AGRICULTURE IN A SOCIALIST CITY: Towards an Alter‐Urban Political Ecology
Abstract Urban political ecology has developed as a critique of capitalist urbanization. This article develops the concept of alter‐urban political ecology to define urban environments emerging not from capitalist urbanization but from efforts to transform it. Drawing on archival research and ethnographic fieldwork in five urban farms in socialist Cuba,

Metabolism and Excretion of Caffeine during Germination of Coffea arabica L. [PDF]
To investigate the physiological role of the purine alkaloids during germination, seeds of Coffea arabica were allowed to germinate under aseptic conditions on agar at 26°C, either in the dark or in the light. After imbibition for 7 days less than 1% of the seed caffeine is found in the agar, indicating a strong diffusion barrier at the surface of the ...

MeJA application strengthened both direct and indirect coffee defenses against the white mealybug Planococcus citri, whereas the effects of MeSA were variable and context‐dependent across the defensive traits examined. The combined application of both elicitors produced an effect similar to MeSA on direct defenses, but resembled MeJA when indirect ...

ABSTRACT Sesame (Sesamum indicum L., 2n = 26) is one of the oldest oilseed crops and is often called the ‘queen of oilseeds’ due to its high content of unsaturated fatty acids and natural antioxidants. Despite its long history, the origin and global spread of cultivated sesame remain unresolved.

Additive Variance and Open‐Pollinated Progenies Under Mixed Mating
ABSTRACT Open‐pollinated progeny tests are still widely interpreted as if all the individuals within a maternal family were true half‐sibs. However, in species with mixed mating systems, this assumption is often biologically unrealistic and may bias the estimation of the additive variance, narrow‐sense heritability and expected selection gains.

ABSTRACT Background and Aims Cardiovascular diseases (CVDs) remain the leading cause of global morbidity and mortality, encompassing coronary artery disease, hypertension, heart failure, and cerebrovascular disorders. The global burden of CVD continues to rise, driven by complex interactions among endothelial dysfunction, oxidative stress, inflammation,

Strategies to reconstruct 3D Coffea arabica L. plant structure [PDF]
Accurate model of structural elements is necessary to model the foliage and fruit distributions in cultivated plants, both of them being key parameters for yield prediction. However, the level of details in architectural data collection could vary, simplifying the data collection when plants get older and because of the high time cost required.

Este trabalho teve como objetivo avaliar a produção de matéria seca, o crescimento radicular e a absorção e distribuição do Ca, P e Al nas folhas, no caule e nas raízes de dois clones de café conilon (Coffea canephora) (Mtl 25 e Mtl 27) e de uma ...

Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...

The global coffee industry, supporting 25 million smallholder farmers, is vulnerable to climate change. Diversifying the coffee species portfolio beyond Arabica and robusta is a promising intervention. Liberica coffee could provide adaptive capacity, although its climate parameters for cultivation are poorly known.
