Tree differences in primary and secondary growth drive convergent scaling in leaf area to sapwood area across Europe [PDF]

open access: yes, 2018
open28siTrees scale leaf (AL) and xylem (AX) areas to couple leaf transpiration and carbon gain with xylem water transport. Some species are known to acclimate in AL : AX balance in response to climate conditions, but whether trees of different species ...

Allometric growth of protein, amino acids, fat and minerals in slow- and fast-growing young chickens

open access: yesCzech Journal of Animal Science, 2011
Allometric growth of body constituents and apparent efficiency of amino acid and nitrogen retention were examined in slow-growing laying-type cockerels (SG) and in fast-growing male broiler hybrids (FG) during the growth period from hatch to Day 22.

Length-weight relationship and condition factor of two sympatric Rutilus (Rrafinesque, 1820) species from Lake Skadar (Montenegro) [PDF]

open access: yesArchives of Biological Sciences, 2012
Two species from the genus Rutilus (Rafinesque, 1820), R. prespensis and R. albus inhabit Lake Skadar. The conditional factor (K) and length-weight relationships (LWRs) of 165 specimens were studied from January 2008 to January 2009. Based on the LWRs,

Root anatomical traits contribute to deeper rooting of maize under compacted field conditions [PDF]

open access: yes, 2020
© The Author(s) 2020. To better understand the role of root anatomy in regulating plant adaptation to soil mechanical impedance, 12 maize lines were evaluated in two soils with and without compaction treatments under field conditions.

Trophic state of the reservoir influences the allometric coefficient and condition factor of Giant Freshwater Prawn (Macrobrachium rosenbergii) cultured in perennial reservoirs of Sri Lanka

open access: yesDavao Research Journal
Giant Freshwater Prawn (Macrobrachium rosenbergii) is an essential crustacean species in culture-based fisheries of Sri Lanka. Studying the morphometric characteristics and empirical models in fishing and aquaculture is highly beneficial; thus, it is the

Allometric Exponent and Randomness

open access: yes, 2013
An allometric height-mass exponent $\gamma$ gives an approximative power-law relation $ \propto H^\gamma$ between the average mass $$ and the height $H$, for a sample of individuals.

An allometric smoothing function to describe the relation between otolith and somatic growth over the lifespan of walleye pollock (Theragra chalcogramma) [PDF]

open access: yes, 2007
We propose a new equation to describe the relation between otolith length (OL) and somatic length (fork length [FL]) of fish for the entire lifespan of the fish.

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.
