... Their study, although limited in time and space, may be considered as a reference work, because of the extent of the thorough calculations that were made on the data matrix. Other recent studies have used multivariate analysis as a tool for delineating communities but unfortunately only on a small number of sites (Arbea & Jordana 1985 ;Pozo 1986;Mateos 1988). In the present discussion l will analyse results in the light of existing knowledge on Collembola n communities and tentatively trace the way in which these animaIs are sensitive to environmental influences . ...
... He registered differences in species composition in the litter, but examination of his graphs shows that these variations were mainly due to humidity and light, and not to vegetation. Mateos (1988) compared different soil types under the same dominant vegetation (Quercus ilex) and found differences in litter populations. As he used correspondence analysis too , sorne information can be gained from examination of his data. ...
... Differences between softwood and hardwood species were often attributed to vegetational influences (Cassagnau 1961;Szeptycki 1967;B6dvarsson 1973) but since the work of Gisin (1943) it has been established that humus type is a decisive factor in the establishment of soil Collembola communities. Other works showed that changes in soil conditions under the same tree species supported changes in species composition (Hagvar 1982;Hagvar & Abrahamsen In4;Mateos 1988) and our own research presents evidence that the way in which litter is decomposed is more important than the nature of the litter (Ponge 1980;Ponge & Prat 1982;Poursin & Ponge 1982;Ponge 1983;Poursin & Ponge 1984;Arpin et al. 1984;Arpin et al. 1986;Ponge et al. 1986). If we compare the results of the present study to those in the literature, there are many similarities. ...

Samples (679) from various forest sites in the atlantic temperate region (lowlands in the northern half of France) have been studied. Their Collembolan species composition 145 species, with only 43 rare species) was analysed by Benzecri's correspondence analysis, a multivariate method. Five groups of species, each associated with a given habitat, were determined: above the ground surface a distinction is evident between light species (open sites), hygrophilic species (moist forest sites) and corticolous species (dry forest sites); edaphic species may be divided into acidophilic species (mor, moder and acid mull humus) and neutroacidocline species (earthworm mull). A depth gradient may be traced from edaphic to atmobiotic species in both forest and open sites. As a conclusion, it is apparent that vegetation in itself does not directly influence Collembola but may effect them indirectly through humus formation.

Collembola (Hexapoda, Col/embola) associated with Basidiomycetes sporocarps in SW Catalonia. We have studied the collembola species found in basidiomata of 41 different species of fungi belonging to the Class Basidiomycetes, collected in several districts of the mediterranean SW Catalonia. We have found 5575 individuals of collembola of nine different species. Ceratophysella tergilobata represents the 99,8% of the total individuals and is present in the 94,8% of analysed basidiomata. In consequence this species must be considered an habitual inhabitant of the basidiomata of the mediterranean districts of Catalonia. The examination of the gut content of the studied collembola reveals that their relationship with the basidiomata is of nutritional type. RESUMEN. 'Se han estudiado las especies de colémbolos presentes en basidiomas de 41 especies distintas de hongos de la Clase Basidiomicetes, recolectadas en diferentes comarcas de la Cataluña mediterránea. Se han encontrado 5.575 ejemplares de colémbolos, pertenecientes a nueve especies. Ceratophysella tergilobata representa el 99,8% del total de ejemplares y está presente en el 94,8% de los basidiomas examinados, por lo que se considera un habitante habitual de las setas de las comarcas de la Cataluña mediterránea. El examen del contenido intestinal de los colémbolos estudiados revela que su relación con los cuerpos fructíferos de los hongos es de tipo nutricional.
