The mouse ornithine decarboxylase gene is part of a dispersed family of at least 14 related loci (1.2). Eight Odc loci have been assigned to 7 different autosomes (3,4), although the actual structural locus has not been identified. Recent mapping of the mouse genome has exploited the sequence diversity apparent between inbred strains and feral species, notably Mus spretus (5). This diversity, e...

Previously we demonstrated a method, Quantized Surface Complementarity Diversity (QSCD), of defining molecular diversity by measuring shape and functional complementarity of molecules to a basis set of theoretical target surfaces [Wintner E.A. and Moallemi C.C., J. Med. Chem., 43 (2000) 1993]. In this paper we demonstrate a method of mapping actual protein pockets to the same basis set of theor...

Concept mapping is one of the most intimate and most dynamic learning support activities that needs still a drastic further evolution of methods and tools. WWW-based concept mapping gains momentum quite fast now and needs a solid reviewing of the various approaches and the empirical effects. This article bridges the technological advance of WWW-based concept mapping tools and its more recent ef...

Describing the genetic diversity in the gene pool of crops will provide breeders with novel resources for varietal improvement. Nested Association Mapping (NAM) populations are uniquely suited for characterizing parental diversity through the shuffling and fixation of parental haplotypes. Here, we describe a set of 1879 rice NAM lines created through the selfing and single-seed descent of F1 hy...

We aimed to identify regional centres of plant biodiversity in South Australia, a sub-continental land area of 983,482 km2, by mapping a suite of metrics. Broad-brush conservation issues associated with the centres were mapped, specifically climate sensitivity, exposure to habitat fragmentation, introduced species and altered fire regimes. We compiled 727,417 plant species records from plot-bas...

INTRODuCTION Genetic markers provide information about allelic variation at a given locus. The increasing availability of molecular markers in farm animals allows the detailed analyses and evaluation of genetic diversity and furthermore the detection of genes influencing economically important traits. The majority of molecular markers used nowadays with high-throughput systems are microsatellit...

Airborne remote sensing has an important role to play in mapping and monitoring biodiversity over large spatial scales. Techniques for applying this technology to biodiversity mapping have focused on remote species identification of individual crowns; however, this requires collection of a large number of crowns to train a classifier, which may limit the usefulness of this approach in many stud...

With the development of information technology today is the nature of today's information is also experiencing growth. These developments encourage a more dynamic source of information, autonomy, variety and large. Diversity occurs not only at the technical level but also at the level of representation of information. This difference can occur at syntactic, schematic and semantic level. This di...

A major goal of evolutionary biology is to identify the genotypes and phenotypes that underlie adaptation to divergent environments. Stickleback fish, including the threespine stickleback (Gasterosteus aculeatus) and the ninespine stickleback (Pungitius pungitius), have been at the forefront of research to uncover the genetic and molecular architecture that underlies phenotypic diversity and ad...

The increasing availability of molecular markers in farm animals allows the detailed analyses and evaluation of genetic diversity and also, the detection of genes influencing economically important traits.
