Morphometric measurement

Despite clinical importance and frequent occurrence of sinus disease, little is known about the size of paranasal sinuses and their communication in ponies and small horses. To examine the shape and volume of the paranasal sinuses and evaluate the sinonasal communication, three-dimensional (3D) reconstructions of computed tomography (CT) datasets of 12 healthy adult Shetland ponies were performed and analysed.

The Redshank is a wader species that shows no sexual dimorphism in plumage, but some dimorphism in size. To propose a method for sexing birds of this species by linear measurements, a discriminant function analysis was applied to a set of morphometric traits in birds captured during the spring migration in southern Belarus. In total, 113 males and 75 females were measured and sexed molecularly. On average, females were larger in all measurements than males. The most sexually dimorphic trait was wing length, which was included in the discriminant function analysis.

In a moss sample collected from Mount Kulal in Kenya, a new population of Mesobiotus radiatus was found. Given that the original description of M. radiatus was based solely on the morphology observed by light microscopy and measurements based mostly on a single individual, here we describe the new population by means of integrative taxonomy and a large sample size.

To better determine the ecological variation (body shape and structure) of the Vieja Azul (Andinoacara rivulatus; syn.: Aequidens rivulatus) in northwest Ecuador (Los Ríos Province), 300 specimens of both sexes (150 male and 150 female) were collected from 3 different locations, one from a wild production system and two from fish farm populations in the Quevedo River. Twelve meristic, 26 traditional morphometric, and 32 truss measurements, among 25 anatomical landmarks, were determined.

The study aimed to investigate morphometric and meristic variability in the mud sleeper Butis koilomatodon (Bleeker, 1849) in the Mekong Delta. This species is a commercial fish species with a small-size and is mainly distributed in some coastal areas from Tra Vinh to Ca Mau provinces. In the present research, the parameters of morphometry and measurement, including the head length, body depth, eye diameter, distance of the two eyes, and the interrelationships among the morphometric variables, were determined.

The present study was conducted to investigate the effect of dietary supplementations of inorganic, organic and nano Zn on carcass characteristics and bone morphometric study in broiler chickens. A total of 300 day-old straight run broiler chicken were randomly assigned to 10 dietary treatments each consisting of 3 replicates and each replicate having 10 chicks for a period of 6 weeks.

Knowledge about the morphological adaptations of body and wing in birds helps to know about their aerodynamic performance. The present study was aimed to analyze the morphometry of the wing of the blue and yellow macaw (Ara ararauna) with reference to aerodynamics. Various aerodynamic measurements namely body weight, body length, wing span, wing area, wing load and aspect ratio were measured in three adult male birds. The wings were short, elliptical and rounded.

Studies on the biology of Corcyra cephalonica on three sesamum (Sesamum indicum) varieties viz. Smarak (white), Amrit (brown) and Prachi (black) were carried out. The mean duration of egg, larval, pupal and adult period of Corcyra cephalonica were recorded 3.67, 27.73, 7.80 and 6.80 days on variety Smarak, 5.00, 28.73, 8.73 and 7.60 days on variety Amrit and 5.80, 30.13, 10.40 and 8.40 days on variety Prachi respectively.

A total 200 soil samples were collected from tea plantation areas of district, Jorhat, Assam and were assessed for entomopathogenic nematodes using the Galleria baiting technique. Out of 200 soil samples, EPN was found in 1 soil sample collected from Tea plantation, Chetiagaon, Jorhat and designated as EPN-H-1. Morphological and morphometrical characters were used for the identification of nematode isolate. The measurements were expressed in % ratios and Means ± SD ranges.

An image analysis technique is well suited for the collection of data concerning the shape and size of the seeds. Such morphological data is often used for establishing the distinctness of new varieties. Seed morphometric characters like seed length, breadth, length to breadth ratio (seed shape) and thousand seed weight were determined for hundred rice genotypes by using Biovis image analyser.

The study, estimated to contribute to generate information to elucidate morphometrics and length-weight relationship and the relative growth of some body parts of the mud crab Scylla serrata. A total of 100 crabs were collected, from January 2018 to January 2019, from Sudanese Red Sea coast of the commercial catch land at Port Sudan. Each specimen was sexed and measured.
