... Forbs have higher nutrient content than grasses and less structural components like silica (Bråthen et al., 2021) being easier to decompose (Zhang et al., 2022). Litter quality has been shown to be the predominant factor controlling decomposition (Ayres et al., 2009;Murúa and Gaxiola, 2023), explaining >60% of the variability in decomposition rate at a global scale (Djukic et al., 2018). Therefore, communities with higher proportion of forbs, like the Atlas and Sierra Nevada, should have less recalcitrant litter (Bråthen et al., 2021), easier to decompose than in the Alps and Pyrenees. ...

... A recent study of carbon fluxes in a North-western Patagonian evergreen forest from southern South America (42°S) showed lower net ecosystem exchange (NEE), but higher biological activity (higher gross primary productivity and ecosystem respiration) compared to rainforests in the Northern Hemisphere (Perez-Quezada et al., 2018). This same forest was also found to store the largest C stock in the soil among temperate rainforests in the world (Perez-Quezada et al., 2021). ...

... We found that for the genus Azorella, it is the first time that bacteria of the genus Pseudoarthrobacter are detected. Previously, works such as those of Rodríguez-Echeverría et al. (2021) had detected abundant phyla such as actinobacteria for A. compacta and A. madreporica. However, among the bacteria identified, no actinobacteria were reported for A. prolifera. ...

... Likewise, it constitutes an area of ancestral connection between the indigenous peoples and nature. To preserve the tradition and customary coastal uses, local communities are claiming the management of the Guafo Island [33]. These island dwellers between the waters surrounding the island and the Gulf of Corcovado have also been considered for the delimitation of the coastal zones. ...

... The difficulty of sampling all host species from each of our trapping grids prevented spatiotemporal replication of our phylogenetic analyses, but cross-site comparisons of localized phylosymbiotic patterns would be instructive in light of prior work that has shown diets and microbiomes differ among populations (Amato et al., 2013. Both within and among small-mammal populations, individual-level variation in body size and body condition can occur through time as resource availability, diet quality, and population density vary (Farías et al., 2021;Long et al., 2017). Similarly, microbial communities comprise considerable genetic variation both within and among bacterial taxa that cannot be resolved using ...

... Wildfires are one of the most crucial disruptions that cause notable changes in the structure and function of forest ecosystems (Perez-Quezada et al., 2021). For example, it can mediate ecosystem dynamics and the carbon (C) cycle (Chen et al., 2020;Seidl et al., 2017). ...

... No obstante, en este estudio se observó que el hedor a cadáver expelido por la especie de planta S. chamaecyparissus, atraía a una gran cantidad de dípteros necrófagos y saprófagos de la familia Calliphoridae, y en que estos existían en un gran número en el entorno. Probablemente el cambio climático (Farré-Armengol et al., 2013;Kalin et al., 2019) y el escaso número de otros polinizadores como especies de Apidae, S. chamaecyparissus ha debido sintetizar y expeler nuevos aromas con el fin de atraer a otras especies de insectos para ser polinizadas (Hoballah et al., 2004;Benitez et al., 2012;Farré-Armengol et al., 2013) o probablemente existe una alteración de la discriminación de odorantes captados por el polinizador (Stopfer et al.,1997). Nosotros pensamos que son insectos polinizadores oportunistas y que debido a la escases de recompensas del ecosistema en que ha sido alterado o modificado, estos insectos han debido frecuentar este tipo de plantas con el fin de abastecerse del alimento proporcionado por S. chamaecyparissus. ...

... Yareta is documented in the dry and salt puna ecoregions and can grow at elevations between 3800 and 5200 masl. In Peru, it is not only typical for the dry puna but is also found in the periglacial zone (i.e., zona periglaciar) (Pugnaire et al., 2020;Ministerio del Ambiente, 2015, 2018. Yareta is a slow-growing cushion plant that grows on north slopes in arid and cold climates in volcanic landscapes and can reach thousands of years of age 2 (Pugnaire et al., 2020;Kleier et al., 2015;Kleier and Rundel, 2004;Ralph, 1978). ...

... However, Zhang et al. (2022) found that the relationship between mean annual precipitation and EMF exhibited an initial increasing and subsequent decreasing trend along an elevational gradient. In addition, most studies exploring the effects of climate factors on EMF have focused only on soil or plants (Zhang et al. 2022), ignoring the interaction of plants and soil that influence EMF in natural ecosystems (Pugnaire et al. 2019). Currently, studies on EMF predominantly focus on grassland ecosystems (Byrnes et al. 2014;Zhang et al. 2022). ...

... One key component in global carbon cycling is organic matter decomposition, where decomposer organisms and climatic variables, such as temperature and water availability, transform complex organic molecules into simpler molecules (Findlay, 2013), ushering the continuation of the carbon cycle. Decomposition of plant litter contributes greatly to ecosystem respiration and is responsible for a large part of carbon emission (Djukic et al., 2018). Decomposition processes lead to break down of complex molecules (short-term carbon release), but also to the stabilization of labile molecules (transformation of a fraction of labile molecules into recalcitrant molecules). ...
