Research overview: male tenure length and pride stability

The length of time a male coalition holds a pride is a master variable in lion ecology because it governs how many of their cubs survive to independence. This overview synthesizes research linking coalition size to tenure, showing that larger coalitions hold prides longer and thereby give their cubs the years of stability needed to mature before the next takeover. It reviews how the timing of takeovers, the synchronization of female breeding, and the threat of infanticide all flow from this central rhythm of male turnover. The synthesis connects individual coalition dynamics to pride demography and population recruitment. For long-term observers it provides the framework for understanding why some prides flourish for years while others are repeatedly disrupted, and why the arrival of new males is such a pivotal event in the life of a pride.
