Plant Biology, EarlyView.For most traits, floral intra‐individual variation was similar between morphs and populations with different pollinator guilds (bees and hummingbirds), potentially facilitating effective pollen transfer in distylous systems. Still, greater variation in corolla length increased pollen deposition in L‐morph flowers in the bee‐pollinated population ...

How hummingbirds hum: acoustic holography of hummingbirds during maneuvering flight [PDF]
, 2017 Hummingbirds make a characteristic humming sound when they flap their wings. The physics and the biological significance of hummingbird aeroacoustics is still poorly understood. We used acoustic holography and high-speed cameras to determine the acoustic

Revista Mexicana de Biodiversidad, 2011 The global climatic change could cause, in some places, appearance of meteorological phenomena considered rare. If we understand the effect of these phenomena on birds we can understand how birds respond to weather changes. We report here the effect of a

Preference assessment and reinforcer effectiveness in domestic cats
Journal of the Experimental Analysis of Behavior, Volume 126, Issue 3, November 2026.Abstract Understanding domestic cat (Felis catus) preferences is important for identifying effective reinforcers that can support training, enrichment, and welfare. We assessed preference across three stimulus categories (food, toys, and social interaction) using free‐operant assessments with four adult cats in familiar home environments.

The Anatomical Record, Volume 309, Issue 10, Page 2725-2738, October 2026.Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Nexus file for: Molecular diversification of hummingbirds
, 2022 The tempo of species diversification in large clades can reveal fundamental evolutionary mechanisms that operate on large temporal and spatial scales. Hummingbirds have radiated into a diverse assemblage of specialized nectarivores comprising 338 species,

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts
Biological Reviews, Volume 101, Issue 5, Page 2081-2102, October 2026.ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...
