Influence of Temperature on the Physiology and Virulence of the Insect Pathogen Serratia sp. Strain SCBI [PDF]

open access: yes, 2012
The physiology of a newly recognized Serratia species, termed South African Caenorhabditis briggsae Isolate (SCBI), which is both a nematode mutualist and an insect pathogen, was investigated and compared to that of Serratia marcescens Db11, a broad-host-

Caenorhabditis monodelphis sp. n.: defining 1 the stem morphology 2 and genomics of the genus Caenorhabditis [PDF]

open access: yes, 2017
Background: The genus Caenorhabditis has been central to our understanding of metazoan biology. The best-known species, Caenorhabditis elegans, is but one member of a genus with around 50 known species, and knowledge of these species will place the ...

Natural variation of outcrossing in the hermaphroditic nematode Pristionchus pacificus [PDF]

open access: yes, 2009
Background Evolution of selfing can be associated with an increase in fixation of deleterious mutations, which in certain conditions can lead to species extinction.

Virulence of nematodes against larvae of the south-American fruit fly in laboratory using soil from Porto Amazonas, Paraná, Brazil, as substrate

open access: yesCiência Rural, 2015
: Anastrepha fraterculus is an important orchard pest. Its management has been based in chemical sprays, but biological control is a growing demand. The objective of this work was to evaluate, under laboratory conditions, the virulence of eight nematode

Evidence of hermaphroditism and sex ratio distortion in the fungal feeding nematode Bursaphelenchus okinawaensis [PDF]

open access: yes, 2014
Nematodes have many different reproductive strategies along with their divergent life-histories; the ability of hermaphrodite to self- and cross-fertilize is useful for genetic manipulation.

Complete Mitogenome of Cruznema tripartitum Confirms Highly Conserved Gene Arrangement within Family Rhabditidae

open access: yesJournal of Nematology, 2022
Mitochondrial genomes have widely been used as molecular markers in understanding the patterns and processes of nematode evolution. The species in genus Cruznema are free-living bacterivores as well as parasites of crickets and mollusks.

Robustness and evolution: concepts, insights and challenges from a developmental model system. [PDF]

open access: yes, 2006
International audienceRobustness, the persistence of an organismal trait under perturbations, is a ubiquitous property of complex living systems. We here discuss key concepts related to robustness with examples from vulva development in the nematode ...

Spontaneous mutation accumulation in multiple strains of the green alga, Chlamydomonas reinhardtii [PDF]

open access: yes, 2014
Estimates of mutational parameters, such as the average fitness effect of a new mutation and the rate at which new genetic variation for fitness is created by mutation, are important for the understanding of many biological processes. However, the causes

Oscheius microvilli n. sp. (Nematoda: Rhabditidae): A Facultatively Pathogenic Nematode from Chongming Island, China [PDF]

open access: yesJournal of Nematology, 2017
Abstract A new species, Oscheius microvilli n. sp., was found on Chongming Island (Shanghai, China). The new species is morphologically similar to the type strain of Oscheius myriophilus, but can be distinguished from it and other species of Oscheius on the basis of unique morphological characteristics of the bursa as well as male ...

Sex-specific lifespan and its evolution in nematodes [PDF]

open access: yes, 2017
Differences between sexes of the same species in lifespan and aging rate are widespread. While the proximal and evolutionary causes of aging are well researched, the factors that contribute to sex differences in these traits have been less studied.
