Differential Flight Capacity of Spissistilus festinus (Hemiptera: Membracidae) by Sex and Age
The three-cornered alfalfa hopper (TCAH), also known as Spissistilus festinus (Hemiptera: Membracidae), infests legumes and poses a threat to the...

Palaeoatmosphere facilitates a gliding transition to powered flight in the Eocene bat, Onychonycteris finneyi
The evolutionary transition to powered flight remains controversial in bats, the only flying mammals. We applied aerodynamic modeling to reconstruct...

Relationships of wingtip shape, song-flight and mating success in male black-headed buntings Emberiza melanocephala
Wing design in birds is the result of different and potentially opposing natural selection pressures, such as those related to migration, predator...

Environmental niche and flight intensity are associated with molecular evolutionary rates in a large avian radiation
BackgroundMetabolic activity and environmental energy are two of the most studied putative drivers of molecular evolutionary rates. Their extensive...

Develo** an efficiency and energy-saving nitrogen management strategy for winter wheat based on the UAV multispectral imagery and machine learning algorithm
Remote sensing has been used for assisting the precision nitrogen (N) management in wheat ( Triticum aestivum ) production. This study aimed to develop...

Sex specificity of dispersal behaviour and flight morphology varies among tree hollow beetle species
BackgroundFlight performance and dispersal behaviour can differ between sexes, resulting in sex-biased dispersal. The primary sex ratio of...

Rapid flight feathers moult and fat stores in the Common Snipe Gallinago gallinago in the early stage of autumn migration
We analysed primary and secondary feather moult and fat reserves in 539 Common Snipes captured in the middle Pripyat River Valley, an important...

Flight rapidly modulates body temperature in freely behaving bats
BackgroundBats are remarkable in their dynamic control over body temperature, showing both hypothermia with torpor and hyperthermia during flight....

Effects of Miniaturization on Wing Structure and Flight Mechanics in Insects
AbstractMiniaturization is one of the principal trends in the evolution of winged insects (Pterygota), in many groups of which miniature forms with...

Paradoxes of Hymenoptera flight muscles, extreme machines
In the Carboniferous, insects evolved flight. Intense selection drove for high performance and approximately 100 million years later, Hymenoptera...

Markerless tracking of bumblebee foraging allows for new metrics of bee behavior and demonstrations of increased foraging efficiency with experience
Bumblebees have become model organisms for cognitive ecology and social learning. Quantifying the foraging behavior of free-flying bees, however,...

Rad regulation of CaV1.2 channels controls cardiac fight-or-flight response
Fight-or-flight responses involve β-adrenergic-induced increases in heart rate and contractile force. In the present study, we uncover the primary...

Energy Balance and Thermoregulation
Birds are endotherms and maintain their body temperatures with heat produced by cell metabolism. The energy consumed at rest, or the basal metabolic...

The species-specificity of energy landscapes for soaring birds, and its consequences for transferring suitability models across species
ContextSoaring birds depend on atmospheric uplifts and are sensitive to wind energy development. Predictive modelling is instrumental to forecast...

Performance and efficiency in leaf transport: unveiling the task allocation puzzle in Acromyrmex subterraneus
The performance of ant workers in a given task can be highly variable, generating a non-homogenous workload in the colony. However, there is no...

A low-cost wind tunnel for bird flight experiments
A blower-type wind tunnel for physiological bird flight experiments has been developed, constructed and evaluated. Since the birds to be investigated...

Global Prospects for Transition to Green Energy Generation in Saratov Oblast
AbstractThe global prospects for the transition to green energy generation in Saratov oblast are discussed. The literature data on the current...

Study of the Biological Dormancy of Aquatic Organisms in Open Space and Space Flight Conditions
AbstractIn outer space, ultraviolet and cosmic radiation, a wide range of high and low temperatures, altered gravity, electromagnetic fields, the...

Correlation between small-cell lung cancer serum protein/peptides determined by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and chemotherapy efficacy
BackgroundCurrently, no effective measures are available to predict the curative efficacy of small-cell lung cancer (SCLC) chemotherapy. We expect to...

Ethnography and ethnohistory support the efficiency of hunting through endurance running in humans
Humans have two features rare in mammals: our locomotor muscles are dominated by fatigue-resistant fibres and we effectively dissipate through...
