Gene expression of Pocillopora damicornis coral larvae in response to acidification and ocean warming

Objectives The endosymbiosis with Symbiodiniaceae is key to the ecological success of reef-building corals. However, climate change is threatening to destabilize this symbiosis on a global scale. Most studies looking into the response of corals to heat str ...

Thermal Stress Interacts With Surgeonfish Feces to Increase Coral Susceptibility to Dysbiosis and Reduce Tissue Regeneration

Leïla Ezzat

Dysbiosis of coral microbiomes results from various biotic and environmental stressors, including interactions with important reef fishes which may act as vectors of opportunistic microbes via deposition of fecal material. Additionally, elevated sea surfac ...

Nutrient pollution enhances productivity and framework dissolution in algae- but not in coral-dominated reef communities

Nils Rädecker, Hal Hunt Jones II

Ecosystem services provided by coral reefs may be susceptible to the combined effects of benthic species shifts and anthropogenic nutrient pollution, but related field studies are scarce. We thus investigated in situ how dissolved inorganic nutrient enrich ...

Persistence of bioconvection-induced mixed layers in a stratified lake

Alfred Johny Wüest, Damien Bouffard, Oscar Rodrigo Sepúlveda Steiner

In situ observations of biophysical interactions in natural waters typically focus on physical mechanisms influencing biological activity. Yet, biological activity can also drive physical processes in aquatic environments. A community of photoautotrophic, ...

Primary and Net Ecosystem Production in a Large Lake Diagnosed From High-Resolution Oxygen Measurements

Alfred Johny Wüest, Camille Roland Marie Minaudo, Bieito Fernandez Castro, Hannah Elisa Chmiel, Shubham Krishna, Pascal Perolo

The rates of gross primary production (GPP), ecosystem respiration (R), and net ecosystem production (NEP) provide quantitative information about the cycling of carbon and energy in aquatic ecosystems. In lakes, metabolic rates are often diagnosed from die ...

Carbon turnover and microbial activity in an artificial soil under imposed cyclic drainage and imbibition

Tatjana Milojevic

Water table fluctuations generate temporally and spatially dynamic physicochemical conditions that drive biogeochemical hot spots and hot moments in the vadose zone. However, their role in the cycling of soil C remains poorly known. Here, we present result ...

A modern scleractinian coral with a two-component calcite–aragonite skeleton

Anders Meibom, Jaroslaw Hubert Stolarski

One of the most conserved traits in the evolution of biomineralizing organisms is the taxon-specific selection of skeletal minerals. All modern scleractinian corals are thought to produce skeletons exclusively of the calcium-carbonate polymorph aragonite. ...

Optimizing Mesostructured Silver Catalysts for Selective Carbon Dioxide Conversion into Fuels

Sophia Haussener, Silvan Suter

Mesostructured silver catalysts have shown a substantial rise in reaction selectivity for the conversion of CO2 into fuels with increasing thickness of ordered, inverse-opal films. The challenge lies in the optimization of the morphology to maximize the CO ...

Reactivity and Performance of Limestone Calcined-Clay Cement (LC3) Cured at Low Temperature

Karen Scrivener, Franco Alberto Zunino Sommariva

Limestone calcined-clay cements (LC3) take advantage of the synergetic effects of calcium carbonate reaction with the additional aluminium provided by the calcined clay. As temperature decreases, calcium carbonate solubility increase, therefore, the early- ...

Influence of calcium and magnesium carbonates on hydration kinetics, hydrate assemblage and microstructural development of metakaolin containing composite cements

Mohsen Ben Haha, Pawel Tadeusz Durdzinski

The hydration of metakaolin composite cements containing quartz, natural limestone and dolomite rock is studied using a multi-method approach and modelling. The study demonstrates that the calcite present in limestone and dolomite rock is very reactive. Co ...
