The purpose of this investigation was to determine the nature of the
chemical constituents of incense cedar bark with the hope that such an endeavor
would spur future research, development and use of a now neglected
natural raw material.
The bark from nine trees, which were separated into three age...
ABSTRACT
Eukaryotes produce functionally diverse classes of
small RNAs (20–25 nt). These include microRNAs
(miRNAs), which act as regulatory factors during
growth and development, and short-interfering
RNAs (siRNAs), which function in several epigenetic
and post-transcriptional silencing systems. The
Arabidopsis Small RNA Project (ASRP) seeks to characterize
and functionally analyze the...
Ecological restoration programs often attempt to maintain or enhance ecosystem services (ES), but fine-scale maps of multiple ES are rarely available to support prioritization among potential projects. Here we use agency reports, citizen science, and social media as data sources to quantify the spatial distribution of five recreational elements of...
The origin of the late pre-industrial Holocene (LPIH) increase in atmospheric methane concentrations has been much debated. Hypotheses invoking changes in solely anthropogenic sources or solely natural sources have been proposed to explain the increase in concentrations. Here two high-resolution, high-precision ice core methane concentration records from Greenland and Antarctica...
