The relationship between stable oxygen and hydrogen isotope ratios of water in astomatal plants

Isotropic fractination of leaf water during transpiration is influenced by both equilibrium and kinetic factors. Previous workers have predicted that the influence of each factor varies depending upon the path of water loss,m whether centralized through stomata, or diffuse through the cuticle. We studied the relationship between the δD and δ18O values of lead and stem waters of laurel sumac, Rhu

Quaternary history of some southern and central Rocky Mountain basins

This chapter summarizes the current state of late Cenozoic stratigraphic knowledge in some Rocky Mountain basins (here defined as the structurally low portions of major drainage basins) that have been studied in detail since Scott’s (1965) summary on the nonglacial history of the southern and middle Rocky Mountains. The Quaternary history of few of these basins has been studied as intensively as t

Initiation processes and flow evolution of turbidity currents: Implications for the depositional record

Interpretations of sea-level change and source-area tectonism from the character of turbidite deposits require knowledge of the sediment source, the flow-initiation process, how the turbidity current evolved during flow, and what flow phases were associated with deposition. The flow responds to shape and size characteristics of both the erosional pathway and the morphology of previous deposits; th

Regressive coastal deposits on Quaternary continental shelves: Preservation and legacy

Regressive coastal deposits containing internal downlapping surfaces are common on continental shelves of the world. Through theoretical considerations and evaluation of examples from the literature and our own studies in California and Italy, we have examined the conditions that lead both to the formation and preservation of these deposits.Coastal downlapping deposits form by progradation of coas

A records system for a captive crane flock

Crane record keeping systems have been evolving at the Patuxent Wildlife Research Center (PWRC) since 1966 and at the International Crane Foundation (ICF) since 1974. The system we present here, a hybrid of the two systems, has been reorganized to promote easy access of information and to limit redundancy.
