Dr Hawkings added: "Our findings re-frame the traditional view of the importance of ice sheets in biogeochemical cycles, specifically of the silica cycle.
The finding, which was published in Global Biogeochemical Cycles, provides new insight into the relationship between coastal waters and climate, and should also help scientists better understand shoreline processes like acidification, hypoxia, and tidal wetland loss.
The topics include the potential impacts of climate change on biodiversity in flowing freshwater systems, the ecology of mating and its evolutionary consequences in seed plants, anthropogenic extinction dominates Holocene declines of West Indian mammals, ecosystem process and biogeochemical cycles in secondary tropical forest succession, and innate receiver bias: its role in the ecology and evolution of plant-animal interaction.
Now, a new study, published Monday in the journal (http://onlinelibrary.wiley.com/doi/10.1002/2015GB005327/full) Global Biogeochemical Cycles  has revealed that Florida's coral reef - the only living coral reef in the continental United States - is starting to disintegrate due to ocean acidification.
While talking to students, Dr Anjum Nasim Sabri said that study of ecosystems and biogeochemical cycles was very important and one could understand the importance of environment protection only with the knowledge of the factors that operate in an ecosystem.
They added that this suggests that major human impacts on global biogeochemical cycles go back well before dawn of the agriculture.
They cover the elements in the Solar System, meteorites, the solar nebula, the bodies in the inner Solar System, terrestrial atmospheric chemistry, the greenhouse effect and biogeochemical cycles on Earth, and the outer Solar System.

"Given the important role plankton plays in the Earth's biogeochemical cycles, and for example as a food source for many fish species, the impact that ocean acidification-induced changes in the chemical composition of seawater will have on plankton is a major concern."
Recent studies showed that bamboos are a significant organic silicon pool and play an important role in biogeochemical cycles of silicon and other nutrients because of their special growth habit and biogeochemical characteristics, i.e., rapid biomass accumulation, the extremely high biomass of fine roots, and the extremely high silicon content (Christanty et al., 1997; Mailly et al., 1997; Li et al., 2006; Ding et al., 2008).
Earth and space sciences includes concepts related to objects in the universe, the history of the Earth, properties of Earth materials, tectonics, energy in Earth systems, climate and weather, and biogeochemical cycles. The 2009 science assessment was composed of 143 questions at grade 4, 162 at grade 8, and 179 at grade 12.
