Strains of Vitreoscil/a stercoraria were isolated from the environment and characterised . Cell width, motility and requirement of each strain for sodium chloride were investigated. Two strains were selected for further study and the effect of monensin and FCCP on growth of the strains was investigated. One strain of Vitreoscil/a (l813) was chosen for further study, cells from strain LB 13 were...

This paper deals with some Collembola from a cave at La Sierra de Grazalema (Málaga). In total, eight species of springtails were found. Two may represent new but there is insufficient material available to prepare full descriptions (one in the genus Ceratophysella , one Hypogastrura ), (Folsomides cf. ayllonensis) identified species, differences nominal suggest further studies indicate populat...
