A Whole‐Genome Investigation of Mitonuclear Discordance in the Trematode Parasite Atriophallophorus winterbourni

open access: yesMolecular Ecology, Volume 35, Issue 10, May 2026.
ABSTRACT Faster evolution of mitochondrial genomes relative to nuclear genomes creates selective pressure on nuclear genes involved in mitochondrial function to preserve mitonuclear compatibility required for energy production. In isolated populations, such coevolution occurs independently.

Landscape genetics reveal broad and fine‐scale population structure due to landscape features and climate history in the northern leopard frog (Rana pipiens) in North Dakota [PDF]

open access: yes, 2018
Prehistoric climate and landscape features play large roles structuring wildlife populations. The amphibians of the northern Great Plains of North America present an opportunity to investigate how these factors affect colonization, migration, and current

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Life history linked to immune investment in developing amphibians [PDF]

open access: yes, 2013
The broad diversity of amphibian developmental strategies has been shaped, in part, by pathogen pressure, yet trade-offs between the rate of larval development and immune investment remain poorly understood. The expression of antimicrobial peptides (AMPs)

Phenotypic Plasticity Across Gradients of Predation and Competition in Larval Amphibians

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Many taxa encounter a wide range of conditions for any particular environmental variable and they experience variation in multiple environmental variables simultaneously, which may have interactive effects if different environmental types induce opposing phenotypes.

Effect of Sciatic Nerve Transection on acetylcholinesterase activity in spinal cord and skeletal muscles of the bullfrog Lithobates catesbeianus

open access: yesBrazilian Journal of Biology, 2017
Sciatic nerve transection (SNT), a model for studying neuropathic pain, mimics the clinical symptoms of “phantom limb”, a pain condition that arises in humans after amputation or transverse spinal lesions.

Genome‐Wide Characterization of Sex‐Linked Regions in the Sangzhi Horned Toad (Boulenophrys sangzhiensis) Reveals Complex Sex Determination Mechanisms

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Sex chromosomes in amphibians exhibit substantial variability and often remain largely homomorphic, providing a powerful system for studying sex determination. The Sangzhi horned toad (Boulenophrys sangzhiensis) is an ideal model, but limited genomic resources have hindered insights into sex determination mechanisms.
