Coelomocytes: Biology and Possible Immune Functions in Invertebrates with Special Remarks on Nematodes

open access: yesInternational Journal of Zoology, Volume 2009, Issue 1, 2009., 2009
All metazoans are exposed to a wide range of microbes and have evolved complex immune defenses used to repel infectious agents. Coelomocytes play a key role in the defense reactions of most invertebrates. They are involved in important immune functions, such as phagocytosis, encapsulation, graft rejection, and inflammation, as well as the synthesis and

Reproductive Interference Alters Species Coexistence in Nematodes due to Asymmetric Sperm‐Induced Harm

open access: yesEcology Letters, Volume 28, Issue 1, January 2025.
We test how reproductive interference from inter‐species mating between sympatric Caenorhabditis nematodes can influence species coexistence and exclusion. We demonstrate that females from the species with higher intrinsic population growth experience reduced lifespan and fecundity due to incomplete interspecies mate discrimination that leads to ...

One new Aceria species (Acari: Eriophyoidea) from Dogijan village in Iran

open access: yesPersian Journal of Acarology
During a field survey of eriophyoid mites in Dogijan village (Marand county, East Azerbaijan province, Iran) in late spring 2023, one new eriophyid species (Acari: Eriophyoidea: Eriophyidae) on Chardinia orientalis (L.) Kuntze (Asteraceae) was ...

Another tool in the toolbox: Aphid‐specific Wolbachia protect against fungal pathogens

open access: yesEnvironmental Microbiology, Volume 26, Issue 11, November 2024.
Wolbachia infected more than 80% of Pentalonia aphids sampled across the Hawaiian Islands and other locations. The aphid‐specific M‐supergroup strains of this symbiont protected against a specialist fungal pathogen, Pandora, but not the generalist pathogen Beauveria or the parasitoid Aphidius colemanii.

A tale of three kingdoms: Members of the Phylum Nematoda independently acquired the detoxifying enzyme cyanase through horizontal gene transfer from plants and bacteria [PDF]

open access: yes, 2018
Horizontal gene transfer (HGT) has played an important role in the evolution of nematodes. Among candidate genes, cyanase, which is typically found only in plants, bacteria and fungi, is present in more than 35 members of the Phylum Nematoda, but absent ...

Different invasibility of permanent and temporary waterbodies in a semiarid Mediterranean Island [PDF]

open access: yes, 2019
Nonindigenous species (NIS) represent a threat to aquatic biodiversity worldwide. However, freshwater ecosystems in drylands are potentially more prone to biological invasions than those located in temperate regions because of the higher number of ...

Re‐evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 2

open access: yesEFSA Journal, Volume 22, Issue 11, November 2024.
Abstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish.

Marine sediment infauna‐based environmental assessment using metabarcoding identifies potential impact indicator species

open access: yesEnvironmental DNA, Volume 6, Issue 3, May–June 2024.
Intertidal infaunal community data are obtained via: (1) morphological identification of macroinvertebrates from sediment cores, (2) cytochrome c oxidase subunit I (COI) DNA metabarcoding of the same pooled macroinvertebrate specimens, and (3) 18S ribosomal RNA (18S) DNA metabarcoding of benthic meiofauna from small volume sediment surface scrapes.
