ABSTRACT The pervasive influence of island biogeography theory on forest fragmentation research has often led to a misleading conceptualization landscapes as areas forest/habitat and ‘non‐forest/non‐habitat’ an overriding focus processes within remnants at the expense in human‐modified matrix. matrix, however, may be neither uniformly unsuitable habitat nor serve fully–absorbing barrier dispersal taxa. In this paper, we present conceptual model that addresses how loss affect biodiversity...
Abstract. Numerous ecological studies use Principal Components Analysis (PCA) for exploratory analysis and data reduction. Determination of the number components to retain is most crucial problem confronting researcher when using PCA. An incorrect choice may lead underextraction components, but commonly results in overextraction. Of several methods proposed determine significance principal Parallel (PA) has proven consistently accurate determining threshold significant variable loadings,...
Abstract Aims Classification of vegetation is an essential tool to describe, understand, predict and manage biodiversity. Given the multiplicity approaches classify vegetation, it important develop international consensus around a set general guidelines purpose‐specific standard protocols. Before these goals can be achieved, however, necessary identify understand different choices that are made during process classifying vegetation. This paper presents framework facilitate comparisons...
Fire is an integral component of ecosystems globally and a tool that humans have harnessed for millennia. Altered fire regimes are fundamental cause consequence global change, impacting people the biophysical systems on which they depend. As part newly emerging Anthropocene, marked by human-caused climate change radical changes to ecosystems, danger increasing, fires having increasingly devastating impacts human health, infrastructure, ecosystem services. Increasing vexing problem requires...
Abstract Niche and neutral theories emphasize different processes contributing to the maintenance of species diversity. In this study, we calculated local contribution beta diversity (LCBD) every cell, using variation partitioning in combination with spatial distance environmental variables 25-ha Badagongshan plot (BDGS), determine environmentally-related versus pure variation. We used topography soil characteristics as variables, distance-based Moran’s eigenvectors maps (dbMEM) describe...
Inferring the processes underlying spatial distribution patterns of tree species is fundamental for understanding coexistence. Here, we examined woody plants by using univariate pair correlation function to quantify in a fullly mapped 25 ha subtropical plot China. We analyzed relationships between attributes and 137 with at least one individual per hectare. The results showed that aggregated distributions were dominant pattern Badagongshan forests, percentage significantly decreased...
Subtropical forests are important carbon sinks and have a huge potential for mitigating climate change. However, few studies developed biomass models to give robust estimates of subtropical forest aboveground belowground biomass. Although wood density (WD) can greatly reduce the uncertainty in (AGB) tropical forest, it has never been applied other ecosystems. In addition, crowns hold large component tree vary among types, so crown dimensions as new variables recommended AGB models. To test...
Two upland Quercus sites were burned during the dormant season to assess small-scale spatial effects of fire on forest community structure. Fuel data obtained prior burning, temperatures at three heights taken fire, and microtopographic vegetation collected following burn. Spatial analysis pattern employed examine temperature patterns in relation microtopography fuels, vegetation. Fire surface, 33 cm above 75 surface light moderate ranging from 52 260°C. These fires probably have no adverse...
Endemics–Area Relationships (EARs) are fundamental in theoretical and applied biogeography for understanding distribution patterns promoting biodiversity conservation. However, calculating EARs vascular plant species from existing data is problematic because of biased knowledge endemic distributions differences between taxonomies. We aimed to overcome these challenges by developing a new standardized global dataset based on expert produce set EARs. developed nested circle design, with grain...
Abstract 133 stands from the uplands of Land Between The Lakes (LBL) were sampled. Stand data ordinated to identify clinal patterns in overstory vegetation. A coeno‐cline, accounting for 52% species variance, was developed first ordination axis. Classification identified nine dominance types: Pinus echinata‐Quercus spp., Q. prinus, prinus‐Q. alba, stellata‐Q. velutina‐Q. alba‐Q. rubra, Acer saccharum‐Q. alba‐Fagus grandifolia sadF. grandifolia‐A. saccharum. Compositionally‐stable (climax)...
Temporal partitioning in foraging patterns of syntopic Virginia opossums (Didelphis virginiana) and raccoons (Procyon lotor) was investigated at 3 sites western Tennessee through the use timers attached to live traps on trapping grids time-stamped remote photography using infrared-triggered cameras bait stations. Data were analyzed Watson's U2-test, chi-square analyses, probability tests. Results revealed no intraspecific differences time for either species a lack interspecific...
Topography has long been recognized as an important factor in shaping species distributions. Many studies revealed that may show species–habitat associations. However, few investigate how assemblages are associated with local habitats, and it still remains unclear the community–habitat associations vary abundance class life stage. In this study, we analyzed a subtropical montane forest. The fully mapped 25-ha (500×500 m) forest plot is located Badagongshan Nature Reserve Hunan Province,...
