摘要

常见的非海洋介形虫Cypridopsis vidua（O.F.Müller，1776）被用作各种生物学学科的替代品，如（古）生态学、进化生物学、生态毒理学和寄生虫学。这种形态物种被认为是一种专性孤雌生殖。我们报道了在Woods Hole（MA，USA）发现的第一个具有雄性的C.vidua种群，并确定它是一个混合繁殖的种群。我们描述了雄性、有性和无性雌性的形态。我们展示了一只雄性和一只雌性的交配，以及一只雌性交配，表明雄性是有功能的。因此，维氏Cyridopsis vidua是一个混合繁殖的形态物种，而不是一个完全无融合生殖的孤雌生殖。我们首次使用多色偏振显微镜技术来说明介形虫的柔软部分。此外，我们还比较了两性种C.biseocleis、C.okeechobei、C.howei和C.schwartzi，并得出结论，这些物种，尤其是后三种，在形态上与C.vidua非常接近。

The common morphospecies Cypridopsis vidua (O.F. MÜLLER, 1776) (Crustacea, Ostracoda) is not an obligate parthenogen

The common non-marine ostracod Cypridopsis vidua (O.F. Müller, 1776) is used as a proxy in various biological disciplines, such as (palaeo-)ecology, evolutionary biology, ecotoxicology and parasitology. This morphospecies was considered to be an obligate parthenogen. We report on the discovery of the first population of C. vidua with males from Woods Hole (MA, USA) and determine that it is a population with mixed reproduction. We describe the morphology of the males and of the sexual and asexual females. We illustrate a copula of a male and a sexual female as well insemination in a sexual female, showing that males are functional. Therefore, Cypridopsis vidua is a morphospecies with mixed reproduction, not a full apomictic parthenogen. We use, for the first time, polychromatic polarization microscope technology to illustrate soft parts of ostracods. In addition, we compare the sexual species C. bisexualis, C. okeechobei, C. howei and C. schwartzi and conclude that these species, especially the latter three, are morphologically very close to C. vidua.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
