Extrapolating demography with climate, proximity and phylogeny: approach with caution [PDF]
, 2016 Plant population responses are key to understanding the effects of threats such as climate change and invasions. However, we lack demographic data for most species, and the data we have are often geographically aggregated.

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.

Plant Species Biology, Volume 40, Issue 6, Page 572-583, November 2025.Spatial distribution pattern were studied for Ceratozamia fuscoviridis, an endangered species in Mexico, based on Ripley's K t and K 12 analysis. Clumped spatial distribution patters was found in individuals of all populations, suggesting low interaction with predators/dispersers and/or evidence of suitable microsites for cycads.

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.

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 ...
