The basic objective of this investigation was to identify and to
examine factors determining the volume of imports of inshell and shelled
Brazil nuts in major importing countries: the United States, the
Federal Republic of Germany and the United Kingdom.
The approach followed involved the construction and analysis of
an...
Population growth is affected by several factors such as climate, species interaction
and harvesting pressure. However, additional complexity can arise if fishing increases the sensitivity
to environmental variability. To predict the effects of fisheries and climate on marine populations,
there is a need for improved understanding of how they affect...
An interlaboratory study of Mg/Ca and Sr/Ca ratios in three commercially available carbonate reference
materials (BAM RS3, CMSI 1767, and ECRM 752-1) was performed with the participation of
25 laboratories that determine foraminiferal Mg/Ca ratios worldwide. These reference materials containing
Mg/Ca in the range of foraminiferal calcite (0.8 mmol/mol to...
Headwater streams and wetlands are integral components of watersheds that are critical for biodiversity, fisheries, ecosystem functions, natural resource-based economies, and human society and culture. These and other ecosystem services provided by intact and clean headwater streams and wetlands are critical for a sustainable future. Loss of legal protections for...
In this technical note, a steady-state analytical solution of concentrations of a parent solute reacting to a daughter solute, both of which are undergoing transport and multirate mass transfer, is presented. Although the governing equations are complicated, the resulting solution can be expressed in simple terms. A function of the...
Metabolomics is a comprehensive analysis of small molecules, or metabolites, in a system. Metabolomics is a hypothesis-generating experiment and offers an unbiased analysis of cell metabolism that can aid in the understanding of fundamental biological processes. Metabolomics is widely and broadly applicable in the biological sciences and has been used...
The purpose of this study is to determine factors that encourage second
generation Latina/os to obtain a community college education. A critical qualitative
ethnography focused on "Testimonio" was used in conducting this study. The key
findings were formulated around three critical research questions. In relation to each
research question, three...
Chinook salmon (Oncorhynchus tshawytscha) display the greatest variability of return times to freshwater of all Pacific salmon. Differential return times to freshwater have segregated populations of Chinook into two broad types or runs, fall and spring, named for the time of year in which they migrate to freshwater. Migration time...
Marine Eco-Label Japan (MEL) is a unique Japanese seafood eco-labeling scheme launched in Japan shortly after the Marine Stewardship Council (MSC) opened its office to evaluate the management of Japanese fisheries resources by large-scale commercial fisheries and small-scale and diverse fishing gear. It became MEL ver. 2 and was approved...
We apply GENMOM, a coupled atmosphere–ocean climate model, to simulate eight equilibrium time
slices at 3000-year intervals for the past 21,000 years forced
by changes in Earth–Sun geometry, atmospheric greenhouse
gases (GHGs), continental ice sheets, and sea level. Simulated
global cooling during the Last Glacial Maximum
(LGM) is 3.8°C and...
