“…Because foraminifera are among the most prolific reefal faunal elements, invasions may affect ecosystem functioning that ultimately affects the native biota. As has been previously shown [15], the invasion of amphisteginids into the Mediterranean Sea impacts the faunal composition, biodiversity and carbonate productivity and results in substantial faunal alterations (see also [79]). …”

The distribution of modern symbiont-bearing larger foraminifera is confined to tropical and subtropical shallow water marine habitats and a narrow range of environmental variables (e.g. temperature). Most of today's taxa are restricted to tropical and subtropical regions (between 30°N and 30°S) and their minimum temperature limits are governed by the 14 to 20°C isotherms. However, during times of extensive global warming (e.g., the Eocene and Miocene), larger foraminifera have been found as far north as 50°N (North America and Central Europe) as well as towards 47°S in New Zealand. During the last century, sea surface temperatures have been rising significantly. This trend is expected to continue and climate change scenarios for 2050 suggest a further increase by 1 to 3°C. We applied Species Distribution Models to assess potential distribution range changes of three taxa of larger foraminifera under current and future climate. The studied foraminifera include Archaias angulatus, Calcarina spp., and Amphistegina spp., and represent taxa with regional, superregional and global distribution patterns. Under present environmental conditions, Amphistegina spp. shows the largest potential distribution, apparently due to its temperature tolerance. Both Archaias angulatus and Calcarina spp. display potential distributions that cover currently uninhabited regions. Under climate conditions expected for the year 2050, all taxa should display latitudinal range expansions between 1 to 2.5 degrees both north- and southward. The modeled range projections suggest that some larger foraminifera may colonize biogeographic regions that so far seemed unsuitable. Archaias angulatus and Calcarina spp. also show an increase in habitat suitability within their native occurrence ranges, suggesting that their tolerance for maximum temperatures has yet not been fully exploited and that they benefit from ocean warming. Our findings suggest an increased role of larger foraminifera as carbonate producers and reef framework builders in future oceans.

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. RESUMO-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 Buccella peruviana). As expressões morfológicas de formas juvenis, adolescentes e adultas têm aplicações potenciais para estudos paleoecológicos em águas sul-americanas.

“…Esta reconstrucción paleogeográfica del sector meridional del estuario se ha observado en lagunas atlánticas y mediterráneas actuales (p.e. Ruiz et al, 2006;Cearreta et al, 2007;Coccioni et al, 2009;Calvo-Marcilese & Langer, 2010;Alday et al, 2013).

Durante el periodo romano (siglo III a.C.-siglo V d.C.), las zonas próximas a la actual desembocadura del río Guadalquivir estaban ocupadas por una laguna interior con conexión marina, a partir de la interpretación paleoambiental de las asociaciones de foraminíferos bentónicos obtenidos en un sondeo situado en el Parque Nacional de Doñana. Sus zonas internas estaban ocupadas por llanuras mareales arcillosas, que sufrieron los efectos de una tormenta hacia finales del siglo I d.C. La comparación con los ostrácodos del mismo sondeo confirma esta reconstrucción y los datos paleogeográficos aportados por diversos cronistas, si bien estos microcrustáceos detectan de manera más precisa los cambios paleoambientales en estos medios litorales.
