We consider the dynamics of a three-species system incorporating the Allee Effect, focussing on its influence on the emergence of extreme events in the system. First we find that under Allee effect the regular periodic dynamics changes to chaotic. Further, we find that the system exhibits unbounded growth in the vegetation population after a critical value of the Allee parameter. The most significant finding is the observation of a critical Allee parameter beyond which the probability of… Expand

Influence of Allee Effect on Extreme Events in Coupled Three Species Systems
TLDR
Noise suppresses the unbounded vegetation growth that was induced by a combination of Allee effect and coupling, and it is demonstrated that noise mitigates extreme events in all three populations, and beyond a noise level the system does not observe any extreme events at all. Expand

Advent of extreme events in predator populations
TLDR
The results indicate how occurrences of extremely large predator populations can emerge in coupled population dynamics, and in a more general context they suggest a generic class of deterministic nonlinear systems that can naturally exhibit extreme events. Expand
Emergence of extreme events in networks of parametrically coupled chaotic populations.
TLDR
A new mechanism in coupled chaotic systems that naturally yield extreme events in both time and space is suggested, when the range of coupling is sufficiently large and when enough neighbouring populations influence the growth rate of a population. Expand
Allee effect in prey’s growth reduces the dynamical complexity in prey-predator model with generalist predator
Abstract Prey-predator models with Allee effect have great importance in the context of ecology. Allee effect refers to a positive relationship between population density and per capita growth rate.Expand
Pushed beyond the brink: Allee effects, environmental stochasticity, and extinction
TLDR
It is illustrated counter-intuitively that environmental fluctuations can increase the probability of persistence when populations are initially at low densities, and can cause asymptotic extinction of populations experiencing intermediatepredation rates despite conditional persistence occurring at higher predation rates.

Balance of Interactions Determines Optimal Survival in Multi-Species Communities
TLDR
The network transitions from a completely extinct system to one where all nodes are active, as the mean interaction strength goes from negative to positive, with the transition getting sharper for increasing C and decreasing σ, and the total population displays distinct non-monotonic scaling behaviour with respect to the product μC.

TLDR
It is shown that the cost of rarity increases the stability of (the stable) fixed point in a broad class of one-dimensional difference equation systems, including the host-microparasite model. Expand
Complex dynamics and phase synchronization in spatially extended ecological systems
TLDR
This work examines the synchronization of complex population oscillations in networks of model communities and in natural systems, where phenomena such as unusual ‘4- and 10-year cycle’ of wildlife are often found. Expand
Single-species models of the Allee effect: extinction boundaries, sex ratios and mate encounters.
TLDR
Individual-based models seem to be most capable of explaining mechanisms leading to the Allee effect, and may give better predictions of extinction thresholds than heuristic models but require specific information and are data intensive. Expand
An ecological perspective on extreme climatic events: a synthetic definition and framework to guide future research
TLDR
A synthetic definition of an extreme climatic event (ECE) is proposed that includes ‘extremeness’ in both the driver and the response and a mechanistic framework for ECEs is used to identify priorities for future research that will enable ecologists to more fully assess the ecological consequences of climate extremes for ecosystem structure and function today and in a future world where their frequency and intensity are expected to increase.

TLDR
This work develops a macroscopic description of the evolution of a random weighted network with complex nonlinear dynamics at each node in terms of the statistical features of the subnetwork of active nodes with similar asymptotic characteristics. Expand
