To understand the phylogenetic relationships and evolution of the powdery mildew genus Sawadaea (Ascomycota: Erysiphaceae), obligate parasitic fungi of maples, we performed molecular phylogenetic analyses based on 47 ITS and ten 28S rDNA sequences. Seven major clades of Sawadaea, each represented by powdery mildew specimens collected from a single or a small number of closely related sections o...

The paper focuses on the extension of the ACER method for prediction of extreme value statistics to the case of bivariate time series. Using the ACER method it is possible to provide an estimate of the exact extreme value distribution of a univariate time series. This is obtained by introducing a cascade of conditioning approximations to the exact extreme value distribution. When this cascade h...

This thesis addresses the corporate strategies IT firms in international market. In particular, it investigates Acer Corporation leading IT company headquartered in Taiwan. Acer's business model was distinctly different from traditional conglomerate corporate structures in Taiwan. Founded in 1981, Acer developed in to a leading semiconductor company in the world by using a combination of manufa...

BACKGROUND Atypical myopathy (AM) in horses is caused by the plant toxin hypoglycin A, which in Europe typically is found in the sycamore maple tree (Acer pseudoplatanus). Owners are concerned about whether their horses are in danger if they graze near maple trees. HYPOTHESIS/OBJECTIVES To measure hypoglycin A in the most common maple tree species in the Netherlands, and to determine whether ...

The evolution of breeding systems was studied in the genus Acer, with special attention to the origin of androdioecy and dioecy, using a phylogenetic approach. Parsimony and maximum-likelihood techniques were used to infer the ancestral character state and trends in the evolution of breeding systems. Information on breeding systems was obtained from the literature, and phylogenetic relationship...

Asian longhorned beetle (ALB), Anoplophora glabripennis (Motschulsky), is an invasive insect that has successfully established multiple times in North America. To investigate host colonization and reproductive success (exit holes/eggs), two ALB infested forest stands were sampled in central Massachusetts, USA. Infested Acer platanoides L., Acer rubrum L., and Acer saccharum Marsh. were felled, ...
