Some microbial eukaryotes, such as the extremophilic red alga Galdieria sulphuraria, can live in hot, toxic metal-rich, acidic environments. To elucidate the underlying molecular mechanisms of adaptation, we sequenced the 13.7 Mb genome of G. sulphuraria. This alga shows an enormous metabolic flexibility, growing either photoautotrophically or heterotrophically on more than 50 carbon sources. Environmental adaptation seems to have been facilitated by horizontal gene transfer from various bacteria and archaea, often followed by gene family...

Data from: Demographic responses of a site-faithful and territorial predator to its fluctuating prey: long-tailed skuas and arctic lemmings

1. Environmental variability, through interannual variation in food availability or climatic variables, is usually detrimental to population growth. It can even select for constancy in key life-history traits, though some exceptions are known. Changes in the level of environmental variability are therefore important to predict population growth or life-history evolution. Recently, several cyclic vole and lemming populations have shown large dynamical changes, that might affect rodent predator demography or life histories. 2. Skuas constitute an...

Data from: Cuticular hydrocarbon divergence in the jewel wasp Nasonia: evolutionary shifts in chemical communication channels?

Jan Buellesbach, Juergen Gadau, Leo W. Beukeboom, Felix Echinger, Rhitoban Raychoudhury, Jack H. Werren & Thomas Schmitt
The evolution and maintenance of intraspecific communication channels constitutes a key feature of chemical signaling and sexual communication. However, how divergent chemical communication channels evolve while maintaining their integrity for both sender and receiver is poorly understood. In the present study, we compare male and female cuticular hydrocarbon (CHC) profiles in the jewel wasp genus Nasonia, analyze their chemical divergence, and investigate their role as species-specific sexual signaling cues. Males and females of all four...

Data from: Stepwise evolution of resistance to toxic cardenolides via genetic substitutions in the Na+/K+-ATPase of milkweed butterflies (Lepidoptera: Danaini)

Georg Petschenka, Steffi Fandrich, Nils Sander, Vera Wagschal, Michael Boppré & Susanne Dobler
Despite the monarch butterfly (Danaus plexippus) being famous for its adaptations to the defensive traits of its milkweed host plants, little is known about the macroevolution of these traits. Unlike most other animal species, monarchs are largely insensitive to cardenolides, since their target site, the sodium pump (Na+/K+-ATPase), has evolved amino acid substitutions which reduce cardenolide binding (so-called target site insensitivity, TSI). Since many, but not all, species of milkweed butterflies (Danaini) are associated with...
