A comparison of traditional and geometric morphometric techniques for the study of basicranial morphology in horses: a case study of the Araucanian horse from Colombia [PDF]

, 2020
Skull size and shape have been widely used to study domestic animal populations and breeds. Although several techniques have been proposed to quantify cranial form, few attempts have been made to compare the results obtained by di erent techniques. While

Morphological differentiation between seven Brazilian populations of Haemagogus capricornii and Hg. janthinomys (Diptera: Culicidae) using geometric morphometry of the wings

Revista da Sociedade Brasileira de Medicina Tropical, 2019
INTRODUCTION: Haemagogus capricornii and Hg. janthinomys females are considered morphologically indistinguishable. We analyzed morphometric variability between Brazilian populations of these species using wing geometric morphometry.

Use of Nuclear Magnetic Resonance Imaging Angiography to Follow-Up Arterial Remodeling in an Animal Model [PDF]

, 1998
Appropriately sized arteries in small animals may be possible models for studying the remodeling process as occurs after arterial balloon injury in humans. Magnetic resonance imaging (MRI) is able to noninvasively image tissue in vivo.

DNA barcodes combined with geometric morphometry challenge species hypothesis in palaemonid shrimp [PDF]

ARPHA Conference Abstracts, 2021
Although the Mediterranean Region is known as a hotspot for biodiversity and endemism its freshwater fauna is still greatly unexplored, and even the emblematic taxa such as decapods require in-depth integrative investigation. In our research we used integrative approach composed of various geometric morphometric and molecular methods to challenge the ...

Geometric morphometry as a new method of differentiation of intrabreed types in horse breeding [PDF]

BIO Web of Conferences
Assessment of type severity and exterior correctness is a necessary breeding measure in breeding work with breeds. Traditionally assessed features demonstrate subjectivism.

Diversity and Geographical Distribution of Sand Flies Phlebotomus papatasi (Diptera: Phlebotominae) by using Geometric Morphometric Technique from two Iraqi Provinces

مجلة بغداد للعلوم, 2020
The variation in wing morphological features was investigated using geometric morphometric technique of the Sand Fly from two Iraqi provinces Babylon and Diyala . We distributed eleven landmarks on the wings of Sand Fly species.

Morphological characterization of ticks of the genus Rhipicephalus (Boophilus) based on geometric morphometry: the case of the Savannah District in Côte d’Ivoire

Journal of Entomological and Acarological Research, 2023
The introduction of the invasive tick Rhipicephalus (Boophilus) microplus in Côte d'Ivoire has led to a change in the population of ticks of the genus Rhipicephalus (Boophilus).

Investigation of Os Coxae in Horses Using Geometric Morphometry Method

Harran Üniversitesi Veteriner Fakültesi Dergisi, 2020
In contrast to normal morphometric measurements, geometric morphometry is a method that can explain the differences and variations on the x-y coordinates of the specified points on a 2D plane. In this method, two-dimensional samples, such as pictures or x-rays, are used.
