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

Biotropica, Volume 58, Issue 1, January 2026.Nectar is a highly variable, mostly unpredictable resource in tropical mountains. How do nectarivorous birds such as this male Great Sapphirewing cope? Fine‐scaled tracking of hummingbirds and flowerpiercers shows flexibility in daily movement strategies in the high Andes, possibly in response to fluctuating local conditions such as weather and ...

Foraging Movement Patterns of Lactating Mexican Long‐Nosed Bats in Central Mexico
Ecology and Evolution, Volume 15, Issue 9, September 2025.We tracked 21 lactating females of a migratory and endangered nectar‐feeding bat using GPS devices, and analyzed their foraging movements in one of the most important maternity roosts for the conservation of the species. Bats foraged within 50 km from the roost, made up to three foraging trips on the same night, and visited multiple foraging grounds ...

Functional Ecology, Volume 39, Issue 9, Page 2526-2538, September 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Heterostylous plants are defined by the reciprocal positioning of stigmas and anthers in floral morphs—a trait proposed by Darwin to enhance the efficiency of disassortative (intermorph) pollen transfer.

Distinct Intra‐ and Interspecific Foraging Patterns of Stingless Bee Species as a Conservation Tool
Biotropica, Volume 57, Issue 5, September 2025.In this study, we examined the foraging patterns of three rescued stingless bee species in the Bolivian Yungas using melissopalynology and plant–pollinator network analysis. We found distinct floral foraging patterns both within and among three stingless bee species in the Bolivian Yungas, suggesting niche partitioning at multiple levels.
