Content of Docosahexaenoic Acid in Pectoral Muscles of Birds Correlates with Wing Beat Frequency
AbstractDocosahexaenoic acid (22:6n-3, DHA) is a structural component of cell membranes and due to a peculiar form of its molecule exerts a high...

Changes in the wing-beat frequency of bees and wasps depending on environmental conditions: a study with optical sensors
We study how the behavior and wing-beat frequency of hymenopteran flying insects depend on environmental conditions, such as temperature and relative...

Wings are not perfect: increased wing asymmetry in a tropical butterfly as a response to forest fragmentation
Habitat fragmentation and ecosystem changes have the potential to affect animal populations in different ways. To effectively monitor these changes,...

Functional compliance and protective stiffness: cross-veins in the hind wing of locust Locusta migratoria
Locusts ( Locusta migratoria ) have outstanding flying abilities, and most of their lift is provided by their hind wings. Insect aerodynamic...

Novel wing display and divergent agonistic behaviors of two incipient Psolodesmus damselflies
Sexual selection via male competition is a strong evolutionary force that can drive rapid changes in competitive traits and subsequently lead to...

Soaring and intermittent flap-gliding during migratory flights of Northern Bald Ibis
Migratory journeys represent an energetic challenge for many long-distance migrants. The choice of flight times, migration route, altitude,...

Sound vs. light: wing-based communication in Carboniferous insects
Acoustic communication is well-known in insects since the Mesozoic, but earlier evidence of this behavior is rare. Titanoptera, an ‘orthopteroid’...

The advantages and challenges of non-invasive towed PILOT tags for free-ranging deep-diving megafauna
BackgroundBiologging technologies have yielded new insights into the ecology and behaviour of elasmobranchs, but to date, most studies involve animal...

Investigation of central pattern generators in the spinal cord of chicken embryos
For most quadrupeds, locomotion involves alternating movements of the fore- and hindlimbs. In birds, however, while walking generally involves...

Tensile mechanical properties and finite element simulation of the wings of the butterfly Tirumala limniace
This study examined the morphological characteristics and mechanical properties of the wings of Tirumala limniace . The wings of this butterfly,...

Impact of the quality of food sources on the wing beating of honey bee dancers
The waggle dances of honey bees provide information about the location of food sources and their quality. This study aimed to investigate how the...

The effect of a lack of uncapped brood on social interactions between honey bee workers and the queen
Vibro-acoustic communication is used by honey bees in many different social contexts. Our previous research showed that workers interact with their...

Avian Locomotion: Flying, Running, Walking, Climbing, Swimming, and Diving
Most birds can fly, but can also, to varying degrees depending on the species and their habitats, walk, run, climb, swim, and dive. With a focus on...

The impact of shape and attachment position of biologging devices in Northern Bald Ibises
BackgroundThe impact of biologging devices on the aerodynamics or hydrodynamics of animals is still poorly understood. This stands in marked contrast...

Transcriptome dynamics during metamorphosis of imaginal discs into wings and thoracic dorsum in Apis mellifera castes
BackgroundMuch of the complex anatomy of a holometabolous insect is built from disc-shaped epithelial structures found inside the larva, i.e., the...

Volatiles as Attractants of Mahogany Shoot Borer, Hypsipyla grandella Zeller (Lepidoptera: Pyralidae)
The mahogany shoot borer, Hypsipyla grandella Zeller (Lepidoptera: Pyralidae), is one of the most economically important pests in all American...

Novel tag-based method for measuring tailbeat frequency and variations in amplitude in fish
The tailbeat frequency (TBF) together with tailbeat amplitude (TBA) of fish are tightly correlated with swimming speed. In addition, these parameters...

Adaptations for extremely high muscular power output: why do muscles that operate at intermediate cycle frequencies generate the highest powers?
The pectoralis muscles of the blue-breasted quail Coturnix chinensis generate the highest power output over a contraction cycle measured to date,...

Natural History of the Little Bustard: Morphology, Biometry, Diet, Sexual Dimorphism, and Social and Breeding Behaviour
The little bustard Tetrax tetrax is one of the smallest members of the family Otididae, and has many remarkable life history traits, in its anatomy,...

A Study on Allometry of Wing Shape and Venation in Insects. Part 2. Diptera
The research studied how body size affects wing shape and arrangement of veins in a wide range of families of dipteran insects (Diptera). Body mass...
