Response of specific leaf area to light: comparative study of a large species set

open access: yesOikos, Volume 2026, Issue 6, June 2026.
Specific leaf area (SLA) is a commonly used proxy for the leaf economy spectrum in plants, separating species with low‐cost leaves (in terms of carbon) with short lifespan and hence fast turnover from species with high‐cost and long‐lived leaves. While SLA is used mainly for interspecific comparisons, it also varies within species both ontogenetically ...

Beautiful and Useful: Species Richness and the Ecosystem Services of Allotment Gardens in Berlin, Germany

open access: yesPlant-Environment Interactions, Volume 7, Issue 3, June 2026.
ABSTRACT Intensive agriculture and urbanization have led to habitat degradation and fragmentation, reducing plant diversity and subsequently reducing pollinator abundance and richness. This paper investigates the conservation potential of green infrastructure in allotment gardens, which are a common form of urban land use.
