Inferring Species Networks from Gene Trees in High-Polyploid North American and Hawaiian Violets (Viola, Violaceae)
The phylogenies of allopolyploids take the shape of networks and cannot be adequately represented as bifurcating trees. Especially for high polyploids (i.e., organisms with more than six sets of nuclear chromosomes), the signatures of gene homoeolog loss, deep coalescence, and polyploidy may become confounded, with the result that gene trees may be congruent with more than one species network. ...
متن کاملTraccatichthys tuberculum, a new species of nemacheiline loach from Guangdong Province, South China (Pisces: Balitoridae)
Traccatichthys tuberculum, new species, is herein described from the Jian-Jiang, a coastal river in Guangdong Province, South China. Photo by Bosco P.L. Chan. This new species differs from all other Chinese congeners (i.e., T. pulcher and T. zispi) in interorbital width, caudal-peduncle length, and pectoral-fin length. It, together with T. zispi, lacks the color patterns of the dorsal and anal ...
متن کاملA new species of the genus Rhabdophis Fitzinger, 1843 (Squamata: Colubridae) from Guangdong Province, southern China.
A new species, Rhabdophis guangdongensis sp. nov., is described from the Guangdong Province, China. It can be easily distinguished from other known congeners by cyt b and c-mos sequences, and by the following combination of morphological characters: body size small; head distinct from the neck; 20 maxillary teeth, the three most posterior teeth strongly enlarged, and not separated by diastemata...
متن کاملA new species of the genus Opisthotropis Gunther, 1872 (Squamata: Colubridae: Natricinae) from Guangdong Province, China.
A new natricid snake of the genus Opisthotropis Gunther, 1872, Opisthotropis laui sp. nov., is described from Mt. Gudou, Jiangmen City, Guangdong Province, China. The new species can be distinguished from other congeners by the combination of the following characters: dorsal scales weakly keeled throughout, in 25:23:23 rows; 10 supralabials; 11 infralabials; two internasals, longer than wide, n...
متن کاملViola kauaensis var. hosakae (Violaceae), a new variety of endemic Hawaiian violet
The Hawaiian endemic Viola kauaensis A. Gray has a broad distribution in bogs of Kaua`i and a limited distribution on mesic ridges in the Ko`olau Mountains of O`ahu. Based on differences in scale, the O`ahu populations of Viola kauaensis had previously been described as a distinct taxon. The taxonomic status of the O`ahu populations was reevaluated through a morphometric analysis of all varieti...
