Influence of climatic conditions on the link between oxidative stress balance and landfill utilisation as a food resource by white storks. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 903:166116.

Abstract
Landfills have played a significant role in the recovery of white storks (Ciconia ciconia) populations across various European countries. While there is ample information about the populational-level effects, there is a lack of knowledge regarding the individual effects of using this food resource for feeding nestlings. This study aims to assess the nutritional status and oxidative stress balance of nestlings with varying degrees of exposure to landfill-provided food This study aims to assess the nutritional status and oxidative stress balance of nestlings with different use of landfill-provided food. Nestlings fed with food foraged by breeding pairs from landfills exhibited better nutritional status compared to individuals located farther from landfills. This can be attributed to a higher ingestion rate, resulting in increased plasmatic values of cholesterol, triglycerides, and HDL in plasma. However, the oxidative stress balance varied across different years, with individuals raised in 2014 showing higher values of Vitamin E and lower values of LDH compared to those raised in 2013. Furthermore, the impact of landfills on certain oxidative stress parameters also depended on the year of study. In 2013, the Total Antioxidant Capacity (TAC) of plasma showed a positive correlation with the distance to landfills, while the concentration of Malondialdehyde (MDA), an indicator of lipid peroxidation, exhibited a negative correlation. These findings suggest that the use of landfills as a food resource has a consistently positive effect on the nutritional status of white stork nestling. However, the relationship with oxidative stress is highly dependent on the climatic conditions of each year, emphasizing the importance of considering these factors when evaluating the use of landfills as a food resource.

Abstract
In long-lived monogamous social species, partner compatibility can play a crucial role in reproductive success. We evaluated assortative mating based on body condition (plasma triglyceride concentration), diet (δ15N), and foraging habitat (δ13C) in the blue-footed booby Sula nebouxii, a long-lived monogamous seabird. We investigated the effects of assortative mating (sum of triglycerides in a pair) and asymmetry within pairs (residuals from regression of female-male triglycerides) on reproductive performance and offspring growth (alkaline phosphatase, ALP). We found that strong assortative mating determined by body condition and diet seemed to be related to a signalling mechanism (nutritional state). This mating pattern had a substantial effect on the breeding parameters and influenced offspring ALP. Within-pair asymmetry did not influence any reproductive parameters, but the ALP of offspring was related to the within-pair relative female condition. Overall, our results indicate that individuals seek the best possible match to maximize their breeding investment and/or individuals are limited in their mate options by their current body condition, which has consequences for offspring fitness in the short term. Our findings show that assortative mating based on body condition produces notable variation in the joint condition of the pair, which determines their breeding success.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 650:1382-1391. [PMID: 30308825 DOI: 10.1016/j.scitotenv.2018.09.069] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/13/2018] [Revised: 09/05/2018] [Accepted: 09/05/2018] [Indexed: 05/04/2023]
Abstract
Some domestic waste disposal sites (DWDS) accumulate enormous amounts of food that humans discard. This food resource is exploited by different species whose population dynamics have as a result been altered. The effects of feeding on human waste on individual health parameters such as body condition are still unknown. Traditionally, body condition in wildlife has been assessed using morphological indices based on size and weight. Expanding the range of indices to include the analysis of indicators at the physiological level can provide a more comprehensive picture of the animals' health status. In this work, we studied how different amounts of waste consumption (assessed using stable isotope analysis) affect nestling health and body condition in an expanding population of the endangered Egyptian Vulture (Neophron percnopterus). We used morphometric and physiological approaches, including plasma biochemistry, antioxidant defences and oxidative stress biomarkers. The results of the multivariate redundancy analysis and variance partitioning showed that the proportion of diet originating from DWDS is the main factor explaining physiological indicators in the studied vulture population. Nestlings that were fed on food from DWDS had lower levels of vitamins (e.g. α-tocopherol) and carotenoids (zeaxanthin and lutein), which have important functions as antioxidant defences, immunostimulant properties and ornamental purposes. Nevertheless, nestlings that were fed on food from DWDS were better nourished and experienced fewer food shortages than individuals not fed using this resource, which had lower levels of cholesterol. Possibly due to the easy access to food, breeding pairs using DWDS could have fewer difficulties in feeding their nestlings and thus could engender more regular brood sizes than those not exploiting this type of resource. Our integrative approach using diverse components was crucial for a reliable assessment of health and body condition in Egyptian Vulture nestlings and its relationship to the consumption of food derived from human-altered environments.

Abstract
Individual immune responses are likely affected by genetic, physiological, and environmental determinants. We studied the determinants and short-term consequences of Phytohaemagglutinin (PHA) induced immune response, a commonly used immune challenge eliciting both innate and acquired immunity, on lesser kestrel (Falco naumanni) nestlings in semi-captivity conditions and with a homogeneous diet composition. We conducted a repeated measures analyses of a set of blood parameters (carotenoids, triglycerides, β-hydroxybutyrate, cholesterol, uric acid, urea, total proteins, and total antioxidant capacity), metabolic (resting metabolic rate), genotypic (MHC class II B heterozygosity), and biometric (body mass) variables. PHA challenge did not affect the studied physiological parameters on a short-term basis (<12 hr), except plasma concentrations of triglycerides and carotenoids, which decreased and increased, respectively. Uric acid was the only physiological parameter correlated with the PHA induced immune response (skin swelling), but the change of body mass, cholesterol, total antioxidant capacity, and triglycerides between sessions (i.e., post-pre treatment) were also positively correlated to PHA response. No relationships were detected between MHC gene heterozygosity or resting metabolic rate and PHA response. Our results indicate that PHA response in lesser kestrel nestlings growing in optimal conditions does not imply a severe energetic cost 12 hr after challenge, but is condition-dependent as a rapid mobilization of carotenoids and decrease of triglycerides is elicited on a short-term basis.
