Reproductive success for social Hymenoptera
Theoretical Population Biology, 1978Abstract An organism's “reproductive success” is a quantity designed to measure the extent to which genes descended from that organism will be represented in distant future generations. A mathematical justification is given for the formulation of reproductive success used in a recent study of the evolution of sex ratio in eusocial Hymenopteran ...

Autoantibodies, alloantibodies and reproductive success
Current Opinion in Immunology, 1990It is only since the recognition of rhesus haemolytic disease that the importance of the maternal immune response to fetal antigens has been widely appreciated. The discovety that rhesus isoimmunization can be prevented by an antibody directed against the rhesus D antigen on fetal red cells was an extremely important step forward, as it showed that the

Natural killer cells and reproductive success
American Journal of Reproductive Immunology, 2020AbstractNatural killer (NK) cell assessment has been attempted since the 1990s and, apart from antibody testing, is probably the commonest immune test available to clinicians. It is clear that simple enumeration of uterine NK cells by immunohistochemistry is inadequate, although better methodology such as flow cytometry may prove to be more beneficial ...

Failures of reproduction: problematising ‘success’ in assisted reproductive technology
Nursing Inquiry, 2007This paper scrutinises the many ways in which ‘success’ is portrayed in representing assisted reproductive technology (ART) services and illuminates how these definitions differ from those held by participant couples. A qualitative approach informed by feminist perspectives guided this study and aimed to problematise the concept of ‘success’ by ...

Voice, Sexual Selection, and Reproductive Success
2020Beyond the linguistic content it conveys, voice is one of the fundamental aspects of human communication. It conveys an array of bio-psycho-social information about a speaker and enables the expression of a wide range of emotional and affective states so as to elicit a whole range of auditory impressions.

1991
The effect of habitat supplies on the survivorship and reproductive success of plants has been fully understood (Harper and Ogden 1970, Harper 1977, Silvertown 1983). It has also been found many times that the proportions of species with different reproduction strategies vary with the succession phases (Horn 1974, Newell and Tramer 1978, Noble and ...

Reproductive success of farmed blue foxes
Journal of Animal Breeding and Genetics, 1997SummaryThe aim of this study was to provide basic data for the different components of reproductive performance of blue foxes under farm conditions. The foxes were mated naturally and the perinatal mortality of cubs was carefully recorded. This data allowed the evaluation of the effect of females' age and differences between years, and the maternal and

Reproductive success and mortality
1995Abstract Annual reproductive success (ARS) of an individual or pair of pigeons is the total of squabs successfully reared to fledging in the course of an annual reproductive bout. We know that ARS varies ontogenetically within individuals, annually within a colony, and geographically among colonies.

Behaviour and reproductive success
2015Semi-free ranging mandrill groups in Gabon Between the years 1990 and 1992, at the Centre International de Recherches Medicales de Franceville (CIRMF) in Gabon, I conducted a longitudinal study of the behaviour of the semi-free ranging mandrill group (Group 1), the seasonal patterns of reproduction of which were discussed in the last chapter.
