Beetles (Coleoptera) in cones of cycads (Cycadales) of the northern hemisphere: diversity and evolution [PDF]

, 2020
Three groups of beetles inhabit cones of cycads (Cycadales) in the northern hemisphere and are believed to be involved in their pollination. The primitive weevil subtribe Allocorynina (Coleoptera: Belidae) is restricted to the New World cycad genera ...

Cycads in vitro

Plant Tissue Culture and Biotechnology, 2015
The Cycadales are a group of botanical and evolutionary importance; however, many species face the threat of extinction due to poaching and habitat destruction. The current investigation reviews previous work on in vitro production of cycads, which holds great potential for mass production and germplasm conservation of these unique plants ...

The Environmental Cost of Development in a Biodiversity Hotspot

Conservation Letters, Volume 19, Issue 5, September/October 2026.
ABSTRACT Global infrastructure development is reshaping tropical environments, yet its biodiversity consequences remain poorly quantified. We assess the ecological implications of Mexico's Interoceanic Corridor of the Isthmus of Tehuantepec (CIIT), a transcontinental megaproject linking transportation between the Atlantic and Pacific oceans across a ...

Can stable isotopes and radiocarbon dating provide a forensic solution for curbing illegal harvesting of threatened cycads? [PDF]

, 2014
Cycads in South Africa are facing an extinction crisis due to the illegal extraction of plants from the wild. Proving wild origin of suspect ex situ cycads to the satisfaction of a court of law is difficult, limiting law enforcement efforts.

Changes in the Carotenoids of Zamia dressleri Leaves during Development

Plants
It has been observed that the leaves of some Zamia species undergo a kind of “reverse ripening”; that is, they change from their original brown color to green during development.

Revisiting the nomenclature of Carludovica microcephala, type species of Dicranopygium (Cyclanthaceae)

TAXON, Volume 75, Issue 4, August 2026.
Abstract The name Carludovica microcephala, basionym of the type species of Dicranopygium (Cyclanthaceae), has long been attributed to J.D. Hooker (1892), based on plants cultivated at the Royal Botanic Gardens, Kew. A reassessment of nineteenth‐century horticultural literature shows that the name had already been validly published 35 years earlier, in

Chemical Analysis of Cycads from Varied Environment [PDF]

, 2019
Cycads are one of the most primitive plants (ancestral species), that are believed to have existed even during the Mesozoic Era, the dinosaurs period. They have evolved over millions of years, in varied climate and habitat, and yet there are some feature

Evidence for an ancient whole genome duplication in the cycad lineage.

PLoS ONE, 2017
Contrary to the many whole genome duplication events recorded for angiosperms (flowering plants), whole genome duplications in gymnosperms (non-flowering seed plants) seem to be much rarer.

Ecological niches and biogeography of nitrogen‐fixing plants in Europe

Plant Biology, Volume 28, Issue 5, Page 1349-1360, August 2026.
Despite sharing N fixation as a common trait, European legume and actinorhizal plant lineages occupy strikingly divergent ecological niches shaped by their evolutionary histories and physiological adaptations. Advanced symbiont control allows IRLC legumes to expand into northern, mesic regions, while non‐IRLC legumes are more common in Mediterranean ...
