Evidence disproving tropical ‘thermostat’ theory:global warming can breach limits for life
disproving tropical thermostat theory global warming breach limits for life
2017/3/14
New research findings show that as the world warmed millions of years ago, conditions in the tropics may have made it so hot some organisms couldn’t survive.Longstanding theories dating to the 1980s s...
On a tropical island, fossils reveal the past – and possible future – of polar ice
On a tropical island, fossils reveal the past possible future polar ice
2015/1/20
The balmy islands of Seychelles couldn’t feel farther from Antarctica, but their fossil corals could reveal much about the fate of polar ice sheets.About 125,000 years ago, the average global temperat...
Oxygen isotopes as a valuable tool for measuring annual growth in tropical trees that lack distinct annual rings
tropical tree with non-distinct annual rings cellulose oxygen isotopes fractionation model Styrax tonkinensis Ficus semicordata var. semicordata
2017/4/11
Some trees from tropical areas lack visually detectable and consistent annual growth rings. As such, we have measured
the radial variation of cellulose oxygen isotopes in trees that grow in seasonall...
Distribution of combined monosaccharides in sediments from the Lake Rawa Danau, West Java, Indonesia: Sources and diagenetic fate of carbohydrates in a tropical wetland
biomarker diagenesis wetland vegetation changes
2017/4/12
Monosaccharide compositions were determined for a sediment core (RD-1) collected from a tropical wetland, Rawa
Danau, West Java, Indonesia (location 6°11′ S and 105°59′ E) to assess the sources and d...
The biogeochemistry of tropical lakes: A case study from Lake Matano, Indonesia
The biogeochemistry of tropical lakes A case study Lake Matano Indonesia
2014/4/18
We examined the chemical composition of the water column of Lake Matano, Sulawesi Island, Indonesia, to document how the high abundances of Fe (hydr)oxides in tropical soils and minimal seasonal tempe...
Submicroscopic Structure of Fe-Coatings on Quartz Grains in Tropical Environments
Electron Microscopy Fe-coating Fe-nodules Fe-oxide Forms Submicroscopic Structure Ultrathin Sections X-ray Microprobe Analysis
2011/12/27
Formation of Fe-coatings or segregation at the expense of quartz grains is a common process in the tropical environment. Limited information is available about their internal structure at the submicro...
