Trichinellosis is a notifiable zoonotic disease caused by parasitic nematode larvae belonging to the genus Trichinella. Domestic pig and wild boar are important hosts within the natural cycle of T. spiralis, the last one being an animal whose populations have experienced an important growth. Therefore, this paper studies the prevalence of Trichinel...

Urbanization creates new ecological conditions that can affect biodiversity at all levels, including the diversity and prevalence of parasites of species that may occupy these environments. However, few studies have compared bird–ectoparasite interactions between urban and rural individuals. Here, we analyze the ectoparasite community and co-infect...
Article
Sarcoptic mange affects mammal host species worldwide and, particularly, wild Caprinae throughout much of Eurasia. In the Iberian Peninsula, several outbreaks of sarcoptic mange in Iberian ibex (Capra pyrenaica) have been reported since the 1980s. Using data from a period of long‐term monitoring and a seasonal autoregressive integrated moving avera...

Article
Specific identification of oestrid larvae is usually problematic not only when using morphobiometric features, but also when applying molecular criteria, since very few molecular markers have been described for this group of flies. New molecular markers for oestrid are needed for more reliable species identification, diagnostic purposes, and epidem...
Article
We analysed the diversity of the cytochrome b gene in Iberian ibex (Capra pyrenaica) populations in the southern Iberian Peninsula by sequencing a fragment (987 bp) of this gene in 347 ibex from 10 population nuclei in Andalusia. We found 25 different haplotypes, which account for 64.10% of all haplotypes thus far described for the species (n = 39)...
Article
In most unisexual species, the numbers of male and female individuals are approximately equal. The adult sex ratio (ASR) is a key demographic parameter for the conservation and management of wild species. However, in the case of monomorphic birds such as the Rock Ptarmigan Lagopus muta, estimating the sex ratio is difficult. To test if the sex rati...

Cephenemyia stimulator and Oestrus ovis are two important parasitic bot flies (Oestridae) species causing myiasis, with a potential negative impact on the welfare of the host. Using next-generation sequencing approach and bioinformatics tools, a large panel of possible microsatellites loci was obtained in both species. Primer pairs were designed fo...
Article
Sarcoptic mange is a cosmopolitan disease affecting the skin of domestic and wild mammalian species and humans as well. In Eurasia, sarcoptidosis (also known as sarcoptic mange or scabies) affects mountain ungulates (Caprinae) among other wild hosts, and epizootic outbreaks induce variable mortality rates. This fact, coupled with the important ecol...

Size‐selective harvesting of wild ungulates can trigger a range of ecological and evolutionary consequences. It remains unclear how environmental conditions, including changes in habitat, climate, and local weather conditions, dilute or strengthen the effects of trophy hunting. We analyzed horn length measurements of 2,815 male ibex (Capra pyrenaic...
Article
Background: Acute phase protein (APP) concentrations can change due to inflammation and be used to monitor disease in the Iberian ibex (Capra pyrenaica). Objectives: This study aimed to validate Haptoglobin (Hp) and serum amyloid A (SAA) analytes, establish reference values, and characterize Hp and SAA responses in the Iberian ibex after experim...
Conference Paper
Despite the variety of existing methods to assess the population size of mountain ungulates, their accuracy has rarely been tested on known-size populations. In this study, we took advantage of 27 surveys of a captive Iberian ibex (Capra pyrenaica) herd to evaluate the systematic detection error associated with the whole population and sex-specific...
Conference Paper
Intense and deregulated trophy hunting can trigger phenotypic and evolutionary trait changes in wild bovids (Coltman et al., 2003; Pigeon et al., 2016), however it remains largely unexplored how individual performance, population structure and composition, as well as a multitude of environmental factors, including climate and habitat changes, weake...

One of the main objectives of community ecology is identifying how co-occurring species use and share space and resources. Species of the same trophic level, such as large herbivores, are of fundamental interest in that context because competition for resources is likely. Segregation in space or on some axes of the ecological niche are processes al...

The Iberian ibex, Capra pyrenaica, is a highly valued big game species in the Iberian Peninsula. Despite many studies have focused on its biology and ecology, very few have addressed its exploitation through hunting, generally focusing on the temporal evolution of trophy size only. The main goal of our study is to estimate the annual collection quo...
Article
In this study we have monitored the stress of Iberian ibex at individual level within the course of an experimental infection with Sarcoptes scabiei mites. For this purpose we have measured faecal 11-ketoetiocholanolone (11-k)using high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). We used linear mixed models...
