Host plant shifts in herbivorous insects often involve facing new environments that may
speed up the evolution of oviposition behavior, performance-related traits, morphology, and …

Host shifts cause drastic consequences on fitness in cactophilic species of Drosophila. It has
been argued that changes in the nutritional values accompanying host shifts may elicit these …

The host-plant environment of phytophagous insects directly affects various aspects of an
insect's life cycle. Interestingly, relatively few insect groups have specialized in the …

Increasing evidence from multiple animal systems suggests that genital evolution and
diversification are driven by rapid and strong evolutionary forces. Particularly, the …

Drosophila buzzatii and Drosophila koepferae are sibling species with marked ecological
differences related to their patterns of host exploitation. D. buzzatii is a polyphagous species …

The cactus-yeast-Drosophila system is a model system in evolutionary biology, and the
participating saprotrophic microorganisms represent one of the most thoroughly studied …

Drosophila buzzatii and D. koepferae coexist in the arid lands of southern South America
and exploit different types of cactus as breeding hosts. The former prefers to lay eggs on the …

The cactophilic flies Drosophila buzzatii and Drosophila koepferae are generally each
associated with a different host cactus, although resource sharing can occur in regions of …

Closely related species often differ in the signals involved in sexual communication and
mate recognition. Determining the factors influencing signal quality (ie signal's content and …

Abstract Changes in the environmental conditions experienced by naturally occurring
populations are frequently accompanied by changes in adaptive traits allowing the organism …
