High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

High-resolution in situ imaging reveals size-specific moonlight responses in zooplankton diel vertical migration

open access: yesScientific Reports
Light is the primary cue driving zooplankton diel vertical migration (DVM), a strategy that balances predation risk with resource access. However, DVM is often oversimplified, with limited consideration of how light-driven risks and resource needs vary ...

Linking community structure and climate vulnerability in desert plant assemblages of southern California

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

The Role of the Gut Microbiota in Allogeneic Hematopoietic Cell Transplantation

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Allogeneic hematopoietic cell transplantation (allo‐HCT) is an effective treatment for patients with high‐risk hematologic malignancies. Over the last decade, gut microbiota composition during allo‐HCT has been associated with patients' outcomes.

Altered Nasal Microbiota in Sinonasal Tumors: A Comparative Analysis of Malignant and Benign Sinonasal Tumors

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Although shifts in nasal microbiota have been well‐documented in inflammatory upper airway conditions, microbiota tumor‐associated alterations remain uncharacterized. This study is the first to compare sinonasal microbiota profiles of patients with malignant tumors (MT), benign tumors (BT), and controls, offering insights into tumor‐

Evaluating the sustainability of impounded river systems and the cost-effectiveness of dam projects: An ecosystem services approach

open access: yes
In recent times, there has been increasing demand in the Canterbury region of New Zealand for the abstraction of water from rivers. The impact of this demand has lead to unacceptable minimum river flows and has adversely affected river ecology.
