Introgressive hybridization with introduced species is threatening the genetic integrity of many native fish populations worldwide. To date, several studies have indicated a direct relationship between rates of hybridization (H) within a sub-population of native fish and the stream distance (D) separating that sub-population from the closest source of introduced non-native genes. However, the relationship...
Testing ecological models involves using independent data on model performance, which can be difficult or practically impossible to obtain. Individual based models of forest dynamics, or gap models, simulate the change of forests by computing the annual growth, birth and death of each tree at a location in a forest. The models are relatively simple and simulate results that can be translated to multiple...
