Lisianthus (Eustoma grandiflorum) is a cut flower grown due to the wide diversity of colors and longevity in post-harvest. The leaf area measurement fundamental plants because leaves are directly related several processes such as transpiration, radiation interception CO2 fixation that enable plant grow. objective work was determine an allometric equation for estimating lisianthus from linear di...

study of phenotypic diversity among populations can help better understanding of diversification of species within ecosystems and intraspecific diversification in fishes. a geometric morphometric study was carried out using the elliptic fourier analysis to demonstrate the effect of habitat type on morphological features of shemaya ( alburnus chalcoides ) populations. populations were sampled fr...

A general theory of allometric scaling that predicts how the proportions of vascular plants and the characteristics of plant communities change or scale with plant size is outlined. The theory rests, in part, on the assumptions of (1) minimal energy dissipation in the transport of fluid through space-filling, fractal-like, branching vascular networks; and (2) the absence of scaling with plant s...

The multivariate allometric growth patterns from longitudinal data of leg and rostral segments of all instars of Belostoma elegans (Mayr) and B. cummingsi De Carlo are presented for the first time, and the allometric coefficients are compared. The segments of the middle and hind legs present allometric coefficients with opposite polarity to those of forelegs. This discrepancy in the ontogenetic...

[1] Spatially-distributed forest biomass components are essential to understand carbon cycle and the impact of biomass burning emissions on air quality. We estimated the density of forest biomass components (foliage biomass, branch biomass, and aboveground biomass) at a spatial resolution of 1 km across the Contiguous United States using foliage-based generalized allometric models and Moderate-...

The objective of this research was to study variations in allometry of body characters in females and males of two populations of blow flies, Chrysomya albiceps (Wiedemann) (Diptera: Calliphoridae), under different environmental conditions to establish patterns of morphological variation. Body size of both males and females in the experimental population was significantly higher than in the ind...

Allometric scaling is an important universal property of metabolic living systems. It also describes the self-similar branching tree-liked structures in transportation networks. This paper presented a new approach to calculate the allometric scaling power law relations for arbitrary flow networks. This method can not only avoid the shortcoming of losing lots of information in the process of gen...

Submitted: Nov 23, 2012; Accepted: Jan 5, 2013; Published: Aug 5, 2013 Abstract: Allometric analysis of the total body clearance (Cl ), steady-state volume of distribution (V ) and B ss elimination half-life (t ) based on the literature data in fish species was performed for oxolinic acid, flumequine, 1/2 enrofloxacin. Values of Cl and V show allometric dependence on body weight but values of t...

Allometry is an important factor of morphological integration that contributes to the organization of the phenotype and its variation. Variation in the allometric shape of the mandible is particularly important in hominid evolution because the mandible carries important taxonomic traits. Some of these traits are known to covary with size, particularly the retromolar space, symphyseal curvature,...

BACKGROUND AND AIMS Plant biomass-density relationships during self-thinning are determined mainly by allometry. Both allometry and biomass-density relationship have been shown to vary with abiotic conditions, but the effects of biotic interactions have not been investigated. Arbuscular mycorrhizal fungi (AMF) can promote plant growth and affect plant form. Here experiments were carried out to ...
