How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, EarlyView.
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 ...

The Orientation of Visual Space from the Perspective of Hummingbirds

open access: yesFrontiers in Neuroscience, 2018
Vision is a key component of hummingbird behavior. Hummingbirds hover in front of flowers, guide their bills into them for foraging, and maneuver backwards to undock from them.

Kinematics of hovering hummingbird flight along simulated and natural elevational gradients [PDF]

open access: yes, 2003
Hovering flight is one of the most energetically demanding forms of animal locomotion. Despite the cost, hummingbirds regularly hover at high elevations, where flight is doubly challenging because of reduced air density and oxygen availability.

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

open access: yesEcography, EarlyView.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Using Pop-GUIDE to Assess the Applicability of MCnest for Relative Risk of Pesticides to Hummingbirds

open access: yesEcologies, 2023
Hummingbirds are charismatic fauna that provide important pollination services, including in the continental US, where 15 species regularly breed. Compared to other birds in North America, hummingbirds (family Trochilidae) have a unique exposure route to

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Effects of a snowstorm event on the interactions between plants and hummingbirds: fast recovery of spatio-temporal patterns

open access: yesRevista 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

Genetic Toolkit for Assessment and Prediction of Population-Level Impacts of Bridge Construction on Birds [PDF]

open access: yes, 2020
Recent studies have highlighted alarming rates of declines in bird populations across the country. The State of California is home to over 650 resident and migrant avian species. Legislation for protecting these species has existed for over a century now,
