The purpose of research is determining the terms of spawning, age and morphometric characteristics of sires and rearing stocks of pikeperch ( Sander lucioperca ) gathered in one of the inlets of the Kapchagai water reservoir in 2012-2014. There were measured the mass, overall and commercial length, thickness and height of the body, head length, height of caudal paduncle, maximum body circumference. Fatness was determined, according to Fulton. To determine age there was used fish-scale. Reliability assessment of distinctions in dimensions was carried out by means of biological statistics. The terms of beginning (11-15 April) and end (20-22 April) of pikeperch spawning have been determined. The age of sires at catch is 5-9 years. There has been revealed the absence of essential dimensional distinctions in male and female pikeperch species; however, there were found distinctions in the side groups. Size indexes values of pikeperch sires from the investigated region of the Kapchagai water reservoir demonstrate polymorphism of pikeperch sires. The data obtained allow to plan rearing pikeperch juveniles breeding at all stages of production process.

Parakeets (Melopsittacus undulates) are classified parrot order Psittaciformes. Parakeets are monomorphic birds whose sex is difficult to be distinguished. Sex identification is very important for breeding efforts in order to increase the parakeet population. External morphology was determined to identify the sex of the birds. This research was conducted to determine the sex of parakeets (male and female). This study used five male and five female parakeets aged 4 months as the study objects. This study used the quantitative and qualitative method. Results of this study was verified by performing surgery to determine the sex of parakeet based on their reproductive organs. The t-test results of morphometric characteristics showed no significant different in the length of body, upper bill, lower bill, wing, tail, femur, tibial-tarsus, tarsometatarsus and digits as well as the body weight between male and female parakeets.  The color of the cere was useful to accurately determine sex in parakeets (blue in males and white in females). This research provided information to the public about the differences between male and female parakeets for the selection of good broodstock in order to increase their population in captivity.

In the foreign and native books on rowing it focuses more on investigation of body build, physical and special preparation of sportsmen. These parameters limit the passing time of a competitive distance, so they are used as qualification criteria for specialization and team batching. Methods and investigation design. Canoeists and rowers on kayaks participate in the research. The characteristics of group are: age– 19–26 years, both male and female, high sport qualification, group sizes 160 rowers of both sexes. The complex investigation includes the anthropometric measuring of total body sizes (length and body weight, chest circumference, absolute surface of the body). Conclusions. In the research the biggest length is found in Merited Sports Masters (MSM), each of male and female; the smallest – in Sports masters (SM). The similar trend was noted in parameters of body weight, in exception of single-canoe sportsmen. In this case International Masters of Sports (IMS) show the highest values. In kayaks and canoes, in teams of kayaks pairs at a distance of 200 m, the highest length and body weight were recorded in highly qualified athletes (MSM). The only exception is the body weight of female athletes-canoeists, where this figure is higher for IMS (р>0,05). Among singles at a distance of 500 m the MSM canoeists and rowers on kayaks have the best values of length and bodyweight, MS rowers have the worst results., the only exception is the maximum body length of ISM (р>0,05)/ the female ISM rowers have the highest parameters (р>0,05). The similar trend was found for kayak pairs rowers at a distance of 500 m. At a distance of 1000 m the female and male MSM rowers were superior to IMS’ and SM” in their classes, for canoe the maximum parameters of length and body weight wee noted at ISM. In teams of kayaks pairs at a distance of 1000m the size parametersof MSM are higher then ISM’ and SM’ ones.

Abstract We study size-at-age and sexual variability of morphometric characteristics of the marsh frog. According to the size of the body, males were divided into three size-age groups (juvenis, subadultus, adultus), females — into four groups (juvenis, subadultus, adultus, adultus-I). We found that the chronological age of frogs (skeletochronology) does not always correspond to their biological age (size and proportions of the body). We noted that the semi-adult males are reliably larger than females by mean values of 26 studied morphometric characters. Males and females of “adultus” group do not differ by linear body size, significant differences were found in body proportions (7 characters). For the females of “adultus-I” group, the mean values of 26 characters are significantly larger than for “adultus” males. The results of our study showed that with the age of the marsh frog, the level of exhibition, directionality and structure of morphometric sex differences changes.

