The dynamics of a grassland ecosystem: botanical equilibrium in the park grass experiment
TL;DR: No regular or irregular cycles of component biomass operating between years were detected and it is inferred that populations were regulated by processes operating within individual years.
Journal ArticleDOI
Uncertainty and variability in demography and population growth: a hierarchical approach
TL;DR: A hierarchical approach is adapted to the problem of estimating population growth rates and their uncertainties when individuals vary and that variability cannot be assigned to specific causes, which shows that population growth models that rely on standard propagation of estimation error but ignore variability among individuals can misrepresent uncertainties in ways that erode credibility.

Indirect Mutualism: Variations on a Theme by Stephen Levine
TL;DR: This paper attempts to extend the work of Levine (1976) in the context of the basic summary provided by Vandermeer and Boucher (1978), thereby providing a theoretical framework for the concept of "indirect mutualism" and suggesting that this form of interaction is likely to be extremely important in community organization, at least at some trophic levels.

TL;DR: Both the strength of total density dependence in the life history and the magnitude of environmental stochasticity, including transient fluctuations in age structure, increase with generation time, indicating that the relationships between demographic and life-history traits in birds translate into distinct population dynamical patterns that are apparent only on a scale of generations.
Journal ArticleDOI
Antagonistic coevolution over productivity gradients.
TL;DR: A quantitative coevolutionary model for a predator‐prey interaction is developed and predicts that generalist strains dominate in productive areas of the prey, whereas specialists prevail in marginal habitats.
