El Niño, grazers and fisheries interact to greatly elevate extinction risk for Galapagos marine species (2010, background): “Studies elsewhere indicate that urchin barrens typically develop at sites with urchin densities exceeding about 3 m 2 and are maintained at densities 41 m 2 (Tegner & Dayton, 2000; Shears & Babcock, 2003).”
Burdens of evidence and the benefits of marine reserves: putting Descartes before des horse? (2003, result): “& Babcock 2002; Shears & Babcock 2003; Willis et al. 2003).”
Structure of cryptic reef fish assemblages: relationships with habitat characteristics and predator density (2003, positive): “Thus, the coverage of urchin-grazed ‘barrens’ habitat within reserves has declined markedly, to be replaced by kelp forest (Babcock et al. 1999, Shears & Babcock 2002, 2003).”
Global regime shift dynamics of catastrophic sea urchin overgrazing (2015, background): “increased urchin foraging rates causing high mortality of juvenile kelp [35,47]”
Effects of marine reserves and urchin disease on southern Californian rocky reef communities (2004, background): “This appears to be due to indirect effects of the fishery, which cascade down the food chain to produce a community shift (fisherylobsters-urchins-kelp: Shears & Babcock 2002, 2003).”
Relationships between rocky-reef fish assemblages, the sea urchin Diadema antillarum and macroalgae throughout the Canarian Archipelago (2004, background): “…2001, Tuya et al. 2004b); as well as for other echinoid species in the western Mediterranean (Sala & Boudouresque 1997), the Kenyan coast (McClanahan et al. 1996), New Zealand (Andrew & Choat 1982, Babcock et al. 1999, Shears & Babcock 2003) and in the north-western Atlantic (Vadas & Steneck 1995).”
Integrating ecology with biogeography using landscape characteristics: a case study of subtidal habitat across continental Australia (2008, background): “…to those of eastern Australia, the cessation of fishing in Marine Protected Areas was associated with an increase in densities of predators and a concomitant decline of herbivores (i.e. urchins and urchin barrens) and widespread expansion of forests (Babcock et al., 1999; Shears & Babcock, 2003).”
Host density thresholds and disease control for fisheries and aquaculture (2010, background): “Meanwhile, there are large increases in the abundance of other species due to trophic cascades associated with fisheries (Shears & Babcock 2003, Myers et al. 2007), as well as the rapid growth of marine aquaculture (Goldburg & Naylor 2005, Duarte et al. 2007).”
The effects of predator abundance and habitat structural complexity on survival of juvenile sea urchins (2005, background): “In marine reserves, where predatory fishes are more abundant and larger than in unprotected areas (e.g. Halpern and Warner 2002), sea urchin densities are generally lower than outside the reserves (McClanahan and Muthiga 1989; Sala and Zabala 1996; Shears and Babcock 2002, 2003).”
Resonating sea urchin skeletons create coastal choruses (2008, background): “In addition to direct fishing pressure, coastal urchin populations have been dramatically affected by trophic cascades resulting from harvesting of predators in some locations (Shears & Babcock 2003, Guidetti 2006).”