ABSTRACT This report was designed to determine combined effects of maternal endocrine imbalances and abnormal behaviour due to prolonged isolation stress of female mice on the behaviour, developmental growth rate and endocrine function of their offspring. Sixty female albino mice averaging 19 g were divided equally into isolated and control groups. The isolated females were housed singly; control females were maintained in groups of 2 mice per cage. After observation of behavioural and physiological effects characteristic of isolation stress in the test mice, all isolated and control mice were mated after a 6½ month experimental, isolation period. No differences were observed in fertility and fecundity of the two groups of mothers. Analyses of developmental growth rates of the litters of the isolated versus control mothers showed significantly lower body weights in the test offspring at 3 and 4 weeks of age. The body weights of the female offspring remained significantly lower from the 4th to 11th weeks. The effects on the body weights of the male offspring declined and were no longer statistically significant at the 5th to 11 weeks. Locomotor activity at 4½ and 8 weeks of age was markedly or significantly higher in the male and female mice from isolated mothers. Tail-blood samples taken prior to autopsy at 5 and 11 weeks of age revealed significant decreases in the total leukocyte and eosinophil counts of both sexes. At the two ages, the absolute and relative spleen and thymus weights of the male and female offspring were markedly and/or significantly lower than the values observed in counterpart young from control females. Significant decreases were also observed in the absolute gonadal organ weights of both sexes at 11 weeks of age. The various data indicated inhibited growth rates, heightened locomotor activity and evasiveness, as well as evidence of increased adrenocortical function in the offspring from test mothers. The gonadal weight decreases suggested retarded gonadal development. Further studies using split-litter techniques are required to differentiate the effects of prenatal endocrine imbalances versus postnatal maternal influence (i. e., nursing care) on the offspring.

Abstract The Ityogonimus lorum-I. ocreatus co-infection is reported for the first time in the Iberian mole Talpa occidentalis in Asturias (NW Spain). Both Ityogonimus species are stenoxenous helminths of insectivores of the genus Talpa and they have often been found parasitizing the Iberian mole and also the European mole T. europaea, but a mixed infection had not been previously reported. The present study also highlights the main differential morphometric characteristics between I. lorum and I. ocreatus such as the body length, the ventral sucker diameter, the ratio between suckers and the distance between suckers.

The cardiovascular system consists of a pump represented by the heart and blood vessels, which provide the route by which blood circulates to all parts of the body. William Harvey, in the 17th century, discovered that blood is pumped away from the heart, but it all returns to the heart after circulating in the body. A right ventricular function can be compromised by pressure or stress, often secondary to the right heart valve or muscle pathology. The valves maintain unidirectional flow and permit increased pressure to develop in the chambers. The tricuspid valve consists of three tissue flaps. It separates the right atria and the right ventricle. To measure morphometric measurements of an individual leaflet of the tricuspid valve of cadaveric human hearts. The material for the present study comprised of 50 formalin-fixed adult human hearts (35 males and 15 females) which were obtained from the Department of Anatomy from various medical colleges in Maharashtra. Statistical significant difference was found for the height of anterior and posterior leaflets between male and female hearts. The length of the septal leaflet was also found to be statistically significant between male and female hearts. The study will be helpful for cardiac surgeons in providing data for tricuspid valve complex, leaflets, cords and papillary muscles.

