Geological dates and molecular rates: fish DNA sheds light on time dependency.
TLDR
This study provides conclusive evidence of time dependency in molecular rates as it is based on a robust calibration system that was applied to closely related taxa, and analyzed using a consistent and rigorous methodology.
Marine dispersal as a pre‐requisite for Gondwanan vicariance among elements of the galaxiid fish fauna
TLDR
Gondwanan vicariance appears to have been preceded by marine dispersal in the few instances where it may explain contemporary galaxiiddistribution, such that these biogeographic mechanisms may sometimes have asynergistic relationship.
Antitropicality of Pacific Fishes: Molecular Insights

TLDR
Divergences within two fish groups were mid-Miocene in age, corresponding to a period suggested for vicariant isolation associated with equatorial warming, but high dispersal potentials complicate the interpretation of biogeographic history.
Complete Mitochondrial DNA Sequences of the Decapod Crustaceans Pseudocarcinus gigas (Menippidae) and Macrobrachium rosenbergii (Palaemonidae)
TLDR
The complete mitochondrial DNA sequence was determined for the Australian giant crab Pseudocarcinns gigas and the giant freshwater shrimp Macrobrachium rosenbergii, the first caridean and only the second brachyuran complete mtDNA sequences, and a source of information that will facilitate surveys of intraspecific variation within these commercially important decapod species.
RIVER CAPTURE, RANGE EXPANSION, AND CLADOGENESIS: THE GENETIC SIGNATURE OF FRESHWATER VICARIANCE
TLDR
It is suggested that the genetic signature of capture is less likely to be retained when river capture merely translocates genetic lineages among established populations, as is inferred for the two galaxiid taxa studied here.
Geological dates and molecular rates: rapid divergence of rivers and their biotas.
TLDR
A survey of freshwater phylogeographic literature reveals numerous examples in which the ages of recent evolutionary events may have been substantially overestimated through the use of "accepted" calibrations, and recommends thatbiologists should start to reassess the conclusions of such studies by using more appropriate molecular calibrations derived from recent geological events.
Molecular phylogeny and zoogeography of the freshwater crayfish genus Cherax Erichson (Decapoda: Parastacidae) in Australia
TLDR
The phylogenetic relationships among Cherax support endemic speciation within geographical regions and indicate that long-distance dispersal has not led to recent speciation as previously hypothesized.
A modified stepping-stone model of population structure in red drum, Sciaenops ocellatus (Sciaenidae), from the northern Gulf of Mexico
TLDR
It is hypothesized that population structure in red drum follows a modified one-dimensional, linear stepping-stone model where gene exchange occurs primarily (but not exclusively) between adjacent bays and estuaries distributed linearly along the coastline.
Extreme intraspecific mitochondrial DNA sequence divergence in Galaxias maculatus (Osteichthys: Galaxiidae), one of the world's most widespread freshwater fish.
TLDR
Molecular clock calibrations suggest that haplotype divergences postdate the fragmentation of Gondwana and point to marine dispersal rather than ancient vicariance as an explanation for the wide distribution of Galaxias maculatus.
