... account for 86% of the total foraminiferal assemblage. Few planktonic foraminifera were found in the PRE, accounting for 0.74% of the total specimens, and were only found in areas with a water depth > 20 m. The distribution of the 23 relatively abundant species, all of which are benthic, is illustrated...

We measure test diameter and surface area of over 500 individuals of the species Globoconella puncticulata using two-dimensional images...

... and the variation within and between lagoons located less than 40 km apart. Abundances of planktonic and other nearshore foraminifera show that Los Peñasquitos lagoon was much more open in the mid-Holocene compared to today. Palynological data provide the first documentation of mangrove migration as far north...

... in paleobiological and paleoenvironmental studies and as environmental proxies in the modern ocean, the taxonomy of living planktonic foraminifera as morphospecies should be founded on a good understanding of their populations. Truncorotalia crassaformis (Galloway & Wissler) demonstrates the present...
