Anthropogenic climate change presents a major challenge to coastal ecosystems. Mass population declines or geographic shifts in species ranges are expected occur, potentially leading wide-scale ecosystem disruption collapse. This is particularly important for habitat-forming such as free-living non-geniculate coralline algae that aggregate form large, structurally complex reef-life ecosystems with high associated biodiversity and carbon sequestration capability. Coralline algal beds have worldwide distribution, but recently experienced global due anthropogenic pressures changing environmental conditions. However, the factors controlling bed distribution remain poorly understood, limiting our ability make adequate assessments of how populations may future. We constructed first model (focusing on maerl-forming including crustose beds) showed bathymetry, temperature at seabed light availability primary drivers present-day distribution.

Coral carbonate production is fundamental to reef accretion and, consequently, the preservation of essential ecosystem services, such as wave attenuation and sustained biodiversity. However, unprecedented loss coral reefs from anthropogenic impacts has put these valuable services at risk. To counteract this loss, active rehabilitation degraded sites accelerated globally.

Coral reefs are deteriorating worldwide prompting reef managers and stakeholders to increasingly explore new management tools. Following back-to-back bleaching in 2016/2017, multi-taxa coral nurseries were established 2018 for the first time on Great Barrier Reef (GBR) aid maintenance restoration at a “high-value” location–Opal Reef–frequented by tourism industry. Various species (n = 11) propagated within shallow water (ca. 4-7m) platforms installed across two sites characterised differing environmental exposure–one adjacent deep-water channel (Blue Lagoon) one that was relatively sheltered (RayBan). Growth rates of fragments placed onto highly variable taxa but generally higher Blue Lagoon (2.1–10.8 cm 2 month -1 over 12 months) compared RayBan (0.6–6.6 9 months). largely independent season, except Acropora tenuis hyacinthus , where growth 15–20% December 2018-July 2019 (“warm season”) August-December (“cool season”). Survivorship all 2,536 nursery ca. 80–100%, with some exhibiting survivorship ( loripes Porites cylindrica ) others A . Montipora hispida ). Parallel measurements used determine relative return-on-effort (RRE) scores as an integrated metric “success” accounting life history trade-offs, complementing mutually exclusive assessment or survivorship.

Intact and functioning, they useful, but when compromised lose their utility often heritage significance. At this point, at best insignificant worst destructive, as toxic that damages other values. This chapter presents stress-strain curve framework introduces temporal perspective on damage being done. recognises over time materials pass through phase elasticity (in which remediation can bring things back to 'original' form) towards plasticity (whereby retain an aspect original forever changed) ultimately fracture (where thing becomes irretrievably broken).

For millennia, coastal and marine ecosystems have adapted flourished in the Red Sea’s unique environment. Surrounded by deserts on all sides, Sea is subjected to high dust inputs receives very little freshwater input, so harbors a salinity. Coral reefs, seagrass meadows, mangroves flourish this environment provide socio-economic environmental benefits bordering coastlines countries. Interestingly, while coral reef are currently experiencing rapid decline global scale, those appear be relatively better shape. That said, they certainly not immune stressors that cause degradation, such as increasing ocean temperature, acidification pollution. In many regions, already severely deteriorating further threatened population pressure large development projects. Degradation of these habitats will lead costs, well significant economic losses. Therefore, it result missed opportunity for countries develop sustainable blue economy integrate innovative nature-based solutions.
