Secondary forests are more extensive than old-growth forests in many tropical regions, yet the genetic composition of colonizing populations is poorly understood. We analyzed the parentage of a founder population of 130 individuals of the canopy palm Iriartea deltoidea in a 24-year-old second-growth forest in lowland Costa Rica. Among 66 trees in adjacent old-growth forest, only two individuals...

in this study, in vitro growth characteristics of fibroblasts of metacarpal region of horses and caspian miniature horses were evaluated. under general anesthesia and aseptic condition, a full thickness skin incision was created on the lateral aspect of mid-third of left metacarpal region of 4 mixed thoroughbred horses and 4 caspian miniature horses and 3 grams of subcutaneous tissue was harves...

BACKGROUND Accelerated infant growth is a possible explanation for the relation between birth weight and adult diseases. OBJECTIVE The aim of this study was to estimate the heritability of infant growth and to examine whether the genetic contribution changes with increasing or decreasing birth weight and gestational age. DESIGN Growth (change in weight z score) was analyzed in 522 infants f...

To understand how genetic architecture translates between phenotypic levels, we mapped the genetic architecture of growth and defense within the Arabidopsis thaliana Kas × Tsu recombinant inbred line population. We measured plant growth using traditional size measurements and size-corrected growth rates. This population contains genetic variation in both the nuclear and cytoplasmic genomes, all...

Objective: Estimation of genetic parameters for Kleiber ratio (KR) and genetic trends for pre-weaning weights of Arabi sheep has not been previously conducted.Methods: Data and pedigree information were collected at the Khuzestan Ramin Agricultural and Natural Resources University, Animal Science Research Station, located in southwest Iran, from 2001 to 2008. (Co)variance components and corresp...
