Warm acclimation alters antioxidant defences but not metabolic capacities in the Antarctic fish, Notothenia coriiceps
<p>The Southern Ocean surrounding the Western Antarctic Peninsula region is rapidly warming. Survival of members of the dominant suborder of Antarctic fishes, the Notothenioidei, will likely require thermal plasticity and adaptive capacity in key traits delimiting thermal tolerance. Herein, we have assessed the thermal plasticity of several cellular and biochemical pathways, many of which are known to be associated with thermal tolerance in notothenioids, including mitochondrial function, activities of aerobic and anaerobic enzymes, antioxidant defences,protein ubiquitination and degradation in cardiac, oxidative skeletal muscles and gill of <em>Notothenia coriiceps</em> warm acclimated to 4◦C for 22 days or 5◦C for 42 days. Levels of triacylglycerol (TAG) were measured in liver and oxidative and glycolytic skeletal muscles, and glycogen in liver and glycolytic muscle to assess changes in energy stores. Metabolic pathways displayed minimal thermal plasticity, yet antioxidant defences were lower in heart and oxidative skeletal muscles of warm-acclimated animals compared with animals held at ambient temperature. Despite higher metabolic rates at elevated temperature, energy storage depots of TAG and glycogen increase in liver and remain unchanged in muscle with warm acclimation. Overall, our studies reveal that <em>N. coriiceps</em> displays thermal plasticity in some key traits thatmay contribute to their survival as the Southern Ocean continues to warm.</p>

Data for: Innate immune function and antioxidant capacity of nestlings of an African raptor co-vary with the level of urbanization around breeding territories
<p>Urban areas provide breeding habitats for many species. However, animals raised in urban environments face challenges such as altered food availability and quality, pollution, and pathogens assemblages. These challenges can affect physiological processes like immune function and antioxidant defences which are important for fitness.</p> <p>Here, we explore how levels of urbanisation influence innate immune function, immune response to a mimicked bacterial infection and antioxidant capacity of nestling Black Sparrowhawks <em>Accipiter melanoleucus</em> in South Africa. We also explore the effect of timing of breeding and rainfall on physiology since both can influence the environmental condition under which nestlings are raised. Finally, because urbanisation can influence immune function indirectly, we use path analyses to explore direct and indirect associations between urbanisation, immune function, and oxidative stress.</p> <p>We obtained measures of innate immunity (haptoglobin, lysis, agglutination and bactericidal capacity), indices of antioxidant capacity (total non-enzymatic antioxidant capacity (tAOX), and total glutathione from nestlings from 2015 - 2019. In addition, in 2018 and 2019, we mimicked a bacterial infection by injecting nestlings with lipopolysaccharide and quantified their immune response.</p> <p>Increased urban cover was associated with an increase in lysis and a decrease in tAOX, but not with any of the other physiological parameters. Furthermore, except for agglutination, no physiological parameters were associated with the timing of breeding. Lysis and bactericidal capacity, however, varied consistently with the annual rainfall pattern. Immune response to a mimicked a bacterial infection decreased with urban cover but not with the timing of breeding nor rainfall. Our path analyses suggested indirect associations between urban cover and some immune indices via tAOX but not via the timing of breeding.</p> <p>Our results show that early-life development in an urban environment is associated with variation in immune and antioxidant functions. The direct association between urbanisation and antioxidant capacity and their impact on immune function is likely an important factor mediating the impact of urbanisation on urban-dwelling animals. Future studies should explore how these results are linked to fitness and whether the responses are adaptive for urban-dwelling species.</p>

Data from: Lactation and resource limitation affect stress responses, thyroid hormones, immune function and antioxidant capacity of sea otters (Enhydra lutris)
1. Lactation is the most energetically demanding stage of reproduction in female mammals. Increased energetic allocation toward current reproduction may result in fitness costs, though the mechanisms underlying these trade-offs are not well understood. Trade-offs during lactation may include reduced energetic allocation to cellular maintenance, immune response and survival, and may be influenced by resource limitation. 2. As the smallest marine mammal, sea otters (Enhydra lutris) have the highest mass-specific metabolic rate necessitating substantial energetic requirements for survival. To provide the increased energy needed for lactation, female sea otters significantly increase foraging effort, especially during late-lactation. Caloric insufficiency during lactation is reflected in the high numbers of maternal deaths due to End-Lactation Syndrome in the California subpopulation. 3. We investigated the effects of lactation and resource limitation on maternal stress responses, metabolic regulation, immune function and antioxidant capacity in two subspecies of wild sea otters (northern: E. l. nereis and southern: E. l. kenyoni) within the California, Washington and Alaska subpopulations. 4. Lactation and resource limitation were associated with reduced glucocorticoid responses to acute capture stress. Corticosterone release was lower in lactating otters. Cortisol release was lower under resource limitation and suppression during lactation was only evident under resource limitation. Lactation and resource limitation were associated with alterations in thyroid hormones. Immune responses and total antioxidant capacity were not reduced by lactation or resource limitation. Southern sea otters exhibited higher concentrations of antioxidants, immunoglobulins and thyroid hormones than northern sea otters. 5. These data provide evidence for allocation trade-offs during reproduction and in response to nutrient limitation but suggest self-maintenance of immune function and antioxidant defenses despite energetic constraints. Income-breeding strategists may be especially vulnerable to the consequences of stress and modulation of thyroid function when food resources are insufficient to support successful reproduction and may come at a cost to survival, and thereby influence population trends.
Effect of dietary Chlorella vulgaris and carbohydrate-active enzymes on the general health, immune status, antioxidant capacity, and liver lipids and metabolites of weaned piglets
<p>It was evaluated the impact of dietary inclusion of <em>Chlorella vulgaris </em>(CH) and carbohydrases on the general health, immune and oxidative status, and hepatic lipids and metabolites of piglets. Forty-four male weaned piglets were allocated into four diets: control (<em>n</em>=11), CH (control diet with 5% CH, <em>n</em>=10), CH+R (control diet with 5% CH plus 0.005% Rovabio<sup>®</sup>Excel AP, <em>n</em>=10), and CH+M (control diet with 5% CH plus 0.01% of a pre-selected four-CAZyme mixture, <em>n</em>=11) for 15 days. Total cholesterol, LDL-cholesterol and VLDL-cholesterol were increased by CH. In piglets fed CH<em>-</em>based diets, the interplay observed between IgG increase and IgM decrease contributed for piglets’ survival during weaning. <em>n</em>-6 PUFA were lower in piglets fed CH with or without feed enzymes and the inverse occurred for <em>n</em>-3 PUFA, thus benefiting <em>n</em>-6/<em>n</em>-3 ratio in the liver. The discriminant analysis applied to hepatic variables revealed a good separation between control and CH-based diets but failed to discriminate feed enzymes addition. Minor variations were promoted by Rovabio or the pre-selected enzymatic mixture, thus suggesting some improvement on microalga nutrients digestibility. Taken together, our findings indicate a health promoting effect of CH as feed ingredient in piglets’ nutrition during the weaning period, without negatively impacting on animals’ performance.</p> <p> </p>
