The evolution of preferred male traits, female preference and the G matrix: “Toto, I’ve a feeling we’re not in Kansas anymore” Open
Female preference exerts selection on male traits. How such preferences affect male traits, how female preferences change and the genetic correlation between male traits and female preference were examined by an experiment in which females…
The Evolution of Female Preference, Male Traits and the G matrix: “Toto, I've a feeling we're not in Kansas anymore” Open
Female preference exerts selection pressure on male traits. This results in a complex interplay of phenotype and genotype. This complexity was examined by an experiment in which females were either mated to males they preferred (S lines) o…
Drift on holey landscapes as a dominant evolutionary process Open
An organism’s phenotype has been shaped by evolution but the specific processes have to be indirectly inferred for most species. For example, correlations among traits imply the historical action of correlated selection and, more generally…

This dataset contains all data and information used in the statistical analysis related ti the manuscript entitled “Evolutionary potential of thermal traits in Drosophila subobscura: is there coadaptation between thermal preference and the…

Evolutionary potential of thermal preference and heat tolerance in <i>Drosophila subobscura</i> Open
Evolutionary change of thermal traits (i.e., heat tolerance and behavioural thermoregulation) is one of the most important mechanisms exhibited by organisms to respond to global warming. However, the evolutionary potential of heat toleranc…
Four types of vibration behaviors in a mole cricket Open
Vibrational communication is known in some subterranean insects. Except for their use in sexual signaling, vibration behavior has rarely been reported. We report here four distinct types of substrate-based vibration behaviors in the mole c…
Adult social environment alters female reproductive investment in the cricket Gryllus firmus Open
The social environment surrounding an individual has the potential to affect not only external behaviors and actions but also internal physiological processes linked to fitness. We exposed adult female crickets to male calling song, which …
Synergism and Antagonism of Proximate Mechanisms Enable and Constrain the Response to Simultaneous Selection on Body Size and Development Time: An Empirical Test Using Experimental Evolution Open
Natural selection acts on multiple traits simultaneously. How mechanisms underlying such traits enable or constrain their response to simultaneous selection is poorly understood. We show how antagonism and synergism among three traits at t…
Co-occurrence of ecologically equivalent cryptic species of spider wasps Open
Many cryptic species have been discovered in various taxonomic groups based on molecular phylogenetic analyses and mating experiments. Some sympatric cryptic species share equivalent resources, which contradicts the competitive exclusion p…
