概括

在日本的河系统中发现了一种引入的三动物,Dollfustrema invadens. 这种寄生虫感染金和淡水鱼,影响水生生态系统.

科学领域:

寄生虫学的寄生虫学
分子生物学分子生物学
生态生态学生态生态学

背景情况:

金 (Limnoperna fortunei) 和淡水鱼是托恩河生态系统的关键组成部分.
引入的物种可以破坏本地水生环境及其食物网.

研究的目的:

为了识别和描述在河系统中发现的三毛动物.
为了阐明引入的三毛动物的生命周期和宿主-寄生虫相互作用.
评估贝和鱼类中形虫感染的流行率.

主要方法:

在Tone河系统的28个地点 (2021-2023) 实地采样贝和鱼类.
使用28S rDNA和ITS1-5.8S-ITS2区域进行物种识别的分子分析.
对寄生虫标本进行形态检查.

主要成果:

形虫"Dollfustrema hefeiense"被确定为一种引入的物种,并重新描述为Dollfustigma invadens n. sp.
在金和鱼肌中分别发现了囊和囊细胞.
在道鱼 (Ictalurus punctatus) 和鱼的肌肉中发现了成年三角形鱼,这表明直接发育.
另一个引入的三角动物,Prosorhynchoides ozakii,也被检测到,并观察到共感染.

结论:

Dollfustrema invadens是日本最近描述的一种入侵性三动物,其复杂的生命周期涉及和鱼.
D. invadens和P. ozakii的存在凸显了生物入侵对Tone河生态系统的影响.
需要进一步的研究来了解这些引入的生态后果.

关键词:

娃娃公司的高效感受.杜尔夫斯特雷马 (Dollfustrema invadensens) 是一个入侵性的动物.普罗索林霍伊德斯 (Prosorhynchoides ozakii) 已经成为一个常见的疾病.生命周期生命周期一个名字叫做Nomen nudum.

Diversity of Protists III

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Diversity of Protists IV

Diversity of Protists IV

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...
