Saturniid and sphingid moths as novel models for the study of insect diversity and macroecology

Insects are the most speciose group of terrestrial organisms and are strongly affected by global environmental and climatic changes. They exhibit a remarkable variety of forms and life history trait combinations not represented among vertebrates and are responsible for many ecosystem services and disservices. Yet, our knowledge of their diversity and distributions, as well as our understanding of their evolution and diversification dynamics through space and time, remains fragmentary.
We have identified a group of herbivorous insects – the Saturniidae and Sphingidae, two sister families of moths – that represent an unparalleled insect model. This group comprises about 5000 species and has been thoroughly documented worldwide, through comprehensive DNA barcode libraries, hundreds of thousands of occurrence records in databases, and a broad documentation of their life histories. Thus, they offer for the first time an opportunity to study patterns of diversity and distribution at a global scale in insects, together with their underlying macroevolutionary processes.
Here we present the comprehensive database built by our research group and the different approaches – such as integrative taxonomy, biogeographical analyses, phylogenomics, analysis of traits and community ecology – that we combine to address key questions about the macroecological patterns and the evolutionary history of these moths.
This is the first time that such a holistic approach will have been applied to insects on a global scale. We expect that it will shed light on the processes governing the extant diversity of insects and help us understand how global changes will affect them, how they may or may not adapt to these changes, and how best we can act to conserve their species and preserve their roles in our ecosystems.

Gender equity at scientific events

Thirty years ago, a study highlighted the existence of gender inequity among speakers invited to present their research at a large, annual conference in Ecology and Evolution (Gurevitch 1988). Women were less frequently represented among the invited speakers as compared to contributed speakers, and far less likely to be invited to speak if there were no women among the symposium organizers. Over the last decade, a number of initiatives have been put forward in order to increase awareness and reduce implicit biases against female scientists (e.g. equal-opportunity guidelines, increased transparency in hiring, databases of female scientists, promotion of female role models). Nicolas Rode, Line Ugelvig and I investigated whether women today face fairer chances of being invited to speak at scientific events. We collected the number and gender of invited speakers and organizers from a large number of scientific events within the field of evolutionary biology ; 161 conferences, 67 congress symposia and 88 courses held in 2016—2017, and congress symposia held in the period 2001—2017. We used membership data from three large scientific societies as a reference current baseline of women in the field (i.e. constituting the pool from which potential invited speakers would be drawn). What did these data and analyses show ? To find out, come to the seminar !
