Fossils of an endangered, endemic, giant dipterocarp species open a historical portal into Borneo's vanishing rainforests. [PDF]

Am J Bot
Abstract Premise Asia's wet tropical forests face a severe biodiversity crisis, but few fossils record their evolutionary history. We recently discovered in situ cuticles on fossil leaves, attributed to the giant rainforest tree Dryobalanops of the iconic Dipterocarpaceae family, from the Plio‐Pleistocene of Brunei Darussalam (northern Borneo ...

Inflorescence and floral morphology of Haptanthus hazlettii (Buxaceae, Buxales)

Botanical Journal of the Linnean Society, 2015
The enigmatic Central American tree Haptanthus hazlettii has recently been placed in Buxaceae (Buxales) by molecular evidence. However, Haptanthus appears morphologically to be fundamentally different from other Buxales in having pluriovular carpels with parietal placentation and reduced male reproductive units of an obscure morphological nature.

Host-mediated, cross-generational intraspecific competition in a herbivore species

Peer Community Journal, 2021
Conspecific insect herbivores co-occurring on the same host plant interact both directly through interference competition and indirectly through exploitative competition, plant-mediated interactions and enemy-mediated interactions. However, the situation
