Dornelas et al 2006
Compared natural distribution stony corals to simulated neutral models and found that spatio-temporal environmental stochasticity is major driver of diversity patterns on coral reefs
Bellwood et al. 2004
Came up with the ball metaphor to describe states in marine ecosystems - specifically was looking at how chronic disturbances led to vulnerability to acute stress in context of sea urchins
Pratchett et al. 2020
found directional shifts in coral assemblages
Pratchett et al. 2016
found negative relationship between polyp size and bleaching susceptibility –> heterotrophy?
Pratchett et al. 2014
Found COTS outbreaks occur after droughts, 2-5 years after flooding
Swearman 2008
Reefs with COTS outbreaks are less severe in no-take zones
Gilmour et al. 2013
Found that amount of recruitment mirrors amount of coral coverage (directly proportional)
Ortiz et al. 2018
Recovery has Decreased by 84% in GBR between 1992-2010
Halford et al. 2004
Coral coverage can recover within 5-10 years
McWilliam et al 2018
Facilitation between corals has been recorded as multispecies group have higher productivity than monocultures
Roth et al 2020
Pioneer communities have high carbon and nitrogen fixation
Hall et al. 2001
Healing of coral tissues takes about 12 days. Slow healing due to colonization of algae
Albany et al. 2004
Predator exclusion enhances recruitment of fish and additional removal of competitors enhanced it even more
Bond et al. 2018
Predators have greatest influence on prey when predation is concentrated on a few species – therefore trophic cascades more probable when predation is focused on a single trophic leve
Madin et al. 2020
Found at 4/24 coral reef sites that there’s fewer predators, there’s less coral
Hoeksema & de Voogd 2012
Free-living corals wriggle away from competitors; therefore competition must exist within coral reefs
Desbiens et al. 2021
“The diversity of species within coral reef food webs and their associations with bottom-up drivers likely buffers against trophic cascading across GBR functional guilds when reef shark assemblages are depleted, as has been demonstrated in other complex ecosystems.”
Svensson et al. 2017
Found implementing warming conditions collapsed a 4 tier trophic chain down to 3 in algal marine system (artificially heated Baltic Sea)
Hoegh-Guldberg et al. 2017
climate change initially impacts warm water reefs and models have projected decimation of these systems as soon as 2040/50 and risk of mass bleaching events is steadily increasing also looked at acidification and found coral calcification has reduced 14.2% since 1990 in GBR
Hughes et al. 2017
450 CO2 tipping point –> phase shift towards algae dominated reefs
Death et al. 2012
27 year decline of coral reefs of the GBR - lists all the problems, causes, and projections - when in doubt, De’ath
Hughes et al. 2019
Found that fish communities were more biodiverse with more biodiverse corals/benthic community. Found more frequent bleaching events in GBR
