This study investigates the response of soil fauna community to replacement beech by spruce or mixed stands and spruce. Stands different age were investigated in a factorial design with factors tree species (beech spruce) stand (30 120 yr). The input leaf/needle litter did not differ significantly between sites. By contrast, amount organic matter upper layers (L/F, H/Ah) forests strongly exceeded that particularly mature stands. increase was associated an microbial biomass. Biomass eight...
The relationships between species diversity and ecosystem functions are in the focus of recent ecological research. However, until now influence on processes such as decomposition or mineral cycling is not well understood. In deciduous forests, spiders an integral part forest floor food web. present study, patterns spider community structure related to stands Hainich National Park (Thuringia). 2005, pitfall trapping quantitative sampling were conducted nine plots with one (Diversity Level...
Different functional groups of generalist predators may complement each other in controlling prey populations; but intraguild interactions, common among predators, also reduce the strength top–down control. In natural communities greater alterations to ecosystem function are expected if a whole group declines abundance or is lost. Therefore studying diversity important for predicting effects predator loss. We studied impact web‐building spiders, hunting spiders and ants, which highly...
Abstract Ants are highly abundant generalist predators and important ecosystem engineers which can strongly affect the composition of animal communities. We manipulated density ant species Lasius niger with baits in a small‐scale field experiment to study role intraguild predation, top‐down control bottom‐up effects ants dry grassland surrounded by agricultural fields. Two different kinds (honey tuna) were presented near nests at distance 2 m from six L. colonies habitat, where was abundant,...
Abstract The interactions between ants ( Lasius niger ), aphids Aphis fabae ) and plants Phaseolus vulgaris were studied in a laboratory experiment with the following treatments: application of N‐fertilizer for plants, supply mealworms or sugar solution their combination as alternative food sources ants. Three main questions studied: (1) Do reduce tending to honeydew‐producing when an protein resource was available? (2) Is aphid predation/protein consumption by higher additional carbon is...
