Temporal progress of Septoria leaf spot on rabbiteye blueberry (Vaccinium ashei) por Ojiambo, P., Scherm, H.

“…Septoria leaf spot, caused by Septoria albopunctata, is an important disease on blueberry in the southeastern United States, yet its epidemiology is largely unknown. Disease severity and dissemination of pycnidiospores were monitored from 2002 to 2004 in a planting of susceptible Premier rabbiteye blueberry to characterize the temporal progress of the disease and determine the effect of inoculum dynamics and selected leaf attributes on disease development. …”

Ecological and physiological thermal niches to understand distribution of Chagas disease vectors in Latin America por De La Vega, Gerardo, Schilman, Pablo Ernesto

“…Finally, we used phylogenetic independent contrasts to analyse the link between limiting factors and the thermal tolerance range for the assessment of ecological hypotheses that provide a different outlook for the geo-epidemiology of Chagas disease. In triatomines, thermo-tolerance range increases with increasing latitude mainly due to better cold tolerances, suggesting an effect of thermal selection. …”

Highly structured spatial models as a tool for analyzing the spread of diseases and species distributions por Martínez-Minaya, Joaquín, Vicent, Antonio, López-Quílez, Antonio, Picó, F.X., Marcer, A., Conesa, David

“…In the last years, the use of complex statistical models has increased to improve our knowledge on the spread of diseases and the distribution of species, being of great interest in Ecology and Epidemiology. Complexity in these models arises for instance when including the use of beta likelihoods and spatial e ects. …”

Identification of a new polymorphism in the MP/CP region of Spanish isolates of Grapevine Pinot gris virus por Morán, Félix, Predajna, Lukas, Katis, Nikolaos, Glasa, Miroslav, Ruiz-García, Ana B., Olmos, Antonio, Lotos, Leonidas

“…No association between the presence of these genetic variants and the symptomatology of Spanish GPGV infected grapevines has been found, suggesting that other factors would be involved in the epidemiology of the GPGV associated disease. These results give new insights in the study of GPGV genomic variability.…”

Outbreaks of African swine fever in domestic pigs in Gulu district, Uganda por Tejler, Emma

“…ASF is associated with severe sanitary and socio-economic consequences, in countries where it is endemic as well as in areas where it has recently been introduced. The epidemiology, involving a domestic and a sylvatic cycle, is complex. …”

Detection of African swine fever virus and phylogenetic characterization of Ornithodoros ticks collected from Lake Mburo - and Murchison Falls National Parks in Uganda por Lindström, Lisa
