These questions help us understand the perception of security from people at three different geographic levels: locality, county and state, where the county is formed by a set of localities and a state is formed by a group of counties.
The input for model building consists of (1) a set of localities of known occurrence of the target species, and (2) environmental data from digital maps (e.g., annual temperature, annual precipitation, altitude) for the target region.
Model performance was calculated by measuring the levels of agreement (using κ) between a set of testing localities (distribution records not used for model building) and each of the model predictions.
Statistical methods of ecological niche modeling, such as maximum entropy (implemented in the program MaxEnt [6] used here) take a set of presence localities and a set of climatic variables and fit a statistical distribution to those points which best describes the fundamental ecological niche with respect to the available climate data.
MaxEnt's regularization parameter settings based on a mix of plants and animals might or might not be appropriate for pythons, or for a particular set of localities such as clustered point locations.
We analysed a partial sequence of the Cytochrome c Oxidase Subunit I mitochondrial gene from an extensive set of localities (including Eurasia, Africa, and Australia), and examined their phylogeographic patterns and the phylogenetic relationships of diploid A. parthenogenetica and its closest sexual relatives.
As the work at Aramis was progressing, Middle Awash geologist Giday WoldeGabriel and then graduate student Yohannes Haile-Selassie were exploring an older set of localities that dated to between 5 million and 6 million years ago, They found hominid remains in 1997.
We recorded a significant, although slight, pattern of isolation by distance for the set of localities sampled; however, we noticed that this pattern seems mainly driven by distances from the most distant localities.
GARP is based on a genetic algorithm and is used to find a set of rules describing nonrandom associations between localities where disease transmission has been reported and environmental conditions in those localities (32, 33 ).
On the one hand, the area includes the Monte Hermoso cliffs studied by Charles Darwin in 1832, which compose the set of localities related to the development of the theory of evolution.
Geographic areas were calculated by using the Berkeley Mapper mapping interface (http://berkeleymapper.berkeley.edu) to zoom in on the set of localities at appropriate scales, trace the minimum convex polygon that would enclose all the localities of interest within a particular province, and calculate the area enclosed by the polygon.
