Introduction
My main interests are in population and host-pathogen dynamics, sex allocation and sexual selection. I see current available tools to model data from marked and unmarked individuals as a passe-partout to address most of ecological questions I am interested in. I have gone somehow deeper into capture-recapture (multi-event), hierarchical (occupancy and N-mixture) and matrix-population models. R is my favourite working environment and I am quite familiar with E-SURGE and MARK for CR analyses.

Article
Full-text available
Dispersal is a life-history trait directly affecting population dynamics and species range shifts and thus playing a prominent role in the response to climate change. Nonetheless, the relationship between extreme climatic events and dispersal has received little attention in birds. Here we focused on climatic, demographic and individual factors aff...
Article
Full-text available
Host-pathogen epidemiological processes are often unclear due both to their complexity and over-simplistic approaches used to quantify them. We applied a multi-event capture-recapture procedure on two years of data from three rabbit populations to test hypotheses about the effects on survival of, and the dynamics of host immunity to, both myxoma vi...

Immigration and local recruitment play a central role in determining the growth rate of breeding populations. Unravelling these processes in newly-established populations is of great importance to increase our understanding of how species change their distributions in response to global change. We studied the biggest colony of glossy ibis (Plegadis...
Article
Full-text available
The polygyny threshold model predicts that a female chooses an already-mated male if the direct benefits of higher territorial quality compensate for the cost of mate sharing. The sexy son hypothesis (SSH) expands this framework from direct to indirect benefits assuming that polygynously-mated females give birth to sexy and subsequently polygynous...
Article
Full-text available
Mating system theory predicts that social polygyny—when one male forms pair bonds with two females—may evolve by female choice in species with biparental care. Females will accept a polygynous male if the benefit of mating with a male providing high quality genes or rearing resources outweighs the cost of sharing mate assistance in parental care. B...
Article
Full-text available
Ecogeographical rules, such as Bergmann's and Allen's rules, describe empirical observations of homeotherm morphology's latitudinal patterns. In warmer climates, Bergmann's rule predicts that populations within a species or closely related species have smaller body sizes, whereas Allen's rule predicts a greater proportion of limbs and appendages re...

La nueva revolución en inteligencia artificial, liderada por los modelos de aprendizaje profundo, promete ayudar en multitud de tareas complejas que realizan los humanos. El fototrampeo es una de las herramientas no invasivas más utilizadas para el seguimiento de las especies animales, especialmente para los mamíferos terrestres. Debido a la elevad...
Article
Background: Fast-spreading diseases affecting wildlife populations threaten biodiversity. Two caliciviruses, Lagovirus europaeus/GI.1 and Lagovirus europaeus/GI.2, caused rabbit haemorrhagic disease virus (RHDV) in wild rabbits. Despite having different characteristics, these variants spread quickly, posing a threat to wild rabbit populations. Me...
Article
Counting latrines is a standard method to estimate European wild rabbits (Oryctolagus cuniculus) abundance. This method plays an important role in endangered predators’ conservation programs in the Iberian Peninsula, especially in potential reintroduction areas for the Iberian lynx (Lynx pardinus). However, since the last half-century, rabbit popul...
Article
Full-text available
Accurate methods for age determination are critical to the knowledge of wildlife populations' age structure and, therefore, to their successful management. The reliability of age estimation may have profound economic and ecological consequences on the management of the European wild rabbits, Oryctolagus cuniculus, in its native and introduced range...
Article
Full-text available
Why females engage in social polygyny remains an unresolved question in species where the resources provided by males maximize female fitness. In these systems, the ability of males to access several females, as well as the willingness of females to mate with an already mated male, and the benefits of this choice, may be constrained by the socio-ec...
Chapter
Full-text available
The sexy son hypothesis provides a theoretical framework to explain the evolution of social polygyny by female choice (Weatherhead and Robertson 1979). In some circumstances, a female would benefit in long-term fitness (number of grand-offspring) by forming a pair with an already-mated male instead that with an unmated competitor. The advantage, th...
Book

This is the first issue of the publication of the IUCN SSC Stork, Ibis and Spoonbill Specialist Group. The first issue is a Special Issue dedicated to the ecology and conservation of the Glossy Ibis Plegadis falcinellus. This has the participation of 75 researchers from various countries around the globe, and is the first monograph of the Glossy Ib...
Article
Full-text available
The Glossy Ibis is among the most widespread bird species in the world. However, the Glossy Ibis erratic occurrence and distribution makes it a difficult species to study, and we know little about its dispersal and metapopulation dynamics. This study summarises previously-scattered and unpublished information by collating, in a single database, the...
Article
Full-text available
Numbers of Glossy Ibis recorded in Britain have increased dramatically since the mid-2000s, mirroring the increase in their breeding population in southwest Europe, especially in Doñana (south Spain). Despite the increasing number of records in Britain, there are still only small numbers of Glossy Ibis present in spring and, so far, only two nestin...

