Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]
Biol Rev Camb Philos SocABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

People and Nature, Volume 8, Issue 6, Page 1943-1956, June 2026.Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

Sustainable Development, Volume 34, Issue 2, Page 2427-2442, April 2026.ABSTRACT Female empowerment and its use in development contexts has histories in coloniality.

The “Pesticide Chip”: Chemical Legacies and Agrarian Futures in Costa Rica
Antipode, Volume 58, Issue 2, March 2026.Abstract For decades, agro‐industrial capital has adopted cascading chemical and biotechnical interventions, or fixes, to secure accumulation through the cultivation of monocrops. We develop a framework that centres on how monocrop‐induced susceptibility to pests and pathogens—and the patchwork of fixes to address these—produces uneven chemical ...

Anaemic Streams: Iron and Essential Trace Metals Frequently Limit Primary Producer Biomass
Ecology Letters, Volume 29, Issue 3, March 2026.Nutrient enrichment experiments in 41 streams across the eastern United States demonstrate that trace metals can limit the growth of primary producers. Trace metals are frequently co‐limiting with macronutrients and the availability of N and P in streams and watersheds are predictive of Fe and Zn limitation status.
