Rpadrino: an R package to access and use PADRINO, an open access database of Integral Projection Models

Rpadrino provides an R package to access and use PADRINO, a database of Integral Projection Models, enabling users to reconstruct and analyze published IPMs.

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.

The evolution of size-dependent competitive interactions promotes species coexistence

The paper tests how size-dependent competitive interactions affect species coexistence by comparing allopatric and sympatric populations of guppies and killifish.

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.

Substantial intraspecific variation in energy budgets: biology or artefact?

The paper shows that DEB model parameters vary within species due to data types and biological differences, challenging interspecies comparisons but allowing valid comparisons when data types are accounted for.

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.
