in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Gully erosion is one of the most significant erosion types. This type of erosion is one of the most important sources of sediment in different regions of the world. Gullies often have different dimensions and complex characteristics and these characteristics may affect the distribution of vegetation. Topographic characteristics of gullies provide complex ecosystem for vegetation establishment. ...
this research explains the morphometric characteristics of varroa destructor anderson and trueman in tehran province. 180 adult female mites were collected from three different colonies of apis mellifera l. in three apiaries during september 2003 to may 2004. these colonies were divided according to three altitudes-less than 1000m, 1000-1500m and more than 1500m above the sea level. the morphol...
We have quantified the ultrastructure of myocardial cells in tissue samples obtained from six adult normal Yucatan swine. Tissue samples were obtained from 20 different sites in the left ventricle, right ventricle, and interventricular septum. The samples were processed for electron microscopy and quantitative morphometric analysis. The percent relative volumes of myofibrils, mitochondria, tran...
IMPORTANCE Morphometric assessment has emerged as a strong predictor of postoperative morbidity and mortality. However, a gap exists in translating this knowledge to bedside decision making. We introduced a novel measure of patient-centered surgical risk assessment: morphometric age. OBJECTIVE To investigate the relationship between morphometric age and posttransplant survival. DATA SOURCES...
the black-striped pipefish, syngnathus abaster, is a species of the syngnathidae family. this study provides data on the morphometric, meristic and genetic structuring of the caspian sea pipefish, syngnathus abaster. eight morphometric characteristics based on total length and five morphometric characteristics based on standard length were analyzed. a total of 50 specimens were collected in bra...

Prioritization of sub-watersheds is very important and necessary in order to implement soil and water conservation practices. This study has prioritized 13 sub-watersheds based on morphometric and land use characteristics using RS and GIS techniques in Haraz watershed to identify erosion-prone sub-watersheds. Morphometric characteristics including bifurcation ratio, drainage density, stream fre...
study of fishes on aquatic ecosystems in many respects, including ecology, behavior, biology, conservation and management of water resources, exploitation of resources and training are important. so in the autumn 2011, the population structure of barilius mesopotamicus was studied. in this order, 69 samples of the mentioned fish from seimareh (34 samples), changoleh (20 samples) and siahgave (1...
