This study aims to determine the composition and structure of sapling strata plants in Silokek Geopark Area, Sijunjung Regency. Vegetation analysis was carried out using transect method with a plot size 5 x m. 10 plots were made identification unknown plant species at Andalas University Herbarium. Based on research results found 31 consisting 48 individuals 14 families. The co-dominant families...
Indonesia is a biodiversity-rich country with the second-largest tropical forest in world. One East Kalimantan Forest area focus Hemaq Beniung Customary Forest. The first customary its license granted by Ministry of Environment and Forestry Republic Indonesia. Information on vegetation diversity essential to ensure sustainable management this area. This research provides such information throug...
Early tree life history and demography are driven by interactions with the environment such as seed predation, herbivory, light availability, and drought. For oak (Quercus) in the eastern United States, these interactions may contribute to oak regeneration failure. Numerous studies have examined the impact of individual factors (like seed predation) on the oak regeneration process, but less inf...
After some twenty years as a cultural historian with a profound interest in sport, several issues now seem especially relevant if the history of sport is to gain unqualified approval, win unequivocal admiration, and achieve unassailable recognition. The history of sport has developed from a seed into a sapling in some 25 years. While some leaves have fallen, while some branches have died or are...
Photoaffinity labeling is a reliable analytical method for biological functional analysis. Three major photophores--aryl azide, benzophenone and trifluoromethyldiazirine--are utilized in analysis. Photophore-bearing L-phenylalanine derivatives, which are used for biological functional analysis, were inoculated into a Klebsiella sp. isolated from the rhizosphere of a wild dipterocarp sapling in ...
In a recent rapid communication, Duchesne and Ouimet (2009. Can. J. For. Res. 39: 2273–2282) reported that the current expansion of American beech (Fagus grandifolia Ehrh.) in Quebec is mainly caused by soil base cation depletion due to atmospheric acid deposition. They based their conclusions on an examination of the relationships between stem densities in the sapling and tree strata compared ...
This paper proposes a new direction in Adversarial Information Retrieval through automatically ranking links. We use techniques based on Latent Semantic Analysis to define a novel algorithm to eliminate spam sites. Our model automatically creates, suppresses, and reinforces links. Using an appropriately weighted graph spam links are assigned substantially lower weights while links to normal sit...
Bud break and height-growth of Scots pine (Pinus sylvestris L.) in the northern boreal zone in Lapland, Finland, was followed through the entire growing seasons in the periods 2001-2003 and 2008-2010 in sapling stands in two different locations in northern Finland set some 250 km apart along a latitudinal transect. Field measurements continued at the southern site also in 2011-2013. Air tempera...
Forests experiencing moderate- or mixed-severity fire regimes are presumed to be widespread across the western United States, but few studies have characterized these complex disturbance regimes and their effects on contemporary forest structure. Restoration of pre-fire-suppression open-forest structure to reduce the risk of uncharacteristic stand-replacing fires is a guiding principle in fores...
