Many Teratosphaeria species are associated with leaf diseases on Eucalyptus spp. (Myrtaceae). However, only a few of these are major pathogens that cause serious losses, particularly to plantation forestry globally. Several species in the Teratosphaeraceae and Mycosphaereaceae species are known to occur in Uruguay where they cause leaf and shoot diseases on Eucalyptus plantations, but most are of minor importance. However, two species have had a serious negative impact on the performance of certain Eucalyptus species. Since its first detection in 2007, Teratosphaeria nubilosa has eliminated Eucalyptus globulus from the available species for pulpwood production. Species substitution has been the main management tool for this pathogen resulting in negative consequences such as limited access to external markets. More recently, in 2011, Teratosphaeria pseudoeucalypti was reported causing leaf blight that has resulted in severe defoliation and death of established Eucalyptus camaldulensis, E. tereticornis, and their hybrids. This pathogen was first described in Australia in 2010 and simultaneously reported in Argentina, Brazil and Uruguay four years later. This disease is a serious threat to Uruguayan plantations and has already imparted a significant social and economic impact in the country where it has damaged urban parks and plantations used for shelter and shade for livestock production. These two examples of serious diseases caused by Teratosphaeria spp. have highlighted that accidentally introduced non-native pathogens can have in a country. They have also raised concerns that such pathogens could threaten the many native Myrtaceae found natural forest ecosystems in Uruguay.

There are several plant below-ground biomass databases for grasslands, but the contribution from the southern hemisphere is minimal. Particularly, no study has compiled the published values of plant below-ground biomass for the temperate subhumid grasslands of South America. In these grasslands, called Río de la Plata grasslands, grazing is the most frequent disturbance. We set two objectives: (1) to compile and synthesize data of four variables: below-ground biomass, fraction of total biomass allocated below-ground, below-ground net primary productivity and below-ground biomass turnover rate; (2) to estimate the effect of grazing exclusion on below-ground biomass by means of a meta-analysis. There are 15 studies published on six out of eight regional sub-divisions of the Río de la Plata grasslands. © 2023 Ecological Society of Australia. |
