“…This also explains the parallel increase of collembolan biomass, since the body size of springtails is systematically related to their life form (epedaphic > hemiedaphic > euedaphic; cf. Petersen 2002). The fact that some epedaphic species invaded the clear-cut area proves the high dispersal ability of those species stressed by various authors (Greenslade and Majer 1993;Ojala and Huhta 2001).…”

“…In a previous study we highlighted the importance of Oribatid mites as a component of the buffering mechanisms of spruce forests against environmental changes (Zaitsev et al 2002). However Oribatids are slow-responding K-strategists (Walter and Proctor 1999), while Collembola, another mesofauna group, are generally assumed to follow an r-strategy (Petersen 2002) and rapidly respond to environmental changes (Butcher et al 1971;Dunger 1975;Kaczmarek 1975;Hågvar 1982;Ponge 1983Ponge , 1993Klironomos and Kendrick 1995). The ecological role of Collembola during forestry cycles might therefore be considerably different from that of Oribatida.…”

Successional changes of Collembola and soil microbiota during forest rotation

Dynamic approaches to forest ecosystems are surprisingly rare. Here we report about successional changes in collembolan community structure and microbial performances during forest rotation. The study was carried out in a chronosequence of four spruce forest stands (5-, 25-, 45-, and 95 years old; Tharandter forest, Germany). CO2 release significantly increased after clear-cutting and the amount of C stored in the organic layer subsequently declined. The early phase of forest rotation was characterized by a very active decomposer microflora, stimulation of both fungi and bacteria as well as by a high abundance of surface-oriented Collembola. In addition, collembolan species turnover was accelerated. While the biomass of fungi further increased at intermediate stages of forest rotation, the metabolic activity of the microflora was low, the functional diversity of bacteria declined and the collembolan community became impoverished. Euedaphic species dominated during this stage of forest development. These changes can be explained by both reduction in microhabitat diversity and depletion of food sources associated with an accumulation of recalcitrant soil organic matter. Results of the General Regression Model procedure indicate a shift from specific associations between collembolan functional groups and microbiota at the early stage of forest rotation to a more diffuse pattern at intermediate stages. Though the hypothesis that Collembola are relatively responsive to changes in environmental conditions is confirmed, consistently high community similarity suggests a remarkable persistence of some components of microarthropod assemblages. Our study provides evidence for substantial ecosystem-level implications of changes in the soil food web during forest rotation. Moreover, correlations between bacterial parameters and Collembola point to the overarching impact of differences in the composition of the microbial community on microarthropods.

“…It is important to adopt tillage methods which promote the highest possible yield while causing minimum damage to microorganisms and fauna in the soil (Petersen, 2002b) and also find properties that indicate changes in soil quality as a result of the uses adopted. Few studies have worked with the possibility of using EM groups of springtails as indicators of the effects of soil use (Parisi, 2001;Parisi et al, 2005;Vandewalle et al, 2010).…”

“…Los colémbolos, dentro de los microartrópodos, son unos de los organismos más abundantes en el ecosistema suelo (Hopkin, 1997;Petersen, 2002). Estos organismos son considerados generalistas debido a que su dieta se compone de una mezcla de detritos, algas, bacterias y hongos (Hopkin, 1997;Scheu y Folger, 2004), y debido a su actividad alimentaria, afectan tanto a la microestructura como al proceso de descomposición de los residuos en el suelo (Seastedt, 1984;Cragg y Bardgett, 2001;Fountain y Hopkin, 2005).…”

<p>El objetivo del trabajo fue determinar los efectos letales y subletales de metaldehído y/o carbaril sobre Folsomia candida. Se realizaron tres bioensayos bajo un diseño completamente aleatorizado con cuatro repeticiones y en condiciones controladas (20 ± 2 ºC y 14L:10O). La unidad experimental fue un recipiente (9,3 cm de diámetro y 6,4 cm de altura) donde se colocaron 60 g de suelo mezclado con las dosis del cebo y 10 individuos adultos (2 a 3 mm de longitud). Los tratamientos fueron: 0, 40, 80, 120, 160 y 200 g de ingrediente activo (IA) ha-1 de metaldehído; 0, 80, 160, 240, 320 y 400 g IA ha-1 de carbaril; y 0, 40+80, 80+160, 120+240, 160+320 y 200+400 g IA ha-1 de metaldehído+carbaril. Con metaldehído tanto la proporción de individuos vivos como el número de crías no difirieron entre los tratamientos a los 7, 14, 21 y 28 días después de la aplicación (DDA) (p> 0,05). Las dosis mayores de carbaril y metaldehído+carbaril ocasionaron disminuciones en la proporción de individuos vivos y en el número de crías a los 28 DDA (p< 0,05). Los cebos que contienen carbaril causaron mortalidad y disminución en el número de crías de F. candida.</p>
