BACKGROUND Much of ecological theory and the understanding of ecological systems has
been based on the idea that the observed states and dynamics of ecological systems can be …

This paper discusses the recent progress in understanding the properties of transient
dynamics in complex ecological systems. Predicting long-term trends as well as sudden …

Allee effects are (broadly) defined as a decline in individual fitness at low population size or
density. They can result in critical population thresholds below which populations crash to …

Cooperation is a ubiquitous behavior in many biological systems and is well-known for
promoting Allee effects. However, few studies have paid attention to mechanisms inducing …

Humans have moved organisms around the world for centuries but it is only relatively
recently that invasion ecology has grown into a mainstream research field. This book …

Understanding the dynamics of small populations is obviously important for declining or rare
species but is also particularly important for invading species. The Allee effect, where fitness …

The realization that complex systems such as ecological communities can collapse or shift
regimes suddenly and without rapid external forcing poses a serious challenge to our …

In the face of global biodiversity declines, predicting the fate of biological systems is a key
goal in ecology. One popular approach is the search for early warning signals (EWS s) …

Catastrophic regime shifts in complex natural systems may be averted through advanced
detection. Recent work has provided a proof-of-principle that many systems approaching a …

In this research article, a three-species food chain model with Allee effect and additional
food is proposed and analyzed. The Allee effect and additional food are introduced to the …
