Resumen:
In oviparous reptiles, lipid content in tissues of females represents energy stored in the previous months to be invested in reproduction, which would be determined by the availability of food resources in environment. Energy that is destined to yolk, in particular as fatty acid (FA), and represents most of the investment maternal to the successful development of embryo. Yolk FA composition would be influenced by two main factors: maternal diet (particularly essential FA (C18:2, C18:3, C20:4) that animals cannot produce) and genetic (which regulates metabolic factors). The aim of this study was to assess effect of maternal tissue FA on egg FA composition of Caiman latirostris in two consecutive breeding seasons (2013-14 and 2014-15). We captured eight wild females of C. latirostris (4 each breeding season) in Santa Fe province. We extracted a sample of caudal muscle tissue (size 5-10g) and collected five fertile eggs of each clutch (with development
