- Experimental evolution of response to anoxia in Drosophila melanogaster: recovery of locomotion following CO2 or N2 exposure
Highlighted Article: An inadvertent evolutionary selection for rapid recovery from CO2 exposure for nearly 40 years has resulted in fast and consistent locomotor recovery from anoxia in Drosophila melanogaster.
- Evidence that Rh proteins in the anal papillae of the freshwater mosquito Aedes aegypti are involved in the regulation of acid–base balance in elevated salt and ammonia environments
Summary: Rh proteins in the anal papillae of mosquito larvae are involved in regulating acid–base balance.
- O2 binding and CO2 sensitivity in haemoglobins of subterranean African mole rats
Summary: Haemoglobin–O2 binding properties of African mole rats reveal low specific CO2 sensitivities compared with humans that predictably safeguard O2 uptake and transport under hypoxic and hypercapnic conditions.
- Interactive effects of oxygen, carbon dioxide and flow on photosynthesis and respiration in the scleractinian coral Galaxea fascicularis
Summary: A multifactorial experiment reveals no effect of oxygen on coral photosynthesis and an increase in coral photosynthesis under high flow and a doubled concentration of dissolved carbon dioxide.
- The insect ovipositor as a volatile sensor within a closed microcosm
Highlighted Article: While antennae are usually considered the main volatile sensors in insects, we show that the ovipositor is also an efficient sensor for plant volatiles and carbon dioxide and performs olfaction.
- Metabolic recovery from drowning by insect pupae
Highlighted Article: Despite their status as terrestrial insects, pupae of Manduca sexta survived 5 days underwater and showed diverse and unusual patterns of CO2 emission during recovery.
- Ambient CO2, fish behaviour and altered GABAergic neurotransmission: exploring the mechanism of CO2-altered behaviour by taking a hypercapnia dweller down to low CO2 levels
Highlighted Article: Although high levels of CO2 have repeatedly been linked to behavioural disturbance in marine fish, reducing CO2 concentration alters behaviour in a hypercapnia-dwelling fish, suggesting that neural ion balance is fine-tuned to prevailing CO2 conditions.
- Flea fitness is reduced by high fractional concentrations of CO2 that simulate levels found in their hosts' burrows
Highlighted Article: Fleas living in high fractional concentrations of CO2 have reduced survival and reproduction.
- Interactive effects of seawater acidification and elevated temperature on biomineralization and amino acid metabolism in the mussel Mytilus edulis
Summary: The interactive effects of climate stressors on marine calcifiers highlight the negative effect of elevated temperature based on seawater acidification.
- High capacity for extracellular acid–base regulation in the air-breathing fish Pangasianodon hypophthalmus
Summary: Pangasius has a much higher capacity for extracellular acid–base regulation during exposure to hypercapnia compared with other air-breathing fishes.
