Divergence time analyses suggest a Miocene origin of the narrow Amazonian endemic rheophytic Ceratolejeunea temnantha (Spruce) Reiner-Drehwald (Porellales, Lejeuneaceae)

open access: yesBryophyte Diversity and Evolution, 2018
The recent rediscovery of the rheophytic endemic Ceratolejeunea temnantha ~130 years after its original description, on the upper Rio Negro in the Brazilian Amazon, has enabled the assessment of its enigmatic phylogenetic position, estimates of its divergence time, and updates on its distribution and potential habitat threats.

Spore germination, early development and some notes on the effects of in vitro culture medium on Frullania ericoides (Nees) Mont. (Frullaniaceae, Marchantiophyta) [PDF]

open access: yes, 2017
In bryophytes, establishment can occur by a sexual or asexual process, but the production of spores enables colonization of a wider range of habitats and substrates than can asexual propagules.

One species or at least eight? Delimitation and distribution of Frullania tamarisci (L.) Dumort. s. l. (Jungermanniopsida, Porellales) inferred from nuclear and chloroplast DNA markers

open access: yesMolecular Phylogenetics and Evolution, 2010
Frullania tamarisci is usually regarded as a polymorphic, holarctic-Asian liverwort species with four allopatric subspecies [subsp. asagrayana, moniliata, nisquallensis and tamarisci]. This hypothesis is examined using a dataset including sequences of the nuclear internal transcribed spacer region and the plastid trnL-trnF and atpB-rbcL regions of 88 ...

Exploring the impact of fossil constraints on the divergence time estimates of derived liverworts [PDF]

open access: yes, 2013
In this study, we evaluate the impact of fossil assignments and different models of calibration on divergence time estimates carried out as Bayesian analyses.

Molecular Species Delimitation in the Racomitrium canescens Complex (Grimmiaceae) and Implications for DNA Barcoding of Species Complexes in Mosses [PDF]

open access: yes, 2015
In bryophytes a morphological species concept is still most commonly employed, but delimitation of closely related species based on morphological characters is often difficult.

MAINTENANCE OF SEXUALLY DIMORPHIC PATTERNS OF GROWTH AND REPRODUCTION IN MARCHANTIA INFLEXA [PDF]

open access: yes, 2004
Sexual dimorphism in life history traits may influence the distribution of the sexes,population sex ratios, the maintenance of sex in populations, and the evolutionarypotential of a species.

Size doesn't matter-recircumscription of Microlejeunea (Lejeuneaceae, Porellales) based on molecular and morphological evidence

open access: yes, 2018
Phylogenetic analyses of a three marker dataset of Lejeuneaceae (chloroplast genome rbcL gene and trnL-F region, and nuclear ribosomal ITS1-5.8S-ITS2 region) resolve the "Lejeunea complex" in three main lineages assigned here to Harpalejeunea, Lejeunea and Microlejeunea. The taxa Harpalejeunea fischeri, H. filicuspis, H.
