Abstract:
Abstract Restriction fragment length polymorphisms were used to distinguish genotypes of two species of Populus, P. fremontii ('Fremont') and P. angustifolia ('narrowleaf'). Both inter- and intraspecific polymorphisms were detected in these cottonwood trees. The interspecific variation was much greater than the intraspecific variation. This permitted identification of parental genotypes within individual trees of a hybrid swarm which exists in an overlap zone between the two species. Within this hybrid swarm, individual trees are either F1 hybrids or backcrosses with a pure 'narrowleaf' parent

Abstract:
A rootstock comparison trial for almond was planted in sandy soil near Atwater, Calif., in Feb.1989. The study consisted of five replications of five trees each for six rootstocks, each with two cultivars. The rootstocks were `Nemaguard' peach, `Nemared' peach, `Hansen 536' peach × almond hybrid, `'Bright's hybrid' (peach × almond), `Halford' peach seedling, and `Lovell' peach seedling. Two cultivars, `Nonpareil' and `Carmel', were used with each rootstock. The accumulated kernel production from `Nonpareil' through the 1998 harvest was highest for trees on `Hansen 536', second highest for thos

Abstract:
Parkerella populi Funk was found for the first time in the United States on hybrid aspen in two test plantings in Wisconsin. Parkerella populi was associated only with declining trees of a triploid Populus tremuloides Michx. × P. tremula L. hybrid. Parkerella populi was the only fungus found associated with deeply fissured, black bark of the declining trees. Adjacent trees of different clones were not affected in either plantation. These observations suggest, therefore, that P. populi may have been a primary pathogen of these hybrids.

Work from the 1970s indicated that, relative to either parent species, crosses between red spruce (Picea rubens Sarg.) and black spruce (Picea mariana (Mill.) B.S.P.) were inferior with respect to both growth and photosynthesis. We re-examined the hypothesis that there is negative heterosis in hybrids of red and black spruce using 22-year-old trees in a common garden study planted on two sites. The trees were the product of controlled crossings and represent a continuum from hybrid class 0 (pure black spruce) to hybrid class 1 (pure red spruce). Progeny of all controlled crosses were measured

AbstractCrossability of Pinus sibirica and P. pumila hybrids and their parental species was studied using the controlled pollination method.

In the case of P. pumila, trees were pollinated in a wild stand located in the Upper Angara River delta. Parental species had the highest number of filled seeds under open pollination.

Abstract:
It has become well known that an evolutionary tree is inadequate to represent fully the history of life. Two possible ways of dealing with this are the rooted subtree prune and regraft distance between a pair of trees, which measures how different they are, and the slightly more biologically sound hybridisation number of a set of trees that attempts to determine the minimum number of hybrid events that must have occurred for a given set of evolutionary trees. When characterised via agreement forests both problems are, although NP hard, fixed parameter tractable---meaning the problem can be con

Abstract:
Coal has been and will continue to be an important energy source in the U.S. for the foreseeable future. Surface mining for coal is one of the methods employed to extract this resource from below the ground. The process of surface mining removes native topsoils and any native vegetation that was support by these native soils. In the Appalachian coal-producing region of the United States, the pre-mining landscape is predominantly forested. Prior to the Surface Mining and Reclamation Act of 1977 (SMCRA), surface mined lands were commonly reclaimed to forests. Subsequent to the passage of SM

Transactional memory (TM) has emerged as a promising synchronization abstraction for multi-core architectures. Unlike traditional lock-based approaches, TM shifts the burden of implementing threads synchronization from the programmer to an underlying framework using hardware (HTM) and/or software (STM) components. Although TM can be leveraged to implement transactional data structures (i.e., those where multiple operations are allowed to execute atomically, all-or-nothing, according to the transaction paradigm), its intensive speculation may result in significantly lower performance than the

The proposed heuristic uses a genetic algorithm to manipulate spanning trees, which are then transformed into Steiner trees by inserting and repositioning the Steiner points.
