Mutualistic Relationship

The first observations of the aphid Prociphilus fraxini (Fabricius, 1777) being involved in a mutualistic relationship with the ant Prenolepis nitens (Mayr, 1853) in Europe is documented. Mutualism of an aphid generation living with the ants Prenolepis nitens and Lasius brunneus (Latreille, 1798) is discussed in reference to the possible development of an overwintering parthenogenetic population of the aphid, persisting on the roots of its secondary host, Picea abies, due to coevolution of the aphid with ants.

Insight Into

A study aiming at the description of invertebrate fauna trapped in contemporary, coniferous resins was undertaken in a mixed forest of Central Europe (Southern Poland). Resins were collected predominately from spruce (Picea abies), but also from pine (Pinus sylvestris) and larch (Larix decidua), the cadavers were extracted from the ethanol solution of resin. As many as 394 specimens were extracted, consisting mainly of insects, but also arachnids, crustaceans and single mollusc were found. Among the collected specimens, some were identified to species, and a few mutual, ecological interrelationships could be traced. Although the amount of collected resins is far from being comparable with the amount of particular types of amber studied in the world so far, the Discussion focuses on similarities and differences in insect inclusions composition in resins and known amber collections.

Temperature Records

The tree-ring width and the maximum wood density of Norway spruce (Picea abies (L.) Karst.) have been examined in order to reconstruct air temperature of the summer half-year during the period 1804 - 1989. The trees examined come from a natural spruce stand of Labský důl (Elbe Valley) in Krkonoše (Giant Mts.), North Bohemia. The results obtained by this way have been compared with a similar reconstruction made for Central Europe and with air temperature records from the Prague-Klementinum station. Both temperature series (reconstructed and measured), however, show only 36 % of commonly clarified variability. Differences may follow from the standardization of dendrochronologies as well as from other factors which may have influenced the growth of spruce. The quality of air temperature measurement may play also role.

Ditiola haasii, a largely unknown member of the Dacrymycetes described from Germany, is documented in detail based on two specimens collected on Picea abies wood in the Boubínský prales virgin forest, Czech Republic. The work represents the first complete taxonomic/ecological investigation of the species since its original description. The morphology of the newly studied samples is evaluated to gain a better knowledge of intraspecific variation, and a phylogenetic analysis based on nrLSU data is provided to further confirm our identification and show the phylogenetic position of D. haasii within the Dacrymycetes. A comparison with similar species and those with which it has been confused is made and ecological details are provided based on our collections. Colour photographs of basidiomata and micromorphological characters are published. Ditiola haasii is currently documented by just six records worldwide, all of them from Central Europe.

Abstract We found ubiquitous evidence of ongoing slope instability by analysing the variability of tree-ring eccentricity index in trees growing on three apparently relict landslide slopes in the Sudetes (Poland, Central Europe). Slow movement of these landslide bodies occurs in the present-day conditions and is recorded almost every year, although with variable intensity. Correlation of dendrochronological record with the rainfall record from a nearby station in Mieroszów for the 1977–2007 period is very poor for two deep-seated rotational slides at Mt Suchawa and Mt Turzyna but considerably better for a shallow flowslide at Mt Garbatka. While this may reflect higher permeability of heavily jointed rocks involved in deep-seated sliding this could be linked with imperfections in the rainfall record. Dendrochronology proved capable of detecting minor displacements within landslides which otherwise show no geomorphic evidence of recent activity. Therefore, claims for the entirely relict nature of the landslides are not substantiated.
