Current Iberian lynx population is not genetic viable in the long term

A study of the Doñana Biological Station – CSIC determined that 1100 reproductive females, triple the 2022 census, are needed to guarantee the genetic viability of this species

On the path to extinction: inbreeding and admixture in a declining gray wolf population

Allee effects reduce the viability of small populations in many different ways, which act synergistically to lead populations towards extinction vortexes. The Sierra Morena wolf population, isolated in the south of the Iberian Peninsula and composed of just one or few packs for decades, represents a good example of how diverse threats act additively in very small populations. The genome of one of the last wolves identified (and road?killed) in Sierra Morena and that of another wolf in the...

A father effect explains sex-ratio bias

Sex ratio allocation has important fitness consequences, and theory predicts that parents should adjust offspring sex ratio in cases where the fitness returns of producing male and female offspring vary. The ability of fathers to bias offspring sex ratios has traditionally been dismissed. In this study sex ratio is explained by an exclusive effect of the father, and suggest a likely mechanism by which male-driven sex-ratio bias is attained.

Extreme genomic erosion in the highly endangered Iberian lynx

Genomic studies of endangered species provide insights into their evolution and demographic history, reveal patterns of genomic erosion that might limit their viability, and offer tools for their effective conservation. The Iberian lynx (Lynx pardinus) is the most endangered felid and a unique example of a species on the brink of extinction. The first annotated draft of the Iberian lynx genome has been generated and genome-based analyses of lynx demography, evolution, and population genetics...
