Abstract Cherax quadricarinatus is an introduced species that deliberately stocked in Lake Laut Tawar, Takengon, Indonesia. This study aims to analyze bio-population aspect of this species, including length frequency distribution, length-weight relationship, condition factors, and biology reproductive. A total 361 individual was sampled bi-weekly from October December 2021 Central Aceh, The car...

fourteen different morphological traits in 169 and 131 cattle of oulmes-zaer and tidili, respectively were recorded and analyzed using a multivariate approach. the characters measured included heart girth, wither height, rump height, rump length, rump width, chest depth, body length, neck length, cannon circumference, ear length, ear width, head length, horn length and tail length. breed signif...

The geometric morphometric analysis of the shell of Caretta caretta hatchlings revealed that morphological variations may be related to incubation duration. Based on the overlapping of anatomical landmarks of the carapace and the plastron, it was possible to discriminate hatchlings from slow and fast developing clutches. Carapace and plastron of hatchlings from nests where incubation lasted les...

in this study, by examining the character of the morphometric and meristic characters of garra variabilis samples which is obtained from different locality in tigris river, morphometric characters which are transformed, subjected to discriminant analysis and depending on grouping model, number of discriminant functions and according to importance of these in terms of explaining total variance, ...

Some new foods (sprouts, microgreens and baby leaf) of the brassica genus are appreciated for their nutritional nutraceutical values. The aim this experimental trial was to improve traits these by evaluating effects climatic condition, genotype, plant growth stage on development greater quality in relation foods. morphometric glucosinolates (GLSs) three traditional Italian cultivars Brassica ol...

Twelve cultivars of bambara groundnut were sown for evaluation of variability and genetic correlation among agronomic characters and seed yield in 2004 and 2005 in a randomized complete block design with three replications. Combined analysis of variance revealed highly significant effects (p<0.05) for genotypes (G), year (Y) and G x Y interaction for most characters evaluated. Estimates of geno...

A 2W cw laser diode (LD) with an external cavity produced by a reflecting volume Bragg grating (VBG) demonstrated a spectral width of 7GHz (full width at half-maximum) at 780nm. The device output power exceeded 90% of the output power of the free-running LD. The emission wavelength was tuned over a 300pm range by thermal control of the VBG. Rb vapor was shown to absorb more than 95% of the lase...

this study was designed to evaluate population variation and differentiation of bartail flathead, platycephalusindicus (linnaeus, 1785)in the iranian waters of the persian gulf using the morphometric and meristic characters. a total of 180 fish were collected by gill net from six stations (khormosa, bahrekan, shif, motaf, charak and bandar abbas) of iranian coasts of persian gulf including 30 f...

Four species of Cymo, associates of scleractinian corals, from the Red Sea were studied using scanning electron and light microscopy. Characters based on the morphologies of the carapace, gonopods and digestive tract (gastric teeth) were investigated and described in detail. All Red Sea species are redescribed, distinguishing characters are identified and an identification key is provided. Cymo...
