Population Size & Reproduction

Environmental factors that may influence the reproductive process (e.g., nutrition, weather, crowding, predation, disease) often have more severe impacts on reproductive success when wildlife populations are HIGH rather than low. Why? In large populations there is more competition for both quantity and quality of food and cover, which leads us into a discussion of density-dependent reproduction….

Mating Systems

Today we’ll discuss the 3 types of Mating Systems: Monogamy, Polygamy, and Promiscuity! But first we shall go over sex ratios before getting into the main topic. Sex Ratios express the relative abundance of each sex in wildlife populations. Sex ratios are expressed as “the number of males: the number of females“ 50 : 50 even sex…
