Introduction
My current research covers three main topics, (i) exploring the population genomic structure of the lichen species Cladonia stellaris in eastern north America, (ii) investigating the microbial community associated to reindeer lichens, as well as the factor driving the composition of this community, and (iii) recovering, including viruses, the metagenome-assembled genomes from lichens.

Article
A worldwide taxonomic revision of the species belonging to the moss genus Chionoloma Dixon (Pottiaceae) is here presented. Our work is based on the morphological analysis of more than 2600 specimens deposited in different herbaria or collected during field trips. A total of 131 names were found and their nomenclatural types were examined, resulting...

The southern Appalachian (SA) is one of the most biodiversity−rich areas in North America and has been considered a refugium for many disjunct plant species, from the last glacial period to the present. Our study focuses on the SA clonal hornwort, Nothoceros aenigmaticus J. C. Villarreal & K. D. McFarland. This hornwort was described from North Car...

Premise: Lichens are one of the main structural components of plant communities in the North American boreal biome. They play a pivotal role in lichen woodlands, a large ecosystem situated north of the closed-crown forest zone, and south of the forest-tundra zone. In Eastern Canada (Quebec), there is a remnant LW found 500 km south of its usual di...
Article
Lichens cover nearly 7% of the earth’s surface and in eastern Canada, lichen woodlands occupy over 300,000 km2. Reindeer lichens (genus Cladonia), are the main component of lichen woodlands and they play a crucial role in boreal forest ecology. We study, for the first time, the bacterial community of four species of reindeer lichens from eastern No...
Article
We tested the congruence in dispersal patterns of the two main symbionts of the lichen Cladonia stellaris using genotyping-by-sequencing data. Based on 122 samples from eastern Canada, we recovered more than 21000 loci from the photobiont of C. stellaris. We described the population structure and estimate genetic diversity of the photobiont and ide...

A checklist of all species of bryophytes, lycophytes, ferns, gymnosperms and angiosperms that are found in the wild (native, naturalised and casual) in Singapore is presented. We have attempted to account for all names of species and infraspecific taxa that have ever been recorded for Singapore, along with the pertinent publications that reported e...

Background and Aims Tremendous progress have been recently achieved in host-microbe research, however, there is still a surprising lack of knowledge in many taxa. Despite its dominance and crucial role in boreal forest, reindeer lichens have until now received little attention. We characterize, for the first time, the bacterial community of four sp...
Article
Introduction. Over the last years we have been engaged in studies of the South American Pottiaceae. Among the bryophyte specimens collected by us in central and northern Peru, some samples of a puzzling Pottiaceae were found. In this paper, we present our arguments for recognising these plants as a new species and its inclusion in Erythrophyllopsis...
Article
Didymodon buckii J.A.Jiménez & M.J.Cano is described as a new species from central Peru and northwestern Argentina. It is readily distinguished from all congeners by having bistratose to tetrastratose leaf margins from the apex to near the base and long-cylindric, thickened and deciduous leaf apices that are strongly channeled ventrally. Additional...

A revision of the Asiatic genus Pachyneuropsis H.A.Mill. (Pottiaceae, Bryophyta) recognizes two species, Pachyneuropsis bartlettii (E.B.Bartram) H.A.Mill. and P. perinvolutum (Tixier) comb. nov. Two names (Trichostomum hattorianum B.C.Tan & Z.Iwats. and Pachyneuropsis miyagii T.Yamag.) are synonymized with P. perinvolutum, and lectotypes are design...
Article
Names within Chionoloma tenuirostre are evaluated for proper taxonomic position. A total of 20 names are treated as synonyms, among them, 10 are here synonymised for the first time (Hyophila acutiuscula, Leptodontium subintegrum, Oxystegus cylindricus var. filifer, Trichostomum angustifolium, T. fallax, T. fallax f. minutum, T. fragilifolium, T. pr...
Article
Stephanodictyon borneense was described by Dixon and later combined to Trichostomum by Zander. Until now, it had been considered endemic to Malaysia, known only from the type locality on Lobang, Kinabalu (Sabah state). Here, its taxonomic position is assessed based on morphological data. Our results suggest that the combination into the genus Chion...
Article
A new species of Chionoloma Dixon, C. fractum M.Alonso, M.J.Cano & J.A.Jiménez, is described from Central and South America (Argentina, Belize, Bolivia, Brazil, Colombia, Ecuador, Panama, Peru and Venezuela). The species is distinguished morphologically by lanceolate or linear leaves, with apices usually broken, leaf margins strongly sinuous, basal...

