The complete chloroplast genome of Microcycas calocoma (Miq.) A. DC. (Zamiaceae, Cycadales) and evolution in Cycadales [PDF]

PeerJ, 2020
Cycadales is an extant group of seed plants occurring in subtropical and tropical regions comprising putatively three families and 10 genera. At least one complete plastid genome sequence has been reported for all of the 10 genera except Microcycas ...

Reconciling fossils with phylogenies reveals the origin and macroevolutionary processes explaining the global cycad biodiversity

New Phytologist, Volume 240, Issue 4, Page 1616-1635, November 2023., 2023
Summary The determinants of biodiversity patterns can be understood using macroevolutionary analyses. The integration of fossils into phylogenies offers a deeper understanding of processes underlying biodiversity patterns in deep time. Cycadales are considered a relict of a once more diverse and globally distributed group but are restricted to low ...

Estimating clade‐specific diversification rates and palaeodiversity dynamics from reconstructed phylogenies

Methods in Ecology and Evolution, Volume 14, Issue 10, Page 2575-2591, October 2023., 2023
Abstract Understanding palaeodiversity dynamics through time and space is a central goal of macroevolution. Estimating palaeodiversity dynamics has been historically addressed with fossil data because it directly reflects the past variations of biodiversity.

Cycad phylogeny predicts host plant use of Eumaeus butterflies

Ecology and Evolution, Volume 13, Issue 4, April 2023., 2023
A case of tight evolution between Eumaeus herbivorous butterflies and cycads, pointing to the generality of correlated evolution and phylogenetic tracking in plant–herbivore interactions across seed plants. Abstract Eumaeus butterflies are obligate herbivores of Zamia, the most diverse neotropical genus of cycads.

Seed predation and potential seed dispersers of the endemic, narrowly distributed Ceratozamia norstogii (Zamiaceae)

, 2022
Reproductive ecology in Ceratozamia has been little studied. In particular, very little is known about seed dispersal. Here we report the observation of seed predators and potential seed dispersers of the endemic to Mexico and narrowly distributed ...

Pollen morphology of the Megamexican cycads reveals the potential of morphometrics to identify cycad genera

Botan‪ical Sciences, 2020
Background: Although pollen morphology has always been an important tool in plant systematics, the possibility of distinguishing between related taxa is still debated. A difficult case is the cycads, where their morphology and small size is very similar.

Experimental evidence that leaf litter decomposability and flammability are decoupled across gymnosperm species

Journal of Ecology, Volume 111, Issue 4, Page 761-772, April 2023., 2023
This is the first study to comprehensively show that litter decomposability and litter bed flammability parameters are decoupled across a wide range of species. This decoupling originates from the former depending mostly on ‘size and shape spectrum’ (SSS) traits and the latter on ‘plant economics spectrum’ (PES) traits and those trait spectra being ...

Mega‐sized pericentromeric blocks of simple telomeric repeats and their variants reveal patterns of chromosome evolution in ancient Cycadales genomes

The Plant Journal, Volume 112, Issue 3, Page 646-663, November 2022., 2022
Significance Statement Telomeric sequences, typically found at chromosome ends, play an essential role in genome integrity. We studied their abundance across land plants and observe large blocks of telomeric repeats at centromere positions, particularly on telocentric chromosomes of cycads.

The RadOrgMiner pipeline: Automated genotyping of organellar loci from RADseq data

Methods in Ecology and Evolution, Volume 13, Issue 9, Page 1962-1975, September 2022., 2022
Abstract Different versions of Restriction‐site‐Associated DNA sequencing (RADseq) have become powerful and popular tools in molecular ecology. Although RADseq datasets are generally regarded as representative of the nuclear genome, reduced representation genomic libraries may also sample the organellar (i.e.

A new species of Ceratozamia (Zamiaceae) from Chiapas, Mexico [PDF]

Botanical Journal of the Linnean Society, 2001
Ceratozamia zoquorum sp. nov. from the northern mountains of Chiapas, Mexico, is described and illustrated. It has affinities with C. miqueliana Wendl. from Veracruz, but differs in leaf, male female cone and trunk morphology.
