Reconstruction of the Central Zagros paleo climate and paleo environment
Introduction The study of lake sediments has been widely used in recent decades to identify past climate and environmental changes. Lake basins have significant spatial and temporal patterns and provide valuable evidences of physical and chemical changes. However, in general, the climate of the Holocene period has been more stable and uniform than previous glacial and interglacial periods. How...
متن کاملPaleo-perspectives on ocean acidification.
The anthropogenic rise in atmospheric CO(2) is driving fundamental and unprecedented changes in the chemistry of the oceans. This has led to changes in the physiology of a wide variety of marine organisms and, consequently, the ecology of the ocean. This review explores recent advances in our understanding of ocean acidification with a particular emphasis on past changes to ocean chemistry and ...
متن کاملThe Paleo diet and diabetes.
151 T and defects in insulin secretion. Obesity is the major risk factor for the development of the condition and a number of studies— including the Diabetes Prevention Program, the Da Qing IGT and Diabetes Study, and the Finnish Diabetes Prevention Study— have shown that lifestyle modification (diet and exercise) can significantly prevent the progression of glucose intolerance (prediabetes) to...
متن کاملPaleo-Green Revolution for rice.
A central element of the Green Revolution was the widespread adoption of semidwarf rice cultivars (SRCs) that more than doubled worldwide rice production (1). The high-yield potentials of modern SRCs are attributed primarily to their improved harvest index, lodging resistance, and responsiveness to high inputs (primarily nitrogen and water) (1–3), contributing to their adoption in irrigated are...
متن کاملCarbon isotope compositions of terrestrial C3 plants as indicators of (paleo)ecology and (paleo)climate.
A broad compilation of modern carbon isotope compositions in all C3 plant types shows a monotonic increase in δ(13)C with decreasing mean annual precipitation (MAP) that differs from previous models. Corrections for temperature, altitude, or latitude are smaller than previously estimated. As corrected for altitude, latitude, and the δ(13)C of atmospheric CO(2), these data permit refined interpr...
