Descripción
The analysis of ubiquitous material of individual growth stages of the foraminifer Buccella from the Bahía Blanca estuary reveals a wide range of morphogenetic expressions. The observations of morphological changes expressed during ontogeny display a continuous record of transitional stages that are reflected in juvenile, adolescent, and adult test shapes. The morphological features of individual growth stages were found to match specifications that were previously used to delineate individual species of Buccella from around South America. This indicates that juvenile, adolescent, and adult morphotypes of Buccella do not represent end members of individual species, subspecies, forms, or varieties. In fact, they constitute a continuous sequence of ontogenetic stages that ultimately result in the morphotype that was originally described and depicted by d'Orbigny, in the first half of the nineteenth century, under the name Rotalina peruviana (currently known as Buccella peruviana). The morphological expressions of juvenile, adolescent, and adult forms have potential applications for paleoecological studies in South American waters.
A análise das diferentes fases de crescimento do foraminífero Buccella, com base em rico material recuperado do Estuário de Bahia Blanca, revelou uma vasta gama de expressões morfogenéticas. As observações de alterações morfológicas durante a ontogenia estão expressas num registo contínuo de estágios transicionais que estão refletidos nas diferentes fases de crescimento, i.e., nos juvenis, adolescentes e adultos. As características morfológicas das fases individuais de crescimento coincidem com as especificações utilizadas anteriormente no delineamento individual das espécies de Buccella originárias da América do Sul. Isto significa que os diferentes morfotipos correspondentes às fases juvenil, adolescente e adulto no gênero Buccella não representam membros finais de espécie, subespécie, forma ou variedade. Na verdade, eles constituem uma sequência contínua de fases ontogénicas que, em última análise, resultam no morfotipo originalmente descrito e retratado por d’Orbigny, na primeira metade do século dezenove, sob o nome Rotalina peruviana (atualmente denominada Buccellaperuviana). As expressões morfológicas de formas juvenis, adolescentes e adultas têm aplicações potenciais para estudos paleoecológicos em águas sul-americanas.
