AxiomsA time scale is a special measure chain that can unify continuous and discrete spaces, enabling the construction of integrable equations. In this paper, with the Lax operator generated by the displacement operator, N-dimensional lattice integrable ...

Journal of Mathematical Analysis and Applications, 2003 In this paper, the author defines the Riemann and Lebesgue integrals (more precisely, the Riemann and Lebesgue \(\Delta\)-integrals and \(\nabla\)-integrals) on time scales and studies their properties and relationship. In particular, the author presents results concerning the lower and upper Darboux sums, the Riemann sums, the Riemann and Lebesgue ...

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders
Population Ecology, EarlyView.We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...

The Lie Brackets on Time Scales [PDF]
Abstract and Applied Analysis, 2012 The Lie derivative, which has a wide range of application in physics and geometry, is trying to be examined on time scales. Firstly, nabla Lie bracket is defined on two‐dimensional time scales. Secondly, the nabla Lie multiplication and some properties are given on the time scales.

Population Ecology, EarlyView.Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size
