- 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.
- Can the behaviour of threespine stickleback parasitized with Schistocephalus solidus be replicated by manipulating host physiology?
Summary: Hypotheses regarding causes of the behavioural modifications in threespine stickleback parasitized with the flatworm Schistocephalus solidus are tested by analyzing behaviour changes induced by experimental manipulations.
- Morphine addiction in ants: a new model for self-administration and neurochemical analysis
Highlighted Article: Our model, ants, provides an opportunity to study addiction in a highly social species and establishes ants as the first linked behavioral and neurochemical model of invertebrate opioid addiction.
- Aquatic surface respiration and swimming behaviour in adult and developing zebrafish exposed to hypoxia
Summary: Aquatic surface respiration in fish is a behavioural response that is reliant upon input from peripheral oxygen chemoreceptors.
