The Late Archean Biospheric Explosion
biogenic platform carbonates [4]. By c.2.45 Ga oxygen levels had begun to rise in the Earth’s atmosphere setting the stage for the evolution of the modern biosphere. Here we focus on concretionary structures, which can act as sensitive barometers of biological activity, to provide us with potential insights into the expansion of this early biosphere prior to the first appearance of oxygen in th...
متن کاملLate Archean biospheric oxygenation and atmospheric evolution.
High-resolution geochemical analyses of organic-rich shale and carbonate through the 2500 million-year-old Mount McRae Shale in the Hamersley Basin of northwestern Australia record changes in both the oxidation state of the surface ocean and the atmospheric composition. The Mount McRae record of sulfur isotopes captures the widespread and possibly permanent activation of the oxidative sulfur cy...
متن کامل16 Temperature , Biogenesis , and Biospheric Self - Organization
We argue that the biosphere has evolved deterministically as a selforganized system, given the initial conditions of the Sun-Earth system. With temperature as a critical constraint, biogenesis and the overall patterns of biotic evolution were the highly probable outcomes of this deterministic process. Emergence of life and its major evolutionary innovations occurred as soon as the temperature d...
متن کاملBiospheric primary production during an ENSO transition.
The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) provides global monthly measurements of both oceanic phytoplankton chlorophyll biomass and light harvesting by land plants. These measurements allowed the comparison of simultaneous ocean and land net primary production (NPP) responses to a major El Niño to La Niña transition. Between September 1997 and August 2000, biospheric NPP varied by 6 ...
متن کاملMental contrasting and transfer of energization.
Mental contrasting a desired future with present reality is a self-regulation strategy that fosters energization in line with a person's expectations of successfully attaining the desired future. We investigated whether physiological energization (measured by systolic blood pressure) elicited by mental contrasting a desired future of solving a given task transfers to effort in an unrelated task...
