Endan­gered Iber­ian Lynx Fac­ing New Threat

pub­lished 24 Sep­tem­ber 2010 | mod­i­fied 11 March 2010

Con­ser­va­tion­ist groups are report­ing that the Iber­ian Lynx, world’s top endan­gered feline species, is fac­ing a new chal­lenge, Chronic Kid­ney Dis­ease (CDK).

In a state­ment released on March 9, 2010, the Lynx Con­ser­va­tion Pro­gram states that three of the 72 Iber­ian Lynx (Lynx par­di­nus) raised in breed­ing cen­ters in Spain have suc­cumbed to the ill­ness, and 25 of the ani­mals housed at the country’s two breed­ing cen­ters have shown symp­toms of CDK. The vet­eri­nar­i­ans at the cen­ters say that they are work­ing and con­sult­ing with experts to try to find the pos­si­ble ori­gin of the CKD, as well as try­ing to pre­vent the emer­gence of new cases. How­ever, their main focus right now is on main­tain­ing and pro­vid­ing pal­lia­tive care to the high per­cent­age of the pop­u­la­tion affected by this dis­ease. A report from a study by the Depart­ment of Ani­mal Med­i­cine and Surgery at the Uni­ver­sity of Madrid, said: “Lit­tle is known about the dis­eases that affect these ani­mals in the wild or in cap­tiv­ity. The serum bio­chem­istry and uri­nal­y­ses revealed signs of mild chronic kid­ney dis­ease in 16 of the 23 ani­mals eval­u­ated, a pro­gres­sive dis­ease of immune ori­gin. We pos­tu­late a pos­si­ble genetic pre­dis­po­si­tion towards the dis­ease, enhanced by inbreed­ing and a pos­si­ble con­nec­tion to an immune-​mediated sys­temic disease.”

The Iber­ian lynx is one of the world’s most endan­gered cat species (IUCN sta­tus: crit­i­cally endan­gered), due to a cat­a­strophic com­bi­na­tion of habi­tat loss, lack of prey and inci­den­tal and inten­tional killings. There are believed to be less than 200 Iber­ian Lynx left world­wide. Accord­ing to infor­ma­tion attrib­uted to the con­ser­va­tion group SOSL­ynx and pub­lished in an April 2002 guardian​.co​.uk arti­cle, if the Iber­ian Lynx becomes extinct, it would be the first mem­ber of its ani­mal fam­ily to die out since pre­his­toric times, the saber-​toothed cat.
