Introduction
My research interest focuses on the ecology and conservation of birds, especifically how populations face global change. I have been working for years on: 1) habitat selection, demographic components, population modelling, regulation processes, and intra and interspecific competition in raptors; 2) factors facilitating biological invasions (current exotic avian invaders but also native urban invaders) and their consequences; 3) conservation of parrots in the Neotropics (poaching, habitat)

Survival is a key demographic parameter for long‐lived bird species as it strongly influences their population dynamics and persistence. In recent decades, several studies have focused on unravelling differential patterns of survival by sex or age in bird populations, as each group may be affected by different ecological and anthropogenic pressures...
Understanding the movements and mortality of individuals across different life stages is crucial for the effective conservation of wild populations. We used data from 32 Egyptian vultures (Neophron percnopterus) tagged with GPS transmitters as nestlings in three Iberian breeding areas to study their dependence period, migration routes, movements in...
Natal dispersal is a critical trait for individual fitness and the viability, structure and genetic identity of populations. However, there is a pronounced information gap for large and long-lived species due to the difficulty of monitoring individuals at appropriate spatio-temporal scales. Here we study how individual traits and social and environ...
Zoonoses constitute a major risk to human health. Comprehensive assessments on the potential emergence of novel disease outbreaks are essential to ensure the effectiveness of sanitary controls and to establish mitigating actions.
Through a continental‐scale survey of rural human settlements conducted over 13 years in 15 Neotropical countries, we do...
18 Pharmaceutical contaminants have a recognized negative impact on wildlife health. 19 However, there are still many knowledge gaps on the factors influencing exposure and 20 metabolic processing of compound mixtures as a function of season and individual 21 characteristics such as age and sex. We evaluated age and sex differences in a set of 22 s...
The delimitation of African wintering areas of the griffon vulture Gyps fulvus has been established on the basis of ring recoveries, usually from dead individuals and, to a lesser extent, by reading ring and wing marks in human-populated areas. After GPS-tracking of several juvenile griffon vultures from central Spain, we show that a female used an...
The ongoing demand for renewable energy has boosted the development of wind farms worldwide. Given the impact these facilities have on flying species, a spatially explicit assessment of collision risk in vulnerable species is needed to guide management actions and prioritise areas for installing these infrastructures. We used GPS-tracking data of 1...
Natal dispersal is a critical trait for individual fitness and the viability, structure, and genetic identity of populations. However, there is a pronounced information gap for large and long-lived species due to the difficulty of monitoring individuals at appropriate spatio-temporal scales. Here we study how individual traits and social and enviro...
Variation in offspring sex ratio has been studied quite thoroughly in birds, but little attention has been paid to vultures, and particularly no research addressing differences between mainland and island populations has been done. Here, we took advantage of long-term monitoring programs in some of the most important colonies of Egyptian vultures i...

Parrots are among the most diverse and widely distributed groups of birds and one of the most threatened bird orders mainly due to habitat loss and illegal poaching. Most parrots are obligate cavity nesters, so the logging of mature trees and the transformation of natural cliffs represent important threats to their conservation. Here, we report nov...
Invasive alien species have widespread impacts on native biodiversity and ecosystem services. Since the number of introductions worldwide is continuously rising, it is essential to prevent the entry, establishment and spread of new alien species through a systematic examination of future potential threats. Applying a three-step horizon scanning con...
Variation in offspring sex ratio, particularly in birds, has been frequently studied over the last century, although seldom using long-term monitoring data. In raptors, the cost of raising males and females is not equal, and several variables have been found to have significant effects on sex ratio, including food availability, parental age, and ha...
Urbanization has reshaped ecosystems and changed natural processes, driving an intense transformation of biomes, biotic community composition and diversity. Despite the growing interest in studying urban ecology over the last decades, the consequences of these changes on species occupying these ecosystems are not yet fully understood. Trophic gener...
Illegal wildlife trade remains highly active in the Neotropics, as indicated by the thousands of parrots annually sold in illicit city markets. However, little is known about where parrots are poached, whether certain parrot species are selected among those available in the wild, their trade routes, and potential conservation impacts. We conducted...
Quantifying space use and segregation, as well as the extrinsic and intrinsic factors affecting them, is crucial to increase our knowledge of species-specific movement ecology and to design effective management and conservation measures. This is particularly relevant in the case of species that are highly mobile and dependent on sparse and unpredic...
Article reference: Morant et al. (2022). Large-scale movement patterns in a social vulture are influenced by seasonality, sex, and breeding region.

