- Serotonergic control in initiating defensive responses to unexpected tactile stimuli in the trap-jaw ant Odontomachus kuroiwae
Highlighted Article: The serotonergic system in the nervous system contributes to the initiation of defensive turn responses to unexpected tactile stimuli in the trap-jaw ant.
- A mutation in monoamine oxidase (MAO) affects the evolution of stress behavior in the blind cavefish Astyanax mexicanus
Summary: A mutation in the serotonin neurotransmitter pathway that lowers basal stress levels but increases the amplitude of stress response can spread in cavefish populations living in singular environments.
- The stalk-eyed fly as a model for aggression – is there a conserved role for 5-HT between vertebrates and invertebrates?
Summary: We propose that the role of 5-HT in modulating invertebrate aggression is more nuanced than previously appreciated; there is evidence for distinct roles of 5-HT receptor subtypes in stalk-eyed flies, similar to the situation in vertebrates.
- Effects of monoamine manipulations on the personality and gene expression of three-spined sticklebacks
Summary: Serotonergic and dopaminergic gene expression causally explains aspects of stickleback personality. Human pharmaceuticals make sticklebacks bolder, demonstrating consequences of human medical waste for wildlife.
- Anti-diuretic action of a CAPA neuropeptide against a subset of diuretic hormones in the disease vector Aedes aegypti
Summary: AedaeCAPA-1 inhibits select diuretic factors involved in Malpighian tubule fluid and ion secretion in Aedes aegypti, probably via the second messenger cGMP.
- The stomatogastric nervous system of the medicinal leech: its anatomy, physiology and associated aminergic neurons
Summary: Blood feeding is a signature activity of the medicinal leech. The presence and characteristics of the stomatogastric nervous system, vital for feeding, are reported here for the first time.
- SERT gene polymorphisms are associated with risk-taking behaviour and breeding parameters in wild great tits
Summary: Genetic variability of the serotonin transporter gene plays an important role in shaping individual decision-making that affects fitness in a wild population of great tits.
- The gastric caecum of larval Aedes aegypti: stimulation of epithelial ion transport by 5-hydroxytryptamine and cAMP
Summary: Transport of H+, Na+ and K+ across the gastric caecum of larval mosquitoes is stimulated by serotonin acting through the intracellular messenger cAMP.
- Myogenic activity and serotonergic inhibition in the chromatophore network of the squid Dosidicus gigas (family Ommastrephidae) and Doryteuthis opalescens (family Loliginidae)
Summary: A comparative physiological and immunohistochemical examination of coordinated activity among squid chromatophores in the absence of neural control and serotonin inhibition.
- How do individuals cope with stress? Behavioural, physiological and neuronal differences between proactive and reactive coping styles in fish
Summary: Fish characterised with opposite coping styles show telencephalic region-specific differences associated with their behavioural responses to stimuli.
