Abstract

Problems raised by relationships between food resources and reproduction in mammals and birds are various and imply many theoretical and empirical aspects of biological fields such as physiology, ecology, ethology, population biology and genetics, The study of these relationships reveals ecological or evolutionary consequences of spatial and temporal variation in abundance and quality of trophic resources on reproduction. This paper first reviews and clarifies the main concepts of life history theory and sociobiology/behavioural ecology, generally used in that literature, followed by several recommandations upon their use, Afterwards, several currently developed aspects of birds and mammalsreproduction in function of food resources availability are reviewed. Reproductive capacities and fecundity, adjustment in the number of young before or after birth or hatching, sex-ratio adjustment in the progeny and sex-biased investment,parental care, parental expenditure, parental investment and parent-offspring conflict in function of availability in food resources are analysed in details. The consequences of lowering trophic resources on some aspects of the offspring's ontogeny are also developed.
