  1. 1. Climbing the Trichoptera Tree : Investigations of Branches and Leaves

    Author : Tobias Malm; Kjell Arne Johanson; Wolfram Mey; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Trichoptera; Leptoceridae; Symphitoneuria; Gracilipsodes; Triplectides; morphology; DNA; systematics; phylogeny; New Caledonia; Madagascar; new species; new genus; Systematics and phylogenetics; Systematik och fylogeni; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : The Trichoptera (caddisflies) is the largest of the primary aquatic insect orders, currently including more than 13,500 species. With more than 100 species new to science described annually, the known caddisfly diversity is rapidly increasing. In the first four papers of this Thesis, a total of 22 species new to science are described. READ MORE

  2. 2. Refixation of respiratory CO2 in leaves

    Author : Diana Eckert; Anna M. Jensen; John Marshall; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2 refixation; mesophyll resistance; stomatal conductance; Vcmax; leaf anatomy; photosynthesis; forestry; carbon allocation; ecophysiology; Natural Science; Naturvetenskap;

    Abstract : Photosynthesis is a vital process for trees, one in which CO2 plays a major role. At the same time, the tree’s own metabolism produces CO2. READ MORE

  3. 3. A tale of trees and leaves : subtrees and local convergence

    Author : Wang Ruoyu; Stephan Wagner; Haslegrave John; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tree; subtree; mean subtree order; Benjamini Schramm convergence; local convergence; Mathematics; Matematik;

    Abstract : Given a tree T, a subtree in T is a subgraph that is a tree itself. The set of subtrees in a tree is related to many important graph parameters, one of which is the mean subtree order. READ MORE

  4. 4. Predicting who stays or leaves after the acquisition: : Target’s top manager turnover

    Author : Keivan Aghasi; Terrence Brown; Massimo Colombo; Maureen McKelvey; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Acquisition; CEO turnover; TMT turnover; coordination; Founder-CEO; Similarity attraction; Diversity;

    Abstract : In acquisition of high-tech and knowledge intensive firms, scholars have paid special attention to top managers’ status after the deal. Literature suggests that these managers in particular CEOs if kept in post-acquisition provide coordination capacity for the acquirer to transfer the knowledge and technology from the target to the acquirer while minimizing the disruptive effect of post-acquisition integration process.

  5. 5. Carbohydrate Levels and Fructan Metabolism in Barley (Hordeum vulgare L.) Leaves : effects of manipulating mineral nutrition and photosynthesis

    Author : Changwen Wang; Björn Thorsteinsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysiologisk botanik; Physiological Botany;

    Abstract : Carbohydrate levels and fructan metabolism were studied in the leaves of barley (Hordeum vulgare L. cv. Agneta) plants subjected to phosphorous (P)-deficiency, nitrogen (N)-deficiency and N-resupply following the N-deficiency. READ MORE
