Unraveling Biogeographic Boundaries Within the Sierra Madre Oriental, México: An Endemicity Analysis Using a Taxonomically Diverse Dataset. [PDF]

Ecol Evol
We provide boundaries of the Sierra Madre Oriental in Mexico through a multi‐taxa endemicity analysis. ABSTRACT The Sierra Madre Oriental (SMO) is a significant mountain range and one of Mexico's 14 biogeographical provinces. Its delimitation has been debated.

Ceratozamia aurantiaca (Zamiaceae): A New Cycad Species from the Northern Rainforests of Oaxaca, Mexico

Taxonomy, 2021
Ceratozamia aurantiaca, a new cycad species from Oaxaca, Mexico, is described. The new species is endemic to lowland karst tropical rainforests of the northern mountains (Sierra Norte region). This species is related to C. subroseophylla and C.

Analysis of the extranucleolar ribonucleoprotein particles of Cycas revoluta Thunb. (Cycadaceae) and Ceratozamia mexicana Brongn. (Zamiaceae)

Botan‪ical Sciences, 2022
Background: Nuclear ribonucleoprotein particles play a key role in RNA processing and in the gene expression pathway. Interchromatin granules (GICs) involved in the metabolism of pre-messenger RNA (pre-mRNA) were described in Allium cepa and ...

Evolutionary trends of reproductive phenotype in Cycadales: an analysis of morphological evolution in Ceratozamia. [PDF]

Ann Bot
Abstract Background and Aims The size and shape of reproductive structures is especially relevant in evolution because these characters are directly related to the capacity for pollination and seed dispersal, a process that plays a basic role in evolutionary patterns.

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.

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 ...

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.
