The scaling of seed‐dispersal specialization in interaction networks across levels of organization

open access: yesEcography, Volume 2026, Issue 5, May 2026.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Colonization and extinction mediate environmental effects on the phylogenetic diversity of invertebrate communities

open access: yesEcology, Volume 107, Issue 5, May 2026.
Abstract Phylogeny offers a powerful framework for understanding mechanisms driving community assembly. Yet, most empirical studies in community phylogenetics rely on observational approaches. In this study, we explore how two important drivers of community assembly—habitat size and predator presence—shape species richness and phylogenetic relatedness ...

Element concentrations in tissues reveal spatial structure of Atlantic walrus management stocks

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Differences in tissue element concentrations confirm geographic differentiation between 2 of Canada's walrus management stocks but reveal additional spatial structure within the largest stock that may have management implications. Abstract Ensuring harvested animal populations are managed at appropriate scales requires an understanding of underlying ...

Soil properties and road proximity likely influence plant and bacterial traits and diversity more than habitat size in small urban greenspaces

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 878-891, May 2026.
The global decline in biodiversity can be partly ameliorated by sympathetic design of green spaces within urban environments. This includes roundabouts on road systems. This study utilised a combination of approaches to assess levels of plant and bacterial diversity in roundabouts of varying size, soil characteristics and habitat complexity.

Shipboard Marine Gravimeters Operated on Vessels in the U.S. Academic Research Fleet: Capabilities and Data Quality

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Shipboard gravity anomaly data provide high‐resolution information for a wide range of Earth and ocean science research as well as ground‐truthing US national geodetic modeling. Motivated by the end of life‐cycle for legacy Bell aerospace marine Gravity Meter system (BGM‐3) gravimeters onboard vessels in the U.S. Academic Research Fleet, a new

Interior Rifting Coupled With Peripheral Subduction in the Rodinia Supercontinent: New Insights From the Tarim Craton

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract After assembly, supercontinents are shaped by internal rifting and peripheral subduction. However, the geodynamic relationship between these two processes and their respective contributions to supercontinent breakup remain poorly understood.

Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The Ediacaran Period (∼635–539 Ma) represents a critical interval in Earth's evolution, yet its paleomagnetic record remains complex and contentious. One of the few Ediacaran paleomagnetic results from Baltica considered robust is a pole from the ca.

Hunga‐Tonga Volcano Plumbing System Inferred From Virtual Seismometer Approach

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract We present a surface wave tomography application based on event‐pair interferometry to investigate local (∼100 km) mid‐ocean crustal structures, with a particular focus on imaging a potential crustal solidified intrusive complex in a region lacking seismic stations.

Block‐in‐Matrix Deformation and Veining in Alpine Subducted Oceanic Metasediments at Blueschist Facies Conditions

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract In subduction zones, the locked seismogenic zone is bordered by an upper and a lower transition zone. In these transition zones, deformation is primarily accommodated by an interplay of diffuse viscous deformation within a weak matrix and brittle deformation in stiffer bands and blocks.
