Phylogenetic position of Antarctic scalpelliformes (Crustacea: Cirripedia: Thoracica)

first_imgThe phylogenetic relationships of seven Antarctic barnacle species, one verrucomorph and six scalpelliforms from the Scotia, Weddell and Ross seas were investigated using DNA sequences from two nuclear genes (18 S and 28 S) and one mitochondrial gene (COI), with a combined total length of 3,151 base pairs. Analyses of these new sequences, together with those of previously published ibliform, lepadiform, scalpelliform, balanomorph and verrucomorph species, confirm that the Scalpelliformes are not monophyletic. Bayesian and maximum likelihood analyses consistently recovered a monophyletic group which comprised Ornatoscalpellum stroemii (Sars) and the Southern Ocean scalpellomorphs; Arcoscalpellum sp. from the Weddell Sea, Arcoscalpellum africanum from Elephant Island, A. bouveti from Bouvet Island, the circum-Antarctic Litoscalpellum discoveryi, Litoscalpellum sp. from Shag Rocks and Scalpellum sp. from the Falkland Trough. We also used multiple fossil constraints in a relaxed clock Bayesian framework to estimate divergence times for the 18 S+28 S phylogeny. Our results indicate a mid Cretaceous divergence for the Weddell Sea Arcoscalpellum sp, followed by a late Cretaceous divergence from the North Atlantic O. stroemii. Subsequent to this, the Antarctic scalpellomorphs began to radiate at the Cretaceous-Tertiary boundary. Monophyly within the scalpellid genera Arcoscalpellum, Litoscalpellum and Scalpellum was strongly rejected by all loci. Our results show incongruence between taxonomy and molecular systematics and highlight the need for more species to be sequenced as well as taxonomic revisions to resolve uncertainties in the phylogenetic relationships of the stalked barnacles.last_img read more

More Sumner County Fair results: 2014 Pedal Tractor pull

first_imgSUMNER COUNTY FAIR 2014 PEDAL TRACTOR PULLSponsors – Home Lumber Company,  C & K Auto Parts,  P & K Equipment, York’s Garage, Prairieland Partners,  LuLu’s Café,  LX Ranch – Carson & Nina Ward,  Sumner County Fair Association…The Pedal Tractor Pull was held Sunday afternoon at 2 p.m. Aug 3, along the 200 block of South Chisholm following the Sand Pile Dig.  A group of parents, friends and family members gathered to watch and encourage 47 eager participants compete in nine age groups from 4 and Under to 12 years.  The top three finishers in each age group qualified to go on to compete at the Kansas State Fair in Hutchinson at the State Pedal Tractor Pull held in September.First, second, and third place trophies were presented in each age group with every participant receiving a coupon for a soft drink compliments of LuLu’s Café and a yellow ribbon from the Van DeCreek Pedal Tractor Pull of Abilene, Kansas.2014 pedal Tractor Pull Results:AGE 4 and Under ( 7 Entries) Tanner Clark Cooper Stanfield Camden WhiteOthers:  Paysley Lockhart,  Michael Gerstenkorn,  Gabe Oakley,  Denton WestAGE 5  (3 Entries)  Mak Fair,  Zak Eaton,  Keelen EatonAGE 6  (5 Entries) Tim Stevenson Ava Stanfield Anson CreedOthers:  Addi Skaggs,  Ashton MayAGE 7  (4 Entries) Cole VanZant Kooper Kelso Ashton MasonOthers:  Jaz NelsonAGE 8  (8 Entries) Shelby Popplewell Beckett May Jackson RisleyOthers:  Kasen Clark,  Hanna Lee,  Lexie Reilly, Phinnian BrideAGE 9  (7 Entries) Ben McRorie John Allen Furrh Christopher ClarkOthers:  Adrianna Creed,  Kelley Lowe,  Conner Dick,  Dylan DickAGE 10  (8 Entries) Carley Weir Jessie FurrhKaylee LambOthers:  Sam Eaton,  Brody Perkins,  Colby Barton,  Kaleb Oakley,  Lance BlubaughAGE 11  (4 Entries) Matthew Pryce Jody Furrh Phoebe RoopOthers:  Priscilla FoxAGE 12  (1 Entry) Trey CallowayFollow us on Twitter.
