Social zebrafish: Danio rerio as an emerging model in social neuroendocrinology
Kareklas, Kyriacos; Teles, Magda C; Nunes, Ana Rita; F. Oliveira, RuiThe fitness benefits of social life depend on the ability of animals to affiliate with others and form groups, on dominance hierarchies within groups that determine resource distribution, and on cognitive capacities for recognition, learning and information transfer. The evolution of these phenotypes is coupled with that of neuroendocrine mechanisms, but the causal link between the two remains underexplored. Gr...
Short telomeres drive pessimistic judgement bias in zebrafish.
Espigares, F.; Abad-Tortosa, D.; Varela, S. A. M.; Ferreira, M. G.; F. Oliveira, RuiThe role of telomerase reverse transcriptase has been widely investigated in the contexts of ageing and age-related diseases. Interestingly, decreased telomerase activities (and accelerated telomere shortening) have also been reported in patients with emotion-related disorders, opening the possibility for subjective appraisal of stressful stimuli playing a key role in stress-driven telomere shortening. In fact,...
