ISSN:

Subject:
coarse woody debris; forest litter; new methods
Abstract:
... A new sampling method for down coarse woody debris is proposed based on limiting the perpendicular distance from individual pieces to a randomly chosen sample point. Two approaches are presented that allow different protocols to be used to determine field measurements; estimators for each protocol are also developed. Both protocols are compared via simulation against existing sampling methods that ...

Abstract:
... We used the Landscape Function Analysis (LFA) (sensu Tongway and Hindley, 2004) to assess the development of ecosystem function in revegetation, particularly in relation to the basic ecological functions of soil stability, water infiltration and nutrient cycling. We compared these three LFA indices between two types of revegetation plantings, remnants, and cleared agricultural land (paddocks), in ...

Abstract:
... The Juma Sustainable Development Reserve, located in Brazil’s state of Amazonas, was the first protected area in Brazil to be benefited by a Reducing Emissions from a Deforestation and Degradation (REDD) project. However, the carbon benefits of REDD projects may be compromised by leakage, or displacement of deforestation to areas outside of the reserve. Through environmental modeling techniques it ...

Abstract:
... A pervasive pattern of forest composition change is occurring throughout the Central Hardwood Forest of the eastern US. Acer rubrum has invaded the understory of Quercus stands across a variety of site types. The proliferation of A. rubrum, and that of other shade-tolerant mesophytes, inhibits the regeneration of Quercus. Without alterations in disturbance or climate regimes, composition in invade ...

Abstract:
... In temperate conifer forests of the Western USA, there is active debate whether fuels reduction treatments and bioenergy production result in decreased carbon emissions and increased carbon sequestration compared to a no-action alternative. To address this debate over net carbon stocks, we performed a carbon life-cycle analysis on data from a fuels reduction treatment in a temperate, dry conifer f ...

The survival of 86 clutches laid by hazel grouse Bonasa bonasia hens was studied using radio telemetry to evaluate the importance of key vegetation variables for nest survival between March 2003 and June 2009 in a 3000ha study area of temperate forest in South Korea. The nest sites in the forest stands differed from that in the study area with dense understory cover and low visibility. Daily nest ...

Abstract:
... Disturbances such as fire profoundly affect plants, but their effects are strongly dependant on species’ biological and life-history traits. Thus, in Mediterranean-type ecosystems (MTEs), where the frequencies and intensities of fires are increasing in association with ongoing land use and climate changes, the composition and diversity of plant communities may change at both species and trait le ...

Prunus emarginata (bitter cherry) is a shade-intolerant tree that can develop in abundance (>20,000 stems ha⁻¹) from a seedbank after disturbance in forests along the northwest coast of North America. It can inhibit growth of commercially valuable conifers, but also provide hab ...