Article
Dozens of morphologically differentiated populations, subspecies and species of crossbills (genus Loxia) exist. It has been suggested that this divergence is due to variation in the conifer cones that each population specialises upon, requiring a specific beak size to efficiently separate the cone scales. If so, apparent survival should depend on b...
Article
Full-text available
We present data of morphometric measurements of a wood mouse Apodemus sylvaticus population collected in the Doñana National Park (SW Spain) in the periods between 1978-81 and 2006-07. These data have been extrapolated from specimens deposited in the Doñana Biological Station Collection. The data in this article support the information provided in...
Article
We describe the extremely rapid worldwide spread of the Lagovirus europaeus/GI.2/RHDV2/b (henceforth GI.2), the causative infectious agent of the so‐called “novel” rabbit haemorrhagic disease of the European rabbit (Oryctolagus cuniculus). We tracked down all novel confirmed detections of GI.2 between May 2010 and November 2018 by carrying out a tw...

According to our best model, polygynously-mated females had lower survival probability (p= 0.51) than monogamous ones (p= 0.59). In the case of males, we did not found survival costs in relation to their mating status (p Monogamous= Polygynous= 0.54).
Article
Thermoregulation, metabolism and life history of species are affected by body size and shape. Based on specimens of the wood mouse Apodemus sylvaticus that were collected at Doñana National Park in 1978–81 and 2006–07, we tested for changes between these periods in body mass, body size, and allometry. Furthermore, we used data from 1978–81, when mo...

Understanding the ecological, behavioral and evolutionary response of organisms to changing environments is of primary importance in a human-altered world. It is crucial to elucidate how human activities alter gene flow and what are the consequences for the genetic structure of a species. We studied two lineages of the Egyptian fruit bat (Rousettus...
Article
Full-text available
In this study, we analyze the changes occurred since 1978 in the community of small mammals of Doñana and the relationship with local climatic changes. Capture-mark-recapture methods were carried out for a total of 16 years, distributed over the last four decades. The results clearly reflect a significant loss of diversity and decline of the commun...
Article
Full-text available
Climate change affects distribution and persistence of species. However, forecasting species’ responses to these changes requires long-term data series that are often lacking in ecological studies. We used 15 years of small mammal trapping data collected between 1978 and 2015 in 3 areas at Doñana National Park (southwest Spain) to (i) describe chan...

Full-text available
Myxomatosis and rabbit hemorrhagic disease (RHD) are the major viral diseases that affect the wild European rabbit (Oryctolagus cuniculus). These diseases arrived in Europe within the last decades and have caused wild rabbit populations to decline dramatically. Both viruses are currently considered to be endemic in the Iberian Peninsula; periodic o...
Article
Vaccination campaigns against myxomatosis and rabbit haemorrhagic disease (RHD) are commonly used in translocation programs conducted for the purpose of recovering wild European rabbit populations in Iberian Mediterranean ecosystems. In most cases rabbits are vaccinated ‘blind’ (i.e. without assessing their prior immunological status) for economic...

The sex ratio is an important parameter affecting population demographics. We studied the causes and mechanisms of changes over time in the sex ratio of the glossy ibis in the main breeding colony in Doñana. As colony size increased from seven pairs in 1996 to 4000 in 2011, a worsening of conditions seems to have increased mortality of female chick...
Conference Paper
Full-text available
Settlement of new population is unequivocally due to immigration from source populations. However, from thereon the population dynamics is also affected by local demographic processes (fecundity, survival and recruitment). We used capture-recapture and matrix population models to investigate the causal process beyond local dynamics and assess the c...
Article
Full-text available
If parental allocation to each offspring sex has the same cost/benefit ratio, Fisher's hypothesis predicts a sex ratio biased towards the cheaper sex. However, in dimorphic birds there is little evidence for this, especially at hatching. We investigated the pre-fledgling 1) sex ratio, 2) body condition and 3) sex-differential mortality in a populat...
Thesis
Full-text available
One of the most important issue in Population Ecology is understanding how demographic parameters change in response to environmental conditions. The relevance of this topic is increasing because of the current and future scenarios of global change. As a result, the scientific community is giving special interest to the study of ecological processe...

The "Why": Wildlife monitoring is often based on outdated protocols. However, advances in technology have paved the way for optimizing data collection and profusing cutting-edge analytical methods. The "What": 1) to train an artificial intelligence algorithm to automatically classifying species from (the rapidly exorbitant amount of) camera-trap images, 2) to set an automatic fauna census system capable of detecting changes in abundance and biodiversity more efficiently and in real-time than ever before. The "How": We are a multidisciplinary team with expertise in population ecology and computer vision. We'll integrate AI (convolutional neural network) and statistical modelling (hierarchical models) to analyze camera-trap data. For now, our cameras are placed in one of the most important protected areas in Europe, the Parque Nacional de Doñana (South Spain).

The Glossy ibis (Plegadis falcinellus) is the only cosmopolitan species of the Threskiornithidae family (ibis and spoonbills) and one the most widely distributed bird species in the world. Nonetheless, this is also an understudied species and, albeit so widespread, no knowledge exists on the intraspecific phylogeography and very little is known about the (meta)populations dynamics. This research network aims to fill this gap. We aim to promote local and coordinated research by standardizing protocols of data collection, organizing data sharing, and, when feasible, supporting and advising new ringing and monitoring schemes.
