Resumo: |
The present study aimed to analyze zooplankton with emphasis on the occurrence of burrowing shrimp larvae between more coastal waters and waters of an estuarine plume, during drought (dry) and rainfall events and between environmental parameters (temperature, pH and salinity) and relate to the occurrence of ovigerous females. For this, a manuscript was produced in which the study area comprised a marine-estuarine system, located between the municipalities of Paulista and Igarassu, north coast of Pernambuco. Taking the estuarine plume of the Timbó river as a reference, zooplankton samples were collected at three sampling stations: 1-estuarine plume, 2- waters from the northern portion in relation to the plume and 3- waters from the southern portion. The environmental variables of the water in each station were also measured. Adult individuals were collected at Mangue Seco beach, adjacent to the plume. Organisms were identified and quantified. A PERMANOVA test was applied to verify the occurrence of significant differences between larval density, collection stations and sampling events. Among the taxa found in zooplankton, Axianassa australis, Upogebia sp., Callichirus corruptus, Lepidophithalmus siriboia and Neocallichirus sp. were identified. it was not possible to identify significant differences in larval density and observed factors. Larvae of the species Axianassa australis were the most representative throughout the study, thus demonstrating that burrowing shrimp of estuarine origin contribute more to the coastal zooplankton community. There was coincidence between the occurrences of larval species and ovigerous females. However, the adult individual of A. australis was not collected, suggesting that the absence of adults is caused by environmental incompatibility. Thus, the study provides information relevant to the ecology and larval contribution of burrowing shrimp in the natural environment. |
