Amanita muscaria , an ectomycorrhizal fungus native to the Northern Hemisphere, has been presumably introduced to Patagonia via exotic pine plantations. Recent findings confirm its presence in pure Nothofagus forests within several National Parks. Morphological and molecular analyses verified its association with N. dombeyi and N. pumilio , showing...

Climate change (CC) projections for western Patagonia expect an increase of 1°C - 3°C in temperature and 10% to 30% of decrease in precipitation by the end of this century. This shift could significantly impact on the Nothofagus forests, which are widely distributed in the Andean-Patagonian mountains. These species depend on ectomycorrhizal fungi t...

Las proyecciones de Cambio Climático indican, para el oeste de Patagonia, mayor frecuencia de incendios, poniendo en riesgo la subsistencia de los bosques nativos. Las especies de Nothofagus que conforman los bosques subantárticos, se desarrollan de modo obligado con hongos ectomicorrícicos (EcM), vitales para el mantenimiento de estos ecosistemas....

The forest of Araucaria araucana (“pewen” in Mapuche language), with its associated species of the genus Nothofagus, is unique from an evolutionary, biological and sociocultural point of view. Due to the interdependence and interrelation with the Mapuche-Pewenche people, it is considered a biocultural ecosystem. This work is a comprehensive binatio...

Mycorrhizas are one of the most important and ecologically crucial symbiosis for boreal, temperate, subtropical, and tropical forests, driving plant population biology and community ecology, shaping their dispersal and establishment, regulating plant coexistence. Forest fragmentation, clear-cutting, fires, grazing, and partial conversion to exotic...

El equilibrio de los ecosistemas se ve afectado por la frecuencia y gravedad de las sequías consecuentes del aumento de temperatura y disminución de las precipitaciones en el contexto de Cambio Climático (CC). Las especies de Nothofagus que conforman los bosques subantárticos, forman asociaciones ectomicorrícicas (ECM) obligadas, que impactan posit...

This paper is a contribution to the current knowledge of taxonomy, ecology and distribution of South American Cortinarius (Pers.) Gray. Cortinarius is among the most widely distributed and species-rich basidiomycete genera occurring with South American Nothofagaceae and species are found in many distinct habitats, including shrublands and forests....

Since 2015, Araucaria araucana, an ecologically and economically important conifer native to Argentina and Chile, has suffered an unusual partial death of the crown throughout almost all of the distribution range in Argentina. No primary pathogen or pest was evident, associated with the phenomenon. Isolates of Mortierella, a poorly studied fungal g...

The southernmost portion of the Andes in South America hosts Nothofagaceae forests that form ectomycorrhizal (EcM) associations. We compiled all the published reports of EcM taxa from these woodlands, based on fruit-body collections and molecularly identified root tips. This resulted in 87 peer-reviewed research papers dealing with EcM associations...

Phytophthora austrocedri is a pathogen of Austrocedrus chilensis causing “Mal del Ciprés” (cypress sickness) in Patagonia and killing Juniperus communis in Britain, along with other species in the Cupressaceae. The evident association of the pathogen with members of the Cupressaceae makes it necessary to study the susceptibility of other species re...

Cortinarius magellanicus Speg. is an edible, ectomycorrhizal fungus, widely distributed in Argentina, Chile and New Zealand. However, earlier studies already indicated that the epithet ‘magellanicus’ might have been applied in a wide sense, thus circumscribing several species. A neotype was designated by Moser and Horak (1975) due Spegazzini's type...

A fines del año 2015 se detectó una inusual muerte parcial de copa en el Pehuén (Araucaria araucana) conífera endémica, escasa y de distribución restringida en Chile y Argentina. La desecación fue detectada inicialmente por organismos chilenos (CONAF y SAG) los cuales informaron de la situación a la Argentina. Una prospección preliminar realizadas...

Tomentella (Thelephorales, Basidiomycota) in Nothofagaceae forests of Patagonia, Argentina: mycorrhizae of new species. Tomentella is a mycorrhizal genus whose presence in temperate, tropical and circumpolar forests has been widely reported. It typically forms ectomycorrhizae (EM), but also orchidioid, ericoid, monotropoid and arbutoid symbiosis. T...

Los bosques de Nothofagus son altamente dependientes de sus pares mutualistas fúngicos, llamados micorrizas. Pero ¿qué pasa cuando los bosques son invadidos por coníferas exóticas? ¿Cambian las comunidades micorrícicas? ¿Interactúan con las propiedades suelo o solo dependen del hospedante? ¿Puede el sotobosque ayudar a algunas de las especies arbór...

Pseudotsuga menziesii, one of the most widely planted exotic Pinaceae in NW Patagonia (Argentina), has been introduced in different environmental conditions showing an invasive behavior on neighboring Nothofagus forests. Recent researches have shown high abundance of ecto- (EM) and ectendomycorrhiza in Ps. menziesii seedlings from Patagonia but the...

Temperate forests of southern Argentina and Chile cover a wide latitudinal and altitudinal range on both sides of the Andes, with Nothofagus species being one of the main tree species. Most of the larger remnants are protected within the limits of national parks and forest reserves. However, some of these are invaded by exotic conifers such as Pseu...

The temperate forests of southern Argentina and Chile covers a wide latitudinal and altitudinal range on both slopes of the Andes, Representing an area of 6.5 million hectares of native forests and woodlands. Forests resource has additionally has about 2 million hectares suitable for afforestation with fast-growing exotic species, such as Pseudotsu...

Pseudotsuga menziesii is one of the most widely planted conifers in the Patagonian Andes of Argentina, with invading characteristics that are widely reported. Nevertheless, little is known about the role of its obligate mycorrhizal associations in limiting or fostering the establishment of invading seedlings. We studied the richness and abundance o...

We investigated if Pinus ponderosa plantations in Patagonia are able to produce viable mycorrhizal inocula towards adjacent grasslands, which only harbor endomycorrhizal vegetation. We hypothesized that these inocula have the potential to contribute to the establishment of naturally disseminated seedlings. Also, we determined the main fungal taxa i...

Ponderosa pine (Pinus ponderosa Dougl. ex P. & C. Laws.), an ectomycorrhiza (EM) dependent species, has been widely introduced in Patagonia, Argentina. This study used morphotyping, restriction analysis, and sequencing of EM root tips from ponderosa pine seedlings in two nurseries to assess the complete EM fungus (EMF) richness, to confirm doubtful...

Repetidos reportes de plantadores de la zona cordillerana del Chubut (Argentina) han señalado que las plántulas de Pinus ponderosa, especie ectotrófica obligada, producidas bajo invernáculo con fertirriego y sin aplicación de inoculantes ectomicorrícicos, que presentaban baja o nula infección ectomicorrícica al terminar la etapa de vivero, mostraro...

Several reports of tree planters from the Patagonian Andes region of Chubut (Argentina) have pointed out that seedlings of Pinus ponderosa, obligate ectotrophic species, produced in greenhouses with high levels of fertilization without ectomycorrhizal inoculum applications, showed low or null ectomycorrhizal infection at the end of nursery stage bu...

En el año 2004, los alumnos de la cátedra asistidos por el equipo docente y por los técnicos de INTA trabajaron en un análisis más detallado de la información existente, proveniente principalmente de las parcelas de muestreo permanente –PMP- y de información expresamente obtenida de la remedición de dichas parcelas. Se incluyó en esa oportunidad la...
