Deep‐sea meiofaunal communities in the south‐eastern Levantine basin and their shaping factors – Morphological‐taxonomy‐free metabarcoding approach

open access: yesEcology and Evolution, Volume 14, Issue 3, March 2024.
The hitherto poorly investigated meiofaunal communities of the south‐eastern part of the Levantine basin were characterized and their relationships with sedimentary and bottom terrain parameters were interpreted. The construction of community composition profiles took an approach that combined metabarcoding with sample reads normalization by abundance.

Effects of low frequency rectangular electric pulses on Trichoplax (Placozoa)

open access: yes, 2020
The effect of extremely low frequency electric and magnetic fields (ELF-EMF) on plants and animals including humans is quite a contentious issue. Little is known about ELF-EMF effect on hydrobionts, too.

Growth and Behavior of Trichoplax adhaerens: First Record of the Phylum Placozoa in Hawaii [PDF]

open access: yes, 1989
I report here the first record of Trichoplax adhaerens F. E. Schulze (phylum Placozoa) in Hawaii. Individuals were found on glass slides placed in the seawater system of the Pacific Biomedical Research Center on Kewalo Basin, Oahu, during November and

Molecular evolution of peptide signaling in Placozoa and Cnidaria

open access: yes, 2020
Background: Nervous systems are found almost throughout the animal kingdom, but when and how the nervous system evolved are still some of the big, unanswered questions in biology.

The Evolutionary History of The Orexin/Allatotropin GPCR Family: From Placozoa and Cnidaria to Vertebrata [PDF]

open access: yes, 2019
Peptidic messengers constitute a highly diversified group of intercellular messengers widely distributedin nature that regulate a great number of physiological processes in Metazoa.

Molecular origin of mesoderm : conservation of T-box genes in non-bilaterian animals [PDF]

open access: yes, 2003
Several members of the T-box gene family were characterized from cnidarians, ctenophores, sponges and placozoans, which are considered as the four metazoan phyla at the basis of animal evolution leading to bilaterians.

Diversity and biogeography of the unique, tropical phylum Placozoa [PDF]

open access: yes, 2008
Phylum Placozoa consists of only a single described species, Trichoplax adhaerens. Although organisms within the phylum are morphologically indistinct, recent molecular evidence indicates cryptic diversity.

The Trox-2 Hox/ParaHox gene of Trichoplax (Placozoa) marks an epithelial boundary.

open access: yes, 2004
Hox and ParaHox genes are implicated in axial patterning of cnidarians and bilaterians, and are thought to have originated by tandem duplication of a single "ProtoHox" gene followed by duplication of the resultant gene cluster.

Morphological and physiological aspects of movement and contractility in Trichoplax adhaerens (Placozoa)

open access: yes, 2011
The Placozoa represent one of the early metazoan branches and are of interest for comparative studieson several evolutionary aspects in the Metazoa. Despite of the relatively simple placozoan morphology,many functional aspects remain partly or completely
