Substantial intraspecific variation in energy budgets: biology or artefact?

Prolonged action potentials in HCM-derived iPSC--biology or artefact?

Trees and/or networks to display intraspecific DNA sequence variation?

Phylogenetic trees and networks are both used in the scientific literature to display DNA sequence variation at the intraspecific level. Should we rather use trees or networks? I argue that the process of inferring the most parsimonious genealogical relationships among a set of DNA sequences should be dissociated from the problem of displaying this information in a graph. A network graph is pro...

Intraspecific variation in social organization by genetic variation, developmental plasticity, social flexibility or entirely extrinsic factors.

Previously, it was widely believed that each species has a specific social organization, but we know now that many species show intraspecific variation in their social organization. Four different processes can lead to intraspecific variation in social organization: (i) genetic variation between individuals owing to local adaptation (between populations) or evolutionarily stable strategies with...

Intraspecific nucleotide variation in Anopheles gambiae: new insights into the biology of malaria vectors.

The Anopheles gambiae genome sequence, together with the recent development of molecular tools for genome-wide analysis, promises new insights into the biology of the malaria vector. These insights should help define the best possible breakdown point for interrupting transmission in the mosquito vector. A survey of the intraspecific nucleotide diversity in coding regions of three different mosq...
