Coinvasional disruptions to island pollinator networks

open access: yesConservation Biology, EarlyView.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

Elevation shapes alpine snow algal blooms and their influence on albedo reduction

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2482-2496, September 2026.
Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.

Maximum water stress is decoupled from climate, traits, and growth in a xeric oak

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2392-2406, September 2026.
We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

Commissioning and clinical positioning assessment of a novel surface‐guided radiation therapy (SGRT) system at a C‐Arm linear accelerator

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Surface‐guided radiation therapy (SGRT) has been increasingly adopted in modern radiotherapy, enabling radiation‐dose‐free, marker‐free patient positioning with high accuracy. A novel SGRT system, LUNA 3D (LAP, Lüneburg, Germany), featuring a browser‐based interface, GPU‐accelerated surface reconstruction, high frame rates, large ...

Oligoprogressive renal cell carcinoma: What is the role of surgery?

open access: yesBJU International, Volume 138, Issue 2, Page 219-228, August 2026.
Objective To provide an overview of the biological mechanism and pattern of oligoprogression in renal cell carcinoma (RCC) and the most updated role of surgery in this setting, highlighting scientific gaps and informing future implications. Methods A non‐systematic search of PubMed/MEDLINE was performed in August 2025 including guidelines, reviews, and

An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

Feasibility and Safety of High‐Dose Proton Re‐Irradiation in Recurrent Pediatric Central Nervous System Tumors: A Single‐Institution Retrospective Study

open access: yesPediatric Blood &Cancer, Volume 73, Issue 7, July 2026.
ABSTRACT Purpose Pediatric central nervous system (CNS) tumors often recur despite multimodality therapy. Although re‐irradiation (re‐RT) has historically been limited by concerns for severe late toxicities, modern techniques have renewed interest in this approach. Proton therapy provides dosimetric advantages that may enable curative re‐treatment with
