Genome size evolution and phenotypic correlates in the poison frog family Dendrobatidae

This study estimates genome sizes for 32 poison frog species and finds gradual evolution with correlations to body size and reproductive traits, but no link to chemical defense evolution.

Divergence, gene flow and the origin of leapfrog geographic distributions: The history of color pattern variation in Phyllobates poison-dart frogs

This study examines the role of divergence and gene flow in shaping leapfrog geographic distributions of color patterns in Phyllobates poison frogs, finding evidence for gene flow between neighboring populations but not over long distances.

Does batrachotoxin autoresistance co-evolve with toxicity in Phyllobates poison-dart frogs?

The paper investigates whether autoresistance to batrachotoxin co-evolves with toxicity in Phyllobates frogs, finding no evidence of a correlation between the two traits.

Mutations in the pantothenate kinase of Plasmodium falciparum confer diverse sensitivity profiles to antiplasmodial pantothenate analogues

The paper identifies mutations in Plasmodium falciparum pantothenate kinase genes that confer resistance to pantothenate analogues and reveal different mechanisms of action for these compounds.
