Since the origin of early Homo species during Late Pliocene, interactions humans with scavenging birds and mammals have changed in form through shifting ecological scenarios. How procured meat Quaternary Period from confrontational to hunting; shepherding wild animals; and, eventually, intensive husbandry domesticated animals. As evolved carcass consumers providers, overall relationship between scavengers shifted competition facilitation. These changing translated into provisioning (by...
Background Urbanization is the most prevailing cause of habitat transformation worldwide, differing from others by its intense levels human activity. Despite obvious impact on wildlife, it still unclear why and how some species are able to adapt urban settings. One possibility that fear humans vehicles could preclude invading cities. Species entering environments might be those more tolerant disturbance (i.e., tame species). Alternatively or in addition, invaders a fraction variable species,...
The main objective of many conservation programs is to increase population size by improving a species' survival and reproduction. However, density dependence demographic parameters may confound this approach. In study we used 25-year data set on Bearded Vultures (Gypaetus barbatus) in Spain evaluate the consequences growth reproductive performance. Unlike its coefficient variation (cv), mean annual productivity decreased with increasing size. After controlling for territorial heterogeneity,...
Individuals often consistently differ in personalities and behaviours that allow them to cope with environmental variation. Flight initiation distance (FID) has been measured a variety of taxa as an estimate the risk individual is willing take when facing predator. FID used test life-history trade-offs related anti-predatory behaviour for conservation purposes such establish buffer zones minimize human disturbance, given its species-specific consistency. Individual consistency FID, however,...
Human-predator conflicts are directly or indirectly threatening many species with extinction. Thus, biologists urged to find simple solutions complex situations while avoiding unforeseen conservation outcomes. The provision of supplementary food at artificial feeding sites (AFS) is frequently used in the scavenger bird populations currently suffering from indirect poisoning, although no scientific studies on its effectiveness have been conducted.
Summary 1. Between 1996 and 2000 the appearance of bovine spongiform encephalopathy swiftly became one most serious public health political crises concerning food safety ever experienced in European Union (EU). Subsequent sanitary regulations led to profound changes management livestock carcasses (i.e. industrial destruction around 80% all animal carcasses), thereby threatening last remaining healthy scavenger populations Old World thus contradicting long‐term environmental policies EU. 2....
cological immunology requires techniques to reliably measure immunocompetence in wild vertebrates. The PHA-skin test, involving subcutaneous injection of a mitogen (phytohemagglutinin, PHA) and measurement subsequent swelling as surrogate T-cell mediated immunocompetence, has been the test choice due its practicality ease use field. However, mechanisms involved local immunological inflammatory processes provoked by PHA are poorly known, interpretation an acquired immune response is currently debated.
Chance per se plays a key role in ecology and evolution, e.g., genetic mutation, resource spatiotemporal unpredictability. In community ecology, chance is recognized as factor assemblage, but less known about its intraguild processes leading to species coexistence. Here we study the relevance of unpredictability promoter positive interspecific interactions biodiversity enhancer an Old World avian scavenger guild, which has evolved feed upon spatially temporally unpredictable resources, i.e.,...
Abstract Effective prevention and control of invasive species generally relies on a comprehensive, coherent representative list that enables resources to be used optimally. European Union (EU) Regulation 1143/2014 alien (IAS) aims or eradicate priority species, manage pathways prevent the introduction establishment new IAS; it applies considered concern subject formal risk assessment. So far, 49 have been listed but criteria for selecting assessment not disclosed were probably unsystematic....
Addressing the challenge of photovoltaic growth: Integrating multiple objectives towards sustainable green energy development,
Invasive species can take advantage of resources unexploited by natives (opportunism hypothesis) or they exploit the same but more aggressively efficiently (competition hypothesis), thus impacting native species. However, invasive tend to anthropogenic habitats that are inefficiently used such as urban environments. Focusing on ring-necked parakeet (Psittacula krameri), one most birds worldwide, we combined observations interspecific aggressions, species-specific cavity-nest preferences and...
The identification of effects invasive species is challenging owing to their multifaceted impacts on native biota. Negative are most often reflected in individual fitness rather than population dynamics and less expected low-biodiversity habitats, such as urban environments. We report the long-term rose-ringed parakeets largest known a threatened bat species, greater noctule, located an park. Both share preferences for same tree cavities breeding. While number parakeet nests increased by...
Quantifying space use and segregation, as well the extrinsic intrinsic factors affecting them, is crucial to increase our knowledge of species-specific movement ecology design effective management conservation measures. This particularly relevant in case species that are highly mobile dependent on sparse unpredictable trophic resources, such vultures. Here, we used GPS-tagged data 127 adult Griffon Vultures Gyps fulvus captured at five different breeding regions Spain describe patterns...
Density‐dependent breeding performance due to habitat heterogeneity has been shown regulate populations of territorial species, since the progressive occupation low quality territories as density increases may cause a decline in mean per capita fecundity population while variation increases. Although preemptive use sites relegate individuals progressively lower suitability, few studies on dependence have tried separate effects territory from individual quality, and none simultaneously...
Despite its key role in population dynamics and evolutionary ecology, little is known about factors shaping survival long-lived territorial species. Here, we assessed several hypotheses that might explain variability a migratory Spanish of species, the Egyptian vulture Neophron percnopterus, using 16-year monitoring period live-encounter histories 835 individually marked birds. Cormack-Jolly-Seber capture-recapture models showed no evidence for effects sex or nestling body condition on...
Abstract Understanding the factors underlying species coexistence is a major focus in community ecology. When dealing with competition between native and exotic species, competitive exclusion of ‘weaker’ can have consequences for biodiversity conservation. We examined interspecific interactions during foraging black vultures Coragyps atratus Andean condors Vultur gryphus Southern Argentina. Previous studies suggest facilitatory them. However, most parts their distribution ranges, these did...
