A review of non‐native scale insects (Hemiptera: Coccomorpha: Coccoidea) of Australia and the challenges in maintaining current and accurate pest lists

Austral Entomology, Volume 65, Issue 1, February 2026.
Abstract Over 870 species of scale insects, also called coccoids (infraorder Coccomorpha), have been recorded from Australia. Here, we systematically review literature, databases and collections to provide a revised assessment of non‐native species to Australia, for which we confirm those species that are introduced and extant in Australia (including ...

Comprehensive tree assessments for prioritising conservation action in Mesoamerica

PLANTS, PEOPLE, PLANET, Volume 7, Issue 6, Page 1813-1823, November 2025.
Tree species are of ecological and social importance globally. Mesoamerica has a diverse tree flora, and the region has experienced major changes in natural habitats due to human activities. In this study, for the first time, we assessed the conservation status of the region's tree species and found that 46% of trees in the region are at risk of ...

Ceratozamia alba (Zamiaceae): A new cycad species from the Selva El Ocote Biosphere Reserve in Chiapas, Mexico

Phytotaxa
Ceratozamia alba sp. nov., a new cycad species from the Selva El Ocote Biosphere Reserve in northern Chiapas, Mexico, is described and compared to its congeners. Our earlier observations led us to think that these populations belonged to C.

G-fibers and Florin ring-like structures in Dioon (Zamiaceae)

Botan‪ical Sciences, 2016
Cuticle information and epidermal characters have great potential in systematic studies.  However, micromorphology and anatomical studies on cycads are relatively scarce in comparison to similar studies on other gymnosperms.

A first characterization of the leaflet endophytic prokaryotic community in Dioon cycads

Plant Species Biology, Volume 40, Issue 6, Page 547-555, November 2025.
This study presents the first characterization of leaflet endophytic prokaryotic communities in Mexican cycads of the genus Dioon. Using 16S rRNA metabarcoding, we describe the composition and diversity of foliar bacterial communities across species and biogeographic regions, highlighting patterns potentially shaped by environmental conditions.

Progress in the study of dioecy in Mexican cycad species and its implications for conservation

Plant Species Biology, Volume 40, Issue 6, Page 556-571, November 2025.
Cycads are endangered dioecious plants of great ornamental value that have a long period of sexual maturity. Therefore, it is crucial to have methods for early sex determination that can help to develop effective strategies for their conservation. Abstract Dioecy is a system of sexual reproduction in plants, characterized by the spatial separation of ...
