Changes in oak (Quercus robur) photosynthesis after winter moth (Operophtera brumata) herbivory are not explained by changes in chemical or structural leaf traits [PDF]

, 2020
Insect herbivores have the potential to change both physical and chemical traits of their host plant. Although the impacts of herbivores on their hosts have been widely studied, experiments assessing changes in multiple leaf traits or functions ...

Evolution and the Growth Process: Natural Selection of Entrepreneurial Traits [PDF]

SSRN Electronic Journal, 2011
This research suggests that a Darwinian evolution of entrepreneurial spirit played a significant role in the process of economic development and the dynamics of inequality within and across societies. The study argues that entrepreneurial spirit evolved non-monotonically in the course of human history.

Ecophysiological traits of grasses: resolving the effects of photosynthetic pathway and phylogeny [PDF]

, 2009
C4 photosynthesis is an important example of convergent evolution in plants, having arisen in eudicots, monocots and diatoms. Comparisons between such diverse groups are confounded by phylogenetic and ecological differences, so that only broad ...

Genotype–environment interactions for growth and carcass traits in different pig breeds kept under conventional and organic production systems

Animal, 2010
The demand for special breeding programmes for organic pig meat production is based on the assumption that pigs kept under organic conditions need different biological properties compared with conventionally kept pigs in order to achieve a good ...

Genetic association of growth traits with carcass and meat traits in Nellore cattle

Genetics and Molecular Research, 2015
The aim of this study was to estimate genetic and phenotypic associations of growth traits with carcass and meat traits in Nellore cattle. Data from male and female animals were used for weaning weight (WW; N = 241,416), yearling weight (YW, N = 126,596), weight gain from weaning to yearling (GWY, N = 78,687), and yearling hip height (YHH, N = 90,720),

Meta-analysis of substitution value of maize with cassava (Manihot esculenta Cratnz) on growth performance of broiler chickens

Frontiers in Veterinary Science, 2022
There are variable results on the effect of cassava on the performance characteristics of broiler chickens. As a result, this meta-analysis was performed to determine the effect of cassava on feed intake, feed conversion ratio (FCR), and average daily ...

Snps detected in the sirt1 and h-fabp genes and their association with growth traits in yak [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi, 2019
The aims of this study were to investigate whether the Sirtuin 1 (SIRT1) and Hear fatty acid binding protein (H-FABP) genes could be used as candidate genes in the breeding of yak. In 409 indigenous Chinese yaks, two single nucleotide polymorphisms (SNPs)

Polymorphisms in GJA1 and their association with growth traits in chicken

Genetics and Molecular Research, 2015
This study aimed to screen single nucleotide polymorphisms (SNPs) in the chicken gap junction protein alpha 1 (GJA1) gene, and to investigate their association with five growth traits measured in 269 chickens encompassing Chinese indigenous Beijing-You (BJY) and commercial Cobb broiler (CB) populations.
