Genetic Analysis of Pinus sylvestris L. and Pinus sylvestris forma turfosa L. Using RAPD Markers
Notulae Scientia Biologicae, 2010 The purpose of the present study was to determine the level of genetic diversity within and among Ciuc basin, Romania (populations from Mohos and Luci raised bogs in Harghita Mountain and Sumuleu in Ciuc Mountain) Pinus sylvestris populations using ...

Boreas, EarlyView.Our knowledge of the Early Upper Palaeolithic occupation in northern central Europe is very limited, and recent research at the open‐air site of Friedrichsdorf‐Seulberg in Hesse, Germany, provides important new information on the Aurignacian. The site is rather small (26.5 m2) and spatial analysis identified a central hearth with two associated ...

Variability of photosynthetic capacity and water relations of Pinus sylvestris L. in the field
, 2011 Measurements of dependence of photosynthetic electron transport on irradiance and analyses of stable isotope ratios (δ18O, δ13C, δ15N) were performed on 4 to 6-year-old pine trees (Pinus sylvestris L.) in the primeval forest reserve of Białowieża and on ...

Boreas, EarlyView.Land snail successions in the lower Rhône valley allow us to reconstruct the postglacial recolonization. From the Lateglacial period onwards, Mediterranean steppe communities appeared. The arrival of forest taxa was significantly delayed by aridity. The question of glacial refugia, both local and distant, primarily concerned Mediterranean species of ...

Ethylene and auxin in the control of wood formation [PDF]
, 2003 This thesis considers aspects of the regulation of growth rate and fibre properties in forest trees. These properties are both genetically determined and influenced by environmental stimuli.

Boreas, EarlyView.A long‐term perspective on landscape evolution is critical for understanding past land‐use activity, land cover–climate feedbacks and, notably, for establishing a factual basis for conservation. Fossil pollen analysis provides a means to achieve this. Biases pertaining to pollen productivity, pollination processes and basin size, however, mean there is

Ecological Entomology, EarlyView.Forest management and climate‐induced tree dieback alter the structural characteristics of forests, which could subsequently lead to changes in the structure of beetle assemblages. Beetle assemblages in more open forests exhibited less even abundance distributions, with fewer, more dominant species (higher rates of decline (r), higher dominance (d ...

Insect Conservation and Diversity, EarlyView.Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers
