An EST screen from the annelid Pomatoceros lamarckii reveals patterns of gene loss and gain in animals [PDF]

open access: yesBMC Evolutionary Biology, 2009
Background Since the drastic reorganisation of the phylogeny of the animal kingdom into three major clades of bilaterians; Ecdysozoa, Lophotrochozoa and Deuterostomia, it became glaringly obvious that the selection of model systems with extensive ...

The Deep Evolution of Ecdysozoa [PDF]

open access: yes, 2022
Ecdysozoa (moulting animals) comprises the protostome Phyla Arthropoda, Kinorhyncha, Loricifera, Nematoda, Nematomorpha, Onychophora, Priapulida and Tardigrada, but our precise understanding of the phylogenetic relationships between these is disputed ...

Identification of proteins from the secretory/excretory products (SEPs) of the branchiuran ectoparasite Argulus foliaceus (Linnaeus, 1758) reveals unique secreted proteins amongst haematophagous ecdysozoa [PDF]

open access: yesParasites & Vectors, 2020
Background It is hypothesised that being a blood-feeding ectoparasite, Argulus foliaceus (Linnaeus, 1758), uses similar mechanisms for digestion and host immune evasion to those used by other haematophagous ecdysozoa, including caligid copepods (e.g. sea

The genome sequence of the Montseny horsehair worm, Gordionus montsenyensis sp. nov., a key resource to investigate Ecdysozoa evolution [PDF]

open access: yesPeer Community Journal
Nematomorpha, also known as Gordiacea or Gordian worms, are a phylum of parasitic organisms that belong to the Ecdysozoa, a clade of invertebrate animals characterized by molting.

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera. [PDF]

open access: yesJ Exp Zool B Mol Dev Evol
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Ancestral morphology of Ecdysozoa constrained by an early Cambrian stem group ecdysozoan [PDF]

open access: yes, 2020
Background: Ecdysozoa are the moulting protostomes, including arthropods, tardigrades, and nematodes. Both the molecular and fossil records indicate that Ecdysozoa is an ancient group originating in the terminal Proterozoic, and exceptional fossil biotas

An Increase in Animal Diversity was Facilitated by Ecologically-Driven Brain Complexity Throughout the Cambrian. [PDF]

open access: yesBioessays
The Brain‐First Hypothesis suggests that the Cambrian transition from animals with simple body plans and simple brains to more complex animals was driven by a selection for brains with increased neural processing, following increased ecological complexity, and the networks underlying brain development were co‐opted to pattern other complex systems ...

Investigating Low-Temperature Stress Responses in Crustacea Aquatic Species Through Comparative Transcriptomics. [PDF]

open access: yesEvol Appl
ABSTRACT Crustaceans, such as shrimp and crabs, are pivotal to global aquaculture, yet their productivity is severely impacted by low‐temperature stress. This study employs comparative transcriptomic and genomic analyses to elucidate the molecular mechanisms underlying crustacean responses to cold stress across five economically significant species ...

A first look at the biodiversity of Loricifera in the southern Gulf of Mexico

open access: yesFrontiers in Marine Science, 2022
Loricifera is a group of marine, meiobenthic invertebrates of microscopic size that are found worldwide. The Loriciferan fauna of the Southern Gulf of Mexico (SGM) remains unknown.

Support for the Ecdysozoa hypothesis regarding the systematics within Protostomia

open access: yes, 2023
Sistematika životinja ima dugu tradiciju u biologiji, a metode molekularne filogenetike u zadnjih nekoliko desetljeća dovele su u pitanje brojne tradicionalne stavove u tom području.
