Immediate Effects of Hurricanes on a Diverse Coral/Mangrove Ecosystem in the U.S. Virgin Islands and the Potential for Recovery

open access: yesDiversity, 2019
Hurricanes Irma and Maria, two powerful storms that hit the U.S. Virgin Islands less than 2 weeks apart in September 2017, caused extensive damage to the natural resources on St. John.

Water contamination reduces the tolerance of coral larvae to thermal stress [PDF]

open access: yes, 2010
Coral reefs are highly susceptible to climate change, with elevated sea surface temperatures (SST) posing one of the main threats to coral survival.

Marine Skeletons: Towards Hard Tissue Repair and Regeneration

open access: yesMarine Drugs, 2018
Musculoskeletal disorders in the elderly have significantly increased due to the increase in an ageing population. The treatment of these diseases necessitates surgical procedures, including total joint replacements such as hip and knee joints.

Human impact on atolls leads to coral loss and community homogenisation : a modeling study [PDF]

open access: yes, 2012
We explore impacts on pristine atolls subjected to anthropogenic near-field (human habitation) and far-field (climate and environmental change) pressure.

Coral skeleton P/Ca proxy for seawater phosphate: Multi-colony calibration with a contemporaneous seawater phosphate record [PDF]

open access: yes, 2010
A geochemical proxy for surface ocean nutrient concentrations recorded in coral skeleton could provide new insight into the connections between sub-seasonal to centennial scale nutrient dynamics, ocean physics, and primary production in the past ...

Effect of fine-scale habitat differences on algal colonisation in a coral-dominated subtropical reef

open access: yesAnais da Academia Brasileira de Ciências, 2021
Maintaining the coexistence of algae and corals depends on the interactions between them. We investigated these interactions to assess: (1) recruitment patterns of algal turfs over time in dead areas on live corals; (2) the influence of fine-scale ...

Keep up or drown: adjustment of western Pacific coral reefs to sea-level rise in the 21st century [PDF]

open access: yesRoyal Society Open Science, 2015
Since the Mid-Holocene, some 5000 years ago, coral reefs in the Pacific Ocean have been vertically constrained by sea level. Contemporary sea-level rise is releasing these constraints, providing accommodation space for vertical reef expansion.

18O Fractionation in the coralline aragonite of Porites lobata: Implications in oceanic paleothermometry studies

open access: yesCiencias Marinas, 1994
This study is fundamentally focused on a simple, but relatively unpondered problem: the coral δ18O temperature sensitivity (dδ/dT). Previous paleotemperature studies of corals have involved the use of either: 1) the calcite’s δ18O temperature ...

Laboratory Assessment of the Impact of Chemical Oxidation, Mineral Dissolution, and Heating on the Nitrogen Isotopic Composition of Fossil‐Bound Organic Matter

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Fossil‐bound organic material holds great potential for the reconstruction of past changes in nitrogen (N) cycling. Here, with a series of laboratory experiments, we assess the potential effect of oxidative degradation, fossil dissolution, and thermal ...

Coral Reef Ecosystems under Climate Change and Ocean Acidification

open access: yesFrontiers in Marine Science, 2017
Coral reefs are found in a wide range of environments, where they provide food and habitat to a large range of organisms as well as providing many other ecological goods and services.
