Hypercapnia-induced disruption of long-distance mate-detection and reduction of energy expenditure in a coastal keystone crustacean

Molecular basis of parental contributions to the behavioural tolerance of elevated pCO2in a coral reef fish

“…Recent studies show that increased pCO 2 levels can affect the growth, survivorship and physiology of some marine fishes [3][4][5][6][7]. Elevated CO 2 has also been shown to alter behaviours in a wide variety of fish [8][9][10] and invertebrates [11][12][13]. However, most experimental studies focus on short-term exposure to elevated pCO 2 and do not account for phenotypic variation that may enable populations to adapt over the time scale at which OA will occur [2,14].…”

Toward a Mechanistic Understanding of Marine Invertebrate Behavior at Elevated CO2

“…In addition to continuing to assess the impact of elevated CO 2 on the range of behaviors previously studied (above), a few new behaviors have also been investigated. For example, the first study assessing the effect of elevated CO 2 on marine invertebrate reproductive behavior was recently published (Borges et al, 2018). Exposure of male amphipods Gammarus locusta to elevated CO 2 (800 µatm pCO 2 ) for two generations disrupted the chemosensory detection of potential mates (Borges et al, 2018).…”

Exposure of male amphipods Gammarus locusta to elevated CO 2 (800 µatm pCO 2 ) for two generations disrupted the chemosensory detection of potential mates (Borges et al, 2018). A light/dark test on swimming crabs Portunus trituberculatus exposed to control (485 µatm pCO 2 ) or elevated (750 µatm and 1,500 µatm pCO 2 ) CO 2 was the first to assess the impact of elevated CO 2 on anxiety-like behavior in a marine invertebrate.…”

Contrasting responses to salinity and future ocean acidification in arctic populations of the amphipod Gammarus setosus

“…Elevated pCO2 also resulted in lower rates of whole-organism oxygen uptake rates in amphipods from all populations. Another gammarid amphipod Gammarus locusta showed a similar response at pCO2 levels of 800-900 µatm (Borges, 2018). Metabolic depression represents a short-term survival strategy to protect energy reserves under stressful conditions which is thought to be a characteristic of species more sensitive to elevated CO2, such as polar species (Kelley and Lunden, 2017).…”
