Abstract Marine planktonic microfossils have provided some of the best examples of evolutionary rates and patterns on multi-million-year time scales, including many instances of gradual evolution. Lineage splitting as a result of speciation has also been claimed, but all such studies have used subjective visual species discrimination, and interpretation has often been complicated by relatively small sample sizes and oceanographic complexity at the study sites. Here we analyze measurements on a… Expand
Mosaic evolution in the middle Miocene planktonic foraminifera Fohsella lineage
TLDR
It is suggested that overemphasis on the evolution of some single trait, such as the edge-view outline, from narrow geographic ranges has significantly underestimated the dynamic evolutionary history of this group. Expand
Evolutionary Transition in the Late Neogene Planktonic Foraminiferal Genus Truncorotalia
TLDR
It is shown that foraminiferal lineages are not necessarily gradual and can experience significant and rapid transitions along their evolutionary trajectories and reaffirm the utility of multivariate datasets for their future research. Expand
Taxonomy, Stratigraphy and Phylogeny of the Middle Miocene Fohsella Lineage: Geometric Morphometric Evidence
The taxonomy and phylogeny of the planktonic foraminifera Fohsella lineage has been controversial for nearly 50 years, despite its widespread application in Middle Miocene stratigraphy. We haveExpand
Coiling directions in the planktonic foraminifer Pulleniatina: A complex eco-evolutionary dynamic spanning millions of years
TLDR
It is suggested that major fluctuations in coiling ratio are caused by cryptic populations replacing one another in competitive sweeps, a mode of evolution that is more often associated with asexual organisms than with the classical ‘biological species concept’. Expand
Towards a morphological metric of assemblage dynamics in the fossil record: a test case using planktonic foraminifera
TLDR
This work presents and test a new high-throughput approach for analysing community shape in the fossil record using semi-three-dimensional (3D) morphometrics from vertically stacked images (light microscopic or photogrammetric). Expand
Evolutionary prospection in the Neogene planktic foraminifer Globorotalia menardii and related forms from ODP Hole 925B (Ceara Rise, western tropical Atlantic): evidence for gradual evolution superimposed by long distance dispersal?
Evolutionary prospection is the study of morphological evolution and speciation in calcareous plankton from selected time-slices and key sites in the world oceans. In this context, the NeogeneExpand
Revisiting a Landmark Study System: No Evidence for a Punctuated Mode of Evolution in Metrarabdotos
TLDR
It is consistently fail to find variation in the evolutionary process during within-lineage evolution compared with cladogenetic events: the rates of evolution, the strength of selection, and the directions traveled in multivariate morphospace are not different when comparing evolution within lineages and at speciation events in Metrarabdotos.

Future-proofing the Cenozoic macroperforate planktonic foraminifera phylogeny of Aze & others (2011)
TLDR
Both macroevolutionary and biostratigraphic communities are now equipped with an enduring phylogenetic database of Cenozoic macroperforate planktonic foraminiferal morphospecies and lineages for which both graphics and content can be visualised together. Expand
Adaptive ecological niche migration does not negate extinction susceptibility
TLDR
Analysis of the isochronous extinction of two members of the planktonic foraminiferal genus Dentoglobigerina shows disruptive selection differentially compounded by permanent ecological niche migration, “pre-extinction gigantism”, and photosymbiont bleaching prior to extinction. Expand
Adaptive Ecological Niche Migration does not Negate Extinction Susceptibility
Extinction rates in the modern world are currently at their highest in 66 million years and are likely to increase with projections of future climate change. Our knowledge of modern-day extinctionExpand

Molecular evidence of cryptic speciation in planktonic foraminifers and their relation to oceanic provinces.
TLDR
The genetic data reveal the presence of three cryptic species, whose distribution is clearly correlated to hydrographic provinces, and particularly to sea-surface total chlorophyll a concentration, and suggest that a considerable part of the diversity among planktonic foraminifers has been overlooked in morphological taxonomies. Expand
A phylogeny of Cenozoic macroperforate planktonic foraminifera from fossil data
TLDR
The phylogeny is developed from a large body of palaeontological work that details the evolutionary relationships and stratigraphic (time) distributions of species‐level taxa identified from morphology (‘morphospecies’). Expand
The genetic diversity of planktic foraminifera and the global distribution of ribosomal RNA genotypes
TLDR
An overview of the genetic and biogeographic data available to date for the planktic foraminifera is provided and global biogeographies highlighting the distribution of genetic types in the eight planktics foraminiferal morphospecies for which detailed molecular evidence is available are presented. Expand
Pelagic species diversity, biogeography, and evolution
TLDR
It seems likely that vicariant and allopatric models for speciation are far less important in pelagic evolution than sympatric or parapatric speciation in which dispersal is not limiting. Expand
What is gradualism? Cryptic speciation in globorotaliid foraminifera
TLDR
Analysis of the evolution of the Globorotalia (Fohsella) lineage of planktic foraminifera suggests that reproductive ecology and shell shape have evolved independently in this group, and anagenesis masks at least one speciation event that is apparent only in the isotopic evidence for a change in reproductive ecology.

Phyletic gradualism in a Late Cenozoic planktonic foraminiferal lineage; DSDP Site 284, southwest Pacific
Shape measurements have been made on planktonic foraminifera from a South Pacific Late Miocene to Recent temperate evolutionary lineage (Globorotalia conoidea through intermediate forms to G. inflataExpand
A lineage phylogeny for the Paleogene planktonic foraminifera
TLDR
In this phylogeny, an attempt is made to delineate lines of genetic descent through lineages, rather than relationships among typologically defined morphospecies, to help elucidate patterns of evolution in the Paleogene planktonic foraminifera by allowing cladogenetic and anagenetic modes of evolution to be identified. Expand
Sympatric speciation and phyletic change in Globorotalia truncatulinoides
TLDR
Speciation, with continuous geographic co-oc- currence of ancestor and descendant forms, occurred simultaneously at both localities over a period of -500,000 years, suggesting a sympatric speciation process that involved a large, geographically extensive population. Expand
Atlantic paleogene planktonic foraminiferal bioprovincial indices
TLDR
Morphologies and wall features of Paleogene planktonic foraminifera are useful for delimiting paleobioprovinces and for the interpretation of Paleo-oceanography and can also be useful biogeographic tools. Expand
