Microarray Analysis of Genes Involved with Shell Strength in Layer Shell Gland at the Early Stage of Active Calcification
Chicken Microarray Differentially Expressed Genes Eggshell Strength
2016/5/11
The objective of this study was to get a comprehensive understanding of how genes in chicken shell gland modulate eggshell strength at the early stage of active calcification. Four 32-week old of pure...

Resilience of pore-water chemistry calcification in photosyntheticzones calcifying sediments
2014/4/16
Photosynthetically driven calcification was investigated in diatom-dominated carbonate sediments from Bait Reef, Australia. Laboratory measurements conducted over complete diel cycles, using O2, pH, C...
Effect of carbonate ion concentration and irradiance on calcification in planktonic foraminifera
carbonate ion concentration and irradiance calcification planktonic foraminifera
2010/1/21
The effect of carbonate ion concentration ([CO32−]) on calcification rates estimated from shell size and weight was investigated in the planktonic foraminifera Orbulina universa and Globigerinoi...
Impact of seawater pCO2 on calcification and Mg/Ca and Sr/Ca ratios in benthic foraminifera calcite: results from culturing experiments with Ammonia tepida
seawater pCO2 calcification and Mg/Ca and Sr/Ca ratios benthic foraminifera calcite culturing experiments Ammonia tepida
2010/1/21
Evidence of increasing concentrations of dissolved carbon dioxide, especially in the surface ocean and its associated impacts on calcifying organisms, is accumulating. Among these organisms, benthic a...
Physiological controls on seawater uptake and calcification in the benthic foraminifer Ammonia tepida
Physiological controls seawater uptake calcification benthic foraminifer Ammonia tepida
2010/1/21
To analyze the relation between seawater uptake and calcification, we incubated juveniles of the benthic foraminifer Ammonia tepida with various fluorescent probes and visualised them afterwards with ...
From laboratory manipulations to Earth system models:scaling calcification impacts of ocean acidification
laboratory manipulations Earth system models calcification impacts ocean acidification
2010/1/21
The observed variation in the calcification responses of coccolithophores to changes in carbonate chemistry paints a highly incoherent picture, particularly for the most commonly cultured "species", E...
Calcification of the cold-water coral Lophelia pertusa,under ambient and reduced pH
Calcification cold-water coral Lophelia pertusa ambient and reduced pH
2010/1/20
The cold-water coral Lophelia pertusa is one of the few species able to build reef-like structures and a 3-dimensional coral framework in the deep oceans. Furthermore, deep cold-water coral bioherms m...

Inferred level calcification decreases along increasing temperature gradient Mediterranean endemic coral
2014/4/18
The correlation between solar radiation and sea surface temperature (SST) and growth was assessed along a latitudinal gradient. Extension rate and skeletal density were both correlated with calcificat...
