EF-hand proteins in onychophorans as compared to tardigrades and other ecdysozoans

open access: yesJournal of Limnology, 2013
To learn more about the regulation of muscle contraction in the structural and functionally different muscles in Ecdysozoa, we have analysed the four EF-hand proteins calmodulin (CaM), troponin C (TnC), essential myosin light chain (eMLC) and regulatory ...

Insights into the microRNA landscape of Rhodnius prolixus, a vector of Chagas disease

open access: yesScientific Reports, 2023
The growing interest in microRNAs (miRNAs) over recent years has led to their characterization in numerous organisms. However, there is currently a lack of data available on miRNAs from triatomine bugs (Reduviidae: Triatominae), which are the vectors of ...

Prioritising research on endocrine disruption in the marine environment: a global perspective

open access: yesBiological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

On the phylogenetic position of Myzostomida: can 77 genes get it wrong? [PDF]

open access: yes, 2009
Background Phylogenomic analyses recently became popular to address questions about deep metazoan phylogeny. Ribosomal proteins (RP) dominate many of these analyses or are, in some cases, the only genes included.

Palaeoscolecids from the early Cambrian Guanshan biota, Yunnan Province, China

open access: yesPapers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract Palaeoscolecidomorphs (Palaeoscolecida and Cricocosmiidae) are widespread early Palaeozoic worms crucial to understanding the early evolution of Ecdysozoa. They are well known from the early–middle Cambrian of the Yangtze Platform of South China, but research has disproportionately focused on the well‐known Cambrian Stage 3 Chengjiang biota of

Neuronal tracing of oral nerves in a velvet worm – Implications for the evolution of the ecdysozoan brain

open access: yesFrontiers in Neuroanatomy, 2014
As one of the closest relatives of arthropods, Onychophora plays an important role in understanding the evolution of arthropod body plans. Currently there is controversy surrounding the evolution of the brain among the ecdysozoan clades, which shows a ...

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 8, Page 505-516, December 2025.
Epithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.

The Resilience of Life to Astrophysical Events

open access: yesScientific Reports, 2017
Much attention has been given in the literature to the effects of astrophysical events on human and land-based life. However, little has been discussed on the resilience of life itself.
