Detecting Causality in Complex Ecosystems
A new method, based on nonlinear state space reconstruction, that can distinguish causality from correlation is introduced, and extends to nonseparable weakly connected dynamic systems (cases not covered by the current Granger causality paradigm).
Sustaining Fisheries Yields Over Evolutionary Time Scales
This work subjected populations of an exploited fish to large, small, or random size-selective harvest of adults over four generations, finding that large-harvested populations initially produced the highest catch but quickly evolved a lower yield than controls.
Spatial and temporal scales of adaptive divergence in marine fishes and the implications for conservation
Evidence that selection is a potent evolutionary force capable of sustaining adaptive divergence on contemporary time scales is summarized and the idea that contemporary selective processes can cause fine-scale spatial and temporal divergence underscores the need for a new emphasis on Darwinian fishery science.
Maladaptive changes in multiple traits caused by fishing: impediments to population recovery.
This work empirically modelled the recovery of overharvested fish populations by subjecting populations of a harvested marine fish, the Atlantic silverside, to experimental size-biased fishing regimes over five generations and then measured correlated responses across multiple traits.
The global contribution of forage fish to marine fisheries and ecosystems
Forage fish play a pivotal role in marine ecosystems and economies worldwide by sustaining many predators and fisheries directly and indirectly. We estimate global forage fish contributions to marine…

From simple to complex, these examples demonstrate the feasibility of quantifying, predicting and understanding state-dependent, nonlinear interactions as they occur in situ and in real time—a requirement for managing resources in a nonlinear, non-equilibrium world.

Populations have an intrinsic capacity to recover genetically from harmful evolutionary changes caused by fishing, even without extrinsic factors that reverse the selection gradient, and are predicted to recover in about 12 generations.
Thermal legacies: transgenerational effects of temperature on growth in a vertebrate.
It is provided the first evidence for thermal TGP in a vertebrate: given sufficient time, sheepshead minnows adaptively program their offspring for maximal growth at the present temperature.
THEORY AND EMPIRICAL EVIDENCE

Using Akaike's information criterion, it is shown that swimming performance decreases with the square of growth rate, providing the first demonstration of a nonlinear cost of growth.
A Life‐History Perspective on Short‐ and Long‐Term Consequences of Compensatory Growth
It is shown that a life‐history model incorporating the mortality consequences of both size and damage provides a framework for understanding compensatory growth and is used to classify physiological and life-history characteristics for which CG is predicted to be the optimal response to deprivation.
