Impacts of climate change in a global hotspot for temperate marine biodiversity and ocean warming (2011, background): “In the three decades since its arrival, previously absent urchin barrens are now extensive throughout northeastern Tasmania, and these are expected to expand further (Johnson et al., 2005).”
Sea urchin barrens as alternative stable states of collapsed kelp ecosystems (2014, unknown): “This influx of sea urchins caused areas with particularly high sea urchin densities along the northeastern coast of Tasmania to shift from a kelp-dominated (Ecklonia radiata and Phyllospora comosa) state to barrens (Johnson et al. 2005, Ling 2008, Johnson et al. 2011) (Fig.”
Population dynamics of an ecologically important range-extender: kelp beds versus sea urchin barrens (2009, background): “For incipient barrens patches at the 3 southern sites (15 to 20 m depth), average C. rodgersii density within patches ranged from ~1.5 to 3 m–2 (Johnson et al. 2005).”
Recovery of canopy-forming macroalgae following removal of the enigmatic grazing sea urchin Heliocidaris erythrogramma (2010, unknown): “…of abrasive kelps (e.g. Konar, 2000; see also Ling and r (a.) sheltered reefs (approximately b30º exposure to easterly swell) — quadrat data ximately N90º exposure to easterly swell) — data from Johnson et al., 2005 for eastern linear regressions fitted to sea urchin densities N0 individuals m−2.”
Climate change and Australian marine life (2007, background): “The establishment of long-spined sea urchins Centrostephanus rodgersii in Tasmania in the 1960s has been attributed to larval transport from northern populations by the EAC (Johnson et al. 2005).”
Global regime shift dynamics of catastrophic sea urchin overgrazing (2015, background): “While widespread urchin barrens (100 000s m(2)) are evident at several eastern Tasmanian reefs, smaller ‘incipient barrens’ (10s m(2)) within otherwise intact kelp beds are common and considered an early warning sign of broader-scale kelp bed collapse along this coast [7,19].”
Variation in the morphology, reproduction and development of the habitat-forming kelp Ecklonia radiata with changing temperature and nutrients (2013, background): “…include the range expansion of the barrens-forming sea urchin Centrostephanus rodgersii, which is impacting sub - tidal kelp forests in Tasmania (Johnson et al. 2005, Ling et al. 2009a,b), and range shifts in a number of macroalgae (Wernberg et al. 2011) including the contraction and reduction…”
Climate‐driven range extension of a sea urchin: inferring future trends by analysis of recent population dynamics (2009, methodology): “rodgersii to Tasmania may have occurred due to increased larval dispersal (Andrew & Byrne, 2001; Johnson et al., 2005) driven by the poleward advance of the EAC by 350 km over the past 60 years (Ridgway, 2007a).”
