  2. 11. Morphological and chemical leaf traits of tropical montane tree species and their responses to warming

    Author : Manishimwe Aloysie; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tropical montane forests; tropical trees; leaf morphology; leaf nutrients; warming climate; climate change;

    Abstract : Leaf morphological and chemical traits of tropical trees vary along climate gradients, but it is currently unclear how they will respond to a rapidly warming climate and how this will vary among species. Considering this, tropical trees native to East and Central Africa were investigated in three complementary studies in Rwanda. READ MORE

  4. 12. SAWING STRATEGIES FOR TROPICAL HARDWOOD SPECIES : Simulation studies based on industrial conditions of Mozambique

    Author : Pedro Ah Shenga; Dick Sandberg; Olof Broman; Mats Nylinder; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sawing strategies; tropical hardwood species; simulation; volume yield; log grading; umbila; jambirre; Träteknik; Wood Science and Engineering;

    Abstract : The harvesting of Mozambique tropical hardwood species is considerable higher than the natural regrowth in the forest and the stock is decreasing drastically. Therefore, it is important to improve the material recovery when the wood is refined (i.e., in sawing and further refinement to products such as joineries, furniture etc. READ MORE

  5. 13. Tropical aspects of real polynomials and hypergeometric functions

    Author : Jens Forsgård; Boris Shapiro; Grigory Mikhalkin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amoeba; Tropical Geometry; Hypergeometric function; Geometry of zeros; Discriminant; Mathematics; matematik;

    Abstract : The present thesis has three main topics: geometry of coamoebas, hypergeometric functions, and geometry of zeros.First, we study the coamoeba of a Laurent polynomial f in n complex variables. We define a simpler object, which we call the lopsided coamoeba, and associate to the lopsided coamoeba an order map. READ MORE

  7. 15. Phytoplankton and bacterioplankton dynamics in a polymictic tropical lake

    Author : Rolf Erikson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; tropical lake; algae; bacteria; regulation; dynamics; interaction; Biologi; Biology; Biologi; limnologi; Limnology;

    Abstract : Phytoplankton and bacterioplankton dynamics in lakes are regulated by a multitude of factors such as light, temperature, water column mixing, nutrients, organic substrates, grazing, and food web structure. Tropical lakes are especially interesting to study because of the relative constancy of several of these factors. READ MORE
