  • Climatic response in tree rings of loblolly pine from north Georgia
  • The relationship between climate and tree-growth for loblolly pine in north Georgia is investigated by : 1) determining during which months climate has its strongest impact on loblolly pine growth, and 2) specifically examining the relationship
  • between loblolly pine growth and growing season precipitation. The results indicate that loblolly pine is a useful species for investigating the impact of climate and other factors on the recent decline of pine growth in the southeastern United States.
  • Effects of ice storms, southern pine beetle infestation, and fire on Table Mountain pine forests of southwestern Virginia
  • Aridity ; Biogenic process ; Biogeography ; Forest ; Forest fire ; Mountain ; Pine ; Population dynamics ; Twentieth Century ; United States of America ; Virginia
  • The AA. investigated Table Mountain pine stands growing on dry, west facing slopes in southwestern Virginia. In stands the AA. sampled most Table Mountain pines belonged to a cohort that originated in the early 1900s, probably following a severe
  • burn. Recent disturbances changed the stands considerably : ice storms, pine beetle infestation. These disturbances stimulated little pine regeneration. The results suggest that without fire, long-term maintenace of Table Mountain pine is improbable.
  • The role of vegetation dynamics in Choctawhatchee sand pine invasion of longleaf pine forests

  • Expansion of sand pine on the Florida Panhandle started by 1920, but rapidly increased in the 1940s. Population establishment and growth in invasive stands has been rapid, with establishment of many sand pine pioneer individuals followed by rapid
  • infilling as these individuals reached reproductive maturity. Analyses of hemispherical canopy photographs and regeneration patterns illustrate the ability of sand pine to establish under a variety of light conditions. Radial growth analysis of incremental
  • tree cores highlights the importance of episodic wind disturbances in maintaining these sand pine populations.
  • Ecosystem process studies along a climatic transect at 52-53°N (12-32°E) : pine litter decomposition
  • Central Europe ; Climatic variation ; Continentality ; Ecosystem ; Europe ; Evapotranspiration ; Forest ; Litter ; Pine ; Precipitation ; Statistical analysis ; Temperature
  • The response of litter decomposition to changing climate was studied on a transect set in Central Europe along parallel 52°N. Rates of decomposition of pine forest litter were measured for one year in 15 stands of Scots pine (Pinus sylvestris) along
  • on pure stands of Scots pine, significantly faster on mixed pine stands and fatest on anthropogenically-modified pine stands.
  • Human influences on the pine and laurel forests of the Canary Islands
  • White sand and blue pines : a nostalgic landscape of Japan
  • Coastal environment ; Cultural landscape ; Japan ; Landscape ; Landscape esthetics ; Pine ; Sand
  • Japanese are said to have a sentimental nostalgia for the Hakusha-seisho : the white sand beach with dark green pine trees. The A. analyzes the origin and meaning of this ladnscape that is a result of the human transformation of nature. In modern
  • Pine forests in Poland. Their productivity, distribution and degradation
  • The information on the biomass, productivity and distribution of pine forest is compared to the distribution of air pollution with sulfur.
  • Palaeoecology of pine (Pinus sylvestris) in the Swedish Scandes and a review of the analysis of subfossil wood
  • Dendrochronology ; Holocene ; Mountain ; Palaeo-ecology ; Palaeo-environment ; Pine ; Quaternary ; Sweden ; Tree line
  • Subfossil pine (Pinus sylvestris L.) occurs in various deposits and in great freqency well above the current altitudinal pine limit in the Scandes Mountains. These tree remnants constitute a fairly continuous record of range-limit dynamics
  • Edaphic properties and foliar elemental concentrations from sand pine (Pinus clausa) populations throughout Florida
  • Biogeography ; Ecosystem ; Florida ; Geochemistry ; Nutrient ; Pedogenesis ; Pine ; Soil ; Soil properties ; Spatial variation ; United States of America ; Vegetation
  • This study examines soil physical and chemical properties and measures the concentration of a suite of soil and foliar tissue elements from sand pine (Pinus clausa) populations scattered throughout Florida. The AA. document significant
  • bioconcentration of nutrients in sand pine foliage and compare observed foliar nutrient concentrations with those typical of other southern pines. They test for systematic differences in soil and foliar elemental concentrations associated with both varietal
  • Structural variation and dynamics of lodgepole pine forests in Lassen Volcanic National Park, California
  • Biogeography ; California ; Climatic variability ; Forest ; Microclimate ; National park ; Pine ; Soil properties ; United States ; Vegetation dynamics
  • Diameter structure, age/diameter regressions, and stem dispersion patterns reveal spatial variability in lodgepole pine forest structure and dynamics in Lassen Volcanic National Park (LVNP). Spatial variability in this early successional species
  • Structural dynamics of a Southwestern pine forest under chronic human influence

  • The paper examines the impact of several synchronous disturbances, both natural and anthropogenic on the development of the Navajo ponderosa pine forest in the Chuska Mountains of the American Southwest during the fast several hundred years
  • Determining the optimal spatial resolution of remotely sensed data for the detection of sirex noctilio infestations in pine plantations in KwaZulu-Natal, South Africa
  • Biogeography ; Disease ; Forestry ; KwaZulu-Natal ; Phytogeography ; Pine ; Remote sensing ; South Africa
  • Sirex noctilio is causing considerable mortality in commercial pine plantations in KwaZulu-Natal. The ability to detect variable infestation levels by remote sensing remains crucial for monitoring the spread of the disease and for effective
  • Holocene pollen history of the Alta area, an isolated pine forest north of the general pine forest region in Fennoscandia
  • A 8000years old pine trunk from Dovre, South Norway
  • A well preserved pine trunk, 3-4m long and 0,3m thick, sticking out of a bog situated about 1010m above sea-level, in the now almost treeless area above Nysetra on the Dovre plateau, has been dated at 8240100years B. P. This great age corresponds
  • well with the results obtained from other regions in Norway and also the Sylarna-Ovik mountains in Sweden, showing that pine reached its highest post-Weichselian altitude and widest distribution just before 8000 B. P. (IMB).

  • Mountain pine radial growth and the forest limit zone in Gadmental, Swiss Alps
  • The impact of grazing on spatial variability of humus profile properties in a grass-encroached Scots pine ecosystem
  • Ecosystem ; Humus ; Netherlands (The) ; Organic materials ; Over-grazing ; Pine ; Sampling ; Soil erosion ; Soil properties ; Spatial variation
  • Grazing is often used in management of grass-encroached Scots pine (Pinus sylvestris) forests in The Netherlands, because it is thought to increase diversity of vegetation and humus profiles. To test this hypothesis, two 1 ha plots in a primary pine
