Edaphic heterogeneity and the evolutionary trajectory of Amazonian plant communities. [PDF]

open access: yesEcol Evol, 2021
We investigated the phylogenetic structure of Amazonian fern and palm communities on edaphically distinct sites. We show that phylogenetic community structure varies along a soil base cation concentration gradient within non‐inundated Amazonian rain forests.

Seeing the wood despite the trees: Exploring human disturbance impact on plant diversity, community structure, and standing biomass in fragmented high Andean forests. [PDF]

open access: yesEcol Evol, 2021
High Andean forests play a key role in providing ecosystem services for neighboring urban settlements. Here, we aimed to identify and understand the effects of anthropogenic perturbations on diversity, composition, and structure of plant communities, as well as aboveground biomass in high Andean forest remnants in the hinterland of Bogotá.

Fern mycorrhizae do not respond to fertilization in a tropical montane forest. [PDF]

open access: yesPlant Environ Interact
In the present study, we assessed the root‐associated fungi of two epiphytic and two terrestrial fern species in a 15‐year fertilization experiment in the Ecuadorean Andes. We found no effect of fertilization on the diversity or abundance of the fungal assemblages associated with ferns.

Evolution of Repetitive Genomic Content and Gene Families Over Geo-Climatic Gradients in Brassicaceae. [PDF]

open access: yesEcol Evol
Along temperature gradients such as elevation and latitude, species typically occupy distinct ranges, and life at the extremes may come with adaptive and non‐adaptive genomic changes. In the Brassicaceae family, comparative genomics revealed that geo‐climatic factors strongly predict genome size and transposable element (TE) content, explaining up to ...

The relationship between chlorophyllous spores and mycorrhizal associations in ferns: evidence from an evolutionary approach

open access: yesAmerican Journal of Botany, Volume 109, Issue 12, Page 2068-2081, December 2022., 2022
Abstract Premise Approximately 14% of all fern species have physiologically active chlorophyllous spores that are much more short‐lived than the more common and dormant achlorophyllous spores. Most chlorophyllous‐spored species (70%) are epiphytes and account for almost 37% of all epiphytic ferns.

Patterns of ferns community assemblages in some Malaysian and Nigerian tropical forests

open access: yesEcology and Evolution, Volume 12, Issue 6, June 2022., 2022
The study assessed the patterns of ferns species richness (SR) and phylogenetic diversity (PD) in relation to the bioclimatic drivers in some Nigerian and Malaysian forests. Fern species richness and diversity is significantly higher in Malaysian forests than in Nigerian forests.

Directional changes over time in the species composition of tropical vascular epiphyte assemblages

open access: yesJournal of Ecology, Volume 110, Issue 3, Page 553-568, March 2022., 2022
Directionality in the temporal changes of epiphyte assemblages suggests that niche‐based mechanisms dominate these temporal changes. Host size over host identity is the most important environmental filter for epiphyte assemblages establishment. Tree Vectors Pack by Pixeden.com (https://www.freevector.com/trees‐illustrations). Abstract Understanding the

A target enrichment probe set for resolving the flagellate land plant tree of life

open access: yesApplications in Plant Sciences, Volume 9, Issue 1, January 2021., 2021
PREMISE New sequencing technologies facilitate the generation of large‐scale molecular data sets for constructing the plant tree of life. We describe a new probe set for target enrichment sequencing to generate nuclear sequence data to build phylogenetic trees with any flagellate land plants, including hornworts, liverworts, mosses, lycophytes, ferns ...

Insights into the evolutionary history and widespread occurrence of antheridiogen systems in ferns

open access: yesNew Phytologist, Volume 229, Issue 1, Page 607-619, January 2021., 2021
Summary Sex expression of homosporous ferns is controlled by multiple factors, one being the antheridiogen system. Antheridiogens are pheromones released by sexually mature female fern gametophytes, turning nearby asexual gametophytes precociously male. Nevertheless, not all species respond. It is still unknown how many fern species use antheridiogens,

Piacenzian Environmental Change and the Onset of Cool and Dry Conditions in Tropical South America

open access: yesPaleoceanography and Paleoclimatology, Volume 35, Issue 11, November 2020., 2020
Abstract The Piacenzian (3.60–2.58 Ma) covers the last stage of the Neogene just before the Earth's climate turned from relatively stable warm conditions to the cooler climate with high amplitude glacial‐interglacial oscillations of the Pleistocene.
