Abstract:
Aim. The aim of the research was to study the features of formation of adaptive ability, meat productivity and quality indicators of mutton obtained in the arid conditions of the Volga region from sheep of the Edilbaev breed of different genotypes. Material and Methods. A package of teaching materials has been developed concerning an increase in the productive qualities of different genotypes of the studied breed in the conditions of arid regions of southern Russia. Results. The authors’ research has demonstrated the high adaptive abilities of animals of the Edilbaev breed, their economic and biological qualities, food and taste indicators of their meat, as well as the possibility of further development of the breed in the arid conditions of southern Russia. As a research base, we selected the Volgograd‐Edilbay LLC breeding farm (the world's only breeding and genetic center for raising Edilbaev sheep) which is located in the Volgograd region and specializes in breeding pure‐bred animals in arid steppe, semi‐desert and desert zones. Due to the great demand for the livestock of this breed from farms located in arid territories, this study of the comparative aspects of production characteristics of animals of original and new types in the arid conditions of the Volga region is of interest to both science and practical animal husbandry. Conclusion. An assessment of the nutritional value of mutton obtained from animals of the Edilbaev breed has shown its high nutritional and biological qualities.

Abstract:
Energy conservation is a key adaptation for desert survival in the Bedouin goat. When food is scarce, metabolism is reduced and body weight can be maintained indefinitely on less than one-half of normal intake. We hypothesized that metabolism would be turned down during both rest and exercise, but it was not. It was low when animals rested and returned to normal during exercise. We expected catecholamines and thyroid hormones would modulate metabolism, but they did not. The reduction in metabolism preceded any change in thyroid hormone concentrations, and infusions of epinephrine did not restore reduced metabolism to normal levels. Finally, we expected the gut would be the major organ system involved in the metabolic reduction because less food is eaten, processed, and absorbed. Contrary to our expectations, we found that muscle is the primary organ system responsible for the reduction. It appears that the adaptations of the Bedouin goat for surviving on limited food supplies involve different organ systems and different modulators to reduce metabolism from those known for other mammals.

Abstract:
SUMMARYChanges in body weight and body temperature were observed in Sudanese desert sheep and goats, which had been subjected to the summer sun (20 °C min. to 42 °C max.), given water normally and then deprived of water for 3 days. Tritiated water was also used to measure total body water and water turnover in these animals together with measurements of plasma and extracellular space, intracellular fluid volume and blood osmolality. The body weight and the size of the fluid compartments decreased in the two species at varying degrees associated with haemoconcentration. The extent of some changes was more marked in sheep than in goats, suggesting better adaptation of the former species to desert life.

Abstract:
During dynamic terrestrial locomotion, animals use complex multifunctional feet to extract friction from the environment. However, whether roboticists assume sufficient surface friction for locomotion or actively compensate for slipping, they use relatively simple point-contact feet. We seek to understand and extract the morphological adaptations of animal feet that contribute to enhancing friction on diverse surfaces, such as the desert locust (Schistocerca gregaria) [Bennet-Clark HC (1975) J Exp Biol 63:53–83], which has both wet adhesive pads and spines. A buckling region in their knee to accommodate slipping [Bayley TG, Sutton GP, Burrows M (2012) J Exp Biol 215:1151–1161], slow nerve conduction velocity (0.5–3 m/s) [Pearson KG, Stein RB, Malhotra SK (1970) J Exp Biol 53:299–316], and an ecological pressure to enhance jumping performance for survival [Hawlena D, Kress H, Dufresne ER, Schmitz OJ (2011) Funct Ecol 25:279–288] further suggest that the locust operates near the limits of its surface friction, but without sufficient time to actively control its feet. Therefore, all surface adaptation must be through passive mechanics (morphological intelligence), which are unknown. Here, we report the slipping behavior, dynamic attachment, passive mechanics, and interplay between the spines and adhesive pads, studied through both biological and robotic experiments, which contribute to the locust’s ability to jump robustly from diverse surfaces. We found slipping to be surface-dependent and common (e.g., wood 1.32 ± 1.19 slips per jump), yet the morphological intelligence of the feet produces a significant chance to reengage the surface (e.g., wood 1.10 ± 1.13 reengagements per jump). Additionally, a discovered noncontact-type jump, further studied robotically, broadens the applicability of the morphological adaptations to both static and dynamic attachment.

Abstract:
Abstract Venezillo arizonicus (Mulaik & Mulaik, 1942) is the only oniscidean isopod native to the Southwest Desert Province of North America. In accordance with its desert habitat, we hypothesized that V. arizonicus would have a higher upper lethal temperature than mesic oniscideans. If oniscidean thermal tolerance is limited by an oxygen consumption-uptake mismatch (physiological hypoxia), as indicated by recent work with other land isopods, we further hypothesized that V. arizonicus would possess highly efficient pleopodal lungs, as defined by its capacity for metabolic regulation in reduced . Other adaptations to counter oxygen limitation at high temperatures could include reduced temperature sensitivity of metabolism (low ) and an overall reduction in metabolic rate. Thermal tolerance was measured using the progressive method of Cowles & Bogert and the catabolic rate of animals () was measured as a function of temperature and . The critical thermal maximum (CTmax) of winter-acclimatized animals was 43.0 ± 0.85°C, 1.6-2.6°C higher than published values for summer-acclimatized mesic oniscideans. The catabolic rate at 25°C was 1.50 ± 0.203 μl min−1 g−1, markedly lower than values determined for mesic Oniscidea (4-6 μl min−1 g−1) and was unaffected by hypoxia as low as 2% O2 (ca. 2 kPa). Catabolism was, however, quite sensitive to temperature, showing a mean of 2.58 over 25-42°C. The efficient pleopodal lungs and low metabolic rate of V. arizonicus will both tend to mitigate physiological hypoxia, consistent with the species’ high CTmax. A low catabolic rate may also be an adaptation to low habitat productivity and seasonally constrained activity patterns.

