Arms race of physical defences: Hooked trichomes of Macaranga ant-plants kill lycaenid caterpillars, but one specialist has a counter-defence

Ritabrata Roy Chowdhury, T. Ulmar Grafe, Faizah Metali, Walter Federle

The paper shows that hooked trichomes on Macaranga trees defend against most Arhopala caterpillars, but one species, A. amphimuta, can bypass this defense, indicating an evolutionary arms race between plants and herbivores.

Sex-determination and sex chromosomes are shared across the radiation of dioecious Nepenthes pitcher plants

Mathias Scharmann, T. Ulmar Grafe, Faizah Metali, Alex Widmer

The paper identifies XY sex-determination systems in three Nepenthes species and develops a statistical method to detect sex-specific genomic regions in wild populations.
