Biogeography of body size in terrestrial isopods (Crustacea: Oniscidea)
(2016)This study tries to unveil the contribution of climatic shift in shaping the extreme body size diversity in terrestrial isopods (Oniscidea). Trying to explain size variation at an interspecific level, we test five hypotheses: ... -
Life history evolution in a globally invading tephritid: Patterns of survival and reproduction in medflies from six world regions
(2009)Comparisons among populations from different localities represent an important tool in the study of evolution. Medflies have colonized many temperate and tropical areas all over the world during the last few centuries. In ... -
Lifespan of a Ceratitis fruit fly increases with higher altitude
(2010)Variation in lifespan may be linked to geographic factors. Although latitudinal variation in lifespan has been studied for a number of species, altitude variation has received much less attention, particularly in insects. ... -
Local adaptation, intrapopulation adult emergence patterns, sex and prolonged diapause regulate the rate of postwinter development in pupae of the European cherry fruit fly
(2017)We used the European cherry fruit fly, Rhagoletis cerasi (Diptera: Tephritidae), an oligophagous, univoltine species that overwinters as pupae, to determine the geographical variation in postwinter development of pupae ...
