Publications

Response of subtropical coastal sediment systems of Okinawa, Japan, to experimental warming and high pCO2

International Atomic Energy Agency (IAEA) Publications

Increasing seawater temperatures and CO2 levels associated with climate change affect the shallow marine ecosystem function. In this study, the effects of elevated seawater temperature...

Publications

Nutrient pollution disrupts key ecosystem functions on coral reefs

International Atomic Energy Agency (IAEA) Publications

There is a long history of examining the impacts of nutrient pollution and pH on coral reefs. However, little is known about how these two stressors interact and influence coral reef...

Publications

Diffusion boundary layers ameliorate the negative effects of ocean acidification on the temperate coralline macroalga Arthrocardia corymbosa

International Atomic Energy Agency (IAEA) Publications

Anthropogenically-modulated reductions in pH, termed ocean acidification, could pose a major threat to the physiological performance, stocks, and biodiversity of calcifiers and may...

Publications

Variable responses of temperate calcified and fleshy macroalgae to elevated CO2 and warming

International Atomic Energy Agency (IAEA) Publications

Anthropogenic carbon dioxide (CO2) emissions simultaneously increase ocean temperatures and reduce ocean surface pH, a process termed ocean acidification (OA). OA is expected to...

Publications

Complex and interactive effects of ocean acidification and temperature on epilithic and endolithic coral-reef turf algal assemblages

International Atomic Energy Agency (IAEA) Publications

Turf algal assemblages are ubiquitous primary producers on coral reefs, but little is known about the response of this diverse group to ocean acidification (OA) across different...

Publications

Warmer more acidic conditions cause decreased productivity and calcification in subtropical coral reef sediment-dwelling calcifiers

International Atomic Energy Agency (IAEA) Publications

The effects of elevated CO2 and temperature on photosynthesis and calcification in the calcifying algae Halimeda macroloba and Halimeda cylindracea and the symbiont-bearing benthic...

Publications

An ocean acidification acclimatised green tide alga is robust to changes of seawater carbon chemistry but vulnerable to light stress

International Atomic Energy Agency (IAEA) Publications

Ulva is the dominant genus in the green tide events and is considered to have efficient CO2 concentrating mechanisms (CCMs). However, little is understood regarding the impacts of ocean...

Publications

Size-dependent physiological responses of the branching coral Pocillopora verrucosa to elevated temperature and pCO2

International Atomic Energy Agency (IAEA) Publications

Body size has large effects on organism physiology, but these effects remain poorly understood in modular animals with complex morphologies. Using two trials of a ∼24 day experiment...

Publications

The influence of abrupt increases in seawater pCO2 on plankton productivity in the subtropical North Pacific Ocean

International Atomic Energy Agency (IAEA) Publications

We conducted a series of experiments to examine short-term (2-5 days) effects of abrupt increases in the partial pressure of carbon dioxide (pCO2) in seawater on rates of primary and...

Publications

Synergistic effects of elevated carbon dioxide and sodium hypochlorite on survival and impairment of three phytoplankton species

International Atomic Energy Agency (IAEA) Publications

Sodium hypochlorite (NaOCl) is widely used to disinfect seawater in power plant cooling systems in order to reduce biofouling, and in ballast water treatment systems to prevent transport...

Publications

Symbiodinium mitigate the combined effects of hypoxia and acidification on a non-calcifying cnidarian

International Atomic Energy Agency (IAEA) Publications

Anthropogenic nutrient inputs enhance microbial respiration within many coastal ecosystems, driving concurrent hypoxia and acidification. During photosynthesis, Symbiodinium spp., the...

Effects of CO2 and seawater acidification on the early stages of Saccharina japonica development

International Atomic Energy Agency (IAEA) Publications

In this paper, we demonstrated that ocean acidification (OA) had significant negative effects on the microscopic development of Saccharina japonica in a short-term exposure experiment...

Differential responses of growth and photosynthesis in the marine diatom Chaetoceros muelleri to CO2 and light availability

International Atomic Energy Agency (IAEA) Publications

This study investigated the impact of photon flux and elevated CO2 concentrations on growth and photosynthetic electron transport on the marine diatom Chaetoceros muelleri and looked for...

Publications

CO2-driven seawater acidification increases photochemical stress in a green alga

International Atomic Energy Agency (IAEA) Publications

Increased CO2 and associated acidification in seawater, known as ocean acidification, decreases calcification of most marine calcifying organisms. However, there is little information...

Publications

Photoperiod mediates the effects of elevated CO2 on the growth and physiological performance in the green tide alga Ulva prolifera

International Atomic Energy Agency (IAEA) Publications

Ulva spp., an increasingly important food, are the dominant species of the large-scale green tides. In this study, both the growth and the physiological responses of the Ulva prolifera...

Publications

Contrasting effects of ocean acidification on tropical fleshy and calcareous algae

International Atomic Energy Agency (IAEA) Publications

Despite the heightened awareness of ocean acidification (OA) effects on marine organisms, few studies empirically juxtapose biological responses to CO2 manipulations across functionally...

Physiological response to elevated temperature and pCO2 varies across four Pacific coral species: Understanding the unique host+symbiont response

International Atomic Energy Agency (IAEA) Publications

The physiological response to individual and combined stressors of elevated temperature and pCO2 were measured over a 24-day period in four Pacific corals and their respective symbionts...
