- Synergetic effects of immune challenge and stress depress cortisol, inflammatory response and antioxidant activity in fish-eating Myotis
Summary: Analysis of the cortisol–oxidative stress relationship, and the effect of simultaneous exposure to prolonged stress and an immune challenge in the insular bat Myotis vivesi.
- Prolonged exposure to stressors suppresses exploratory behavior in zebrafish larvae
Summary: Prolonged exposure to noxious chemical and electric shock stressors produces characteristic changes in behavior and neural activity in zebrafish larvae.
- Social hierarchy reveals thermoregulatory trade-offs in response to repeated stressors
Summary: Stress-induced changes in surface temperature are mediated by social hierarchies and, as such, reveal trade-offs between thermoregulation and stress responsiveness in a temperate endotherm.
- Aquatic and terrestrial takeoffs require different hindlimb kinematics and muscle function in mallard ducks
Summary: Mallard ducks use environment-specific locomotor patterns (i.e. kinematics and lateral gastrocnemius muscle strain patterns) during takeoff from water versus land.
- Acute and chronic stress prevents responses to pain in zebrafish: evidence for stress-induced analgesia
Summary: Exposure of zebrafish to acute or chronic stress prior to fin clipping prevents behavioural changes normally seen after fin clip; naloxone treatment prevented this effect, demonstrating stress-induced analgesia.
- Octopamine mobilizes lipids from honey bee (Apis mellifera) hypopharyngeal glands
Summary: Octopamine induces the release of lipids from tissue stores in many insects and can also induce lipid mobilization from honey bee hypopharyngeal glands.
- Experimental manipulation of perceived predation risk and cortisol generates contrasting trait trajectories in plastic crucian carp
Summary: The effect of perceived predation risk and cortisol manipulation on plastic anti-predator traits in crucian carp.
- Rapid cold hardening: ecological relevance, physiological mechanisms and new perspectives
Summary: Rapid cold hardening allows ectotherms to quickly enhance their cold tolerance. Here, we review the ecological relevance, underlying mechanisms and future research directions for this important process.
- Short-term dehydration influences baseline but not stress-induced corticosterone levels in the house sparrow (Passer domesticus)
Summary: Elevated baseline corticosterone levels induced by water restriction may have critical consequences on several major life-history traits such as energy budget, mobility and potential responses to predators.
- Investigating the relationship between corticosterone and glucose in a reptile
Summary: In situ and manipulation experiments in wandering gartersnakes show plasma glucose is elevated during acute stress, but corticosterone concentrations are not tightly correlated with glucose concentrations.
