TL;DR: In this paper, a multivariate factor analysis was used to identify the common axes (or dimensions) of pattern and structure which were measured by a reduced set of 26 metrics, which were interpreted as composite measures of average patch compaction, overall image texture, average patch shape, patch perimeter-area scaling, number of attribute classes, and large-patch density area scaling.

TL;DR: In this article, the scale problems involved in reporting landscape pattern for a large, heterogeneous region were examined and it was shown that the indices are sensi- tive to the calculation scale, i.e., the unit area or extent over which the index is computed.

TL;DR: Ethical stewardship of the environment requires that society monitor and assess environmental changes at the national scale with a view toward the conservation and wise management of the authors' natural resources.

TL;DR: A progress report of the Collaborative Cross breeding program at ORNL is presented and a description of the kinds of investigations that this resource will support is presented.

TL;DR: Phenotypic variation in the CC breeding population exceeds that of existing mouse genetic reference populations due to both high founder genetic diversity and novel epistatic combinations, however, some focal evidence of allele purging was detected including a suggestive QTL for litter size in a location of changing allele frequency.
