Krista J. Patriquin, Marty L. Leonard, Hugh G. Broders, W. Mark Ford, Eric R. Britzke, Alexander Silvis
2016, Animal Behaviour (122) 47-57
Fission–fusion dynamics appear common among temperate bats where females form roost groups that change in size and composition, as females switch roosts almost daily. One hypothesis for frequent roost switching is that females move to find suitable thermal conditions as ambient conditions change. Tests of this hypothesis have, however, been...
