Shifting paradigms in restoration of the world's coral reefs

Global Change Biology, Год журнала: 2017, Номер 23(9), С. 3437 - 3448

Опубликована: Март 1, 2017

Abstract Many ecosystems around the world are rapidly deteriorating due to both local and global pressures, perhaps none so precipitously as coral reefs. Management of reefs through maintenance (e.g., marine‐protected areas, catchment management improve water quality), restoration, well national governmental agreements reduce greenhouse gas emissions 2015 Paris Agreement) is critical for persistence Despite these initiatives, health abundance corals declining other solutions will soon be required. We have recently discussed options using assisted evolution (i.e., selective breeding, gene flow, conditioning or epigenetic programming, manipulation microbiome) a means enhance environmental stress tolerance success reef restoration efforts. The 2014–2016 bleaching event has sharpened focus on such interventionist approaches. highlight necessity consideration alternative hybrid) ecosystem states, discuss traits resilient ecosystems, propose decision tree incorporating into initiatives climate resilience

Approaches to defining a planetary boundary for biodiversity

Rockstrom et al. (2009) identify nine such boundaries highlight biodiversity loss as being single boundary where current rates extinction furthest space. Here we review evidence to based on weaknesses with this metric its bearing humanity's needs.

The Power of Three: Coral Reefs, Seagrasses and Mangroves Protect Coastal Regions and Increase Their Resilience

PLoS ONE, Год журнала: 2016, Номер 11(7), С. e0158094 - e0158094

Опубликована: Июль 13, 2016

Natural habitats have the ability to protect coastal communities against impacts of waves and storms, yet it is unclear how different complement each other reduce those impacts. Here, we investigate individual combined protection services supplied by live corals on reefs, seagrass meadows, mangrove forests during both non-storm storm conditions, under present future sea-level conditions. Using idealized profiles fringing barrier quantify these using various metrics inundation erosion. We find that, together, corals, seagrasses, mangroves supply more than any habitat or combination two habitats. Specifically, while are most effective at protecting coast seagrasses also moderate impact thereby further reducing vulnerability regions. Also, in addition structural differences, amount service our analysis highly dependent geomorphic setting, location forcing conditions: reef profile seagrasses; corals; simulations, can even compensate for long-term degradation reef. Results this study demonstrate importance taking integrated place-based approaches when quantifying managing ecosystems.

Climate Change, Coral Loss, and the Curious Case of the Parrotfish Paradigm: Why Don't Marine Protected Areas Improve Reef Resilience?

Annual Review of Marine Science, Год журнала: 2019, Номер 11(1), С. 307 - 334

Опубликована: Янв. 3, 2019

Scientists have advocated for local interventions, such as creating marine protected areas and implementing fishery restrictions, ways to mitigate stressors limit the effects of climate change on reef-building corals. However, in a literature review, we find little empirical support notion managed resilience. We outline some reasons why protection herbivorous fish (especially parrotfish) had effect coral One key explanation is that impacts (e.g., pollution fishing) are often swamped by much greater ocean warming Another sheer complexity (including numerous context dependencies) five cascading links assumed managed-resilience hypothesis. If reefs cannot be saved actions alone, then it time face reef degradation head-on, directly addressing anthropogenic change—the root cause global decline.

Warm-water coral reefs and climate change

Science, Год журнала: 2015, Номер 350(6262), С. 769 - 771

Опубликована: Ноя. 12, 2015

Coral reefs are highly dynamic ecosystems that regularly exposed to natural perturbations. Human activities have increased the range, intensity, and frequency of disturbance reefs. Threats such as overfishing pollution being compounded by climate change, notably warming ocean acidification. Elevated temperatures driving increasingly frequent bleaching events can lead loss both coral cover reef structural complexity. There remains considerable variability in distribution threats ability survive or recover from disturbances. Without significant emissions reductions, however, future is bleak.
