Host Abundance Predicts Interactive Roles in Neotropical Bat–Bat Fly Interactions

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We analyzed the influence of bat functional traits on their importance as hosts in bat–bat fly networks. Our results indicate that bat abundance is the main driver for host importance in Neotropical bat–bat fly interactions. ABSTRACT Host functional traits are known to shape host‐parasite interactions across multiple taxa.

Preservative Ethanol From Stomach Contents Is a Reliable Proxy for Diet DNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
We tested whether DNA metabarcoding of preservative ethanol can substitute bulk stomach contents for reconstructing diets. Using two ethanol DNA extraction methods (precipitation and drying), the resulting profiles showed minor differences relative to each other and to bulk contents in richness, composition, and read counts, mostly limited to low ...

Avaliação da compatibilidade entre novos lançamentos em gramíneas e leguminosas sob ação de dois manejos

open access: yesBoletim de Indústria Animal, 2014
O experimento foi conduzido de outubro de 1985 a janeiro de 1988 na Sede do Instituto de Zootecnia em Nova Odessa (SP), objetivando comparar 35 associações de gramíneas e leguminosas, sob efeito de dois manejos simulados: alto e baixo. O delineamento experimental foi o de blocos completos ao acaso, combinando-se sete gramíneas e cinco leguminosas ...

PARAMETRIC STUDY OF THE INFLUENCE OF WIND ON THE DESIGN OF STEEL TUBULAR TOWERS WITH DIFFERENT GEOMETRIES ACCORDING TO THE EUROCODES

open access: yesce/papers, Volume 9, Issue 1, Page 374-383, April 2026.
Abstract The geometries of metallic tubular towers directly influence the interaction between wind action and the structural response of the tower itself. Analyzing these configurations and understanding how this interaction occurs is fundamental for proper structural design.

Cooperative human signals to honeyguides form local dialects

open access: yesPeople and Nature, Volume 8, Issue 3, Page 682-694, March 2026.
Abstract Human language enables the exchange of complex information and precise instructions for collaborative planning and action. It rapidly evolves through social learning, generating diverse cultural communication signals used not only with other humans, but also with domesticated animals bred or trained to respond.

Exposing and Reducing Biases of Simulating Mixed‐Phase Clouds in the Convection‐Permitting E3SM Atmosphere Model: Lessons From an Arctic Cold‐Air Outbreak

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Mixed‐phase clouds modulate the water and energy cycles of high‐latitude regions, yet their liquid‐ice phase partitioning has long been poorly simulated in climate models. Here, simulations of Arctic mixed‐phase clouds by the Simple Cloud‐Resolving E3SM Atmosphere Model (SCREAM) are assessed against large‐eddy simulations, satellite data, and ...
