The completion of the Panamanian Isthmus is one of the greatest natural experiments in evolution, sending multiple species pairs from a broad range of taxonomic groups on independent evolutionary trajectories. The resulting transisthmian sister species have been used as model systems for examining consequences that accompany cessation of gene flow in formerly panmictic populations. However, variance in pairwise genetic distances of these “geminates” often exceeds expectations, seemingly…

Molecular phylogenetics reveals differential divergence of coastal snails separated by the Isthmus of Panama.

Base-substitution mutation rate across the nuclear genome of Alpheus snapping shrimp and the timing of isolation by the Isthmus of Panama

The results contradicted recent suggestions that the closure of the Isthmus was completed much earlier (around 10 Ma), as mutation rates based on an early calibration resulted in uncharacteristically low genomic mutation rates.

Phylogeography and diversification history of the day-gecko genus Phelsuma in the Seychelles islands

The results highlight not only the necessity of clarifying the role of ecology and interspecific interactions in this group’s morphological diversification and community assemblage, but also the importance of co-evolutionary mechanisms and their importance for appropriate conservation of island biodiversity.

Crossing the species barrier: genomic hotspots of introgression between two highly divergent Ciona intestinalis species.

The history and degree of isolation of two cryptic and partially sympatric model species are clarified and a methodological framework to investigate genome-wide heterogeneity (GWH) at various stages of speciation process is provided.

The anatomy of a ‘suture zone’ in Amazonian butterflies: a coalescent‐based test for vicariant geographic divergence and speciation

It is suggested that Pleistocene climatic forcing cannot readily explain this Peruvian suture zone, and lineage‐specific biological traits, such as characteristic distances of gene flow or varying rates of parapatric divergence, may be of greater importance.

Multi-Locus Phylogeny of Sponge-Dwelling Snapping Shrimp (Caridea: Alpheidae: Synalpheus) Supports Morphology-Based Species Concepts

A new phylogenetic tree describing relationships between 40 different species from the S. gambarelloides-group in the Caribbean is constructed, providing further evidence for the monophyly of this group and resolving the molecular relationships within many recently described species complexes.

First Worldwide Molecular Phylogeny of the Morphologically and Ecologically Hyperdiversified Snapping Shrimp Genus Alpheus (Malacostraca: Decapoda).

Molecular and morphological differentiation between two Miocene-divergent lineages of Amazonian shrimps, with the description of a new species (Decapoda, Palaemonidae, Palaemon)

Both molecular and morphological data support the taxonomic validity of both Palaemon carteri and PalAemon ivonicus, refuting the hypothesis of synonymy.

Revisiting the insect mitochondrial molecular clock: the mid-Aegean trench calibration.

A well-established biogeographic barrier is used, the mid-Aegean trench separating the western and eastern Aegean archipelago, to estimate substitution rates in tenebrionid beetles, and a divergence rate of 3.54% My(-1) for the cox1 gene was obtained under the preferred partitioning scheme and substitution model selected using Bayes factors.

Early Pleistocene divergence of Pelagia noctiluca populations (Cnidaria, Medusozoa) between the Atlantic Ocean and the Mediterranean Sea

The estimates suggest the origin for a putative common ancestor of Clades I and II around 2.57 Ma, roughly corresponding to the Gelasian stage of the early Pleistocene, and could explain the origin of the two P. noctiluca clades.

Patterns of divergence exhibited by allozymes and the mitochondrial COI gene are highly concordant for 15 pairs of snapping shrimp in the genus Alpheus, indicating that they provide a reasonable basis for estimating time since cessation of gene flow.

PERSPECTIVE: GENE DIVERGENCE, POPULATION DIVERGENCE, AND THE VARIANCE IN COALESCENCE TIME IN PHYLOGEOGRAPHIC STUDIES

It is shown that phylogeographic studies in vertebrates suggest that divergence of alleles in ancestral species can comprise from less than 10% to over 50% of the total divergence between sister species, suggesting that the problem of ancestral polymorphism in dating population divergence can be substantial.

Divergence in proteins, mitochondrial DNA, and reproductive compatibility across the isthmus of Panama.

Measurements of biochemical and reproductive divergence for seven closely related, transisthmian pairs of snapping shrimps indicate, however, that isolation was staggered rather than simultaneous, and the four least divergent pairs provide the best estimate for rates of molecular divergence and speciation.

Evidence for three major clades within the snapping shrimp genus Alpheus inferred from nuclear and mitochondrial gene sequence data.

Phylogenies for Alpheus suggest that specialized ecological requirements and modified claw morphologies have evolved independently several times and support the sister species status of transisthmian pairs analyzed previously, although very similar pairs were not always resolved with the more slowly evolving nuclear loci.

This work has measured protein divergence by electrophoresis and mitochondrial DNA differentiation by restriction fragment length polymorphism analysis in three pairs of sea urchin species believed to have resulted from the simultaneous fragmentation of ranges of marine species by the emergence of the Isthmus of Panama, about 3 million years ago.

Multilocus Methods for Estimating Population Sizes, Migration Rates and Divergence Time, With Applications to the Divergence of Drosophila pseudoobscura and D. persimilis

A Markov chain Monte Carlo method for estimating the posterior probability distribution of model parameters is applied to a large multilocus data set from Drosophila pseudoobscura and D. persimilis, with considerable variation in gene flow estimates among loci, in both directions between the species.

TEST FOR SIMULTANEOUS DIVERGENCE USING APPROXIMATE BAYESIAN COMPUTATION

A flexible approximate Bayesian computational (ABC) framework that can test for simultaneous divergence (TSD) using a hierarchical model that incorporates idiosyncratic differences in demographic history across taxon pairs is introduced and is shown to be accurate even with single-locus mitochondrial DNA (mtDNA) data.

Mitochondrial pseudogenes are pervasive and often insidious in the snapping shrimp genus Alpheus.

It is shown that multiple DNA sequences, similar to the mitochondrial cytochrome oxidase I (COI) gene, occur within single individuals in at least 10 species of the snapping shrimp genus Alpheus, and that genetic material has been repeatedly transferred from the mtDNA to the nuclear genome of snapping shrimp.

Use of Panamanian sea urchins to test the molecular clock

Evidence is presented from sea urchins separated by the Isthmus of Panama which indicates that even the compromise position of the ‘molecular clock’ hypothesis is not tenable.
