Teratosphaeria pseudoeucalypti was first discovered in Queensland, Australia in 2010 causing a serious leaf blight disease known as Kirramyces Leaf Blight (KLB) on Eucalyptus commercial plantations. The pathogen was subsequently reported in 2014 in Argentina, Brazil and Uruguay, representing the first occurrence outside Australia. During 2015, a survey was conducted to assess prevalence, incidence and severity of KLB on Eucalyptus camaldulensis and E. tereticornis in Uruguay. A total of 80 plantations were visited, including these species and their hybrids. In each plantation, one transect of 20 trees in a row was scored for crown damage, based on percentage of defoliation and overall disease severity. The disease was found in all regions of the country. There was no clear pattern of distribution or severity of the disease with a distribution appearing to be generalized. Classification and regression tree analysis indicated that host species was the most important segregating factor based on severity, were E. tereticornis plantations showed a significantly lower severity than E. camaldulensis and their hybrids. KLB is widespread and serious on susceptible Eucalyptus spp., posing a threat to commercial plantation forestry in Uruguay. Future studies will concentrate on understanding the genetic diversity of a large collection of isolates that have emerged from this study and on selecting planting stock resistant to KLB. |

Abstract:
We report State-and-Transition Models for Uruguayan grasslands built upon a methodological approach that objectively defined states/phases associated, a priori, to rangeland management. Such approach was based on randomly sampled areas corresponding to mapped grassland communities. Each sampled area matched a MODIS pixel. Vegetation structural indicators were recorded in every pixel. After a multivariate analysis, field observations were grouped according to similarities in terms of structure, and different "states" and "phases" were identified. Ecosystem functioning and the supply of regulating ecosystem services were estimated for each grassland state/phase using the normalized difference vegetation index (NDVI) derived from MODIS sensor. Finally, workshops were held in order to detect local stakeholders? perceptions, and to discuss the management practices to promote the desired transitions among phases. Results were presented for two vegetation units of the Basaltic ?Cuesta? region. The ?inductive approach? applied not only led to the description of ?states?, but also to the identification of more subtle changes in vegetation ("phases"). Our approach minimized biases due to personal experience as well as differences derived from using different observation protocols. The two vegetation units presented an internal heterogeneity associated to changes in basal stratum height, total cover, stratification, frequency of decreasing species due to grazing, and proportion of plant functional types. The ecosystem functioning descriptors of each phase responded to extreme climatic events differently. Based on stakeholder?s opinions and experiences, stocking rate, sheep/cattle ratio, and grazing method were the main management practices promoting the transition among phases. MenosAbstract:
