Palaeontological and Molecular Evidence Linking Arthropods, Onychophorans, and other Ecdysozoa [PDF]
Evolution: Education and Outreach, 2009 Membership of Arthropoda in a clade of molting animals, the Ecdysozoa, has received a growing body of support over the past 10 years from analyses of DNA sequences from many genes together with morphological characters involving the cuticle and its molting.

Profiling G protein-coupled receptors of Fasciola hepatica identifies orphan rhodopsins unique to phylum Platyhelminthes [PDF]
, 2017 G protein-coupled receptors (GPCRs) are established drug targets. Despite their considerable appeal as targets for next-generation anthelmintics, poor understanding of their diversity and function in parasitic helminths has thwarted progress towards GPCR-

ZooTraits: An R shiny app for exploring animal trait data for ecological and evolutionary research
Ecology and Evolution, Volume 14, Issue 5, May 2024.ZooTraits was developed to tackle the challenge of accessing trait datasets by providing an easy‐to‐use, open‐source platform. This app offers three functionalities that will allow users to easily visualize, compare, download, and upload trait data—ExploreTrait, FeedTrait, and GetTrait Abstract Animal trait data are scattered across several datasets ...

Podržanost hipoteze Ecdysozoa u sistematici skupine Protostomia [PDF]
, 2023 Animal systematics has a long tradition in biology, and the methods of molecular phylogenetics have challenged numerous traditional views in this field over the past few decades. Within the group of Protostomia, the question of the position of arthropods is the most prominent.

Papers in Palaeontology, Volume 10, Issue 3, May/June 2024.Abstract The documentation of cuticular micro‐ornament is vital for the taxonomic assignment of palaeoscolecids: vermiform lower Palaeozoic ecdysozoans interpreted as stem‐group priapulans or early diverging panarthropods. This is due to the absence of the character‐rich proboscis and tail hooks in palaeoscolecid material not from Burgess Shale‐type ...

Hox and ParaHox genes in Nemertodermatida, a basal bilaterian clade [PDF]
, 2006 Molecular evidence suggests that Acoelomorpha, a proposed phylum composed of acoel and Nemertodermatida flatworms, are the most basal bilaterian animals.

Frontiers in Neuroscience, 2013 A vital feature in the success of Ecdysozoa is their ability to shed their exoskeleton (a process called ecdysis) such that they can grow or change their morphology.

Mixed evolutionary origins of endogenous biomass-depolymerizing enzymes in animals
BMC Genomics, 2018 Background Animals are thought to achieve lignocellulose digestion via symbiotic associations with gut microbes; this view leads to significant focus on bacteria and fungi for lignocellulolytic systems.

The ommatidia of Arca noae: a three-tier structure with a central light-guiding element for the receptor cell [PDF]
, 2018 The compound eyes of ark clams appear to function as an optical system to trigger shell closure against predators. We have analyzed the structure of the ommatidia of Arca noae by thin section electron microscopy and serial sectioning, Concanavalin A-gold
