The evolution of social philopatry and dispersal in female mammals
- BiologyMolecular ecology
In most social mammals, some females disperse from their natal group while others remain and breed there throughout their lives but, in a few, females typically disperse after adolescence and few…
Group structure, kinship, inbreeding risk and habitual female dispersal in plural‐breeding mammals
- BiologyJournal of evolutionary biology
In most plural‐breeding mammals, female group members are matrilineal relatives but, in a small number of species, all adult females are immigrants who are seldom closely related to each other. Some…
Sex-biased survival and philopatry in birds: Do they interact?
- Environmental ScienceBiology Bulletin
The comparison between sex-related mortality and natal and breeding dispersal at the species-level shows that dispersing birds suffer higher mortality, while philopatric birds have higher survival.
Male-biased dispersal, female philopatry, and routes to fitness in a social corvid
Social behaviour appears to affect a reversal in sex-specific costs and benefits of dispersal, so that females benefit from philopatry and matrilineal inheritance, while males benefit from expanded dispersal options in part through kin facilitation, but without effective mate defence or clear cut sex- specific resource defence.
Movement patterns of the common lizard ( Lacerta vivipara ) in relation to sex and age
- Biology, Environmental Science
Differences in age and sex are likely to be two major components of the dispersal pattern in the common lizard, which is similar to most vertebrates and should involve mainly young individuals.
Higher reproductive skew among birds than mammals in cooperatively breeding species
- Biology, Environmental ScienceBiology Letters
It is suggested that viviparity reduces the ability of dominant females to control subordinate reproduction and that, as a result, dominant female birds are more able than their mammal counterparts to prevent subordinates from breeding.
More on Juvenile Dispersal in Mammals
This work contends that the "cost" of dispersal may be over-emphasized and confused with the cost of being male, and argues against resource and/or reproductive competition as a motivation for juvenile dispersal.
Sex-Biased Dispersal and Social Systems of Neotropical Emballonurids
This book chapter contrasts sex-biased dispersal and the social systems of three well-studied Neotropical bat species of the family Emballonuridae and discusses the evolutionary pressures driving the observed dispersal patterns and how sexual selection in Neotropicals Em ballonurids with male philopatry might shape bat sociality.
Implications of Monogamy for Infant Social Development in Mammals
Monogamy is a relatively rare mating system among the mammals, probably because of the ability of the mammalian female to rear offspring in the absence of any parental investment by a male. Females…

Monogamy in Mammals
- BiologyThe Quarterly Review of Biology
This review considers the behavioral, ecological, and reproductive characteristics of mammals exhibiting monogamy, i.e., mating exclusivity. From a discussion of the life histories of selected…
Inbreeding and dispersal in the great tit
- Biology, Environmental ScienceNature
The first detailed evidence of inbreeding depression in a natural population is presented and support for the hypothesis that one function of dispersal between birth and breeding sites is to reduce an individual's chance of in breeding is supported.
The Evolution of Mating Systems in Birds and Mammals
- Biology, Psychology
Mating system theory must mesh with theoretical advances concerning the evolution of territoriality, parental behavior, and animal sociality and by including the appropriate theoretical work from these other areas, an integrated theory of vertebrate mating systems can be developed.
EVOLUTION OF POLYGAMY IN THE LONG‐BILLED MARSH WREN
It is pointed out that if sexual selection results in sexual dimorphism expressed during the period of parental care, there may be a change in average expenditure per sex with a consequent change in sex ratio, and mate preference, which in my opinion should have a profound influence on the mating system, may also have an effect on the sex ratio.
Mammals in Which Females are Larger Than Males
- Biology, Environmental ScienceThe Quarterly Review of Biology
Present knowledge about the species of mammals in which females are larger than males is quite rudimentary and much more information is needed before the authors will be able to speak of the selective pressures accounting for the phenomenon with any reasonable degree of certainty.
Social organization and reproduction in equids.
- BiologyJournal of reproduction and fertility. Supplement
There are two distinct types of social organization and, accordingly, two types of mating systems in equids. In the horse, Plains zebra and Mountain zebra, the adults live in non-territorial and…
THE ADAPTIVE SIGNIFICANCE OF VARIATION IN BREEDING AREA FIDELITY OF THE BLACKBIRD (TURD US MERULA L.)
- Environmental Science
This paper examines the breeding dispersal of the blackbird using data collected in the British Isles by members of the British Trust for Ornithology (B.T.O.) over the last twenty years.
Male emigration and female transfer in wild mountain gorilla
- Environmental ScienceNature
This paper provides the first extensive evidence that both male and female gorillas leave their natal group, although some sons may remain; that males that leave initially travel alone; and that only females transfer.
Innate and Environmental Dispersal of Individual Vertebrates
- Biology, Environmental Science
Growing evidence suggests that the observed dispersal patterns may be governed by the laws of heredity as well as being influenced by population pressure.
