“…In the urban park site, many trees were exotic species, which are known to reduce abundance and diversity of arthropods 39 , particularly lepidopteran larvae 40, 41 . Negative effects could be exacerbated by fragmentation and disturbance of lepidopterans, which may also play a role in regulating healthy population sizes 42 . The detected differences in caterpillar availability are expected to influence dietary provisioning, which largely depend on the immediate surrounding environment 31 .…”

Animals often show reduced reproductive success in urban compared to adjacent natural areas. The lower availability and quality of natural food in cities is suggested as one key limiting factor. However, only few studies have provided conclusive support by simultaneously assessing food availability, diet and fitness. We consolidate this evidence by taking a holistic approach, comparing blue tits breeding in forest, suburban and urban areas. We (a) assessed arthropod availability, (b) investigated parental provisioning behaviour, (c) inferred diet through stable isotope analysis, and (d) measured reproductive success. At the urban site, we found a significant reduction in caterpillar availability, the main food source of blue tits, and consequently urban tits fed their offspring with fewer caterpillars than forest and suburban birds. Stable isotope analysis confirmed that diet in the urban area was fundamentally different than in the other sites. Reproductive success was lower in both urban and suburban sites compared to the forest site, and was positively associated with volume of provisioned caterpillars. Our findings provide strong integrative evidence that urban blue tit nestlings are not receiving a suitable diet, and this may be an important limiting factor for urban populations of this and potentially many other species.

“…It has been shown that PA and DG, which are found in quantities Ͻ20 pmol/10 6 cells in most cell types, play important roles in cellular signaling (2)(3)(4). PA species have been implicated in mitogenesis, cellular transformation, and exocytic processes (5,6), as well as inflammatory signaling by interleukin-1 (IL-1) (7).…”

Die Biosynthese der für den Menschen bedeutenden Eicosanoide ist von der Konzentration der Ausgangssubstanz, Arachidonsäure, sowie vom Vorhandensein von Inhibitoren, wie der Eicosapentaensäure, abhängig. Eine Hemmung der Eicosanoidbildung durch Fischölfettsäuren ist umso wirksamer, je weniger Arachidonsäure in den Zellen vorhanden ist. Die Konzentration der Arachidonsäure ist von der Umwandlungsrate der Linolsäure und der Zufuhr anderer mehrfach ungesättigter Fettsäuren abhängig, für die eine Kompetition im Stoffwechsel beschrieben ist. Entsprechende diätetische Maßnahmen Können die Eicosanoidbiosynthese manipulieren, wodurch zahlreich Erkrankungen behandelt werden können. Eine gesteigerte Biosynthese der Eicosanoide konnte für die Arteriosklerose, allergische und neoplastische Erkrankungen, die Colitis ulcerosa, den Morbus Crohn, die Psoriasis und entzündliche Gelenkerkrankungen nachgewiesen werden. Eine Ernährung, die auf eine Verminderung der Eicosanoidbiosynthese ausgerichtet ist, kann den Verlauf dieser Krankheiten bessern. Ernährungstherapeutische Maßnahmen sind eine ausreichend hohe Zufuhr an Linolsäure, die Verminderung der Arachidonsäure und die Einbeziehung langkettiger n‐3‐Fettsäuren in die Kost.