Tres nuevos registros de musgos de los Andes del noroeste de Argentina. A partir de recolecciones recientes en la provincia de Salta (Argentina), se citan como novedad para este país dos musgos, Aligrimmia peruviana R.S. Williams y Conostomum cleistocarpum Herzog, considerados hasta ahora endémicos del Perú y Bolivia, respectivamente. Además, Cross...
Article
Chionoloma bombayense (Müll.Hal.) P.Sollman (Pottiaceae) has a long and complex taxonomic history. Recently it was viewed as a species with over 50 synonyms and considered the only species of the genus Pseudosymblepharis Broth., and later as Chionoloma Dixon, in Asia and Africa. Some phylogenetic studies have now suggested that more than one specie...
Article
Pottiaceae is the largest known moss family, with one of the most complex taxonomies among the bryophytes. The circumscription of genera within the Pottiaceae is challenging. Here, we elucidate the relationships among four related traditional genera of the Pottiaceae: Chionoloma, Oxystegus, Pachyneuropsis and Pseudosymblepharis, all sharing a compl...
Article
Pseudocrossidium crinitum, a dioicous moss distributed mainly in the Southern Hemisphere, has been treated as a single species, in spite of its phenotypical variability. Morphometric methods (PCA; DA) based on quantitative characters and molecular variation using plastid regions trnL-F and trnG of this species, as presently circumscribed, were anal...
Article
The mitochondrial genome of mosses is characterized by a highly conserved structure and genic content. This is confirmed here through the assembly and annotation of the mt genome of the moss Oxystegus tenuirostris, family Pottiaceae, for which it is assembled. A phylogenetic tree is inferred from the whole genome of 16 species of mosses to validate...
Article
Didymodon edentulus J.A. Jiménez & M.J. Cano, is described and illustrated as a new Andean species from the Cordillera Occidental in north-central Peruvian departments of Ancash, La Libertad and Lima. It is characterized mainly by its appressed leaves when dry, plane margins above midleaf, smooth laminal cells, oblate and transversely thick-walled...

A new species of Pseudocrossidium R.S.Williams, P. exiguum M.J.Cano & J.A.Jiménez, is described from South America (Argentina, Brazil and Peru). The species is distinguished morphologically by its lingulate to oblong-ovate leaves, leaf marginal cells not or scarcely differentiated from inner, costa ending below apex or percurrent, and semicircular...
Article
The Asian moss Pseudosymblepharis perlongifolia, previously known only from Malaysia, is reported for the first time for America on the basis of several collections from Maricao (Puerto Rico). The principal distinctive characters that separate it from the nearest species of Pseudosymblepharis and related genera are discussed. The species is describ...

Trichostomum schlimii Müll.Hal., a neglected Colombian taxon, is transferred to the genus Pseudosymblepharis Broth. as Pseudosymblepharis schlimii (Müll.Hal.) comb. nov. The species, known only from the type locality in Santa Marta, Colombia, is newly reported for the moss floras of Bolivia, Brazil, Dominican Republic, Ecuador, Guiana, Peru, and Ve...

The main goals are to (i) describe the microbial (bacteria and viruses) associated to reindeer lichens and underlying substrate, (ii) test the differences in the microbiome composition along a latitudinal gradient of Canadian Subarctic, (iii) correlate with geochemical, biotic and wind patterns and (iv) predict variations in the microbial community under future climatic global changes.
