Summary: This study investigated the transcriptional regulation of estrogen receptors (ESRs) on isotocin receptors (itrs) in guppies, and found that estrogen can regulate oxytocin receptor expression in ovoviviparous teleosts. The study also demonstrated that ESR1 represses itr2 promoter activity in an estrogen-dependent manner, while overexpression of ESR2a or ESR2b enhances itr2 promoter activity.

Summary: This study reveals that exposure to VPA induces ASD-like phenotypes and behaviors, including gene transcription changes, social interaction deficit, decreased aggression, increased anxiety behavior, and elevated cortisol levels. The aggression behavior assay is a better predictor of neurotoxicology behavior of VPA.

Summary: rNLRC3 negatively regulates the NF -KB signaling pathway induced by P. multocida in rabbits by inhibiting the activation of NF -KB, reducing the expression of inflammatory cytokines, and interacting with rTRAF4 and rTRAF6. The NACHT-LRR domain is the functional domain of rNLRC3. These findings provide insights into the important role of rNLRC3 in combating P. multocida infection.

Summary: Environmental factors can cause cancer in both wild animals and humans. The use of polluted habitats provides opportunities to study cancer defense mechanisms, which can be influenced by genetic variation and natural selection. Flatfish species, specifically flounders, show higher resistance to pollution-induced cancer compared to dabs, with elevated pollutant metabolism and stronger tumor suppression mechanisms in their liver tissue. This suggests a potential hormetic upregulation of tumor suppression or stronger natural selection pressure for cancer resistance in flounders. Wild species offer valuable insights into understanding the nature and evolution of natural cancer defense mechanisms.

Summary: Winner and loser effects are observed in many animals, and recent experiments suggest that they may also occur in humans. In two experiments involving video games and reading comprehension, participants who won in the first phase performed significantly better in the second phase compared to those who lost. The effect size was larger in the video game experiment, and men and women showed similar magnitudes of winner and loser effects.

Summary: The study focuses on the expression patterns of PFK genes in response to glucose, insulin, and glucagon stimuli in grass carp. The findings suggest that PFK family genes have different or even opposite expression patterns in various tissues, which may contribute to glucose intolerance in fish.

Summary: This study investigated the osmotic stability and cellular responses of hemocytes in Mediterranean mussel and Pacific oyster. The results revealed that both species showed cellular volume changes and alterations in mitochondrial membrane potential upon hypoosmotic swelling. These findings provide insights into the cellular responses of bivalve mollusks to osmotic stress.

Summary: Environmental conditions, particularly temperature, have a significant impact on animal behavior. This study focused on aggression in Neolamprologus pulcher fish and found that aggression rates increased with temperature at lower levels, but decreased after reaching a peak. Additionally, the influence of high temperatures on aggression changed over time during the trials. These findings provide a more comprehensive understanding of the short-term effects of temperature on aggression and highlight the importance of considering non-linear changes in thermal performance.

Summary: This study examines the trade-off between mating effort and thermoregulatory behavior in dragonflies in response to temperature changes, and investigates the effect of wing melanin on these behaviors. The results indicate that as temperature increases, dragonflies reduce their mating effort and increase their thermoregulatory behavior.

Summary: Human activities have affected the availability of resources for wildlife, particularly through the provision of anthropogenic food subsidies at landfill sites. This study explores the influence of age on landfill attendance and foraging behavior in white storks. Adult storks visit landfills more frequently and show dominance over juveniles in food acquisition. Juveniles have limited access to landfill resources and are forced to use lower quality areas.

Summary: The study explored the impact of environmentally relevant concentrations of E2 on the immune system and hormone levels of hatchling American alligators. Results showed that exposure to environmental estrogen can alter plasma hormone concentrations but have little to no impact on morphology and immune responses.

Summary: The acclimatization of certain ectothermic vertebrates to winter conditions involves reduced energy consumption, achieved through decreased movement activity, depression of cellular functions, or switching to anaerobic energy production. This study on crucian carp showed that winter-acclimatized fish exhibited lower metabolic rates and a shift to anaerobic energy production during anoxia. Winter dormancy in crucian carp is achieved through active reduction of energy consumption, a slowed metabolic rate, and a direct response to oxygen absence.

Summary: Metal pollution has significant effects on aquatic environments, and metallothioneins play important roles in maintaining metal homeostasis and detoxification. This study identified two metallothionein-coding transcripts in Gammarus fossarum and investigated their organ-specific expression patterns. The results showed that mt1 was more strongly induced after cadmium exposure, and mt1 was more highly induced in the caeca compared to the gills for any metal exposure. Additionally, mt2 was more inducible in the gills than in the caeca for cadmium and zinc exposure at the individual level.

Summary: This study investigated the influence of habitat and nest-box location on the occupation and breeding parameters of Kestrels in Central Europe. The results showed that Kestrels prefer nest-boxes hung on power poles and in areas with a lower proportion of forests. Breeding success was influenced by the proportion of grasslands and the number of individual trees. However, no environmental components were found to have an impact on Kestrels' productivity.

Summary: The diapausing embryos of invertebrates invest in future populations, thus their eggshells must be able to withstand various environmental assaults. This study examined the eggshells of rotifers and compared them to brine shrimp cysts and mosquito overwintering eggs. The results showed that while rotifer eggshells had lower Young's moduli and hardness values compared to the other species, all eggshells were relatively elastic and not particularly resistant to deformation. The pliancy of eggshells may be an adaptation to resist cracking under sediment burial. The composition of eggshells may play a role in determining elasticity and hardness.

Summary: Keystone components, such as silk-floss trees, play a crucial role in supporting animal communities in urban green spaces. A comprehensive study in suburban Guadalajara, Mexico, recorded 79 insect species, 8 bird species, and 1 mammal species visiting the flowers of a silk-floss tree. The tree not only provided floral resources but also served as habitat and feeding substrate for birds. Four of the recorded species are listed for conservation. The study highlights the importance of small patches in enhancing the quality of urban green spaces and emphasizes the role of flower output in attracting visitors.
