Why the architecture of environmental fluctuation matters for fitness

The paper shows how non-random structures in environmental fluctuations affect fitness, using a demographic model to compare different fluctuation types.

Density dependent environments can select for extremes of body size

The paper develops size-structured models to explore how density dependence influences body size evolution, showing that gigantism or dwarfism depends on population maturity proportions and developmental trajectories.

Selfing-outcrossing as a gradient, not a dichotomy: propensity for selfing varies within a population of hermaphroditic animals

The paper quantifies individual variation in selfing propensity in a hermaphroditic snail and finds that selfing propensities are partially heritable and independent of environmental factors.

An ecological explanation for hyperallometric scaling of reproduction

The paper explains reproductive hyperallometry by showing that individual differences in resource assimilation drive disproportionate reproductive output with body size in wild populations, but not in lab settings with controlled resources.

Life histories as mosaics: plastic and genetic components differ among traits that underpin life-history strategies

The paper tests whether genetic and environmental factors differ in their influence on life-history traits across high- and low-predation guppy ecotypes, finding variation in trait control by genetics and environment.

Ancestral ecological regime shapes reaction to food limitation in the Least Killifish, Heterandria formosa

The study shows that fish from high-density populations better handle food limitation than those from low-density populations, with survival to maturity being significantly affected by population x food-level interactions.

Dynamic Price and Breeder's equations for variable environments

The paper extends the Breeder's and Price equations to dynamic environments by incorporating time-dependent selection differentials and heritabilities from structured population models.
