We tested the release potential of suppressed giant sequoia (Sequoiadendron giganteum) saplings in a plantation that was overgrown with shrubs at Blodgett Forest Research Station, CA in the mixed conifer forest of the Sierra Nevada. As an ancillary case study, we compared the shrub removal method of release with a clear-and-plant method in an adjacent stand. Measurements of various morphologica...

We describe watershed-scale habitat associations of three Cantharellus species with respect to stand age. During the 1998 autumn fruiting season we collected chanterelle sporocarps from 18 forest stands in and adjacent to the H.J. Andrews experimental forest in the central Cascade Mountains of Oregon. Sampled stands represented two age categories: old growth ( approximately 350+ y) and 40-60-y-...

To test the hypothesis that eastern red cedar (Juniperus virginiana L.) is allelopathic, seedling establishment of five herbaceous prairie species was evaluated by growing seeds in soil collected beneath and adjacent to a stand ofthis tree species. While four species showed no significant effect, the gennination of one species, finger coreopsis (Coreopsis pa/mata Nutt.), was significantly reduc...

A set S ⊆ V (G) is independent if no two vertices from S are adjacent. Let α (G) stand for the cardinality of a largest independent set. In this paper we prove that if Λ is a nonempty collection of maximum independent sets of a graph G, and S is an independent set, then • there is a matching from S − ⋂ Λ into ⋃ Λ− S, and • |S|+ α(G) 6 ∣∣∣⋂Λ ∩ S∣∣∣+ ∣∣∣⋃Λ ∪ S∣∣∣. Based on these findings we provi...

in this research with using of obtained information from a natural fraxinus the variation of quantities and qualitative measures of current stand in an 8 year period was conducted in chelir part of kheyroud forest. data collection was conducted by full callipering method in two periods of 1384 and 1392. during the period of study the parameters of dominant mean height and relative crown height ...

Macrobenthos organisms are vital ecological components of intertidal wetlands. This work studied effects non-native mangrove rehabilitation (Kandelia obovata) and salt marsh invasion (Spartina alterniflora) on macrobenthos communities in Ximen Island (Zhejiang, China). The were compared between rehabilitated K. obovata forests five different stand ages (2-, 8-, 11-, 16-, 60-year-old) adjacent S...

We investigate the nature of charge transport in deoxyribonucleic acid (DNA) using self-assembled layers of DNA in large-area molecular junctions. A protocol was developed that yields dense monolayers where the DNA molecules are not standing upright, but are lying flat on the substrate. As a result the charge transport is measured not along the DNA molecules but in the transverse direction, acr...

Humans are capable of pointing to a target with accuracy. However, when vision is distorted through a visual rotation or mirror-reversed vision, the performance is initially degraded and thereafter improves with practice. There are suggestions this gradual improvement results from a sensorimotor recalibration involving initial gating of the somatosensory information from the pointing hand. In t...
