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...

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...

Background Sarcoptic mange is one of the main parasitic diseases affecting the Iberian ibex Capra pyrenaica. Scabietic animals suffer a decline in body condition and reproductive fitness and in severe cases may die. Although several previous studies of the pathology of this disease and the physiological changes it produces in ibex have been carried...

Extraction and mineral processing, as well as the waste generated by old abandoned mining sites, are the main sources of contamination of water bodies and lands by potentially toxic elements (PTEs). The common carp (Cyprinus carpio Linnaeus 1758) has been reported to be a good ecological indicator of environmental pollution in water bodies. Hence,...

Deer hunting has traditionally had great relevance due to the diversity of resources obtained from it, such as meat. Our aim has been to analyse the total post-mortem weight, dressed carcass weight and carcass yield, as well as their variations as a function of years, sex, age and hunting season (autumn vs. winter). Also, predictive equations for c...

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...

Chapter
In this article, the graphical exploratory tool SiZer Map is constructed for the inference of the rate of occurrences of events that follow a nonhomogeneous Poisson process. SiZer Map is defined considering nonparametric local linear kernel estimators for the rate function and its first derivative. The bandwidth parameter is the viewing scale, and...

Faecal cortisol metabolite (FCM) analysis is a reliable non-invasive method used in field endocrinology studies to assess levels of stress in animals. It is known that weather and, above all, humidity, can affect FCM concentrations in faecal samples. In addition, the prolonged storage of samples and delay in their analysis may alter metabolite conc...

Mandibles from separate populations of free-living mouflons (Ovis aries musimon) from Southern Spain, submitted to different ecological conditions, were studied. Searching for ontogenetic shape variations we used geometric morphometrics tools and we explored the use of several mathematical models for describing growth rate variations between popula...
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...
Article
The objective of this paper is to find out possible patterns of failure occurrences in a repairable system. We develop a graphical exploratory tool and perform visual inference considering non‐parametric local linear kernel estimators for the rate of occurrence of failures (ROCOF) and its first derivative. The shape characteristics of the ROCOF fun...

ABSTRACT Wild boar (Sus scrofa) has become in one of the most abundant and widely distributed big game hunting species in our country, causing important agricultural, ecological and urban damages in the last years. This research evaluates its demographic growth considering the official hunting data gathered during a period of ten years from five...
Thesis
This thesis analyzes the density and the population size fluctuations of two deer species in Mediterranean ecosystems during almost two decades. The main objective is to assess the relative effect of hunting, climate and density on the population size fluctuations of two species sympatric deer, red deer (Cervus elaphus hispanicus) and fallow deer (...
Article
Detecting density-dependence (DD) in population fluctuations is essential for population control, herd management and harvest programs. However, little information has been obtained for deer in Mediterranean ecosystems. We assess the effects of density, climate and harvesting on population growth fluctuations of two sympatric red (Cervus elaphus hi...
Thesis
Esta tesis doctoral se centra en el uso de modernos métodos estadísticos para evaluar las características de funcionamiento de un sistema de fiabilidad dinámico que opera bajo ciertas condiciones y que evoluciona aleatoriamente en el tiempo. En concreto, se proponen nuevos modelos estocásticos que permiten relacionar las medidas de funcionamiento...
Article
A nonparametric accelerated failure time (AFT) model is considered to evaluate the dependability measures of a water supply system laid in a city of the Mediterranean Sea. To do it, a set of breakdown data of sections of pipe of the system is available. Unlike the usual methods that assume a parametric family for the underlying lifetime, we propose...
