Landraces are important genetic resources that have a significant role in maintaining the long-term sustainability of traditional agro-ecosystems, food, nutrition, and livelihood security. In an effort to document landraces in the on-farm conservation co
these goods are called complements in production. This occurs when the production of one good automatically produces another good as a byproduct or a kind of side-effect of the production process. Sometimes one product might be a byproduct of another, but have value for use by...
Farmers throughout Mesoamerica continue to grow maize in variants of the milpa system in a range of agro-ecologies from arid and semiarid zones to the temperate highlands and tropical lowlands. In addition to being intercropped with common beans and squash, maize may be grown with faba beans (...
6]. Through WGD events, tandem repeats, transposable element-mediated repeats, and retrotransposon duplications, genomes can increase in size and gene number. This results in the generation of structurally and functionally similar gene copies and formation of gene...
We highlight the importance of drones to queen success and fitness in many ways, and suggest future research exploring impacts of this often-neglected caste. Keywords: Bombus; bumble bee; male; mating; immunity; queen success 1. Introduction Bumble bees have been increasingly used for crop ...
the involvement of PME and PMEI in regulating monocot pollen tube development is still poorly understood. To investigate their importance in the development of rice pollen, we first assessed the effects of pollen tube growth following the addition of a PME enzyme and PME-inhibiting catechin extract...
These activities could include improved crop and grazing land management—for instance, more efficient fertilizer use to prevent the leaching of unused nitrates, tillage practices that minimize soil erosion, the restoration of organic soils, and the restoration of degraded lands. In addition, the ...
In addition to M. flexuosa, the Maijuna use over 60 different species of plants from aguajales. When M. flexuosa is in fruit, aguajales are important hunting areas with a total of 20 different animal species hunted. The Maijuna also have traditional beliefs about aguajales, believing that ...
In addition, s/he has a good command over the villagers. SAAO and the village head started all the FGDs by familiarising the researcher with the participants and expressing the objective of the FGDs conduction. In the FGDs, both men and women were in the same group during the interviewing....
crop production per acre increased dramatically. Between 1940 and 1980 in the United States, for example, per-acre yields ofcorntripled, those ofwheatandsoybeansdoubled, and farm output per hour of farm work increased almost 10-fold as capital was substituted for labour. New techniques offood...
