Evolution and polyploid origins in North American Arctic Puccinellia (Poaceae) based on nuclear ribosomal spacer and chloroplast DNA sequences.
The proportion of polyploid plant species increases at higher latitudes, and it has been suggested that original postglacial Arctic immigrants of some large groups, including grasses, were polyploid. We analyzed noncoding nuclear and chloroplast DNA of all North American diploid Puccinellia (Poaceae) and a subset of arctic polyploids to hypothesize evolutionary relationships among diploids and ...
متن کاملPiptatherum ferganense (Poaceae), another Middle Asian species as a new record for the flora of Iran
Piptatherum ferganense is recorded as a new grass species for the flora of Iran collected from Ghorkhod Protected Area and Aladagh Mountains in North Khorassan province. The core distribution range of the species is Eastern Irano-Turanian with a disjunction in northeastern Iran. The morphological characters of P. ferganense are illustrated and compared with the closely related P. latifolium. I...
متن کاملArmillaria altimontana, a new species from the western interior of North America.
Armillaria altimontana, previously considered North American biological species (NABS) X, is described as new. To date, it appears that A. altimontana prefers higher-elevation, mesic sites within the dry, conifer forest zone of western interior North America. This species has been found on hardwoods and conifers and is associated most commonly with Abies-dominated forest types in southern Briti...
متن کاملChriolepis prolata, a new species of Atlantic goby (Teleostei: Gobiidae) from the North American continental shelf.
A new species of seven-spined goby of the genus Chriolepis is described from five specimens collected from the continental shelf of the northeastern Gulf of Mexico and Atlantic Ocean off South Carolina in depths of ca 54 to 110 m. The "Platform Goby", Chriolepis prolata, is distinguishable from all other western Atlantic species currently assigned to the genus Chriolepis and the morphologically...
متن کاملA new species of Axymyiidae (Diptera) from western North America and a key to the Nearctic species.
Adult, pupal and larval stages of the western Nearctic axymyiid, Protaxymyia thuja Fitzgerald and Wood n. sp., are described. The generic placement of this taxon is discussed in the context of the world axymyiid fauna and a key to differentiate all known life stages of Nearctic axymyiids is provided.
