所有特权都得到满足。野生的N. davidi可以全年在欧洲的河流中建立和生存。因此,人类介导的引入可能会改变这些生态系统中寄生虫的传播动态。

Seasonal exchange of microsporidian parasites between native and non-native pet-traded freshwater crustaceans: Is parasite spillover favored over spillback?

The introduction of non-native pet-traded species poses potential threats to global biodiversity, particularly in freshwater ecosystems. This study investigated the seasonal dynamics of microsporidian infections in an established feral population of cherry shrimp (Neocaridina davidi) and the coexisting populations of crustaceans, comprising both native and non-native species, inhabiting the thermal waters of the Fontcaude Park and the nearby Mosson River in southern France. Our aim was to assess the potential occurrence of spillover and/or spillback events between N. davidi and co-occurring crustaceans, as well as the influence of seasonal dynamics on these interactions. The prevalence and diversity of microsporidian parasites exhibited strong seasonal variations. Although parasites associated with the pet trade were not detected, we highlight the acquisition of native parasites by feral N. davidi, which seems to be a suitable alternative host for native host-generalist microsporidians. Our findings indicate that all prerogatives for spillback events to occur are met. Feral N. davidi may establish and survive year-round in European rivers with natural thermal regimes. Thus, human-mediated introductions can potentially alter parasite transmission dynamics in these ecosystems.

期刊介绍: Parasite is an international open-access, peer-reviewed, online journal publishing high quality papers on all aspects of human and animal parasitology. Reviews, articles and short notes may be submitted. Fields include, but are not limited to: general, medical and veterinary parasitology; morphology, including ultrastructure; parasite systematics, including entomology, acarology, helminthology and protistology, and molecular analyses; molecular biology and biochemistry; immunology of parasitic diseases; host-parasite relationships; ecology and life history of parasites; epidemiology; therapeutics; new diagnostic tools. All papers in Parasite are published in English. Manuscripts should have a broad interest and must not have been published or submitted elsewhere. No limit is imposed on the length of manuscripts, but they should be concisely written. Papers of limited interest such as case reports, epidemiological studies in punctual areas, isolated new geographical records, and systematic descriptions of single species will generally not be accepted, but might be considered if the authors succeed in demonstrating their interest.
