Outperforming hummingbirds’ load-lifting capability with a lightweight hummingbird-like flapping-wing mechanism

open access: yesBiology Open, 2016
The stroke-cam flapping mechanism presented in this paper closely mimics the wing motion of a hovering Rufous hummingbird. It is the only lightweight hummingbird-sized flapping mechanism which generates a harmonic wing stroke with both a high flapping ...

Latitudinal effect on the structure of snake–prey interaction networks is mediated by snake species richness

open access: yesEcography, Volume 2026, Issue 10, October 2026.
Despite the growing number of studies on trophic networks in recent decades, there are still important gaps in our understanding of how these networks are structured across broad environmental gradients. These gaps are even greater in some groups of terrestrial vertebrates, such as snakes, requiring a cohesive synthesis of their broader trophic ...

Mixtures of Neural Network Experts With Application to Phytoplankton Flow Cytometry Data

open access: yesEnvironmetrics, Volume 37, Issue 7, October 2026.
ABSTRACT Flow cytometry is a valuable technique that measures the optical properties of particles at a single‐cell resolution. When deployed in the ocean, flow cytometry allows oceanographers to study different types of photosynthetic microbes called phytoplankton.

Pollen landscape saturation on pollinator bodies reduces pollen deposition by subsequently visited bat‐pollinated flowers

open access: yesFunctional Ecology, Volume 40, Issue 10, Page 3190-3199, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Sexual selection in flowering plants often operates through male–male competition, yet the mechanisms underlying this phenomenon remain difficult to demonstrate. One potential arena for such competition is pollen placement on pollinators, where pollen grains from ...

Evaporative water loss and dehydration during the night in hummingbirds Pérdida de agua evaporativa y deshidratación nocturna en picaflores

open access: yesRevista Chilena de Historia Natural, 2007
Nectar-feeding birds oscillate between avoiding overhydration when they are feeding and preventing dehydration during fasts. Here, we examined how resting rates of total evaporative water loss (TEWL) and metabolic water production (MWP) influence water ...

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

open access: yesJournal of Animal Ecology, Volume 95, Issue 10, Page 1876-1886, October 2026.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.
