Morphometrics and testicle size of rain forest lemur species from southeastern Madagascar
Abstract
Six species of prosimians inhabiting the montane rain forest of the Ranomafana National
Park located in southeastern Madagascar were captured, weighed, and measured during
the months of May or June of 1987, 1988, and 1989. There were no significant differences
in body weights and measurements between male and femaleEulemur rubriventer (red-bellied
lemur) orEulemur fulvus rufus (red-fronted lemur). Adult femalePropithecus diadema
edwardsi (Milne Edward's sifaka) were heavier than males but the difference was not
significant. A fewAvahi laniger laniger (woolly lemur),Hapalemur aureus (golden bamboo
lemur) andH. g. griseus (gentle bamboo lemur) also were captured and measured. Body
weights of the same individual adultP. d. edwardsi changed over the three years, suggesting
variation in food availability. Although there was no difference in body weight among
adult males of two groups ofP. d. edwardsi, one male in each group had a testicular
volume four times larger than that of other males, even though these measurements
were taken five months after the breeding season. These data suggest that only one
adult male mates in each group. Testicular size of the polygynousE. f. rufus males
was significantly larger than that of the monogamousE. rubriventer. © 1992 Academic
