Why are nematodes so successful extremophiles?

  • 2021
TLDR
It is proposed that a unique combination of several characteristics of nematodes may explain, additively or synergistically, their successful adaptation to extreme habitats.
Tokorhabditis n. gen. (Rhabditida, Rhabditidae), a comparative nematode model for extremophilic living
TLDR
The description of the new genus Tokorhabditis tufae reveals that the origin of this uncommon reproductive mode is even more ancient than previously assumed, and it presents a new comparator for the study of mating-system transitions.
Nematode epibionts on skin of the Florida manatee, Trichechus manatus latirostris
TLDR
No skin lesions were observed during the 2018–2019 samplings suggesting that under normal conditions these nematodes are highly specialized free-living epibionts of the skin that are tightly bound to this niche and horizontally transferred between individual manatees in an analogous fashion to human skin mites.
Genome-Wide Transcriptional Responses of Marine Nematode Litoditis marina to Hyposaline and Hypersaline Stresses
TLDR
This study investigated marine animal’s genome-wide transcriptional responses to salinity stresses using an emerging marine nematode model Litoditis marina and found that the transthyretin-like family genes were significantly increased in both hyposaline and hypersaline conditions, suggesting the existence of conserved strategies for response to stressful salinity environments in L. marina.
Reproductive plasticity in response to food source in the fungal-feeding nematode Bursaphelenchus okinawaensis
TLDR
This study provided an insight into a novel type of phenotypic plasticity in nematodes, showing that the hermaphrodite or female status of SH3 nematode was a plastic character, dependent on the food stimulus.
Evolution and Developmental System Drift in the Endoderm Gene Regulatory Network of Caenorhabditis and Other Nematodes
TLDR
This short review will explore how genetic variation in the endoderm GRN helps to drive DSD at both inter- and intraspecies levels, thereby resulting in a robust developmental system.
Trace Elements in the Bottom Sediments of the Crimean Saline Lakes. Is It Possible to Explain Their Concentration Variability?
Knowledge of trace elements content and their behavior in aquatic ecosystems is important for their sustainable use. There is a lack of such data for saline and, especially, hypersaline lakes and…
Fisher vs. the Worms: Extraordinary Sex Ratios in Nematodes and the Mechanisms that Produce Them
TLDR
Recent research in nematodes that has characterized the mechanisms underlying highly skewed sex ratios in fully diploid systems are discussed, including self-fertile hermaphroditism and the adaptive elimination of sperm competition factors, facultative parthenogenesis, non-Mendelian meiotic oddities involving the sex chromosomes, and environmental sex determination.
First record of a mermithid nematode (Nematoda: Mermithidae) parasitizing winged females of gall-forming aphids (Hemiptera: Aphididae: Eriosomatinae)
TLDR
It is indicated that mermithid parasitism of sexuparae led to fewer and smaller sexual female embryos.

Microsporidia-nematode associations in methane seeps reveal basal fungal parasitism in the deep sea
TLDR
It is revealed that methane seeps support complex ecosystems involving interkingdom interactions between bacteria, nematodes, and parasitic fungi and that microsporidia parasitism exists also in the deep-sea biosphere.
A molecular evolutionary framework for the phylum Nematoda
TLDR
It is suggested that animal parasitism arose independently at least four times, and plant parasitism three times, which indicates that convergent morphological evolution may be extensive and that present higher-level classification of the Nematoda will need revision.
The evolution of parasitism in Nematoda
TLDR
Nematode genomes show evidence of horizontal gene transfer from other members of the rhizosphere, and these genes play important roles in the parasite-host interface, but similar horizontal transfer is not evident in animal parasitic groups.
Nematoda from the terrestrial deep subsurface of South Africa
Since its discovery over two decades ago, the deep subsurface biosphere has been considered to be the realm of single-cell organisms, extending over three kilometres into the Earth’s crust and…
Soil Nematodes and Desiccation Survival in the Extreme Arid Environment of the Antarctic Dry Valleys1
  • A. Treonis, D. Wall
  • Environmental Science, Medicine
    Integrative and comparative biology
  • 2005
TLDR
The coiled morphology of nematodes extracted from dry valley soils suggests that they employ anhydrobiosis, and these coiled nematode showed enhanced revival when re-hydrated in water as compared to vermiform nematoda, which represents an important temporal component of a dry valley Nematode's life span.

Survival of intracellular freezing by the Antarctic nematode Panagrolaimus davidi
  • Wharton, Ferns
  • Biology
    The Journal of experimental biology
  • 1995
TLDR
Determining the mechanisms by which this nematode survives intracellular freezing could have important applications in the cryopreservation of a variety of biological materials.
Meiobenthos at the Arctic Håkon Mosby Mud Volcano, with a parental-caring nematode thriving in sulphide-rich sediments
Hakon Mosby Mud Volcano (HMMV, SW Barents Sea slope, 1280 m) is one of the numerous cold methane-venting seeps existing along the continental margins. Analyses of video- guided core samples revealed…

Factors determining nematode distributions at Cape Hallett and Gondwana station, Antarctica
TLDR
The distribution of nematodes at Cape Hallett and Gondwana station was found to be patchy but consistent, broad-scale habitat preferences were identified, indicating that habitat preferences are consistent across large scales and may play a role in determining range limits.
