The spatial patterns of genetic structure among juveniles of long-lived species can reveal the extent of interannual and geographic variation in realized larval dispersal as well as the processes that determine ecologically relevant patterns of population connectivity. However, few studies examine this temporal and spatial variation over large portions of a species’ geographic range or between ...

One of the potentially most relevant pieces of metadata for filtering studies in environmental science is the geographic region in which the study took place (the “study region”). In this paper, we apply support vector machines to the automatic classification of study region in a dataset of titles and abstracts from environmental science literature, using features including frequency distributi...

Nepal, with an area of 147,181 square kilometers (km), is a land of enormous geographical diversity. The country has three main geographical/ecological regions: the terai region, the hill region and the mountain region, which cover 23.1 percent, 41.7 percent, and 35.2 percent of the total area, respectively. Each ecological region is a narrow strip of land stretching from east to west. These th...

Topological relativity is a concept of interest in geographic information theory. One way of assessing the importance of topology in spatial reasoning is to analyze commonplace terms from natural language relative to conceptual neighborhood graphs, the alignment structures of choice for topological relations. Sixteen English-language spatial prepositions for regionregion relations were analyzed...
