The Great Basin Naturalist

Excerpt from The Great Basin Naturalist, 1963, Vol. 23 The genus Dendroctonus consists of thirteen American species that range throughout the coniferous forests from Guatemala to the northern limits of tree growth in Canada and Alaska, and one Eur asian species that inhabits spruce forests from northern France to Siberia. All species infest coniferous hosts, principally representa tives of the genera Pinus, Picea, Pseudotsuga and Larix, where their aggressiveness has marked them as the greatest tree killers known. Fantastic losses of standing timber resources, conservatively estimated as averaging more than five billion board feet annually, have resulted from epidemics of these insects.

Excerpt from The Great Basin Naturalist, 1977, Vol. 37 In 1972 cormorants nested in four trees on the dike at the Geneva Colony (table Trees 2, 3, and 4 were all being utilized by 1 April, but tree 1 was not used for nesting until about 10 days later (fig. Eighteen nests from the previous year were reused, although some were in very poor condition. One Old nest in tree 1 was not used, although it seemed in good condition. No nests were abandoned. One nest each in trees 2 and 4 were lost when they fell out of the trees during a storm. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from The Great Basin Naturalist, 1980, Vol. 40 Stem xylem water potential (predawn) of conifers along a 10 x 50 m transect from meadow through aspen to conifer was mea sured with a pms pressure bomb (waring and Cleary 1967) on 3 August 1977. At least three different branches of each spruce or fir were measured; these trees were all about 1 m tall. Tree Species population structure along this same transect was assessed by aging stems and estimating their heights. Ages were determined by counting terminal bud scale scars or annual growth rings in xy lem cores. In the latter case, the age at the coring height m) was corrected to total age by adding 5 years for aspen and 20 years for fir or spruce, values based on average number of bud scale scars at that height.

Excerpt from The Great Basin Naturalist, 1999, Vol. 59 Season OF emergence.-muscle power output of insects is severely restricted at low temperatures (josephson 1981, Marden and Kramer Stoneflies are no exception. Even winter-emerging species are sluggish and rarely fly at temperatures near or below freezing (frison 1929, Marden and Kramer In addition, during periods of extreme cold, winter stoneflies seek shelter under rocks, bark, and leaves (frison 1929) and are unlikely to be engaged in dispersal activities. Therefore, we assumed species that emerge in colder months are less likely to successfully disperse. We scored species with September to March emergence as 1, species that emerge from April to June as 2, and those that emerge from July to August as 3.

Excerpt from The Great Basin Naturalist, Vol. 26: September 15, 1966 Collections were made mostly by insect net sweeping, vigorously Shaking the plant into the Open net, picking organisms by hand from the plant, or severely beating larger bushes or trees while a net was held beneath the lant. Some collections were made by use of ultra violet and incan escent light sources in specially-designed traps. They were so designed that individual Specimens of species could be taken separately. Such collections were made in plant communities greatly predominated by one or two plant species. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
