“…We have undertaken a population genetic analysis of the MHC DRB1 gene in the Spanish ibex (Capra pyrenaica), a wild goat species distributed throughout the South-Eastern mountains and the Gredos and Batuecas mountain ranges of Spain (Pérez et al, 2002). Four different subspecies of Spanish ibex (SI), C. p. hispanica (CPH), C. p. victoriae (CPV), C. p. pyrenaica (CPP) and C. p. lusitanica (CPL), were originally characterized on the basis of horn morphology, coat colour and other phenotypic features (Cabrera, 1911).…”

“…Disease epidemics, uncontrolled hunting, overgrazing, and progressive destruction of natural habitats likely played an important role in the marked demographic decline of the SI. Although current estimated population sizes of SI are fairly large in certain areas, for example, 14 000 individuals in the Sierra Nevada population, the occurrence of severe demographic bottlenecks during the 19th and 20th centuries, with effective sizes ranging from 5 to 100 individuals, is well documented (Crampe, 1991;Manceau, 1997;Pérez et al, 2002).…”

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.

“…In some regions of Spain, some populations of wild ungulates expanded between the mid of the 19th C. and the mid-20th C (Madoz 1856, Sáenz de Buruaga, 1987, Gortázar et al 2000, as well as in recent decades (Pérez et al 2002). Expanding ungulate populations have led to increases in crop damages (Herrero et al 2006), automobile accidents (Lagos et al 2012), the human consumption of game, the prey availability to endangered large carnivores (Blanco et al 2011), disease transmission (Armenteros et al 2013), and changes in the composition and abundance of plant species in natural and seminatural ecosystems (Wilson 2004, Bueno et al 2012) because of their diet, which has affected other species (Apollonio et al 2010, Barrios-García & Ballari 2012.…”

To update the information on the distributions of wild ungulates in Aragon, Spain, populations were surveyed based on questionnaires sent to rangers of the Government of Aragon. The data were analyzed in two five-year periods: 2001-2005 and 2006-2010. Our analysis was based on the 242 and 278 questionnaires, corresponding approximately with 80-90% answers that were analyzed in 2006 and 2011, respectively. The survey documented the presence/absence of up to eight wild ungulate species within a UTM 10x10 km grid on maps that were specific to the counties in which the rangers worked. In 2006-2010, wild boar Sus scrofa was the most widely distributed species as it occurred in all of the grid blocks. Roe deer Capreolus capreolus were documented in 89% of the grid blocks, Iberian wild goat Capra pyrenaica in 37%, red deer Cervus elaphus in 31%, Pyrenean chamois Rupicapra p. pyrenaica in 10%, feral goat Capra hircus in 8%, fallow deer Dama dama in 3%, and mouflon Ovis aries in 0.3%. The Pyrenees had the highest and the Middle Ebro Valley had the lowest diversity of ungulates. In the Iberian System, diversity was intermediate. Overall, the distribution of ungulates increased 21% between the two periods. Feral goat populations expanded the most (111%), although Iberian wild goat (61%), roe deer (50%), and red deer (4%) also expanded. The range of wild boar populations remained stable, but the ranges of chamois and fallow deer populations were reduced 6%. By 2010, typically, in most block grids three or more species of wild ungulates coexist. We recommend that ungulate populations in Aragon be surveyed at least every five years.

ResumenCon el fin de actualizar la distribución de los ungulados silvestres en Aragón, se realizaron encuestas a los Agentes de Protección de la Naturaleza del Gobierno de Aragón en dos periodos: 2001-2005 y 2006-2010. Se recibieron un total de 242 y 278 respectivamente, correspondientes a un 80-90% de respuestas y que se analizaron en 2006 y 2011 respectivamente. Las encuestas documentaron la presencia/ausencia de hasta ocho especies de ungulados silvestres en cuadrículas UTM 10 x 10 km. En 2006-10, el jabalí Sus scrofa es la especie con una mayor distribución, ocupando la totalidad de las cuadrículas. El corzo Capreolus capreolus ocupó el 89% de las cuadrículas, la cabra montés Capra pyrenaica el 37%, el ciervo Cervus elaphus el 31%, el sarrio Rupicapra p. pyrenaica el 10%, la cabra doméstica asilvestrada Capra hircus el 8%, el gamo Dama dama el 3% y el muflón Ovis aries el 0,3%. Las zonas con mayor riqueza de ungulados se encuentran en el Pirineo, y los de menor con el Valle Medio del Ebro, siendo el Sistema Ibérico el que tiene una riqueza intermedia. En conjunto los ungulados han aumentado en un 21% su distribución entre los dos periodos, siendo el de mayor crecimiento la cabra doméstica asilvestrada (111%), seguido de la cabra montés (61%), corzo (50%) y ciervo (4%). La distribución del jabalí se ha mantenido y la del sarrio y el...

1. Monitoring trends in animal populations is essential for the development of appropriate wildlife management strategies. However, long-term studies are difficult to maintain mainly due to the lack of continuous funding. In this scenario, the collaboration between local stakeholders and researchers can be a fruitful partnership to monitor game species for long periods and vast territories.2. We present an experimental framework with the involvement of researchers, local hunters and game managers for the continuous monitoring of wild ungulate populations. By combining vehicle-based counts with distance sampling techniques, we implemented and validated a sampling scheme able to provide demographic information for the effective management of wild ungulate populations. Here, we used an Iberian red deer (Cervus elaphus) population as a model.3. The project implementation involved 30 participants including 24 stakeholders and 6 field technicians/data analysts with experience in monitoring wild ungulates. A total of eight teams covered 29 itineraries, synchronously, in two periods of ecological relevance for red deer, early summer and early autumn. Density estimates were consistent among sampling periods and characterized by acceptable coefficients of variation (approximately 20%). Our results prove that the application of the proposed framework is feasible (three to four itineraries per team), cost-and time-effective (one week per sampling period) and produce population estimates fit for management. Being based on direct observations, the method would provide important demographic indicators (e.g. population density, age structure and fawn recruitment, and group size) about wild ungulate populations. 4. Apart from engaging interested stakeholders, the success of our proposal relies on three key actions including the theoretical and field instruction of participants, the definition of timely and unbiased survey designs and the maintenance of participants' motivation. The implementation of rigorous and standardized sampling protocols is pivotal for data integration through time and space.
