How two Afrotropical endemics made two cosmopolitan human commensals: the , palaeogeographic riddleulation sizes dramatically. We stress the good match between the geographical ranges of . and ., and the mismatch between . and this rubiaceous plant, yet assumed to be its restricted host-plant. We suggest that the ecological status of the four species of the . complex may represent four steps of t

Comparative life histories and ecophysiology of , and ,, or subtropical climate. This is presumably due to the fact that most comparisons have been done at a single, standard temperature of 25°C. Comparative studies should be undertaken, spanning the thermal ranges of the two species, and the phenotypic plasticity of ecophysiological traits should now be

Comparative analysis of morphological traits among , and ,: genetic variability, clines and phenoty polynomial adjustments. For a given trait, the reaction norms of the two species are similar in their shape, although some significant differences may be observed..Within each species, significant differences are also observed between geographic populations: reaction norms are not parallel and the

Cardioplegia

Relations between cuticular hydrocarbon (HC) polymorphism, resistance against desiccation and breeds an increase in 25C compounds and a decrease in 23C compounds, but the opposite effect in . A mathematical model of biosynthesis, based on kinetics of elongation and decarboxylation enzymes, suggests that a simple variation of the efficiency of an elongation enzyme may account for the differences o

A mutation in , that lengthens the circadian period of locomotor activity,ing circadian period. This phenotype was mapped to the X chromosome, close to the . gene, but there was also a significant effect of a modifying autosomal locus or loci. It seems remarkable that such a mutant phenotype should be discovered in a screen of chimeric Thr-Gly regions.

Sperm size evolution in ,: inter- and intraspecific analysis,fferentially to abiotic local factors. ., in contrast to ., shows a clinal pattern in sperm size associated with drought. We discussed this pattern in relation to the potential role of sperm length in the ongoing process of non-random mating and incipient sympatric speciation observed in this locali
