Análise das assembléias de foraminíferos no sedimento superficial do Recife de Fora, região sul da Bahia

Abstract

Resumo O Recife de Fora é um ambiente de média a alta energia, o qual reflete o impacto hidrodinâmico através do padrão de desgaste observado nas testas da assembléia de foraminíferos presentes na região. Para a realização deste trabalho foram coletadas 10 amostras do sedimento superficial, onde foram identificados 2.775 espécimes pertencentes a 3 subordens, representados por 18 gêneros e 41 espécies bentônicas. Dessas 41 espécies, 10 são consideradas constantes, 10 são acessórias e 21 são acidentais. As espécies predominantes da microfauna na área estudada são: Amphistegina lessonii, Quinqueloculina angulata, Triloculina planciana, Elphidium advenum depressulum, Sorites marginalis, Peneroplis pertusus, Borelis pulchra e Pyrgo patagonica.

A Unique Infaunal Foraminiferal Species Tolerance in Recent and Past Sediments of the Western Pacific Warm Pool (Iodp, Wpwp, Exp. 363)

“…The biogenic sediments of the Potiguar Basin present more diverse and dominant species belonging to the Miliolina (imperforate shells) and Rotaliina (perforated shells) suborders and species with lower dominance belonging to the Textularina suborder (agglutinated), reflecting changes in environmental parameters in this dynamic region. The robust taxonomic composition of the shells from this region indicates high resistance of them, which tolerate salting and dragging and wear to a lesser extent than the binders (Murray, 1991;Araujo & Machado, 2008) and are resistant to wear and tear by transport and dissolution (Bruno et al, 2009;Moraes & Machado, 2001). Some brown colored ones also show signs of abrasion, such as fragmentation and even a yellowish coloration.…”
