Title: " Transcriptome-based Exon Capture reveals cryptic diversity on the Hawaiian Tetragnatha adaptive radiation". 

Abstract:

In the Hawaiian Islands, the genus Tetragnatha has undergone a spectacular adaptive radiation. To study the effect of this dynamic volcanic landscape on the early stages of diversification I examined three close related species present in Maui Nui and the Big Island (T. brevignatha, T. waikamoi and T. macracnatha). I combined data from mitochondrial haplotypes with nuclear sequences. The later ones were obtained by applying a transcriptome-based Exon Capture. The sequences were analyzed using a low coverage approach.

As a complement to this population study, I did a preliminary phylogenetic reconstruction (COI) using field and museum specimens to study long distance dispersal across different Pacific islands. My current PostDoc project seeks to improve this phylogeny to answer questions about origin of colonization and diversification rates across different archipelagos.

 

We hope to see many of you at the seminar.

Sincerely,
Yoko Fujitomi
