HIGHLIGHTS Ruditapes decussatus from four sites belonging to Monastir bay (Tunisia) was first time analyzed based on morphometry and comparative statistics. The site of Ksiba distinguishable other by larger heavier specimens. sub-trapezoidal shape dominant with small- size classes, in most sites. principal component analysis (PCA) revealed different population groups, two intra-population group...

introduction management principles predominated on the development and evolution stages of the geomorphic landscapes are different. this is because of variability in landscape evolution, its relationship with other system components and its response to environmental changes and feedback. one of the most important methods of management of geomorphic landscape is the study and evaluation of morph...

Author manuscripts have been peer reviewed and accepted for publication but have not yet been edited. In this article we propose new individualized busulfan dosing regimens, in order to increase safety and efficacy during busulfan therapy especially in very small children. Busulfan has a very narrow therapeutic range with higher AUC values causing a high risk of sinuosoidal obstruction syndrome...

we collected silver bream blicca bjoerkna from march to july 2013 from aras dam lake (north-west of iran) and investigated its age, size, and some biological characteristics. the maximum age was 5 + years. the total length and weight of specimens ranged 137-278 mm and 26-247 g for male and 134-282 mm and 26-289 g for female, respectively. length-weight relationship was estimated as w = 1e-06tl ...

The miombo woodland is the most extensive dry forest in the world, with the potential to store substantial amounts of biomass carbon. Efforts to obtain accurate estimates of carbon stocks in the miombo woodlands are limited by a general lack of biomass estimation models (BEMs). This study aimed to evaluate the accuracy of most commonly employed allometric models for estimating aboveground bioma...

Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.) is the most important conifer species for timber production with huge distribution area in southern China. Accurate estimation of biomass is required for accounting and monitoring Chinese forest carbon stocking. In the study, allometric equation W = a(D2H)b was used to analyze tree biomass of Chinese fir. The common methods for estimating allo...

The design of living beings is not only a matter of molecular biology but also of geometry and physics. This was once more demonstrated with a biophysical model by G. B. West et al. (1) that had been fine-tuned to predict the famous scaling law of metabolism (2), namely a 3/4 power relation between body mass and energy consumption. While properties and predictions of the model are remarkable, a...

BACKGROUND Allometric scaling, which represents the dependence of biological traits or processes on body size, is a long-standing subject in biological science. However, there has been no study to consider heat loss to the ambient and an insulation layer representing mammalian skin and fur for the derivation of the scaling law of metabolism. METHODS A simple heat transfer model is proposed to...

Allometric equations are widely used in many branches of biological science. The potential information content of the normalization constant b in allometric equations of the form Y = bX(a) has, however, remained largely neglected. To demonstrate the potential for utilizing this information, I generated a large number of artificial datasets that resembled those that are frequently encountered in...
