Levels of Sex Steroids in Plethodontid Salamanders: A Comparative Study Within the Genus Aneides [PDF]
Derived monomorphism is a condition in which males and females are phenotypically similar, but the similarity is derived. Derived monomorphism typically evolves from sexual dimorphism or from a different monomorphic state.

Extensive Admixture Among Karst‐Obligate Salamanders Reveals Evidence of Recent Divergence and Gene Exchange Through Aquifers [PDF]
Karst ecosystems often contain extraordinary biodiversity, but the complex underground aquifers of karst regions present challenges for assessing and conserving stygobiont diversity and investigating their evolutionary history.

Differences in composition and potential function of the bacterial communities of cave- and surface-dwelling Mexican salamanders [PDF]
Caves are a challenging environment for many organisms to inhabit, and many cave-dwelling animals are endemic to particular cave systems. Microorganisms in caves have been shown to have a high biosynthetic capacity, likely as a result of intense ...

Can Ectoparasite Phylogenetics Shed Light on Host Evolution? The <i>Batracobdella</i> Leeches and <i>Speleomantes</i> Salamanders' System. [PDF]
Phylogenetic relationships of symbionts can inform about the evolution of their hosts. In this study, we reconstructed the evolutionary relationships among Sardinian salamander ectoparasitic leeches to resolve evolutionary discordances among their hosts, the Sardinian Speleomantes salamander species, and proposed novel evolutionary hypotheses that ...

The simple morphology of the sunfish heart. [PDF]
Jensen and Lauridsen describe the least curved vertebrate heart to date in seven specimens of Ocean sunfish. By comparison to multiple vertebrates, it is concluded that the highly unusual heart is a recent evolution that relates in part to the extraordinary shape of the body.

Evaluating the Use of Environmental DNA as a Method to Determine Occupancy and Distribution of Coeur d'Alene Salamanders in Montana. [PDF]
The purpose of this project was to evaluate the efficacy of eDNA sampling to determine occupancy of Coeur d'Alene salamanders, an “imperiled” species in Montana. Previous methods used to identify occupied sites were haphazard with no measure of detection probability. Due to the unique habitat used by these salamanders (seeps and waterfall spray zones),

Many forested freshwater wetlands have been altered or destroyed, and wetlands are constructed to offset loss. However, they do not always replace the function of natural wetlands.

A new maximum body size record for the Berry Cave Salamander (Gyrinophilus gulolineatus) and genus Gyrinophilus (Caudata, Plethodontidae) with a comment on body size in plethodontid salamanders [PDF]
Lungless salamanders in the family Plethodontidae exhibit an impressive array of life history strategies and occur in a diversity of habitats, including caves. However, relationships between life history, habitat, and body size remain largely unresolved.

Effects of life history strategies and habitats on limb regeneration in plethodontid salamanders. [PDF]
Abstract Background Salamanders are the only tetrapods that exhibit the ability to fully regenerate limbs. The axolotl, a neotenic salamander, has become the model organism for regeneration research. Great advances have been made providing a detailed understanding of the morphological and molecular processes involved in limb regeneration.
