Introduction
My main line of research is Ecological Modeling with applications in very diverse fields such as Dendroecology, Landscape Ecology, Grassland Ecology, Bioacoustics, Marine Biology, etc. I have been a member of AEST (Spanish Association of Gifted and Talented) and MENSA. Therefore, I am very interested in the detection, training and integration of gifted students in academic institutions. I maintain a YouTube channel on these topics.

Article
Delphinus delphis Linnaeus 1758 is considered an endangered species in the Mediterranean. The species is resident in the Bay of Algeciras - Gibraltar (southern Spain; waters partially shared with Gibraltar, UK). This area is subject to strong anthropogenic pressure, but with an input of renewed waters in its central area. During three consecutive y...
Article
Songbirds are one of the groups most vulnerable to extreme heat events. Although several recent studies have assessed their physiological responses to heat, most of them have focused on arid-zone species solely. We investigated thermoregulatory responses to heat in eight small-sized songbirds occurring in the Mediterranean Basin, where heatwaves ar...

Since 2015, the invasive alga Rugulopteryx okamurae has explosively burst into the waters of the Strait of Gibraltar with serious repercussions on marine biodiversity, tourism and the fishing industry. Its elimination entails an enormous cost for the municipalities in the area and vermicomposting is proposed as a solution, but the anti-food seconda...

Article
(1) Background: Desertification is one of the most important environmental impacts around the world. In the semiarid grassland of North of Chile, overgrazing has deep effects on arid lands and consequently on its economy and social development. It is necessary to conduct very detailed studies to determine how the climate, the botanical composition...
Article
Water stress triggers acclimation responses and can damage plants, which varies by species and stress levels. Ongoing climate change is projected to result in longer and more intense water stress conditions leading to an alarming increase in drought-induced forest decline. The aim of this study was to evaluate the physiological responses of leaves...
Article
1) Background: The NDVI (Normalized Difference Vegetation Index) is a basic indicator of photosynthetic activity frequently employed in landscape and urban ecology. However, the high-resolution determination of NDVI requires an expensive multi-spectral digital camera. (2) Methods: In the present work, we are developing a general procedure that conv...
Article
Ecoacoustics explains how animal and human behavior are affected by environmental sounds. Many studies show the marked role that sound has on people's psychological health. Our world is more and more scarce in natural sounds that produce our well-being. In this sense, we explore what acoustic parameters are related to human comfort in cities. For t...

Chapter
The low number of fin whales (Balaenoptera physalus L.) from Mediterranean waters shows a very fragmented distribution. The presence of this species in the Catalan coast has been confirmed by different studies. A semivariogram analysis concludes that the maximum spatial variability is 15.86 km², much higher than in other areas along the world. In o...
Chapter
Sperm whale (Physeter macrocephalus L.) is one of the six common species from the Gibraltar Strait. This cetacean is threatened due to ship collisions in an area of high marine traffic. It is very urgent to understand the factors implicated in the distribution of this endangered species. In this paper, we show a combination of three methods of spat...
Chapter
Cetaceans are undoubtedly the most acoustically complex animal group that exists. Throughout their evolution they have developed their tremendous variability due to very different selective pressures in very diverse ecological niches. Formant analysis is a methodology based on extracting the frequencies that are correlated in temporal windows of sh...
Book
Cetaceans are one of the most unknown groups in the animal kingdom. Their study is very difficult due to their scarcity, their flighty behavior, and their enormous displacements. In addition, some species feed in very deep waters and only emerge to breathe, or they live in hard to reach areas. However, few animals create so much wonder. What child...
Chapter
Humpback whales show the greatest acoustic complexity of the animal kingdom. Their sound emissions present functionalities ranging from the calls of cohesion during the migration, the territorial calls of the males, the maternal-filial communication or the echolocation. Following the methodology of phonetic analysis using formants, we find three ac...
Chapter
Up to four species of resident cetaceans can be observed in the Strait of Gibraltar. Between them we can find the common (Delphinus delphis) and the striped dolphin (Stenella coeruleoalba). Data from both species have been collected during twelve years from opportunistic platforms of whale watching, obtaining 436 records of common and 1,138 records...
Chapter
The methodological approach of the blue economy allows us to determine the effect of certain animal groups on monetary returns on a global scale. In this sense, cetaceans have not been enough studied. However, there is important evidences on its positive impact on the human economy. Their faeces have an important fertilizing effect, as they capture...
Chapter
Cetaceans are highly complex acoustically showing a great variety of type of vocalizations and frequency ranges. Traditionally, these emissions have been analyzed by spectrograms because they allow a quick visual understanding of the characteristics of each species. In the present work, we show an analytic methodology based on qualitative character...
Article
The absence of precise dates in Extremadura's Renaissance heritage can generate ambiguities that hinder the cultural interpretation of regional history. The analysis of the duration of the art styles, the date of construction of buildings and artefacts or the exact determination of restoration periods are severely affected by the absence of specifi...

La estabilidad es un concepto clave en el análisis de muchos procesos ecológicos. En su forma más simplificada es el inverso del coeficiente de variación, es decir, el cociente entre la media y la desviación típica de un parámetro dado. Dicho de otro modo, mide en que medida un proceso se mantiene sin oscilaciones significativas que comprometan su...
