      Determining the extent of natural hybridization and the ecological distribution of parental species and hybrids can contribute to our understanding of the role that ecology plays in reproductive isolation. The level of hybridization and differences in distribution between two closely related salmonid fishes, Arctic char (Salvelinus alpinus) and Dolly Varden (S. malma), were assessed across a wide variety of habitats in two southwestern Alaskan lakes. Our findings showed that Arctic char and Dolly Varden rarely hybridize and segregate across lake and stream habitats, suggesting that post-zygotic, environmentally-dependent selection against hybrids may be an important factor constraining gene flow in addition to differential use of spawning habitats.

      Sperm storage and spermatozoa interaction with epithelial cells in oviduct of Chinese soft-shelled turtle, Pelodiscus sinensis

      Spermatozoa can be stored within isthmus, uterine and vagina for a long time in the Chinese soft-shelled turtle after natural mating. The protection or/and nutrition of the oviduct epithelium, and the small population of immune cells in the genital tract would facilitate long-term sperm storage. In addition, Chinese soft-shelled turtle may be a potential model for uncovering the mechanism behind the sperm storage phenomenon.

      Hybridization in closely related Rhododendron species: half of all species-differentiating markers experience serious transmission ratio distortion

      Tobias Marczewski, David F. Chamberlain and Richard I. Milne

      Article first published online: 7 JUL 2015 | DOI: 10.1002/ece3.1570

      Thumbnail image of graphical abstract

      A pair of hybridising Rhododendron species was investigated with regards to differentiation at 146 AFLP loci. None of the loci showed fixed differences between the species, but over 45% of species differentiating markers showed significant transmission ratio distortion in early generation hybrids, indicating that they are affected by incompatibilities.

      Discrimination of grasshopper (Orthoptera: Acrididae) diet and niche overlap using next-generation sequencing of gut contents

      Beverly McClenaghan, Joel F. Gibson, Shadi Shokralla and Mehrdad Hajibabaei

      Article first published online: 7 JUL 2015 | DOI: 10.1002/ece3.1585

      Thumbnail image of graphical abstract

      Multiple specimens of four species of grasshopper were collected and diet analysis was performed using DNA metabarcoding of the gut contents. The rbcLa gene region was amplified and sequenced using Illumina MiSeq sequencing. Niche overlap values did not follow predicted patterns, however, the low values suggest low competition between these species.
