Modelling allometric equations for saplings of hybrid poplar clone produce a highly accurate estimate of pure productivity and C sequestration, leading to better sales and determination of the capacity of cellulose resources and bio-energy pools. Twenty five cuttings with 25 cm length were planted within a 1×1 m2 area in the Talookola nursery, Sari, in 2011. Ten saplings were selected from the ...

The growth of Brycinus longipinnis caught at Aghien Lagoon was studied between June 2014 and May 2015 through type, condition factor parameters according to the Von Bertalanffy model. Sampling conducted using experimental fisheries. Growth type determined from length-weight relationship model FiSAT software. negative allometric (b = 2.59). population grows faster towards asymptotic length ((L∞ ...

Understanding the concept of extrapolation of dose between species is important for pharmaceutical researchers when initiating new animal or human experiments. Interspecies allometric scaling for dose conversion from animal to human studies is one of the most controversial areas in clinical pharmacology. Allometric approach considers the differences in body surface area, which is associated wit...

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...

Allometric growth pattern and body shape changes of the Green terror (Andinoacara rivulatus)(Cichlidae) were studied using landmark-based geometric morphometric (GM) and traditional methods, from hatching up to 1266 Hours Post Hatching (HPH) under culture conditions. The left side of specimens were photographed using digital camera and morphometric characters, including total length, head lengt...

Purpose: Allometry is a method to express the relationship between physiological and anatomical variables. It can be used to measure the vital capacity through mathematical equations. This study aimed at evaluating lung function indices to estimate the maximal aerobic power by respiratory gas analysis device and the allometric equation. Methods: This study was a descriptive and correlational r...

The astounding variety of angiosperm flower morphologies has evolved in response to many selective forces. Flower development is highly coordinated and involves developmental associations between size and shape, ontogenetic allometry, which in turn affect the morphology of mature flowers. Although ontogenetic allometries can act as a developmental constraint and may influence adaptive evolution...

Bogue ( Boops boops , Linnaeus, 1758) that was gathered in Antalya Bay had their ages, growth rates, and mortality examined. Using the von Bertalanffy equation, L t = 37.50 (1 - e -0.15(t + 1.32) ) (R 2 0.988), length expressed for entire sample without revealing any disparities between sexes. The values of allometric coefficient b length-weight relationships specify negative (b < 3) females...