This is particularly relevant in the case of species that are highly mobile and dependent on sparse and unpredic...
Roads have multiple impacts on wildlife, but several species have been described to benefit from these infrastructures for different purposes, from movement to foraging. In some cases, roads can provide a limiting resource, determining then a population spreading along road proximities. However, these processes have been rarely described, and the p...

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...
Aim
Concern about the impacts of biological invasions has generated a great deal of interest in understanding factors that determine invasion success. Most of our current knowledge comes from static approaches that use spatial patterns as a proxy of temporal processes. These approaches assume that species are present in areas where environmental co...
There is broad consensus that increasing the use of renewable energies is effective to mitigate the global climate crisis. However, the development of renewables may carry environmental impacts, and their expansion could accelerate biodiversity loss (1). However, Dunnett et al. (2) have recently estimated a minimal overlap between renewable energy...
Variation in offspring sex ratios is a central topic in animal demography and population dynamics. Most studies have focused on bird species with marked sexual dimorphism and multiple-nestling broods, where the offspring sex ratio is often biased due to different individual or environmental variables. However, biases in offspring sex ratios have be...

Parrots (Psittaciformes), with about 400 species widely distributed across continents and oceanic islands, stand out among birds for their poor conservation status [...]
Wildlife trade is a major driver of biodiversity loss worldwide. To regulate its impact, laws and regulations have been implemented at the international and national scales. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) has regulated the international legal trade since 1975. However, an important volume...
Palms, like all plants, show coevolutionary relationships with animals that have been traditionally categorized as mutualistic (seed dispersers and pollinators) or antagonistic (seed predators). This dual perspective, however, has prevented a full understanding of their true interactions with some animal groups, mainly those that do not ingest enti...
Anthropogenic stressors can favor the occurrence of non-infectious disease that can be worsened by the impact of opportunistic pathogens, making the epizootiology of environmental diseases difficult to unravel. The incidence and impact of oral lesions in nestlings of a facultative scavenger species, the black kite Milvus migrans, were examined over...
The transmission of pathogens to native species has been highlighted as one of the most important impacts of biological invasions. In this study, we evaluated the presence of psittacine beak and feather disease virus (BFDV) and other circoviruses in native bird species cohabiting with invasive populations of wild rose-ringed (Psittacula krameri) an...
Population changes of invasive species can go unnoticed long before population explosions, so long-term monitoring programs are needed to assess changes in population size. Although invasive populations of rose-ringed (Psittacula krameri) and monk parakeets (Myiopsitta monachus) are present worldwide, their current status and dynamics are mostly po...
Over millennia, human intervention has transformed European habitats mainly through extensive livestock grazing. “Dehesas/Montados” are an Iberian savannah-like ecosystem dominated by oak-trees, bushes and grass species that are subject to agricultural and extensive livestock uses. They are a good example of how large-scale, low intensive transform...
Bird populations associated with agricultural ecosystems have declined markedly in Europe during the last quarter of the 20th century due to land-use intensification. This has meant that some very common species, in some cases even species considered as pests, are now threatened or subject to management programs to ensure their conservation. Consid...
The global pet trade is a major pathway for the introduction of invasive alien species. The composition of species selected for transport is driven by market demands, which may be influenced by a combination of both historical and cultural factors. We compared Eastern (Taiwan) and Western (Australia and the Iberian Peninsula) bird markets to explor...
Scientific and grey literature on invasive alien species (IAS) is conditioned by social, economic and political priorities, editorial preferences and species and ecosystem characteristics. This leads to knowledge gaps and mismatches between scientific research interests and management needs. We reviewed the literature on IAS management in Spain fou...
Certain traits of recipient environments, such as the availability of limiting resources, strongly determine the establishment success and spread of non-native species. These limitations may be overcome through behavioral plasticity, allowing them to exploit alternative resources. Here, we show how a secondary cavity nester bird, the rose-ringed pa...
While most of the knowledge on invasive species focuses on their impacts, little is known about their potential positive effects on other species. Invasive ecosystem engineers can disrupt recipient environments; however, they may also facilitate access to novel resources for native species. The monk parakeet (Myiopsitta monachus) is a worldwide inv...
Parrots stand out among birds because of their poor conservation status and the lack of available information on their population sizes and trends. Estimating parrot abundance is complicated by the high mobility, gregariousness, patchy distributions, and rarity of many species. Roadside car surveys can be useful to cover large areas and increase th...