Introduction. The most common injuries of the knee joint are injuries of the anterior cruciate ligament. The golden standard in reconstruction of this ligament is graft bone - patellar tendon - bone. Knowing the morphometric characteristics of these ligaments is crucial for anterior cruciate ligament reconstruction. This study was aimed at determining morphometric characteristics of the patellar tendon in vivo, measured intraoperatively, and at defining the correlation between the obtained values and body weight, height, gender and sport activity among different groups of athletes. Material and Methods. This study included 184 patients suffering from anterior cruciate ligament injuries who were admitted to the Clinical Center of Vojvodina, Department of Orthopedics and Traumatology. Results. The patellar tendon width ranged from 28 mm to 43 mm, averaging at 32.02 mm. The length of the patellar tendon ranged from 35 mm to 62 mm, averaging at 46.34 mm. The thickness of the patellar tendon ranged from 3 mm to 6 mm, averaging at 3.78 mm. The measured results were positively and statistically relevant with the body mass, height and body mass index. Discussion and Conclusion. The patellar tendon was thicker, longer and wider in persons with higher values of body weight and height. Men have statistically longer, thicker and wider patellar tendon than women. There was no statistically significant difference between morphometric characteristics of the patellar tendon among professional athletes and recreational athletes, neither was there one in the obtained geometric data of the patellar tendon among tested groups of professional athletes.

Abstract. Male and female BUT Big 6 and Bronze turkeys (type 1967) kept in a gene reserve were in vivoL investigated with non-invasive high resolution computerized tomography by means of a sipral CT scanner. The imaging procedure was carried out at the ages of 5, 12, 16 and 21 weeks on two turkeys, in both sexes. All animals were kept under intensive conditions according to the demands of the conformation and the body weight of the relevant group average. On the basis of 30–50 scans gathered from each bird during the scanning procedure the volumetric measurement of the total body muscle content was performed. These values were at the 5th week 0.9 and 0.8 vs. 0.3 and 0.2 dm3 in BUT male and female vs. Bronze male and female birds. At the 21st week the respective values were: 12.65 and 7.66 vs. 3.60 and 2.28 dm3. The total body fat content was characterised by the so called "fat index", a value independent of the live weight. This indices were at the 21st week: 0.12 and 0.20 vs. 0.12 and 0.13 following the above order. The investigation of the tissue development in the body was carried out by means of 3D histograms. The morphologic properties of the breast muscles were compared based on real 3D reconstructed images at the age of 21 weeks where the major differences concerned the m. pectoralis superficialis. The applied imaging methods are well applicable to describe the anatomic and body compositional differences in the excessively different genotypes.

This study examined the differences in cranial and external morphology of male and female tree squirrel species (Funisciurus leucogenys) from three different locations in Savannah vegetation zone of Nigeria. The tree squirrels were collected from contracted local hunters which identify the tree squirrel. After collection and identification to the generic level, they were transferred to the laboratory in absolute ethanol. About 183 skulls were prepared (58 male and 125 female), the skull and other body parameters were measured using digital venire calliper. The results showed that the body parameters (HBL, TL, TBL, EL, HFL, and BW) of the female specimen measured were different from male and the body parameters of the specimen from one location were slightly different from another. Also, the cranial measure showed some similarities and slight differences between male and female specimen among the locations (Asejire, Ilorin, and Ogbomosho). In conclusion, the cranial and body morphology parameters of male and female tree squirrels from the three locations (Asejire, Ilorin, and Ogbomosho) showed that despite that the tree squirrels were from different locations, they were of the same genus (F. leucogeny), which indicated that locations might not have an effect on the specimen.

<p>The African oil palm weevil,<strong> </strong><em>Elaeidobius kamerunicus</em> is an effective pollinator of oil palm. Each individual palm produces exclusively male or female inflorescence so that the success of pollination depends on the ability of the pollinator to transfer pollen from male to female flowers. The objective of this research was to study the amount of pollen carried by <em>E. kamerunicus</em> between male and female inflorescences (pollen load) and the amount of pollen carried on each part of the weevil’s body (pollen distribution). Fifty each of male and female  <em>E. kamerunicus</em> individuals were collected from male and female flowers on trees in 3 locations: Siantar (North Sumatra), Dramaga (West Java), and Morowali (Central Sulawesi). Data on pollen load and pollen distribution on the weevil’s body were analyzed using <em>ImageJ</em> software. Results show that <em>E. kamerunicus</em> individuals collected more pollen from male flowers than from female flowers. In addition, male insects carried more pollen on their bodies than female insects. Pollen distribution on weevil body parts was highest on the elytra, followed by the thorax, abdomen, legs, and head respectively.</p>
