A defining feature of species is that their constituting populations are connected by gene flow. However, interspecific gene flow (introgression) can affect species integrity. If some genome components were less prone to introgression than others, they should be particularly suitable to delimitate species. Recent simulation studies have predicted a negative correlation between intra- and inters...

INTRODUCTION Our aim was to compare changes of body mass index (BMI) and waist circumference (WC) curves of Iranian children by comparing the results of two national surveys of a surveillance program, i.e. CASPIAN-I (2003-2004) and CASPIAN-III (2009-2010). The second objective was to evaluate the prevalence of obesity, overweight and underweight among 10-18-year-old Iranian children and adolesc...

Problem statement: Uterine cervix which separates the uterus from the vagina, shows remarkable anatomical and histological differences among mammalian species. Since no cleared observations have been found in regards with the Caspian miniature horses’ cervix, the aim of the present study was to supplement this missing information which could be helpful for providing a stricter basis in detectin...

—During November 2002, 51 shovelnose sturgeon Scaphirhynchus platorynchus were sexed by ultrasound imaging using a portable ultrasonograph. We identified males with 96% accuracy (N 5 25) and females with 80% accuracy (N 5 25); one hermaphroditic individual was misidentified as a male. Overall, ultrasound imaging was 86% accurate. Sex in postspawned females was difficult to determine, 60% being ...
