High variability in aggression and habituation to the mirror assay in ornamenta...
Silva, Melina Coelho da; Canário, Adelino V. M.; Hubbard, Peter C.; Cardoso, Sara D.; Gonçalves, David; da Silveira Gonçalves, David MiguelUnderstanding consistent inter-individual variability in animal behaviour, known as personality traits, is essential for exploring the mechanisms and evolutionary consequences of behavioural diversity. Aggressive behaviour influences survival, resource acquisition, and reproduction, so clarifying individual differences can enhance our understanding of ecological dynamics and improve experimental design accuracy...
Differential effects of food restriction and warming in the two-spotted goby: I...
Lopes, Ana F.; Murdoch, Robyn; Cardoso, Sara D.; Madeira, Carolina; Costa, Pedro M.; Félix, Ana Sofia; Oliveira, Rui Filipe; Bandarra, NarcisaClimate change is a growing threat to marine organisms and ecosystems, and it is already modifying ocean properties by, for example, increasing temperature and decreasing pH. Increasing water temperature may also lead to an impairment of primary productivity and an overall depletion of available zooplankton. Understanding how the crossover between warming and zooplankton availability impacts fish populations ha...
Temporal variation in brain transcriptome is associated with the expression of ...
Cardoso, Sara D.; Gonçalves, David; Goesmann, Alexander; Canário, Adelino V.M.; Oliveira, Rui F.Distinct patterns of gene expression often underlie intra- and inter-sexual differences, and the study of this set of co-regulated genes is essential to understand the emergence of complex behavioural phenotypes. Here, we describe the development of a de novo transcriptome and brain gene expression profiles of wild-caught peacock blenny, Salaria pavo, an intertidal fish with sex-role reversal in courtship behav...

Social Plasticity Relies on Different Neuroplasticity Mechanisms across the Bra...
Teles, Magda C.; Cardoso, Sara D.; Oliveira, Rui F.Social living animals need to adjust the expression of their behavior to their status within the group and to changes in social context and this ability (social plasticity) has an impact on their Darwinian fitness. At the proximate level social plasticity must rely on neuroplasticity in the brain social decision-making network (SDMN) that underlies the expression of social behavior, such that the same neural ci...
Social network predicts loss of fertilizations in nesting males of a fish with ...
Cardoso, Sara D.; Faustino, Ana Isabel Soares; Costa, Silvia S.; Valério, Fábio; Gonçalves, David; Oliveira, Rui FilipeAlternative reproductive tactics (ARTs) evolve when there is strong intra-sexual competition between conspecifics for access to mates. Typically, larger Bbourgeois^ males reproduce by securing the access to reproductive resources while smaller Bparasitic^ males reproduce by stealing fertilizations from larger males. A number of factors can influence the reproductive success of each tactic, including intrinsic (...
Neurogenomic mechanisms of social plasticity
Cardoso, Sara D.; Teles, Magda; Oliveira, Rui FilipeGroup-living animals must adjust the expression of their social behaviour to changes in their social environment and to transitions between life-history stages, and this social plasticity can be seen as an adaptive trait that can be under positive selection when changes in the environment outpace the rate of genetic evolutionary change. Here, we propose a conceptual framework for understanding the neuromolecula...
