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.
Fishing‐induced evolution of growth: concepts, mechanisms and the empirical evidence
TLDR
The selection pressures on growth and the resultant evolution of growth from a mechanistic viewpoint are explored and the prevailing expectation that fishing-induced evolution should always lead to slower growth is challenged.
Managing Evolving Fish Stocks
TLDR
Life-history theory predicts that increased mortality generally favors evolution toward earlier sexual maturation at smaller size and elevated reproductive effort, and these evolutionary changes are unfolding on decadal time scales—much faster than previously thought.
Ecology: Managing Evolving Fish Stocks
Evolutionary impact assessment is a framework for quantifying the effects of harvest-induced evolution on the utility generated by fish stocks.
Lyapunov functions for Lotka–Volterra predator–prey models with optimal foraging behavior
Abstract. The theory of optimal foraging predicts abrupt changes in consumer behavior which lead to discontinuities in the functional response. Therefore population dynamical models with optimal…
Evolutionary regime shifts in age and size at maturation of exploited fish stocks
TLDR
It is suggested that stepwise decreases in maturation age can be used as early warnings of upcoming evolutionary changes, and should inspire timely restrictions of fisheries.
Linking the Allee Effect, Sexual Reproduction, and Temperature‐Dependent Sex Determination Via Spatial Dynamics
TLDR
A spatially explicit, two‐sex, individual‐based model (IBM) and a derived spatially homogeneous model (SHM) to describe the Allee effect due to scarcity of mating possibilities at low population sizes or densities and how the position of the extinction boundary depends on population demography and adopted mate search strategies is examined.
Does Sex-Selective Predation Stabilize or Destabilize Predator-Prey Dynamics?
TLDR
It is shown that long-term effects of sex-selective predation depend on the interplay of predation bias and prey mating system, and the observed skew towards male-biased predation might reflect, in addition to sexual selection, the evolutionary history of predator-prey interactions.
Evolutionary impact assessment: accounting for evolutionary consequences of fishing in an ecosystem approach to fisheries management
TLDR
The evolutionary impact assessment (EvoIA) is described as a structured approach for assessing the evolutionary consequences of fishing and evaluating the predicted evolutionary outcomes of alternative management options.
How predator functional responses and Allee effects in prey affect the paradox of enrichment and population collapses.
TLDR
It is shown that abrupt and deterministic system collapses not preceded by fluctuating predator-prey dynamics occur for sufficiently steep type III functional responses and strong Allee effects (with unstable lower equilibrium in prey dynamics).
