摘要

遗存变形虫在系统发育上是一组非常多样化的真核微生物。它们可以在海洋和淡水栖息地以及土壤中找到。其中一些单细胞生物既栖息在地表也栖息在洞穴中,但它们在洞穴中的多样性几乎没有被探索过。最近在迪纳尔地区的研究表明,洞穴中的遗存变形虫表现出高度的多样性。本研究的目的是确定克罗地亚迪纳里克喀斯特地区利卡地区遗存变形虫的α多样性,并根据遗存变形虫的组合比较不同洞穴的栖息地。在8个洞穴中,我们发现了40多个遗嘱阿米巴类群,包括一个新的遗嘱阿米巴物种,Psammonobiotus dinaricasp。11 . Markov ponor(27个分类群)是最具多样性的遗存变形虫。bry - curtis相似指数表明,特有和濒危的孔洞双壳虫(Congeria jalzici, Markov ponor, Dankov ponor和Dražice ponor)所居住的洞穴中,没有孔洞双壳虫的洞穴中,有不同的变形虫组合。这种分化归因于下沉的利卡河的影响,它偶尔会完全淹没这些洞穴,为真核微生物创造特定的栖息地。这项研究有助于我们对洞穴中遗存变形虫的多样性、生物地理学和生态学的理解,并进一步了解C. jalzici种群的维持条件。

First data on testate amoebae associated with the endemic cave bivalve Congeria jalzici Morton & Bilandžija, 2013 with a description of Psammonobiotus dinarica sp. nov.
Testate amoebae are phylogenetically a very diverse group of eukaryotic microorganisms. They can be found in marine and freshwater habitats and in soil. Some of these single-celled organisms inhabit both surface and cave habitats, but their diversity in caves has barely been explored. Recent studies in the Dinaric region imply that testate amoebae in caves show a high diversity. The aim of this study was to identify the alpha diversity of testate amoebae in the Lika region (Dinaric karst, Croatia) and to compare the habitats of different caves based on testate amoebae assemblages. In eight caves we found more than 40 testate amoebae taxa, including a new testate amoeba species, Psammonobiotus dinaricasp. nov. The greatest diversity of testate amoebae was found in Markov ponor (27 taxa). The Bray-Curtis Similarity Index showed that testate amoebae assemblages in caves inhabited by the endemic and endangered cave bivalve Congeria jalzici (Markov ponor, Dankov ponor and Dražice ponor) differ from caves not inhabited by this species. This differentiation is attributed to the impact of the sinking Lika river, which occasionally completely submerges these caves, creating specific habitats for eukaryotic microorganisms. This study contributes to our understanding of the diversity, biogeography and ecology of testate amoebae in caves, as well as providing further insight into the conditions that sustain populations of C. jalzici.

期刊介绍: Subterranean Biology is an international journal published by Pensoft on behalf of the International Society for Subterranean Biology [SIBIOS-ISSB] for the publication of original and significant contributions on all aspects of subterranean life. The Journal will consider original scientific papers dealing with any aspect of subterranean ecosystems and their components focusing on biology, ecology, evolution and conservation. Reviews and Commentaries: The journal welcomes review articles on aspects of subterranean biology. They should be submitted in the same way as research articles but use a simple layout with no more than three levels of headings. Commentaries on previous matter published in the journal may be also considered. Both reviews and commentaries will be reviewed. Book Reviews: Reviews of books, symposia volumes and conferences pertinent to the journal are welcome. The journal publishes electronic versions of the articles when these are ready to publish, without delays that might be caused by completion of an issue. These electronic versions are not "pre-prints" but final and immutable (Version of Record), hence available for the purposes of biological nomenclature. The date indicated on the electronic version is to be considered the actual publication date.
