A Demo-Genetic Analysis of a Small Reintroduced Carnivore Population: The Otter (Lutra lutra) in The Netherlands

Figure 4

Sensitivity of 𝜆 to varying adult demographic rates (range [ 0 , 1 ]), when juvenile survival ( 𝑠 𝑗 ) is set to (a) 0.12 and (b) 0.964 (observed juvenile mortality, see Table 2). Bold line ( 𝜆 = 1 ) represents the separation between set of parameters resulting in decline of the population and those resulting in growth. Dotted lines indicate the current values for 𝑠 𝑎 (adult female survival) and 𝑓 𝑎 (net reproduction of female native-born cubs per adult female per year).
