A low oxygen threshold for physiological responses and trace metal quotas of Prochlorococcus and Synechococcus

open access: yesLimnology and Oceanography, EarlyView.
Abstract Continued human activity is expected to accelerate ocean deoxygenation, leading to the expansion and shallowing of oxygen‐deficient zones (ODZs). This decline in oxygen may impact both phytoplankton growth and trace metal uptake. We conducted culture experiments with Prochlorococcus MIT9313 and Synechococcus XM‐24, two numerically dominant ...

Timing of calcification and environmental variability determine pH proxy fidelity in coastal calcifying macroalgae

open access: yesLimnology and Oceanography, EarlyView.
Abstract Long‐lived calcifying marine biota are increasingly used as paleo‐archives for reconstructing ocean pH. They enable exploration of the rate and magnitude of ocean acidification in shallow‐water ecosystems serving as proxies for environmental pH reconstruction.

Revisiting the silicon isotopic signal of sponge skeletons and its implications

open access: yesLimnology and Oceanography, EarlyView.
Abstract This study investigates the relationship between the silicon (Si) isotopic composition of sponge skeletal silica (δ30SibSi) and seawater characteristics in sponge habitats, specifically the concentration of dissolved silicic acid and its Si isotopic signature (δ30SidSi).

Marine protected areas increase resilience among coral reef communities.

open access: yesEcology Letters, 2016
With marine biodiversity declining globally at accelerating rates, maximising the effectiveness of conservation has become a key goal for local, national and international regulators.

Heterotrophic dependence and bidirectional metabolite exchange dynamics in a temperate coral

open access: yesLimnology and Oceanography, EarlyView.
Abstract In temperate ecosystems, where cold, turbid waters constrain symbiotic potential, corals have evolved facultative symbiosis, providing an opportunity to explore coral energetics in the face of global climate change. We conducted an in situ light exclusion experiment on the facultatively symbiotic temperate coral Astrangia poculata to explore ...

Ascidians increase in abundance on tropicalized reefs and may enhance benthic nitrous oxide production

open access: yesLimnology and Oceanography, EarlyView.
Abstract Nitrous oxide (N2O) is an ozone‐depleting greenhouse gas that has a global warming potential nearly 300 times greater than carbon dioxide. Although the oceans contribute about 21% of atmospheric global N2O emissions, we know relatively little about N2O dynamics in nearshore systems. Here, we document the fourfold increase in the abundance of a

Harnessing nature's buffer: Assessing the role of bivalve shells in coastal alkalinity regeneration

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Bivalve shells, a natural alkaline material, play a crucial role in coastal carbon cycles by influencing total alkalinity (TA) and dissolved inorganic carbon (DIC). This study investigated oyster shell dissolution in Narragansett Bay, Rhode Island, under varying pCO2 conditions, revealing TA regeneration rates of 4–56 μmol L−1 d−1, which could

Microbial and transcriptional response of Acropora valida and Turbinaria peltata to Vibrio coralliilyticus challenge: insights into corals disease resistance

open access: yesBMC Microbiology
Background Coral diseases are significant drivers of global coral reef degradation, with pathogens dominated by Vibrio coralliilyticus playing a prominent role in the development of coral diseases.

Production and fate of macroalgal carbon in the ocean: How much do macroalgal organics matter?

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Global carbon sequestration by macroalgae is hypothesized to rival rates in other blue carbon ecosystems. However, quantifying macroalgal carbon sequestration is challenging as it is hypothesized to occur outside macroalgal ecosystems, with 73% of sequestration occurring when dissolved organic carbon (DOC) is exported to deep ocean waters.
