{"title":"Lichen Community Assemblages and Functional Traits as Indicators of Vegetation Types in Central Mexico, Based on Herbarium Specimens","authors":"Diego Simijaca, G. Ocampo, J. Escoto-Moreno, R. Pérez‐Pérez","doi":"10.5252/cryptogamie-mycologie2023v44a6","DOIUrl":"https://doi.org/10.5252/cryptogamie-mycologie2023v44a6","url":null,"abstract":"ABSTRACT Despite the growing interest in the lichen communities of Mexico, little is known about the assemblages from the central part of the country. For that reason, we defined the following research objectives: 1) to compare species richness, composition, and dissimilarity of lichen communities among three vegetation types; 2) to explore the incidence of environmental variables on lichen community species composition; and 3) to identify species and functional traits indicative of each vegetation type. Based on lichens' collection of Aguascalientes (HUAA herbarium), the relationships between species, traits, and environmental variables were represented through beta diversity components, non-metric multidimensional scales, Indicator Species Analysis, and Fourth Corner Analysis. In total, 218 lichen species were found, 132 in Quercus L. forests, 90 in subtropical shrubland, and 85 in xerophytic shrubland. Vegetation types had beta diversity total values higher than 0.8, although paired comparisons revealed variations in species replacement and richness. The indicator species identified for Quercus forests were Parmotrema acutatum Kurok., while for subtropical shrubland Phaeophyscia nashii Essl. and Physcia biziana (A.Massal.) Zahlbr. No indicator species were identified for xerophytic shrubland. Functional traits indicative of xerophytic shrubland were crustose lichens and the saxicolous substrate. Subtropical shrubland indicators comprised soredia and foliose narrow lobes, whereas indicators of Quercus forest consisted of foliose wide lobes and the epiphyte substrate. The functional trait approach used in the study of Mexican lichen communities is highly recommended given the observed similarities between taxonomical and functional community assemblages and the ease with which the functional traits approach links species composition to environmental variables.

Thalli of the Cladonia chlorophaea species group with horizontal primary thalline lobes and sorediate, cup-, funnel-, goblet- or wineglasss-shaped podetia contain twelve different lichen secondary metabolites (atranorin, congrayanic, cryptochlorophaeic, 4-O-methyl-cryptochlorophaeic, fumarprotocetraric, grayanic, 4-O-demethyl-grayanic, homosekikaic, merochlorophaeic, norrangiformic, quaesitic, rangiformic and thamnolic acids) in various combinations. Six taxa are currently distinguished at species level based mainly on these substances. The 281 specimens kept in herbaria as Cladonia chlorophaea s.l. collected in Hungary were analysed by high performance thin-layer chromatography (HPTLC). The chemical revision allowed to separate C. asahinae J.W.Thomson, C. cryptochlorophaea Asahina, C. grayi G.Merr. ex Sandst., C. merochlorophaea Asahina and C. novochlorophaea (Sipman) Brodo & Ahti from C. chlorophaea s.str. Three species – C. asahinae, C. grayi and C. novochlorophaea – represent new distribution records to Hungary. The morphological characters differentiating these species according to the literature data were less obvious. Therefore, a detailed morphometric study of 227 podetia – considering the size of podetia, cup, stalk, soredia and squamules – was carried out on selected specimens. Although Cladonia asahinae and C. cryptochlorophaea were usually smaller than the robust C. chlorophaea (Flörke ex Sommerf.) Spreng. or C. merochlorophaea, the chemical characteristics supplied more stable results than morphological metrics.

Phylogenetic analyses based on a combination of four genomic regions, including the partial nuclear 28S ribosomal DNA (LSU), internal transcribed spacer regions 1 and 2 including the intervening 5.8S nuclear ribosomal DNA (ITS), partial β-tubulin (tub2) and RNA polymerase II second largest subunit (rpb2), are provided to clarify the phylogenetic affinities of the new species and other taxa within the Microsphaeropsis complex. In addition, a new genus Heteromicrosphaeropsis M.Mehrabi-Koushki, K.D.Hyde & Jayaward., gen. nov. and five new combinations are introduced. The new combinations are Heteromicrosphaeropsis ononidicola (Thambug., Camporesi & K.D.Hyde) M.Mehrabi-Koushki, K.D.Hyde & Jayaward., comb. nov., Microsphaeropsis cytisi (W.J.Li & K.D.Hyde) M.Mehrabi-Koushki, K.D.Hyde & Jayaward., comb. nov., M. cytisicola (Wanas., Camporesi, E.B.G.Jones & K.D.Hyde) M.Mehrabi-Koushki, K.D.Hyde & Jayaward., comb. nov., M. cytisinus (Tennakoon, Camporesi & K.D.Hyde) M.Mehrabi-Koushki, K.D.Hyde & Jayaward., comb. nov. and M. minima (W.J.Li & K.D.Hyde) M.Mehrabi-Koushki, K.D.Hyde & Jayaward., comb. nov. RÉSUMÉ Révision du complexe Microsphaeropsis avec l'ajout de quatre nouvelles espèces de Paramicrosphaeropsis L.W.Hou, L.Cai & Crous provenant d'arbres de la forêt zagrosienne en Iran. Paramicrosphaeropsis L.W.Hou, L.Cai & Crous est un taxon monophylétique de la famille des Didymellaceae et comprend, à ce jour, deux espèces. Lors d'une étude sur les champignons de type Microsphaeropsis associés aux arbres de la forêt zagrosienne en Iran, quatre nouvelles espèces de Paramicrosphaeropsis ont été identifiées et décrites, dont P. amygdalus M.Mehrabi-Koushki, S.Artand, K.D.Hyde & Jayaward., sp. nov. d'Amygdalus scoparia Spach., P. pistacicola M.Mehrabi-Koushki, S.Artand, K.D.Hyde & Jayaward., sp. nov. de Pistacia spp., P. salandica M.Mehrabi-Koushki, S.Artand, K.D.Hyde & Jayaward., sp. nov. de Crataegus sp., Nerium oleander L., Quercus brantii Lindl. et Ziziphus sp., et P. zagrosensis M.Mehrabi-Koushki, S.Artand, K.D.Hyde & Jayaward., sp. nov. de Crataegus sp. et Quercus brantii.
