The influence of short- and long-term (cohort) effects of climate and density on the life-histories of ungulates in temperate regions may vary with latitude, habitat, and management practices, but the life-histories of ungulates in the Mediterranean region are less well known. This study examined the short- and long-term effects of rainfall and absolute(More)
Every year, about three million farm-reared red-legged partridges are released in Spain for hunting purposes, most of them for restocking where the success is very low. Some factors such as the sudden shift from abundant commercial energy-rich diet to natural food and absence of experience at looking for natural food resources could cause a rapid physical(More)
1. Haematological and plasma biochemical parameters of 66 captive red-legged partridges (Alectoris rufa) of both sexes were analysed in order to determine reference values, taking sex and age into account. 2. There were no statistically significant differences in haematocrit, plasma glucose content or creatine kinase activity either with age or between(More)
Extensive farming practices and landscape heterogeneity promote biodiversity in agroecosystems. However, the effect of such practices might be landscape dependent; specifically, the effect might be greatest where the loss of heterogeneity has been the largest. In recent decades, agricultural intensification and landscape simplification have dramatically(More)
Olfactory signalling is widespread among mammal inter- and intra-specific communication systems. Social mammals use latrines (faecal accumulations) as a communication system, which address the needs of individuals both inside and outside the social group. Latrines are commonly used as olfactory and visual signals for the delimitation of territories, and the(More)
Over the past few decades, the wild boar has been undergoing an expansion in Europe, which may have negatively affected small game populations and particularly red-legged partridges. We aim to evaluate the red-legged partridge nest predation by wild boar at high boar abundances by placing artificial nests in nine big game estates. Predation rates were(More)
About half a million rabbits are translocated in southwestern Europe every year for conservation and hunting purposes. However, the success of traditional rabbit restocking is generally extremely low, and this has been attributed to short-term predation by mammalian carnivores. Hence, recent recovery programs have tackled the problem of terrestrial(More)
The wild boar has, over the past few decades, undergone an expansion in Europe, which may have negatively affected ground-nesting bird populations and particularly those of wading birds. The aim of this study was to evaluate predation on waders’ nests by wild boar in Sweden, where this species has been increasing since its reintroduction. This was done by(More)
Resumen: La investigación sobre las características subya-centes del proceso hipnótico se ha caracterizado histórica-mente por ser muy controvertida debido, entre otras cues-tiones, a que la mayoría de los investigadores se adscriben a dos concepciones o paradigmas distintos sobre la naturale-za de la hipnosis: (1) el paradigma tradicional, que presupo-ne(More)
Understanding how non-invasive indicators of diet quality, such as faecal nitrogen (FN), relate to population performance is a valuable asset when assessing the management of wild ungulates. However, the relationships between FN and protein intake may depend on the ingestion of less palatable plants containing high quantities of tannin (which is known to(More)
