Austral Ecology, Volume 51, Issue 3, March 2026.ABSTRACT Plant‐hummingbird interaction networks can be influenced by environmental conditions and resources, which vary seasonally and daily. We aimed to understand how variations in these parameters across these two temporal windows influence patterns of plant‐hummingbird interactions and hummingbirds dominance hierarchies in a Brazilian Cerrado ...

, 2000 We studied the distribution of five pollination modes (ornithophily, chiropterophily, entomophily, mixed/unspecific, autogamy) among the bromeliad communities of 74 forest sites in the Bolivian Andes and adjacent lowlands.

DiversityFlowering plants have evolved a wide range of strategies to avoid self-fertilization. Although allogamy is common among members of the genus Vanilla, V. lindmaniana is widely known for its ability to self-fertilize, resulting in fruit-set rates of 83–100%

Melittophily and Ornithophily of Long-tubed Flowers in Zingiberaceae and Gesneriaceae in West Sumatra [PDF]
, 1993 Pollination of seven zingiberaceous and two gesneriaceous species was studied in natural forests at various altitudes in West Sumatra, Indonesia. Terrestrial, red, long-tubed flowers of Achasma macrocheilos were visited by a large, remarkably long ...

African Journal of Ecology, Volume 63, Issue 4, June 2025.ABSTRACT Bird pollination remains understudied in Madagascar. We document the first recorded observation of common sunbird‐asity Neodrepanis coruscans (Philepittidae), a Malagasy endemic which is not a true sunbird, visiting and potentially pollinating Bakerella clavata, a plant with long tubular flowers.

Influence of floral orientation on feeding behavior in Anna's hummingbirds
Journal of Avian Biology, Volume 2025, Issue 3, May 2025.Hover‐feeding by hummingbirds from pendent flowers relative to horizontal flowers increases the metabolic cost of flight, but in nature a large proportion of hummingbird‐pollinated flowers are nonetheless oriented near‐vertically downward. We used binary‐choice tests to assess behavioral preference of captive Anna's hummingbirds for these two ...
