Compensatory growth of Phanerochaete velutina mycelial systems grazed by Folsomia candida (Collembola).
Phanerochaete velutina is a major agent of wood decomposition in temperate forests. It grows out of woody resources in search of other resources and is then vulnerable to grazing by invertebrates. The aim of this study was to determine how continuous grazing and grazing for only 2 days by different densities of collembola, Folsomia candida, affect mycelial development (radial extension, hyphal ...
متن کاملReorganization of mycelial networks of Phanerochaete velutina in response to new woody resources and collembola (Folsomia candida) grazing.
Mycelial development of Phanerochaete velutina extending from wood inocula in 57 x 57 cm trays of non-sterile soil was characterized after adding: (1) collembola; (2) new wood resources; (3) both new wood resources and collembola; and (4) no new resources and no collembola. After 99 d, all systems had produced distinct mycelial cords, much of the diffuse mycelium and thinner cords that were pro...
متن کاملAssessment of movement patterns in Folsomia candida (Hexapoda: Collembola) in the presence of food
24 25 We showed that Folsomia candida (a blind soil-dwelling Collembola) was able to shift from 26 non-directional (random or search strategy) to directional (target-oriented) movements at short 27 distance of food. We measured departure from linearity and access (or not) to food by the springtail 28 according to distance to the target position. Video-records and image analysis were used to obt...
متن کاملSpecies-specific impacts of collembola grazing on fungal foraging ecology
Fungi are primary agents of organic matter decomposition in forests. Although invertebrate grazing affects fungal biomass and morphology, the species-specific consequences of these interactions are little understood. Using three collembola species (Folsomia candida, Protaphorura armata, Proisotoma minuta) we employed a multi-trophic approach to investigate the individual effects of invertebrate...
متن کاملNew Method for Automatic Body Length Measurement of the Collembolan, Folsomia candida Willem 1902 (Insecta: Collembola)
The collembolan, Folsomia candida, is widely used in soil ecotoxicology. In recent years, growth rate of collembolans has become as frequently used endpoint as reproduction rate in ecotoxicological studies. However, measuring collembolan body sizes to estimate growth rate is a complicated and time-consuming task. Here we present a new image analysis method, which facilitates and accelerates the...
