Ecography, 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
Environmetrics, 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.

Functional 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 ...

Basis of the vocal communication in hummingbirds [PDF]
, 2023 Although hummingbirds draw attention to their unique hovering flight, as other birds, they strongly rely on sounds to communicate. As songbirds and parrots, hummingbirds convergently evolved the capacity of learning how to produce certain vocalizations ...

Journal 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.