Abstract:
The Republic of Tyva is a region in the geographical center of Asia, which located at the junction of the Siberian taiga and Central Asian desert-steppe landscapes, in a wide band of mountains and intermountain plains. The mountain-forest area of Tyva has long been considered a natural habitat for antler deer, one of which is the maral (Cervus elaphus sibiricus). In order to restore maral breeding and increase the number of marals in the former limits, marals of the Altai-Sayan breed have been imported to the Republic of Tyva from the Republic of Altai. The preservation of productive traits, reproductive function and the realization of the genetic potential of animals introduced to new climatic conditions largely depends on the ability of these animals to adapt to existing environments. We have assessed in this paper the natural resistance of the marals of Altai-Sayan breed during introduction in the Tyva Republic in comparison with the indicators of the marals have been bred in the Altai Republic. The researches have been carried out in 2019. The research material was blood samples of marals of Altai-Sayan breed imported to the Republic of Tuva (n=27) and marals of the same breed bred in the Republic of Altai (n=17). Studies have shown some deviations in the blood leukogram of imported marals, such as a decrease in the number of eosinophils and rod nuclear neutrophils (P < 0,001), the increase in the number of segmented nuclear neutrophils and lymphocytes (P < 0,05). The number of monocytes have been increased in 18,6 times compared to the Altai marals. The change in the number of monocytes exceeded the physiological norm by 24,7 %. The indicator of adaptation evaluation in imported marals had higher values (6,8), which were in 1,7 times higher than in marals bred in the Altai Republic (4,1), which indicates the intensity of adaptive mechanisms in imported animals during adaptation. Analysis of phagocytic activity and phagocytic index revealed intensive phagocytosis in imported marals: phagocytic activity – by 12,4 % (P < 0,05), phagocytic index – by 5,1 %, and the increase in the content of lysosomal and cationic proteins by 12,8 % (P < 0,05). Analysis of the bactericidal activity of blood serum has shown its lower level in imported animals (45,97±1,36 %), compared with marals of the same breed bred in the Altai Republic (52,19±2,15 at P < 0,05). Thus, according to most indicators of natural resistance marals of Altai-Sayan breed imported to Tyva have a fairly high level of natural protection, which indicates that they can be adapted to the natural climatic and feeding conditions of the Republic of Tyva.

Abstract:
Endothermic homeothermy is a major feature of the adaptive suites of tachymetabolic animals such as mammals and birds. The advantages homeothermy confers on birds and mammals include relative independence from the environment, a stable internal milieu, and possibly the ability to sustain high aerobic activity (Bennett and Ruben 1979). Some mammals in situations of limited water or energy availability, however, depart markedly from homeothermy and instead display patterns of heterothermy. Torpor is a lowering of body temperature (T(b)) to conserve energy and/or water. I studied the energetics of arousal from torpor in two desert pocket mice species. The species differed in warming rates and arousal durations, but used similar amounts of energy to arouse. The smaller species, Perognathus amplus, lost mass more quickly while fasting in the cold, yet waited as long as the larger species, Chaetodipus baileyi, before entering torpor. P. amplus maintained a lower T(b) during topor than C. baileyi. The thermodynamics of arousal indicated that metabolic rate during arousal was a function of T(b) but not ambient temperature (Tₐ), that the animals changed thermal conductance to increase heat gain when Tₐ was greater than T(b), and that Q₁₀ decreased during arousals. In contrast to torpor, adaptive hyperthermia provides desert mammals in dry, hot environments a means to conserve water that would normally be used for evaporative cooling. I modeled the effects of body size on adaptive hyperthermia and discovered that small mammals gain the most in terms of water savings using this strategy, and that small and large mammals can spend larger fractions of the day active than do medium size mammals. I demonstrated that two desert ground squirrel species make use of adaptive hyperthermia during the summer near Tucson, Arizona by following free-ranging squirrels implanted with temperature-sensitive radio transmitters. Ground squirrel T(b) fluctuated almost continuously, ranging from about 35°C to over 42°C, and rarely approached steady state. Of the two species studied, Ammospermophilus harrisii had higher mean T(b), similar maximum T(b), and lower T(b) variability compared to Spermophilus tereticaudus. These results are consistent with the more wide-ranging foraging style of A. harrisii compared to S. tereticaudus.

Abstract:
The distribution of desert species of plants and animals in the Ulyanovsk region (Middle Volga region) is associated with two main reasons: native origin and penetration (entry) from arid and semiarid regions. Deserted species of indigenous origin, as a rule, are located on the northern border of the range and move north along similar biotopes - salt marshes, saline steppe areas, arid steppes with elements of semi-deserts, etc. Most of these species are rare and are listed in the regional Red Book. Intertile desert species are often occupied by ruderal biotopes - silver goof, tamarix, etc. In general, in the biota of the Ulyanovsk region, desert species account for about 5%.
