Threats to cycad biocultural heritage in the Amami Islands, Japan
Plant Species Biology, Volume 40, Issue 4, Page 292-310, July 2025.The central point we seek to frame in this article is that the increasing infestations of cycad aulacaspis scale in the Amami guntō existentially threaten not only the islands' sotetsu but rather entire cultural systems and natural ecologies that have developed around these plants.

Body size and evolutionary rate analyses reveal complex evolutionary history of Alvarezsauria
Cladistics, Volume 41, Issue 1, Page 135-155, February 2025.Abstract Some of the smallest examples of dinosaurian body size are from alvarezsaurians, an enigmatic group of maniraptoran coelurosaurians with a peculiar combination of anatomical features unique among theropods. Despite the large number of alvarezsaurian species described worldwide and the increased understanding this has provided, the body‐size ...

The need for a socioecological harm reduction approach to reduce illegal wildlife trade
Conservation Biology, Volume 38, Issue 5, October 2024.Abstract The burgeoning illegal trade in succulents in southern Africa presents a critical conservation and social development challenge. Drawing parallels with the trajectory of the response to rhinoceros poaching, we considered the consequences of conservation law enforcement measures, particularly the militarization of antipoaching efforts.

American Journal of Botany, Volume 111, Issue 9, September 2024.Abstract Premise The Cenozoic Macquarie Harbour Formation (MHF) hosts one of the oldest and southernmost post‐Cretaceous fossil plant assemblages in Australia. Coinciding with the Early Eocene Climatic Optimum (EECO) and predating the breakup of Australia from Antarctica, it offers critical data to study the diversity and extent of the Austral Polar ...

The evolutionary history of Coleoptera (Insecta) in the late Palaeozoic and the Mesozoic
Systematic Entomology, Volume 49, Issue 3, Page 355-388, July 2024.Structural transformations of the elytra and abdomen played a major role in the early beetle evolution in the Permian. Polyphaga appear late in the fossil record, with only a few fossils of Elateriformia in the Late Triassic. Several factors were involved in the enormous diversification of beetles in the Cretaceous but evolutionary interactions with ...
