Abstract Classical urban geography theories determine the distribution of population, production and economic activities on geospatial features. Under this assumption, peripheral regions are rarely prosperous. Depopulation, weak industrial and employment structure and inefficient and fragmented land use form a negative feedback loop. Within the context

Summary In response to challenges from herbivores and competitors, plants use fitness‐limiting resources to produce (auto)toxic defenses. Jasmonate signaling, mediated by MYC2 transcription factors (TF), is thought to reconfigure metabolism to minimize these formal costs of defense and optimize fitness in complex environments.

Field‐based mechanical phenotyping of cereal crops to assess lodging resistance
Plant mechanical failure, also known as lodging, is the cause of significant and unpredictable yield losses in cereal crops. Lodging occurs in two distinct failure modes—stalk lodging and root lodging. Despite the prevalence and detrimental impact of lodging on crop yields, there is little consensus on how to phenotype plants in the field for lodging ...
