Chrysobothris mali Horn and C. femorata Olivier (Coleoptera : Buprestidae) are two flatheaded wood boring beetle species that have become economically impactful pests in North American high value tree cropping systems. Both species are native to North America, with C. femorata occurring across the continent (Wellso and Manley 2007), whereas...
A regional analysis of the street tree problem has been undertaken in order to evolve a system of tree classification

Low copy number anonymous nuclear loci were used to search for species markers in four species of Klamath Basin suckers. We sequenced 28 randomly chosen loci representing 10,421 bp; 21 loci were similar to sequences in GenBank. Eight fixed sequence differences were found among Klamath species. Locus 120 contained rare...

Economic development of coastal and regional economies will benefit from new approaches to maximizing benefits from harvested products that include...
