AGRICULTURE IN A SOCIALIST CITY: Towards an Alter‐Urban Political Ecology

International Journal of Urban and Regional Research, EarlyView.
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,

O dimorfismo dos ramos em Coffea arabica L. [PDF]

Bragantia, 1950
O dimorfismo dos ramos tem sido observado em vários gêneros de plantas, tais como Gossypium, Theobroma, Hedera, Musa, Araucária, Castilla, bem como em Coffea. Tal fenômeno se carateriza por uma diferenciação somática, que, na maioria dos casos, é permanente, podendo-se propagar as diferentes formas pela reprodução vegetativa.

Transcriptional activity, chromosomal distribution and expression effects of transposable elements in Coffea genomes [PDF]

, 2013
Plant genomes are massively invaded by transposable elements (TEs), many of which are located near host genes and can thus impact gene expression. In flowering plants, TE expression can be activated (de-repressed) under certain stressful conditions, both
