Surviving the Squeeze: Genomic Analysis of a Successful Invasion by European Common Wall Lizards (Podarcis muralis) in North America (Ohio, USA). [PDF]
ABSTRACT Invasive species that undergo a founder event may experience a decline in genetic diversity yet still establish successful populations. A possible example is a population of the common wall lizard (Podarcis muralis) in Cincinnati, Ohio, USA, which was founded following an introduction in the 1950s of a small number of individuals from Europe ...

Fast Outlier Detection Using a Grid-Based Algorithm. [PDF]
As one of data mining techniques, outlier detection aims to discover outlying observations that deviate substantially from the reminder of the data. Recently, the Local Outlier Factor (LOF) algorithm has been successfully applied to outlier detection ...
