Habitat specificity Spumella like flagellates

项目摘要

Heterotrophic heterokonts, and specifically Spumella-like chrysomonads, are among the most abundant planktonic protists and among the most important grazers of bacteria-sized microorganisms. Even though protist diversity is tremendous, taxonomy has typically been coarse and flexible. Further, due to the historic classification of microorganisms in either animals or plants the taxonomic notation even at higher taxonomic levels is not consistent, i.e., the botanical (Chrysophyceae) and zoological (Chrysomonadida) nomenclature differs. As Spumella (=Monas) is one of the first ever described protist taxa a revision specifically of this taxon has broad implications for systematics of eukaryotiv microorganisms in general. Adressing this issue, however, requires a concerted interdiciplinary effort which will be adressed in 4 working packages. We will analyse the habitat specificity of different lineages and analyse species discrimination based on morphological, molecular and experimental data. Based on these data we will describe approximately 20 new species and approximately 5 new genera of flagellates affiliated with the Spumella morphodeme as a basis for a revision of colourless flagellates affiliated with the chrysophycean C-cluster.

异养异鞭毛类，特别是泡沫状金单胞菌，是最丰富的浮游原生生物之一，也是细菌大小的微生物的最重要的食草动物之一。尽管原生生物的多样性是巨大的，分类通常是粗糙和灵活的。此外，由于动物或植物中微生物的历史分类，即使在更高的分类水平上，分类符号也不一致，即，植物学（绿藻纲）和动物学（绿藻纲）的命名法不同。由于泡沫菌属（=单胞菌属）是最早描述的原生生物分类群之一，因此对该分类群的修订对真核微生物的系统学有着广泛的意义。然而，解决这一问题需要协调一致的跨部门努力，将在4个工作包中加以解决。我们将分析不同谱系的栖息地特异性，并根据形态学，分子和实验数据分析物种歧视。基于这些数据，我们将描述约20个新种和约5个新属的鞭毛隶属于Spumella morphodeme作为基础的修订无色鞭毛隶属于金藻C-集群。
