Single-species models of the Allee effect: extinction boundaries, sex ratios and mate encounters.
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.
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.
Fishing‐induced evolution of growth: concepts, mechanisms and the empirical evidence
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
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.

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.
How predator functional responses and Allee effects in prey affect the paradox of enrichment and population collapses.
Modelling mate-finding Allee effects and populations dynamics, with applications in pest control
In this paper, we review how mate-finding Allee effects enter population dynamical models that consider both sexes, highlight possible limitations of the more widely used “one-sex” models, and…
Evolutionary impact assessment: accounting for evolutionary consequences of fishing in an ecosystem approach to fisheries management
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.
Can fisheries-induced evolution shift reference points for fisheries management?
Biological reference points are important tools for fisheries management. Reference points are not static, but may change when a population's environment or the population itself changes.…
Linking the Allee Effect, Sexual Reproduction, and Temperature‐Dependent Sex Determination Via Spatial Dynamics
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.
