What do you believe is the single most important factor driving up the cost of living in Nigeria?

Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a "genetic database" to fall back on to adapt to environmental change.

The Iberian lynx (Lynx pardinus) is no stranger to this reduction in diversity. Human activity has driven populations to dangerously low numbers, leaving them with a shrinking genetic pool. This loss threatens the lynx's ability to adapt to changing environments, putting their survival at risk.

Our team's research reveals how the Iberian lynx interbred with its cousin, the Eurasian lynx (Lynx lynx) over the past few thousand years. This mingling may have boosted the Iberian lynx's genetic diversity. This is a crucial factor for its survival, especially as the species faces such an uncertain future.

Low genetic diversity can lead to "inbreeding depression", where closely related animals breed and produce offspring that are less fit for survival. In extreme cases, this can push entire populations, or even species, to the brink of extinction.

To boost the genetic diversity of populations on the brink, conservationists sometimes turn to "genetic rescue". This involves introducing individuals from different populations in the hope that they will breed with the local animals, reducing inbreeding and enhancing genetic diversity.
