Effects of disturbance frequency on canopy age structure and species composition in a managed Midwestern oak savanna
  • Effects of disturbance frequency on canopy age structure and species composition in a managed Midwestern oak savanna
  • Biogeography ; Dendrochronology ; Fire ; Forestry ; Oak ; Rehabilitation ; Savanna ; United States of America ; Vegetation dynamics ; Wisconsin
  • In this study, the A. focused on documenting the size and age distribution of oaks, and the density and diversity of all tree species. The questions addressed were : what is the relationship between age and size patterns of oak regeneration under
  • different management regimes ? Do these management regimes help to maintain oak dominance and diversity of associated species ?
Subboreal « black oaks » identified from the Vistula alluvia at Grabie near Cracow-South Poland)

  • Cracow ; Dendrochronology ; Dendrology ; Fluvial deposit ; Fluvial processes ; Oak ; Poland ; Sedimentology ; Valley ; Wisła
  • Detail geological and dendrochronological study of the Grabie gravel pit is presented. This site illustrates the existence of age differences between the alluvia (19 c.) and the inserted black oaks with dates cf c. 3 000 BP. The fall of tree trunks
  • may be related to the phase of increased activity of the Vistula 3 200- 3 000 BP. The black oaks (Quercus velutina) from Grabie have an evidence of mechanical damage connected with the ice-jam floods. - (DG)
Wind deposition of mud aggregates and their role in development of lamellae in the Fair Oaks Dunes, Indiana
  • Wind deposition of mud aggregates and their role in development of lamellae in the Fair Oaks Dunes, Indiana
  • Three parabolic dunes from the Fair Oaks Dune field in northern Indiana were excavated, in order to study the properties and genesis of lamellae. In this paper, the AA. demonstrate petrogenic (depositional) origin of these lamellae.

Soil evolution in the remnants of natural forest vegetation : an example from an old oak-lime coppice wood in Denmark
  • Soil evolution in the remnants of natural forest vegetation : an example from an old oak-lime coppice wood in Denmark
  • A mixed Quercus-Tilia forest was investigated to study the soil development in a forest that resembled the natural Danish forest composition before 4000 BC. The results indicate that the oak-lime type of forest prevents or retards podzolization
Heterogeneity in soil hydrological response from different land cover types in southern Spain
  • This paper reports results from the analysis of the soil hydrological response to simulated rainfalls in a cork oak forest in Los Alcornocales Natural Park (SW Spain). Marked differences in the hydrological behavior of the studied vegetation types
  • (cork oak forest, heathland, grassland, and forest of mixed cork oak and olive tree) were observed after the rainfall simulations. The mosaic of different patterns of hydrological response to rainfall, such as runoff generation or infiltration
Seismic facies and regional architecture of the Oak Ridges Moraine area, Southern Ontario
  • Seismic facies and regional architecture of the Oak Ridges Moraine area, Southern Ontario
  • L'analyse de 50 km de profils de sismique réflexion terrestre à haute résolution ont permis une observation de l'architecture sédimentaire de subsurface et de la relation entre les unités stratigraphiques glaciaires en-dessous de la moraine de l'Oak
