- Abstract
The article presents a study that discusses the implication of using demography and movement behavior to predict the range expansion of the southern sea otter. According to the article, basic demographic data along with the movement data provide a means for predicting rates of range expansion. Through the use of southern sea otter as a case study, the researchers utilized integro-difference equations together with a stage-structured projection matrix that incorporated spatial variation in dispersal and demography to make forecast of population recovery and range recolonization. It further stresses that the approach provides guidance for the acquisition of further data and a means of forecasting the consequence of specific management actions.
