...Kirsty J. MacLeod; Sinead English; Suvi K. Ruuskanen; Barbara Taborsky ABSTRACT The social environment is one of the primary sources of challenging stimuli that can induce a stress response in animals. It comprises both short-term and stable interactions among conspecifics (including unrelated...

We found that all cups stick better on stiffer substrates and worse on more compliant ones, as indicated by peak stress values. On compliant substrates, surface roughness had...

Furthermore, peak stresses and steady-state stresses increased non-linearly with fiber length ( P <0.0001). We conclude that active...

.... However, in freshly collected outbred snails, the same heat stressor blocks LTM formation in ‘smart’ cognitive phenotype but not in average cognitive phenotype strains. Here, we hypothesize that (1) preventing the stress associated with the heat stressor before training allows LTM to form in the smart...

... of thermoregulation can also be immense, yet our understanding of whether a stress response is sufficient to induce changes in thermoregulatory investment is limited. Using the black-capped chickadee as a model species, we tested a hypothesis that stress-induced changes in surface temperature ( T s ), a well...

.... In principle, we can reduce stress-induced declines in colony health by either removing the stressor or increasing the bees' tolerance to the stressor. This latter option requires a better understanding than we currently have of how honey bees respond to stress. Here, we investigated how octopamine, a stress...
