Foraging plasticity and physiological adaptations enable hummingbirds to subsist on dilute nectars

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1475-1490, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Hummingbirds frequently feed on small volumes (<30 μL) of sucrose‐rich nectars. Climate change is expected to affect both the abundance and the concentrations of accumulated nectar.

Understanding the Link Between Policy Design and Distributional Impacts of Local Wind Energy Ordinances

open access: yesReview of Policy Research, Volume 43, Issue 3, May 2026.
ABSTRACT Zoning is one of the most widely used land use regulations in the U.S. An increasing number of local governments have adopted zoning ordinances to regulate renewable energy projects. However, there has been very limited research on the impact of this local regulatory tool.

Dual Role of Ti3C2Tx MXene in Li–S Batteries: Cathode Additive and Separator Modifier for Enhanced Performance

open access: yesAdvanced Functional Materials, Volume 36, Issue 29, 9 April 2026.
Ti3C2Tx MXene has been novelly proposed as a simultaneous bifunctional material in Li‐S battery cathodes and separators. The synergistic effect of this material demonstrates significant improvements in electrochemical performance, reaching initial areal capacity values close to 6 mAh cm−2 with ultra‐high sulfur loading of 9 mg cm−2 and ultra‐high ...

Local climate and genetic influence on intraspecific variation in torpor physiology of a cave‐roosting bat

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 857-867, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many small endotherms employ torpor as a survival strategy to reduce energy expenditure during periods with low food availability and cold temperatures. The expression and physiology of torpor can vary substantially within species because of phenotypic plasticity and ...

Relación entre el mérito genético para la producción de leche y el desempeño metabólico y reproductivo en la vaca de alta producción Relations among the genetic merit to milk yield and metabolic and reproductive performance of high production cows

open access: yesRevista Colombiana de Ciencias Pecuarias, 2005
A la vez que ha aumentado la ganancia genética para la producción de leche, el desempeño reproductivo de las vacas ha desmejorado simultáneamente; sin embargo, las razones fisiológicas de este antagonismo no están bien determinadas.
