Lattice Brownian bees with cooperative reproduction: steady states, collapse, and spreading
Ohad Vilk, Baruch Meerson
We extend the ``Brownian bees'' model of Berestycki et al.\ (2021, 2022) to cooperative reproduction, , of a population of symmetric random walkers with removal,…
Emergent population dynamics of random walkers with cooperative reproduction and spatial selection
Ohad Vilk, Baruch Meerson
We extend the branching Brownian motions model of population invasion to higher-order asexual reproduction. Increasing reproduction order leads to qualitative changes: invasion…
Strong anomalous diffusion for free-ranging birds
Ohad Vilk, Motti Charter, Sivan Toledo +2
Diffusion and anomalous diffusion are widely observed and used to study movement across organisms, resulting in extensive use of the mean and mean-squared displacement (MSD). Howev…
Non-Markovian Rock-Paper-Scissors games
Ohad Vilk, Mauro Mobilia, Michael Assaf
There is mounting evidence that species interactions often involve long-term memory, with highly-varying waiting times between successive events and long-range temporal correlation…
Ergodicity breaking in area-restricted search of avian predators
Ohad Vilk, Yotam Orchan, Motti Charter +4
Quantifying and comparing patterns of dynamical ecological systems require averaging over measurable quantities. For example, to infer variation in movement and behavior, metrics s…
Extinction risk of a Metapopulation under the Allee Effect
Ohad Vilk, Michael Assaf
We study the extinction risk of a fragmented population residing on a network of patches coupled by migration, where the local patch dynamics include the Allee effect. We show that…
Population Extinction under Bursty Reproduction in a Time Modulated Environment
Ohad Vilk, Michael Assaf
In recent years non-demographic variability has been shown to greatly affect dynamics of stochastic populations. For example, non-demographic noise in the form of a bursty reproduc…
