Grass fly evolution unlocked: Phylogenomics and classification of worldwide Chloropidae (Diptera)

open access: yesSystematic Entomology, Volume 51, Issue 2, April‐June 2026.
Phylogenomics resolves deep relationships in Chloropidae. New framework for global Chloropidae classification. Novel morphological synapomorphy for grass flies. Abstract Chloropidae, commonly known as grass flies, is a hyper‐diverse family of true flies thriving in terrestrial ecosystems around the world with importance to conservation and economy ...

Heads or tails first? Evolution of fetal orientation in ichthyosaurs, with a scrutiny of the prevailing hypothesis

open access: yesBMC Ecology and Evolution, 2023
According to a longstanding paradigm, aquatic amniotes, including the Mesozoic marine reptile group Ichthyopterygia, give birth tail-first because head-first birth leads to increased asphyxiation risk of the fetus in the aquatic environment.

Clinal Variation in Reproductive Modes and Offspring Body Condition Across a Contact Zone of a Bimodal Viviparous Salamander

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We examined clinal gradients in reproductive modes and associated offspring body condition across a hybrid zone between two bimodal viviparous subspecies of Salamandra salamandra. We found a clear cline in reproductive modes, with pure modes at the extremes and mixed modes in central populations.

Notes on the Reproductive Biology of the Alabama Red Hills Salamander (Phaeognathus hubrichti ) [PDF]

open access: yes, 2003
Living Amphibia exhibit two major life history modes, possession of an aquatic larval stage or direct development, with the latter assumed to be the derived evolutionary condition (Duellman and Trueb 1986, Wake 1989).

Spatial Structure Explains Morphological Variation Better Than Climatic Gradients in the South American Rattlesnake (Crotalus durissus)

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We evaluated whether climatic gradients or spatial structure better explain body size variation in the South American rattlesnake (Crotalus durissus) across its wide geographic range. After explicitly accounting for spatial autocorrelation, climatic variables were not significant predictors of body size in either sex, whereas sex‐specific spatial ...

No Evidence for Pace of Life Evolution Along Elevational Gradients in Squamate Reptiles

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
Ecological conditions can significantly influence the trade‐off between survival, growth, and reproduction, leading to evolutionary divergence in life‐history traits among populations experiencing different environments. The pace of life syndrome hypothesis (POLS) proposes that additional suites of traits, from physiology to behaviour, adaptively co ...

The Sensory Ecology of Tsetse Flies: Neuroscience Perspectives on a Disease Vector

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 2, January 2026.
Tsetse flies (Glossina sp.) are important disease vectors that feed on vertebrate blood. Host‐seeking depends on a combination of sensory systems, from long‐range senses like olfaction and vision, to shorter‐range senses such as audition, mechanosensation, thermosensation and taste.
