Summary: Understanding the mechanisms of individual organisms and populations to adapt to global climate change is crucial. This study investigated the plasticity across generations and life stages in response to ocean acidification in shellfish. The results showed that the negative impacts of ocean acidification can last within and across generations, but buffering against acidification at critical life-history windows can mitigate these effects.

Summary: The outcome of in vitro fertilization of P. lividus is influenced by maternal influences, but largely determined by culture conditions. Twenty-three genes involved in response to stress and skeletogenesis were differently expressed in sea urchins cultured in two experimental conditions. These findings are critical to develop protocols for the larval culture of P. lividus.

Summary: Animals respond to stimuli from their surroundings, and owls in captivity demonstrated different temperaments and glucocorticoid metabolite levels when challenged with predators. Adjectives indicating passiveness, vulnerability, and attentiveness were correlated with shyness, and owls with higher shyness scores showed higher post-predator challenge glucocorticoid metabolite levels. However, there were no significant differences in glucocorticoid metabolite levels before and after the predator challenge. This study confirms the relationship between shy temperament and adrenal response in nocturnal raptorial birds and provides non-invasive methods to assess the welfare of captive species.

Summary: This experiment investigated the effects of feeding low and high supplies of vitamin A (VA) during the transition period on plasma metabolites, prevalence of ketosis, and early milk production. The results showed that different doses of VA did not significantly affect dry matter intake, milk yield, and milk fat, protein, and lactose yields. However, excessive VA supply had a negative impact on immune response, contributing to increased milk somatic cell counts during early lactation.

Summary: Starting from Hans Selye's stress physiology, researchers have been investigating the physiological mechanisms linking stress to health and disease. They have focused on the link between psychological stress and cardiovascular disease (CVD), the leading cause of death in the United States. Studies have shown that psychological stress is an independent risk factor for CVD, and it can lead to increased systemic inflammation, contributing to CVD development. Physical activity has been found to buffer against the harmful effects of psychological stress by strengthening stress response systems and immune system, reducing stress-induced inflammation, and attenuating mechanisms associated with CVD development. Additionally, the COVID-19 pandemic has provided a model for understanding the stress-health relationship.

Summary: In recent years, there has been a growing concern about milk pollution by aflatoxin M1 due to the increasing prevalence of aflatoxins in animal feeding and dairy product consumption. A study was conducted to determine the transfer of aflatoxin B1 into milk and its effects on production and serological parameters in goats. Goats were exposed to different doses of aflatoxin B1 for 31 days and the concentration of aflatoxin M1 in milk was found to significantly increase with the amount of aflatoxin B1 ingested. However, the ingested amount did not affect the aflatoxin M1 carryover, indicating a certain resistance of goats to the effects of aflatoxin B1.

Summary: This paper explores the importance of adaptive changes for survival and the critical role of energetic resource regulation. It discusses the physiological changes accompanying stress and their relationship with loss of confidence in a system's predictions, leading to depressive symptoms. By identifying the hierarchical controllers of energy resources, an etiological pathway from allostatic overload to depression is established.

Summary: The study found that long-term exposure to ocean acidification negatively affects adult individuals of the slipper limpets, but offspring show higher adaptability and growth rates. Long-term exposure may have persistent effects on reproductive output, while the presence of transgenerational effects suggests that slipper limpets have the potential to adapt to rapid acidification.

Summary: This study examines the physiological mechanisms of facultative movements in the pine siskin. The results suggest that the siskin's migration behavior is neither fully prepared nor purely based on escape from resource-poor areas. Rather, it is influenced by factors such as food intake and body condition.

Summary: Sharks, including blue sharks, exhibit exaggerated physiological responses to capture and handling stress. The study found that blue sharks in recreational fishing can withstand capture and handling in a catch-and-release setting without experiencing blood acidosis. However, smaller individuals may be more susceptible to capture stress. The findings have implications for angler education in the recreational fishery.

Summary: Dehooking tools and bare hands were compared for their efficacy in removing hooks from Bluegill fish caught with barbed and barbless hooks. Bare hands took the longest time, while there was little difference in dehooking times among the tools used. However, using tools resulted in more tissue tearing compared to bare hands. Barbed hooks took significantly longer to remove than barbless hooks, and there was an increase in tissue tear size for fish caught on barbed hooks. Larger fish took longer to dehook, but tearing was not size-dependent. Bleeding incidence was low and not significantly different among treatments. Reflex impairment was observed only in fish caught on barbed hooks with longer dehooking times. Overall, using barbless hooks is more important than the specific dehooking tool used.

Summary: This study investigated the potential effects of red tide events on Atlantic tarpon along the southwestern coast of Florida. The results showed that tarpon are somewhat tolerant to red tide blooms, but when the blooms overlap with tarpon peak abundance and become dense and large, tarpon may leave the affected area or suffer mortality. Additionally, the study found an increase in the overlap of red tide blooms with tarpon spawning season. Combining multiple data sources helped elucidate how red tide exposure influences tarpon and the recreational fishery that targets them.

Summary: The spatial ecology of common carp within Lake Ontario was studied using passive acoustic telemetry across multiple spatial scales. The study found that season and physical habitat conditions significantly affected the habitat preference of common carp, with higher preference for sites with increased submerged aquatic vegetation during spring and summer. Larger individuals were more likely to be absent from the array during summer. Non-resident common carp exhibited extensive movements along the nearshore of Lake Ontario during spring and summer and were detected throughout the entire basin.

Summary: The common carp is a non-native fish species that negatively impacts freshwater environments. Conventional management focuses on using barriers to control or contain the carp, but the impacts on native species should also be considered. Different biological traits, such as phenology, sensory ability, morphology, and behavior, can be exploited to design barriers that minimize the ecological impacts on native species.

Summary: During spawning migrations, adult Pacific salmon must undergo changes in gene expression and behavior to adapt to stressful conditions. Assessments of physiology and infectious agent presence in gill tissue can provide insights into these adaptations. The study found that migrating salmon exhibited decreased thermal stress gene expression and showed evidence of cooler water selection, suggesting behavioral changes and potential benefits of thermal refuges in reducing the negative impacts of infection.

Summary: Freshwater habitats are facing biodiversity loss at a rate two to three times higher than terrestrial and marine habitats. In order to reverse this trend, we propose four actions to increase the recognition, value, and protection of freshwater biodiversity: reshaping our relationship with freshwater habitats, appreciating indigenous knowledge, linking science and action more directly, and elevating the importance of freshwater habitats in conservation planning (RACE). Both freshwater scientists and the wider conservation community have key roles to play in implementing these actions and ultimately winning the RACE.

Summary: Atlantic tarpon (Megalops atlanticus) supports an economically important fishery, but there is limited information on their fishery and population. A survey of anglers and fishing guides was conducted to address data deficiencies and understand the status and threats to Atlantic tarpon. The survey revealed a decline in fishing quality since the 1970s, with water and habitat quality as major threats. These findings highlight the importance of ecological knowledge from recreational anglers and fishing guides for the conservation of Atlantic tarpon populations.
