O objetivo do estudo foi caracterizar quatro populações de Halodule wrightii no litoral norte de Alagoas, nordeste brasileiro. Entre novembro de 2011 e janeiro de 2012 foram coletadas 12 amostras por praia, sendo quatro por mancha, sempre se evitando as bordas. Em laboratório foram determinadas a densidade, a biomassa, o comprimento e a largura de folhas, com as diferenças entre os pontos de coleta analisadas pelo teste t e ANOVA one-way. Constatou-se diferenças significativas nas características morfológicas entre as populações, sendo as plantas de Barra Grande as maiores e de Tatuamunha as mais largas. As densidades entre as praias não apresentaram diferenças significativas, contudo as plantas de Porto da Rua revelaram diferença significativa intrapopulacional. Foi confirmada a plasticidade morfológica dentro e entre as populações de H. wrightii sendo sugeridos novos estudos que incluam diferentes variáveis ambientais de qualidade de água.Referências
