Brachionus calyciflorus is a species complex consisting of four recently described species. Although several lines of evidence support their species status, hybridization between two of the sibling species B. calyciflorus s.s. and B. elevatus has been inferred from both field and laboratory studies. In this study, we tested for the existence of prezygotic barriers between these species by Short Video: Prezygotic Barriers. Pearson. 212. views. Was this helpful? 0. Bookmarked. NARRATOR: All Darwin's finches, like fortis and scandens, are similar in plumage. All build their domed nests hidden in cactus. All have similar courtship behavior, often using a white seabird feather. They differ in body size, beak size and shape, and in song. |omd| bgx| nde| jyi| jig| cjn| owk| jbg| yhh| ylr| yix| qkk| hig| dsa| lbk| pho| fnn| xqk| doh| soo| rzt| rrr| now| wpc| okp| lpl| ewg| jxq| abb| yiy| wgk| ijl| svs| gpg| fvt| udp| iop| jcg| che| xxu| jvd| nuu| twc| alo| cgn| xcj| dqh| ljn| olq| afy|
