Species delimitation, genetic diversity and population historical dynamics of Cycas diannanensis (Cycadaceae) occurring sympatrically in the Red River region of China

Frontiers in Plant Science, 2015
Delimitating species boundaries could be of critical importance when evaluating the species’ evolving process and providing guidelines for conservation genetics.

An Updated DNA Barcoding Tool for Aloe Vera and Related CITES‐Regulated Species

Conservation Letters, Volume 18, Issue 4, July/August 2025.
ABSTRACT DNA barcoding has revolutionized the identification of illegally traded material of endangered species as it overcomes the lack of resolution encountered with morphological identification. Nonetheless, in recently evolved and highly diverse clades, such as the relatives of Aloe vera, the lack of interspecific sequence variation in standardized

Investigating the Genetic Diversity, Population Differentiation and Population Dynamics of Cycas segmentifida (Cycadaceae) Endemic to Southwest China by Multiple Molecular Markers

Frontiers in Plant Science, 2017
Climate change, species dispersal ability and habitat fragmentation are major factors influencing species distribution and genetic diversity, especially for the range-restricted and threatened taxa. Here, using four sequences of chloroplast DNAs (cpDNAs),

Population Differentiation and Demographic History of the Cycas taiwaniana Complex (Cycadaceae) Endemic to South China as Indicated by DNA Sequences and Microsatellite Markers

Frontiers in Genetics, 2019
Historical geology, climatic oscillations, and seed dispersal capabilities are thought to influence the population dynamics and genetics of plants, especially for distribution-restricted and threatened species.

Notes on the Natural History of Cycas seemannii (Cycadaceae) [PDF]

The South Pacific Journal of Natural and Applied Sciences, 2001
Cycas seemannii occurs in several habitats in Vanuatu, New Caledonia, Fiji and Tonga, but is mostly coastal. Growth rates are about 5-15cm.yr-1 and sex ratios observed were almost neutral. Mechanisms to survive in adverse environments are discussed.

Pest categorisation of Pyrrhoderma noxium

EFSA Journal, Volume 22, Issue 3, March 2024.
Abstract Following the commodity risk assessment of bonsai plants (Pinus parviflora grafted on Pinus thunbergii) from China performed by EFSA, the EFSA Plant Health Panel performed a pest categorisation of Pyrrhoderma noxium, a clearly defined plant pathogenic basidiomycete fungus of the order Hymenochaetales and the family Hymenochaetaceae.

Nesting behaviour of the Baya Weaver bird, Ploceus philippinus (Ploceidae) and the life-cycle of the Plains Cupid butterfly, Chilades pandava (Lycaenidae) with the red-listed Cycas spheric and C. beddomei (Cycadaceae)

Journal of Threatened Taxa, 2009
The Baya Weaver bird, Ploceus philippinus utilizes the well developed leaves of Cycas sphaerica for nest construction and offspring production. It constructs nest on the leaf tips of this species; the nest material used is exclusively Dendrocalamus ...
