Effects of early resource-limiting conditions on patterns of growth, growth efficiency, and immune function at emergence in a damselfly (Odonata: Coenagrionidae)

摘要: Periods of restricted growth during early development are expected to have detrimental effects on subsequent metrics fitness, most prominently increases in age and decreases size at maturity. However, some cases, animals may compensate by altering foraging effort, efficiency, or patterns resource allocation between critical traits prior maturation. Yet, even when compensation for is complete, brief periods carry costs persisting the long term, compensatory tactics themselves be costly. We investigated long-term restriction mechanisms damselfly Ischnura verticalis (Say, 1839). Larvae were temporarily exposed one three feeding regimes stages development, after which food levels restored. In period unrestricted emergence, partial structural lowest treatment was observed, while both resource-limite...
