Summary: Recent research has shown inconsistencies in virus-host phylogenies, possibly due to adaptive radiation, recombination, host-switching events, and a broad host range. Detection of papillomavirus infection in Roborovski hamsters for the first time sheds light on the spread of animal PVs and the need for further research into this area.

Summary: This study is the first to report the infection of E. bieneusi in golden hamsters and Siberian hamsters worldwide. The identification of four genotypes belonging to Group 1 suggests that pet hamsters, especially golden hamsters, can be potential sources of human microsporidiosis.

Summary: Seasonally breeding animals rely on environmental cues to determine optimal conditions for reproduction. Siberian hamsters primarily use photoperiod as a predictive cue. Hamsters that experienced food restriction during development showed increased sensitivity to food restriction as adults and exhibited reproductive responses.

Summary: The gut microbiome interacts with physiological systems to affect behavior and can be influenced by maternal stress and microbiomes. Maternal stress and microbiome alterations have sex-specific effects on offspring development and behavior. The maternal microbiome plays an important role in mediating offspring development and behavior.

Summary: Research on animal personality suggests that behaviors associated with social interactions may be less stable across development stages, while behaviors related to stress or coping mechanisms may show higher repeatability. Sex differences were observed in the long-term repeatability of escape behaviors, with males displaying higher consistency compared to females. Understanding how ontogeny affects animal personality can provide insights into the evolution and maintenance mechanisms of individual behavior traits.

Summary: The study investigated the physiological reactions of hamsters to chemical signals from potential sexual partners, finding that females showed an increase in blood cortisol levels while males preferred to spend time near samples of estrous females with elevated cortisol in urine. Olfactory signals also had an impact on the immune system response, with a greater increase in blood peroxidase activity observed in preferred coupling.

Summary: To survive the Siberian winter, Djungarian hamsters adjust their behavior, morphology, and physiology, with changes in body mass, fur insulation, and expression of spontaneous daily torpor. These adaptations are triggered by decreased photoperiod anticipation of winter. Torpor expression and adaptation extent are highly individual. The study reveals insights into preconditions and proximate stimuli of torpor regulation, improving experimental planning for neuroendocrine and molecular research.

Summary: Small mammals exhibit seasonal changes in intestinal morphology and function to increase energy yield from food during winter, with adjustments in small intestine histology and physiology in response to energetic challenges. Hamsters show energy-saving adjustments in short photoperiod, with longer small intestines and higher glucose transport capacities. Acute energetic challenges caused stronger increase of glucose transport capacity, while fasting-induced torpor and spontaneous daily torpor did not clearly correlate with mucosal glucose transport capacity.

Summary: Proper housing conditions are crucial for animal welfare. This study examined the effects of a running wheel, nesting material availability, and pair housing on the basal metabolic rate (BMR) of Siberian hamsters. The results showed that access to a running wheel increased BMR and body mass, while nesting material and pair housing had no effect on BMR.

Summary: This study investigates the optimal parameters for producing high-quality SFRO, including temperature and time of roasting, to obtain the highest oil extraction yield and nutrient contents. The findings provide valuable references for achieving SFRO with desirable physicochemical properties, optimal fatty acid profile, key aroma compounds, and relatively-low BaP concentration.

Summary: Breeding programs for horticultural tree crops mainly focus on improving productivity, pest and disease resistance, and crop quality. Pollination by different parents can affect almond kernel size and nutritional quality. Self-compatible cultivars may have a high percentage of kernels resulting from self-pollination, while different cross-pollen parents do not greatly impact kernel size or quality.

Summary: This study investigated the response of a local fenugreek cultivar to lead and cadmium contamination. The results showed that fenugreek was more sensitive to cadmium, and both cadmium and lead supply led to a gradual decrease in fenugreek growth. Fenugreek showed relative tolerance to excess lead and was able to maintain stable water status. At high cadmium concentration, photosynthesis and chlorophyll content in fenugreek decreased significantly. Fenugreek accumulated cadmium and translocated it to the harvestable parts, while lead was mainly accumulated in roots.

Summary: The study found that zebra finches can decrease metabolic rate to improve the efficiency of evaporative heat loss in response to heat and water restriction. Temperature acclimation and water availability did not affect the partitioning of evaporative heat loss, but the contribution of cutaneous evaporative heat loss varied at different temperatures. The consistent individual differences in metabolic rate and evaporative heat loss suggest that these traits may be subject to natural selection.

Summary: The study found that individuals born later in the season had faster growth rates and larger sizes than those born earlier, but these differences disappeared before the transition to short photoperiod. Prolonged exposure to long photoperiod inhibited winter molting, and there were significant phenotype differences among littermates. Additionally, a small percentage of individuals showed a late response to short photoperiod.

Additionally, even a low concentration of Pinnularia borealis was sufficient to improve antioxidant capacity.

Summary: Migratory birds exhibit different behaviors in thermoregulation while stopping over in the Negev desert, with Willow Warblers being the most efficient in lowering body temperature. Differences in cutaneous water loss and panting onset temperature may contribute to the evolution of different stopover strategies in migratory species crossing arid areas such as deserts.

Summary: Anthropogenic land use changes have reduced natural roost sites for European bats. Artificial roosts, such as bat boxes, are commonly used for conservation, but concerns exist regarding their heat trapping effect. This study investigates the cooling efficiency and heat tolerance differences between sexes in European bats. The results show that there are sex differences in heat dissipation strategies, possibly due to ecological and physiological constraints associated with different roosting habits.

Summary: This study investigated the effects of water and energy shortages on torpor in Siberian hamsters. The results showed that torpor frequency was lower but bouts were longer and deeper during water deprivation compared to food deprivation or both food and water deprivation. This suggests that water and energy shortages present different physiological challenges, with water deprivation leading to greater energy and water savings. The study also found that the patterns of torpor expression varied among deprivation types. These findings highlight the distinct roles of water and energy conservation in torpor.
