Mainland diversification and recent island lineages in the reduviid genus Tapirocoris: an integrative taxonomic framework with four new species

Insect Science, EarlyView.
Using an integrative taxonomic framework that combines COI DNA barcodes, geometric morphometrics and phylogeography, we revise the assassin bug genus Tapirocoris and recover seven well‐supported species, including four newly described cryptic species.

Brokers, Collaborators and Knowledge Translators: Expanding the Role of Research Assistants in Geographic Research

Asia Pacific Viewpoint, EarlyView.
ABSTRACT While ‘local’ research assistants (RA) often play a key role in knowledge production in fieldwork‐based disciplines like geography, their role and agency often remain silenced. This paper brings together scholarship in feminist geography and critical development studies to reposition RAs as brokers, collaborators, and knowledge translators.

Synthesis of pyranonaphthoquinone antibiotics involving the phthalide annulation strategy

, 2006
The synthesis of the pyranonaphthoquinone antibiotic pentalongin was performed using the phthalide annulation strategy. Annulation of the cyanophthalide onto 6H-pyran-3-one resulted in a hongconin analogue, which upon further elaboration was converted ...
