2017“Fertilization&Activation of Development”戈登学术会议（The 2017 Gordon Research Conference on Fertilization&Activation of Development ）
2017 Fertilization&Activation of Development 戈登学术会议
2017/2/14
The union of egg and sperm creates a new totipotent cell – the zygote. In addition to starting the development of a new organism, fertilization also provides an excellent system in which to investigat...

Mathematics of gamete diffusion and fertilization in aquatic habitats
Over the past 20 years there has been growing interest in the concept of fertilizing the ocean with iron to abate global warming. This interest was catalyzed by basic scientific experiments showing th...
Characterization of the sperm factor responsible for initiating [Ca2+]i oscillations during fertilization in mammalian eggs
Biological sciences Sperm factor Oscillations Fertilization Mammalian eggs
2015/1/28
During fertilization the sperm activates the mammalian egg by eliciting [Ca2+]i oscillations. However, how the sperm triggers [Ca2+]i oscillations in mammalian eggs remains unknown. To test the possib...
Near-future levels of ocean acidification do not affect sperm motility and fertilization kinetics in the oyster Crassostrea gigas
Near-future levels ocean acidification sperm motility and fertilization kinetics the oyster Crassostrea gigas
2010/1/21
An increasing number of studies are now reporting the effects of ocean acidification on a broad range of marine species, processes and systems. Many of these are investigating the sensitive early life...
Effects of N and P fertilization on the greenhouse gas exchange in two northern peatlands with contrasting N deposition rates
N and P fertilization greenhouse gas exchange northern peatlands N deposition rates
2010/1/21
Peatlands are important ecosystems in the context of biospheric feedback to climate change, due to the large storage of organic C in peatland soils. Nitrogen deposition and increased nutrient availabi...
Impact of atmospheric and terrestrial CO2 feedbacks on fertilization-induced marine carbon uptake
atmospheric and terrestrial CO2 feedbacks fertilization-induced marine carbon uptake
2010/1/20
The sensitivity of oceanic CO2 uptake to alterations in the marine biological carbon pump, such as brought about by natural or purposeful ocean fertilization, has repeatedly been investigated by studi...
Mineral fertilization did not affect decay of old lignin and SOC in a 13C-labeled arable soil over 36 years
Mineral fertilization decay lignin SOC 13C-labeled arable soil
2010/1/20
Retardation of soil organic carbon (SOC) decay after nitrogen addition to litter or soil has been suggested in several recent studies and has been attributed to a retardation in lignin decay. With our...
Ammonia fluxes in relation to cutting and fertilization of an intensively managed grassland derived from an inter-comparison of gradient measurements
Ammonia fluxes cutting fertilization grassland inter-comparison gradient measurements
2010/1/20
Quantification of ammonia (NH3) land-atmosphere exchange is required for atmospheric modelling and assessment of nitrogen deposition, yet flux measurement methods remain highly uncertain. To address t...
Stage-specific Expression of Lanosterol 14-Demethylase in Mouse Oocytes in Relation to Fertilization and Embryo Development Competence
Mouse Oocyte Lanosterol 14 -Demethylase In vitro Fertilization Early Embryo Development
2016/4/29
Follicular fluid meiosis-activating sterol (FF-MAS) has been suggested as a positive factor which could improve the oocyte quality and subsequent embryo development after in vitro fertilization. Howev...
Effect of water addition and nitrogen fertilization on the fluxes of CH4, CO2, NOx, and N2O following five years of elevated CO2 in the Colorado Shortgrass Steppe
nitrogen fertilization CH4 CO2 NOx N2O Colorado Shortgrass Steppe
2009/3/11
An open-top-chamber (OTC) CO2 enrichment (~720 mmol mol-1) study was conducted in the Colorado shortgrass steppe from April 1997 through October 2001. Aboveground plant biomass increased under elevate...
