Linking biosurface reactivity and photosynthesis to investigate Sphagnum mosses as ecosystem engineers

New Phytologist, Volume 252, Issue 1, Page 69-86, October 2026.
Habit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.

Multicenter (FX)n/NH3 Halogen Bonds (X = Cl, Br and n = 1–5). QTAIM Descriptors of the Strength of the X∙∙∙N Interaction

Molecules, 2017
In the present work an in depth deep electronic study of multicenter XBs (FX)n/NH3 (X = Cl, Br and n = 1–5) is conducted. The ways in which X∙∙∙X lateral contacts affect the electrostatic or covalent nature of the X∙∙∙N interactions are explored at the ...

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

Wildlife Monographs, Volume 226, Issue 1, September 2026.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Soundscapes of the Upper Amazon: Seasonal Activity Patterns of Insectivorous Bats in Cordillera Escalera, Peru

Biotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Bats, the second most diverse group of mammals, play essential ecological roles in insect control, pollination, and seed dispersal. In Peru, insectivorous bats remain poorly studied, particularly in high‐elevation rainforest ecosystems of the upper Amazon region.

Digital Rights Activism in Multilevel Governance

European Policy Analysis, Volume 12, Issue 4, Fall 2026.
ABSTRACT Multilevel governance (MLG) without a clear hierarchical structure can create power imbalances among various actors, particularly in settings with overlapping jurisdictions and policy areas. This dynamic is especially pronounced in Internet governance, which faces a complex interplay of domestic laws, state interdependence, and heightened ...

Conservation implications of low contemporary connectivity along the Mid‐Atlantic Ridge in hydrothermal vent gastropods

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Polymetallic sulfide deposits produced at hydrothermal vent fields are targets for mining exploitation along the Mid‐Atlantic Ridge, threatening the functioning and resilience of vent ecosystems that provide multiple ecosystem services. Knowledge about connectivity between vents will inform conservation practices.

A Comprehensive Taxonomy of Rules for Nuanced Analysis of Governance Systems

Policy Studies Journal, Volume 54, Issue 3, August 2026.
ABSTRACT Understanding how institutions shape collective action requires analytical tools that capture the complexity of governance arrangements. Ostrom's typology of rules provides a foundational framework for examining institutional configurations, yet limited specificity in rule types reduces its effectiveness in comparative analysis.
