A tradeoff between fitness‐related traits mask facilitation in a semiarid ecosystem
Molina-Montenegro, Marco A.; Baldelomar, Mariela; Atala, Cristian; Torres-Díaz, Cristian (2020)In stressful environments, a nurse plant can ameliorate harsh biotic and abiotic conditions for another plant species that grows within its canopy. This canopy can act as a barrier for herbivores, reducing damage to the ...

Assessing the importance of native mycorrhizal fungi to improve tree establishment after wildfires
Atala, Cristian; Reyes, Sebastián A.; Molina-Montenegro, Marco A. (2023)The Chilean matorral is a heavily threatened Mediterranean-type ecosystem due to humanrelated activities such as anthropogenic fires. Mycorrhizal fungi may be the key microorganisms to help plants cope with environmental ...

Bioactive lichen secondary metabolites and their presence in species from Chile
Poulsen-Silva, Erick; Gordillo-Fuenzalida, Felipe; Atala, Cristian; Moreno, Adrián A.; Carolina Otero, María (2023)Lichens are symbiotic organisms composed of at least one fungal and one algal species. They are found in different environments around the world, even in the poles and deserts. Some species can withstand extreme abiotic ...

Differential impact of an eclipse on photosynthetic performance of trees with different degrees of shade tolerance
Molina-Montenegro, Marco A.; Atala, Cristian; Carrasco-Urra, Fernando (2021)Solar eclipses represent a natural and unexpected event for plants that can potentially affect photosynthetic performance at the individual level. This effect, however, has seldom been evaluated. Here, we measured the ...

Fungal symbionts enhance N-uptake for Antarctic plants even in non-N limited soils
Acuña-Rodríguez, Ian S.; Galán, Alexander; Torres-Díaz, Cristian; Atala, Cristian; Molina-Montenegro, Marco A. (2020)Plant-fungi interactions have been identified as fundamental drivers of the plant host performance, particularly in cold environments where organic matter degradation rates are slow, precisely for the capacity of the fungal ...

Inoculation with extreme endophytes improves performance and nutritional quality in crop species grown under exoplanetary conditions
Molina-Montenegro, Marco A.; Escobedo, Victor M.; Atala, Cristian (2023)Introduction: Technological advances have made possible long space travels and even exoplanetary colonies in the future. Nevertheless, the success of these activities depends on our ability to produce edible plants in ...

Positive interaction between shrubs and native orchids in a Mediterranean ecosystem
Atala, Cristian; Baldelomar, Mariela; Torres-Díaz, Cristian; Pereira, Guillermo; Cacciuttolo, Felipe; Vargas, Reinaldo; Molina-Montenegro, Marco A. (2020)In the Mediterranean portion of Central Chile, where anthropic disturbances are common and severe, precipitations could drastically decrease and temperatures increase due to climate change. In this ecological context, ...

Root endophytic Penicillium promotes growth of Antarctic vascular plants by enhancing nitrogen mineralization
Oses-Pedraza, Rómulo; Torres-Díaz, Cristian; Lavín, Paris; Retamales-Molina, Patricio; Atala, Cristian; Gallardo-Cerda, Jorge; Acuña-Rodríguez, Ian S.; Molina-Montenegro, Marco A. (2020)Fungal endophyte associations have been suggested as a possible strategy of Antarctic vascular plants for surviving the extreme environmental conditions of Antarctica. However, the mechanisms by which this occurs are still ...

Symbiotic interaction enhances the recovery of endangered tree species in the fragmented maulino forest
Torres-Díaz, Cristian; Valladares, Moisés A.; Acuña-Rodríguez, Ian S.; Ballesteros, Gabriel I.; Barrera, Andrea; Atala, Cristian; Molina-Montenegro, Marco A. (2021)Beneficial plant-associated microorganisms, such as fungal endophytes, are key partners that normally improve plant survival under different environmental stresses. It has been shown that microorganisms from extreme ...

Top-down and bottom-op effects deployed by a nurse shrub allow facilitating an endemic mediterranean orchid
Baldelomar, Mariela; Atala, Cristian; Molina-Montenegro, Marco A. (2019)Aims: Facilitation among plant species occurs when the presence of one species, the so-called nurse, alters the environment in a way that enhances the growth, survival or reproduction of a second species. This positive ...
