developmental plasticity
- Life-long exposure to hypoxia affects metabolism and respiratory physiology across life stages in high-altitude deer mice (Peromyscus maniculatus)
Summary: Life-long exposure to hypoxia alters hypoxic metabolic depression throughout life with age-specific effects on breathing.
- Both maternal and embryonic exposure to mild hypoxia influence embryonic development of the intertidal gastropod Littorina littorea
Summary: Maternal and embryonic exposure to mild hypoxia influence timings of developmental events, whereas aspects of embryo morphology and overall development time were influenced only by embryonic exposure to mild hypoxia.
- nkx3.2 mutant zebrafish accommodate jaw joint loss through a phenocopy of the head shapes of Paleozoic jawless fish
Summary: Jaw dysfunctions are generally deleterious, but zebrafish mutants lacking jaw joints survive and dramatically alter their skull shape and feeding, developing superficial resemblance to distantly related jawless vertebrates.
- Consequences of rapid development owing to cohort splitting: just how costly is it to hurry?
Summary: We provide a robust empirical contribution to the understanding of individual-level consequences of developmental plasticity leading to cohort splitting, and highlight its importance in shaping key life history traits.
- Maternal glucocorticoids promote offspring growth without inducing oxidative stress or shortening telomeres in wild red squirrels
Summary: Experimental increases in glucocorticoids in breeding female North American red squirrels affects offspring postnatal growth but not levels of oxidative damage and antioxidants or telomere lengths.
- Developmental effects of heatwave conditions on the early life stages of a coral reef fish
Summary: Juvenile damselfish exposed in early life to a sufficient duration of heatwave conditions are smaller in size but have better predator-escape performance.
- Reproductive fitness of Drosophila is maximised by optimal developmental temperature
Summary: Developmental acclimation does not necessarily enhance reproductive fitness in Drosophila melanogaster; instead, the highest fitness is achieved by development at an optimal temperature.
- Developmental phenotypic plasticity helps bridge stochastic weather events associated with climate change
Summary: Unpredictable environmental phenomena associated with climate change can be challenging to developing organisms, but developmental phenotypic plasticity may be key to their survival.
- Metabolome dynamics of diapause in the butterfly Pieris napi: distinguishing maintenance, termination and post-diapause phases
Highlighted Article: Diapause in a temperate butterfly is associated with a highly dynamic metabolome, and its termination, once initiated by cold, is associated with temperature-independent changes in profiles of several key metabolites.
- Hotter nests produce hatchling lizards with lower thermal tolerance
Highlighted Article: Gecko embryos that experience high temperatures during incubation produce hatchlings with lower thermal tolerance, suggesting that lizards may have limited capacity to adapt to higher nest temperatures.
