   Author : Sebastián Giraldo Gómez; [2023-06-14]
   Keywords : Posoquerieae; Cinchonoideae; Ixoroideae; Dialypetalanthoideae; Angiosperms 353; target capture; Hybpiper; Pollen Catapult Mechanism.;

   Abstract : The genus Posoqueria is a Neotropical group of shrubs and trees in the coffee family Rubiaceae. Posoqueria is phylogenetically poorly understood and presents several internal taxonomical difficulties. READ MORE

3. 2. A comparative study of the mosses Ptychostomum pseudotriquetrum and P. bimum : Investigating morphological characters, habitat, and distribution across northern Sweden

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Isabell Sjölander; [2023]
   Keywords : Ptychostomum pseudotriquetrum; Ptychostomum bimum; Crypsis; Leaf decurrency; northern Sweden;

   Abstract : The mosses Ptychostomum pseudotriquetrum and P. bimum (syn: Bryum, Bryophyta) are difficult to distinguish from each other, as they appear morphologically identical besides their difference in sexual condition. Because of their similarities, some researchers treat both as P. pseudotriquetrum, while others treat them as two distinct species. READ MORE

4. 3. Spruce associated Porodaedalea species distribution in Sweden

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Monica Guilera Recoder; [2022]
   Keywords : Fungi; Genetics; Porodaedalea;

   Abstract : Wood-inhabiting fungi have very important roles in the ecosystem in the degradation of dead wood by acting respectively as parasites and saprotrophs in boreal forests. Porodaedalea chrysoloma is a wood-decay parasite poroid fungi that is considered a key species in the old growth boreal forests. Due to forestry its habitat is declining. READ MORE

5. 4. Ancient plant cuticle chemistry: preservation and characterization of organic matter as biomarker of past UV-B radiation

   University essay from KTH/Kemi

   Author : Larissa Lopes Cavalcante; [2021]
   Keywords : UACs; fossil cuticle; p-coumaric acid; ferulic acid; UV-B proxy; micro-FTIR; confocal Raman microscope; UAF; fossil kutikula; p-kumarinsyra; ferulinsyra; UV-B-proxy; mikro-FTIR; konfokalt Raman-mikroskop;

   Abstract : Biologiska processer hos olika organismer påverkas av ultraviolett-B-strålning (UV-B). Kunskapen om förändringar i UV-B-flödet som nått planetens yta under det geologiska tidsspann sedan flercelligt liv uppstod är dock begränsad. READ MORE

6. 5. Aerotaxy-grown GaAs nanowires using Ga seed particles

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Eric Ceccarelli; [2021]
   Keywords : Aerotaxy; GaAs nanowires; epitaxy; self-catalized growth; self-seeded growth; Ga seeded GaAs nanowires; Ga seeded GaP nanowires; Technology and Engineering;

   Abstract : Aerotaxy offers an alternative method for the manufacturing of semiconductor nanowires. Instead of seeding growth on an expensive substrate, aerosol seed particles act as the catalyst for the Vapor–Liquid–Solid growth in a hot flow through reactor. READ MORE
