    Abstract : Microorganisms, including two fungi, Phytophthora cryptogea and Fusarium oxysporum strain Fo-(IMI 386351), and one bacterium, Pesudomonas sp. strain MF30, were tested for their abilities to stimulate plant defence responses in tomato (Lycopersicon esculentum –L.) and to serve as effective biocontrol agents (Bs).

  4. 17. The Dawn of a New Age : Interrelationships of Acoela and Nemertodermatida and the Early Evolution of Bilateria

    Author : Andreas Wallberg; Ulf Jondelius; Mikael Thollesson; Graham Budd; Gonzalo Giribet; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acoela; Nemertodermatida; Bilateria; Metazoa; evolution; phylogenetic inferrence; ancestral reconstruction; taxon sampling; microRNA; Systematics and phylogenetics; Systematik och fylogeni; systematisk zoologi; Systematic Zoology;

    Abstract : Deciphering the rapid emergence of bilaterian animals around the time of the Cambrian Explosion and reconstructing the interrelationships of animal groups have long been two of the most elusive problems in Zoology. This thesis concerns the phylogenetic interrelationships within and among Acoela and Nemertodermatida, two groups of small worms that are believed to be basal bilaterians and which may provide important clues for understanding the early evolution of animals.

  5. 18. A multi-faceted approach to a "dark taxon" : The hyperdiverse and poorly known scuttle flies (Diptera: Phoridae)

    Author : Emily Hartop; Fredrik Ronquist; Torbjørn Ekrem; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity; taxonomy; dark taxa; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : Most of the unknown animal biodiversity on earth is in groups of invertebrates that are hyperdiverse and abundant, yet poorly known (“dark taxa”). The study of these organisms requires a multi-faceted approach and methodologies designed to tackle large numbers of species and specimens. READ MORE
