An analysis of ethanol-induced behavioural plasticity in Caenorhabditis elegans

open access: yes, 2009
Ethanol is one of the most widely used and socially acceptable drugs in the world.However its chronic use can lead to serious problems including the development ofdependence.

Patterns of nucleotide polymorphism distinguish temperate and tropical wild isolates of Caenorhabditis briggsae [PDF]

open access: yes, 2006
Caenorhabditis briggsae provides a natural comparison species for the model nematode C. elegans, given their similar morphology, life history, and hermaphroditic mode of reproduction. Despite C.

Expansion microscopy of C. elegans

open access: yeseLife, 2020
We recently developed expansion microscopy (ExM), which achieves nanoscale-precise imaging of specimens at ~70 nm resolution (with ~4.5x linear expansion) by isotropic swelling of chemically processed, hydrogel-embedded tissue. ExM of C. elegans is challenged by its cuticle, which is stiff and impermeable to antibodies.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Operon conservation and the evolution of trans-splicing in the phylum Nematoda [PDF]

open access: yes, 2006
The nematode Caenorhabditis elegans is unique among model animals in that many of its genes are cotranscribed as polycistronic pre-mRNAs from operons.

Clade‐wide morphological and functional variation of the sauropsid columella

open access: yesThe Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Development of equation of motion deciphering locomotion including omega turns of Caenorhabditis elegans

open access: yeseLife
Locomotion is a fundamental behavior of Caenorhabditis elegans (C. elegans). Previous works on kinetic simulations of animals helped researchers understand the physical mechanisms of locomotion and the muscle-controlling principles of neuronal circuits ...

One new species and three new records of Chrysis Linnaeus from China (Hymenoptera, Chrysididae)

open access: yesZooKeys, 2017
Four Chinese Chrysis species-groups, the antennata, capitalis, elegans, and maculicornis species-groups, are discussed. Chrysis lapislazulina Rosa & Xu, sp. n. is described in the elegans species-group; and three species, C. brachyceras Bischoff,

C. elegans TRP Channels [PDF]

open access: yes, 2010
Transient receptor potential (TRP) channels represent a superfamily of cation channels found in all eukaryotes. The C. elegans genome encodes seventeen TRP channels covering all of the seven TRP subfamilies. Genetic analyses in C. elegans have implicated TRP channels in a wide spectrum of behavioral and physiological processes, ranging from sensory ...
