Data from: Asexual queen succession mediates an accelerated colony life cycle in the termite Silvestritermes minutusRomain Fougeyrollas, Jan Křivánek, Virginie Roy, Klára Dolejšová, Sophie Frechault, Yves Roisin, Robert Hanus & David Sillam-Dussès
Mixed modes of reproduction, combining sexual processes with thelytokous parthenogenesis, occur in all major clades of social insects. In several species of termites, queens maximize their genetic input into nondispersing replacement queens through parthenogenesis, while maintaining genetically diverse sterile offspring and dispersing reproductives via sexual reproduction. This so-called asexual queen succession (AQS) has multiple independent origins and its presumed advantages are diverse as well, ranging from multiplication of colony reproductive potential to extension of its...
Data from: Asexual queen succession in the higher termite Embiratermes neotenicusRomain Fougeyrollas, Klára Dolejšová, David Sillam-Dussès, Virginie Roy, Chantal Poteaux, Robert Hanus & Yves Roisin
Asexual queen succession (AQS), in which workers, soldiers and dispersing reproductives are produced sexually while numerous non-dispersing queens arise through thelytokous parthenogenesis, has recently been described in three species of lower termites of the genus Reticulitermes. Here, we show that AQS is not an oddity restricted to a single genus of lower termites, but a more widespread strategy occurring also in the most advanced termite group, the higher termites (Termitidae). We analysed the genetic structure...
Post-eclosion temperature effects on insect cuticular hydrocarbon profilesSubhash Rajpurohit, Vladimír Vrkoslav, Robert Hanus, Allen Gibbs, Josef Cvačka & Paul Schmidt
The insect cuticle is the interface between internal homeostasis and the often harsh external environment. Cuticular hydrocarbons (CHCs) are key constituents of this hard cuticle and are associated with a variety of functions including stress response and communication. CHC production and deposition on the insect cuticle vary among natural populations and are affected by developmental temperature; however, little is known about CHC plasticity in response to the environment experienced following eclosion, during which time the...
Anion Binding by Bambusuril Probed in the Gas Phase and in SolutionÁgnes Révész, Detlef Schröder, Jan Svec, Michaela Wimmerová & Vladimir Sindelar
Electrospray ionization mass spectrometry (ESI-MS) is used to probe the binding of small anions to the macrocycle of bambusuril. For the halide ions, the experimental patterns suggest F– < Cl– < Br– < I–, which is consistent with the order of anion binding found in the condensed phase. Parallel equilibrium studies in the condensed phase establish the association constants of halide anions and bambusuril in mixed solvents. A detailed analysis of the mass spectrometric data...
