- Climate change and invasive species: a physiological performance comparison of invasive and endemic bees in Fiji
Highlighted Article: Invasive bees in Fiji have greater thermal tolerance and are more desiccation resistant than the only native bee in lowland Fiji. Plant–pollinator relationships might shift with continued climate warming.
- Drivers of plasticity in freeze tolerance in the intertidal mussel Mytilus trossulus
Summary: Plasticity in freeze tolerance in an intertidal mussel is correlated with an accumulation of osmolytes, supporting the hypothesis that osmolytes are important cryoprotectants in intertidal invertebrates.
- Thermal acclimation offsets the negative effects of nitrate on aerobic scope and performance
Summary: Nitrate exposure increases the susceptibility of fish to acute changes in temperature by lowering aerobic scope and performance, but thermal phenotypic plasticity can override these potentially detrimental effects.
- Flight activity and glycogen depletion on a low-carbohydrate diet
Summary: On a low-carbohydrate diet, flies experience a reduction in glycogen stores yet increase flight activity without changing rates of glycogen depletion.
- Acclimatization in the physiological performance of an introduced ectotherm
Summary: Introduced species use acclimatization to maintain high performance year round; therefore, phenotypic flexibility likely shapes the fundamental niche of both introduced and native species.
- 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.
- Anthropogenic noise and the bioacoustics of terrestrial invertebrates
Summary: We review the current literature on invertebrate bioacoustics and characteristics of anthropogenic noise to suggest a framework for understanding the potential impact of anthropogenic noise on terrestrial invertebrates.
- Comparing thermal performance curves across traits: how consistent are they?
Summary: Examination of the extent to which thermal performance curves differ across traits and the timing of the temperature exposure, with regard to predictions of species responses to climate change.
- Within-individual behavioural variability and division of labour in social insects
Summary: This Commentary discusses the sources of within-individual behavioural variability in social insects and considers the relationship between colony size and behavioural flexibility.
