A greedy nearest-neighbor approach to quantify site revisitation: comparing two sympatric raven species
Bar Ashkenazi, Miguel de Guinea, Michael Assaf +1
A central challenge in movement ecology is to describe ecologically meaningful residence sites from raw tracking data due to heterogeneous sampling frequency and uncertain site bou…
Outbreak-size distributions under fluctuating rates
Jason Hindes, Luis Mier-y-Teran-Romero, Ira B. Schwartz +1
We study the effect of noisy infection (contact) and recovery rates on the distribution of outbreak sizes in the stochastic SIR model. The rates are modeled as Ornstein-Uhlenbeck p…
Evolutionary Dynamics in a Varying Environment: Continuous versus Discrete Noise
Ami Taitelbaum, Robert West, Mauro Mobilia +1
Environmental variations can significantly influence how populations compete for resources, and hence shape their evolution. Here, we study population dynamics subject to a fluctua…
Extreme outbreak dynamics in epidemic models
Jason Hindes, Michael Assaf, Ira B. Schwartz
Motivated by recent epidemic outbreaks, including those of COVID-19, we solve the canonical problem of calculating the dynamics and likelihood of extensive outbreaks in a populatio…
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…
Population Dynamics in a Changing Environment: Random versus Periodic Switching
Ami Taitelbaum, Robert West, Michael Assaf +1
Environmental changes greatly influence the evolution of populations. Here, we study the dynamics of a population of two strains, one growing slightly faster than the other, compet…
