in order to study the effects of co2 enrichment on growth and competitiveness of soybean (glycine max) and millet (panicum miliaceum) against redroot pigweed (amaranthus retroflexus) and lambsquarter (chenopodium albam) an experiment was conducted using two co2 concentrations (350 and 700 ppm). for evaluating effects of co2 variation on inter-and intra-specific competition plants were grown in ...

â â â  â â  abstract: â  china and asean have been maintaining a relationship both cooperative and competitive in the textile trade. due to its labor intensive feature and high dependence on foreign trade , the textile trade has received much attention after the 2008 financial crisis. the customs data (classified by the hs code) from year 2006-2009 is employed to research the impact of the cris...

dna barcoding based on a standardized region of 648 base pairs of mitochondrial dnasequences from cytochrome c oxidase 1 (cox1) is proposed for animal species identification.recent studies suggested that dna barcoding has been effective for identifying 94% of birdspecies. the proposed threshold of 10 times the average intraspecific variation could be used forthe identification and delimitation ...

Unicolonial ant species live in interlinked populations known as super-colonies, where workers and queens move freely. New research suggests that low intra-specific resource competition leads to an absence of inter-colony aggression.

Apomixis, asexual reproduction through seeds, occurs in over 40 plant families. This widespread phenomenon can lead to the fixation of successful genotypes, resulting in a fitness advantage. On the other hand, apomicts are expected to lose their fitness advantage if the environment changes because of their limited evolutionary potential, which is due to low genetic variability and the potential...
