Guzmán del Próo Jorge Carrillo Laguna Raúl Herrera Fragoso Jorge Belmar Pérez Ciencias de la Tierra kelp El Niño abalone recruitment spiny lobster An evaluation of the effects of El Niño (1997-98) on the recruitment of benthic invertebrates (abalone, spiny lobster, andkelp beds) was carried out in two reefs at Bahía Tortugas on the central Pacific coast of Baja California. Density changes ofjuvenile abalone (Haliotis fulgens and H. corrugata), kelp (Macrocystis pyrifera and Eisenia arborea), and puerulus settlement ofspiny lobster (Panulirus interruptus), before and throughout El Niño, were used to measure the impact on the recruitment ofbenthic populations of the rocky sublittoral.El Niño had a different effect on each species. Kelp beds were eliminated at an early stage in fall 1997, but recoveredpartially one year later and fully by winter 1999. Density of one-year-old abalone was reduced drastically in fall 1997. It slowlyrecovered throughout 1998 and 1999. During the latter period, this age group displayed high variability in length, suggesting anindirect effect of El Niño on the food supply of juvenile abalone. Density of puerulus spiny lobster settlement was positivelystimulated during El Niño matching, without any time lag, the increase in mean sea level and surface temperature. We concludethat benthic communities on this part of the coast show high resilience, and their populations are adapted to recovering theirstructure and normal community conditions one and a half to two years after the El Niño event. 2003 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56842314 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.42 |
