Farmers' perceptions on the causes of cassava root bitterness: a case of konzo-affected Mtwara region, Tanzania por Imakumbili, M.L., Semu, E., Semoka, J.M., Abass, A., Mkamilo, G.

“…Increased cassava root bitterness is often associated with an increase in cyanogenic glucoside levels, making it a good indicator of changes in root cyanogenic glucoside content. Bitter cassava varieties that are preferentially planted by people living in most konzo-affected areas, are an additional known contributor to high cyanogenic glucosides. …”

Silence speaks out loud: Armed conflict and bovine livestock in Colombia, a historical perspective por Triana Ángel, Natalia, Burkart, Stefan

“…Drawing from the experience of Central American communities who, also devastated by recent civil wars, have understood the pivotal function of bovine livestock production as an engine for change and improved livelihoods, we propose a third possible interpretation: one that accounts for the convoluted historical connections between wartime dynamics and cattle and dairy production in Colombia, acknowledges its capacity to empower rural communities in post-conflict contexts and deciphers academic silences as testimonies of its own, violent times. …”

Hunting territories and land use overlap in sedentarised Baka Pygmy communities in southeastern Cameroon por Fa, J.E., Brull, G.R., Martín, E.Á., Okale, R., Fouda, F., Farfán, M.A., Cain, B., Fisher, R., Coad, L.M., Funk, S.M.

“…A significant number of Baka Pygmies in Cameroon have been sedentarised in roadside villages, in contrast to their nomadic hunter-gatherer existence of the past. Although this change in lifestyle has had important consequences on health, most Baka villages still supplement their diets from forest products, especially wild meat. …”

A comparison of differential gene expression in response to the onset of water stress between three hybrid Brachiaria genotypes por Jones, Charlotte, Vega, José de, Worthington, Margaret, Thomas, Ann, Gasior, Dagmara, Harper, John, Doonan, John, Fu, Yuan, Bosch, Maurice, Corke, Fiona, Arango, Jacobo, Cardoso Arango, Juan Andrés, Jiménez, Juan de la Cruz, Armstead, Ian, Fernandez-Fuentes, Narcis

“…Across all genotypes, analysis of DEG enzyme activities indicated an excess of down-regulated putative apoplastic peroxidases in the roots as water stress increased. This suggests that changes in root cell-wall architecture may be an important component of the response to water stress in Brachiaria.…”
