Survey of Lévy Flight-Based Metaheuristics for Optimization
Mathematics, 2022 Lévy flight is a random walk mechanism which can make large jumps at local locations with a high probability. The probability density distribution of Lévy flight was characterized by sharp peaks, asymmetry, and trailing.

Species traits affect phenological responses to climate change in a butterfly community
Scientific Reports, 2021 Diverse taxa have undergone phenological shifts in response to anthropogenic climate change. While such shifts generally follow predicted patterns, they are not uniform, and interspecific variation may have important ecological consequences. We evaluated

The flight apparatus of migratory and sedentary individuals of a partially migratory songbird species. [PDF]
PLoS ONE, 2012 Variations in the geometry of the external flight apparatus of birds are beneficial for different behaviors. Long-distance flight is less costly with more pointed wings and shorter tails; however these traits decrease maneuverability at low speeds ...
