I am interested in behavioural ecology, bioenergetics and eco-evolutionary processes.

Understanding animal movement is essential to elucidate how animals interact, survive, and thrive in a changing world. Recent technological advances in data collection and management have transformed our understanding of animal “movement ecology” (the integrated study of organismal movement), creating a big-data discipline that benefits from rapid,...
The vulnerability of fish to fishing depends on a range of life-history (e.g. growth; reproduction), behavioural (e.g. boldness) and physiological (e.g. metabolic rates) traits which are usually correlated with reproductive success. Therefore, between-fish differences in catchability may be indirectly affecting the reproductive potential at the pop...
Recent advances in tracking systems have revolutionized our ability to study animal movement in the wild. In aquatic environments, high-resolution acoustic telemetry systems make it technically possible to simultaneously monitor large amounts of individuals at unprecedented spatial and temporal resolutions, providing a unique opportunity to study t...
That this camera‐based method is sparking debate regarding its applicability to specific‐species is a symptom of the complexity of wildlife assessment in light of the increasing, unprecedented amount of ecological‐data, this task requires strengthening links between theorists and empiricists to profit the new opportunities offered by the method.
Spatial behavioural types (SBTs) arise from between-individual differences in behavioural traits that foster spatial behavioural patterns that are consistent over time and ecological contexts. Fish stocks are regularly assessed using catch per unit effort (CPUE) as input data that may non-linearly co-vary with the underlying abundance (N) of the ex...
Technological advances in underwater video recording are opening novel opportunities for monitoring wild fish. However, extracting data from videos is often challenging. Nevertheless, it has been recently demonstrated that accurate and precise estimates of density for animals (whose normal activities are restricted to a bounded area or home range)...
Consistent between‐individual differences in movement are widely recognised across taxa. In addition, foraging plasticity at the within‐individual level suggests a behavioural dependency on the internal energy demand. Because behaviour co‐varies with fast‐slow life history (LH) strategies in an adaptive context, as theoretically predicted by the pa...
Scoring animal behavior is increasingly needed for better understanding ecological processes. For example, behavior shapes harvesting likelihood, thus management of harvested resources should improve after accounting for behavior-driven processes. Automatic video-recording at controlled arenas is the most widespread method for scoring behavior. How...
The selective properties of fishing that influence behavioural traits have recently gained interest. Recent acoustic tracking experiments have revealed between-individual differences in the circadian behavioural traits of marine free-living fish; these differences are consistent across time and ecological contexts and generate different chronotypes...
The measurement of animal density may take advantage of recent technological achievements in wildlife video recording. Fostering the theoretical links between the patterns depicted by cameras and absolute density is required to exploit this potential. 2.We explore the applicability of the Hutchinson-Waser's postulate (i.e., when animal density is s...
The use of stereo underwater video cameras for monitoring marine fish is spreading. We have developed a low-cost stereo video cameras for estimating fish length with high precision and accuracy, including small juveniles. Current applications of underwater video technique at the Fish Ecology Group at IMEDEA, www.fishecology.es.
Repeatable between-individual differences in the behavioural manifestation of underlying circadian rhythms determine chronotypes in humans and terrestrial animals. Here, we have repeatedly measured three circadian behaviours, awakening time, rest onset and rest duration, in the free-ranging pearly razorfish, Xyrithchys novacula, facilitated by acou...

I need as much data as possible.
I need to know what criteria or algorithms are used by this automatically detection option (in TreeRings-13.ojj).
What intensity and wavelength of light must we use in experimental conditions when working with fish?
We want to carry out a set of experiments to study behavioural responses of fish to several stimulus. We want to record their behaviour and movement during long periods of time (10-15 days). The size of the tank is of 2x5m. The camera will be installed over the tank and tracking will be automatic. And so we need an illuminated scenario without shadows.
We have been thinking to use led lights but we wonder what intensity, colour temperature and wavelength to use in order to avoid negative effects on fish's behaviour and fitness.
