Dalila Aldana Aranda José Francisco Chávez Villegas Manuel Sánchez Crespo Biología Allee effect Sandy effect Strombus gigas reproductive behavior The marine park of Xel-Há has a population of Strombus gigas which breeds in the area. We deter - mined the relationship between reproductive activity , conch density and environmental parameters. Samples were collected from February to December 2012, using the transect method, at four sites of Marine Park Xel-Ha, Quintana Roo, Mexico. Sediment samples were analyzed and classified using Folk & Ward’s method. Temperature, salinity and dissolved oxygen were also recorded. Density had a small correlation with sediment (Pearson r=0.29 with very coarse and r=0.26 with coarse sand), while mating and spawning had a correlation of r=0.54 and 0.62 with medium sand, respectively. Density was high in the four sites and was not associated with mating and spawning (r=0.08 and 0.03, respectively). For reproduction, S. gigas requires specific substrate conditions ( sandy effect ) and not just a density of 56 Conch Ha –1 (A llee effect ). 2014 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44932432019 en http://www.redalyc.org/revista.oa?id=449 Revista de Biología Tropical application/pdf Universidad de Costa Rica Revista de Biología Tropical (Costa Rica) Num.3 Vol.62 |
