Larval Crowding Did Not Enhance Adult Migration Propensity in Spodoptera frugiperda
Reproduction and flight are two major adaptive strategies to cope with environmental stress in migratory insects. However, research on density-mediated flight and reproduction in the global migratory agricultural pest Spodoptera frugiperda is lacking. In

Robust flight-to-gate assignment with landside capacity constraints [PDF]
At the interface between airport airside and landside operations, the assignment of flights to gates is key to ensure efficient operations and a high quality of service for passengers. We propose a mixed-integer linear program for an integrated flight-to-gate assignment that considers both airside as well as landside constraints on the capabilities of ...

A trade-off between the capacity for flight and reproduction has been documented extensively in wing polymorphic female insects, thereby supporting the possible fitness gain due to flightlessness.

Oxygen Dependence of Flight Performance in Ageing Drosophila melanogaster
Similar to humans, insects lose their physical and physiological capacities with age, which makes them a convenient study system for human ageing. Although insects have an efficient oxygen-transport system, we know little about how their flight capacity ...

Limits to load-lifting performance in a passerine bird: the effects of intraspecific variation in morphological and kinematic parameters [PDF]
Although more massive flight muscles along with larger wings, higher wingbeat frequencies and greater stroke amplitudes enhance force and power production in flapping flight, the extent to which these parameters may be correlated with other morphological

Resolution of a paradox: Hummingbird flight at high elevation does not come without a cost [PDF]
Flight at high elevation is energetically demanding because of parallel reductions in air density and oxygen availability. The hovering flight of hummingbirds is one of the most energetically expensive forms of animal locomotion, but hummingbirds are ...

Mechanisms and Consequences of Partial Migration in Insects
Partial migration, where a proportion of a population migrates, while other individuals remain resident, is widespread across most migratory lineages.

Multi-airport system flight slot optimization method based on absolute fairness
With the rapid development of the civil aviation industry, the number of flights has increased rapidly. However, the availability of flight slot resources remains limited, and how to allocate flight slot resources effectively has been a hot research ...
