Medical records of 120 Iberian lynx (Lynx pardinus) from the captive breeding population (CBP), 96 of which were older than 1 wk old, were studied from January 2004 to June 2010. From a total of 413 clinical signs recorded, it was possible to obtain a diagnosis in 258 (62.5%). Inappetence, skin wound, and vomiting had the highest incidence. Adult (...

The relation among inbreeding, heterozygosity, and fitness has been studied primarily among outbred populations, and little is known about these phenomena in endangered populations. Most researchers conclude that the relation between coefficient of inbreeding estimated from pedigrees and fitness traits (inbreeding-fitness correlations) better refle...

With only about 350 individuals, the Iberian lynx Lynx pardinus continues to be the world’s most endangered felid. Ongoing conservation measures include both in-situ and ex-situ conservation programmes. As part of the first Iberian lynx reintroduction programme, two captive-born individuals were released in the wild in the 2010-2011 season for the...

The Iberian lynx is the most endangered felid species. During winter/spring 2006/7, a feline leukemia virus (FeLV) outbreak of unexpected virulence killed about 2/3 of the infected Iberian lynxes. All FeLV-positive animals were co-infected with feline hemoplasmas. To further characterize the Iberian lynx FeLV strain and evaluate its potential virul...

Canine distemper virus (CDV) is a morbillivirus that is the etiological agent of one of the most important viral diseases affecting canids and an expanding range of other carnivores. Using real-time RT-PCR, CDV RNA was detected in organs of an Iberian lynx (Lynx pardinus) found dead in the Doñana National Park, Southwestern Andalusia, Spain. This f...

Wild felids are considered important in maintaining the sylvatic cycle of Toxoplasma gondii. Although, T. gondii antibodies have been reported in several species of wild felids, little is known of the epidemiology and risk factors associated with T. gondii infection in wild cats. The Iberian lynx (Lynx pardinus) is the most endangered felid species...

The Iberian lynx (Lynx pardinus) is considered the most endangered felid species in the world. To date, less than 200 animals remain in the wild. Low numbers and genetic uniformity may contribute to render this species particularly susceptible to infectious diseases. Different pathogens have been identified in Iberian lynxes; including several feli...

The Iberian lynx (Lynx pardinus) is the most endangered felid in the world. Adequate genetic management of in situ and ex situ populations, and linkage between both, require knowledge on male reproductive biology and factors influencing it. We examined the influence of age, free-ranging versus captive conditions and seasonality on phenotypic, endoc...

Contents The Iberian lynx is considered the most endangered felid species. Therefore, an ex situ conservation program was initiated to protect this species from extinction. Additional knowledge on lynx reproduction biology and reliable methods for reproductive monitoring are important for developing a captive breeding program. The aim of this study...

The Iberian lynx (Lynx pardinus) is considered the most endangered felid species in the world. In order to save this species, the Spanish authorities implemented a captive breeding program recruiting lynxes from the wild. In this context, a retrospective survey on prevalence of selected feline pathogens in free-ranging lynxes was initiated. We syst...

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...

In order to determine the importance of various infectious agents as potential threats to Iberian lynx conservation, 77 free-ranging animals were screened for presence of 14 feline pathogens between November, 2003 and September, 2007. Evidence of presence of 13 out of 14 infectious agents was found: antibodies to feline calicivirus (FCV) were detec...

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...

Conservation actions for the endangered Iberian lynx require the integration of expertise and veterinary skills into an interdisciplinary effort. Veterinary actions are overseen by the Iberian Lynx Health Advisory Group (GAAS). These actions involve developing and implementing working protocols (manuals), anesthetizing animals, collecting samples,...

Biochemical reference intervals were determined for 31 clinically healthy Iberian lynxes (Lynx pardinus) between 1 and 6 years of age. Thirteen of the lynxes were wild-caught and the other 18 were captive-reared animals. The samples were collected between November 2004 and December 2006. The influence of sex (males vs. females), age (juveniles vs....

Early sibling fights in Eurasian and Iberian lynxes differ from other types of behavior in a lack of ritualized elements (threats) and a high motivation level. In 2005 sudden aggression, which ended up in siblicide, took place in the first Iberian lynx litter born in captivity. Fights became a problem, turning into one of the highest risks of morta...

Semen traits and factors affecting sperm cryopreservation were assessed in the Iberian lynx (Lynx pardinus), a species regarded as the most endangered felid in the world. For cryopreservation, semen was washed, resuspended in a Tes-Tris-based diluent (TEST) or a Tris-based diluent (Biladyl), both with 20% egg yolk and 4% glycerol, loaded into straw...

The Iberian Lynx Conservation Breeding Program follows a multidisciplinary approach, integrated within the National Strategy for the Conservation of the Iberian lynx, which is carried out in cooperation with national, regional and international institutions. The main goals of the ex situ conservation programme are to: (1) maintain a genetically and...

This work presents a Biological Resource Bank generated as a complementary supporting tool for the reproduction and the in situ and ex situ conservation of the Iberian lynx. In its design we prioritized the preservation of a maximum of the current genetic and biological diversity of the population, and the harmless collection of the samples. To pro...

The Iberian lynx is the most endangered felid species in the world, confined nowadays to two isolated metapopulations in the southwest of Spain, where less than 200 individuals survive. Little is known about the diseases that affect these animals in the wild or in captivity. Kidney samples from necropsies of 27 Iberian lynxes, wild and captive, wer...

An update on the 2007 breeding season of the Critically Enangered Iberian lynx, about the new Breeding Centre La Olivilla that was opened in Jaén, and about linking ex-situ and in-situ conservation efforts for the future of this species.

While hemoplasma infections in domestic cats are well studied, almost no information is available on their occurrence in wild felids. The aims of the present study were to investigate wild felid species as possible reservoirs of feline hemoplasmas and the molecular characterization of the hemoplasma isolates. Blood samples from the following 257 wi...