Understanding of ecosystem structure and functioning requires detailed knowledge about plant–animal interactions, especially when keystone species are involved. The recent consideration of parrots as legitimate seed dispersers has widened the range of mechanisms influencing the life cycle of many plant species. We examined the interactions between...
Plant–animal interactions are key to sustaining whole communities and ecosystem function. However, their complexity may limit our understanding of the underlying mechanisms and the species involved. The ecological effects of epizoochory remain little known compared to other seed dispersal mechanisms given the few vectors identified. In addition, ep...
Falconry may constitute a source of exotic species through the escape into the wild of individuals kept in captivity. The introduction of top predators can have important ecological consequences for the recipient community, including genetic pollution through reproduction between falconry hybrids and wild raptors. Here we assessed the introduction...
Introduced organisms have to overcome several obstacles, including the scarcity of conspecific mates before becoming successfully established. We recorded interspecific mating in non‐native areas (Spain) that involved Orange‐winged Amazons Amazona amazonica with three non‐congeneric parrot species: Scaly‐headed Parrot Pionus maximiliani, Rose‐ringe...
We present a dataset that assembles occurrence records of alien tetrapods (amphibians, reptiles, birds and mammals) in the Iberian Peninsula, a coherent biogeographically unit where introductions of alien species have occurred for millennia. These data have important potential applications for ecological research and management, including the asses...
In some vertebrate species, family units are typically formed when sexually mature individuals delay dispersal and independent breeding to remain as subordinates in a breeding group. This behaviour has been intensively studied in gregarious species but has also been described in non-social species where ecological and evolutionary drivers are less...
Biological invasion is a global problem with large negative impacts on ecosystems and human societies. When a species is introduced, individuals will first have to pass through the invasion stages of uptake and transport, before actual introduction in a non‐native range. Selection is predicted to act during these earliest stages of biological invas...
Reducing greenhouse gas emissions is a global priority. To meet this goal, the Spanish government is planning 89 GW of wind and solar photovoltaic energy in the draft of the National Integrated Energy and Climate Plan (PNIEC) for 2021–2030 (1). Despite the Spanish government's efforts to prevent a speculative bubble in the secondary market, there a...
Protected areas are central to the conservation of biodiversity across the globe. However, their performance, especially in relation to highly mobile species, is largely dependent on the socio-ecological characteristics of the landscape that surrounds them. Here, we assess the patterns of avian scavenger distribution, including both obligate (i.e.,...
Illegal wildlife trade, which mostly focuses on high-demand species, constitutes a major threat to biodiversity. However, whether poaching is an opportunistic crime within high-demand taxa such as parrots (i.e., harvesting proportional to species availability in the wild), or is selectively focused on particular, more desirable species, is still un...
Owls (Strigiformes) evolved specific adaptations to their nocturnal predatory lifestyle, such as asymmetrical ears, a facial disc, and a feather structure allowing silent flight. Owls also share some traits with diurnal raptors and other nocturnal birds, such as cryptic plumage patterns, reversed sexual size dimorphism and acute vision and hearing....
The hypothalamus–pituitary–adrenal/interrenal (HPA) axis of vertebrates integrates external information and orches
trates responses to cope with energy-demanding and stressful events through changes in circulating glucocorticoid levels.
Urbanization exposes animals to a wide variety of ever-changing stimuli caused by human activities that may affec...
Background:
Non-native species are often introduced in cities, where they take advantage of microclimatic conditions, resources provided by humans, and competitor/predator release to establish and proliferate. However, native communities in the surrounding rural or natural areas usually halt their spread through biotic resistance, mainly via top-d...
The psittacine beak and feather disease (PBFD) is a globally widespread infectious bird disease that mainly affects species within the Order Psittaciformes (parrots and allies). The disease is caused by an avian circovirus (the beak and feather disease virus, BFDV), which is highly infectious and can lead to severe consequences in wild and captive...
We assessed the relative importance of human activity and environmental suitability as drivers of compositional dissimilarity of alien birds for 65 of the most populous cities of the Iberian Peninsula. We examined how these drivers relate to Zeta diversity (f) for alien Passeriformes and Psittaciformes. We performed the analysis using multiple orde...
When a species colonizes an urban habitat, differences in the environment can create novel selection pressures. Successful colonization will further lead to demographic perturbations and genetic drift, which can interfere with selection. Here, we test for consistent urban selection signals in multiple populations of the burrowing owl (Athene cunicu...
