Abstract

This study describes the spatial and temporal distribution of density and biomass, feeding ecology and contamination by microplastics (MPs) in A. clupeoides and C. edentulus in the Goiana Estuary. A. clupeoides were found in all portions of the estuary, mainly in the late rainy and late dry seasons. C. edentulus was found in the upper and lower portions of the estuary mainly in the late dry season. A. clupeoides' adult specimens fed mainly on copepods in the lower estuary during the beginning of the rainy season when they were contaminated by black MPs. A. flexuosa larvae were consumed by subadults in the lower portion during the final rainy season and by juveniles in the lower portion during the end of the dry season when they were contaminated by the same type and color of MPs. The species C. edentulus both adults and subadults feed on Coscinodiscus sp. and Actinopthycus sp. in the lower portion during the final rainy season. At this time, adults were contaminated by blue MPs. MPs' samples were analyzed by FTIR, were composed of polyethylene..

西南大西洋热带河口生态系统浮游食性鱼类的摄食生态和微塑料污染。

本文研究了果阿纳河口（Goiana Estuary）黄颡鱼（A. clupeides）和齿形黄颡鱼（C. edentulus）的密度、生物量、取食生态和微塑料污染的时空分布特征。在河口各部位均有发现，主要集中在晚雨季和晚旱季。在河口上游和下游主要分布于干季后期。雨季开始时，成虫主要以河口下游的桡足类为食，受到黑色MPs的污染。a . flexuosa幼虫被亚成体在较低的部分在最后的雨季和青少年在较低的部分在旱季结束时受到议员的相同类型和颜色。在最后的雨季，成年和亚成虫在下部以Coscinodiscus sp.和Actinopthycus sp.为食。这个时候，成年人被蓝色的MPs污染了。用FTIR对MPs样品进行分析，MPs样品由聚乙烯组成。

期刊介绍： The Brazilian Academy of Sciences (BAS) publishes its journal, Annals of the Brazilian Academy of Sciences (AABC, in its Brazilianportuguese acronym ), every 3 months, being the oldest journal in Brazil with conkinuous distribukion, daking back to 1929. This scienkihic journal aims to publish the advances in scienkihic research from both Brazilian and foreigner scienkists, who work in the main research centers in the whole world, always looking for excellence. Essenkially a mulkidisciplinary journal, the AABC cover, with both reviews and original researches, the diverse areas represented in the Academy, such as Biology, Physics, Biomedical Sciences, Chemistry, Agrarian Sciences, Engineering, Mathemakics, Social, Health and Earth Sciences.
