Shrubs inhibit plant diseases by intercepting light in alpine meadows
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change is disproportionately impacting mountain ecosystems, leading to widespread shrub expansion into alpine meadows. Shrub encroachment alters the albedo, carbon budget and warming rate in alpine grasslands, but it remains challenging to predict how shrub ...

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,

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)
Insect Science, EarlyView.As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...
