In the balanced lethal system in Triturus newts, individuals that inherit either the 1A or the 1B version of chromosome 1 twice will experience developmental arrest and die halfway embryonic develo…

Genetic pollution, gene flow from invasive to native species species, poses a complicated conservation question. It is well-known in crested newts. Why should we care about genetic pollution? To pu…

Neurergus crocatus by Michael Fahrbach The Near Eastern newts of the genus Neurergus are spectacular salamanders that seem to lack a proper common name. Because many of the species have at one time…

The balanced lethal system in Triturus newts is well-suited to teach biology students basic principles about natural selection and genetic linkage. This was the motivation behind a paper led by my …

Assessing how genetic diversity is spatially structured underlies many research questions in evolutionary ecology and contributes to understanding the factors implicated in population declines and ext...

Lissotriton vulgaris schmidtleri by Michael Fahrbach Relationships within the newt genus Lissotriton, which includes the smooth newt, have always been difficult to interpret. Similarly, the taxonom…

The awesome banded newt genus comprises three cryptic species that are really old and have little to no genetic exchange between them. However, the ancestral banded newt appears to have radiated in…

A genetic flaw dooms half of all crested newts to die before they hatch – now we know how this baffling evolutionary quirk came about
