The prevalence of the parasitic nematode Sphaerularia sp. in the overwintering gynes of Parapolybia spp. (Hymenoptera, Polistinae)

open access: yesJournal of Hymenoptera Research, 2014
I report for the first time the parasitization of overwintering gynes of Parapolybia species by the entomogenous nematode Sphaerularia sp. (Tylenchidae). The nematode was found in 42% of the overwintering wasp clusters examined but occurred in only 6% of

Testing for top‐down cascading effects in a biomass‐driven ecological network of soil invertebrates

open access: yesEcology and Evolution, Volume 10, Issue 14, Page 7062-7072, July 2020., 2020
Sketch of the empirical soil network used to simulate the cascading effects of guild removals in our prey–predator relationships. Abstract To investigate the structural changes of a food‐web architecture, we considered real data coming from a soil food web in one abandoned pasture with former low‐pressure agriculture management and we reproduced the ...

Trait-mediated diversification in nematode predator–prey systems [PDF]

open access: yes, 2011
Nematodes are presumably the most numerous Metazoans in terrestrial habitats. They are represented at all trophic levels and are known to respond to nutrient limitation, prey availability, and microbial resources.

Nematode migration and nutrient diffusion between vetch and barley material in soil [PDF]

open access: yes, 2007
This paper deals with migration of nematodes along nutrient gradients in soil. Portions of barley straw and green vetch leaves were mixed with soil and buried at 6, 12, 18, and 50mm distance from each other in soil.

Exploration and Selection of Penetration Site By Tylenchida

open access: yesNematologica, 1973
Filmed observations of eleven tylenchid species show the same basic pattern of behaviour leading to feeding. Simple sequences of behaviour initiated in response to stimuli lead to egg-hatching and host penetration. Searching behaviour, stimulated chemically by a host, includes locomotion, head movements and probing with the stylet; this is called ...

Transcriptome analysis of roots from resistant and susceptible rice varieties infected with Hirschmanniella mucronata

open access: yesFEBS Open Bio, Volume 9, Issue 11, Page 1968-1982, November 2019., 2019
This study investigated the mechanism of resistance to Hirschmanniella mucronata by comparing the transcriptomes of roots from resistant and susceptible varieties of rice. The results showed that the up‐regulated genes related to plant secondary metabolites may result in an increase in the degree of resistance to H.

Reduced tillage, but not organic matter input, increased nematode diversity and food web stability in European long‐term field experiments

open access: yesMolecular Ecology, Volume 28, Issue 22, Page 4987-5005, November 2019., 2019
Abstract Soil nematode communities and food web indices can inform about the complexity, nutrient flows and decomposition pathways of soil food webs, reflecting soil quality. Relative abundance of nematode feeding and life‐history groups are used for calculating food web indices, i.e., maturity index (MI), enrichment index (EI), structure index (SI ...
