A.W. Green, L.L. Bailey, J.D. Nichols
2011, Journal of Applied Ecology (48) 1007-1016
1. Dynamic occupancy models are often used to investigate questions regarding the processes that influence patch occupancy and are prominent in the fields of population and community ecology and conservation biology. Recently, multistate occupancy models have been developed to investigate dynamic systems involving more than one occupied state, including reproductive states,...
