Dynamics of X chromosome hyper-expression and inactivation in male tissues during stick insect development. [PDF]

open access: yesPLoS Genetics
Differentiated sex chromosomes are frequently associated with major transcriptional changes: the evolution of dosage compensation (DC) to equalize gene expression between the sexes and the establishment of meiotic sex chromosome inactivation (MSCI).

Parthenogenetic Females of the Stick Insect Clitarchus hookeri Maintain Sexual Traits [PDF]

open access: yesInsects, 2019
The New Zealand stick insect Clitarchus hookeri has both sexual and parthenogenetic (all-female) populations. Sexual populations exhibit a scramble competition mating system with distinctive sex roles, where females are signalers and males are searchers,

Dynamics of sex-biased gene expression during development in the stick insect Timema californicum. [PDF]

open access: hybridHeredity (Edinb), 2022
Sexually dimorphic phenotypes are thought to arise primarily from sex-biased gene expression during development. Major changes in developmental strategies, such as the shift from hemimetabolous to holometabolous development, are therefore expected to ...

X chromosomes show relaxed selection and complete somatic dosage compensation across Timema stick insect species. [PDF]

open access: hybridJ Evol Biol, 2022
Sex chromosomes have evolved repeatedly across the tree of life. As they are present in different copy numbers in males and females, they are expected to experience different selection pressures than the autosomes, with consequences including a faster ...

Calcium imaging of CPG-evoked activity in efferent neurons of the stick insect. [PDF]

open access: yesPLoS ONE, 2018
The stick insect is a well-established experimental animal to study the neural basis of walking. Here, we introduce a preparation that allows combining calcium imaging in efferent neurons with electrophysiological recordings of motor neuron activity in ...

A Reversible Secret Image Sharing Scheme Based on Stick Insect Matrix

open access: yesIEEE Access, 2020
This paper first proposes a generation algorithm of a stick insect matrix. Then, a novel reversible secret image sharing scheme based on the stick insect matrix is presented.

DNA methylation differences between stick insect ecotypes

open access: yesMolecular Ecology, 2023
AbstractEpigenetic mechanisms, such as DNA methylation, can influence gene regulation and affect phenotypic variation, raising the possibility that they contribute to ecological adaptation. Beginning to address this issue requires high‐resolution sequencing studies of natural populations to pinpoint epigenetic regions of potential ecological and ...

Comparative Neuroanatomy of the Mechanosensory Subgenual Organ Complex in the Peruvian Stick Insect, Oreophoetes peruana [PDF]

open access: hybridBrain, Behavior and Evolution, 2022
The subgenual organ complex in the leg of Polyneoptera (Insecta) consists of several chordotonal organs specialized to detect mechanical stimuli from substrate vibrations and airborne sound.

Multiple Identified Neurons and Peripheral Nerves Innervating the Prothoracic Defense Glands in Stick Insects Reveal Evolutionary Conserved and Novel Elements of a Chemical Defense System [PDF]

open access: goldFrontiers in Ecology and Evolution, 2017
The defense glands in the dorsal prothorax are an important autapomorphic trait of stick insects (Phasmatodea). Here, we study the functional anatomy and neuronal innervation of the defense glands in Anisomorpha paromalus (Westwood, 1859 ...
