Abstract:
... Cerrado is a biome that occupies about 25% of the Brazilian territory and is characterized by a gradient of grassland to savanna and forest formations and by high species richness. It has been severely affected by degradation and deforestation and has been heavily fragmented over the past 4–5 decades. Despite the recognized overall ecological importance of the Cerrado, there are only few studies f ...

Abstract:
... Nitrogen (N) is typically the growth-limiting factor in boreal forest ecosystems. Therefore, knowledge on forest N stocks and fluxes is crucial in order to predict and evaluate the effects of different anthropogenic factors (e.g. climate change, air pollutant deposition, forest management practices) on the condition, development and sustainability of boreal forests. In this study, we evaluated the ...

We quantified the effect of water and nutrient availability on aboveground biomass and nitrogen accumulation and partitioning in four species from the southeastern United States, loblolly pine (Pinus taeda), slash pine (Pinus elliottii), sweetgum (Liquidambar styraciflua), and sycamore (Platanus occidentalis). The 6-year-old stands received five levels of resource input (control, irrigation with 3 ...

Assessment of aboveground biomass stocks in the coniferous forests of the inland northwest USA is important for timber, bioenergy, and carbon inventories, as well as for wildfire risk determination. In this study, individual tree biomass equation systems are developed for 7 regionally important conifer species using data from 470 felled trees sampled across 84 stands and spanning a range of diamet ...

To evaluate the effects of pruning on aboveground biomass partitioning of trees and investigate the response of aboveground leaf mass fractions of trees to pruning, a pruning experiment with four pruning intensities (0, 20, 50, and 70%), two pruning seasons (spring and autumn), and four subtropical Chinese tree species was carried out. Pruning treatments were conducted in two successive years. In ...

Abstract:
... Abundance and diversity of wood-inhabiting fungi were studied in managed (sanitation cutting, commercial thinning and timber harvesting) and unmanaged stands in one 85-year-old Scots pine forest in western Poland. Fungi were detected on coarse woody debris collected in each stand in June 2014: logs, fallen branches, standing dead trees and stumps, in the 1st, 2nd and 3rd classes of decay. Fungi we ...

Abstract:
... Harvesting of stumps and logging residues for bioenergy can be expected to increase in the future. An increased biomass export from the forest will increase the biological acidification, measured as net cation (cations–anions) export. The aim of this study is to estimate the acidifying effect that various levels of harvesting of tree stumps and logging residues will have in Sweden, and compare thi ...

Abstract:
... Snags (standing dead trees) are an essential structural component of forests. Because wildlife use of snags depends on size and decay stage, snag density estimation without any information about snag quality attributes is of little value for wildlife management decision makers. Little work has been done to develop models that allow multivariate estimation of snag density by snag quality class. Usi ...

A split plot trial involving Ailanthus triphysa (ailanthus) at four spacings ( m, m, m and m) and four fertiliser regimes (0:0:0, 50:25:25, 100:50:50 and 150:75:75 kg ha−1 per year N, P2O5, K2O) was initiated in June 1991.

Abstract:
... The possibility of estimating young trees biomass is rather limited because forest yield tables are constructed starting from higher thresholds of proxy, such as diameter or height, and lack of availability of allometric equations. The aim of this study is to provide species-specific and general biomass equations for young plants often used for plantations on marginal lands in southern and eastern ...

Abstract:
... Moist tropical forests in Africa and elsewhere store large amounts of carbon and need accurate allometric regressions for their estimation. In Africa the absence of species-specific or mixed-species allometric equations has lead to broad use of pan moist tropical equations to estimate tree biomass. This lack of information has raised many discussions on the accuracy of these data, since equations ...

Abstract:
... Mangrove forests can fix and store high quantities of carbon both in their soil and in their biomass, the latter peaking in the equatorial regions and decreasing with latitude. In Vietnam, more than 80% of the mangroves develop either in the Mekong Delta or in the Can Gio Estuary, which are characterized by tropical monsoon climates. Most of these mangroves were planted and are dominated by Rhizop ...

High densities of white-tailed deer restrict the regeneration of tree species, reduce understory cover and diversity, enhance invasions of exotic species, and facilitate the spread of human and deer diseases. Deer managers often base management decisions on estimated deer densities and carrying capacities, generating controversy. It may be simpler, cheaper, and more appropriate to manage deer popu ...

It grows in spontaneous woodlands and forests which are fully integrated within agro-ecosystems. Local populations have for centuries shaped ash stands by sequentially trimming and pollarding individual tr ...

Abstract:
... Since individual tree leaf area is an important measure for productivity as well as for site occupancy, it is of high interest in many studies about forest growth. The exact determination of leaf area is nearly impossible. Thus, a common way to get information about leaf area is to use substitutes. These substitutes are often variables which are collected in a destructive way which is not feasible ...
