Molecular Phylogeny of North American Band-Winged Grasshoppers (Orthoptera: Acrididae)

A Molecular Biogeographic Analysis of the Relationship between North American Melanoploid Grasshoppers and Their Eurasian and South American Relatives

“…Base compositions are fairly uniform and approximately the same as those observed in other acridids (Chapco et al, 1997(Chapco et al, , 1999.…”

Body size-independent safety margins for gas exchange across grasshopper species

“…Therefore, we created a tree (animals identified by an asterisk in Table·1) from previously published works and from taxonomy. For relationships between family, subfamily and tribe, we used Otte and Nasrecki (Otte and Nasrecki, 1997), and for species relationships we used published molecular studies (Chapco et al, 1997;Chapco et al, 1999;Knowles and Otte, 2000). Then, we counted the number of branches at the level of family, subfamily, tribe, genus and species between each species pair as a measure of the distance between species (Fagan et al, 2002;Woods et al, 2004).…”

The phylogenetic placement of the rare North American band-winged grasshopper Shotwellia isleta Gurney, 1940 (Orthoptera: Acrididae: Oedipodinae)

“…Th e only molecular phylogenetic studies on North American band-winged grasshoppers to date (Chapco et al 1997 ;Fries et al 2007 ) examined only a few distantly related taxa, and did not include Shotwellia , but these analyses are not consistent with those of Otte ( 1984 ). Striking diff erences between phylogenetic hypotheses of these groups by Gurney ( 1940 ) and Otte ( 1984 ), along with a lack of comprehensive modern analysis of these groups, suggest a need for a modern cladistic analysis to better place Shotwellia and determine relationships between other members of the Chortophaga and Hippiscus and genus groups.…”

“…Chapco et al ( 1997 ) and Fries et al ( 2007 ) are the only studies, and those works include few genera and species. Th e most widely accepted current classifi cation of these grasshoppers is that by Otte ( 1984 ).…”
