The expensive tissue hypothesis predicts a trade-off between investments in the brain and other energetically costly organs due to the costs associated with their growth and maintenance within the finite energy resources available. However, few studies address the strength of relationships between brain size and investments in precopulatory (ornaments and armaments) and postcopulatory (testes and ejaculates) sexual traits. Here, in a broad comparative study, we tested the prediction that the relationship between brain size and investment in sexual traits differs among taxa relative to the importance of sperm competition within them. We found that brain size was negatively correlated with sexual size dimorphism (SSD) in anurans and primates, and it tended to decrease with SSD in ungulates and cetaceans. However, brain size did not covary significantly with armaments (e.g., canine length, horn, antler, and muscle mass). Brain size was not correlated with postcopulatory sexual traits (testes and ejaculates). The intensity of covariance between brain size and precopulatory sexual traits decreased with increasing relative testis size.

Parasites can dramatically influence fecundity of their hosts, so for any host species it is important to establish whether parasite infections affect host reproduction. The Pacific mole crab, Emerita analoga, commonly harbors metacercarial cysts of the trematode Microphallus nicolli and cystacanths of the acanthocephalan Profilicollis altmani. Although these helminths are known to infect primarily larger female mole crabs, they may do so disproportionately when tied to their host’s reproductive condition. This study was undertaken to examine differences in parasite prevalence and abundance between non-ovigerous and ovigerous hosts. Crabs from Del Monte Beach, Monterey, California were collected, carapace length measured, sexed, examined for parasites, and had their reproductive state noted. The vast majority of the crabs sampled were infected with at least one parasite, and over half of the crabs had both M. nicolli and P. altmani. Ovigerous females were significantly larger than non-ovigerous crabs. Prevalence of both trematode metacercarial cysts and acanthocephalan cystacanths was significantly higher in ovigerous females than in non-ovigerous ones. Egg-bearing females were also more heavily infected by both parasites than non-egg-bearing individuals. These results suggest that larger ovigerous crabs may provide greater resources and thus are able to support higher levels of infections. This study shows that neither parasite prevalence nor abundance seemed to affect egg production in E. analoga.

Ecogeographical rules predict an association between specific adaptive morphological/physiological traits and latitude, elevation or cooler climates. Such ecogeographical effects are often expressed most clearly in widely distributed species due to continuous selective adaptation occurring over their geographic range. Based on 40 population sampling sites of 116 adult individuals (female, ; male, ) across an elevational range of 191–2573 m, we tested whether morphological traits accorded with predictions of Bergmann’s rule, Allen’s rule and Hesse’s rule for the South China field mouse (Apodemus draco). The effects of elevation on body size, appendage length and heart size were tested by fitting Linear Mixed-Effects Models. None conformed to Bergmann’s, Allen’s or Hesse’s rule. Clines in body size opposed Bergmann’s rule, and foot and snout length ratios opposed Allen’s rule. We conclude that South China field mice, a widely distributed species, exhibit an acute thermoregulation mechanism in which in colder conditions body sizes decrease – as opposed to altering heart sizes or surface area to volume ratios – requiring less energy to regulate body temperatures. Also, there was a stronger selective pressure to increase partial appendage lengths (i.e., foot and snout) to adapt to the specific environment (e.g. longer period of snow cover, up to 2573 m) rather than on a general shortening of appendages to cope with colder conditions.

The largest muscles in fowl are the pectorals, which provide the power required for birds to fly. Tibetan chickens show specific adaptations to high-altitude conditions, but changes in the muscle transcriptome associated with these adaptations have not been characterized yet. Therefore, in this study, we used next-generation sequencing technologies to generate eight libraries of mRNA sequences for four Tibetan chickens and four Beijing fatty chickens. A comprehensive transcriptome analysis was performed. In the eight samples, 12 333 annotated protein-coding genes were expressed. Among these, 48 differentially expressed genes were found; all of which were upregulated in Tibetan chickens. These differentially expressed genes were mainly involved in kidney morphogenesis, which indicates that hypoxia has an important effect on renal tubule development. Only nine genes were involved in Kyoto Encyclopedia of Genes and Genomes pathways, such as the endocytosis pathway, the MAPK signaling pathway, the calcium signaling pathway and the TGF-beta signaling pathway. The differentially expressed genes identified in this study will be used to facilitate future research into the Tibetan chicken.

Morphometry can help to understand morphology and clarify taxonomy of species. The morphometric variability of the skull and sexual dimorphism of stone martens (Martes foina), obtained from various geographical regions of Turkey, were investigated. Measurements were made regarding 14 characters on skulls of the samples. Adults have significantly bigger skulls compared to juveniles. Regarding their sexual dimorphism, descriptive statistics revealed variability in the size of the skull between sexes, with mean values of males being higher than those of females. The most significant sexual dimorphisms (the highest variabilities) were observed in palatal width and especially frontal width. The strongest positive correlations were found between the basilar length and condylobasal length in males and between the mandibular length and total skull length in females. Furthermore, principal component analysis confirmed strong correlations between some characters of the skull in both sexes. By comparing characters with those of European populations this study contributes to a general model of the skull of Martes foina.

Charkin Volodymyr was PhD in Biology, Senior researcher, Head of the Laboratory of Cattle Nutrition that focuses on researching the physiology of animal lactation, studying the influence of Iodium, Chromium, Selenium, Cobalt on metabolic processes, productivity and composition of milk; development of elements of national protein feeding system of high productive cows that correspond to modern protein standardizing criteria. Lactation is a complex process of creation, storing and producing milk in animal’s mammal gland. Nervous system and hormones of endocrine glands with the help of brain cortex and hypothalamus, where lactation center is located, regulate the process of mild production. Hypothalamus produces releasing factors – somatoliberin and prolactoliberin that stimulate the production of hormones somatotropin and prolactin in hypothesis. These hormones directly take part in the production of milk. The role of other endocrine glands is that they contribute to promotion of the synthesis of milk precursors and increase of their amount in blood.

One of the stages of research work dealt with studies of metabolism processes and fertility in birds in connection with protein, amino acidic and mineral nutrition of different age, breed and fertility groups of birds. When researching metabolism of mineral sulfur in bird organism, he for the first time conducted a complex study of biochemical mechanisms of exogenous suplhate impact on bird organism with regard for the amount of protein, sulfur-content amino acids and total sulfur in diet by methods of radiology, biochemistry, physiology and nutrition. Theoretical foundations and practical recommendations have been developed on improving efficiency of sodium sulphate use in feed of birds of different age, type and productivity direction.
