Are large-scale distributional shifts of the blue-winged macaw (Primolius maracana) related to climate change?
(Wiley-Blackwell, 2007-05-01)
Aim To evaluate whether observed geographical shifts in the distribution of the blue-winged macaw (Primolius maracana) are related to ongoing processes of global climate change. This species is vulnerable to extinction and ...

Modified unsteady vortex-lattice method to study flapping wings in hover flight
(Amer Inst Aeronaut Astronaut, 2013-09)
A numerical-simulation tool is developed that is well suited for modeling the unsteady nonlinear aerodynamics of flying insects and small birds as well as biologically inspired flapping-wing micro air vehicles. The present ...
Heritability, phenotypic and genetic correlations of size and shape of Drosophila mediopunctata wings
(Nature Publishing GroupLondonInglaterra, 1999)
Computational dynamics of flapping wings in hover flight: A co-simulation strategy
(Amer Inst Aeronaut Astronaut, 2017-06)
A co-simulation strategy for modeling the unsteady dynamics of flying insects and small birds as well as biologically inspired flapping-wing micro-air-vehicles is developed in this work. In particular, the dynamic system ...
Biomimicry and aerodynamic performance of multi-flapping wing drones
(2021-01-01)
Certain birds have been noted to fly in V-formation, an arrangement which may be used to conserve energy when migrating over long distances without stopping and feeding. The use of such grouping arrangement and organized ...
Right-wing immigration narratives in Spain: A study of persuasion on Instagram Stories
Ephemeral media has become a staple of today’s social media ecology. This study advances the first exploratory analysis of Instagram Stories as a format for political communication. Through an initial content analysis of ...
Sound amplification by means of a horn-like roosting structure in Spix's disc-winged bat
(2013-10)
While sound is a signal modality widely used by many animals, it is very susceptible to attenuation, hampering effective long-distance communication. A strategy to minimize sound attenuation that has been historically used ...
A call-and-response system facilitates group cohesion among disc-winged bats
(2013)
Acoustic signals are important in maintaining group cohesion, particularly in highly mobile species. For these signals to facilitate group cohesion, individuals must be able to recognize, and respond to, calls emitted by ...
