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,

Additive Variance and Open‐Pollinated Progenies Under Mixed Mating

Plant Breeding, EarlyView.
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.

Acute Caffeine Intake Does Not Modulate Active or Reactive Inhibition in Non‐Clinical Young Adults, and ADHD Symptoms Do Not Moderate Its Effects

Human Psychopharmacology: Clinical and Experimental, Volume 41, Issue 6, November 2026.
ABSTRACT Background Caffeine is consumed for its presumed cognitive benefits, yet controlled studies have repeatedly failed to find effects on inhibitory control. Cross‐sectional work suggests that people with elevated attention‐deficit/hyperactivity disorder (ADHD) symptoms may benefit from chronic, moderate caffeine consumption, but whether acute ...

Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, Volume 8, Issue 6, Page 1989-2004, November 2026.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Methyl Jasmonate and Methyl Salicylate Differentially Modulate Direct and Indirect Defenses in Coffee Plants Against the White Mealybug

Entomologia Experimentalis et Applicata, Volume 174, Issue 11, Page 1322-1333, November 2026.
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 ...
