“…The ibex population of the Natural Park of Sierra Nevada is very dense and larger than other populationsvalues ranged between 6.5 and 8.2 animals/km 2 until 2000 (Pé rez et al, 2002). Of the three metapopulations of C. pyrenaica included in this study, the Sierra Nevada metapopulation is the most genetically diverse (Manceau et al, 1999). This metapopulation maintains seven of the 10 haplotypes that characterize the Andalusian populations (Pé rez et al, 2002); the population from Malaga and Cadiz, which were included in the metapopulation Sierras de Má laga, only maintains two of the 10 haplotypes.…”

ABSTRACT:Mycoplasma agalactiae is the main causal agent of contagious agalactia syndrome in Spain. It is a severe disease of small ruminants, endemic in Mediterranean countries, that is characterized by mastitis, arthritis, and keratoconjunctivitis. This paper investigates the temporal, spatial, and host-related factors in the distribution of M. agalactiae infection from October 1996 to November 1998 and March 2002 to May 2003 in Spanish ibex (Capra pyrenaica) populations from Andalusia, in southern Spain. The predisposing factors to infection among previously selected factors (year of sampling, climatic season, geographic origin according to province, mountain range and metapopulation, sex, year of life, presence of scabies, and phase of the reproductive cycle) were established. We collected conjunctival and ear-canal swabs from 411 free-ranging ibexes. The frequency of infected ibexes was 11.2%. The peak frequency of infection occurred in 1998 and in summer. Granada was the province with greatest risk (odds ratio52.6) of carriers (18.8% infected). The predisposing factors were sex (females), age (young animals), and metapopulation (Sierra Nevada). We identified a higher number of infected ibexes in the metapopulation ''Sierra Nevada'' (34/ 256) and significant differences among the three established metapopulations (P,0.01). Mycoplasma agalactiae infection represents a risk for population density and maintenance of these wild populations; infections can result in blindness, malnutrition, and polyarthritis leading to numerous deaths.

“…Sequence analysis of the SI mitochondrial control and cytochrome b gene regions by Manceau et al (1999) demonstrated that the level of divergence between CPP and the other two extant SI subspecies was almost as high as the divergence between the SI and the Alpine ibex. We hypothesize that the recent extinction of the CPP subspecies might have involved a marked reduction in the allelic pool of the Capy-DRB1 and other MHC genes.…”

Low diversity in the major histocompatibility complex class II DRB1 gene of the Spanish ibex, Capra pyrenaica

During the last two centuries, the Spanish ibex (Capra pyrenaica) has shown a significant demographic decline as a result of the progressive destruction of its natural habitat, disease epidemics, and uncontrolled hunting. Partial sequencing of the class II MHC DRB1 gene revealed that the Spanish ibex has remarkably low levels of genetic variation at this locus, with only six different DRB1 alleles and an observed heterozygosity of 0.429-0.579. The rates of nonsynonymous vs synonymous substitutions were significantly different in the peptide-binding region (d N /d S ¼ 5.347, P ¼ 0.002), a feature that indicates that the DRB1 gene is under positive selection. A phylogenetic analysis of the Spanish ibex and a set of domestic goat DRB1 alleles revealed that the reported sequences represent four major allelic lineages. The limited allelic repertoire of the DRB1 gene in the Spanish ibex is likely the direct result of the recent history of population bottlenecks and marked demographic decline of this species. A genetic survey of 13 microsatellite loci was consistent with this idea. The Spanish ibex subspecies C. p. hispanica and C. p. victoriae consistently showed considerably lower levels of microsatellite heterozygosity (H o ¼ 0.184-0.231) and allelic diversity (mean number of alleles per locus ¼ 2-2.4) than those reported in other wild ruminants. This study demonstrates the significance of both natural selection and the demographic history of populations in determining patterns of genetic variation at MHC loci. In addition, our results emphasize the importance of locally adapted populations for the preservation of genetic diversity.

“…Nevertheless, the coexistence of a small population of Iberian wild goat and a large population of feral goats is a situation that should be monitored closely. The existence of this population, which originated from an unintentional escape, does not follow IUCN standards for re-introductions (2012), and belongs to a population that is genetically distant from the extinct Pyrenean wild goat (Manceau et al 1999). Thus, monitoring should continue, along with the study of this population's interactions with feral domestic goats; furthermore, its future must be decided as soon as possible, considering eradication or restocking .…”

An escaped herd of Iberian wild goat (Capra pyrenaica, Schinz 1838, Bovidae) begins the re-colonization of the Pyrenees Abstract: In January 2000, the last Pyrenean wild goat, Capra pyrenaica pyrenaica, died in Ordesa National Park in the Spanish Pyrenees. Since that time, there has been an intense debate over the possibility of using individuals from other extant subspecies to restore the Iberian wild goat C. pyrenaica in the Pyrenees. In the late 1990s, some Iberian wild goats of the hispanica subspecies escaped from an enclosure in Guara Nature Park, also in the Spanish Pyrenees. Between 2006 and 2012, four annual counts were conducted to quantify the demographics of the population. This expanding but isolated population numbered at least 86 free-living Iberian wild goats in 2012, reproducing in the wild with a positive increasing trend (λ = 1.067). Given the small number of original animals that escaped, new releases are necessary to insure the genetic variability of the small population, but only if a clear decision on its conservation is finally made. In addition, the population is sympatric with a population of several hundred feral goats, C. hircus, which should be monitored closely, in order to detect any problems with competence or hybridization, although the latter has not been demonstrated in the wild.
