- Differential construction response to humidity by related species of mound-building termites
Summary: Two mound-building termite species occupying the same locale are morphologically and behaviourally similar but create different macro-scale structures, and demonstrate this differential building behaviour under low-humidity conditions.
- Implications of the Sap47 null mutation for synapsin phosphorylation, longevity, climbing proficiency and behavioural plasticity in adult Drosophila
Summary: Sap47 belongs to the conserved, functionally enigmatic Syap1/Sap47 synaptic protein family. Behavioural analysis, longevity studies, phospho-specific immunohistology, electrophysiology and mass spectrometry characterize the function of Sap47 in Drosophila.
- Effects of natural wing damage on flight performance in Morpho butterflies: what can it tell us about wing shape evolution?
Summary: Investigation of natural wing damage in Morpho butterflies shows that flight performance depends on damage location, indicating that different wing parts play different roles during flight.
- Salmonid gene expression biomarkers indicative of physiological responses to changes in salinity and temperature, but not dissolved oxygen
Summary: Gene expression biomarkers associated with salinity stress and thermal stress, but not hypoxic stress, exist in salmon gill tissue. Biomarkers were also associated with mortality.
- Resource profitability, but not caffeine, affects individual and collective foraging in the stingless bee Plebeia droryana
Highlighted Article: Caffeine does not cause Plebeia droryana to increase foraging frequency, recruitment and persistence; instead, higher sugar concentrations cause bees to increase foraging effort.
- Food deprivation reduces social interest in the European sea bass Dicentrarchus labrax
Summary: Effects of food deprivation on three behavioural traits – risk taking, exploratory activity and solitariness – as well as the relationships between them, in juvenile sea bass.
- Do naked mole rats accumulate a metabolic acidosis or an oxygen debt in severe hypoxia?
Summary: Naked mole rats enter into a coma-like state upon reoxygenation following severe hypoxia but do not pay off an oxygen debt.
- Social stress increases plasma cortisol and reduces forebrain cell proliferation in subordinate male zebrafish (Danio rerio)
Summary: Elevated cortisol reduces cell proliferation in the telencephalon of socially subordinate male, but not female, zebrafish.
- Hunting in archerfish – an ecological perspective on a remarkable combination of skills
Summary: The fascinating hunting behaviour of archerfish is discussed from an ecological perspective.
- Glyphosate impairs learning in Aedes aegypti mosquito larvae at field-realistic doses
Summary: Although the herbicide glyphosate supposedly affects only plants, it impaired learning ability in mosquito larvae in a dose-dependent manner.
