The Statistical Inevitability of Stability‐Diversity Relationships in Community Ecology
It is shown that for species diversity measures, stability will essentially always rise with species diversity because of the statistical averaging of the fluctuations in species' abundances, and that models of statistical averaging can serve as a useful baseline for predictions of community stability.
The Keystone-Species Concept in Ecology and ConservationManagement and policy must explicitly consider the complexity of interactions in natural systems
The term keystone species has enjoyed an enduring popularity in the ecological literature since its introduction by Robert T. Paine in 1969 and it is implicit that these species are exceptional, relative to the rest of the community, in their importance.
The need for integrative approaches to understand and conserve migratory ungulates.
It is found that for many species the disruption of migratory routes causes a rapid population collapse, and it is suggested that the migratory cycle should be evaluated in the context of seasonal population limitation.
Life Stage Simulation Analysis: Estimating Vital-Rate Effects on Population Growth for Conservation
We developed a simulation method, known as life-stage simulation analysis (LSA) to measure potential effects of uncertainty and variation in vital rates on population growth (λ) for purposes of

This study demonstrates that a combined physiological-demographic approach increases the ability to critically evaluate the potential impact of a predator on community structure and enables us to define underlying mechanisms of predator effects.
Longevity can buffer plant and animal populations against changing climatic variability.
The results suggest that problems associated with short-lived undesirable species may be exacerbated in regions where climate variability decreases, and that taxonomic affiliation has little power to explain sensitivity to increasing variability once longevity has been taken into account.
Demographic compensation and tipping points in climate-induced range shifts
It is shown that compensatory changes in demographic rates are buffering southern populations of two North American tundra plants against the negative effects of a warming climate, slowing their northward range shifts, but that this buffering is unlikely to continue indefinitely.
Modeling Population Viability for the Desert Tortoise in the Western Mojave Desert
It is found that the rate of population growth is most sensitive to the survival of large adult females and that improving survival of this size class to reputably "pristine" rates could reverse population declines; in contrast, large improvements in other vital rates will not, alone, reverse population decline.
