The Antarctic-Magellan connection: Macrobenthos ecology on the shelf and upper slope, a progress report (2005, background): “These questions are dealt with in the review by Pörtner et al. (2005) and recent work by Peck (2001) and Clarke (2003b).”
Extreme sensitivity of biological function to temperature in Antarctic marine species (2004, background): “Of the species studied, several live in excess of 40 to 50 years (Peck & Bullough 1993; Arntz et al. 1994; Brey et al. 1995; Peck & Brey 1996; Peck et al. 1997; Peck 2002).”
Physiological and ecological responses of crustaceans to ocean acidification (2011, unknown): “This is par - ticularly pertinent at polar latitudes, where marine invertebrates are stenothermal, have poor thermal tolerances and are characterised by relatively low metabolic rates (Peck 2002, Pörtner et al. 2007).”
Likely responses of the Antarctic benthos to climate-related changes in physical disturbance during the 21st century, based primarily on evidence from the West Antarctic Peninsula region. (2008, background): “Image reproduced from Peck et al. (2005). Right: actual frequencies of iceberg scouring at two contrasting sites at Adelaide Island, with grey boxes indicating periods of fast ice formation.”
Incursion and excursion of Antarctic biota: past, present and future (2006, unknown): “Ballast water taken up in the Southern Ocean and released north of the PFZ would present considerable shock to typically highly stenothermal Antarctic biota (cf. Peck, 2002).”
The HSP70 heat shock response in the Antarctic fish Harpagifer antarcticus (2007, unknown): “These animals are highly stenothermal having survivable temperature envelopes between 5°C and 12°C above the minimum sea temperature of –1.86°C (Somero and DeVries, 1967; Peck and Conway, 2000; Peck 2002).”
Reproduction in cold water: paradigm changes in the 20th century and a role for cidaroid sea urchins (2004, background): “In addition, constraints in mitochondrial function and diffusion play a role (Clarke, 1998; Peck, 2002).”
Climate-dependent evolution of Antarctic ectotherms: An integrative analysis (2006, background): “Studies within the EASIZ (Ecology of the Antarctic Sea Ice Zone) program have provided key perspectives for crucial relationships between physiological characteristics and ecological features of various Antarctic invertebrates and fish (Clarke, 1998; Pörtner et al., 2000; Peck, 2002).”
Inducible heat tolerance in Antarctic notothenioid fishes (2006, background): “Ectothermic animals endemic to Antarctic waters are markedly stenothermal; many invertebrates and fishes acclimatized to typical ambient water temperatures (‐1.8 to 2� C) have upper incipient lethal temperatures near or below 5‐6� C (Somero and DeVries 1967; Clarke and Johnston 1996; Peck 2002, 200”
Antarctic Marine Biodiversity: Adaptations, Environments and Responses to Change (2018, background): “1993, 2006b, Peck, 2002a, Markowska & Kidawa 2007); the spatangoid urchin Abatus ingens moves through sediment at 0.3–1.95 cm h−1 on average, with maximum speeds of 1.1–3.3 cm h−1 (Thomson & Riddle 2005), which compares with the temperate Echinocardium cordatum that moves at 2.0–8.0 cm h−1 and…”
Evolutionary pathways among shallow and deep-sea echinoids of the genus Sterechinus in the Southern Ocean (2011, background): “The marine fauna of the Southern Ocean substantially differs from that of other regions due to the geological history of the Antarctic continent and the extreme environmental conditions to which species are subjected (Clarke, 1983; Aronson and Blake, 2001; Peck, 2002).”
Lack of acclimation in Ophionotus victoriae: brittle stars are not fish (2009, background): “…manipulation of seawater temperatures has shown that Antarctic invertebrates, in particular, are extremely sensitive to temperature changes, with short-term survivable temperature envelopes of only between 5 and 12°C above the minimum sea temperature of ¡1.86°C (Peck and Conway 2000; Peck 2002).”
Climate Change and Invasibility of the Antarctic Benthos (2007, background): “An emphasis on brooding and lecithotrophic reproductive strategies (Pearse et al. 1991, Thorson 1950) and a trend toward gigantism (Chapelle & Peck 1999, Peck 2002) are among the unusual features of the invertebrate fauna.”
Poor acclimation capacities in Antarctic marine ectotherms (2010, background): “(SE) when the temperature that the control animals were held in was raised acutely (over a 3-day period) to 3C. The overall rise was 12.2%, and this produced a Q10 of 1.73 which is within the expected range of 1‐4 for biological systems (Clarke 1998; Peck 2002 ).”
Animal temperature limits and ecological relevance: effects of size, activity and rates of change (2009, background): “They are also characterized by slow physiological rates, growth and great age (Peck & Brey 1996; Peck 2002).”
The Antarctic notothenioid fish Pagothenia borchgrevinki is thermally flexible: acclimation changes oxygen consumption (2008, unknown): “From this, it can be argued that impairment of aerobic performance will be the most important factor determining the fate of Antarctic marine organisms in response to oceanic warming (either acclimation and survival, or relocation, or death) (Peck 2002; Peck et al. 2004; Pörtner and Knust 2007).”
