The classic work of Paul Buchner in the first half of the 20th century established the common
occurrence of symbiotic associations between microbes and animals, often a fungus …

Over a thousand Drosophila species have radiated onto a wide range of feeding and
breeding sites. These radiations involve adaptations for locating, accepting, and growing in …

High‐throughput transcriptome studies are breaking new ground to investigate the
responses that organisms deploy in alternative environments. Nevertheless, much remains …

Background The chance to compare patterns of differential gene expression in related
ecologically distinct species can be particularly fruitful to investigate the genetics of …

Background Insights into the genetic capacities of species to adapt to future climate change
can be gained by using comparative genomic and transcriptomic data to reconstruct the …

Highlights•Insect transcriptome expression has revealed responses to use of different plant
hosts.•Host plant adaptation involves detoxification and metabolism of secondary …

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 …

Drosophila buzzatii and D. koepferae are sibling cactophilic species. The former breeds
primarily on prickly pears (genus Opuntia) whereas the latter breeds on columnar cacti of the …

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 …

Habitat avoidance is an anti-parasite behaviour exhibited by at-risk hosts that can minimize
exposure to parasites. Because environments are often heterogeneous, host decision …
