Subject collection: Ecophysiology: responses to environmental stressors and change
- Ocean acidification affects calcareous tube growth in adults and reared offspring of serpulid polychaetes
Summary: Investigation of calcified tube growth of Serpulidae under low-pH conditions indicates that ocean acidification will negatively affect the initiation and persistence of both biofouling and epiphytic polychaete tube worms.
- ATP-induced reversed thermal sensitivity of O2 binding in both major haemoglobin polymorphs of the non-endothermic Atlantic cod, Gadus morhua
Summary: Phenotypic plasticity allows both major haemoglobin polymorphs of non-endothermic Atlantic cod to show ATP-induced reversed thermal sensitivity of oxygen binding at their warming southern distribution limit in the North East Atlantic.
- Body condition impacts blood and muscle oxygen storage capacity of free-living beluga whales (Delphinapterus leucas)
Summary: The relationship between body condition and blood and muscle O2 stores in beluga whales may represent a vicious cycle, in which decreases in condition impair foraging ability, leading to further reductions in condition.
- 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.
- Effects of temperature and salinity on body fluid dynamics and metabolism in the estuarine diamondback terrapin (Malaclemys terrapin)
Summary: Estuarine diamondback terrapins maintain osmotic balance under variable salinity conditions by using energetically efficient behavioral adjustments and water conservation strategies.
- Vision is highly sensitive to oxygen availability in marine invertebrate larvae
Editors' Choice: Reduced oxygen availability decreases retinal sensitivity and temporal resolution in marine invertebrate larvae, which may impact visual behaviors crucial to survival and increase vulnerability of species to ocean oxygen loss.
- Ocean warming combined with lower omega-3 nutritional availability impairs the cardio-respiratory function of a marine fish
Summary: The synergistic effects of rising sea temperature and reduced omega-3 food content impair cardiac function of a key ecological fish species, at individual, cellular and individual levels.
- Morph- and sex-specific effects of challenging conditions on maintenance parameters in the Gouldian finch
Highlighted Article: Gouldian finches exhibit physiological divergence between individuals of different morphs and between reproductive partners under energetically demanding conditions (heatwave, moult or reproduction).
- Dissecting cause from consequence: a systematic approach to thermal limits
Summary: Integrative models composed of multiple cause-and-effect hypotheses may rapidly uncover the mechanisms setting organismal thermal limits.
- Measurement and modelling of primary sex ratios for species with temperature-dependent sex determination
Summary: A new model for estimating sex ratios from temperature traces for species with temperature-dependent sex determination.
