Distribution and abundance of Melanoides tuberculata (Gastropoda: Thiaridae) in the Biosphere reserve of Pantanos de Centla, Tabasco, Mexico
We studied the distribution and abundance of Melanoides tuberculata in the Centla Swamps Biosphere Reserve. We sampled 19 lagoons, during the rainy (September - October 2003) dry (April - May 2004) seasons. We used the variance: Morisita’s Index (I?) and the k parameter to estimate the distribution...

| description | We studied the distribution and abundance of Melanoides tuberculata in the Centla Swamps Biosphere Reserve. We sampled 19 lagoons, during the rainy (September - October 2003) dry (April - May 2004) seasons. We used the variance: Morisita’s Index (I?) and the k parameter to estimate the distribution pattern space aggregation index. We registered the species 18 lagoons. A total of 13,597 individuals were collected, the greater abundance appeared during the rainy season (8,364 individuals). All populations presented an aggregated spatial distribution pattern. Abundance was inversely correlated with chemical oxygen demand and directly correlated with nitrates during the rainy season. During the dry season, abundance was inversely correlated with salinity and directly with nitrates, nitrites and pH. |

Se estudió la distribución y abundancia de Melanoides tuberculata en la Reserva de la Biosfera Pantanos de Centla. Los muestreos se realizaron en 19 lagunas distribuidas en el interior de la Reserva durante la época de lluvias (septiembre y octubre 2003) y en la época de estiaje (abril y mayo 2004). Para conocer el patrón de distribución espacial se utilizaron índices de agregación: Índice de Morisita (I?) y Parámetro k. Se encontró la presencia de esta especie en 18 de las lagunas muestreadas. Se recolectaron 13,597 individuos. La mayor abundancia se presentó en la época de lluvias (8,364 individuos). Las poblaciones en cada laguna presentaron un patrón de distribución espacial agregado. Durante la época de lluvias se encontró una correlación inversa entre la abundancia y demanda química de oxígeno y directa con nitratos, y en la de estiaje inversa entre la abundancia y salinidad y directa con nitratos, nitritos y potencial de hidrógeno.
