Article
Simone Vincenzi, Auteur ; Dušan Jesenšek, Auteur ; Alain Jean Crivelli, AuteurThe differences in life-history traits and processes between organisms living in the same or different populations contribute to their ecological and evolutionary dynamics. We developed mixed-effect model formulations of the popular size-at-age [...]
Article
Camille Musseau, Auteur ; Simone Vincenzi, Auteur ; Frédéric Santoul, Auteur ; Stéphanie Boulêtreau, Auteur ; Dušan Jesenšek, Auteur ; Alain Jean Crivelli, AuteurIntraspecific trait variability (ITV) maintains functional diversity in populations and communities, and plays a crucial role in ecological and evolutionary processes such as trophic cascades or speciation. Furthermore, functional variation with[...]
Article
Simone Vincenzi, Auteur ; Alain Jean Crivelli, Auteur ; Dušan Jesenšek, Auteur ; Ellen Campbell, Auteur ; John C. Garza, AuteurInvasions occurring in natural environments provide the opportunity to study how vital rates change and life histories evolve in the presence of a competing species. In this work, we estimate differences in reproductive traits, individual growth[...]
Article
Simone Vincenzi, Auteur ; Dušan Jesenšek, Auteur ; John C. Garza, Auteur ; Alain Jean Crivelli, AuteurThe hypothesis that the effects of heterozygosity vary with environmental conditions was tested using six populations of marble trout Salmo marmoratus from western Slovenia as a model system. The hypotheses tested were: stronger effects of heter[...]
Article
Simone Vincenzi, Auteur ; Dušan Jesenšek, Auteur ; Alain Jean Crivelli, AuteurWe develop a general framework that combines long-term tag–recapture data and powerful statistical and modelling techniques to investigate how population, environmental and climate factors determine variation in vital rates and population dynami[...]
Article
Simone Vincenzi, Auteur ; Marc Mangel, Auteur ; Dušan Jesenšek, Auteur ; John Carlos Garza, Auteur ; Alain Jean Crivelli, AuteurClimate change is predicted to increase the frequency and intensity of extreme climate events. Tests on empirical data of theory-based predictions on the consequences of extreme climate events are thus necessary to understand the adaptive potent[...]
Article
Simone Vincenzi, Auteur ; Marc Mangel, Auteur ; Dusˇan Jesensˇek, Auteur ; John C. Garza, Auteur ; Alain Jean Crivelli, AuteurUnderstanding the causes of within- and among-population differences in vital rates, life histories, and population dynamics is a central topic in ecology. To understand how within- and among-population variation emerges, we need long-term studi[...]
Article
Simone Vincenzi, Auteur ; Alain Jean Crivelli, Auteur ; Stephan Munch, Auteur ; Hans J. Skaug, Auteur ; Marc Mangel, AuteurBetter understanding of variation in growth will always be an important problem in ecology. Individual variation in growth can arise from a variety of processes; for example, individuals within a population vary in their intrinsic metabolic ra[...]
Article
Camille Musseau, Auteur ; Simone Vincenzi, Auteur ; Dušan Jesenšek, Auteur ; Isabel Cantera, Auteur ; Stéphanie Boulêtreau, Auteur ; Frédéric Santoul, Auteur ; Alain Jean Crivelli, AuteurDans Ecosphere (6 - 12 )Dietary plasticity of populations can be associated to ontogenetic diet preferences and depends on the size-structure of populations. Dietary niche characterizes the functional role of organisms in a food web, as it reflects both resources' dive[...]
Article
Simone Vincenzi, Auteur ; Dušan Jesenšek, Auteur ; Alain Jean Crivelli, AuteurDespite the widespread recognition of the importance of monitoring, only a few studies have explored how estimates of vital rates and predictions of population dynamics change with additional data collected along the monitoring program. We inves[...]
Article
Simone Vincenzi, Auteur ; Alain Jean Crivelli, Auteur ; Dušan Jesenšek, Auteur ; Jean-Francois Rubin, Auteur ; Gilles Poizat, Auteur ; Giulio A. De Leo, AuteurWhile several population viability analyses (PVAs) have been performed on anadromous salmonids, less attention has been given to stream-living salmonids. in this work, we explore the role of PVA as a tool in the recovery of threatened stream-liv[...]
