Iberian lynx (Lynx pardinus) — lynx Also known as the Spanish lynx or the Pardel lynx, the species bears a strong resemblance to the Eurasian lynx (*Lynx lynx*), but it may be distinguished by its smaller size; short, dark-tipped tail; and the presence of long, white, beardlike fur under its chin.

Some isolated Eurasian lynx populations are vulnerable to inbreeding and inbreeding depression primarily due to their small population size and fragmented, isolated occurrence.1

When a population is small and isolated, the available pool of mates is restricted, which increases the likelihood of mating between related individuals. This process narrows the genetic base, as offspring inherit more genes in common from their parents. Inbreeding is biologically detrimental because it can lead to reduced fertility, slower growth rates, increased susceptibility to disease, and higher mortality rates.2

In the context of the Eurasian lynx, these risks are particularly acute for certain reintroduced populations in Europe that consist of fewer than 50 individuals. Protecting these populations is an ethical imperative, as maintaining genetic diversity is essential for the long-term health and survival of the species.12
