Density dependent environments can select for extremes of body size

T. Coulson, A. Felmy, T. Potter, G. Passoni, R. A. Montgomery, J.-M. Gaillard, P. J. Hudson, J. Travis, R. D. Bassar, S. D. Tuljapurkar, D. Marshall, S. M. Clegg

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

J. M. Anaya-Rojas, R. D. Bassar, T. Potter, A. Blanchette, S. Callahan, N. Framstead, D. M. Reznick, J. Travis

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

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

A. Felmy, D. N. Reznick, J. Travis, T. Potter, T. Coulson

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.

Rapid genomic convergent evolution in experimental populations of Trinidadian guppies (Poecilia reticulata)

M. J. van der Zee, J. R. Whiting, J. R. Paris, R. D. Bassar, J. Travis, D. Weigel, D. N. Reznick, B. A. Fraser

This study identifies candidate loci for convergent evolution in guppies adapted to low predation environments using genome-wide sequencing and a novel multivariate approach.

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

A. Felmy, J. Leips, J. Travis

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.

PREDICTING COEXISTENCE IN SPECIES WITH CONTINUOUS ONTOGENETIC NICHE SHIFTS AND COMPETITIVE ASYMMETRY

R. D. Bassar, J. Travis, T. Coulson

This paper develops a framework using Integral Projection Models to predict coexistence in species with continuous ontogenetic niche shifts and competitive asymmetry, showing multiple routes to coexistence based on niche shifts and competitive dynamics.
