Growth, bimaturation, and sexual size dimorphism in wild gray-headed flying foxes (Pteropus poliocephalus)

J. A. Welbergen.

in Journal of Mammalogy

February 2010; p ublished online February 2010 .

Journal Article. Subjects: Zoology and Animal Sciences; Animal Behaviour and Behavioural Ecology; Animal Ecology; Animal Physiology; Mammalogy. 6310 words.
