Abstract
The distribution of Phalloceros species is generally allopatric and restricted; however, Phalloceros harpagos has a wide distribution and exhibits morphological variation among populations from different Brazilian river basins. Different species delimitation tests using cytochrome C oxidase subunit I gene sequences indicated that P. harpagos is a species complex that comprises between 7 and 9 phylogroups. The separation of the Paraná and Paraíba do Sul River basins most likely caused the diversification of these phylogroups in the Miocene period. The majority of phylogroups have a narrow distribution; however, one phylogroup has a broad distribution, being found primarily in the Paraná, Ribeira de Iguape, and Iguaçu River basins. This distribution can be attributed to possible headwater capture events caused by the reactivation of faults and erosion in the quaternary. Estimates about the times of divergence based on molecular data could be used to infer the biogeographic processes related to the diversification of South American freshwater fish.
Phalloceros物种的分布通常是异地的,并且受到限制;然而,哈氏Phalloceros分布广泛,在巴西不同流域的种群中表现出形态变异。利用细胞色素C氧化酶亚基I基因序列进行的不同物种划分试验表明。 harpagos是一个由7到9个门组组成的物种复合体。Paraná和Paraíba do Sul河流域的分离很可能导致了中新世时期这些门群的多样化。大多数门群分布狭窄;然而,有一个门群分布广泛,主要分布在Paraná、Ribeira de Iguape和Iguaçu河流域。这种分布可归因于第四纪断层复活和侵蚀可能引起的源头捕获事件。基于分子数据对分化时间的估计可用于推断与南美洲淡水鱼多样化相关的生物地理学过程。
期刊介绍:
Ecology of Freshwater Fish publishes original contributions on all aspects of fish ecology in freshwater environments, including lakes, reservoirs, rivers, and streams. Manuscripts involving ecologically-oriented studies of behavior, conservation, development, genetics, life history, physiology, and host-parasite interactions are welcomed. Studies involving population ecology and community ecology are also of interest, as are evolutionary approaches including studies of population biology, evolutionary ecology, behavioral ecology, and historical ecology. Papers addressing the life stages of anadromous and catadromous species in estuaries and inshore coastal zones are considered if they contribute to the general understanding of freshwater fish ecology. Theoretical and modeling studies are suitable if they generate testable hypotheses, as are those with implications for fisheries. Manuscripts presenting analyses of published data are considered if they produce novel conclusions or syntheses. The journal publishes articles, fresh perspectives, and reviews and, occasionally, the proceedings of conferences and symposia.
