“…The opposite trend was observed for detritivore parasitoids, which increased in abundance with forest age in our research plots. Their host insects feed on mushrooms, carrion, dung, dead mollusks and other decaying materials (Wharton, 1984; Maeto, 1990b); therefore they are probably more abundant in old forests with greater forest floor litter mass (see also Hasegawa et al. , 2009 for the collembolan community).…”

1. To infer the effects of forest aging on the abundance, genus richness and diversity, and genus composition of understorey parasitoids, we investigated the assemblages of braconids collected in Malaise traps in a chronosequence of secondary broad-leaved forests (4-128 years old) in the satoyama landscape in the cooltemperate region of central Honshu, Japan.2. Multivariate linear regression analysis indicated that the abundance of braconid parasitoids was affected by forest age (time since clear-cutting) in the secondary broad-leaved forests, although the effects on genus richness and diversity were not statistically supported.3. The abundance of herbivore parasitoids decreased significantly with forest age. This is probably caused by the decline of insect herbivores associated with the decrease in forest floor vegetation along the chronosequence.4. The opposite trend was observed for detritivore parasitoids, which significantly increased in abundance with forest age, probably along with forest floor litter mass, though no significant change in the abundance of wood-borer parasitoids was observed with forest age.5. Genus composition of braconid parasitoids was affected by forest age, as determined by canonical correspondence analysis. Genera of detritivore parasitoids were mostly confined to older plots, those of herbivore parasitoids were rather abundant in younger plots, and those of wood-borer parasitoids were more broadly distributed.6. Therefore, we conclude that the presence of mixed forest stands of various age classes at the landscape level would contribute to the conservation of diverse assemblages of host insects and their parasitoids.

The paper considers blind species of the genus Folsomia having two pairs of macrosetae on both meso- and metathorax and united in so-called ‘inoculata’ group, which is given a new, more laconic definition. Morphological characters important in the group’s taxonomy are discussed and a further division into four subgroups is proposed. Eight new species, i.e., F. amurica Potapov & Kuznetsova, sp. n., F. breviseta Potapov & Kuznetsova, sp. n., F. calcarea Potapov, sp. n., F. imparis Potapov & Hasegawa, sp. n., F. laconica Potapov & Kuznetsova, sp. n., F. tertia Potapov, sp. n., F. trisensilla Potapov, sp. n., and F. tubulata Potapov & Babenko, sp. n., are described. F. hidakana Uchida & Tamura and F. inoculata Stach are redescribed basing on new material, for the latter species the Stach’s individuals were also examined. A key to species of the group is given.

“…The natural beech forest was characterized by a higher occurrence of Suctobelbidae, Enarthronota and Folsomia quadrioculata. All these groups are reported to be highly sensitive to disturbance (Hasegawa et al 2009;Maraun & Scheu 2000;Maraun et al 2003;Potapov 2001). Enarthronota produce only a few, slowly developing eggs and, despite their small size, they are assumed to be K-strategists (Maraun & Scheu 2000).…”

Spruce monoculture establishment affects functional traits of soil microarthropod communities

Structure and density of soil microarthropod communities (Oribatida and Collembola) were studied in one natural beech forest and one spruce monoculture planted on a former beech stand in South Bohemia (Czech Republic in the spruce monoculture for Collembola); additionally, it changed greatly the community structure in terms of species composition and functional traits. In the spruce monoculture, groups susceptible to disturbance were suppressed. The oribatid trophic structure changed as well with opportunistic herbifungivorous species increasing in the monoculture at the expense of fungivorous species. Similarly, hemiedaphic collembolans increased in the monoculture at the expense of euedaphic species. We conclude that the "functional approach" seems to be fruitful in revealing soil fauna response to environmental change.
