Abstract. Elasticity analysis is a useful tool in conservation biology. The relative impacts of proportional changes in fertility, juvenile survival, and adult survival on asymptotic population growth [lambda] (where In([lambda]) = r, the intrinsic rate of increase) are determined by vital rates (survival, growth, and fertility), which also define the life history characteristics of a spe...

	On the cost of reproduction in long-lived birds: the influence of environmental variability. Ecology ; INTRODUCTION A central issue in life history theory is how animals balance their investment in young against their own chances to survive and reproduce in the future (e.g., Roff 1992, Stearns 1992). This life history trade-off is referred to as the cost of reproduction and was originally proposed
