Long-term conservation effects of protected areas in stochastic population dynamics

This study develops stochastic models to analyze the long-term conservation effects of protected areas, finding that reduced mortality, high site preference, and immigration rates lower variability in population size.

On the spillover effect and optimal size of marine reserves for sustainable fishing yields

This paper investigates optimal marine reserve sizes for sustainable fishing yields, finding that an optimal size exists when pre-reserve fishing mortality exceeds fMSY, and that high fishing mortality reduces the requirement for a moderate migration rate.

Optimal reproductive phenology under size-dependent cannibalism

The paper develops a game-theoretic model to show that size-dependent cannibalism can drive earlier breeding phenology than optimal environmental conditions.

A geometric approach to scaling individual distributions to macroecological patterns

The paper develops a geometric framework to derive macroecological patterns from individual distribution data, recovering known patterns and providing new insights into their relationships.

A Theory For Ecological Survey Methods To Map Individual Distributions

The paper develops a theory for designing ecological surveys to map individual distributions by considering spatial scales and detectability, showing tradeoffs between mapping resolution and coverage.

Spatially Explicit Approach To Population Abundance Estimation In Field Surveys

The paper develops a spatially explicit method for population abundance estimation in field surveys, showing how accuracy depends on ecological factors and sampling design.
