Toward a Tree-of-Life for the boas and pythons: multilocus species-level phylogeny with unprecedented taxon sampling.
Recent divergence with gene flow in Tennessee cave salamanders (Plethodontidae: Gyrinophilus) inferred from gene genealogies
Results of coalescent‐based analysis of the distribution of haplotypes among groups reject the allopatric speciation model and support continuous or recurrent genetic exchange during divergence, strongly favour the hypothesis that Tennessee cave salamanders originated from spring salamander via divergence with gene flow.

It is concluded that genetic analysis of biological invasions is justified only under exceptional circumstances and recommended that biologists ask whether the questions to be addressed will materially affect management practice or policy.

The use of recently developed methods for discovering and testing species boundaries and relationships using a multilocus dataset in a widely distributed subterranean teleost fish, Typhlichthys subterraneus, endemic to Eastern North America is used.
EVIDENCE FOR REPEATED LOSS OF SELECTIVE CONSTRAINT IN RHODOPSIN OF AMBLYOPSID CAVEFISHES (TELEOSTEI: AMBLYOPSIDAE)

It is shown that there has been repeated loss of functional constraint of rhodopsin in amblyopsid cavefishes, as at least three cave lineages have independently accumulated unique loss‐of‐function mutations over the last 10.3 Mya.
Patterns of Cave Biodiversity and Endemism in the Appalachians and Interior Plateau of Tennessee, USA
A hotspot of cave biodiversity with a center along the escarpment of the Cumberland Plateau in south-central Tennessee defined by both species richness and endemism that is contiguous with a previously defined hotspot in northeastern Alabama is identified.

Distinctiveness in the face of gene flow: hybridization between specialist and generalist gartersnakes

Patterns of divergence and polymorphism across hybrid zones can provide important clues as to their origin and maintenance and disparity in the level of differentiation across molecular markers indicates that distinctiveness is maintained by strong selection on a few traits despite high gene flow currently or in the recent past.
Scientists' Warning on the Conservation of Subterranean Ecosystems
In light of recent alarming trends in human population growth, climate change, and other environmental modifications, a “Warning to humanity” manifesto was published in BioScience in 2017. This…
Evaluation of eDNA for groundwater invertebrate detection and monitoring: a case study with endangered Stygobromus (Amphipoda: Crangonyctidae)

This study is the first to the authors' knowledge to successfully employ an eDNA approach to detect rare or threatened invertebrates from subterranean ecosystems, including accounting for PCR inhibition and the potential for cryptic genetic diversity.
