Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1270-1285, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...

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.

Simulating drying and human impacts on river networks to evaluate biological quality indices performance through the lens of metacommunity theory

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
This work constitutes a first step towards developing simulation‐based assessments that incorporate catchment drying patterns to support biomonitoring of drying river networks. Our approach can inform stakeholders when current methods are likely to fail and contribute to decision‐making on whether adapting current methods is possible or developing new ...

Effects of climatic changes on the establishment of Mediterranean crops [PDF]

open access: yes, 2008
Temperature, water and light affect directly crop growth and development. Extremes variations of soil temperature near the surface of bare soils and quick changes of soil water content due to irregular rainfall and high evaporative demand affect markedly

Exploring Acoustic Overlap in Second Language Vowel Productions

open access: yesInternational Journal of Applied Linguistics, Volume 36, Issue 2, Page 1293-1304, May 2026.
ABSTRACT This study examines the alignment of vowel categories between second language (L2) learners and first language (L1) speakers of the target language, as well as potential overlaps between adjacent vowels in terms of formant frequencies and duration.

Análise matemática e biológica dos modelos de estimativa de perdas de rendimento na cultura devido à interferência de plantas daninhas. [PDF]

open access: yes, 2016
As plantas daninhas acarretam reduções no rendimento das culturas agrícolas. Os modelos matemáticos de estimativa de perda de rendimento na cultura devido à interferência dessas plantas podem ser instrumentos úteis à tomada de decisão de manejo.
