Three-Photon Stokes Mueller Polarimetry

open access: yes, 2015
The generalized theory of Stokes Mueller polarimetry is employed to develop the third-order optical polarimetry framework for third-harmonic generation (THG). The outgoing and incoming radiations are represented by 4-element and 16-element column vectors,

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

open access: yesConservation Biology, EarlyView.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Effects of Partner Workload and Increasing Environmental Temperature on Nestling Provisioning and Body Temperature in a Declining Aerial Insectivore

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 4, Page 414-426, May 2026.
ABSTRACT With climate change, birds will face increasing thermoregulatory demands, which may alter reproductive behaviors such as offspring provisioning. Experimental studies have shown that the provisioning capacity of female tree swallows (Tachycineta bicolor) is limited by their risk of overheating. Given that parental investment strategies may vary

Engineering the 3′‐UTR of Tobacco Vein Mottling Virus to Confer Cross‐Protection Against Potyviruses

open access: yesMolecular Plant Pathology, Volume 27, Issue 5, May 2026.
The 3′‐untranslated region (3′‐UTR) and its secondary structure of virus genomic RNA of tobacco vein mottling virus (TVMV) are important in symptoms attenuation, which can be engineered for cross‐protection against further viral infection. We provide experimental evidence that supports the roles of 3′‐UTR in potyvirus infection.

Divergent shifts in hydraulic versus carbon acquisition functional traits after wildfire in four Rocky Mountain tree species

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 1100-1117, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change has increased the frequency and severity of drought and large wildfire events across western North America. Despite the increasing concurrence of drought and wildfire events and the importance of forests as a global carbon sink, the impacts of fire on ...
