Introduction
I am a behavioural ecologist interested in unraveling the causes and consequences of consistent individual differences in behaviour (also called personality). I believed that studying personality in wild systems can allow us to understand how fluctuating environmental conditions shape behaviour. One of my research goals is to use statistical methods of the animal personality field on big telemetry data. Most of my work is done on the juvenile lemon shark, on billfish and on northern pike.

Article
Full-text available
Personality differences are widespread throughout the animal kingdom and can have important ecological and evolutionary consequences. Despite a rapidly increasing body of literature, large (marine) vertebrates remain underrepresented in personality research. Given their unique life history traits (e.g. slow growth rate, slow reproduction rate, long...
Article
Full-text available
Personality traits (i.e. consistent individual differences in behaviour) often covary, forming behavioural syndromes. Such associations, if driven by an underlying proximate mechanism, could limit the independent evolution of each behaviour. In contrast, a behavioural syndrome may be the result of selection favouring the behavioural correlation und...

1. Consistent individual differences in behaviour (i.e. personality) can be explained in an evolutionary context if they are favoured by life history trade-offs as conceptualized in the pace-of-life syndrome (POLS) hypothesis. Theory predicts that faster-growing individuals suffer higher mortality and that this trade-off is mediated through explora...
Article
Billfishes are well-known for their distinctive elongated rostra, a.k.a. bills. The functional significance of billfish rostra has been frequently discussed and the recent discovery of an oil gland (glandula oleofera) at the base of the rostrum in swordfish, Xiphias gladius , has added an interesting facet to this discussion regarding the potential...

Full-text available
In recent years, the incorporation of lower levels of organization to the understanding of population ecology, has led to an increase in interest for animal personality and individual foraging specialization. Despite these topics investigating comparable phenomena, i.e. individual consistency in behavior and in food resource use respectively, they...
Article
Learning is a process that allows animals to develop adaptive behavioural responses to novel situations within an individual's lifetime. The simplest form of learning, habituation, acts a fundamental filter mechanism, which allows animals to ignore irrelevant recurring stimuli, thereby freeing up fitness-related resources, such as time and energy,...
Article
Abundances of large sharks are reported to have declined worldwide, and in response various levels of fisheries management and conservation efforts have been established. For example, Marine Protected Areas have been suggested as means to protect large expanses of ocean from fishing and other industrial activities (e.g., habitat destruction), and i...
Article
Recent comparative studies of billfishes (Istiophoridae and Xiphiidae) have provided evidence of differences in the form and function of the rostra (bill) among species. Here, we report the discovery of a new structure, lacuna rostralis, on the rostra of sailfish Istiophorus platypterus, which is absent on the rostra of swordfish Xiphias gladius, s...
Thesis
In behavioural ecology, interest in the study of animal personality (i.e. consistent individual differences in behaviour across time and/or context) has increased in the last two decades as it is believed to have important ecological and evolutionary consequences. These consequences are especially pronounced when a behaviour that is consistent cova...
Article
Our study assessed the influence of leader type (monofilament vs stainless steel cable) and gear strength (i.e., hook size and leader thickness) on species composition, catch rates, and size distribution of sharks captured in a fisheries independent longline survey near Bimini, The Bahamas. A total of 28 surveys were conducted, resulting in 50,400...

Article
Full-text available
Wildlife provisioning is popular, economically valuable, and a rapidly growing part of marine tourism, with great potential to benefit conservation. However, it remains controversial due to limited understanding of its implications on the behavior and ecology of target species. In this study, we modeled how various abiotic and biotic factors influe...
Article
Tourism-related feeding of wildlife can result in detrimental, human-induced changes to the spatial distribution, social behaviour and health of target species. The feeding of sharks as part of shark-viewing activities has become increasingly popular in recent years to ensure reliable and consistent encounters. A common limitation in determining ho...

Linking morphological differences in foraging adaptations to prey choice and feeding strategies has provided major evolutionary insights across taxa. Here, we combine behavioural and morphological approaches to explore and compare the role of the rostrum (bill) and micro-teeth in the feeding behaviour of sailfish (Istiophorus platypterus) and strip...
Chapter
Because of its impact on our understanding of evolution and ecology, animal personality has become an important area of research within behavioral ecology. Indeed, individual variation is no longer considered random noise but as a consistent phenomenon that impacts animal biology. However, research on animal personality and individual differences h...

Full-text available
This study considers novel areas rarely explored, focusing on the link between individual movement ecology in natural conditions and personality traits in juveniles of a top-predator species of elasmobranch. The main aim is to provide an individual-based perspective to better apprehend the relationship between an intrinsic decision-making mechanism...
Conference Paper
Full-text available
In recent years, information on animal behavioral traits and consistent individual differences within species and/or populations has been expanding; yet, several aspects, such as the influence of personality on wild behavior, have not been addressed. This study focuses on the influence of personality on the natural space utilization and movement me...

Question
Hi everyone,
I would like to compile a lot of data into a database for open access.
The data will be mostly csv files but also some videos and images.
I don't really know where to start: I have heard MySQL is a good platform which is compatible with R (which is my most comfortable coding platform). So that's the main option I'm looking into right now.
Has anyone made such a database ? Could I look at it to indentify important components ? What programs did you use ?
Thanks a lot!
