Turing-Turing Bifurcation Analysis and Normal Form in a Predator-Prey Model with Predator-Taxis and Prey Refuge
This paper investigates a predator-prey reaction-diffusion model incorporating predator-taxis and a prey refuge mechanism, subject to homogeneous Neumann boundary conditions. Our primary focus is the analysis of codimension-two Turing-Turing bifurcation and the calculation of its associated normal form for this model. Firstly, employing the maximum principle and Amann's theorem, we rigorously establish the local existence and uniqueness of classical solutions. Secondly, utilizing linear stabili…

Kambodscha: Rettet den Prey-Lang-Wald!
Er ist der größte und wichtigste Tieflandregenwald des Landes. Aufgrund seines Artenreichtums hat die kambodschanische Regierung Prey Lang 2016 unter Schutz gestellt – und vergibt dennoch Konzessionen an Landwirtschaft und Industrie. Unterstützen Sie die Forderung der Bevölkerung, die Umweltgesetze zu respektieren.

When I'm outside, I like to keep moving. I'd be a nice morsel for a bird of prey.

Auditory cortex cares about when a sound turns off, and more than preceding auditory processing stages do.
“… neural representations after the sound offset show a three-fold increase in sound encoding accuracy in the cortex relative to subcortical areas.”
This makes sense to me for any mammal that might be prey (like mice, or humans), that negative changes in sounds might be as informative as positive changes in sounds.

Chase-and-Run and Chirality in Nonlocal Models of Pattern Formation
Chase-and-run dynamics, in which one population pursues another that flees from it, are found throughout nature, from predator-prey interactions in ecosystems to the collective motion of cells during development. Intriguingly, in many of these systems, the movement is not straight; instead, 'runners' veer off at an angle from their pursuers. This angled movement often exhibits a consistent left-right asymmetry, known as lateralisation or chirality. Inspired by such phenomena in zebrafish skin p…

Periodicity in delayed self-regulation is a predator-prey process
We unify two different periodicity mechanisms: delayed self-regulation and planar predator-prey feedback. We consider scalar delay differential equations $\dot x(t) = rf(x(t), x(t - 1))$ where $f$ is monotone in the delayed component. Due to a Poincaré--Bendixson theorem for monotone delayed feedback systems, the typical global dynamics present periodic orbits as the delay parameter $r$ increases. In this article, we show that, as we vary the delay, each connected component of periodic orbits …

I am quite confident that there are more trojan containers somewhere in Russia. Russia rotated their bombers around, so Ukraine couldn't have known for a long time where they are. So they had to prepare more containers in case the wanted prey is on other airports. Expecting more Bavovna 💥

A Comprehensive Survey on Bio-Inspired Algorithms: Taxonomy, Applications, and Future Directions
Bio-inspired algorithms (BIAs) utilize natural processes such as evolution, swarm behavior, foraging, and plant growth to solve complex, nonlinear, high-dimensional optimization problems. This survey categorizes BIAs into eight groups: evolutionary, swarm intelligence, physics-inspired, ecosystem and plant-based, predator-prey, neural-inspired, human-inspired, and hybrid approaches, and reviews their core principles, strengths, and limitations. We illustrate the usage of these algorithms in mac…

Lotka-Volterra-type kinetic equations for interacting species
In this work, we examine a kinetic framework for modeling the time evolution of size distribution densities of two populations governed by predator-prey interactions. The model builds upon the classical Boltzmann-type equations, where the dynamics arise from elementary binary interactions between the populations. The model uniquely incorporates a linear redistribution operator to quantify the birth rates in both populations, inspired by wealth redistribution operators. We prove that, under a su…
