The complex interaction between mammalian herbivores, climate, soil and fire has shaped the evolution and distribution of plant spinescence across biogeographical realms

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3640-3655, September 2026.
Evolution of spinescence in mimosoid legumes. Summary The evolutionary arms race between plants and herbivores led to numerous plant adaptations, including spinescence. However, the balance between herbivory and abiotic conditions in the evolution of spinescence remains unclear. We integrated phylogenetic, geographic, and trait data for 2686 species of

The impact of tropical forests on local climate: Comparing recent research with conservation practitioner information priorities

open access: yesPeople and Nature, Volume 8, Issue 8, Page 2828-2846, August 2026.
Abstract The local‐scale climate impacts of tropical forests (LCIF), such as reducing temperatures and increasing rainfall, are directly relevant to climate change adaptation and mitigation. Strengthening understanding of these local climate benefits can encourage actions to conserve natural forests, with positive implications for climate resilience ...

Forest Responses to Fire Regime in the Humid Chaco of Paraguay

open access: yesApplied Vegetation Science, Volume 29, Issue 3, July/September 2026.
Fire regimes are increasingly shaping vegetation dynamics in the Humid Chaco of Paraguay, a poorly studied fire‐prone region. Our findings highlight resprouting as a key functional trait associated with fire disturbance. Although vegetation structure varied little among regimes, preserving forest patches may help maintain landscape heterogeneity and ...

Environmental Drivers and Biogeographic Patterns of South American Endemic Ants: Insights From IUCN Red List Assessments

open access: yesJournal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim South American endemic ants play a central role in terrestrial ecosystems but remain poorly integrated into continent‐scale conservation assessments. Their distributions and community composition have likely been shaped by past climatic dynamics and persistent refugia.
