Isozyme Studies of Bark Beetle Population Genetics and Systematics1
Electrophoretic analysis was used extensively in the 1970's to estimate genetic relationships among populations, species, and closely related genera of many different plants and animals, including many insect groups. Some of the first electrophoretic work on bark beetles was done by Anderson and others (1979), Anderson and others (1983), Florence and Kulhavy (1981), Florence and others (1982), ...
متن کاملIsozyme markers associated with O(3) tolerance indicate shift in genetic structure of ponderosa and Jeffrey pine in Sequoia National Park, California.
Effects of canopy ozone (O(3)) exposure and signatures of genetic structure using isozyme markers associated with O(3) tolerance were analyzed in approximately 20-, approximately 80-, and >200-yr-old ponderosa (Pinus ponderosa Dougl. ex Laws.) and Jeffrey pine (Pinus jeffreyi Grev. & Balf.) in Sequoia National Park, California. For both species, the number of alleles and genotypes per loci was ...
متن کاملLate Holocene expansion of ponderosa pine (Pinus ponderosa) in the Central Rocky Mountains, USA
Aim Ponderosa pine (Pinus ponderosa) experienced one of the most extensive and rapid post-glacial plant migrations in western North America. We used plant macrofossils from woodrat (Neotoma) middens to reconstruct its spread in the Central Rocky Mountains, identify other vegetation changes coinciding with P. ponderosa expansion at the same sites, and relate P. ponderosa migra-tional history to ...
متن کاملVariable Chemistry and Herbivory of Ponderosa Pine Cones
We measured the terpenoid chemistry, cone insect distribution, and the relationship between these two parameters in the seed cones of ponderosa pine. Analyses of mono-, sesqui-, and diterpenes from four separate sites revealed high amounts of terpenoid diversity and variation. The majority of this variation occurred among trees within sites, but differences were also seen among sites and among ...
متن کاملFrequencies of null alleles at enzyme Loci in natural populations of ponderosa and red pine.
Pinus ponderosa and P. resinosa population samples have mean frequencies of enzymatically inactive alleles of 0.0031 and 0.0028 at 29 and 27 enzyme loci, respectively. Such alleles are rare and are apparently maintained by selection-mutation balance. Ponderosa pine have much higher amounts of allozymic and polygenic phenotypic variation than red pine, yet both species have similar frequencies o...
