Abstract As the most abundant animals on earth, nematodes are a dominant component of soil community. They play critical roles in regulating biogeochemical cycles and vegetation dynamics within across landscapes an indicator biological activity. Here, we present comprehensive global dataset nematode abundance functional group composition. This includes 6,825 georeferenced samples from all continents biomes. For geospatial mapping purposes these aggregated into 1,933 unique 1-km pixels, each...
The article describes the communities of soil nematodes in pine (hereinafter -Pinus sylvestris) and spruce -Picea abies) forests Finnish-Russian Friendship Nature Reserve.It exemplifies typical northtaiga combines Kostomuksha State Reserve (Republic Karelia, Russia) Park, consisting five Protected Areas adjacent area Finland.Methods commonly applied nematology were used to study following parameters: taxonomic diversity, population density, biomass, eco-trophic structure nematode...
The effect of crops cultivation on the soil free-living and plant-parasitic nematodes in agrocenoses southern Karelia (fields with tilled crops, artificial grasslands) was studied. A comparison monodominant plant communities (tilled crops) cenoses alien species Heracleum sosnowskyi Manden made. characteristics reflecting features nematode different types were established. They include faunal composition identification constant specific taxa determining similarity/differences between...
The article presents the first data on nematode communities inhabiting soil under hogweed thickets ( Heracleum sosnowskyi Manden.) in Karelia, Leningrad and Moscow districts. Comparison of parameters four habitats located 55° to 61° N allowed describing effect geographical latitude with plant-invader nematodes for European part Russia. Parameters were following: taxonomic diversity, abundance, eco-trophic structure. It was revealed that abundance diversity greatly varied high locality;...
The study was aimed on the assessment of extracts from two arctic brown seaweeds Ascophyllum nodosum and Laminaria digitata as biological nematicides against phytoparasitic nematodes. Potato cyst-forming nematode Globodera rostochiensis Woll. used test organism. Seaweed were got Arkhangelsk Factory LLC. Extracts A. L. have been experimentally shown to nematicidal properties dangerous potato pest G. . addition seaweed root diffusates slowed down juvenile hatching process, affected contents...
Soil nematode communities of coniferous and deciduous forests in protected areas the Republic Karelia were studied with regard to their latitudinal position. A series parameters (taxonomic diversity, population density, eco-trophic structure ecological indices soil food web) used assess communities. The highest taxonomic diversity was observed linden lowest one soils pine forests. Bacterial-, fungal feeders nematodes associated plants dominated community all types forest biocoenoses....
Influence of zinc and lead salts on taxonomic diversity population characteristics (population density, seasonal dynamics, age eco-trophic structure) nematodes-phytotrophs was experimentally studied. Parameters, sensitive resistant to heavy metals, were detected. Taxonomic composition nematodes found decrease in metal treatments some terms observations. The most considerable changes revealed for total number nematodes-phytotrophs. After applying metals into the soil (May – June) increased,...
