Stable Sr isotope (88Sr/86Sr) fractionation in calcite precious corals

open access: yesFrontiers in Marine Science, 2022
Stable isotope ratios of Sr (88Sr/86Sr) are a novel indicator for identifying terrestrial and oceanic Sr cycling and biological processes. Here we evaluate the temperature dependence of stable Sr isotope ratios (δ88Sr) in the calcite skeletons of ...

Cell death and degeneration in the symbiotic dinoflagellates of the coral Stylophora pistillata during bleaching [PDF]

open access: yes, 2004
Rising sea temperatures are increasing the incidences of mass coral bleaching (the dissociation of the coral–algal symbiosis) and coral mortality. In this study, the effects of bleaching (induced by elevated light and temperature) on the condition of ...

Diminutive Colon polyp Coexisting with a Large Lipoma: An Endoscopic 'Rarity'

open access: yesCanadian Journal of Gastroenterology, 2004
Lipomas are the most common nonepithelial tumours of the gastrointestinal tract. In the colon, however, lipomas are uncommon. Herein we report the case of a patient who had a large colonic lipoma with an overlying bleeding diminutive colon polyp that ...

Patterns of Sponge Abundance Across a Gradient of Habitat Quality in the Wakatobi Marine National Park, Indonesia [PDF]

open access: yes, 2011
Sponges are important components of reef communities worldwide, fulfilling a number of important functional roles. Habitat degradation caused by the loss of hard corals has the potential to cause increases in sponge abundance and percentage cover as they

Comparative study of Steel-FRP, FRP and steel reinforced coral concrete beams in their flexural performance [PDF]

open access: yes, 2020
In this paper, a comparative study of Carbon Fiber Reinforced Polymer (CFRP) Bar and Steel-Carbon Fiber Composite Bar (SCFCB) reinforced coral concrete beams are made through a series experimental tests and theoretical analysis.

Patient-Reported Knee Outcome Scores With Soft Tissue Quadriceps Tendon Autograft Are Similar to Bone–Patellar Tendon–Bone Autograft at Minimum 2-Year Follow-up: A Retrospective Single-Center Cohort Study in Primary Anterior Cruciate Ligament Reconstruction Surgery

open access: yesOrthopaedic Journal of Sports Medicine, 2019
Background: Quadriceps tendon (QT)–bone autografts used during anterior cruciate ligament (ACL) reconstruction have provided comparable outcomes and decreased donor-site morbidity when compared with bone–patellar tendon–bone (BPTB) autografts.

Coral Reef Recovery in the Mexican Caribbean after 2005 Mass Coral Mortality—Potential Drivers

open access: yesDiversity, 2020
In 2005, an extreme heatwave hit the Wider Caribbean, followed by 13 hurricanes (including hurricanes Emily and Wilma) that caused significant loss in hard coral cover. However, the drivers of the potential recovery are yet to be fully understood.

From citizen science to policy development on the coral reefs of Jamaica [PDF]

open access: yes, 2012
This paper explores the application of citizen science to help generation of scientific data and capacity-building, and so underpin scientific ideas and policy development in the area of coral reef management, on the coral reefs of Jamaica. From 2000 to

Genomic signatures of host-associated divergence and adaptation in a coral-eating snail, Coralliophila violacea (Kiener, 1836). [PDF]

open access: yes, 2020
The fluid nature of the ocean, combined with planktonic dispersal of marine larvae, lowers physical barriers to gene flow. However, divergence can still occur despite gene flow if strong selection acts on populations occupying different ecological niches.
