Birds of prey have been, in comparison to other avian groups, an uncommon study model, mainly due the limitations imposed by their conservative life strategy (low population density and turnover). Nonetheless, they attracted a strong interest from point view conservation biology because many populations been close extinction recognised role ecosystems as top predators scavengers flagship species. Today, after more than century persecution, with exception some vultures still very much...
Electrocution by power lines is one of the main causes non-natural mortality in birds prey. In an area central Spain, we surveyed 6304 pylons from 333 to determine electrocution rates, environmental and design factors that may influence efficacy mitigation measures used minimise cases. A total 952 electrocuted raptors, representing 14 different species, were observed. Electrocuted raptors concentrated certain areas associated with increased events were: greater numbers prey animals;...
Global warming due to human-induced increments in atmospheric concentrations of greenhouse gases (GHG) is one the most debated topics among environmentalists and politicians worldwide. In this paper we assess a novel source GHG emissions emerged following controversial policy decision. After outbreak bovine spongiform encephalopathy Europe, sanitary regulation required that livestock carcasses were collected from farms transformed or destroyed authorised plants, contradicting not only...
Abstract Understanding the movement of threatened species is important if we are to optimize management and conservation actions. Here, describe age sex specific spatial temporal ranging patterns 19 bearded vultures Gypaetus barbatus tracked with GPS technology. Our findings suggest that asymmetries a consequence breeding status age-classes. Territorial individuals exploited home ranges about 50 km 2 , while non-territorial birds used areas around 10 000 (with no seasonal differences). Mean...
The mechanisms that determine the evolutionary adaptations of scavengers to carrion exploitation have been well established. In contrast, little is known about coexistence during based on behavioral traits and considering obligate facultative species together. This study revisits hypotheses organization within guild necrophagous birds in light adaptive processes specialization exploitation. We used a detailed dataset observations from high-quality video recordings 2 regions with most diverse...
Summary Protected areas are one of the most common strategies for wildlife conservation world‐wide. However, their effectiveness is rarely evaluated. In Europe, after outbreak bovine spongiform encephalopathy, a restrictive sanitary regulation ( EC 1774/2002) prohibited abandonment dead livestock in extensive farming (extensive livestock) field, which led to negative consequences scavengers. As an attempt mitigate this impact, new was approved 142/2011) allow farmers leave carcasses...
Abstract Competition for limiting natural resources generates complex networks of relationships between individuals, both at the intra- and interspecific levels, establishing hierarchical scenarios among different population groups. Within obligate scavengers, especially in vultures, coevolutionary mechanisms operating during carrion exploitation are highly specialized determined part by agonistic behavior resulting intra-guild hierarchies. This paper revisits behavioral organization within...
Symbionts are key elements of ecosystems, by playing important roles in shaping the biology and ecology their hosts. However, factors determining symbiont loads across host species still unclear. Nowadays, we know that intensity prevalence feather mites, most diverse group avian ectosymbionts, differ strongly between species. To understand those differences, studied 17 bird traits two mite community features (species richness composition species) potentially related to interspecific...
Tagging wildlife with transmitters is one of the most widely used techniques for research and monitoring. Knowing possible impact attaching to an animal has always concerned researchers; however, assessments have been directed at effects on behaviour fitness, fewer addressed injuries individuals. The present study evaluated physical status birds tagged mounted a Garcelon‐type backpack harness, from five species large medium‐sized soaring raptors in western Europe. also assessed factors...
The capercaillie Tetrao urogallus - the world's largest grouse- is a circumboreal forest species, which only two remaining populations in Spain: one Cantabrian mountains west and other Pyrenees further east. Both have shown severe declines, especially population, has recently been classified as "Critically Endangered". To develop management plans, information on demographic parameters necessary to understand forecast population dynamics. We used spatial capture-recapture (SCR) modeling...
ABSTRACT The European wild rabbit ( Oryctolagus cuniculus ) has suffered a dramatic reduction in numbers many parts of the Iberian Peninsula over past 50 years. is keystone species Mediterranean ecosystems and an important game resource. Because its role as prey animal, it for preservation globally threatened predators. Several techniques have been used to help populations recover. Restocking one most because frequent use throughout rabbit's range. In present study, we analyzed population...
Despite the consensus among ecologists and conservationists of importance maintaining scavenger feeding patterns based primarily on natural prey sources, human‐mediated remains a widely used management tool for threatened wildlife. Thus, it is important to understand key factors favoring certain species age‐groups at supplementary sites. Through detailed videomonitored experiment carrion inputs different locations in Iberian Peninsula (home >90% European vultures), we assessed how...
Abstract We studied the factors that determine presence of cinereous vulture Aegypius monachus at 134 carcasses experimentally distributed in Special Protection Areas for Birds (SPA) western and central Spain. Our goals were to assess use these by‐products order find out vulture's food preferences thus provide recommendations management specific restaurants this species. results suggest number vultures come feed on is related quantity biomass present types pieces provided food. Cinereous...
Limitation of disturbing activities around the breeding areas protected species is not always possible, if these are economically important and have, in addition, positive effects on protecting habitats those species. Searching for optimal solutions making commercial exploitation natural resources compatible with biodiversity conservation thus concern to managers policy makers. This case cinereous vulture Aegypius monachus, primarily cork-oak woodland, cork exploitation, a traditional...
Carrion provides energy transfer to food webs as a primary trophic resource for many taxa. Ecological relationships around this pulsed are highly complex and influenced by factors, including those related its availability the management of carcasses humans. In recent years progress has been made in understanding scope, implications value carrion ecology, mainly using scavenger birds arthropods study models. However, is important other facultative scavengers, even non‐scavenger species, which...
Interaction with man-made infrastructures is one of the main sources non-natural bird mortality. Here, we use a long-term study (1980–2010) to analyse spatial and temporal patterns in avian electrocution Spain, using ringed birds as well published reports articles information sources. Electrocution rates differ from obtained unringed species. are likely seasonally asymmetrical not constant across periods: between 1990 2005 an annual rising trend 5% was observed, whereas 2006 2010 this...
Understanding why host species differ so much in symbiont loads and how this depends on ecological traits is a major issue the ecology of symbiosis. A first step inquiry to know whether observed differences among are species-specific or more related with host-symbiont environmental conditions. Here we analysed repeatability (R) intensity prevalence feather mites partition within- among-host variance components. We compiled largest dataset far available: 119 Paleartic passerine bird species,...
Mesopredator control has long been used to alleviate the effect of elevated predation pressure on vulnerable, threatened or valuable species. However, convenience using mesopredator controls is technically questionable and scientifically-sound research therefore required evaluate impact prey case by case. In this study we evaluated alteration terrestrial dynamics demographic parameters a relict capercaillie Tetrao urogallus aquitanicus population currently in decline for which not previously...
