Exposure to elevated sea-surface temperatures below the bleaching threshold impairs coral recovery and regeneration following injury [PDF]
PeerJ, 2017 Elevated sea surface temperatures (SSTs) are linked to an increase in the frequency and severity of bleaching events due to temperatures exceeding corals’ upper thermal limits. The temperatures at which a breakdown of the coral-Symbiodinium endosymbiosis

Protecting temperate old‐growth forests as biotic microrefugia amid climate change
Conservation Science and Practice, EarlyView.Old‐growth forests are essential biotic microrefugia, providing high carbon storage, biodiversity, and stable microclimates that protect understorey species from climatic extremes. Their resilience to drought and disturbance makes them more effective than younger forests, yet habitat loss, fragmentation, and climate change increasingly threaten these ...

The 27–year decline of coral cover on the Great Barrier Reef and its causes [PDF]
, 2012 This study investigates the spatial and temporal dynamics of coral cover, identifies the main drivers of coral mortality, and quantifies the rates of potential recovery of the Great Barrier Reef.The world’s coral reefs are being degraded, and the need to

Coral-dwelling fish moderate bleaching susceptibility of coral hosts.
PLoS ONE, 2018 Global environmental change has the potential to disrupt well established species interactions, with impacts on nutrient cycling and ecosystem function. On coral reefs, fish living within the branches of coral colonies can promote coral performance, and ...

Journal of Agrarian Change, EarlyView.ABSTRACT Following recent calls to deepen understanding of the Global Pesticide Complex, this article delves into the China‐to‐Australia supply chain of a single herbicide—paraquat. First released in the United Kingdom in the 1960s, acutely toxic paraquat is now primarily produced in China.

Bleaching susceptibility and recovery of Colombian Caribbean corals in response to water current exposure and seasonal upwelling. [PDF]
PLoS ONE, 2013 Coral bleaching events are globally occurring more frequently and with higher intensity, mainly caused by increases in seawater temperature. In Tayrona National Natural Park (TNNP) in the Colombian Caribbean, local coral communities are subjected to ...

Evidence for mitigation of coral bleaching by manganese [PDF]
Scientific Reports, 2018 AbstractUnprecedented mass coral bleaching events due to global warming and overall seawater pollution have been observed worldwide over the last decades. Although metals are often considered as toxic substances for corals, some are essential at nanomolar concentrations for physiological processes such as photosynthesis and antioxidant defenses.

Journal of Phycology, EarlyView.Abstract The mesophotic zone off Tanegashima Island (approximately 30–40 m deep) is a marine macroalgal hotspot in subtropical Japan; however, the taxonomic diversity of calcifying red algal community remains poorly understood. Our phylogenetic analyses based on psbA, rbcL, and COI‐5P gene markers disclosed the presence of at least 12 rhodolith‐forming

Coral Bleaching: A Colorful Struggle for Survival [PDF]
Current Biology, 2020 An optical feedback loop involving the coral host and its photosynthetic microalgal symbionts is responsible for the extreme coloration of corals during certain bleaching events. Colorful bleaching occurs after brief or mild exposure to heat or nutrient stress. Importantly, it can indicate good recovery prospects for the affected corals.

Understanding marine biodiversity patterns and drivers: The fall of Icarus
Marine Ecology, EarlyView.Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.
