Summary: Behavioural ageing patterns vary among individuals and can predict changes in behavioural repeatability. Age-related alterations in behavioural repeatability can stem from changes in within-individual behavioural variation. This study of male water striders found that mating attempts decline with age, and both among- and within-individual behavioural variation contribute to age-related changes in repeatability.

Summary: The study found that variation in MP ingestion rates in early life stages of marine fish can affect responses to MP exposure at different treatment levels, indicating individual-level effects. High MP ingestion rates led to inferior escape responses, highlighting the importance of considering individual variation in environmental exposure experiments.

Summary: Environmental stressors can have sublethal consequences for animals, affecting phenotypic traits in populations and increasing inter-individual variability. In bees, stressors decrease mean cognitive performance but increase cognitive variability. Chronic exposure has a greater impact on mean performance, but both chronic and acute exposure increase cognitive variability. Guidelines for plant protection products may overlook the consequences of chronic exposure, leading to harmful effects on bee populations. More research is needed to understand stress-induced phenotypic variation and incorporate it into policy guidelines for animal exposure.

Summary: This study investigates the effects of early shearing on Australian Merino ewes and their lambs. The results show that early shorn ewes grazed more and maintained better body condition compared to once shorn ewes, with lower levels of wool cortisol. DNA methylation analysis reveals that both shearing frequency and pregnancy status have an impact on the genomic modifications in the sheep. This research provides valuable insights into how Merino ewes respond to shearing and can guide further studies on sheep breeding and welfare.

Summary: In this study, a niche modelling approach was used to simulate the most conducive habitat for Batrachochytrium dendrobatidis (Bd) in Sri Lanka. The overlap between 69 amphibian species and the high-risk area of Bd was calculated, and a risk index was developed to identify the species most at risk. The high elevations of Sri Lanka were found to be highly conducive for Bd, and Minervarya greenii was identified as the species most at risk.

Summary: Healthy adult horses can regulate their body temperature in the thermoneutral zone, but under certain conditions, such as strenuous exercise in hot or humid environments, heat stress can occur. This can lead to serious health issues in horses, requiring early detection and intervention to reduce body temperature. Various methods, such as rectal temperature measurement and new technologies like thermal sensing microchips or infrared thermometry, are being studied for monitoring horse body temperature. Cooling methods, such as water application or air movement, are also used to alleviate heat stress and improve horse welfare.

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: According to life-history theory, there might be different immunological strategies between reproductive and non-reproductive periods due to limited resources. Our study on two sympatric marine fish species, rockfish and sandperch, found that reproductive individuals showed lower immune function, but higher levels of natural antibodies in rockfish females, compared to their non-reproductive counterparts. On the other hand, reproductively active sandperch males showed lower levels of natural antibodies and higher neutrophil to lymphocyte ratio and spleen index compared to non-reproductive males. The study highlights the species-specific patterns of immunity and the potential influence of resource limitation and abiotic factors on immune trade-offs in fish.

The researchers investigated the cholinergic and adrenergic receptor mediated control of arterial blood pressure and heart rate in the neotropic cormorant. The findings suggest that both cholinergic and adrenergic tone play a role in cardiovascular regulation in embryonic birds.

Summary: This study cloned the genes encoding glucokinase and glucose-6-phosphatase catalytic subunit in largemouth bass, revealing their distribution and transcriptional regulation. The results showed that the functions of G6pc and Gck in LMB were highly conserved in evolution, and the interconversion of glucose and G6P in the liver was well regulated at the transcript level under high starch diet, but a futile cycle was induced after a glucose load.
