Abstract:

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 different techniques. While linear morphometrics has traditionally been used in breed characterization, recent advances in geometric morphometrics have created new techniques for specifically quantifying shape and size. The objective of this study was to compare two morphometric methods for their ability to describe external morphology. For this purpose, 20 skull specim

Abstract:

Morphometric characters of fishes are measurable or metric characters. Morphometrics is a more or less interwoven set of large statistical procedures to analyze variability in the size and shape of organisms. Morphometrics and phylogenetics of a species are combined to utilize existing phylogeny which addresses hypotheses of shape change through evolutionary time. Morphometric differences among stocks of a species are recognized as important to evaluate population structure and form a basis to identify stocks. Advancements in morphometrics used powerful tools for testing and displaying differe

Abstract The aim of this study was to quantify sub-resolution trabecular bone morphometrics, which are also related to osteoarthritis (OA), from clinical resolution cone beam computed tomography (CBCT).

Three ageing techniques were tested on samples of wild-caught feral pigs from subalpine (n =35) and semi-arid (n =64) areas in eastern Australia, and on a sample of known-age captive feral pigs reared from stock from semi-arid areas (n =15). Techniques employed were based on morphometric relationships, patterns of tooth eruption and wear, and counts of cementum lines in permanent incisors. Cyclic seasonal conditions led to apparently annular cementum line deposition for pigs from the subalpine area. In contrast, stochastic variation in seasonal conditions led to irregular cementum line deposit

Abstract:

This study investigates the morphometric variation of osteoderms across species and populations within the genus Acontias, especially in the A. meleagris species complex. Using both univariate and multivariate analyses, we evaluated whether size-independent osteoderm morphometrics could effectively differentiate taxa, particularly where minimal genetic divergence is present (i.e., cases where morphologically diagnosable species show little genetic separation). Univariate analysis revealed some significant morphometric variation across osteoderm regions, with sub-regions C and D showing the hig

Abstract This study investigates the biometrics of the common smooth-hound shark, Mustelus mustelus, from fish landing sites of the Lagos and Ondo Coasts. Morphometric measurements and meristic counts were used on 1,018 specimens to analyze morphometric differentiations. Significant sex-based differences were found across various morphometric traits, with phenotypically separable populations observed between locations. Bray-Curtis analysis categorized morphometrics into four groups based on similar characteristics. Principal component analysis identified three components, with PC1 dominated by

Abstract:

The present study investigated the biology and morphometric analysis of rugose spiralling whitefly (RSW), Aleyrodicus rugioperculatus on coconut under mini net house condition at Department of Agricultural Entomology, Tamil Nadu Agricultural University-Coimbatore during 2019-2020. The biology of rugose spiralling whitefly was studied by clip cage method and morphometrics were done using Leica image analyser. Total lifecycle of rugose spiraling whitefly was 56.23 ± 2.20 days. Developmental period of egg, nymphal, pupal and adult period was 8.47 ± 0.26, 17.46 ± 0.76, 10.30 ± 0.29 and 20.00 ± 1.0

Abstract:

Analysis of animal morphometrics can provide vital information regarding population dynamics, structure, and body condition of cetaceans. Unmanned aerial vehicles (UAVs) have become the primary tool to collect morphometric measurements on whales, whereas on free ranging small dolphins, have not yet been applied. This study assesses the feasibility of obtaining reliable body morphometrics from Australian snubfin (Orcaella heinsohni) and humpback dolphins (Sousa sahulensis) using images collected from UAVs. Specifically, using a dolphin replica of known size, we tested the effect of the altitude

Abstract:

Morphometry is introduced as quantitative approach to seek information concerning variations and changes in the forms of organisms that described the relationship between the human body and disease. Scientists of all civilization, who existed until today, examined the human body using anthropometric methods. For these reasons, anthropometric data are used in many contexts to screen for or monitor disease. Anthropometry, a branch of morphometry, is the study of the size and shape of the components of biological forms and their variations in populations. Morphometrics can also be defined as the

Indonesia, a nation predominated by water, earning it the designation of a maritime country. It boasts a rich variety of marine life, including numerous fish species. The Bali Waters, part of Indonesia's marine territory, are home to a diverse range of fish species. Lemuru (Sardinella sp.) is a common fish group found in the southern waters of Bali. These lemuru are typically landed at the Kedonganan Fish Landing Site. Fish residing in specific regions often exhibit unique morphometrics and growth patterns. The objective of this study is to delineate the morphological characteristics and morph

Previous attempts to resolve the Ceratitis FAR complex (C. fasciventris, C. anonae, C. rosa, Diptera, Tephritidae) showed contrasting results and revealed the occurrence of five microsatellite genotypic clusters (A, F1, F2, R1, R2). In this paper we explore the potential of wing morphometrics for the diagnosis of FAR morphospecies and genotypic clusters. We considered a set of 227 specimens previously morphologically identified and genotyped at 16 microsatellite loci. Seventeen wing landmarks and 6 wing band areas were used for morphometric analyses.
