On the relative roles of hydrology, salinity, temperature, and root productivity in controlling soil respiration from coastal swamps (freshwater)
Ken W. Krauss, Julie L. Whitbeck, Rebecca J. Howard
2012, Plant and Soil (358) 265-274
Background and aims Soil CO2 emissions can dominate gaseous carbon losses from forested wetlands (swamps), especially those positioned in coastal environments. Understanding the varied roles of hydroperiod, salinity, temperature, and root productivity on soil respiration is important in discerning how carbon balances may shift as freshwater swamps retreat inland with...

Susan K. Skagen, Paul A. Smith, Brad A. Andres, Garry Donaldson, Stephen Brown
2012, Book chapter, Arctic shorebirds in North America: a decade of monitoring
Long-term monitoring of populations is of paramount importance to understanding responses oforganisms to global environmental change and to evaluating whether conservation practices are yielding intended results through time (Wiens 2009). The population status of many shorebird species, the focus of this volume, remain poorly known. Long-distance migrant shorebirds have proven...
Problem of the Love‐Gannon relation between the asymmetric disturbance field and Dst
G. L. Siscoe, Jeffrey J. Love, J.L. Gannon
2012, Journal of Geophysical Research A: Space Physics (117)
Love and Gannon (2009) discovered that statistically, over a fifty year period the difference in the dawn and dusk disturbance‐field H component at low latitudes (hourly averaged) is linearly proportional to Dst. If the difference is designated by δDD in units of nT/RE, then the Love‐Gannon (L‐G) relation is δDD = −0.2 Dst. At any time departures from the relation can...
Review and update of the applications of organic petrology: Part 1, geological applications
Isabel Suarez-Ruiz, Deolinda Flores, João Graciano Mendonça Filho, Paul C. Hackley
2012, International Journal of Coal Geology (99) 54-112
Organic petrology developed as coal petrology at the beginning of the 20th century dedicated mainly to the study of coals because of their utilization in industry. Coal petrology was then considered a branch of coal science. Later, with the development of specialized nomenclature, classification of coal components, and the standardization...
