Contrasting patterns of taxonomic, phylogenetic and functional variation along a Costa Rican altitudinal gradient in the plant family Melastomataceae

Abstract: The functional composition of plant communities in montane regions has been studied for decades, and most recent analyses find that environmentally favourable landscapes at lower altitudes tend to be dominated by species with resource-acquisitive traits, while more resource-conservative taxa dominate higher-altitude communities. However, it is unclear the extent to which this pattern is driven by co-gradient variation within clades or changes in clade representation across the gradient. To test for co-gradient variation, species composition, phylogenetic structure and functional traits were quantified for 97 species within the plant family Melastomataceae at five locations across a 2500-m altitudinal gradient along Volcan Barva in Costa Rica. Average melastome leaf force to punch, specific leaf area and leaf size vary with altitude, while four other functional traits do not. Taxonomic dissimilarity between communities was correlated with altitudinal difference, while phylogenetic dissimilarity was correlated with altitudinal dissimilarity only when measured with a metric that emphasizes shallow turnover of the tips of the phylogeny. These results highlight how species turnover may be more pronounced than functional or phylogenetic variation along altitudinal gradients. In addition, these results highlight the conservation value of lowland tropical forests, which here harbour a disproportionate amount of phylogenetic and functional diversity.

Ballistic mobility degradation in scaled-down channel of a MOSFET

Abstract: The ballistic mobility data by Luskawoski et. al [1] is interpreted by using recently published formalism [2]. The mobility is shown to be ballistic when the ballistic mean free path in a nanoscale transistor exceeds the channel length. This ballistic mobility affects the critical voltage V c that can be as low as the thermal voltage 2 V t (0.0518 V at room temperature) for a quasi-2-domensional (Q2D) nanostructure at the onset of nonlinearity in current-voltage relationship. The applied voltage V=0.08 V is higher than the thermal voltage triggering decline of mobility at low channel lengths due to high fields present. The general formalism is in excellent agreement with the experimental data.

The Impact of an Emerging Technology on the Early Buyer-Seller Relationship

Abstract: The purpose of this study is to generate propositions about the developing business-to-business buyer-seller relationship in an emerging technology market. The role of the technology buyer and seller at an evaluative, exploration phase of their nascent relationship has been explored. A conceptual framework of the exploration phase has been developed with descriptive constructs. The study’s methodology focuses on a multiple-site field study of buyer and seller organizations in the health care field. The study results in propositions and new theoretical insights into early relationship development when an emerging technology is present in the marketplace.
