Feline leukemia virus (FeLV) infection is considered one of the most serious disease threats for the endangered Iberian lynx (Lynx pardinus) Over 14 years (2008–2021), we investigated FeLV infection using point-of-care antigen test and quantitative real-time TaqMan qPCR for provirus detection in blood and tissues in lynxes from Andalusia (Southern...

The feline immunodeficiency virus is a lentivirus that infects felids worldwide. It may induce a profound immunodysfunction in domestic cats, while wild felids seem less prone to disease. During routine health check monitoring of the endangered Iberian lynx populations, 465 samples from 311 individuals were tested between 2004 and 2017. All of them...

The conservation of endangered species requires accurate data, and knowledge of cause-specific mortality rates is one of the most important issues. In recent years conservation programs for the critically endangered Iberian lynx Lynx pardinus have been developed on the basis of mortality data derived 30 years ago from the small Doñana population. T...

The critically endangered Iberian lynx (Lynx pardinus) is considered the most endangered cat in the world (IUCN 2002). During the Twentieth Century, its populations suffered a dramatic decrease, and by 2002 less than 100 individuals survived in two isolated populations in Andalusia (Southern Spain): Sierras de Andújar-Cardeña and Doñana National Pa...

Over the last 2 years surveys of the population of the Iberian lynx Lynx pardinus in Doñana National Park and its surroundings in Spain have produced estimates of a total population of 5–6 in fragmented patches. The population was estimated to be 26 adults in 22–23. Use of camera trapping and other field methods during 24–28 allowed us to determine...

A principios del siglo XXI la población de lince ibérico se había quedado reducida a menos de 160 individuos localizados únicamente en 2 poblaciones: Andújar-Cardeña y Doñana. Los principales factores limitantes de la especie eran la escasez de alimento y la elevada mortalidad no natural. En vista de esto, dentro del marco de los programas de conse...

Based on both radio-tracking and photo-trapping data, we present in this paper the first evidence of a non-parental male infanticide in the Iberian lynx. This paper is focused on the behaviour of 3 Iberian lynxes [one resident male (RM); one resident female (RF), and one incoming male (IM)] of the Doñana population, recorded in the spring of 2007....

The feline leukemia virus (FeLV) is a retrovirus that affects domestic cats all over the world. Its pathogenic effects generally include anemia, immunosuppression or tumors. Dissemination over populations is linked to cat sociality, because the virus is transmitted by direct contact. Although the domestic cat is its common host, FeLV infection has...

The Feline Leukemia Virus (FeLV) is a retrovirus that affects domestic cats all over the world, occasionally affecting other felid species. Its pathogenic effects generally include anemia, immunosuppression and tumors. In the Iberian lynx (Lynx pardinus), sporadic contact has been detected since the virus began to be monitored in the population, al...
