BACKGROUND: 2-phenylethanol (PEA) is a higher aromatic alcohol with a rose-like odor, which is used in several industries. Although PEA can be synthesized, consumers are increasingly concerned about the toxicity of chemically synthesized products, and prefer natural aroma compound. PEA occurs naturally in the environment but concentrations are too...
Article
Araujia hortorum is a perennial, broad-leaved herbaceous climber native to South America considered an invasive weed in New Zealand and several other countries where it has been introduced. Ascochyta araujiae and Septoria araujiae are the causal agents of two of the most frequently encountered diseases affecting natural populations in Argentina, wh...
Article
Identification and naming of fossil and subfossil organisms are not easy tasks. We are in the midst of a paradigm shift in how NPP taxa are named, driven in large part by 1) molecular clock taxonomic efforts in the past 25 years and 2) greater connectivity among scientific communities. Concurrent with this is the understanding that sometimes a name...
Article
Fungal spores are increasingly used as reliable proxies in paleoenvironmental reconstructions; however, little attention is paid to the ecological tolerances of the fungi themselves and the signal the fungi provide. This chapter provides a much-needed background in fungal biology and ecology of monophyletic Dikarya (Ascomycota and Basidiomycota), a...

The driving forces behind many soil processes are microorganisms and they are able to respond immediately to environmental changes. The soil microbial community impacts on many soil properties. More than one-third of the terrestrial ecosystems are semiarid. However, a limited number of studies have been conducted to characterize soil fungal communi...

The South American vine Araujia hortorum (Apocynaceae) is now considered an invasive species in many countries. In New Zealand it has been targeted for biological control. In its native range in Argentina it is frequently affected by cercosporoid fungi but little is known about the diseases they cause. These pathogens produce no, or scarce, conidia...

We analyzed a peat-bog sequence from the central region of Tierra del Fuego, southernmost Patagonia, to reconstruct the environmental changes over the past 15,000 years. Postglacial vegetation was mainly composed by grasslands and shrubby communities with sparsely distributed Nothofagus trees under dry conditions. The predominance of Glomus sp. and...

Soil microorganisms are vital for ecosystem functioning because of the role they play in soil nutrient cycling. Agricultural practices and the intensification of land use have a negative effect on microbial activities and fungal biomass has been widely used as an indicator of soil health. The aim of this study was to analyze fungal biomass in soils...
