Sexual Dimorphism in Morphometric Characteristics of Korean Chub Zacco koreanus (Pisces, Cyprinidae)

The Study of Sexual Dimorphism in The Morphometric Characteristics of the Skull of the Male and Female Zell Sheep

Introduction: The aim of the present study was to evaluate the morphometric differences of the skull in male and female Zell sheep. Methods: For this purpose, 30 heads (15 adult males and 15 adult female) of Zell sheep breed were collected from the local slaughter-house. The skulls were prepared using the boiling maceration according to the usual techniques, and the mandible was dissociated fr...

Sexual Dimorphism Using Geometric Morphometric Approach

Sexual dimorphism of the suprascapular notch – morphometric study

INTRODUCTION The concept of the study was to compare the morphometry of the suprascapular notch (SSN) in females and males because its size and shape may be a factor in suprascapular nerve entrapment. MATERIAL AND METHODS The measurements of 81 scapulae included morphological length and width, maximal width and length projection of the scapular spine, and width and length of the glenoid cavit...

Setting Conservation Priorities in a Widespread Species: Phylogeographic and Physiological Variation in the Lake Chub, Couesius plumbeus (Pisces: Cyprinidae)

Defining units of conservation below the species level is a widely accepted conservation priority, but is especially challenging for widespread taxa that have experienced diverse geographic histories and exist across heterogenous environments. The lake chub (Pisces: Couesius plumbeus) is a widespread freshwater fish in North America and occurs from the southcentral USA to northwestern Alaska an...

Magnetic Resonance Imaging-Based Morphometric Assessment of Sexual Dimorphism of Corpus Callosum

Introduction: Interhemispheric transmission of signal is done by corpus callosum (CC) as the largest fiber tract in brain. CC comprised 5 segments of rostrum, genu, body, isthmus, and splenium. Contradictory reports exist about sexual dimorphism of CC. We designed this study to assess probable sexual differences of CC and its different parts in men and women. Methods: We analyzed magnetic reso...
