For that purpose an all-Estonian networ...

We investigated the effect of plot-based and unrestricted (plot-less) sampling on an inventory of amegadiverse taxon, spiders, in an Afrotropical forest for the purpose of species richness estimates. We also investigated the efÞciency of human-based sampling methods and the effect of allocation of sampling effort to different samplingmethods to cover asmanymicrohabitats as possible. In the 10-d...

estimating the amount of variation due to spatial dependence at different scales provides a basis for designing effective experiments. accurate knowledge of spatial structures is needed to inform silvicultural guidelines and management decisions for long term sustainability of forests. furthermore, geostatistics is a useful tool to describe and draw map the spatial variability and estimation of...

Fire, as a natural ecological disturbance factor in forest, this study located in the Marivan region, Northern Zagros forest, and western Iranian state of Kurdistan. In each burned and unburned area 30 circle sample plot (1000 m2) were collected by randomized–systematic method in the 100×200 m net (in total 60 plots). In every sample plot the kind of species, number of tree, the heig...

Aims The coastal Brazilian rainforest on white-sand (restinga) ranks among the most fragmented forest types in the tropics, owing to both the patchy distribution of sandy soils and widespread coastal development activities. Here we study the environmental and evolutionary determinants of a forest tree assemblage at a single restinga forest in Southeastern Brazil. We also explore the ability of ...

Australia has the sixth largest forest area in the world, consisting of 164 million hectares covering 21% of the continent. The Australian government has invested in research for management of forests by construction of forest database and detection of forest change. The full waveform lidar study for the extraction of plot statistics such as percentile tree counts, stem measurement, and canopy ...

The habitat use and seasonal migratory pattern of birds in Ethiopia is less explored as compared to diversity studies. To this end, this study aimed at investigating the patterns of distribution related to seasonality and the effect of habitat characteristics (elevation, slope, and average vegetation height) on habitat use of birds of Wondo Genet Forest Patch. A stratified random sampling desig...
