There is growing concern over tipping points arising in ecosystems because of the crossing of environmental thresholds. Tipping points lead to abrupt and possibly irreversible shifts between alternative ecosystem states, potentially incurring high societal costs. Trait variation in populations is central to the biotic feedbacks that maintain alternative ecosystem states, as they govern the responses of populations to environmental change that could stabilize or destabilize ecosystem states… 

Fast environmental change and eco-evolutionary feedbacks can drive regime shifts in ecosystems before tipping points are crossed

TLDR
It is shown that fast environmental change can trigger regime shifts before environmental stress exceeds a tipping point in evolving ecological systems, suggesting that management measures to prevent rate-induced regime shifts should focus on mitigating the effects of environmental change and protecting phenotypic diversity in ecosystems.

Global impacts of invasive species on the tipping points of shallow lakes

TLDR
It is found that certain INNS drive significant changes in the abundance of key taxa and conditions that govern the balance of alternative equilibria in shallow lakes, which provides guidance for managers of invaded shallow lake ecosystems.

Tipping point realized in cod fishery

TLDR
It is argued that ignorance of non-linear resource dynamics has caused the demise of an economically and culturally important social-ecological system which calls for better adaptation of fisheries systems to climate change.

Tipping points and multiple drivers in changing aquatic ecosystems: A review of experimental studies

Natural ecosystems are experiencing unprecedented rates of change due to anthropogenic activities and global change, leading to either gradual changes in a given response or tipping points. While the

TLDR
Understanding tipping points using an eco-evolutionary perspective to better forecast abrupt transitions in ecological systems is argued for.

Adaptive Evolution Can Both Prevent Ecosystem Collapse and Delay Ecosystem Recovery

TLDR
This work finds that adaptive evolution of macrophytes can increase ecosystem resilience by shifting the critical threshold, which marks the transition from a clear-water state to a turbid-waterState to a higher level of environmental stress, and implies that restoration could be more effective when implemented early enough after a transition occurs and before organisms adapt to the alternative state.

Ectomycorrhizas and tipping points in forest ecosystems.

TLDR
Tipping point theory is applied to forests, including their belowground component, focusing on EM fungi, and a link environmental thresholds for EM fungi with nutrient imbalances in forest trees is explored, and major positive feedback mechanisms are proposed to understand, address and predict forest ecosystem tipping points.

Evolutionary emergence of alternative stable states in shallow lakes

Ecosystems under stress may respond abruptly and irreversibly through tipping points. Although much is explored on the mechanisms that affect tipping points and alternative stable states, little is

Evolutionary rescue can prevent rate-induced tipping

TLDR
This work study how indirect evolutionary rescue - due to the rapid evolution of a predator’s trait - can save a prey population from the rate-induced collapse and concludes that the maintenance of biodiversity requires a deceleration of the anthropogenic degradation of natural habitats.

Collapse and rescue of evolutionary food webs under global warming

TLDR
This work exposes simulated trophic networks of co-evolving consumers to warming under different evolutionary scenarios, which allows us to assess the effect of evolution on diversity maintenance and investigates how the evolution of body mass and feeding preference affects coexistence within a simplified consumer-resource module.

An evolutionary tipping point in a changing environment

TLDR
It is shown how evolutionary tipping points produce evolutionary hysteresis, creating extinction debts, and there is no bound on the rate of evolution and persistence is determined by the critical rate of environmental change at which populations cease to grow.

Resilience indicators: prospects and limitations for early warnings of regime shifts

In the vicinity of tipping points—or more precisely bifurcation points—ecosystems recover slowly from small perturbations. Such slowness may be interpreted as a sign of low resilience in the sense

Response diversity determines the resilience of ecosystems to environmental change

TLDR
A conceptual model is provided to describe how loss of response diversity may cause ecosystem degradation through decreased ecosystem resilience, and how response diversity contributes to functional compensation and to spatio‐temporal complementarity among species, leading to long‐term maintenance of ecosystem multifunctionality.

Phenotypic diversity and ecosystem functioning in changing environments: A theoretical framework

TLDR
It is suggested that approaches developed for quantitative genetics can be extended to ecosystem functioning by modeling the means and variances of phenotypes within a group of species, and that phenotypic variance within functional groups is linearly related to their ability to respond to environmental changes.

Partitioning the Effects of Eco-Evolutionary Feedbacks on Community Stability

TLDR
This work provides a general framework for determining the effects of eco-evolutionary feedbacks on stability in communities with an arbitrary number of interacting species and evolving traits for when evolution is slow and fast, and describes how these feedbacks lead to stable communities that would be unstable in the absence of the feedbacks.

The sudden collapse of pollinator communities.

TLDR
It is shown that pollinator populations may collapse suddenly once drivers of pollinator decline reach a critical point, and that the scale and nature of critical transitions is likely to be influenced by the architecture of mutualistic networks.

Fishing-induced life-history changes degrade and destabilize harvested ecosystems

TLDR
It is shown how fishing may both increase fluctuations in fish abundances and also, when accompanied by decreasing body size of adults, further decrease fish abundance and increase temporal variability of fishes’ food resources and their ecosystem.

TLDR
Evidence that the global ecosystem as a whole is approaching a planetary-scale critical transition as a result of human influence is reviewed, highlighting the need to improve biological forecasting by detecting early warning signs of critical transitions.

When do shifts in trait dynamics precede population declines?

TLDR
This study explores the ecological and evolutionary constraints under which a fitness-related trait can be used as an early warning signal of an impending population decline and shows that under medium-to-slow rate of environmental change, shifts in trait value can precede population decline.
