The 6 % values of the animals were comparedto those of the submerged vegetation, detritus and sediment of each locality. The range of 6 13Cvalues of -7.2 to -24.20/00 indicates that consumers take advantage of sources of organic carbonof a diverse isotopic nature. The isotopic differencebehveen the lager consumers, P. setiferus, P.drrorarum, X. kroyeri, C. sapidus and D. teTc1nus, and the primaty producers indicates that thefirst occupy a high trophic leve1 within their communities. There is a relationship between themigration of P. setifems juveniles from the northeast (CTL = 11.5 mm) to íhe southwest(CTL = 22.5 mm) of the lagoon, and the variation in isotopic composition from heavier (-8.90/00)to lighter (-24.20/00) 6 13C values. Three cases are presented to explain the variety of 6 13Cvalues of P. setifenrs. In general, the isotopic composition of the above-mentioned speciescharacterized two isotopically different areas: one to the northeast of the system with heaviervalues of -6.4 to -17.20/00 and another to the west, southwest and South with lighter values of-15.3 to -24.20/00. 1993 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48019208 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.2 Vol.19 |
