Collembola communities were studied in different agricultural habitats including intensively managed plant cultures, shelterbelts and grassy embankments in the area of the LAJTA Project. A total of 62 species were collected during the eleven-year study period (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012). Three species, namely Axenyllodes bayeri, Metaphorura denisi and Pseudosinella aelleni have proven to be new to the Hungarian fauna. Collembola species richness, abundance and diversity were the highest in shelterbelts, which shows their ecological role in agricultural environments. Grassy embankments are further important ecotone habitats that play significant role in soil fauna diversity and abundance. Intensively managed monocultures (maize, summer rape and winter wheat) were characterized by Collembola communities with low species richness and abundance.KULCSZAVAK: ugróvillás, agrárélőhely, szegély ökotonok KEY WORDS: Collembola, agrohabitat, edge ecotones BEVEZETÉSAz ugróvillások úgynevezett elsődlegesen szárnyatlan (Apterygota), belső szájszervű (Entognatha) rovarok. Régebben "ősrovaroknak", a mai "modern" rovarok ősének gondolták ezt a csoportot, de mostani tudásunk szerint inkább egy különálló fejlődési csoportot, a "Parainsecta"-t reprezentálják a hajnalrovarokkal (Protura) és a lábaspotrohúakkal (Diplura) közösen. Vizsgálatunkat a LAJTA Projecten belül nem az indokolja, hogy közvetlen kapcsolatban állnak az ottani szárnyas apróvad (pl. fogoly, fácán) állományaival, hanem az, hogy az ugróvillások a szárazföldi ökoszisztémák leggyakoribb rovarai (hivatkozás). Átlagos szabályként mondhatjuk, hogy zavartalan, természet közeli élőhelyeken ~1000 példányuk él minden liter földben (hivatkozás). A mezofauna tagjaként közvetett jelentőségük a fogolypopulációra éppen óriási egyedszámukból következik: nevezetesen a táplálkozási piramis alján, gyakorlatilag minden, a fogoly számára is fontos ragadozó ízeltlábúnak (farkaspókok, futóbogarak, százlábúak) zsákmányállatát képezik. Így biztosan állíthatjuk, hogy ahol gazdag ugróvillás-közösség él, ott gazdag macrofauna és bő táplálékkínálat van a rovarevő fajok számára is. Mindezen túl az ugróvillások tevékenysége a holt szerves anyag fogyasztása, lebontása, valamint a talajflóra megfelelő baktérium-gomba arányának kialakításában jelentős.

“…S. lewisi probably hunts a dominant species at each site and the collembolan species interacting with S. lewisi are different among sites. Furthermore, the densities and community structures of collembolans, tiny soil arthropods, are likely to be remarkably different among local points in one area; this depends on the environmental conditions of microhabitats, on soil conditions, on vegetation and on human disturbance (Bengtsson et al, 2000;Ponge et al, 2003;Sousa et al, 2004Sousa et al, , 2005Paul et al, 2011). The dominant species of collembolan groups may be different at the local points in a site; therefore, the prey-predator interactions between S. lewisi and collembolan groups appear to be different at the local population level.…”

1. Ants in the genus Strumigenys are predator ants that feed on tiny soil arthropods. The mandibles are modified into high‐speed traps to capture swift collembolan prey. The peculiar mandible morphologies of these ants have evolved depending on characteristics of the prey. Specifically, the evolution of mandible size and shape may be directly driven by prey size. 2. In the present study, the intraspecific variation of the morphological traits of Strumigenys lewisi populations were observed in central Japan. The relationships between the morphological variations and the prey body size were analysed. 3. In workers and queens, three morphological traits, head width, mandible length, and mandible width were significantly different among the multiple sites. Specifically, the mandible length was shorter in southwestern Japan than in other sampling locations. The ancova model revealed that the allometry of the mandible length to the head width was different among the sites. 4. As predicted, the mandible length was positively correlated with the average body size of collembolans in the Entomobryidae family. Furthermore, multiple regression analysis showed that the variation of the mandible length was affected by environmental factors represented as location information. However, the effect of collembolan body size was more effective at predicting mandible length. The study suggests that the geographical variation of mandible morphologies in S. lewisi has been selected by predator–prey interactions with collembolans.

“…Springtails (Hexapoda: Collembola) are an important and abundant soil microarthropod as interacts with ecosystem physiochemical processes, decomposing and mineralizing significant organic matter amount by the litterfall fragmentation and fecal production (Madej et al 2011, Ruggiero et al 2015. Moreover, the presence of springtails in soil is used for predicting and controlling primary decomposer actions such as bacteria and fungi and secondary decomposer actions such as nematodes and protozoa (Filser 2002, Petersen 2002, Jeffery et al 2010, Paul et al 2011, Chang et al 2013. Springtails are frequently abundant and sensitive to changes in the physical and chemical soil properties and natural micro-habitat characteristics after agricultural and forestry activities.…”

Morphological diversity of springtails (Hexapoda: Collembola) as soil quality bioindicators in land use systems

The aim of this work was to evaluate the soil quality of native forest, eucalyptus plantations, pasture, integrated crop-livestock, and no-tillage systems, correlating the morphological diversity of springtails with physical and chemical soil properties. Springtail samples were captured from soils of the southern plateau of the State of Santa Catarina in Brazil, during winter and summer, by using Pitfall traps, using a 3 × 3 point grid. The morphotyping of springtails consisted of the observation of five traits and for each one a partial value of the eco-morphological index was assigned to obtain the modified Soil Quality Index. A correlation of the morphotype abundance and diversity with physical (soil moisture, bulk density, biopores, microporosity, and macroporosity) and chemical (pH in water, calcium/magnesium ratio and total organic carbon content) soil properties was studied, describing all results by variance and multivariate analyses. The springtail abundance and diversity were influenced by the different land use systems. Higher soil quality index was determined in native forest followed by eucalyptus plantations, pasture, no-tillage system and integrated crop-livestock, in the winter. Moreover, higher soil quality index was found in native forest followed by integrated crop-livestock, eucalyptus plantations, no-tillage system and pasture, in the summer. Therefore, the quality index of a soil can be evaluated by the springtail morphological traits in correlation with the physical and chemical properties such as calcium/magnesium ratio, total organic carbon contents, biopores, macroporosity, microporosity, soil moisture, bulky density and pH.
