Hydrazone‐Type Ligands for Asymmetric Catalysis

open access: yesChemistryEurope, Volume 4, Issue 9, September 2026.
The introduction of trans 2,5‐disubstituted pyrrolidines is the key design element enabling the excellent stereocontrol exerted by hydrazone‐based N‐ligands in a variety of transition metal‐catalyzed transformations, including Diels–Alder cycloadditions, Suzuki/Hiyama/Negishi cross‐couplings, 1,2‐additions to a variety of imines and hydrazones, and ...

Second‐order elasticities for ecology and evolution: Unraveling nonlinear fitness responses to perturbations

open access: yesEcology, Volume 107, Issue 9, September 2026.
Abstract In ecology and evolutionary biology, understanding the relationship between vital rates (e.g., survival, development, reproduction) and population growth is essential to elucidate how life history strategies are shaped by natural selection. Yet most established demographic methods rely on linear assumptions that rank the importance of vital ...

Elevated B‐vitamins within a temperate estuary: Strong spatiotemporal dynamics and links to microbial plankton communities

open access: yesLimnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract B‐vitamins are organic cofactors required by prokaryotic and eukaryotic planktonic cells; their availability impacts aquatic microbial communities and associated biogeochemistry. Despite their ecological importance, B‐vitamin dynamics and their relationships to plankton composition in estuaries are unclear, limiting our understanding of ...

Seed co‐occurrence caused by shared frugivores leaves a long‐lasting signal in the spatial co‐occurrence among plants

open access: yesOikos, Volume 2026, Issue 9, September 2026.
Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence. Particularly, generalist avian frugivores forage on them, co‐dispersing and co‐disseminating their seeds.

Identical Platform, Divergent Publics: Sweden and Finland During the 2022 NATO Crisis

open access: yesPolicy &Internet, Volume 18, Issue 3, September 2026.
ABSTRACT Digital platforms are often theorized as universal drivers of political polarization, yet empirical patterns remain inconsistent across countries. Leveraging the natural‐experiment logic of Sweden's and Finland's simultaneous 2022 NATO applications and the NATO–Turkey diplomatic crisis, this study examines how national political cultures ...

An interdisciplinary review of the interplay of conflict, socio‐economic factors, and land cover and vegetation dynamics in Colombia

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1533-1549, September 2026.
Colombia's forests play a crucial role in preserving biodiversity and mitigating climate change, but they are currently facing severe degradation, particularly after the 2016 Peace Agreement. Our literature review highlights a growing research interest in this topic and demonstrates how interdisciplinary approaches combining diverse methods can enhance

Revealing Hidden Impact: Social and Solidarity Economy Enterprise Networks and Sustainable Development in Developing Countries

open access: yesSustainable Development, Volume 34, Issue 5, Page 6021-6041, September 2026.
ABSTRACT The Social and Solidarity Economy (SSE) offers strong potential for sustainable development in low‐income regions, yet its enterprises often operate with scarce resources, weak monitoring systems, and limited visibility. These constraints hinder both their capacity to demonstrate contributions to sustainable development (SD) and their own ...

Why Pediatric Drowning Must Be a Global Health Priority: A Call to Action

open access: yesWorld Medical &Health Policy, Volume 18, Issue 3, September 2026.
ABSTRACT Pediatric drowning is a leading yet underrecognized cause of child mortality worldwide, disproportionately affecting children in low‐ and middle‐income countries (LMICs). While events in high‐income settings often reflect isolated lapses in supervision or safety barriers, in LMICs drowning is driven by structural inequities, including ...

North Atlantic Ocean–Atmosphere Dynamics Controlled the Hydroclimate in Western Iberia During the Holocene

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Hydroclimate variability in western Iberia during the Holocene remains insufficiently resolved despite the high sensitivity of this region to the North Atlantic atmosphere and ocean dynamics. Here, we present the first source‐resolved reconstruction of centennial‐ to millennial‐scale moisture variability over the last 11,000 years using ...
