- Thyroid hormone influences muscle mechanics in carp (Cyprinus carpio) independently from SERCA activity
Summary: Thyroid hormone plays a key role in maintaining normal levels of skeletal muscle force production in carp, but this is not mediated via SERCA.
- Programming of the hypothalamic-pituitary–interrenal axis by maternal social status in zebrafish (Danio rerio)
Summary: Maternal social status influences development of the stress axis and programmed stress axis function during early development in zebrafish.
- A flavanoid component of chocolate quickly reverses an imposed memory deficit
Summary: A naturally occurring substance (flavanol epicatechin, contained in chocolate) can immediately reverse a behavioural state whose phenotype prevents learning and memory formation.
- Life history trade-offs imposed by dragline use in two money spiders
Summary: Single silk-related behaviours induce lifetime trade-offs and affect performance in two species of spider.
- Transient and permanent effects of suboptimal incubation temperatures on growth, metabolic rate, immune function and adrenocortical responses in zebra finches
Summary: A 1°C difference in incubation temperature reduces survival, temporarily elevates metabolic rates and adrenocortical responses, and permanently reduces body mass in zebra finches.
- Characterising multi-level effects of acute pressure exposure on a shallow-water invertebrate: insights into the kinetics and hierarchy of the stress response
Summary: Elevated hydrostatic pressure causes changes in gene expression, behaviour and respiration rate in a shallow-water shrimp at different time-scales during and after exposure, highlighting the need to assess more than a single aspect of the overall stress response (OSR) in future physiological studies.
- Preconditioning in the reef-building coral Pocillopora damicornis and the potential for trans-generational acclimatization in coral larvae under future climate change conditions
Highlighted Article: Preconditioning and trans-generational acclimatization may provide a buffer for reef-building corals against the stress of rapidly changing climate.
- Consequences of calcium decline on the embryogenesis and life history of Daphnia magna
Summary: Ambient calcium is declining in thousands of soft-water lake habitats. Daphnia females provision their offspring with calcium and through that incur a potential allocation trade-off.
- The environmentally tuned transcriptomes of Mytilus mussels
Summary: Abiotic factors, such as temperature and the tidal cycle, drive patterns of gene expression in Mytilus mussels that underlie whole-organism physiological states, which, in turn, influence biogeographic distributions.
- Considerations for the use of transcriptomics in identifying the ‘genes that matter’ for environmental adaptation
Summary: The ability of transcriptomics to identify genes that underlie environmental adaptation is explored in the context of recent systems-level experiments that provide new insights into the relationship between gene expression and fitness.
