Critical Ising Model and Cycle Rooted Spanning Forests: an explicit correspondence
Critical Ising Model Cycle Rooted Spanning Forests explicit correspondence
2011/2/24
Fisher established an explicit correspondence between the 2-dimensional Ising model defined on a graph G and the dimer model defined on a decorated version G of this graph [Fis66]. In this paper, we p...

Fisher established an explicit correspondence between the 2-dimensional Ising model defined on a graph G and the dimer model defined on a decorated version G of this graph [Fis66].
Spatial distribution of surface hoar crystals in sparse forests
Spatial distribution surface hoar crystals sparse forests
2010/10/20
Surface hoar size and location relate directly to avalanche initiation trigger points, and they do so in small-scale spatial distributions. Physically, surface hoar will grow where the snow surface is...
Isotope enrichment in mangrove forests separates microphytobenthos anddetritus as carbon sources for animals
Isotope enrichment mangrove ests separates microphy tobenthos anddetritus carbon sources animals
2014/4/16
Microphytobenthos (MPB) and mangrove detritus were labeled with a carbonisotope (13C) in separate experiments to quantify their contributions to the nutrition of major faunal components within a mangr...
Characterization of a large biogenic secondary organic aerosol event from eastern Canadian forests
a large biogenic secondary organic aerosol event eastern Canadian forests
2010/8/12
Measurements of aerosol composition, volatile organic compounds, and CO are used to determine biogenic secondary organic aerosol (SOA) concentrations at a rural site 70 km north of Toronto. These biog...
Fine root dynamics for forests on contrasting soils in the Colombian Amazon
Fine root dynamics forests contrasting soils the Colombian Amazon
2010/1/21
It has been hypothesized that as soil fertility increases, the amount of carbon allocated to below-ground production (fine roots) should decrease. To evaluate this hypothesis, we measured the standing...
Above- and below-ground net primary productivity across ten Amazonian forests on contrasting soils
Above- and below-ground net primary productivity ten Amazonian forests contrasting soils
2010/1/21
The net primary productivity (NPP) of tropical forests is one of the most important and least quantified components of the global carbon cycle. Most relevant studies have focused particularly on the q...
Patterns of dissolved organic carbon and nitrogen fluxes in deciduous and coniferous forests under historic high nitrogen deposition
dissolved organic carbon nitrogen fluxes deciduous and coniferous forests historic high nitrogen deposition
2010/1/21
Numerous recent studies have indicated that dissolved organic carbon (DOC) and nitrogen (DON) play an important role in C and N cycling in natural ecosystems, and have shown that N deposition alters t...
Multi-scale comparisons of tree composition in Amazonian terra firme forests
Multi-scale comparisons tree composition Amazonian terra firme forests
2010/1/21
We explored the floristic composition of terra firme forests across Amazonia using 55 plots. Firstly, we examined the floristic patterns using both genus- and species-level data and found that the spe...
Cold oceans enhance terrestrial new-particle formation in near-coastal forests
Cold oceans terrestrial new-particle formation near-coastal forests
2009/11/19
The world's forests produce atmospheric aerosol by emitting volatile organic compounds (VOC) which, after being oxidized in the atmosphere, readily condense on the omnipresent nanometer-sized nuclei a...
A new parametrization for ambient particle formation over coniferous forests and its potential implications for the future
ambient particle formation coniferous forests potential implications future
2009/11/9
Atmospheric new particle formation is a general phenomenon observed over coniferous forests. So far nucleation is either parameterised as a function of gaseous sulphuric acid concentration only, which...
Literature review of stemflow generation and chemical characteristics in Japanese forests
Stemflow generation Understory tree Chemical characteristics Acidification Forest management
2009/7/14
Stemflow has a significant influence on hydrological and ecological processes within forests. However, research on stemflow is scant as stemflow comprises a very small volume compared to throughfall. ...
Contrasting carbon dioxide fluxes between a drying shrub wetland in Northern Wisconsin,USA,and nearby forests
carbon dioxide fluxes shrub wetland Northern Wisconsin
2010/1/20
Wetland biogeochemistry is strongly influenced by water and temperature dynamics, and these interactions are currently poorly represented in ecosystem and climate models. A decline in water table of a...
Process based inventory of isoprenoid emissions from European forests: model comparisons, current knowledge and uncertainties
isoprenoid emissions European forests model comparisons
2009/6/22
Large uncertainties exist in our knowledge of regional emissions of non-methane biogenic volatile organic compounds (BVOC). We address these uncertainties through a two-pronged approach by compiling a...
WANDA, a regional dynamic nitrogen model (With Aggregated Nitrogen DynAmics) for nitrate leaching from forests
nitrogen nitrate forest model
2009/3/6
Nitrate concentrations in recently infiltrated groundwater in forested areas in the Netherlands are slowly increasing towards the EU limit of 50 mg NO3 l–1. The origin of this nitrate is thought to be...
