the study was conducted to investigate the effect of humic acid on the germination properties of medicinal plants borago officinalis and cichorium intybus in a completely randomized design with five replications. experimental treatment comprised the following dosages 0, 15, and 30 g l-1. the results revealed that effect of humic acid on the germination properties of c. intybus was significant (p

In this study, allometric trajectories for 51 rodent species, comprising equal representatives from each of the major clades (Ctenohystrica, Muroidea, Sciuridae), are compared in a multivariate morphospace (=allometric space) to quantify magnitudes of disparity in cranial growth. Variability in allometric trajectory patterns was compared to measures of adult disparity in each clade, and dietary...

Variability of taurine (2-aminoethane sulfonic acid) was studied as a function of size in the mussel Mytilus galloprovincialis and tissue specificity. Isometric and/or allometric relationships were established with regard to total soft mass of the mussels between 20 and 60 mm shell length. Relative amounts of taurine dropped significantly with increasing mass of whole soft tissues with an allom...

Extensive studies of vertebrates have shown that brain size scales to body size following power law functions. Most animals are substantially smaller than vertebrates, and extremely small animals face significant challenges relating to nervous system design and function, yet little is known about their brain allometry. Within a well-defined monophyletic taxon, Formicidae (ants), we analyzed how...

this research develops an allometric model for estimation of biomass based on the height and dbh of trees in the hyrcanian forests of iran. an accurate allometric model reduces the uncertainty of allometric equation in biomass estimation using radar images. in this study, 317 trees were selected randomly from the 4 different dominant tree species for the development of an allometric model cover...

Length weight relationship and other allometric relationships were studied for shortneck clam Paphia malabarica. Lengthweight and total weight-flesh weight relationship in males and females were significantly different (p <0.01). The rate of growth in all other relationship studied were not significantly different between sexes. In lengthweight relationship it showed isometric growth and in len...
