Species delimitation of the Cycas segmentifida complex (Cycadaceae) resolved by phylogenetic and distance analyses of molecular data

Frontiers in Plant Science, 2016
The Cycas segmentifida complex consists of eight species whose distributions overlap in a narrow region in Southwest China. These eight taxa are also morphologically similar and are difficult to be distinguished.

Biotic Threats to Cycas micronesica Continue to Expand to Complicate Conservation Decisions

Insects, 2020
Invasions of non-native species can threaten native biodiversity, and island ecosystems are ideal for studying these phenomena. In this article, first, we report on the invasive species that combine to threaten the island cycad Cycas micronesica by ...

Most young leaves pale in comparison to mature leaves: delayed greening is neither binary nor tropical

Ecography, Volume 2025, Issue 9, September 2025.
Delayed greening, the phenomenon in which expanding leaves appear red, blue or pale green due to low chlorophyll content, has long intrigued ecologists. However, little is known about what type of species are most likely to delay greening or which environmental conditions are associated with delayed greening.

Adventitious rooting of mature Cycas micronesica K.D. Hill (Cycadales: Cycadaceae) tree stems reveals moderate success for salvage of an endangered cycad

Journal of Threatened Taxa, 2017
Mature Cycas micronesica trees were among the forest trees that were destined to be removed from a 2012 construction site in northern Guam.  Forty-nine of these trees were cut at the base and transported to nursery conditions to determine if adventitious
