Macroecological patterns of rodent population dynamics shaped by bioclimatic gradients
Long-term studies of cyclic rodent populations have contributed fundamentally to the development of population ecology. Previous research has shown macroecological patterns of population dynamics in relation to latitude, but without disentangling the role of underlying ecological and climate drivers...

Long-term studies of cyclic rodent populations have contributed fundamentally to the development of population ecology.
