This paper analyzes a number of relatively general models of predator‐prey adaptation and coadaptation. The motivation behind this work is, in part, to evaluate the “race analogy” that has been applied in analyzing predator‐prey coevolution. The models are based on the assumption that increased investment in predation‐related adaptations must be paid for by decreased adaptation to some other factor. Increased investment in predation‐related adaptations by the prey lowers the predator's… 
Evolutionary responses of foraging-related traits in unstable predator–prey systems
  • P. Abrams

The evolutionary responses of predators to prey and of prey to predators are analysed using models for the dynamics of a quantitative trait that determines the capture rate of prey by an average
Effects of adaptive predatory and anti-predator behaviour in a two-prey—one-predator system
TLDR
These results imply that observations of the relationship between prey density and predation rate cannot be used to infer the nature of the behavioural indirect effect between prey that share a predator.
The Fossil Record of Predator-Prey Arms Races: Coevolution and Escalation Hypotheses
TLDR
A geographic view of species interactions and the processes driving their evolution may lead to a more diverse array of testable hypotheses on how predator-prey systems evolve and what constraints interactions impose on the evolution of organisms.
The Evolution of Predator-Prey Interactions: Theory and Evidence
▪ Abstract Recent theories regarding the evolution of predator-prey interactions is reviewed. This includes theory about the dynamics and stability of both populations and traits, as well as theory
Adaptive foraging by predators predator-prey cycles as a cause of
TLDR
This paper investigates predator-prey models in which there are explicit dynamics for the rate of adaptive change, and finds that the remaining conditions required for cycles are surprisingly insensitive to the nature of the adaptive process.
Predators that Benefit Prey and Prey that Harm Predators: Unusual Effects of Interacting Foraging Adaptation
  • P. Abrams
  • Environmental Science
    The American Naturalist
  • 1992
TLDR
This article explores models of four-species food chains in which two species adaptively balance food intake and risk of predation, and shows first that such interacting behaviors will often reach a stable equilibrium, and then derived differential equations to describe population dynamics when the behaviors remain close to their optima.
The Evolution of Traits Affecting Resource Acquisition and Predator Vulnerability: Character Displacement under Real and Apparent Competition
TLDR
This article investigates some simple models of the evolutionary interaction between two prey species that share a common resource and a common predator to determine whether examples of character displacement previously interpreted as responses to competition for resources might also reflect responses to altered predation risks in sympatry.
Adaptive foraging by predators as a cause of predator-prey cycles
TLDR
This paper investigates predator-prey models in which there are explicit dynamics for the rate of adaptive change, and finds that the remaining conditions required for cycles are surprisingly insensitive to the nature of the adaptive process.
Character Shifts of Prey Species That Share Predators
  • P. Abrams
  • Environmental Science

  • 2000
TLDR
This article uses several models to explore how the antipredator adaptations of a focal prey species are likely to evolve following the introduction of a second prey species that shares one or more of the same predator species.
Evolution and Adaptation of Anti-predation Response of Prey in a Two-Patchy Environment
  • Ao Li, X. Zou
  • Mathematics
    Bulletin of mathematical biology
  • 2021
TLDR
A patch model is formulated to investigate the aforementioned fear effect which is indirect, in contrast to the predation as a direct effect, of the predator on the prey population, implying the existence of an optimal anti-predation response level.

On the Evolution of Energy Balance in Some Exploiter‐Victim Systems
TLDR
It is argued that density—dependent genetic feedback has the potential to regulate the amount of energy taken by a predator population from the prey or host population, and support the idea that prey evolution can enhance predator stability and lead to a balanced supply—demand economy between predator and prey.

TLDR
This paper analyzes several descriptive models of exploitation and shows that the evolutionary process does not result in a randomly prudent interaction, and produces a degree of prudence which is at the same time predestined for each predator.
The Coevolution and Stability of Competing Species
TLDR
For the cases considered, the co-evolved divergence of the consumers leads to greater global stability of the consumer community even though it has negligible effect on the local Lyapunov stability.
Arms races between and within species

TLDR
The arms race concept is suggested to help to resolve three long-standing questions in evolutionary theory: one lineage may drive the other to extinction, one may reach an optimum, thereby preventing the other from doing so, and both sides may reach a mutual local optimum.

Results suggest that variation in the proportion of time spent foraging can provide an alternative mechanism for traditional functional response forms of predators.
