The present study was carried out in Agricultural Research Station, Hagari during rabi 2020, it undertaken to assess nature of genetic variability and diversity among 200 mutant lines M4 generation. revealed wide variation for yield attributing traits, moderate GCV PCV coupled with high heritability advance observed stem girth, panicle length width. traits viz., length, weight, width, 100-seed ...

Thirteen morphometric characters were compared between two cryptic species of gray treefrogs from Ohio. Discriminant function analysis using snout-vent length, shank length, and thigh length correctly classified 76.7% of diploid Hyla chrysoscelis and tetraploid//. versicolor. Ohio diploids are more similar in size to those in Texas than to those of Michigan and Wisconsin or southeastern states....

in this study, 52 specimens of adult indian gerbil (tatera indica) were collected by live traps (sherman traps, havahart traps and locally made traps) from range of different habitats of two localities, geno protected area (or geno biosphere reserve) and minab county, hormozgan province. at first, external, cranial and dental characters were measured and then the ratio of measured characters to...

Distribution, population and reproductive biology of Uca sindensis were studied in a subtropical mangrove of Pohl port in the northern Persian Gulf. Sex ratio, distribution, population structure, handedness (evenness), diameter burrow, breeding season and fecundity were investigated. Ten 0.5 m2 quadrates were randomly sampled during low tide periods from October 2009 to September 2010.A total o...

Hierarchical cluster analysis based on female morphometric character means including body length, distance from vulva opening to anterior end, head width, odontostyle length, esophagus length, body width, tail length, and tail width were used to examine the morphometric relationships and create dendrograms for (i) 62 populations belonging to 9 Longidorus species from Arkansas, (ii) 137 publishe...

evaluation of morphological variations in 70 genotypes of seven accessions of thymus caramanicus jalas.growing in central iran was carried out, for determining valuable characters for future breeding programs and medicinal purposes. in this study 30 quantitative and qualitative characters were evaluated. the results revealed great variabilities of important traits among populations. results of ...

The biology of the Ucides cordatus in Vitória Bay (ES) was evaluated as a possible tool for population management. Sampling occurred monthly for about a year (October 1998 to September 1999) with biometric analysis (CW = carapace width; WW = total wet weight) and abiotic factors on four transects, each with four bands (margin to supratidal region). The density was 3.7±1.5 crabs.m, with an incre...

—Two new species of freshwater crabs of the genus Ptychophallus Smalley, from Panama, P. uncinatus and P. kuna, are described and illustrated. The addition of these two species means the genus now includes 13 species, all of which are distributed in Panamd and Costa Rica. The species are distinguished primarily by differences in characters of the male first gonopod. A sunmiary of the geographic...

This study investigated the effect of the installation of flood dams on the morphological variation of Alburnoides samiii Mousavi-Sabet, Vatandoust & Doadrio, 2015, in Toolkhone River, origin from Somam Mountain, the South Caspian Sea basin, north of Iran. Multivariate analysis (MANOVA) was employed for morphometric characteristics of the fish inhabit upstream and downstream of the dams. Signif...
