Fatty acids and their derivatives are molecules that provide energy, control inflammation and participate in body thermoregulation, and therefore changes in fatty acids affect the condition and fitness of individuals. A good quality diet is rich in physiologically essential \u03c93 fatty acids, which are needed to maintain a range of these physiological functions. Ionizing radiation is an environmental change which can directly or indirectly (through habitat changes) affect the physiology of organisms, but whose effect on fatty acids, especially in natural populations, has not been studied. The present study was conducted to investigate whether ionizing radiation has an effect on the blood plasma fatty acid profile of great tits (Parus major) in Chernobyl area. The study area was the unique Chernobyl exclusion zone, where radiation levels vary from high (30\u201357 \u03bcSv/h) to normal background levels (< 0.1 \u03bcSv/h). As a consequence of radiation, poorer dietary quality and direct stress expected to reduce the amount of \u03c93 fatty acids and increase the proportion of oleic acid in blood plasma. To achieve these objectives, blood plasma samples of great tits and their nestlings were collected from different radiation areas, and processed in the laboratory to extract fatty acids, after which the concentrations and relative proportions of fatty acids in blood plasma were determined. The study found that ionizing radiation increased the levels of oleic acid and decreased the amounts of long-chained \u03c93 fatty acids in nestling plasma but had no effect on the proportions of short-chained \u03c93 fatty acids. On the other hand, the irradiation did not cause significant changes in adult fatty acids. However, changes in the fatty acid profile of the nestlings suggest that ionizing radiation may affect the diet or fatty acid synthesis of great tit nestlings, which may alter body condition and fitness of the individuals.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2024-03-28T07:28:02Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2024-03-28T07:28:02Z (GMT).
