Facial morphometry using computerised image analysis was performed on patients with growth hormone receptor deficiency (Laron syndrome) from an inbred population of southern Ecuador. Morphometrics were compared for 49 patients, 70 unaffected relatives, and 14 unrelated persons. Patients with growth hormone receptor deficiency showed significant decreases in measures of vertical facial growth as...

 Mahisefid, Rutilus frisii kutum , is a cyprinid fish which is distributed from Turkmenistan to Azerbaijan along the Caspian Sea. It is one of the economically important fish in the region. As part of the Iranian Fisheries Company’s policy to improve the stocks of this species, every year, fingerling of Mahisefid are released into the southern basin of the Caspian Sea. The main objective of thi...

In taxonomy, qualitative methods are commonly used to analyze morphological characters, which can lead dramatic changes in higher taxa. Geometric morphometrics (GM) has proven be useful for discriminating species various taxonomy groups. However, the application of geometric supraspecies classification is relatively scarce. this study, we tested controversial two subgenera Chaetocnema with morp...

Backed flakes (core edge and pseudo-Levallois points) represent special products of Middle Paleolithic centripetal flaking strategies. Their peculiarities are due to their roles as both a technological objective in the management core convexities retain its geometric properties during reduction. In contexts, these backed implements commonly produced Levallois discoidal reduction sequences. from...

Based on their morphological and genetic similarity, several studies have proposed that Lutjanus campechanus purpureus are the same species, but there is no confirmed consensus yet. A population-based study concerning otolith shape analyses was used to evaluate if L. species. Samples were collected from populations in southwestern Gulf of Mexico Venezuelan Caribbean. Otolith evaluated by tradit...

‘Traditional morphometrics’ allows us to decompose morphological variation into its major independent sources, identifying them usually as size and shape. To compare and investigate the properties of size and shape in natural populations of Drosophila takahashii, estimating their seasonal changes, we carried out collections on two different occasions i.e. winter and summer. In the present study...

The fish species Symphodus bailloni (Valenciennes, 1839) reported in the present study were collected between June 2010 and June 2011 from the western Black Sea coasts which were previously not recorded from the Black Sea coast of Turkey. A total of 717 specimens of S. bailloni were measured, ranging between 8.9 and 15.4 cm TL. Morphometrics, meristics, and diagnostic characteristics of the spe...
