“…Lower temperatures and consequent weaker microbial activity, nutrient limitations and decrease of primary decomposers limit decomposition rate at increasing altitude (Coûteaux et al 2002;Wilcke et al 2002), and therefore promoting soil organic carbon accumulation (Maraun et al 2008). Above-ground biomass, leaf area index and canopy height decrease with altitude while the restricted nutrient uptake leads to an increase in root production (Kottke et al 2008;Unger et al 2013). Although the above general patterns are widely documented, local conditions (e.g.…”

Tropical Andes are subjected to severe land use/land cover (LULC) changes that significantly alter the capacity of the landscape to provide ecological functions for supporting human well-being. The aim of the study is (a) to investigate the LULC changes in the Ecological Corridor Llaganantes-Sangay (Corredor Ecológico Llanganates-Sangay) (Central Ecuador), a buffer semi-protected area, during the period 2000-2014 and (b) to analyse their possible consequences on ecosystem services (ESs) provision. The analysis was performed using LULC maps of 2000, 2008 and 2014. ESs were analysed using the 'landscape capacity' index, which is based on a multi-criteria assessment framework. The study captured an extremely rapid LULC transition from croplands to pastures during 2008-2014 below the 2000-m altitude, which was followed by a respective rapid socioeconomic change of the local society. The landscape index changes were insignificant showing a slight decrease (−1.92%) during 2000-2014. Although the overall coverage of natural ecosystems slightly increased during 2000-2014, it was found that the passive landscape conservation might not be sufficient to maintain ESs provision. This was justified by the different ESs contribution between forest types but also by urbanization, agriculture abandonment and pasture expansion.

“…Several recent findings may be relevant to these potentially intertwined mycorrhizal histories. So far, we know that: (i) an arbuscular mycorrhizal glomeromycete fungus of the vascular plant Plantago can colonize the simple thalloid liverwort Pellia (Read et al 2000); (ii) the arbuscular mycorrhizal fungus Glomus mosseae can colonize the complex thalloid liverwort Conocephalum (Ligrone et al 2007); (iii) Glomus colonization produces mycorrhiza-like effects in another complex thalloid genus, Lunularia (Fonseca & Berbara 2008); (iv) the non-photosynthetic liverwort Cryptothallus mirabilis (now Aneura mirabilis) acquires carbon via a shared Tulasnella basidiomycete that forms ectomycorrhizas with Betula trees (Bidartondo et al 2003); (v) basidiomycete tulasnelloid fungi are not shared between the liverworts Aneura and Riccardia and some epiphytic orchids (Kottke et al, 2008); (vi) basidiomycete sebacinoid fungi associated with three specimens of leafy liverworts (Kottke et al 2003); and (vii) basidiomycete -liverwort symbioses may be more specific than ascomycete-liverwort symbioses (Chambers et al 1999;Duckett et al 2006a). These suggestive but fragmentary data are inadequate for accurately inferring and comparing the seminal early events in the evolution of land plant -fungal symbioses including mycorrhizas (Nebel et al 2004;Kottke & Nebel 2005).…”

Liverworts, the most ancient group of land plants, form a range of intimate associations with fungi that may be analogous to the mycorrhizas of vascular plants. Most thalloid liverworts contain arbuscular mycorrhizal glomeromycete fungi similar to most vascular plants. In contrast, a range of leafy liverwort genera and one simple thalloid liverwort family (the Aneuraceae) have switched to basidiomycete fungi. These liverwort switches away from glomeromycete fungi may be expected to parallel switches undergone by vascular plants that target diverse lineages of basidiomycete fungi to form ectomycorrhizas. To test this hypothesis, we used a cultivation-independent approach to examine the basidiomycete fungi associated with liverworts in varied worldwide locations by generating fungal DNA sequence data from over 200 field collections of over 30 species. Here we show that eight leafy liverwort genera predominantly and consistently associate with members of the Sebacina vermifera species complex and that Aneuraceae thalloid liverworts associate nearly exclusively with Tulasnella species. Furthermore, within sites where multiple liverwort species co-occur, they almost never share the same fungi. Our analyses reveal a strikingly conservative ecological and evolutionary pattern of liverwort symbioses with basidiomycete fungi that is unlike that of vascular plant mycorrhizas.
