Sexual Signalling in Propithecus verreauxi: Male “Chest Badge” and Female Mate Choice
Communication, an essential prerequisite for sociality, involves the transmission of signals. A signal can be defined as any action or trait produced by one animal, the sender, that produces a change in the behaviour of another animal, the receiver. Secondary sexual signals are often used for mate choice because they may inform on a potential partner's quality. Verreaux's sifaka (Propithecus ve...
متن کاملIntrasexual selection in Verreaux's sifaka (Propithecus verreauxi verreauxi).
Studies of sexual selection show that both female choice and male-male competition can influence the evolution and expression of male phenotypes. In this regard, it is important to determine the functional basis through which male traits influence variation in male reproductive success. In this study, we estimate the strength and type of sexual selection acting on adult males in a population of...
متن کاملPolyboroides radiatus predation attempts on Propithecus verreauxi.
Observations of raptor predation on lemurs are rare [reviewed in Goodman et al., 1993], but indirect evidence derived from raptor prey remains [Karpanty and Goodman, 1999; Thorstrom and La Marca, 2000], raptor pellets [Goodman et al., 1993], and vocal/behavioral responses to potential avian and terrestrial predators [Sauther, 1989; Karpanty and Grella, 2001; Schülke, 2001; Fichtel and Kappeler,...
متن کاملLife in the slow lane? Demography and life histories of male and female sifaka (Propithecus verreauxi verreauxi)
A 16-year study of wild, unprovisioned sifaka Propithecus verreauxi verreauxi at Beza Mahafaly in southwest Madagascar provides estimates of age-speci®c fertility, mortality, and dispersal in a population of 426 marked animals, and longitudinal records of individual life histories. Sifaka females give birth for the ®rst time later and live longer, for their size, than mammals in other orders; t...
متن کاملCharacterization and screening of microsatellite loci in a wild lemur population (Propithecus verreauxi verreauxi).
Sixteen dinucleotide microsatellite loci were isolated from the genome of Propithecus verreauxi verreauxi. All loci were polymorphic when genotyped on a minimum of 16 animals. The number of alleles across these loci ranges from two to 11. Additionally, seven of these loci were genotyped across a minimum of 200 animals in order to estimate heterozygosity and their potential for parentage assignm...
