onion thrips, thrips tabaci lindeman, is a broadly distributed pest that attacks a wide range of crops. to investigate the intra-specific morphometric variation and the genetic diversity of the species in iran, four populations from tobacco plus 18 populations from onion were studied in some 17 provinces of iran. morphological analysis, using principal components and canonical discriminant anal...

geometric morphometric method was used to examine body shape variations among all the seven valid species of the genus alburnus in iran. in total 409 specimens of a. chalcoides, a. filippii, a. atropatenae, a. caeruleus, a. mossulensis, a. hohenackeri and a. zagrosensis were collected from babolrud, baleqlu-chai, miriseh, sarabeleh, gamasiyab, mahabad-chai rivers and the gandoman lagoon, respec...

landmark based geometric morphometrics and comparison of meristic characters was used to understand potential differences between populations of waspi in mashkil and mokran basins. 97 specimens of waspies were caught (64 from mashkil river and 33 from sarbaz river). 14 landmarks were digitized on pictures taken from left side of specimens and meristic characters were counted. data were analyzed...

Patterns of variation within the Montastraea "annularis" species complex: results from 2-D and 3-D geometric morphometrics. ii To the Gieszl, LaBella, and Cassara families iii ACKNOWLEDGMENTS

asian citrus psyllid, diaphorina citri kuwayama, is an important pest of citrus that transmits the bacterial pathogens responsible for citrus greening disease, also called huanglongbing. the aim of the current study was to investigate the shape variations of the forewing among the iranian geographic populations of d. citri, as well as one population from pakistan. the adult psyllids used in thi...

this study was conducted to evaluate the morphological responses of two different species including capoeta gracilis and alburnoides eichwaldii due to construction of the tarik dam in the sefidrud river using geometric morphometric technique. for this purpose, a total of 80 specimens of c. gracilis and 60 specimens of a. eichwaldii were collected from upstream and down-stream of dam. the left s...

it has been postulated that the building of the manjil and tarik dams on sefidroud river has led to the body shape variation of capoeta gracilis in up- and downstream populations due to the isolation. in this study, geometric morphometric approach was used to explore body shape variations of capoeta gracilis populations in up- and downstream manjil and tarik dams in sefidroud river from south o...

BACKGROUND & OBJECTIVES Insect wing morphology has been used in many studies to describe variations among species and populations using traditional morphometrics, and more recently geometric morphometrics. A landmark-based geometric morphometric analysis of the wings of three species of Aedes (Diptera: Culicidae), viz. Ae. aegypti, Ae. albopictus and Ae. pseudotaeniatus, at District Dehradun wa...
