Estimation of demographic history from nucleotide sequences represents an important component of many studies in molecular ecology. For example, knowledge of a population's history can allow us to test hypotheses about the impact of climatic and anthropogenic factors. In the past, demographic analysis was typically limited to relatively simple population models, such as exponential or logistic ...

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 ...

Many statistical analyses can be undertaken to examine the relationship between two continuous variables within a group of subjects. Two of the main purposes of such analyses are: To assess whether the two variables are associated. There is no distinction between the two variables and no causation is implied, simply association. To enable the value of one variable to be predicted from any known...

Given a first-order sentence ? and domain size n, how can one sample model of on the {1, . , n} efficiently as n scales? We consider two variants this problem: uniform sampling regime, in which goal is to uniformly at random, symmetric weighted models are according number groundings each predicate appearing them. Solutions problem have applications scalable generation combinatorial structures, ...

We present the near-Maximal Algorithm for Poisson-disk Sampling (nMAPS) to generate point distributions variable resolution Delaunay triangular and tetrahedral meshes in two three-dimensions, respectively. nMAPS consists of principal stages. In first stage, an initial distribution is produced using a cell-based rejection algorithm. second holes sample are detected efficient background grid fill...

The objective of the present study was to develop a model to predict lichen species richness for six test sites in the Swiss Pre-Alps following a gradient of land use intensity combining airborne remote sensing data and regression models. This study ties in with the European Union Project BioAssess which aimed at quantifying patterns in biodiversity and developing “Biodiversity Assessment Tools...
