Social network position experiences more variable selection than weaponry in wild subpopulations of forked fungus beetles

Vincent Formica, Hannah Donald, Hannah Marti, Zhazira Irgebay &
1. The phenotypic expression and fitness consequences of behaviors that are exhibited during social interactions are especially sensitive to their local social context. This context-dependence is expected to generate more variation in the sign and magnitude of selection on social behavior than that experienced by static characters like morphology. Relatively few studies, however, have examined selection on behavioral traits in multiple populations. 2. We estimated sexual selection in the wild to determine if the strength...

Genetic diversity and connectivity of southern right whales (Eubalaena australis) found in the Brazil and Chile–Peru wintering grounds and the South Georgia (Islas Georgias del Sur) feeding ground

Freitas, Karina Groch, Pavel Hulva, Amy Kennedy, Russell Leaper, Mathew S. Leslie, Michael Moore, Larissa Oliviera … & Jennifer A Jackson
As species recover from exploitation, continued assessments of connectivity and population structure are warranted to provide information for conservation and management. This is particularly true in species with high dispersal capacity, such as migratory whales, where patterns of connectivity could change rapidly. Here we build on a previous long-term, large-scale collaboration on southern right whales (Eubalaena australis) to combine new (nnew) and published (npub) mitochondrial (mtDNA) and microsatellite genetic data from all major wintering grounds...

The genetic basis of coordinated plasticity across functional units in a Lake Malawi cichlid mapping population

Dina Navon, Paul Hatini, Lily Zogbaum & Craig Albertson
Adaptive radiations are often stereotypical, as populations repeatedly specialize along conserved environmental axes. Phenotypic plasticity may be similarly stereotypical, as individuals respond to environmental cues. These parallel patterns of variation, which are often consistent across traits, have led researchers to propose that plasticity can facilitate predictable patterns of evolution along environmental gradients. This “flexible stem” model of evolution raises questions about the genetic nature of plasticity, including: How complex is the genetic basis for plasticity?...
