Abstract (sommario):

The biodiversity of soil-inhabiting nematodes in Canada is incompletely known, as large areas of Canada’s landmass have not been surveyed for nematode fauna. Nematodes considered as indigenous are generally well adapted to a variety of ecological niches and climatic zones. Much of the available information is based on agricultural ecosystems and agricultural species, and thus is biased toward conditions in disturbed ecosystems and away from “primeval” ecology. Introduced nematode species are frequently quite pathogenic, even to exotic host plants from the same geographic point of origin. Estim

Abstract (sommario):

Nematodes play a key role in ecological environments. Biotic indices based on soil nematode community are effectively used for assessing soil health status. This work represents the opportunity to investigate three different management practices continuously maintained for 40 or more decades on soils with the same geological origin. This unique feature allows us to reduce variables and link biotic with abiotic factors. Therefore, the nematode communities of three neighboring volcanic soils under different managements were examined. The maximum values in soil biodiversity were found in the fore

Soil biodiversity plays a critical role in supporting multiple ecosystem functions.

Taking advantage of an investigation on Huangshan Mountain, Southeast China, with elevation ranging from 500 to 1200 m, we assessed the abundance and diversity of soil nematodes, as well as the soil physicochemical properties, across subtropical

In this study, we explored the impact of two classes of common soil macrofauna, earthworms (Eisenia foetida) and millipedes (Spirobolus walkeri), on soil nematode community diversity and structure. We found that earthworms and millipedes play an important role in maintaining soil nematode communities and increasing soil nutrients. Both earthworms and millipedes ac

Abstract (sommario):

Microplastics (MPs), defined as plastic particles of less than 5 mm, pose a significant global environmental threat, particularly in aquatic ecosystems, due to their persistence and potential harmful effects on wildlife and human health. They can absorb persistent organic pollutants (POPs), like polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), raising concerns about their impact on biota. To elucidate this impact, the present study employed attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) to analyse the characteristics of MPs sourced

Abstract (sommario):

Nitrogen deposition has a significant impact on biodiversity and ecosystem functions. However, various mechanisms by which nitrogen deposition affects soil nematode communities in nitrogen-limited temperate forests remain unclear. We conducted long-term nitrogen deposition simulation experiments (including two treatments, control and 50 kg N ha⁻1 yr⁻1) in the Lesser Khingan Range, Greater Khingan Range, and Changbai Mountain, applying nitrogen fertilizer solutions to investigate the effects of long-term nitrogen addition on soil nematode communities in northeastern Chinese forests.

Abstract (sommario):

Summary Dokdo Island has a unique biodiversity that has been preserved as a natural monument. Although the biodiversity of Dokdo has been investigated, little information is available regarding the nematodes. The diversity of plant-parasitic nematodes was investigated using both ITS and D2-D3 sequences. Nematodes extracted from 59 rhizosphere soil samples were morphologically identified as belonging to eight genera: Geocenamus, Helicotylenchus, Rotylenchulus, Heterodera, Paratylenchus, Pratylenchus, Pratylenchoides and Xiphinema. Further, nucleotide sequences were determined from 85 individual

Abstract (sommario):

Background Nematodes are among the most diverse and abundant metazoans in aquatic habitats, contributing significantly to global biodiversity. Despite their abundance and importance, the presumed number of undescribed species is high and their diversity is often underestimated. Methods In this research, sediment samples were collected from three microhabitats (bare sand, seagrass, coral) in two sites around Okinawa-jima Island in subtropical southern Japan. Nematode specimens were obtained by filtering the sediment and were then used to determine meiofaunal assemblages with morphology and mole

All investigated faunal variables differed significantly between impact and control sediments, except for indi- vidual nematode biomass.

Free-living aquatic nematodes are abundant, diverse and of general environmental importance. However, knowledge of species distributions of both marine and freshwater nematodes is sparse. Species distribution data are crucial for evaluating environmental impacts from human activities and to conduct integrated nematode community assessments. Basic knowledge on taxonomy and species descriptions is lacking for many regions due to decreasing taxonomic expertise, yet it is essential for biodiversity research and for building molecular sequence libraries for the application of methods such as enviro

AbstractDespite their potential negative effects, parasites may be used as targets for biological conservation and studies on the evolutionary and ecological impact of parasitism. These purposes serve to increase our knowledge on the species diversity of parasites. In the present paper we try to precisely define the composite zoological group currently designated as 'helminths' and to address the question of how many known species there are in the different clades of parasitic worms, as compared with the other major groups described in the Animalia.

Nematodes were the dominant group as is common in brackish water systems. The nematode community was made up of 62 genera in 22 families.

Abstract (sommario):

AbstractPractitioners of nematode taxonomy have rarely been explicit about what species represent or how data are being used to delimit species prior to their description. This lack of explicitness reflects the broader species problem common to all biology: there is no universally accepted idea of what species are and, as a consequence, scientists disagree on how to go about finding species in nature. However, like other biologists, nematologists seem to agree that species are real and discrete units in nature, and that they result from descent with modification. This evolutionary perspective
