Ecosystems are highly heterogeneous systems subjected to important levels of environmental variability; however, it is common in terrestrial biogeochemical models to assume homogeneous properties of the elements of the system or constant environmental conditions. For some processes, heterogeneity in these models is treated very simplistically, but there is not much...
Despite the importance of tropical forest ecosystems in the global carbon cycle, there have been few studies of carbon dynamics in this biome. The magnitude of carbon stocks in the tropics and their changes over time are poorly known since ground-based observations are lacking. In this study, total carbon stocks...
Seed-Lab, is a software system for managing seed laboratory information. It was developed at the Oregon State University Seed Testing Laboratory. Seed-Lab was built around a database development package Revelation, which provides its own programming language.
Seed-Lab shields the user from the complexities of database management by supporting menu driven...
There is no information available on water management of birdsfoot
trefoil grown for seed. Information is also not available describing how to
minimize seed losses due to shattering in order to obtain consistently high
birdsfoot trefoil seed yields. The objectives of this research are to: (i) quantify
crop water use,...
Gravity and magnetic data from cruises by the R/V Yaquina in 1973
and the R/V Wecoma in 1975 provide new data that make possible the construction of a map of the free-air gravity anomalies at sea and simple
Bouguer anomalies on lano in Panama, western Colombia, and the eastern
Panama...
When sulfur dioxide is used in commercial drying of fruits in
combination with low storage temperatures, browning and microbial spoilage
can be inhibited. However, the relationship between moisture level,
storage temperature, and sulfur dioxide content on the color of dried
fruit is not known; therefore the purpose of this research...
